Use of Phillips's five level training evaluation and ROI framework in the U.S. nonprofit sector.

Date: August 2007
Creator: Brewer, Travis K.
Description: This study examined training evaluation practices in U.S. nonprofit sector organizations. It offered a framework for evaluating employee training in the nonprofit sector and suggested solutions to overcome the barriers to evaluation. A mail survey was sent to 879 individuals who were members of, or had expressed an interest in, the American Society for Training and Development. The membership list consisted of individuals who indicated association/nonprofit or interfaith as an area of interest. Data from the survey show that training in the nonprofit sector is evaluated primarily at Level 1 (reaction) and Level 2 (learning). It also shows decreasing use from Level 3 (application) through Level 5 (ROI). Reaction questionnaires are the primary method for collecting Level 1 data. Facilitator assessment and self-assessment were listed as the primary method for evaluating Level 2. A significant mean rank difference was found between Level 2 (learning) and the existence of an evaluation policy. Spearman rho correlation revealed a statistically significant relationship between Level 4 (results) and the reasons training programs are offered. The Kruskal-Wallis H test revealed a statistically significant mean rank difference between "academic preparation" of managers with Level 3 evaluation. The Mann-Whitney U test was used post hoc and revealed ...

Creator: Boateng, Stephen
Description: The luminescence properties of Van Der Waals' dimers and clusters of pyrene and diazapyrene have been investigated. Excimers, dimeric species which are associative in an excited electronic state and dissociative in their ground state, have long been established and play an important role in many areas of photochemistry. My work here focuses on the luminescence and absorption properties of ground state dimers/aggregates, which are less understood, and allows further characterization of the ground state and excited state association of these aromatic molecules.

Mental Toughness: An Analysis of Sex, Race, and Mood

Mental Toughness: An Analysis of Sex, Race, and Mood

Date: May 2012
Creator: Beck, Nicholas M.
Description: Mental toughness has become a focus for researchers as coaches, athletes, and others extol its influence in performance success. In this study I examined mental toughness among collegiate athletes, focusing on its potential relationship to different demographic variables and to the athletes’ mood. Two hundred seventy-two student-athletes representing 12 different sports from a southwestern NCAA Division I university, participated by completing the Sports Mental Toughness Questionnaire (SMTQ), the Brief Assessment of Mood (BAM), and providing demographic information. Analyses of variance (ANOVA) assessed differences in mental toughness scores by sex, race, scholarship status, and starting status. Significant differences in mental toughness emerged between Black – White, male – female, and full – partial – zero scholarship athletes. Pearson correlations showed mental toughness was significantly related to lower levels of anxiety, sadness, anger, confusion, fatigue, and total mood disturbance, and higher levels of vigor.

Prevalence of Eating Disorders and Pathogenic Weight Control Behaviors Among Male Collegiate Athletes

Prevalence of Eating Disorders and Pathogenic Weight Control Behaviors Among Male Collegiate Athletes

Date: August 2012
Creator: Chatterton, Justine M.
Description: Training in sport environments that emphasize leanness and muscularity may damage athletes' body image and negatively influence male athletes' eating behaviors and attitudes. The Questionnaire for Eating Disorder Diagnosis and the Bulimia Test – Revised were completed anonymously online by 732 male intercollegiate athletes. Most male collegiate athletes were classified as asymptomatic (82.9%), followed by symptomatic (16%) and eating disordered (1.1%). The most common forms pathogenic behaviors were excessive exercise (51.6%), binge eating (21.4%), and dieting or fasting (20.5%). Results suggested that athletes who participate in weight class sports are at higher risk for developing these behaviors than endurance sport or ball game athletes. Counseling and other implications for professionals working with athletes are discussed.

