Adolescent Insomnia as a Predictor of Early Adulthood Outcomes

Description: Recent research found insomnia is a risk factor for psychiatric disorders in adults. To see if the same would be true in adolescents, the current study re-analyzed data from a national longitudinal study collected by ADDHealth that evaluated health behaviors in 4552 adolescents (mean age 14.9 years [SD 1.7]) at baseline and again 7-8 years later (n = 3489) during young adulthood. Insomnia was reported by 9.2% of the adolescents. Cross-sectionally, adolescent insomnia was associated with alcohol, cannabis, non-cannabis drugs, and tobacco use, and depression after controlling for gender and ethnicity. Prospectively, adolescent insomnia was a significant risk factor for depression diagnosis, suicidal ideation, and the use of depression and stress prescription medications in young adulthood after controlling for gender, ethnicity, and significant baseline variable. In addition, a trend was noted for suicidal attempts.

The Application of a Health Service Utilization Model to a Low Income, Ethnically Diverse Sample of Women

Description: A model for health care utilization was applied to a sample of low income women. Demographic Predisposing, Psychosocial Predisposing, Illness Level, and Enabling indicators were examined separately for African American (n = 266), Anglo American (n = 200), and Mexican American (n = 210) women. Structural Equation Modeling revealed that for African American and Anglo American women, Illness Level, the only significant path to Utilization, had a mediating effect on Psychosocial Predisposing indicators. The model for Mexican Americans was the most complex with Enabling indicators affecting Illness Level and Utilization. Psychosocial Predisposing indicators were mediated by Illness Level and Enabling indicators which both directly affected Utilization. Implications of the results for future research are addressed.

Client's Perception of Seeking Counseling as a Function of Counselor Ethnicity, Counselor Acculturation, Counselor Gender, and Client Gender

Description: Due to demographic shifts and efforts to recruit culturally diverse professionals, it is plausible that more Caucasians will encounter ethnic minority counselors in the future. Yet, the majority of multicultural literature has only emphasized Caucasian counselors' multicultural counseling competence. Research has rarely discussed how ethic minority counselors influence the perceptions of Caucasian clients. The research purpose was to explore how acculturation and gender of Asian and Caucasian counselors influence Caucasians' perceptions of the counselors and counseling services. With an analog research design, 562 Caucasian college students read 1 of 8 randomly assigned counselor descriptions, which were varied by counselor characteristics, and reported their perceptions on dependent measures: Counselor Rating Form - Short Version (CRF-S), Working Alliance Inventory - Short (WAI-S) and 4 Willingness items. With the Attitudes Toward Seeking Professional Psychological Help - Shortened Form as a covariate, 15 hypotheses were expected that Caucasians would prefer high-acculturated, same sex, and same ethnic counselors tested by simple contrast, while an exploratory question, investigating main and interaction effects among independent variables (counselor ethnicity, acculturation and gender, and participant gender) on dependent measures, was examined by MANCOVA and ANCOVA. Although only 2 of 15 hypotheses showed significance, the exploratory investigation revealed: Caucasian participants had a preference of high-acculturated counselors on CRF-S attractiveness, WAI-S and willingness to seek help. However, present data did not replicate the impression of similar ethnic matching in counseling dyads. On CRF-S expertness, Caucasian participants reported that Asian male counselors were perceived as more expert than Caucasian male counselors. For gender differences, the current finding showed that female participants were more willing to seek help for academic/career concerns, whereas male participants were more willing to discuss their somatic concerns. For the research implications, with appropriate trainings in multicultural counseling competence, both Caucasian and non-Caucasian counselors could become effective therapists. Counseling ...

Cognitive and Perceptual-Motor Indicators of Lateralized vs. Diffuse Brain Damage in Adults.

