Comparing the Effects of Home Versus Clinic-Based Parent Training for Children with Autism
Research with parents on managing child problem behavior typically measures either child or parent behavior. This study was designed to evaluate the effectiveness of training parents to implement a function-based behavior intervention plan (BIP) in a non-trained natural environment utilizing a Multiple Probe Design across Participants. Participants included four parent-child dyads. Measurement variables included parents' use of effective and ineffective strategies and child problem behavior. Intervention involved training parents to understand and implement the BIP using effective strategies, modeling the effective procedures, and providing feedback following parent implementation of procedures. Results showed that the intervention was very effective in promoting skill generalization of parents and decreasing child problem behavior. The findings have implications for research and clinical practice.
Determination of the Optimal Number of Strata for Bias Reduction in Propensity Score Matching.
Previous research implementing stratification on the propensity score has generally relied on using five strata, based on prior theoretical groundwork and minimal empirical evidence as to the suitability of quintiles to adequately reduce bias in all cases and across all sample sizes. This study investigates bias reduction across varying number of strata and sample sizes via a large-scale simulation to determine the adequacy of quintiles for bias reduction under all conditions. Sample sizes ranged from 100 to 50,000 and strata from 3 to 20. Both the percentage of bias reduction and the standardized selection bias were examined. The results show that while the particular covariates in the simulation met certain criteria with five strata that greater bias reduction could be achieved by increasing the number of strata, especially with larger sample sizes. Simulation code written in R is included.
Alternative Certification: A Comparison of Factors Affecting the Motivations of General and Special Educators
This study was developed to examine the motivations of individuals who chose alternative routes to teacher certification and what they believe were the strengths and weaknesses of their alternative certification preparation (ACP). Data accrued from this study were based on a 55-item online survey and participant information from an online focus group. The study compared the differences between general and special educators in regards to the motivating factors affecting the decision to become a teacher, remain a teacher, and in choosing a non-university-based ACP, as well as the perceived strengths and weaknesses of the ACP. The results from the survey suggest there are differences in the motivating factors affecting general and special educator's decision to become a teacher and to remain a teacher. Additional survey results suggest there are no differences in the reason these two groups chose a non-university-based ACP. The results of the survey and the online focus group were comparable for these two groups. The remainder of this dissertation includes a review of literature related to teacher shortages and teacher preparation including alternative certification. Additionally, information on the results and analysis of the study are discussed, as well as recommendations for future research.
Attenuation of the Squared Canonical Correlation Coefficient Under Varying Estimates of Score Reliability
Research pertaining to the distortion of the squared canonical correlation coefficient has traditionally been limited to the effects of sampling error and associated correction formulas. The purpose of this study was to compare the degree of attenuation of the squared canonical correlation coefficient under varying conditions of score reliability. Monte Carlo simulation methodology was used to fulfill the purpose of this study. Initially, data populations with various manipulated conditions were generated (N = 100,000). Subsequently, 500 random samples were drawn with replacement from each population, and data was subjected to canonical correlation analyses. The canonical correlation results were then analyzed using descriptive statistics and an ANOVA design to determine under which condition(s) the squared canonical correlation coefficient was most attenuated when compared to population Rc2 values. This information was analyzed and used to determine what effect, if any, the different conditions considered in this study had on Rc2. The results from this Monte Carlo investigation clearly illustrated the importance of score reliability when interpreting study results. As evidenced by the outcomes presented, the more measurement error (lower reliability) present in the variables included in an analysis, the more attenuation experienced by the effect size(s) produced in the analysis, in this case Rc2. These results also demonstrated the role between and within set correlation, variable set size, and sample size played in the attenuation levels of the squared canonical correlation coefficient.
Educators' Perceptions of the Importance of Selected Competencies for Teachers of Students with Emotional and Behavioral Disorders and their Perceptions of Personal Proficiency
This study investigated educators' perceptions of the importance of competencies for teachers of students with emotional and behavioral disorders and their own proficiency in the competencies. Participants included educators who had completed university-based coursework on emotional and behavioral disorders. Competencies from the Qualification and Preparation of Teachers of Exceptional Children study were correlated with CEC's content standards and knowledge skill sets for special education teachers of individuals with emotional and behavioral disorders. Participants ranked 88 competencies on importance and proficiency. Results revealed that educators' proficiency in competencies, their years of experience, and level of education contribute a significant percentage of variance in their ratings of the importance of competencies. Implications for further research are provided.
Effects of the Why Try Social Skills Program on Students with Emotional and Behavioral Disorders at an Alternative Campus
Approximately 20% of students with emotional and behavioral disorders (E/BD) are sent to an alternative campus for their lack of social competence. Social skills training (SST) is an evidence-based intervention to help increase social competence for students with E/BD, but there is limited research that addresses SST for students with E/BD at alternative campuses. A mixed-methods design was utilized to examine SST at an alternative campus for students with E/BD. Pre-intervention data were collected for students' attendance, grades, office disciplinary referrals, and behavioral rating scales, after which, the Why Try SST program was implemented. Following the intervention, the same type of data were collected. Nonparametric statistics guided the quantitative analysis, because of the small population being studied. Differences from pre- to post-intervention were examined. Triangulation methods drove the qualitative data collection and analysis through observations, student interviews, and teacher interviews. Students exhibited significant differences from pre- to post-intervention in the number of office disciplinary referrals and several areas on the behavioral rating scales. Important insight into motivation and perceptions was gained through the observations and interviews.
A Hierarchical Regression Analysis of the Relationship Between Blog Reading, Online Political Activity, and Voting During the 2008 Presidential Campaign
The advent of the Internet has increased access to information and impacted many aspects of life, including politics. The present study utilized Pew Internet & American Life survey data from the November 2008 presidential election time period to investigate the degree to which political blog reading predicted online political discussion, online political participation, whether or not a person voted, and voting choice, over and above the predication that could be explained by demographic measures of age, education level, gender, income, marital status, race/ethnicity, and region. Ordinary least squares hierarchical regression revealed that political blog reading was positively and statistically significantly related to online political discussion and online political participation. Hierarchical logistic regression analysis indicated that the odds of a political blog reader voting were 1.98 the odds of a nonreader voting, but vote choice was not predicted by reading political blogs. These results are interpreted within the uses and gratifications framework and the understanding that blogs add an interpersonal communication aspect to a mass medium. As more people use blogs and the nature of the blog-reading audience shifts, continuing to track and describe the blog audience with valid measures will be important for researchers and practitioners alike. Subsequent potential effects of political blog reading on engagement, discussion, and participation will be important to understand as these effects could impact the political landscape of this country and, therefore, the world.