Examining High School Coaches’ Likelihood to Refer To, Interest in Working With, and Plans to Hire a Sport Psychologist

Date: December 2013
Creator: Austin, Harlan
Description: The primary goal of the current study was to extend previous research suggesting that coaches are the primary gatekeepers who may be a barrier to working with athletes by examining high school coaches likelihood to refer to, interest in, and intention to hire a sport psychologist. Specifically, the current study examined relationships between high school coaches’ sex, age, and type of sport coached (i.e., contact vs. non-contact) and their likelihood to refer athletes to a sport psychologist for a variety of presenting issues (i.e., poor attentional focus, poor leadership, family issues, etc.). It also examined relationships between coaches’ sex, age, and type of sport coached (i.e., contact vs. non-contact) and their interest in working with a sport psychologist. Finally, the study examined reasons why coaches did not plan to hire a sport psychologist. An examination of the possible reasons that high school coaches do not plan to hire a sport psychologist served an exploratory purpose. Participants included 450 coaches who coached high school sports in the United States. Results indicated that female coaches and non-contact sport coaches were more likely to refer athletes to a sport psychologist for a variety of referral issues than male coaches and coaches of contact ...

Sexual and Nonsexual Boundary Violations Between Sport Psychology Professionals and Their Client-athletes

Sexual and Nonsexual Boundary Violations Between Sport Psychology Professionals and Their Client-athletes

Date: May 2014
Creator: Moles, Troy
Description: Sexual attraction (SA), as well as sexual (SBVs) and nonsexual boundary violations (NSBVs), have been identified as matters of ethical concern, being viewed as harmful within mental health or counseling relationships. Much of the literature in the area of SA and SBVs has focused on the counselor-client relationship, but it has been investigated only minimally in the field of sport psychology and specifically with regard to sport psychology professionals (SPPs). Because SA, SBVs, and NSBVs between SPPs and their client-athletes seem to be potentially problematic concerns in need of empirical investigation and practical scrutiny, the aim of this study was to examine: (a) the incidence of SBV and NSBV beliefs and behaviors among SPPs; (b) SPPs' feelings regarding SA for and from client-athletes; and (c) SPPs' willingness to seek supervision to manage their SA beliefs and behaviors towards client-athletes. SPPs (n = 365) completed the Survey of Applied Sport Psychologists (SASP) via e-mail or regular mail. As expected, SPPs experienced SA (40.6%) and generally did not experience strong feelings as a result of the SA. However, of the SPPs experiencing SA, 13.5% of males and 13.8% of females engaged in a SBV with a client-athlete. NSBV behaviors and beliefs are ...

ANTI Preference of the Pyramidalized Radical Center to the Two Fluorines in Difluoro Cyclic Compounds.

Date: May 2008
Creator: Tanna, Jigisha
Description: An extensive study of disubstituted cycloalkanes like CnH2n where n=3,4,5 and 6 using DFT((U)B3LYP/6-31G(d) and 6-311+G(2df,2p)) calculations is presented focusing on the effect of pyramidalization of the radical center. A potential energy surface (PES) analysis shows that the radical prefers to pyramidalize anti to the two cis fluorines in the disubstituted cycloalkanes. The degree of pyramidalization for 1,2-difluorocyclopropyl radical is 43.9o away from the cis fluorines whereas for 1,3-difluorocyclobutyl radical, 1,3-difluorocyclopentyl radical and 1,3-difluorocyclohexyl radical is 3.8o, 5.4o and 14.5o respectively away from the cis fluorines. The importance of this pyramidality effect in these compounds is discussed in context with the carbon-hydrogen bond dissociation energies (BDE's) because the preference of the radical centers to pyramidalize anti to the fluorines affects the bond dissociation energy. Importance of steric effect and unfavorable electronic interactions have been extensively explored in planar permethylated cyclobutadiene (Me4CBD) and cyclooctatetraene (Me8COT) using ((U)B3LYP/6-31G(d) and 6-311+G(2df,2p)) calculations. It is thought that steric interactions dominate electronic interactions in Me8COT, while this works opposite in case of Me4CBT. Instead, in Me4CBD the number of unfavorable electronic interactions between π bonds and out-of-plane hydrogens plays the dominant role in determining the relative energies. Interactions between the π bonds of CBD and ...