Description: Among the goals of the neuropsychological assessment are to detect the presence of brain damage, localize which areas of the brain may be dysfunctional and describe subsequent functional impairments. The sensitivity of neuropsychological instruments in carrying out these functions is a question of some debate. The purpose of this study is to determine the utility of lateralizing indicators from the WAIS-III, McCarron Assessment of Neuromuscular Development (MAND) and Haptic Visual Discrimination Test (HVDT), from the McCarron-Dial System Neuropsychological Assessment Battery (MDS), in ascertaining the presence or absence of brain damage as well as location of lesion. The classification accuracies of using performance level indicators from these tests and lateralizing indicators, alone and together, were compared.

Comparative Analysis of Chronic Versus Acute Stressors and Their Influence on Distress Consequences at Work

Description: Workplace stress has been found to be a causal agent of psychological distress consequences in employees. Chronic stressors have been well researched, in particular, role conflict, role ambiguity, and work overload have been extensively studied. A meta-analysis was conducted in order to aggregate past research to gain a better understanding of the impact these stressors have on the psychological distress consequences of depression, tension/anxiety, somatic complaints, and generalized feelings of stress. Only role ambiguity was found to be a significant contributor to psychological distress, in particular to feelings of depression and stress. In general, however, effect sizes for all three stressors were moderate to large. While chronic stressors have been well researched, acute stressors have been widely overlooked. Since research in this area is limited, the Daily Work Hassles Survey was developed and validated in order to analyze the role daily hassles play in the workplace. The survey yielded two factors, Interpersonal Hassles and Task Hassles. The former of which was found to be significantly related to the distress consequences of depression, tension/anxiety, somatic complaints, and general feelings of stress. The ultimate goal of this project was to compare chronic and acute stressors. Results from the daily hassles study were contrasted to the results of the aforementioned meta-analysis. It was found that the chronic stressors of role ambiguity, role conflict, and overload are significantly greater predictors of selected distress consequences than the acute factors of Interpersonal Hassles and Task Hassles. However, when somatic complaints was employed as the dependent variable, no significant differences were found between chronic and acute stressors.

The Cross-Validation of AD/HD Instruments and the Relationship to Neurocognitive and Behavioral Measures

Description: The purpose of this study was twofold: to determine the construct validities of comparable AD/HD instruments that were developed according to our current, DSM-IV classification system for AD/HD; and to identify potential +neurocognitive and socioemotional markers for AD/HD. The sample consisted of 145 children ages 8 to 11 years of age who were diagnosed with Attention Deficit Hyperactivity Disorder (AD/HD), or Central Auditory Processing Disorder (CAPD). Children were administered a battery of neurocognitive tests and completed a self-report measure of personality. Parents completed several, AD/HD instruments pertaining to their children. The AD/HD instruments used in this study were the Attention Deficit Disorder Evaluation Scale-Home Version (ADDES), Attention Deficit Hyperactivity Disorder Test (ADHDT), and the Attention Problems and Hyperactivity scales from the BASC-Monitor (BASC-M). Of interest was how each AD/HD instrument compared to the DSM-IV, particularly in terms of the cross-consistency of AD/HD subtype classifications. The findings showed that the AD/HD instruments classified participants differently from the initial, DSM-IV entry diagnosis. Rates of agreement were better for some of the AD/HD instruments than for others yet there was little overall consistency. The neurocognitive measures used in the study were the Cognitive Assessment System-Basic Battery scales. The socioemotional measures used in the study were two parent-report scales from the BASC-M (Internalizing Problems and Adaptive Skills), and the child report scales from the BASC-Self Report of Personality. Results showed that the neurocognitive measures were relatively insensitive to AD/HD symptomatology while a nearly opposite trend was observed on the socioemotional measures. For the most part, participants classified as the ADHD-Combined Type (ADHD-CT), (regardless of which AD/HD instrument was used) had the most significant impairment in areas of social functioning and emotional symptoms across parent and self-reports.

