In this study of 62 African American families living in poverty, we examined the main and interactive effects of psychological, family, and school factors on students' grade point average across the middle school transition. Both parent interviews and student surveys were collected, resulting in three major findings. First, students experienced a significant decline in grade point average across the transition from elementary to middle school. Second, students who felt more academically efficacious had higher grade point averages across the transition than did their peers. Third, significant interactions were found between family and school factors. These results suggest that rather than focusing exclusively on either parental involvement or the school environment, the combination of both family and school factors may be most effective in supporting the academic achievement of poor African American students during the transition to middle level schools.  相似文献

The family functioning of 30 nonhandicapped and 30 learning handicapped adolescents and their parents was examined. Measures of adaptability, cohesion, and communication were taken from the parent and the adolescent perspectives. Parent and adolescent perspectives on these areas of functioning were analyzed with a cluster analytic technique, which resulted in five distinct profiles of family functioning. These statistical groupings were confirmed by information gathered through participant observation from an accompanying investigation. The nature of the five clusters confirmed the existence of similar family functioning across the nonhandicapped and learning handicapped groups. Additionally, variations in reaction and adjustment to the amount of structure in the family environment by different families was documented. The importance of considering adolescent and parent perspectives separately was highlighted.Received degree from University of California, Riverside.

This paper reports on sexual behavior, knowledge of sexually transmitted diseases (including AIDS) and condoms, and condom use among African-American and white incarcerated adolescents in Seattle, Washington. One hundred nineteen adolescents in a juvenile detention facility completed questionnaires that assessed their lifetime and recent sexual behaviors, an objective test of disease and condom knowledge, attitudes and norms regarding condom use with steady and casual partners, prior condom use, and intentions to use condoms. The results indicate that these adolescents are at high risk by a number of indicators: They have a high average number of partners, have unprotected vaginal and anal sex, and many have sex with known or suspected drug users. Their overall knowledge of condoms and sexual transmitted diseases risks is high, but high knowledge is not correlated with positive attitudes; for one attitude measure, high knowledge is significantly correlated with negative attitudes toward condom use. These findings suggest that programs designed solely to increase knowledge are unlikely to effect behavior change.This research presented in this paper was supported by a research grant from the National Institute of Allergy and Infectious Diseases.Received Ph.D. in social psychology from the University of Washington.

Decision making stituations, particularly those involving societal issues, can pose very complex problems for practitioners and investigators from a broad spectrum of disciplines. In this paper, we present theoretical constructs and an organized general framework for studying such complex decision processes. The postulated facets are used in the construction of several hypotheses. Empirical evidence is presented which supports the hypotheses and argues for the viability of the proposed conceptual framework.Supported in part by OWRT Grant No. 8933-55-13645.  相似文献
