There is limited empirical research on the correlates of conduct problems (CP) and depression comorbidity during childhood. This study investigated 479 elementary school children (48.2% girls). It compared children with comorbidity to children with CP only, depression only, and control children on individual, academic, social, and family characteristics. The study also analyzed gender differences in the associations between correlates and comorbidity. Multinomial logistic regression results revealed that children with CP and depression had higher levels of anxiety and more school difficulties than children with CP only, more social difficulties and more severe attention deficit and hyperactivity disorder (ADHD) symptoms than children with depression only, and more difficulties in all domains than control children. Girls with CP and depression presented a particularly negative profile, including lower school abilities than CP and control girls, and lower social skills and more severe ADHD symptoms than control girls.  Implications for evaluation and intervention planning are discussed.  相似文献

This study examined intra‐ and interindividual variations in parental legitimacy beliefs in a sample of 883 Arab refugee adolescents (Mage = 15.01 years, SD = 1.60), 277 Iraqis, 275 Syrians, and 331 Palestinians in Amman, Jordan. Confirmatory factor analyses showed distinct latent factors for moral–conventional, prudential, and personal legitimacy items. Older adolescents rated legitimacy lower for personal issues, but higher for prudential issues. Beliefs were associated with socioeconomic status (fathers' education, family size), particularly for personal issues, but were more pervasively associated with displacement‐related experiences. Greater war trauma was associated with less prudential legitimacy for all youth and more authority legitimacy over moral–conventional issues for Syrian youth. Greater hopefulness was associated with more authority legitimacy over all but personal issues.  相似文献

Job satisfaction based on familial and institutional factors was explored for 157 female counselor educators. Results indicate that female associate professors had lower levels of intrinsic rewards domain after controlling for institutional type. Parental responsibility and partnership status were equivocal, with significant interaction effects after controlling for Carnegie Classification.  相似文献

An e‐learning environment that supports social network awareness (SNA) is a highly effective means of increasing peer interaction and assisting student learning by raising awareness of social and learning contexts of peers. Network centrality profoundly impacts student learning in an SNA‐related e‐learning environment. Additionally, self‐regulation behavior significantly influences online learning of students. However, exactly how network centrality and self‐regulation influence learning behavior and effectiveness in an e‐learning environment remains unclear. Therefore, this study investigates how both variables (ie, network centrality and self‐regulation) impact student learning in an SNA‐related e‐learning environment. Analytical results indicate that the student group with high‐level centrality and low‐level self‐regulation more significantly progresses in learning achievement than the other groups. The second finding shows the group also has the highest number of students asking for help, revealing they have the highest system utilization rate.  相似文献

This study investigated Mexican immigrant parents’ reports of perceived workplace discrimination and their children's behavior, parents’ moods, and parent–child interactions. Parents of one hundred and thirty‐eight 3‐ to 5‐year‐old children were asked to complete one survey daily for 2 weeks (= 1,592 days). On days when fathers perceived discrimination, fathers and mothers reported more externalizing child behaviors, and mothers reported fewer positive child behaviors. When mothers perceived discrimination, they reported more externalizing child behaviors; fathers reported more internalizing child behaviors. Parents reported worse mood on days with perceived discrimination. Perceived discrimination was not strongly related to parent–child interactions. For fathers, but less so for mothers, those whose psychological acculturation indicated separation had more negative relations between daily perceived workplace discrimination and child and family outcomes.  相似文献

Superintendents from districts in the Minority Student Achievement Network (MSAN) challenged the Strategic Education Research Partnership (SERP) to identify an approach to narrowing the minority student achievement gap in Algebra 1 without isolating minority students for intervention. SERP partnered with 8 MSAN districts and researchers from 3 universities to design and rigorously test AlgebraByExample, a set of 42 Algebra 1 assignments with interleaved worked examples that target common misconceptions and errors. In a year-long random-assignment study, students who received AlgebraByExample assignments had an average 7 percentage point boost on a posttest containing released items from state assessments, and students in the bottom half of the performance distribution where minority students are disproportionately concentrated had an average 10 percentage point boost on a researcher-designed assessment of conceptual understanding. AlgebraByExample is easily incorporated into any existing curriculum, and naturally serves as a launch point for mathematically rich discussion.  相似文献