Depression, Activities of Daily Living, and Retirement

Description: Depression is a common clinical and subclinical psychiatric disorder in the middle-age to older adult population. This study examined the relationship between depression and activities of daily living (ADLs) in middle-age to older adults. This study examined longitudinal data from the 1998, wave 4, and 2000, wave 5, of the Health and Retirement Study (HRS), a National Panel Study sponsored by the National Institute on Aging. A negative cross-sectional and longitudinal relationship between higher ADL scores and depression was hypothesized. A goal of the present study was to determine the temporal precedence of these two constructs using a cross-lag panel design to first examine the cross-sectional relationship between ADLs and depression at time-one and at time-two, and then the time-one to time-two longitudinal relationships to examine temporal precedence possible causal relationships. Finally, differences in these correlational relationships by retirement status and then by marital status were tested. There were several interesting findings, including those who were retired in both 1998 and 2000 reported fewer ADLs (i.e., worse functioning), but also reported better health than those who were working in both 1998 and 2000. Similarly, those people who were not married in both 1998 and 2000 reported fewer ADLs but better health than those who were married in both 1998 and 2000. Married individuals reported fewer depressive symptoms than those who were not married.

Developmental Stressors and Associated Coping Skills in the Development of Disordered Eating in College Females

Description: There is a lack of clarity in the current literature in how potential etiological factors interact and result in disordered eating. The purpose of this study was to examine an expanded model of Personality, Social Support, Appraisal/Coping Processes, Abuse History, Internalization of Sociocultural Standards, Psychological Disturbances, and Body Disparagement in the development of disordered eating. The current model was evaluated using 276 women in their transition to college, a time period highly associated with symptoms believed to increase a woman's risk for the development of disordered eating including perceived difficulty coping, weight gain, and negative affect. Structural equation modeling was used to allow simultaneous examination of the causal relationships between the factors. Structural analyses confirmed that college women with previous stressful experiences appraised the adjustment to college as more stressful and reported feeling less able to cope with the transition. Those women who identified the transition as overwhelming were also aware of increased negative mood and psychological states since beginning the school semester. Further, women with previous traumatic sexual experiences appeared to be at additional risk for increased negative affective symptoms. The resulting model confirmed that those women who experience negative mood states and those that endorse strong internalization of cultural values regarding attractiveness encountered increased dissatisfaction and disapproval of their bodies. Finally, women with higher levels of body concern engaged in more eating behaviors associated with disordered eating. The roles of personality functioning and perceived social support could not be identified in the developmental model. The predictive links between constructs in the resulting model provide meaningful information regarding the transition to college and associated risks for development of disordered eating. Validation of the model in an independent sample would provide confirmation of these relationships and longitudinal research examining females' attitudes across crucial developmental periods might provide important information regarding ...

The Effect of Punishment Threat on Children's Ability to Resist Temptation to Transgress and Lie

Description: Children's response to a resistance-to-temptation (RTT) task was investigated under three punishment threat conditions: negative consequence, removing an anticipated reward, and no explicit punishment. Ninety first and second graders participated in the RTT task and seventy-three parents completed the Behavior Assessment System for Children and the Psychopathy Screening Device. As only 4% of children transgressed, results are unclear. Hypotheses tested using approximations of transgression showed no differences in RTT. Children with temperaments characterized by hyperactivity, impulsivity, attention problems, and conduct problems (HIA-CP) had the highest levels of psychopathic traits compared to all others. In addition, spanked children were rated as having significantly more behavioral problems than non-spanked children. Limitations of the current study and suggestions for future research are discussed.

The Effect of Web-Based Support as an Adjunct to a Self-Help Smoking Cessation Program

Description: For the past quarter century, the public has been educated and warned about the dangers of smoking, and both smokers and health researchers have been in search of cost-effective, smoking cessation programs that will lead to long-term cessation. This study used a randomized experimental design to investigate the effectiveness of adding Web-based support materials to a nationally sponsored self-help smoking intervention. There was no significant increase in abstinence rates nor progression through the stages of change by those participants who had access to the Web site. However, there were some overall significant trends that suggested these self-help interventions were successful at decreasing daily rates of smoking and nicotine dependency, as well as tended to encourage repeated quit attempts. Although Web-based supports did not appear to increase the effectiveness of the nationally sponsored self-help intervention, this study demonstrated overall 12 week follow-up abstinence rates of 30-32%--greater than what might be expected, given average success rates of other self-help interventions. This study also supports the notion that women may face additional barriers to smoking cessation. Limitations and implications for future research are discussed.