Knowledge and Confidence of Speech-Language Pathologists Regarding Autism
The increased prevalence rate of autism has immense implications for speech language pathologists (SLPs) who are directly involved in the education and service delivery for students with autism. However, few studies have documented the effectiveness of the knowledge and confidence of SLPs regarding autism. The purpose of this study was to measure the knowledge and confidence of SLPs regarding autism and the extent to which their educational and professional training prepared them to work effectively with this population. An online survey was administered to and returned by 336 SLPs nation-wide. Two multiple linear regressions were conducted to determine the variables that explained overall knowledge and confidence. The number of students with autism on one's caseload explained most of the variance. Independent sample t-test results depicted knowledge and confidence scores of SLPs who were behaviorally trained versus those who were not behaviorally trained. SLPs who were behaviorally trained had higher mean scores on measures of knowledge and confidence when compared to those without formal behavioral training. Finally, a bivariate correlation was conducted to explore the relationship between knowledge and confidence of SLPs, however, results were not statistically significant.
Knowledge and Training in Autism Spectrum Disorders Among Special Education Administrators.
A significant rise in the number of students with autism spectrum disorders (ASD) served in today's schools requires special education administrators to possess knowledge in this area. The purpose of this study was to determine the general knowledge of special education administrators concerning ASD and knowledge of educational programming, to explore their educational training and professional development experiences in ASD, to identify the training needs of special education administrators in ASD, and to determine if knowledge, training and experience in ASD predict litigation. Using survey methods, data were collected from a sample of 106 special education administrators in Texas. Data revealed special education administrators were most knowledgeable of general characteristics, common myths, and instructional strategies, and less knowledgeable of eligibility criteria. Knowledge regarding educational programming for learners with ASD produced mixed results. Logistic regression analysis revealed general autism knowledge, knowledge of educational programming, training, and experience in ASD were not factors predicting litigation. Although results indicated none of the factors explored in this study were predictors of litigation, areas of need regarding professional development were identified. Implications for future research are also discussed.
Spatial Ability, Motivation, and Attitude of Students as Related to Science Achievement
Understanding student achievement in science is important as there is an increasing reliance of the U.S. economy on math, science, and technology-related fields despite the declining number of youth seeking college degrees and careers in math and science. A series of structural equation models were tested using the scores from a statewide science exam for 276 students from a suburban north Texas public school district at the end of their 5th grade year and the latent variables of spatial ability, motivation to learn science and science-related attitude. Spatial ability was tested as a mediating variable on motivation and attitude; however, while spatial ability had statistically significant regression coefficients with motivation and attitude, spatial ability was found to be the sole statistically significant predictor of science achievement for these students explaining 23.1% of the variance in science scores.
Structural Validity and Item Functioning of the LoTi Digital-Age Survey.
The present study examined the structural construct validity of the LoTi Digital-Age Survey, a measure of teacher instructional practices with technology in the classroom. Teacher responses (N = 2840) from across the United States were used to assess factor structure of the instrument using both exploratory and confirmatory analyses. Parallel analysis suggests retaining a five-factor solution compared to the MAP test that suggests retaining a three-factor solution. Both analyses (EFA and CFA) indicate that changes need to be made to the current factor structure of the survey. The last two factors were composed of items that did not cover or accurately measure the content of the latent trait. Problematic items, such as items with crossloadings, were discussed. Suggestions were provided to improve the factor structure, items, and scale of the survey.
Teachers' Perspectives on Student Problematic Behavior and Social Skills
The research investigation reported herein examined program outcomes of student problem behavior and social skills, based on teachers' perspectives, before and after early behavioral intervention services. The study targets students in kindergarten through grade five who are identified by the school system for being at-risk for being labeled with emotional and behavioral disorders. Students identified received early intervention services based on individualized positive behavioral supports (i.e., social skills training, functional behavioral assessment, and team collaboration). Teachers completed a teacher form of the Social Skills Rating System before and after the student received program services to determine differences in social skills and problematic behavior pre- and post- program early intervention services. An analysis was also made of the differences among gender, ethnicity, and grade according to the teachers' perspectives. Data indicated statistically significant results in the area of social skills and problem behavior. The results indicate early intervention services that teach social skills and use functional behavioral assessments to deal with problem behavior are beneficial to children displaying behavior challenges.
The Home Instruction for Parents of Preschool Youngsters (HIPPY) Program’s Effect on Academic Achievement of TAKS Tests
This study investigated the effectiveness of the Home Instruction for Parents of Preschool Youngsters (HIPPY) program on school readiness. The HIPPY program uses home-based instruction to aid parents in teaching their children school readiness skills. The curriculum in this program includes literacy, math, and social skills. Texas Assessment of Knowledge and Skills assesses the academic achievement of students in different grade levels and in various subject areas. The chi square test revealed that the children in the HIPPY program were more likely to have higher passing rates on the first administration of TAKS Reading, Math and Science sections compared to non-participants. The implementation of early intervention and parental involvement programs such as HIPPY helps to facilitate students‟ success.
Missing Data Treatments at the Second Level of Hierarchical Linear Models
The current study evaluated the performance of traditional versus modern MDTs in the estimation of fixed-effects and variance components for data missing at the second level of an hierarchical linear model (HLM) model across 24 different study conditions. Variables manipulated in the analysis included, (a) number of Level-2 variables with missing data, (b) percentage of missing data, and (c) Level-2 sample size. Listwise deletion outperformed all other methods across all study conditions in the estimation of both fixed-effects and variance components. The model-based procedures evaluated, EM and MI, outperformed the other traditional MDTs, mean and group mean substitution, in the estimation of the variance components, outperforming mean substitution in the estimation of the fixed-effects as well. Group mean substitution performed well in the estimation of the fixed-effects, but poorly in the estimation of the variance components. Data in the current study were modeled as missing completely at random (MCAR). Further research is suggested to compare the performance of model-based versus traditional MDTs, specifically listwise deletion, when data are missing at random (MAR), a condition that is more likely to occur in practical research settings.
