A longitudinal design was employed to test the main and stress-moderating effects of young adolescents' perceived family environment (Family Environment Scales; FES; Moos & Moos, 1981) on their depression, anxiety, and self-esteem. This study was part of a larger longitudinal project (L. Cohen, Burt, & Bjorck, 1987) that demonstrated the significant cross-sectional effects of the young adolescents' controllable and uncontrollable negative events, and the significant longitudinal effects of the former. The present cross-sectional analyses demonstrated the hypothesized main effects of the FES scores; families perceived as cohesive, organized, and expressive were related to positive psychological functioning, whereas families perceived as conflict-ridden and controlling were related to negative functioning. However, in general these effects were nonsignificant in the longitudinal analyses. Although there were a number of significant Negative Events x FES interactions, in no instance did the pattern support the hypothesized stress-buffering role of positive family climate.  相似文献

The social support patterns of a sample of 101 suicide attempters were compared with the patterns of a control sample on the basis of structured interview data. Network characteristics and the extent of support in different functional categories were examined as to their absolute and relative power to discriminate between the suicide attempters and the controls. A clear separation of the functions of kin and of friends/acquaintances emerged. The crucial difference between the attempters and the controls lay in the number of friends with whom the subjects had agreeable everyday interactions and in the number of kin that provided crisis support, both psychological and instrumental. Other support differences between the two groups were of secondary importance. While there was no overall difference in the frequency of social interactions between the two groups, the size of the social network differed greatly. Consequences for the conceptualization and measurement of social support as well as for the prevention of suicidal behavior are discussed.  相似文献

The status of a fully indigenous mental health program serviced and controlled by the Tohono O'odham (Papago) Indian tribe is reviewed from the perspective of its 17-year history. The program functions in large measure in a crisis intervention model, with suicidal or acutely disturbed cases being most frequent. However, a whole range of disorders and ages are seen. Traditional Medicine Men and Women are often used as consultants, as are some professionals. In recent years child sex abuse and abuse of drugs among youth are prominent problems. The program experienced problems of obtaining services off reservations for patients in need, and in establishing credibility of the Indian Mental Health workers with the outside service providers.  相似文献

In a study of air traffic controllers, religious differences are found in the way Type A behavior is associated with several health status indicators. Associations between the Jenkins Activity Survey (JAS) and physical illness incidence, health-promotive behavior, diastolic and systolic blood pressure, subjective distress and impulse control problems, and alcohol consumption are examined by religious attendance, religious affiliation, and change in affiliation. Findings confirm that Type A does not vary significantly by religion. However, there are several significant findings between Type A and various health indicators. Type A is associated with illness incidence, overall and more strongly in several religion, subgroups. Type A and alcohol consumption are related positively in Protestants and converts, and negatively in churchgoing Catholics. Type A is related to impulse control problems in churchgoing Protestants and to subjective distress in churchgoing Catholics. Finally, in individuals with weak or no religious ties, Type A is associated with lower blood pressure. This last finding suggests that in some people (for example, the irreligious or unchurched), the coronary-prone behavior pattern may have cardiovascular effects which are salutary in at least one respect.The authors wish to thank Dr. Kyriakos S. Markides and Laura A. Ray for their assistance with this study. Address requests for reprints to Dr. Levin at the Institute of Gerontology, 300 North Ingalls, Ann Arbor, MI 48109.  相似文献

This essay reports a program of research as the occupational and personal stress experienced by contemporary American clergy. Three studies are reported. In the first survey a group of largely Roman Catholic religious reported less stress than the general population. In a replication of this investigation on over 510 Protestant clergy this impression of less experienced stress and greater personal resources was confirmed. In the most recent study of clergy in Southern California, a mixed picture was observed. Although the impression of less overall stress was confirmed, great differences in layclery role expectations were observed.He is the coauthorof Clergy Malpractice: How to Care Carefully (Westminster Press, 1986) and is engaged in a variety of ministerial studies.Paper presented at the meeting of the International Council of Psychologists, Mexico City, September, 1984.  相似文献
