This study uses data from adolescents matched with data from their friends to examine whether reference group effects on adolescent sexuality should be thought of as operating through the sharing of norms or the modeling of behavior. We observe that perception of attitudes has such a trivial reality component and such a strong autistic component that it cannot serve as a mechanism of peer influence. Perception of sexual behavior has a reality component which is as large as its autistic component, and large enough to serve as a route of influence. We reach two conclusions: (1) Reference group effects on adolescent sexual behavior probably work through behavior modeling rather than through normative influence. (2) Studies which infer peer influence on sexual behavior using only perception of peers will arrive at erroneous conclusions.  相似文献

The social adjustment of the adolescent offspring of parents with bipolar affective disorder (n=41) was compared to that of the offspring of parents with nonaffective psychiatric disorders (n=22) and the offspring of normal controls (n=26). In addition, the relationship between social adjustment and cyclothymia in offspring was determined. Social adjustment was assessed using the Life Activities Inventory, a new measure developed to assess social functioning in adolescents and young adults. Cyclothymia was assessed with the General Behavior Inventory. As a group, the offspring of bipolar parents did not differ significantly from either control group on social adjustment. However, the cyclothymic offspring of bipolar parents exhibited significantly poorer social adjustment than the noncyclothymic offspring of bipolars and the offspring of psychiatric and normal controls. These findings suggest that poor social functioning in the adolescent offspring of parents with bipolar illness may be associated with the early manifestations of affective disorder. In addition, these data indicate that despite its subsyndromal intensity, cyclothymia can result in significant social impairment.This study was supported in part by National Institute of Mental Health (NIMH) Research Grant MH-39782 to Daniel N. Klein and NIMH Grants MH-33083 and MH-37195 to Richard A. Depue.  相似文献

In the kibbutz today, there are no ideological or economic barriers to prevent a couple from deciding to divorce. Both husband and wife are assured continued economic security and equal opportunities for co-parenting, thus reducing fears of disruption in the daily contact with the children. In spite of these favorable circumstances, marital breakups in the kibbutz are less frequent than in the larger cities in Israel. In recent years, however, at a time when a stronger and more intensive family life has gained legitimacy within the kibbutz structure, there is a marked tendency toward a rise in the rate of divorce. In this article we analyze the possible causes of the variations in the frequency of divorce within the kibbutz framework.The authors express appreciation to Esther Mivtzari, a psychologist on the staff of the Kibbutz Child and Family Clinic and a member of the religious kibbutz Ein-Tzurim, for assistance in gathering data on divorce in the religious kibbitzum.  相似文献

Homosexuals, bisexuals, and heterosexuals were compared on self-reported love preferences and ideals. In general, the three groups tended to agree on ideal characteristics of love objects, love relationships, and love related beliefs. Nevertheless, the groups differed significantly on preferences and beliefs related to love-object sex, residential proximity, ethnic background, physical intimacy, freedom from feelings of jealousy, sexual fidelity, emotional intimacy, and the importance of religious or legal acknowledgment.An early version of this paper was presented at the Annual Meeting of the National Council on Family Relations, in San Francisco, October 1984, Journal Series No. 2973 of the Hawaii Institute of Tropical Agriculture and Human Resources.  相似文献
