Adolescent depression: Why more girls?

Although there has been evidence for some time of a sex difference in depression, relatively little research has examined the developmental process by which women come to be at greater risk than men for depression. In this paper, the developmental pattern of depressed affect is examined over early and middle adolescence, with a special focus on the patterns of boys as compared to girls. In addition, a developmental model for mental health in adolescence is tested for its power in explaining the emergence of gender differences in depression. Longitudinal data on 335 adolescents randomly selected from two school districts were used to test the hypotheses. Results revealed that girls are at risk for developing depressed affect by 12th grade because they experienced more challenges in early adolescence than did boys. The sex difference in depressed affect at 12th grade disappears once early adolescent challenges are considered.This research was supported in part by grants MH30252/38142 to A. Petersen.

China’s environment: Foreign trade and investment and international organizations

Not only is China’s environment in decline, but China’s contribution to global environmental deterioration is significant. Because of the global implications of China’s environmental pollution, international action is needed. Foreign trade and investment should be encouraged to incorporate environmental concerns and technology transfer, especially in the area of energy efficiency. Continued and enhanced international cooperation as well as loans and investment through international and regional organizations should also contribute to improving China’s and the global environment. Finally, China should assist in this process by continuing domestic economic reform and the open door policy. Environmental and economic benefits will result from efforts in these three areas.     

Approach and avoidant coping: Implications for adolescent mental health

We conducted a short-term longitudinal study examining the structure of coping behavior and the relationship between coping style and depression during adolescence. The sample consisted of 603 adolescents in Grades 6–11 who were surveyed in the fall of 1989 and again in the fall of 1990. A two-dimensional model of coping was found using confirmatory factor analysis with the factors being approach and avoidant coping. Four cross-sectional and seven longitudinal coping groups were formed to explore group differences in depression. Approach copers reported the fewest symptoms of depression, while avoidant copers reported the most. Subjects who changed over time from approach to avoidant coping evidenced a significant increase in depressive symptoms, whereas subjects who switched from avoidant to approach coping displayed a significant decrease in depression over a one-year period. These findings imply that adolescents who are able to elicit social support, engage in problem solving, and cognitively restructure events within a positive light are more likely to successfully negotiate the challenges of adolescence.This research was supported by a grant from the William T.

Developing economics expertise for the evaluation of primary health care

Given that government budgets are increasingly stretched in the face of competing demands, there is a pressing need for evidence on the costs and benefits of public sector investments. Nowhere is this need greater than in the health field, where the benefits of programmes are typically difficult to measure. Within the health sector a key area of interest is primary health care, which is generally regarded as a central function and the most important means by which the health of the population can be improved. This paper reports the results of a recent survey of Commonwealth countries which sought to establish the extent of economic evaluation of PHC programmes, the impact on decision-making and the level of health economics expertise available in Third World countries. Based on the results of the survey, suggestions are made for improving the commissioning and conduct of economic evaluations, for interpreting and implementing evaluation results, and for developing government expertise in economic evaluation.     

Differentiating specialists and generalists within college students' social support networks

In order to examine the relationships among social network structure, types of social support, and determinants of support satisfaction, an alternative method was used to score the Social Support Questionnaire (SSQ). Factor analysis procedures suggested that college students' (N=198) social networks consisted of four groups: nuclear family, other family, friends, and others. Satisfaction with support was positively related to the proportion of the network occupied by nuclear family and negatively related to the proportion of friends in the network. Evidence was found for the presence of both support specialists and support generalists in the networks of the college students. These results are discussed from a developmental perspective with attention to the implications for interventions.     

Self-reported delinquency and home life: Evidence from a sample of British girls

This study examines the correlation between family variables and delinquency (both self-reported and official) in a small sample of British teenage girls. Factor analysis of the 72-item Home Life Questionnaire (from T. H. Hirschi [1969] Causes of Delinquency, University of California Press, Berkeley) revealed a clear four-factor structure of caring and communication, discipline, pressure and mother-daughter closeness, which cumulatively accounted for 31% of the variance. Multiple regression of these factors onto self-reported delinquency indicated the maternal factor to be most powerful, explaining 25% of the variance in self-reported delinquency. Institutionalized and noninstitutionalized girls showed only chance differences in terms of the quality of their home life.Anne Campbell's research interests are in sex differences in antisocial behavior, especially aggression.
