It has been demonstrated that craving for gambling is associated with anxiety and depression in pathological gamblers. Exercise has been shown to reduce anxiety and depression, as well as positively influence abstinence rates in individuals with substance use disorders. In this study, we examined the impact of a physical activity program in 33 pathological gamblers. We also analyzed the association between craving and plasmatic levels of stress hormones (adrenocorticotropic hormone, cortisol, and prolactin). The program involved eight 50-min sessions. Craving was assessed 24 h before, immediately before, and immediately after each session, as well as on a weekly basis. Before and after the program, we evaluated gambling behavior, depressive symptoms, anxiety, and plasma levels of stress hormones. We identified a significant reduction in craving following each session and at the end of the program. There was improvement in anxiety, depressive symptoms, and gambling behavior. The post-session reduction in craving was accompanied by post-program reductions in craving and anxiety but not by a post-program reduction in depressive symptoms. The craving reduction was associated with a variation in prolactin levels but not with variations in levels of cortisol or adrenocorticotropic hormone.  相似文献

The interactions of adolescent peers are the subject of both parental angst and scholarly attention. Peer influence is the most consistent predictor of adolescent drinking patterns when controlling for other background characteristics. This study extends these findings to incorporate a theoretical argument derived from status characteristics theory. Using 2980 best-friend dyads constructed from the National Longitudinal Study ofAdolescent Health ("Add Health"), I show that the peer influence process differs by the gender structure of the friendship. Adolescents in same-sex best friendships influence one another mutually, consistent with prior theoretical and empirical approaches to adolescent problem behavior: By contrast, boys in mixed-sex best friendships have influence over their female friends' drinking patterns, while the girls do not have any effect on their male friends' drinking behavior a finding consistent with status characteristics theory. The results indicate that peer influence models that do not take gender into account in the structure of the friendship misrepresent the unequal influence dynamics between boys and girls.  相似文献

Drawing from fifty in‐depth interviews, this research examines the role of existing parental language knowledge on the ethnic identity negotiation of two ethnically distinct children of immigrant groups—Vietnamese and Chinese–Vietnamese—whose families have emigrated from Vietnam to the Southern California region of the United States. While previous research focused primarily on the influence of premigration status on first‐generation immigrants, this article considers how a central aspect of premigration status (intranational ethnicity) applies specifically to the children of first generation immigrants. By taking the premigration approach of comparing the experiences of different ancestral‐origin groups from a single nation (the intranational ethnicity perspective), this analysis suggests that a family's premigration ethnic status shapes the 1.5 and second‐generation's ethnic self‐identification choices through the mediation of parental language knowledge. Specifically, for the children of immigrants with twice‐minority status (Chinese–Vietnamese Americans), parental language knowledge serves as an easy ethnic identity default during these children's early self‐identification process.  相似文献

ABSTRACT

This article describes the development and empirical status of guided Internet-delivered self-help. The treatment approach combines the benefits of bibliotherapy with book-length text materials and the support given online via web pages and e-mail. Interactive features such as online registrations, tests, and online discussion forums are also included. Cognitive behavior therapy (CBT) guided the research and clinical implementations of this approach, as it lends itself more easily to the self-help format compared with other presently available psychotherapy approaches. We include an overview of the research, current issues and research in service delivery, lessons learned through a program of research, and directions for future investigations.  相似文献

This paper describes the process of "coaching" individuals in their efforts to change themselves in the context of their nuclear and parental family systems. Although this approach is regarded as one of the major modes of intervention in family therapy, the actual methods and techniques for intervention are not widely understood. Moreover, we have expanded the Bowen approach to address powerful cultural and family life cycle influences. The goal of coaching is to help clients define themselves proactively in relationship to others in their families without emotionally cutting off or giving in. Coaching begins by training clients to become observers and researchers of their own role in the family and of family patterns of behavior. Coaching then moves to help them bring their behavior more in line with their deepest beliefs, even if this means upsetting family members by disobeying family "rules."  相似文献

Youth access to tobacco remains a significant problem for this nation. Methods have been developed to reduce youth access to commercial outlets and these involve enforcement efforts of monitoring and fining merchant offenders. In the present study, over a three year period of time, readiness to participate in these types of enforcement programs were assessed in 11 communities. Several years after the research study was completed, enforcement activities were re-assessed. Findings indicated that those communities that had made the largest changes in community readiness to enforce youth access laws during the three year intervention were the ones most likely to continue enforcement activities into the follow-up period. There is a need to better understand how youth access to tobacco community-based interventions can be maintained.  相似文献

For some time, sociologists have called for the study of the temporal characteristics of social life. Ethnomethodology and Symbolic Interactionism are two sociological theories which have begun to develop analyses of social timing. In this report, exemplary research efforts from each perspective are examined and evaluated along the temporal dimensions of the past, order, sequence, and the future. It is shown that research methods are key in elaborating or hindering the study of temporality. Specifically, Symbolic Interactionists' strategies have allowed a rich temporal orientation to be developed and specified whereas strategies employed by Ethnomethodologists have resulted in research that is confined to the immediate realm of experience and thereby have been narrow in temporal scope.  相似文献

The purpose of this paper is to offer an analysis of the nonprofit sector from the entrepreneurial point of view in order to show why the organizational form of nonprofit has arisen and, more precisely, why rational entrepreneurs choose to incorporate their business enterprises under the nonprofit regulation. Since nonprofit associations were formed before the emergence of the tax code, the favorable tax-status alone cannot explain an entrepreneurial preference for the nonprofit form. Tax considerations have then to be combined with other elements. The alternative view proposed in the paper is that the supply of factors such as capital and entrepreneurship provides the motivation for the rise of nonprofit enterprises. The entrepreneur and the managers enjoy control of the activity and see to it that service are produced in such a way as to maximize their net income. They do not ignore nonmonetary income in the sense that they find it rewarding to seek pecuniary gains as well as nonmonetary profits in any given period. To explain why an entrepreneur organizes his business as a nonprofit entity we investigate a theater production process.  相似文献

This study investigates the role of nonverbal expressiveness and self-monitoring as mediators in the communication of teachers' expectations for student performance to a third party observer. Undergraduates were recruited to be videotaped while teaching a brief lesson to a high school student who was presented as either very bright and motivated or not. Videotapes showing only the teacher were later shown to observers who were asked for their impressions of the student who was being taught. It was hypothesized that teachers who were highly nonverbally expressive would communicate their expectations to the observers, and would thus elicit from them responses quite similar to their own. On the other hand, it was predicted that unexpressive teachers would not communicate their expectations, eliciting observer responses unrelated to their own. The predictions were supported but with a major qualification: it was found that spontaneous expressiveness interacted with self-monitoring in determining expectancy communication. The findings point towards new directions in understanding the occurrence and mediation of expectancy effects.A portion of this paper was presented at the American Psychological Association meetings in Anaheim, California, August, 1983. The research was supported in part by a University of California intramural research grant to the second author, by a UCR minigrant to the third author, and by an NIH biomedical research support equipment grant.  相似文献
