Parental reports of adolescent substance use were compared to the adolescents' self-reports using identical scales. Congruence was defined as exact agreement on whether adolescents were current users, ex-users, or never-users. Both parents were found to be less accurate in predicting their adolescents' alcohol use compared to cigarette or marijuana use. Single mothers were significantly less likely to be congruent than were mothers from two-parent households. Mother and father congruence on all substances was unrelated to the adolescent's sex, race, or after school employment. For both parents, congruence for adolescent marijuana use was significantly related to the age and GPA of the adolescent. Congruence may also reflect important properties of family functioning, as significant relations were found between both adolescent and parent ratings of family cohesion and parent-adolescent congruence on perceptions of marijuana use.This research was supported by Grant DA03706 from the National Institute of Drug Abuse (Hyman Hops, Principal Investigator).Jennifer Langhinrichsen is a doctoral candidate in psychology interested in adolescent and family interactions. The other authors are psychologists or data analysts working on family influences on substance use and mental health.  相似文献

The dimensions of Type A behavior were studied in 990 randomly selected adolescents and their conceptualization was clarified in terms of achievement striving, self-concept, and sense of control. The methods used were the AFMS to evaluate Type A behavior, the Nowicki-Strickland Locus of Control Scale, and Coopersmith's Self-Esteem Inventory. Achievement striving was assessed using the questionnaire designed for this study. It was revealed that Type A consisted of two independent dimensions, both adding an equal contribution to the total score. One was an impatient, aggressive competitiveness related to a low self-esteem, low self-set achievement standards, and external locus of control. The other Type A exhibited competitiveness related to a sense of responsibility, leadership, social activity, high achievement striving, and high self-esteem. These factors may distinguish maladjusted competitiveness from healthy ambition and suggest that it is important to distinguish risk Type A individuals from Type A's who are potential leaders in society.Received Ph.D. in Psychology from the University of Helsinki, Finland.