Parent Involvement and Science Achievement: A Latent Growth Curve Analysis
This study examined science achievement growth across elementary and middle school and parent school involvement using the Early Childhood Longitudinal Study – Kindergarten Class of 1998 – 1999 (ECLS-K). The ECLS-K is a nationally representative kindergarten cohort of students from public and private schools who attended full-day or half-day kindergarten class in 1998 – 1999. The present study’s sample (N = 8,070) was based on students that had a sampling weight available from the public-use data file. Students were assessed in science achievement at third, fifth, and eighth grades and parents of the students were surveyed at the same time points. Analyses using latent growth curve modeling with time invariant and varying covariates in an SEM framework revealed a positive relationship between science achievement and parent involvement at eighth grade. Furthermore, there were gender and racial/ethnic differences in parents’ school involvement as a predictor of science achievement. Findings indicated that students with lower initial science achievement scores had a faster rate of growth across time. The achievement gap between low and high achievers in earth, space and life sciences lessened from elementary to middle school. Parents’ involvement with school usually tapers off after elementary school, but due to parent school involvement being a significant predictor of eighth grade science achievement, later school involvement may need to be supported and better implemented in secondary schooling.
Personnel Preparation in Special Education: An Exploration of Autism Spectrum Disorders Programmatic Changes in Institutions of Higher Education Teacher Training Programs
Programmatic change related to autism spectrum disorders (ASD) training in special education teacher education programs across the U.S. and institutional variables that influenced change were examined. Variables included institutions’ current coverage of autism content in coursework and institution enrollment. One faculty member from each identified institution was invited to participate in the study. Data were collected from 136 special education faculty using an exploratory survey instrument, the National Survey on ASD Preparation in Undergraduate Special Education Teacher Training Programs (NSAP). This study was designed around themes which emerged from empirical and pragmatic research findings conceptualizing prevalent issues in personnel preparation for ASD including critical knowledge and skills needed by teachers to effectively serve students with ASD. Results indicated a significant number of programmatic changes (66%) remain to be implemented in undergraduate special education programs at institutions participating in the study.
The Roles Elementary School Counselors Perform in the Education of Students with Autism Spectrum Disorders
This nation-wide study investigated elementary school counselors (ESC) self-reported: (a) professional background and training; (b) general knowledge of autism spectrum disorders (ASD); (c) attitudes towards ASD; and (d) roles performed with students identified with ASD. Also investigated was the predictive relationships between professional background, training, knowledge, and attitudes on roles (counseling, consultation, curriculum, and coordination) performed with students identified with ASD. Descriptive statistics were utilized to address professional background, training, knowledge, attitude and characteristics of ESC participants. These variables were also examined in relationship to the four role types. Multivariate analyses of variance (MANOVA) and Pearson’s correlation coefficients were used to test for significant relationships. A series of four multiple regression analyses predicting each of the total roles scores for counseling, consultation, curriculum, and coordination were also conducted. Results of the study suggest (a) ESC have limited training experiences of ASD, leading to self-education about this population of students, (b) ESC possess general knowledge about ASD, (c) overall, ESC have positive attitudes towards ASD, and (d) ESC perform all conceptualized roles in the education of students with ASD. Regression models revealed eight predictors found to influence roles: total knowledge, attitudes, geographic setting, U.S. region, years practiced, conference training, self-education, and ASD caseload. Significantly associated with performing roles across all four domains was the number of students with ASD on ESC caseload.
The Use of Evidence-based Practices in the Provision of Social Skills Training for Students with Autism Spectrum Disorders: a National Survey of School Psychologists' Training, Attitudes, and Practices
The purpose of this exploratory study was to examine school psychologists' use of evidence- based practices (EBP), in general, and more specifically in the area of social skills training (SST) for students with autism spectrum disorders (ASD). Study participants, consisting of 498 school psychologists from across the nation, participated in an online survey that gathered information about their training, attitudes, and practices. The frequency with which specific EBP practices for social skills training for students with ASD was examined, as was prediction of use of these practices. Multiple-regression analyses revealed multiple independent variables that were predictors for overall use of EBP. Results indicated that over half of the participants provide SST for students with ASD. Although the majority of participants indicated that their graduate program included at least one course with information about ASD and EBP practices, in general, nearly half indicated that their coursework did not include any courses that directly addressed social skills training for students with ASD. Confirmatory factor analysis (CFA) was used to determine the extent to which the data fit the factor model. Participants' perception of the importance placed on EBP by their school district, scores on the openness subscale of the Evidence Based Practices Assessment Scale, perception of how well their graduate program prepared them in the EBP process, perception of whether they were adequately trained in the area of SST for students with ASD, and having a caseload evenly divided among settings were significant predictors of overall use of EBP.
The Use Of Effect Size Estimates To Evaluate Covariate Selection, Group Separation, And Sensitivity To Hidden Bias In Propensity Score Matching.
Covariate quality has been primarily theory driven in propensity score matching with a general adversity to the interpretation of group prediction. However, effect sizes are well supported in the literature and may help to inform the method. Specifically, I index can be used as a measure of effect size in logistic regression to evaluate group prediction. As such, simulation was used to create 35 conditions of I, initial bias and sample size to examine statistical differences in (a) post-matching bias reduction and (b) treatment effect sensitivity. The results of this study suggest these conditions do not explain statistical differences in percent bias reduction of treatment likelihood after matching. However, I and sample size do explain statistical differences in treatment effect sensitivity. Treatment effect sensitivity was lower when sample sizes and I increased. However, this relationship was mitigated within smaller sample sizes as I increased above I = .50.
The Effect of Naturalistic Behavior Strategies on the Quality of Social Interactions for Children with Autism
Autism is primarily a social disorder and deficits in social?orienting may be responsible for the failure of children with autism to initiate critical social behaviors. The purpose of this research was to improve the quality of social interactions of children with autism by implementing naturalistic behavior strategies intervention utilizing a multiple baseline design across four participants. Naturalistic behavior strategies comprised a comprehensive package of integrated components including: (a) intervention in the child’s natural environment; (b) child-initiated play activities ; (c) prompts to emit language; (d) shaping for all vocal approximations and (e) delivery of natural reinforcement with embedded social interactions to maintain learned behavior. In addition to intervention, generalization of child behaviors was assessed across untrained parents and/or caregivers in the same environment. Results indicated the effectiveness of naturalistic teaching strategies package in increasing (a) the frequency of vocal mands for all children, (b) the number of times that children initiated social engagement during manding, and (c) intervals of nonverbal dyadic orienting. These skills generalized across two untrained caregivers in the same clinical setting without any training from the interventionist. Two parents required training during the generalization phase in order for their child’s behaviors to maintain at levels demonstrated during the intervention phase. Implications for future research and clinical practice are discussed.