Psychosocial Mediators of the Fitness-depression Relationship Within Adolescents

Psychosocial Mediators of the Fitness-depression Relationship Within Adolescents

Date: August 2014
Creator: Sheinbein, Shelly T.
Description: Adolescence is a developmental period during which boys and girls are at high risk of developing major or minor depression. Increases in fitness have been associated with lower levels of depressive symptomatology and improvements in psychological well-being, yet the mechanisms that underlie this relationship have not been thoroughly examined. Three such psychosocial variables (i.e. body satisfaction, social physique anxiety, and physical activity self-efficacy) have been identified as possible mechanisms and although they have theoretical support, additional research is needed to demonstrate empirically the potential effects of these variables. Self-report measures were used to assess the psychosocial variables and the Progressive Aerobic Cardiovascular Endurance Run (PACER) in conjunction with age, Body Mass Index [BMI], and sex was used to determine an estimate of aerobic capacity (VO2max). Path analyses were used to test the proposed model using version 6.2 EQS Multivariate Software. Results of study revealed that the boys’ and girls’ depressive scores were determined based on the extent that their fitness levels improved their satisfaction with their bodies and lowered the anxiety they experience in relation to real or imagined judgments of their physique. Although all pathways in the model were significant, with the exception of physical activity self-efficacy to depression, ...

Intuitive Eating in Adolescents: Testing a Psychosocial Model

Intuitive Eating in Adolescents: Testing a Psychosocial Model

Date: August 2015
Creator: Dockendorff, Sally A.
Description: Intuitive eating is defined as an adaptive eating process that involves focusing on internal hunger and satiety to guide eating behavior, using those physiological cues rather than emotions to determine when to eat, and choosing what to eat based upon preference and not external rules and expectations. The purpose of this study was to examine intuitive eating within the context of contemporary sociocultural models of eating in 701 early adolescent boys and 769 early adolescent girls. Support was found for the model and suggested that pressures to lose weight or gain muscle, restrictive messages about food from caregivers, and internalization of the thin ideal were related to the early adolescents’ intuitive eating behaviors, suggesting that many of the sociocultural variables that have been found to impact disordered eating are salient for understanding healthy eating behaviors. However, the relations among many of the variables, as well as the model’s ability to explain intuitive eating overall, were stronger in girls than in boys. These findings can be used to help parents and schools begin to teach early adolescents about intuitive eating and how they can resist external pressures that may negatively influence their eating behaviors.

The Influence of Psychological Momentum on Basketball Shooting Performance

Date: May 2015
Creator: Harris, Connor
Description: The purpose of this research was to examine the influence of fictitious scoring updates on psychological momentum (PM) and athletic performance in a competitive basketball setting. The participants included in this study were 50 male undergraduate students who reported having played basketball previously and qualified by being able to make more than 24% (12 out of 50) of their 3-point shots in a pre-trial session. Participants were told that they were competing in a 50 shot, 3-point shooting competition against another individual, equal in ability. After every 10 shots, participants were given a fabricated score update and answered four questions used to measure PM. Results showed that the fictitious score updates significantly (p < .01) influenced participants’ PM scores, where those who were told they led had higher PM scores than those who were told they trailed. As for shooting performance, no significant differences (p = .76) were found between positive and negative PM states for participants who reported experiencing both during the competition. Together, these findings suggest that manufactured score updates can influence PM, but resultant performance differences may not exist. Results of this study lend support to the notion that PM is experienced by athletes. However, when examining ...

To Weigh or Not to Weigh? Relation to Disordered Eating Attitudes and Behaviors Amongst Female Collegiate Athletes

To Weigh or Not to Weigh? Relation to Disordered Eating Attitudes and Behaviors Amongst Female Collegiate Athletes

Date: May 2015
Creator: Carrigan, Kayla
Description: Collegiate and elite female athletes have been identified as a subpopulation at heightened risk for disordered eating and pathogenic weight management practices. It was hypothesized that this increases risk may be related to sport specific pressures (such as team conducted weigh-ins), or the use and frequency of self-weighing. It appears that mandatory, team conducted weigh-ins are not salient to female athletes in regards to experiencing internalization, body image concerns, dietary restraint, negative affect, and bulimic symptomatology. Results, however, indicate that frequency of engagement in self-weighing may be influential in the engagement of disordered eating symptoms. Specifically, athletes who weighed themselves three or more times per week reported significantly more internalization of general societal ideals and athletic body ideals. For body image concerns, athletes who weighed three or more times per week reported being more concerned with their body size/shape than all others. With respect to dietary behaviors, athletes who weighed themselves three or more times per week reported engaging in significantly more caloric restriction than did those who weighed less frequently. For negative affect, the athletes who weighed themselves three or more times per week reported significantly higher levels of both anger and guilt. Finally for bulimic symptomatology, athletes who ...