Employee empowerment: Relationships between location in the hierarchy, span of control, and industry type on perceptions of empowerment.

Description: The current study seeks to examine the relationships between perceptions of employee empowerment and perceptions of leadership, span of control, and industry type. Participants were gathered from an archival source employing a high school alumni e-mail group (n = 361) and a survey from 9 organizations (n = 647) and combined into a larger sample (n = 1008). The participants took Bodner's (2005) Assessment of Employee Empowerment and Assessment of Empowering Leadership instruments. Support was found to suggest that people report being less empowered than they believe that top management would report about them. Also, participants reported that their leader was less empowering than they believed top management would report about the leader. Span of control was found to impact perceptions of empowerment. Production workers reported feeling more empowered than workers in service industries. Participants did not report that leaders were more empowering if they were higher in the hierarchy (executive) than lower levels (coach, employee). Also, a respondent's position did not affect the relationship between job type and feelings of empowerment. This study suggests that the organizational design (span of control) and industry type may affect empowerment initiatives, while lower levels of the organization may view empowerment much differently than top management.

An Examination of Methodological Rigor and Its Effects on Organizational Development and Change Outcomes

Description: Organizational development and change (ODC) is a broad field because change occurs in all organizations, occurs at multiple organizational levels, consists of numerous interventions, and can impact multiple outcomes. Many ODC efforts attempt to examine the effectiveness of their initiatives, yet fail to account for the quality, or rigor of their methods. The purpose of this paper is to examine how methodological rigor and intervention implementation quality impact ODC outcomes. The results indicate that overall methodological rigor is not a significant predictor of organizational change outcomes; however, several individual rigor criteria exhibit predictive power. Implementation quality is a significant predictor of organizational outcomes, but in a negative direction.

Examining Employee Satisfaction, Customer Service and Customer Satisfaction in a Retail Banking Organization

Description: In the increasingly competitive world of retail banking, organizations are focusing their attention on customer service as a means of increasing customer loyalty and retention. With this goal of increasing customer retention, the link between the attitudes of the service provider (employee satisfaction), the customer interaction behaviors that those attitudes lead to (customer service quality), and the attitudes that those behaviors generate in the customer (customer satisfaction) has become an increasingly important area of investigation. The goal of this research is to analyze the relationships that exist between these three variables: employee satisfaction, customer service quality, and customer satisfaction in a mid-sized retail bank. Data from three separate surveys collected during the same time period in 137 branches of a regional bank are analyzed using multiple regression analysis to determine whether relationships and interactions exist at a banking center level. While results of the analyses did not show a significant relationship between the variables, issues relevant to this determination are discussed and conclusions drawn regarding the nature of these constructs.

Influence of executive function on medication adherence in neurologically impaired and non-impaired elderly.

Description: Medication non-compliance has become one of the most prevalent reasons for hospitalization and doctor's visits by the elderly. As the elderly population is more likely to have decreased cognitive abilities, it is suggested that neuropsychological factors, especially executive function, are more influential in medication non-compliance than once thought. This study looked at executive function performance on a traditional battery of neuropsychological tests, self-report of perceived ability to perform executive function tasks, and the newly developed Pillbox Test, a performance based IADL measure. The Pillbox Test is designed to replicate a type of medication-management specific IADL as a means to asses executive function. Standard executive function measures only tap a portion of executive function, but it is believed that the Pillbox Test incorporates all four theoretical domains of executive function. The multiple measures of executive function performance were compared in three prevalent subgroups of the elderly population (mixed neurological group, cardiac medical-control group, and healthy community-control group). Results found significant differences, where the community-control and cardiac groups outperformed the mixed neurological group on the large majority of executive function tasks. Smaller differences were also noted between the community-control and cardiac groups and between the cardiac and mixed neurological groups. Together, these findings provide support for the diagnostic prevalence of mild cognitive impairment in the older adult cardiac population. Results also indicated the level of executive dysfunction on standardized neuropsychological measures was highly correlated with performance on both the Pillbox Test and the IADL based Direct Assessment of Functional Status measure. Finally, the Pillbox Test has moderate to strong ecological validity with 75% sensitivity and 87.5% specificity for five or more errors on this test.