Service Provisions for Youth with Emotional and Behavioral Disorders
Youth with emotional or behavioral disorders (EBD) have poorer outcomes compared to their peers with and without disabilities. As a result, the federal government has mandated transition services to improve supports and ultimately student outcomes. Using data from the National Longitudinal Transition Study-2 (NLTS-2), this secondary analysis looked at services provided to youth with EBD (n = 410). The purpose of the study was to show a relationship between utilization of multiple services and the attainment of paid employment, and/or attending post-secondary education. Results indicate relationships between receiving financial services, tutoring and educational services and vocational services with attending a post-secondary institution. Logistic regression indicated a relationship between time, age and amount or services with paid employment. These results indicate the need for continuous, systematic and linked services for youth with EBD well into their twenties.
Teacher Educators: What Motivates Them to Choose Academe?
Currently, there is a shortage of professors preparing personnel to teach in high need areas (e.g., special education, English language learners) at institutions of higher education (IHE). The purpose of the present study was to examine the motivations or influencers that impelled individuals to pursue careers in IHEs as professors in personnel preparation. Data were collected using Motivations for Choosing Academia as a Profession (MCAP) and a 10-item Big Five Inventory (BFI-10). Two hundred eighty-nine professors of education representing the four U.S. census regions participated in the present study. The MCAP is a 25-item instrument designed to measure retrospective motivation of faculty decisions to enter the professoriate. The development of the MCAP is described and an exploratory factor analysis was employed to examine the psychometric validity of the instrument. Three factors emerged and implications are discussed. Data were analyzed using logistic regression with the dichotomous outcome variable being the area of education in which the professor works (i.e., general or special education).
Teacher Perceptions of Inclusionary Practices for Students with Emotional/behavioral Disorders
The present study examined variables affecting teachers’ perceptions of inclusionary practices for students with emotional and behavioral disorders (E/BD) in three areas: inclusion of students with E/BD, behaviors of students with E/BD, and teacher efficacy. Teachers listed in the database of one Education Service Center located in north central Texas which represented 66 school districts, completed the online Survey on Teacher Perceptions of Inclusionary Practices for Students with Emotional/Behavioral Disorders. Findings of the study showed that (a) teaching experience was a significant predictor of teacher’s perceptions regarding the inclusion of students with E/BD, (b) student age was a significant predictor of teachers’ perceptions regarding behaviors of students with E/BD, (c) special education teachers are more likely to have a higher degree of perceptions on the subscale that measures their efficacy than general education teachers, and (d) the number of special education courses taken by general education teachers did not have a significant effect on teachers’ perceptions.
Teachers of Students with Emotional and Behavioral Disorders’ Perceptions of Professional Standards of Practice
In recent decades, there has been renewed interest in examining the effectiveness of teacher preparation programs. Unfortunately, researchers have found that there is limited empirical research on the effectiveness of quality special education teacher preparation programs, specifically those programs specializing in the education of students with emotional and behavioral disorders (EBD). The Council for Exceptional Children (CEC), the largest special education organization, conducts research on the standards needed by teachers who serve children and youth with exceptionalities. These CEC standards are recommended to serve as a guide for teacher preparation programs in special education. Utilizing the CEC standards delineated for preparation programs in EBD, the present study sought to determine how graduates of one program perceived the importance of the standards and their perceived proficiency in using the standards in their work with students with EBD. Results indicated that graduates viewed the standards as Important to their work with students with EBD. Further, they viewed their proficiency in using the standards to be above average. In addition, the present study examined the relationship between graduates perceived importance and perceived proficiency in using the CEC standards. Results indicated that graduates who had higher score ratings on their perceived importance of the standards tended to have higher ratings on their perceived proficiency scores.
Convergent Validity of Variables Residualized By a Single Covariate: the Role of Correlated Error in Populations and Samples
This study examined the bias and precision of four residualized variable validity estimates (C0, C1, C2, C3) across a number of study conditions. Validity estimates that considered measurement error, correlations among error scores, and correlations between error scores and true scores (C3) performed the best, yielding no estimates that were practically significantly different than their respective population parameters, across study conditions. Validity estimates that considered measurement error and correlations among error scores (C2) did a good job in yielding unbiased, valid, and precise results. Only in a select number of study conditions were C2 estimates unable to be computed or produced results that had sufficient variance to affect interpretation of results. Validity estimates based on observed scores (C0) fared well in producing valid, precise, and unbiased results. Validity estimates based on observed scores that were only corrected for measurement error (C1) performed the worst. Not only did they not reliably produce estimates even when the level of modeled correlated error was low, C1 produced values higher than the theoretical limit of 1.0 across a number of study conditions. Estimates based on C1 also produced the greatest number of conditions that were practically significantly different than their population parameters.
Effects of a Prototypical Training Program on the Implementation of Systematic Observational Data Collection on Iep Objectives for the Core Deficits of Autism Spectrum Disorders
Legal mandates and best practice recommendations for the education of students with autism spectrum disorders (ASD) emphasize the importance of systematic, ongoing observational data collection in order to monitor progress and demonstrate accountability. The absence of such documentation in decision-making on instructional objectives indicates a weakness in bridging the research-to-practice gap in special education. Utilizing a multiple baseline design across participants, the current study evaluated the effects of a prototypical teacher training program (i.e., workshop, checklist, in-classroom training with feedback, and maintenance with a thinned schedule of feedback) on the frequency of data collection on core deficits of ASD and the use of data-based decision-making. Results indicate increases in daily mean frequency of data collection following intervention. Maintenance and generalization indicates variable responding across participants. Effect size (Cohen's d) indicates a large, clinically significant effect of the training program. Results are discussed in relation to training models, maintenance, and future research.