Longitudinal Prevalence of Disordered Eating and Weight Control Behaviors in Female Collegiate Athletes

Longitudinal Prevalence of Disordered Eating and Weight Control Behaviors in Female Collegiate Athletes

Date: December 2015
Creator: Thompson, Alexandra J.
Description: Female collegiate athletes have been established as a high-risk group for the development of eating disorders due to the high prevalence rates of clinical and subclinical eating disorders, which have ranged from 1.9% to 16.6% and 4.0% to 26.1%, respectively. Collegiate athletes appear to meet criteria for ED-NOS more often than anorexia or bulimia nervosa, and frequently engage in pathogenic weight control behaviors (e.g., dieting, excessive exercise). To date, only a few studies have examined the long-term stability of eating disorders in collegiate female athletes. The current study investigated the prevalence of eating disorders (i.e., eating disordered, symptomatic, and asymptomatic) and pathogenic weight control behaviors (e.g, binging, vomiting, laxative use) in 325 NCAA-DI female collegiate gymnasts and swimmers/divers across two time points – the beginning of their competitive seasons (Time 1) and during the final two weeks of their competitive seasons (Time 2). By Time 2, 90% of the athletes classified as eating disordered at Time 1 (n = 20) maintained clinical or subclinical eating disturbances. Of the 83 athletes originally symptomatic, 37.3% remained so and 10.8% became eating disordered. Significantly more athletes became satisfied with their bodies over the course of the season than became dissatisfied. The athletes reported ...

Personality Correlates of Anorexia Nervosa in a Nonclinical Sample

Date: December 1994
Creator: Rogers, Rebecca L. (Rebecca Lynn)
Description: The purpose of this study was to examine the relationship between anorexia nervosa and several personality traits. Past research in this area has been contradictory for several reasons. Sociocultural theories have described the media's role in promoting eating disorders by portraying a thin body-type as the ideal. However, they have neglected to describe the personality ideal which our society promotes in women. It is proposed here that anorexics incorporate and oppose this ideal. Therefore, the anorexic personality is one filled with conflict.

The Influence of Parental Conflict on Late Adolescent Perceptions of Parental Support

The Influence of Parental Conflict on Late Adolescent Perceptions of Parental Support

Date: August 1998
Creator: Flint, Pamela
Description: The question addressed in this study is whether either parent's conflict style affected the supportive quality of the parents' relationship with the son or daughter. It was important to explore variables that affect support because supportive relationships with parents have been related to adolescent adjustment. Past studies have suggested parental conflict has a negative impact on the parent-adolescent relationship. Research in the area of mediators of perceived support in the parent-adolescent relationships is limited. This study focused on perceived support in the specific relationship of the parent and adolescent. Qualitative measures of conflict were used since they have been more strongly related to changes in parent-adolescent relationships than quantitative measures. In this study the supportive quality of the parent-adolescent relationship was operationalized as a measure of parental support, depth of the parent-adolescent relationship, and conflict in the parent-adolescent relationship (Quality of Relationship Inventory).

A model for the development of disordered eating among lesbians

A model for the development of disordered eating among lesbians

Date: August 2002
Creator: Joshua, Michelle D.
Description: It has only been in recent years that eating disorder researchers have begun focusing on sexual orientation as a variable that may affect prevalence rates. Heeding the call for studies that extend beyond identification of fixed eating disorder risk factors (e.g., gender), this study was designed to explore factors that contribute to the development of disordered eating among lesbians. In this study, a hypothesized Lesbian Model of Disordered Eating was tested using structural equation modeling. Lesbian Sexual Identity and Social Supports were hypothesized to positively influence Psychological Health. In addition, Internalization of U.S. Societal Norms of beauty and attractiveness was hypothesized to negatively affect Psychological Health. Psychological Health, in turn, was hypothesized to negatively influence Body Image Concerns. Body Image Concerns was then hypothesized to positively affect Disordered Eating. The fit of the model was evaluated and one of the hypothesized pathways, Internalization of Norms was moved to directly predict Body Image Concerns. After adjusting the model, the model accounted for 54% of the variance in disordered eating. Most notably, the results highlight the potential affects of adopting a positive lesbian identity on disordered eating and underscore the importance of including sexual identity as a demographic variable in studies of ...