Influences of the Mother-Daughter Relationship on Motivations for Sexual Behavior

Description: The influences of family relationship variables on motivations for adolescent sexual risk-taking were investigated. Previous research has linked these variables to adolescent sexual behavior, however, the nature of these links has not been specifically examined. Family variables were operationalized as child attachment to mother, parental support of each other, parental conflict strategies, and parental monitoring. Emotional motivations were operationalized as attachment and affiliation needs. The sample consisted of 40 single females ages 18 to22 recruited from a local pregnancy care center. Predictions that parent-child relationship and parental influence would predict emotional motivations for sexual risk-taking were not supported. The variable most highly related to sexual risk-taking, though not included in the model tested, was father's destructive conflict strategies. Theoretical and methodological issues are discussed.

The Interface of Personality Processes and Cognitive Abilities: A Comparative Study of Elderly and Young Adults

Description: Although research has shown that the complex constructs of intelligence and personality are necessarily intertwined, studies exploring this issue in elderly individuals are rare. The importance attached to this interface in older adults becomes particularly clear in light of the debate over the cause and extent of age-related decrements in cognitive performance as well as whether such losses can be ameliorated or not, especially given societal shifts toward increased life expectancies. The present study explored the basis for shifts in personality-ability relationships in adulthood by comparing two samples of older adults, one of which was assessed in 1975 (N = 102, M age = 68.4), and the second of which was assessed in 1995 (N = 100, M age = 72.0), and a sample of younger adults (N = 100, M age = 21.8), also assessed in 1995. Each participant was administered the Holtzman Inkblot Technique and the Gf-Gc Sampler, a measure of crystallized (Gc) and fluid (Gf) abilities. LISREL analyses of both age-related and historical shifts in personality-ability relationships suggested that not only were such shifts associated with cohort differences as reflected in factor loading (lambda) differences between the older samples and the younger sample, as well as between each of the older samples, but also that such connections were weaker among younger adults. These findings are important in revealing that sociocultural shifts in opportunities for continued cognitive growth influence the impact of noncognitive (personality) factors on intellectual functioning in later life. Limitations of the current study, implications of the results, and suggestions for future research are discussed.

Investigation of Relational and Overt Aggression Among Boys and Girls

Description: Given the paucity of research that has been conducted on aggression in girls (see Keenan, Loeber, & Green, 1999, for a review), it is important to examine different behavioral manifestations of aggression that may be more prevalent among girls than boys, such as relational aggression (see Crick et al., 1999, for a review). Relational aggression consists of behaviors that harm others through damage to their peer relationships or the threat of such damage (e.g., spreading rumors about a peer so that others will reject him/her, social exclusion; Crick & Grotpeter, 1995). Children with Attention-Deficit/Hyperactivity Disorder (ADHD) are a particular subset of youth who are at increased risk for exhibiting aggressive behavior (Henker & Whalen, 1999; Whalen & Henker, 1985). The purpose of the present study was to assess the prevalence of relational aggression among children with attention problems as compared to the general population. Gender differences in relational aggression were also examined. In the current study, participants included 91 3rd-5th grade public school students. Teacher ratings of aggressive behavior and attention problems were obtained. Parents also completed measures to assess attention problems and social-psychological adjustment. Contrary to prediction, results indicated children with attention problems were not more aggressive than children without attention problems, regardless of the type of aggressive behavior assessed (i.e., relational or overt aggression). With respect to gender differences in relational aggression, results indicate the well-known gender effect for relational aggression only applies to Caucasian students in this sample, as a gender effect for relational aggression was not obtained for Hispanic students. Thus, the gender effect for relational aggression should not be considered a robust finding generalizable to all ethnic groups. Finally, relationally aggressive children were reported to be as well-adjusted as their non-relationally aggressive peers, which is not consistent with previous research. Regardless of aggression status, Hispanic ...