Educational Experiences of Youth with And/or At-risk for Emotional and Behavioral Disorders Residing in Foster Care Settings
Research examining the academic experiences of youth with emotional and behavioral disorders (EBD) residing in foster care (FC) is scarce. Research is warranted to understand the academic strengths, weaknesses, and school disciplinary experiences of youth with EBD residing in FC. Data from the National Survey of Child and Adolescent Well-being II (NSCAW II) included data on eight participants classified as EBD. Having a limited number of participants classified as EBD in the data set, I used participants’ scores on the Child Behavior Checklist (CBCL) to classify participants who may be at-risk for EBD. Analyses were conducted to determine if significant relationships existed between participants’ internalizing and externalizing scores on the CBCL and their (a) scores on assessments of academic achievement and (b) behavior problems leading to suspension or expulsion. Results indicated that participants’ scores on the CBCL were not predictive of their academic achievement or of their numbers of behavior problems leading to suspension or expulsion.
Examination of Contributing Factors for Successful Postsecondary Transitions to Institutions of Higher Education for Youth with High-incidence Disabilities
Transitions are a natural part of life. Youth grow and develop physically, socially, psychologically, and intellectually during primary and secondary school years. The transition from secondary to postsecondary education is an important transition as youth not only move from high school to college, but also from adolescence to young adulthood. It is a time when young adults naturally desire to become more independent in pursuit of their personal dreams and aspirations. The purpose of this study was to examine the impact that academic, psychological, and social factors on youth with high-incidence disabilities as they strive to make successful postsecondary education transitions. Current trends indicate youth with high-incidence disabilities are graduating from high school and are attending vocational schools, colleges, and universities in increasing numbers. Transition barriers still limit many youth who could otherwise attend institutions of higher education regardless of disability type. Findings suggest academic and psychological factors most significantly predict successful postsecondary education transitions. Recommendations for improved transition planning and parental training are suggested.
Is It More Advantageous to Administer Libqual+® Lite Over Libqual+®? an Analysis of Confidence Intervals, Root Mean Square Errors, and Bias
The Association of Research Libraries (ARL) provides an option for librarians to administer a combination of LibQUAL+® and LibQUAL+® Lite to measure users' perceptions of library service quality. LibQUAL+® Lite is a shorter version of LibQUAL+® that uses planned missing data in its design. The present study investigates the loss of information in commonly administered proportions of LibQUAL+® and LibQUAL+® Lite when compared to administering LibQUAL+® alone. Data from previous administrations of LibQUAL+® protocol (2005, N = 525; 2007, N = 3,261; and 2009, N = 2,103) were used to create simulated datasets representing various proportions of LibQUAL+® versus LibQUAL+® Lite administration (0.2:0.8, 0.4:0.6. 0.5:0.5, 0.6:0.4, and 0.8:0.2). Statistics (i.e., means, adequacy and superiority gaps, standard deviations, Pearson product-moment correlation coefficients, and polychoric correlation coefficients) from simulated and real data were compared. Confidence intervals captured the original values. Root mean square errors and absolute and relative biases of correlations showed that accuracy in the estimates decreased with increase in percentage of planned missing data. The recommendation is to avoid using combinations with more than 20% planned missing data.
Preschool Teachers' Self-reported Levels of Preparation for Classroom Behavior Management
Research indicates that serious behavior problems begin during the early childhood years. The study examined the perceived preparedness of teachers related to behavior management as well as preschool teachers' usage of evidence-based prevention and intervention strategies. The data indicates that preschool teachers feel prepared for managing aggression in their classrooms and report utilizing evidence-based prevention and intervention strategies regularly. Additionally, the data shows a weak relationship between teacher variables and the likelihood of feeling prepared for managing aggression or utilizing evidence-based strategies. The results can be used to gain a better understanding of special education preschool teachers' training needs in regard to behavior management and managing behavior problems in the preschool classroom.
The Extent of Autism Knowledge of Novice Alternatively Certified Special Education Teachers in Texas
An increase in the prevalence rate of autism is not necessarily matched by a concurrent increase in the rate of highly qualified special education teachers. The low ratio of highly qualified teachers to the number of students with autism has resulted in chronic teacher shortages in this area. Alternative certification is used as a mechanism to alleviate the demand for highly qualified teachers in special education. However, alternative certification routes have often left novice teachers underprepared for teaching students with autism, more specifically in the implementation of evidence-based practices necessary for instructional effectiveness. The purposes of the study were: a) to assess the knowledge of novice alternatively certified (AC) teachers in the area of autism education; and b) to determine the extent to which age, credit hours of instruction, formal hours of instruction, amount of professional development, and number of students with autism predict the variance in knowledge scores. Participants included all novice (i.e., first-and second-year) alternatively certified special education teachers in the state of Texas. Data were collected through an electronic survey instrument disseminated state-wide to approximately 33 individuals. Multiple regression was conducted in order to determine the strongest predictors of autism knowledge scores. In addition, a multi-way ANOVA was performed to identify differences between groups. The largest predictor of knowledge of autism was hours engaged in self-directed learning. Overall, AC programs in Texas need to provide basic and core content in the area of autism to increase the knowledge of novice teachers.
Mexican Mothers’ Experiences with Depression, Intimate Partner Violence, and Immigration: a Mixed Methods Study of Maternal Self-efficacy
This study investigated the relation between maternal self-efficacy, depression, and intimate partner violence among Mexican immigrant and Mexican mothers. The research was conducted using a parallel mixed methods approach including both qualitative and quantitative methods. A total of 136 mothers living in the United States and Mexico completed surveys, and 10 mothers participated in semi-structured interviews. In a regression on maternal depression, living in Mexico as opposed to the U.S., psychological violence, and maternal self-efficacy were significant predictors of maternal depression. In the qualitative data analysis, we found five main themes: perceptions, cultural influence, involvement, resources, and barriers. In this stage of the study, Mexican and Mexican immigrant mothers described in detail their experiences of being a mother, their perceptions of maternal self-efficacy, and the influence of intimate partner violence and depression on their effectiveness as mothers. Overall, Mexican immigrant families appeared to have healthier relationships and greater well-being than Mexican families.