Psychological correlates of eating disorders: Exploring the continuum perspective.

Date: August 2002
Creator: Cohen, Diane L.
Description: Psychological and behavioral characteristics of female undergraduates with varying levels of disordered eating, as measured by the Questionnaire for Eating Disorder Diagnoses (Q-EDD; Mintz, O'Halloran, Mulholland, & Schneider, 1997), were investigated. Results suggest that the Q-EDD is an appropriate instrument for measuring eating disorder symptomatology. Greater disordered eating was associated with more bulimic, dieting, and weight fluctuation symptoms, higher impression management and approval-seeking needs, more dichotomous thinking, self control, and rigid weight regulation, and increased concern with body shape and dissatisfaction with facial features. Eating-disordered and symptomatic women evidenced more severe eating disorder behaviors and psychological distress than asymptomatic women. Findings are congruent with a redefined discontinuity perspective of eating disorder symptomatology. Treatment implications and campus-wide preventions are suggested.

Multiple Predictors of College Adjustment and Academic Performance for Undergraduates in Their First Semester

Multiple Predictors of College Adjustment and Academic Performance for Undergraduates in Their First Semester

Date: May 2001
Creator: Stoever, Shawn
Description: College success, as defined by adjustment to college and academic performance, is a multidetermined with a number of contributing influences, including academic factors, personality variables, family characteristics, and environmental factors. This study attempted to provide an organizing model of the college success literature that was based on previous research (e.g., Aspinwall & Taylor, 1994) and current stress-coping theory (Moos & Swindle, 1990). Structural equation modeling analyses indicated that the hypothesized model did not fit the data well. However, subsequent regression analyses did validate the view that college success is multidetermined. Specifically, academic performance was predicted by a combination of academic factors (SAT score and class rank) and academic adjustment. In turn, academic adjustment was predicted by locus of control, perceived social support, and high school class rank. Personal adjustment was predicted by coping strategies employed, parents who fostered autonomy, locus of control, self-esteem, and high school class rank. Finally, social adjustment was predicted by optimism, coping strategies employed, and locus of control. Treatment implications as well as directions for future research were discussed.

Creator: Arvidson, Cody Jean
Description: This study explored the relationship between cheating among university students and their cognitive developmental levels, use of neutralization techniques, self-concept as a multifaceted cognitive construct, and attitude toward cheating. The purposes of this study were to investigate: (1) The relationships between academic dishonesty and each of the following overall independent variables: cognitive development, use of neutralization techniques, self-concept as a multifaceted cognitive construct, and attitude toward cheating, and (2) the reasons behind college student academic cheating behaviors. The study used data from anonymous, self-report surveys administered to undergraduate students in-class and at supplemental sessions. Student participation was voluntary. The study was correlational. The five hypotheses were: (1) Self-concept is significantly and negatively related to academic dishonesty; (2) Cognitive development is significantly and negatively related to academic dishonesty; (3) Attitude toward cheating is significantly and negatively related to academic dishonesty; (4) The use of neutralization techniques is significantly and positively related to academic dishonesty; (5) Cognitive development, self-concept, and attitude toward cheating will make significant contributions to the regression model for the dependent variables of academic dishonesty. The data supported the first, third, and fourth hypotheses. However, the second and fifth hypotheses were supported under certain conditions. The roles of cognitive ...