Job Embeddedness as a Predictor of Voluntary Turnover: Validation of a New Instrument

Description: Voluntary turnover has become a problem for many organizations in today's society. The cost of this turnover reaches beyond organizational impact, but also affects the employees themselves. For this reason, there has been a plethora of research conducted by both academicians and practitioners on the causes and consequences of voluntary turnover. The purpose of this study is to test the validity and generalizability of the job embeddedness model of voluntary turnover to the information technology (IT) industry. The IT field has been plagued with high turnover rates in recent years. In this study, the job embeddedness model (Mitchell et al., 2001) is applied to a population sample consisting of health care information technology employees.

Longitudinal Study of the Impact of Performance Appraisals in Organizations

Description: The purpose of this study was to determine the effectiveness of and the subjects' overall satisfaction with the implementation of an internally created performance appraisal system. The system was implemented at a major technology consulting firm in the US. The subjects of this study were manager level employees of the firm. An employee survey conducted annually at the firm included questions relating to the implementation of the performance appraisal system. Eight years of managers' responses to six key questions in the Career Development category were analyzed. Managers' perceptions of their contribution to the firm, their understanding of what career paths are available to them, their understanding of the requirements for promotion, as well as their overall satisfaction with the implementation of the performance appraisal system were captured by this survey. Trend analysis indicates that managers at the firm perceived their career path knowledge improved and their understanding of promotion criteria improved as a result of the implementation. Overall satisfaction with the implementation did not improve enough to site confidence in managers' perceptions for the period immediately after the implementation; managers' responses to the actual implementation were disagreeable to neutral. Managers did not feel their impact on the organization improved as a result of the implementation.

Narcissistic traits and parenting style: A closer look at maladaptive parenting through parent-child observations, parent self-report, and child self-report.

Description: The thrust of this paper was two-fold, 1) to confirm a 2-factor model of narcissism in women, and 2) to examine the relationship between narcissistic traits in mothers and several variables associated with parenting efficacy. Participants included 193 mother-child dyads. A 2-factor model of narcissism was confirmed in the present sample of mothers, suggesting that narcissistic traits in women may be manifested in distinct Overt and Covert forms. Contrary to expectations, Covert Narcissistic traits in mothers did not significantly correlate with observed parenting behaviors on the PCIA, including Positive Personal Comments (PPC) towards children, Negative Personal Comments (NPC), and Parental Nurturance. However, children's self-reported maternal rejection on the C-PARQ correlated positively with Covert Narcissistic traits in mothers, as did mother's self-reported dysfunctional parenting attitudes on the AAPI-2. Narcissistic traits in mothers correlated most strongly with risk of child physical abuse on the CAPI (r = .70). Results are also presented for the Overt Narcissism factor, which proved to be less stable as a factor. Overall, results emphasize the need for a more comprehensive understanding of narcissism for women, given its potential Implications for children's healthy development and parenting interventions.

NEPSY profiles in children diagnosed with different ADHD subtypes.

