This paper examines whether variables consistent with problem behavior theory predict grade of onset of first intercourse and adoption of effective contraception. A total sample of 3,419 Wisconsin adolescents in Grades 7, 9, and 11 participated in a survey of health-related behaviors administered 3 times across a 6-year period. The sample is 87% White. Multiple regression methods generated different models for onset of sexual intercourse vs. contraceptive adoption. Consistent with problem behavior theory, sexual onset is predicted by the adolescent's behavioral system, perceived peer substance use/abuse, importance of friends, and extent to which the adolescent felt harried and believed it was okay to break laws. Contraceptive adoption is predicted by family structure, socioeconomic variables, and self-esteem. Age and gender model differences emerged. 相似文献

To determine the relative impact of a number of family variables on children's performance of gender-typed household tasks, this study took account of the gender of the child, the gender of a sibling within the same age range (8–14 years), whether a first or second child and three parental variables: the degree of encouragement given to perform masculineand femininetasks, parental involvement in the same tasks, and parents' general egalitarianism. The sample consisted of 191 white, mainly Anglo Australian two-parent families, with the two oldest children in a boy—boy, girl—girl, boy—girl, or girl—boy sequence. To check on the robustness of effects, measures were taken on two occasions, on average 16 months apart. Among the family context variables, the gender of the child was the strongest contributing variable, with girls doing more feminine tasks than boys and boys doing more masculine tasks than girls. There was limited support for the proposition that first children do more housework than second children of the same gender, while the results for gender of sibling were small and inconsistent. Among the parental variables, encouragement had strong positive effects for feminine tasks (i.e., more encouragement by parents corresponded to more involvement by children). In contrast, parental involvement in the same tasks (modeling) and parental egalitarianism predicted only the performance of masculine tasks, and the direction of the effects was mostly negative (e.g., the more a father was involved in masculine tasks, the less a child did of those tasks). The results point to involvement in gender-typed activities being influenced by multiple factors, with parental encouragement and gender of child being most prominent among these. They also point to the value of sampling on more than one occasion and of considering separately the performance of feminine and masculine tasks.

Levels and correlates of parental support, peer support, partner support, and/or spiritual support among African American
and Caucasian youth were examined in three contexts: adolescent pregnancy (Study 1), first year of college (Study 2), and
adolescence and young adulthood (ages 15–29; Study 3). Partially consistent with a cultural specificity perspective, in different
contexts different support sources were higher in level and/or more strongly related to adjustment for one ethnic group than
the other. Among pregnant adolescents, levels of spiritual support were higher for African Americans than Caucasians; additionally,
peer support was positively related to well-being only for African Americans whereas partner support was positively related
to well-being only for Caucasians. Among college freshmen, family support was more strongly related to institutional and goal
commitment for African Americans than Caucasians; conversely, peer support was more strongly related to institutional and
goal commitment among Caucasians. Among 15 to 29-year-olds, levels of parental support and spiritual support were higher among
African Americans than Caucasians; additionally, spiritual support was positively related to self-esteem for African Americans
but not for Caucasians. Implications and limitations of the research are discussed.

The present study examined the validity of the Social Problem-Solving Inventory (SPSI) and SPSI—Revised in differentiating 65 high-suicidal from 63 depressed, low-suicidal college students. Results from multivariate analyses indicated overall differences in problem-solving between these two groups as measured by the SPSI but not by the SPSI-R. Further examination of these differences revealed the high-suicidal group was different in problem-solving orientation, rather than problem-solving skills, compared to the depressed, low-suicidal group. However, when depression was statistically controlled in hierarchical regression analyses, none of the problem-solving measures predicted group membership. The superiority of the SPSI to the SPSI-R in differentiating these two groups appears to be accounted for by the elimination of 28 items in the revised version, many of which measure orientation to problem-solving. Also explored was the possibility that objective measures of problem-solving provide a better prediction of adjustment than do self-report measures. 相似文献

Abstract— When two shapes that differ in orientation or size have to be compared or objects have to be recognized from different viewpoints, the response time and error rate art systematically affected by the size of the geometric difference. In this report, we argue that these effects are not necessarily solid evidence for the use of mental transformations and against the use of invariants by the visual system. We report an experiment in which observers were asked to give affine-invariant coordinates of a point located in an affine frame defined by three other points. The angle subtended by the coordinate axes and the ratio of the lengths of their unit vectors systematically affected the measurement errors. This finding demonstrates that the visual system's measurement of invariants need not itself be invariant. 相似文献

This report explores the relationship between philosophy and medicine in the Netherlands. In Section 1 we outline the ups and downs of medico-philosophical research in our country: pre-war flourishing, post-war decline, and modern renaissance. In Section 2 we review recent Dutch literature in the philosophy of medicine. The topics dealt with include methodology of medical science, alternative medicine, the basic concepts of medicine, anthropological medicine, medicalization, medicine and culture, and health care ethics. 相似文献

This study was designed to test the hypothesis, derived from past research, that Fear of Success should be an insignificant motivational determinant among black college women. Fifty-five black undergraduates from Radcliffe College participated in two one-hour sessions where motive and performance measures in a series of achievement-related situations were obtained. Among middle-class women, nAchievement was the major positive determinant of the achievement-related behaviors under investigation while Fear of Success, measured by Horner's new experimentally derived scoring system, facilitated rather than inhibited performance. For women of working-class origin, Fear of Success exerted the strongest influence on behavior and inhibited achievement-striving in nontraditional directions. The findings among middle-class women support the prevailing opinion that black women are more achievement-oriented than their white counterparts, but the results for working-class women challenge the findings of earlier studies based upon the original measure of Fear of Success imagery and suggest that an internalized conflict over achievement and feminine identity may be a salient motivation among some black women. 相似文献