Intuitive Eating Scale: An Examination Among Adolescents

Intuitive Eating Scale: An Examination Among Adolescents

Date: December 2011
Creator: Dockendorff, Sally A.
Description: Intuitive eating assesses the degree to which individuals eat based on physiological cues rather than emotional or situational cues. The Intuitive Eating Scale was initially developed using college women. This study extends the work of Tylka and reports on the psychometric evaluation of the Intuitive Eating Scale (IES) in a sample of 515 middle school boys and girls. Exploratory factor analysis uncovered 4 factors: unconditional permission to eat, eating for physical rather than emotional reasons, trust in internal hunger/satiety cues and awareness of internal hunger/satiety cues; confirmatory factor analysis suggested that this 4-factor model adequately fit the data after 4 items with low factor loadings were deleted. Supporting its construct validity, IES scores were negatively related to body mass index, body dissatisfaction, negative affect, pressure for thinness, and internalization of the thin ideal, and were positively related to satisfaction with life, and experiencing greater positive affect.

The Parent-Initiated Task Motivational Climate and Factors Influencing Eighth Grade Boys’ Intention to Continue Sports

Date: August 2011
Creator: Force, Erica C.
Description: The motivational climate, as defined by parents’ behaviors, and athletes’ goal orientations are essential in understanding children’s experiences with sport. The purpose of this study was to examine the perceived motivational climate created by parents, and its relationship to psychological outcomes experienced by adolescent male athletes in youth sports. In particular, the parent created task climate was examined through its influence on goal orientation and subsequently to psychological outcomes experienced in sport, specifically, sport competence, self-esteem, enjoyment, and intention to continue participating in sport. Participants were 405 8th grade male athletes (mean age = 13.5); (Sample A: n = 205; Sample B: n = 200). As expected, the task-oriented parent initiated motivational climate was associated with the boys’ mastery goal orientation. Participants with higher mastery goal orientation had greater sport competence, self-esteem, and more enjoyment in sport. Intention to continue playing sport was predicted primarily by their level of enjoyment, and secondarily by their increased feelings of self-esteem.

The Effectiveness of a Learning Strategies Course on College Student-Athletes' and Non-Athletes' Adjustment, Academic Performance, and Retention after the First Two Years of College

Date: December 2007
Creator: Tebbe, Carmen M.
Description: This study replicated and extended previous research I had performed that suggested that a student success course is an effective intervention to assist student-athletes in the adjustment to college. Participants in the current study included 4 groups of students, including (1) non-athletes and (2) student-athletes who were mandated and enrolled in the student success course, and (3) non-athletes and (4) student-athletes who were not mandated and did not enroll in the student success course. Overall, results from the current study suggested that the student success course was effective in helping non-athletes and student-athletes learn key cognitive strategies that are necessary for college success. In addition, results indicated that after taking the student success course, academically at-risk students earned equivalent grades, percentage of hours passed, and retention rates compared to their peers who were not classified as being academically underprepared. Finally, adjustment patterns of all groups were examined, with particular emphasis on the decrease in adjustment over the course of the semester that was demonstrated by the student-athletes. Intervention implications and future research directions are discussed, specifically in terms of how to address the unique needs of college freshmen student-athletes.

Photophysical studies of silver(I), platinum(II), palladium(II), and nickel(II) complexes and their use in electronic devices.

Date: December 2007
Creator: Hudson, Joshua M.
Description: This dissertation deals with two major topics that involve spectroscopic studies of (a) divalent group 10 metals and (b) silver(I)-phosphine complexes. The scope of the work involved the delineation of the electronic structure of these complexes in different environments and their use in electronic devices. The first topic is a look at the luminescence of tetrahedral silver(I)-phosphine complexes. Broad unstructured emissions with large Stokes shifts were found for these complexes. Computational analysis of the singlet and triplet state geometries suggests that this emission is due to a Jahn-Teller type distortion. The second topic represents the major thrust of this research, which is an investigation into the electronic structure of M(diimine)X2 (M= Pt(II), Pd(II), or Ni(II); X = dichloro, or dithiolate ligands) complexes and their interactions with an electron acceptor or Lewis acid. Chapter 3 assesses the use of some of these complexes in dye sensitized solar cells (DSSCs); it is shown that these complexes may lead to a viable alternative to the more expensive ruthenium-based dyes that are being implemented now. Chapter 4 is an investigation into donor/acceptor pairs involving this class of complexes, which serves as a feasibility test for the use of these complexes in organic photo-voltaics (OPVs) ...