Description: The purpose of this study was to determine if attention-deficit/hyperactivity disorder (ADHD) subtypes (predominantly hyperactive/impulsive, ADHD-HI; predominantly inattentive, ADHD-IA; combined, ADHD-C) exhibit distinct neuropsychological profiles, using the Attention and Executive Function subtests of the Developmental Neuropsychological Assessment, (NEPSY) and the omission and commission scores obtained on the Conners' Continuous Performance Test-II (CPT-II), a test that assesses attention processes. The sample was selected using archival data collected in a neurodevelopmental clinic over the past decade and consisted of 138 children between the ages of 6 and 12 years old. Using the Diagnostic and Statistical Manual of Mental Disorders (4th ed.) (DSM-IV) criteria, the children were placed in either the ADHD-HI (n = 40), ADHD-IA (n = 35), or ADHD-C (n = 36) group, or a symptom free comparison group (n = 27). It was hypothesized that children with elevations on the impulsivity/ hyperactivity (ADHD-HI and ADHD-C) scale would be impaired on measures of inhibition and those with elevations on the inattention scale (ADHD-IA and ADHD-C) would be impaired on tests of attention, vigilance, and other executive functions. A one-way multivariate analyses of variance (MANOVA) was conducted (Group X Task), with significant results for overall main effect for group on the 7 dependent variables post hoc tests using the Tukey's honestly significant difference (HSD) revealed the following: the ADHD-HI group scored significantly lower on tests that require behavioral inhibition processes (Knock and Tap, Statue and CPT-Commission errors). The ADHD-IA group scored significantly lower on tests of problem-solving and planning (Tower) but not on tests of attention as was expected. The ADHD-C group scored significantly lower on tests of inhibition, attention, and other executive functions (Auditory Attention Response Set, Visual Attention, Tower, Knock and Tap, Statue, and CPT-Omission and CPT-Commission errors). Overall results suggest that the NEPSY Attention and Executive Function subtests are ...

Neuromotor and Neurocognitive Functioning in the Prediction of Cognition, Behavior Problems, and Symptoms at Two-year Follow-up in Youth with Schizotypal Personality Disorder

Description: Individuals diagnosed with schizotypal personality disorder (SPD) exhibit patterns of cognitive deficits, neuromotor disturbances, and behavior problems similar to individuals with schizophrenia, and thus SPD is thought to represent one point on the continuum of schizophrenia spectrum disorders (SSDs). Deficits in behavior, cognition, and motor functioning have been implicated as childhood precursors of SSDs and appear to also vary as a function of gender and family history of psychopathology. As such, studies of youth may help in further identification of individuals at risk for SSDs. The current study examined the prospective associations between problem behaviors, neuromotor and neurocognitive functioning, as well as SSD symptoms, at baseline and 2-year follow-up in youth meeting criteria for SPD, other personality disorders, or healthy controls. The neuromotor and neurocognitive measures were able to significantly predict SSD symptoms and behavior problems above and beyond baseline predictors. Overall, the findings provide further support for the role of subcortical motor centers operating together with prefrontal cortical areas in the regulation of higher-order cognitive functioning and in producing the psychiatric features of SSDs. Significant correlations between gender, family history of schizophrenia, and history of head injury with symptoms, behavior, cognition, and motor functioning were also found and highlight the importance of examining the effects of these variables in future investigations. In sum, the current study helped in identifying factors that predict the clinical course of schizotypy and may shed light on the disturbed neural circuitry underlying SSDs.

Organizational Change Development Interventions: Are Multiple Interventions Useful?

Description: The effects of multiple interventions in organizational development change were studied in a comprehensive meta-analytic review. Thirteen organizational interventions were assessed on five outcome variables based upon previous research of six major meta-analytic reviews. Findings based on 138 studies indicated that there were no significant effects of multiple interventions on positive organizational change as opposed to individually implemented interventions. The findings are not congruent with previous findings of organizational development change, and possible issues surrounding these differences are discussed.

Organizational development: A comparison of individual and organizational level change.

Description: Organizational change and development (OCD) has been studied by researchers to identify the effectiveness of change initiatives. Because of the broad scope of interventions in OCD, these studies have covered a range of areas including multiple interventions and the methodological rigor used by researchers. However, few have looked at organizational versus individual change within an organization, to examine whether individual change is more effective than organizational change. The purpose of this study is to determine if organizational change occurs in a top down or bottom up manner. A meta-analysis was conducted using 238 field experiments. Each study was coded for intervention and organizational outcome and for individual or organizational level variables. Effect sizes were calculated for each study, each level, and each level by intervention and outcome measure. Results indicate that while OCD interventions overall had a moderate effect size, the level of intervention or outcome was not a moderating variable.