The Use of a Stimulus Control Transfer Procedure to Teach Spontaneous Manding to Children with Autism
Current research indicates that the inability to spontaneously communicate needs or wants may result in the acquisition of unconventional forms of requesting such as aggression and tantrums. This in turn limits the amount of access that students with autism have to neurotypical peers and social environments. The purpose of this study was to investigate the effect of using a stimulus control transfer procedure on the acquisition of spontaneous mands. Four school-aged children with autism, two boys and two girls, participated in the study. A multiple baseline design across participants was utilized to demonstrate a functional relation between the stimulus control transfer procedures and the rate of spontaneous mands. Measurement variables included the frequency of spontaneous versus multiply-controlled mands during discrete trial training on a variety of verbal operants. Effectiveness of the intervention was analyzed through visual analysis and the magnitude of effect was assessed through effect size. Visual analysis indicated that three of the four participants learned to spontaneously mand for items out of view and demonstrated generalization across targets, staff and environments. The effect size for three participants were large (d = 1.94; d = 2.2; and d = 1.4), whereas the outcome of intervention for one participant (d = 0.98) indicated moderate effect. The overall (d = 1.15) outcome demonstrated a large effect of the intervention on the rate of mands. Based on the results of this study, it is recommended that early and intensive behavior intervention programs for children with autism incorporate this type of procedure for socially significant outcomes.
Eastern Work Ethic: Structural Validity, Measurement Invariance, and Generational Differences
This present study examined the structural validity of a Chinese version of Multidimensional Work Ethic Profile (MWEP-C), using a large sample of Chinese parents and their young adult children (N = 1047). Confirmatory factor analysis (CFA) was applied to evaluate the model fit of sample data on three competing models using two randomly split stratified subsamples. Measurement invariance for these two generational respondents was checked using differential item functioning (DIF) analysis. The results indicated that MWEP-C provided a reasonable fit for the sample data and the majority of survey items produced similar item-level responses for individuals that do not differ on the attributes of work ethic across these two generations. DIF items were detected based on advanced and successive iterations. Monte Carlo simulations were also conducted for creating threshold values and for chi-square probabilities based on 1,000 replications. After identifying the DIF items, model fit improved and generational differences and similarities in work ethic between parents and their young adult children were also identified. The results suggested that the younger Chinese generations have higher work ethic mean scores on the dimensions of work centrality and morality/ethics while they have similarities on time concept, self-reliance, delay of gratification, and hard work as their parents.
The Impact of Teacher Perception of Cultural Competence on the Instructional Decision Making of English As Second Language (ESL) Students
Recent research suggests that culturally responsive teaching (CRT) practices have the potential to increase student educational outcomes, as well as to reduce unnecessary or inappropriate placement referrals. Examination of the core components in CRT, teacher efficacy and cultural competence, is proposed to be a critical step to reduce unwarranted referrals of culturally and linguistically diverse students. However, there is limited empirical support for the relationship between CRT and instructional referrals, and even among existing studies there is inconsistency regarding the relation of these constructs. The purpose of this study is to examine teacher factors (i.e., teacher role, degree earned, years of teaching, ESL certification held, language proficiency and ethnicity) as a predictor of teacher competence, and the role these factors play in teachers’ referral decision making. To investigate these relationships, a national sample of elementary teachers (N = 258) completed a survey addressing their background, profession endorsements, sense of teaching efficiency, and the instructional decisions they would make in the scenarios presented. The results of this study revealed that teacher role (i.e., general, ESL or special educator) and ESL certification were important predictors of teacher competency. A statistically significant mean difference in teacher competency was found between teachers with and without ESL certification, indicating ESL certification as an important factor in deciding the level of teacher competency. Finally, teacher competency was found to improve teachers’ instructional decision making in scenarios in which the students displayed linguistic difficulties. The findings provide valuable insights to teacher training programs and other professional development entities regarding how to prepare educators to work more efficiently with ESL students.
Perceptions of Family Vacation and Family Cohesion and the Moderating Effects of Parenting Style
Family cohesion, or emotional bonding, is important to family functioning. Shared activities such as family vacations offer opportunities for strengthening the family unit which can improve cohesion. Additionally, parenting style has direct influence on the family unit and family cohesion. This study’s purpose was to assess to what extent the perception of the family vacation experience predicted the perception of family cohesion and whether that relationship was moderated by parenting style. An online survey was conducted, resulting in 97 adult participants responding to items regarding their last family vacation, family cohesion, and parenting style. Using hierarchical multiple regression, a medium effect size was found for the predictive ability of a participant’s perception of their last family vacation on family cohesion. Findings also indicated a negative correlation between an authoritarian parenting style and perception of family cohesion, but a positive relationship between the interaction of family vacation experience and authoritarian parenting to family cohesion. Stronger predictive abilities were found for those with children in the 3-11 age group. Results may encourage parent and family educators to use family vacation as a tool in assisting families with the processes of building strong and cohesive families.
Spatial Ability in Registered Nurses
Spatial ability is the skill associated with mental relations among objects, the process of maintaining the physical aspects of an object after mentally rotating it in space. Many studies report a strong association of spatial ability with success in various areas of health care, especially surgery, radiology and dentistry. To date, similar investigations in professional nursing could not be located. Registered nurses, employed in an acute care multi-hospital setting, were surveyed using the Shipley-2Block Pattern Test, the Group Embedded Figures Test, and a newly created test of general nursing knowledge. The sample size of 123 nurses was composed of 31 male nurses and 92 female nurses. Data was collected between May and August of 2013 and analyzed using R, version 2.15.2. The present study did not demonstrate a statistically significant effect for gender differences on two measures of spatial ability. However, Cohen’s d effect sizes for mean gender differences in the present study are consistent with prior studies. This may suggest the nursing profession is comparable with other professions where males perform higher than females on spatial ability. The present study should be considered an initial step toward evaluating the relevance of spatial ability in the performance of nursing care.
A Study of Novice Special Education Teachers’ Preparation to Teach Students with Autism Spectrum Disorders
The purpose of this study is to identify novice teachers’ perception of their preparedness to teach a class designed for students with autism spectrum disorder (ASD) after graduation from a traditional university-based special education program or from a special education alternative certification program. Teacher preparedness and the need for highly qualified teachers of students with ASD are relevant topics, as the prevalence rate of ASD continues to increase. This phenomenological qualitative study explores novice teachers’ perceptions of preparedness to teach students with ASD and their knowledge about teaching students with ASD. Semi-structured, in-depth interviews were conducted with six novice special education teachers of students with ASD. Results indicated that novice teachers of students with ASD have knowledge of autism and evidence-based practices (EBP), which they ascertained primarily through experiences such as; working directly with students with ASD, however, preservice education programs provided the participants with cursory information related to knowledge of ASD and EBP.
