This study investigated the relationship between school start times and academic and school behavioral outcomes among adolescents. Academic achievement test data from five high schools in a Southwestern school district were compared prior- and post- a school start time change. Behavioral discipline reports were also examined to determine if earlier start times resulted in more behavioral problems for students. Results indicated minimal changes in academic achievement scores, with some significant differences between school start times when examining students' performance by pass/fail categories. Behaviorally, there were statistically significant differences between school start times with regards to high frequency referrals (i.e., attendance-related and defiance and disrespect towards authority), and total Office Discipline Referrals. Results are discussed in relationship to previous research on sleep and school start times along with the implications for adolescent school performance.

This study examined the mediating role of children's self-reported appraisals in the relation between interparental conflict intensity and child adjustment. Both parent-reported and child-reported conflict intensity were used as predictor variables. Findings suggested that children's total appraisals mediated the relationship between child-reported conflict intensity and all four outcome variables (conduct disorder, depression, anxiety, and total adjustment). Additionally, children's appraisals of negative evaluation by others mediated the relationship between child-reported conflict intensity and depression, and both rejection and negative evaluation by others mediated the relationship between child-reported conflict intensity and anxiety. Only one mediational relationship was established when assessing conflict intensity through parent report, with children's appraisals of harm to others mediating the relationship between parent-reported conflict intensity and anxiety. Findings from this study outline the importance of assessing conflict and appraisals from the child's perspective as results indicated a higher level of mediating effects of child appraisals in the relation between conflict and child outcomes when assessing conflict from the child's perspective.

This dissertation study examines the coping methods and attributional styles of peer victimized children versus those who are not involved with acts of bullying. Data corresponding to elementary school children (n=317) over a period of four years from four public elementary schools in the Southwest United States was used in the present study. Latent class analyses and correlations were conducted to explore (1) whether externalizing versus internalizing or passive emotional reactions differentially influence the attributions children make regarding victimization, (2) whether externalizing types of emotional reactions differentially influence the coping methods victimized children utilize, and (3) whether children identified as "bullies" experience different types of emotional reactions than those identified as "victims." Findings revealed that children who identified as self-reported victims tended to report higher levels of internalizing feelings. However, contradictory to what was hypothesized, the victim group also reported higher levels of being mad. Specific patterns arose between the types of attributions that victimized and non-victimized children made, where the children who identified more frequently as being victims tended to report that they believed bullying took place due to reasons that were more personal in nature and more stable. Lastly, findings also revealed similarities in the ways victimized children coped with bullying.

The five-factor model of personality is a conceptual model for describing personality, and represents five traits which are theorized to interact with each other to form personality. The Big Five Questionnaire-Children (BFQ-C) was developed by Barbaranelli, Caprara, Rabasca and Pastorelli (2003) specifically to measure the five factor model in children. The original version was in Italian, but it has subsequently been translated and used in Dutch, German, and Spanish samples. Given that the BFQ-C has support in Europe, obtained in four different languages it seems promising as an assessment of personality for English speaking children and adolescents. The BFQ-C was translated into English utilizing translation and back translation in order to maintain a high conceptual equivalency. The current study utilizes principal components analysis in order to examine the structure of the English language translation of the BFQ-C in a sample of American adolescents. Results indicate that in contrast to the Italian study, findings from this study suggest a six component solution as the most effective interpretation of the data.

The purpose of this exploratory study was to determine which social-emotional skills may predict postsecondary enrollment for students with disabilities. Students with disabilities are less likely to enroll in any form of postsecondary education and in turn experience poorer post-education outcomes than their general education peers. Using data from the second National Longitudinal Transition Study (NLTS2), a classification tree analysis was conducted on teacher-rated social-emotional behaviors in an attempt to determine which social-emotional skills were the strongest predictors of postsecondary enrollment. Items assessing social-emotional skills were selected from the second wave of teacher surveys based on their alignment with the broad taxonomy of social-emotional skills created by Caldarella and Merrell. The results of the classification tree analysis showed that one of the selected social-emotional items, teacher rated ability to follow directions, was the most significant predictor of postsecondary enrollment for students with disabilities. In general, the results suggest that compliance and, to a lesser extent, peer-relations skills, in addition to family income, predict postsecondary enrollment for students with high-incidence disabilities. This finding suggests that social-emotional skills play an important role in postsecondary enrollment for SWD, providing support for the use of social-emotional skills interventions in improving postsecondary enrollment rates and potentially post-educational outcomes for SWD.