Construct Validation of the Social-Emotional Character Development Scale in Belize: Measurement Invariance Through Exploratory Structural Equation Modeling
Social-emotional learning (SEL) measures assessing social-emotional learning and character development across a broad array of constructs have been developed but lack construct validity. Determining the efficacy of educational interventions requires structurally valid measures which are generalizable across settings, gender, and time. Utilizing recent factor analytic methods, the present study extends validity literature for SEL measures by investigating the structural validity and generalizability of the Social-Emotional and Character Development Scale (SECDS) with a large sample of children from schools in Belize (n = 1877, ages 8 to13). The SECDS exhibited structural and generalizability evidence of construct validity when examined under exploratory structural equation modeling (ESEM). While a higher order confirmatory factor structure with six secondary factors provided acceptable fit, the ESEM six-factor structure provided both substantive and methodological advantages. The ESEM structural model situates the SECDS into the larger body of SEL literature while also exhibiting generalizability evidence over both gender and time.
Criterion Validity of Common Career Interest Inventories: Relative Efficacy with High School Seniors
Professional school counselors frequently use career interest inventories as part of a comprehensive guidance program to help students create a post-secondary school plan. The present study evaluates the validity of three commonly used interest inventories, the Myers-Briggs Type Indicator, Self-Directed Search, and Strong Interest Inventory on field of study choice for graduating high school seniors (N = 616) from a large, suburban high school in Texas. Students identified their intended postsecondary field of study category, were randomly assigned using stratification to three groups, and each group completed a different inventory. Group membership was evaluated to establish covariate balance on a wide variety of indicators. Data from each group was evaluated to determine the extent to which the inventory predicted the chosen field of study, as well as Other and Undeclared categories using logistic regression models. None of the inventory models suggest that the inventory accurately predicts Other or Undeclared outcomes. For students selecting intended postsecondary fields of study, the Self Directed Search predicts such outcomes better than other measures. Professional school and career counselors should consider the SDS in addition to narrative counseling strategies to add greater precision with career decision making among clients and students.
The Effect of Co-teaching on the Academic Achievement Outcomes of Students with Disabilities: a Meta-analytic Synthesis
Co-teaching has been, and continues to be, a growing trend in American schools since the late 1990s. As the popularity of this service delivery model increases, there is an imperative need for empirical research focusing on how co-teaching affects academic outcomes of students who receive special education services. Evidence regarding the academic outcomes of co-teaching is limited, and reports mixed results. The purpose of this study is to provide a synthesis of research examining academic outcomes of co-teaching on students who receive special education services. Quantitative information from each research report was coded, an overall effect size was computed, and a moderator analysis was conducted. Results suggest a significant effect (g = .281, k = 32, p < .05) of co-teaching on the academic outcomes of students with disabilities when compared to students with disabilities who did not receive instruction in co-taught settings; though a larger effect was found among dissertation reports (g = .439, k = 25, p < .001). Additionally, a significant effect was found when examining the academic outcomes of students in co-teaching compared to the academic outcomes of students in a resource classroom setting (g = .435, k = 27, p < .001. Lastly, effects were stronger the longer these students were in co-teaching environments. Implications of findings and recommendations for further research are discussed.
The Impact of HIPPY on Maternal Self-Efficacy
Parenting self-efficacy refers to the ability of parents to have confidence in their abilities to effectively parent their children. Parenting self-efficacy can be divided into two types: (a) general parenting self-efficacy, which is defined as a parent’s overall sense of ability to effectively parent; and (b) task-specific parenting self-efficacy, which is defined as a parent’s confidence level to perform specific parenting tasks, such as teaching and nurturing (tested in this study). The study applied Bronfenbrenner’s bioecological theory to an analysis of (a) the effect of the HIPPY program in interaction with family and neighborhood variables on parenting self-efficacy and (b) the effect of the interaction of family and neighborhood variables on parenting self-efficacy. A group of 138 HIPPY mothers and a group of 76 comparison mothers who did not receive HIPPY services were surveyed. The sample was largely Hispanic. Results indicated HIPPY predicts task-specific parenting self-efficacy for teaching tasks, but not general parenting self-efficacy or task-specific efficacy for nurturance. Many family variables that reflected Hispanic family values were unique predictors of all three types of parenting self-efficacy, both in analyses involving interactions with HIPPY and with neighborhood variables. Neighborhood variables solely predicted general parenting self-efficacy. Moderation effects were found for the interaction between family conflict and neighborhoods in predicting general parenting self-efficacy, and the interactions between family control and all three types of parenting self-efficacy. Overall, the bioecological model was inapplicable to urban, Hispanic mothers in the surveyed population because of the lack of interaction effects found in the study.
Resilience Among Graduates From Alternative Education Programs
Research has shown that students with emotional and behavioral disorders (EBD) typically have poor life outcomes. Students with EBD who are placed in an alternative education setting are likely to continue a path toward failure without carefully designed effective services. Existing studies have independently examined resilience in children and youth and alternative education settings. However, there is a gap in research examining resilience in students who have graduated from alternative education settings. Using semi-structured interviews, the present interpretive and descriptive qualitative study sought to explore factors of resilience in individuals who graduated from alternative education settings. The study sought to identify elements, specific to alternative education settings, that have contributed to resilience in young adulthood and to further our understanding of how alternative education placements have contributed to the participants’ current life status. Findings revealed three themes specific to alternative education settings that contributed to participants’ resilience: teachers who show that they care about their students, a positive learning environment, and a small student-teacher ratio where participants were able to get more one-on-one instruction. Additionally, two other themes arose from the data: having a supportive family and an innate sense of self.
A Structural and Psychometric Evaluation of a Situational Judgment Test: The Workplace Skills Survey
Some basic but desirable employability skills are antecedents of job performance. The Workplace Skills Survey (WSS) is a 48-item situational judgment test (SJT) used to assess non-technical workplace skills for both entry-level and experienced workers. Unfortunately, the psychometric evidence for use of its scores is far from adequate. The purpose of current study was two-fold: (a) to examine the proposed structure of WSS scores using confirmatory factor analysis (CFA), and (b) to explore the WSS item functioning and performance using item response theory (IRT). A sample of 1,018 Jamaican unattached youth completed the WSS instrument as part of a longitudinal study on the efficacy of a youth development program in Jamaica. Three CFA models were tested for the construct validity of WSS scores. Parameter estimations of item difficulty, item discrimination, and examinee’s proficiency estimations were obtained with item response theory (IRT) and plotted in item characteristics curves (ICCs) and item information curves (IICs). Results showed that the WSS performed quite well as a whole and provided precise measurement especially for respondents at latent trait levels of -0.5 and +1.5. However, some modifications of some items were recommended. CFA analyses showed supportive evidence of the one-factor construct model, while the six-factor model and higher-order model were not achieved. Several directions for future research are suggested.
Computer Assisted Instruction to Improve Theory of Mind in Children with Autism
Children with autism spectrum disorder (ASD) show significant deficits in communication, emotion recognition, perspective taking, and social skills. One intervention gaining increased attention is the use of computer assisted instruction (CAI) to teach social, emotional and perspective-taking skills to individuals with ASD with the purpose of improving theory of mind skills. This study evaluated the effectiveness of CAI for improving theory of mind skills in four children with high functioning autism ages 5 to 12 years. A single-subject multiple baseline research design across participants was utilized to evaluate the effectiveness of CAI. The software contained 22 instructional scenarios that asked participants to identify emotions of characters based on situational cues displayed in line drawn pictures and audio feedback for correct and incorrect responses. Mind-reading skills were assessed using ten randomly selected scenarios for various emotions and no audio feedback. Visual analysis of the data revealed that all four participants increased mind-reading skills during the CAI condition. Additionally, this study evaluated levels of task engagement during experimental conditions. Three of the four participants showed an increase in task engagement during CAI compared to paper-based social stories used during baseline. Generalization of skills was assessed through the use of social scenarios acted out by family members of participants. All four participants were able to correctly identify emotions displayed in generalization scenarios. Results demonstrated that CAI was an effective and socially viable method for improving ToM skills in children with autism and they could generalize their skills to untrained settings.
A Performance Evaluation of Confidence Intervals for Ordinal Coefficient Alpha
Ordinal coefficient alpha is a newly derived non-parametric reliability estimate. As with any point estimate, ordinal coefficient alpha is merely an estimate of a population parameter and tends to vary from sample to sample. Researchers report the confidence interval to provide readers with the amount of precision obtained. Several methods with differing computational approaches exist for confidence interval estimation for alpha, including the Fisher, Feldt, Bonner, and Hakstian and Whalen (HW) techniques. Overall, coverage rates for the various methods were unacceptably low with the Fisher method as the highest performer at 62%. Because of the poor performance across all four confidence interval methods, a need exists to develop a method which works well for ordinal coefficient alpha.
Parenting Style, Frequency of Electronic Communication with Parents, and the Development of Independence in First Year, First Semester College Students
During the transition to college, emerging adults are expected to develop independence and increase individual responsibility as they live away from home for the first time. Modern electronic communication has enabled emerging adults to maintain frequent, daily contact with the parent, a pattern of communication Hofer refers to as an “electronic tether.” This study examined the link between parenting style and the development of independence of first year, first semester college students. Although these students were in frequent contact with their designated parent, no correlation between frequency of communication and parenting style or independence was found. Both authoritative and helicopter parenting significantly positively predicted attitudinal independence. However, permissive parenting functioned as a significant negative predictor. Authoritarian, permissive, and helicopter parenting significantly positively predicted conflictual independence. However, authoritative parenting functioned as a significant negative predictor. Both authoritative and helicopter parenting significantly positively predicted emotional and functional independence.
Time Series Data Analysis of Single Subject Experimental Designs Using Bayesian Estimation
This study presents a set of data analysis approaches for single subject designs (SSDs). The primary purpose is to establish a series of statistical models to supplement visual analysis in single subject research using Bayesian estimation. Linear modeling approach has been used to study level and trend changes. I propose an alternate approach that treats the phase change-point between the baseline and intervention conditions as an unknown parameter. Similar to some existing approaches, the models take into account changes in slopes and intercepts in the presence of serial dependency. The Bayesian procedure used to estimate the parameters and analyze the data is described. Researchers use a variety of statistical analysis methods to analyze different single subject research designs. This dissertation presents a series of statistical models to model data from various conditions: the baseline phase, A-B design, A-B-A-B design, multiple baseline design, alternating treatments design, and changing criterion design. The change-point evaluation method can provide additional confirmation of causal effect of the treatment on target behavior. Software codes are provided as supplemental materials in the appendices. The applicability for the analyses is demonstrated using five examples from the SSD literature.
Traditional Bullying and Cyberbullying in Korean Children and Youth with Emotional and Behavioral Disabilities: Examination of Contributing Factors
Children and Adolescents with emotional and behavioral disabilities (EBD) are often involved in aggression, acting out, bullying, violence, substance abuse, and juvenile crime. However, the limited Korean studies have focused primarily on bullying of students with developmental disabilities or intellectual disabilities. Therefore, the current study aimed to explore contributing factors to traditional bullying and cyberbullying in Korean children and adolescents with EBD. The current study surveyed 112 students with EBD between ages of 10 and 15 and their parents (guardians). The results revealed that internalizing problem behaviors including anxious/depression, withdrawal/depression, and somatic problems significantly affected traditional bullying victimization of Korean students with EBD. The peer support was a significant factor affecting cyberbullying victimization. Furthermore, the maternal psychological control was a meaningful factor affecting perpetration at school and in cyber world. Based on the findings, the present study described implications regarding prevention and intervention programs for addressing traditional bullying and cyberbullying victimization and perpetration.
Comparing Three Effect Sizes for Latent Class Analysis
Traditional latent class analysis (LCA) considers entropy R2 as the only measure of effect size. However, entropy may not always be reliable, a low boundary is not agreed upon, and good separation is limited to values of greater than .80. As applications of LCA grow in popularity, it is imperative to use additional sources to quantify LCA classification accuracy. Greater classification accuracy helps to ensure that the profile of the latent classes reflect the profile of the true underlying subgroups. This Monte Carlo study compared the quantification of classification accuracy and confidence intervals of three effect sizes, entropy R2, I-index, and Cohen’s d. Study conditions included total sample size, number of dichotomous indicators, latent class membership probabilities (γ), conditional item-response probabilities (ρ), variance ratio, sample size ratio, and distribution types for a 2-class model. Overall, entropy R2 and I-index showed the best accuracy and standard error, along with the smallest confidence interval widths. Results showed that I-index only performed well for a few cases.
