Purpose

This study examines the experiences of a group of drug-abusing juvenile offenders following their release from a residential treatment facility in order to determine how pre-existing levels of strain and coping skills affect their ability to benefit from the treatment program and avoid recidivism and relapse.

Methods

During an extensive pre-treatment interview, the youths were asked a variety of questions assessing potential sources of strain (including the experience of physical/emotional abuse and intra-familial violence, parental drug use, and physical/emotional health problems) and a variety of coping (cognitive, emotional, physical, social, and spiritual) skills. We hypothesized that pre-existing strain levels would decrease the likelihood of treatment success just as pre-existing coping skills levels would enhance it, but also predicted that the impact of strain on treatment success would be moderated by existing coping skills and that coping skills would have the greatest capacity to affect treatment outcomes among youths with higher levels of pre-treatment strain.

Results

Our findings offered mixed support for our hypotheses, including evidence that some coping skills mitigated the negative impact of strain whereas others seemed to intensify it. Implications of our findings are discussed and directions for future research are suggested.  相似文献

Drawing on postcolonial literature and theories of farmer resistance, this article provides an empirically based alternative explanation of African farmer behaviours to narratives that blame them for their lack of technology adoption. Based on six months of ethnographic immersion in one district in the Northern Region of Ghanaa, we identify the ways that farmers defy commercial agriculture investment, government services and non-governmental organisation (NGO) project interventions aimed at intensification, and describe their reasons for doing so. This study interprets farmers’ acts of defiance, such as side-selling or falsely weighting their products, as insights into everyday acts of resistance. We find that throughout Ghana’s postcolonial period, agriculture intensification policy and practice have produced an environment where various development actors and farmers have both a sense of entitlement and mistrust of each other. Farmers’ acts of sabotage may be spaces where they make rational choices based on experiences of historical antecedence, including decades of failed development projects, elite corruption and mismanagement, degrading ecologies and donor hegemony.  相似文献

Previous analyses of data from the 4-H Study of Positive Youth Development (PYD) have examined concurrent trajectories of positive development and risk/problem behaviors among adolescents, finding complex and not necessarily inverse relationships among them. In this article, we expand on prior research by employing a person-centered approach to modeling risk behaviors, assessing development from approximately 6th grade through 12th grade among 4,391 adolescents (59.9 % female). Latent profiles involving the problematic behaviors of delinquency, depressive symptoms, substance use, sexual activity, disordered eating behaviors, and bullying were then assessed for concurrent relationships with the Five Cs of PYD: Competence, Confidence, Character, Caring, and Connection. We found six latent profiles, based primarily on mental health, aggression, and alcohol use, with significant differences in Confidence levels among many of the profiles, as well as some differences in the four other Cs. We discuss directions for future research and implications for application to youth policies and programs.  相似文献

Peer violence, peer sexual harassment and abuse, and staff abuse experienced by boys and girls in juvenile correctional facilities are compared with those experienced by peers in schools in the community. Responses of 360 youths in 20 gender-separated correctional facilities in Israel to a questionnaire tapping these forms of mistreatment were compared with those of 7,012 students in a representative sample of Israeli junior high and high schools. Victimization was reported more frequently by those in correctional facilities than by those in schools. However, some of the more prevalent forms of violence and abuse were reported with equal frequency in both settings, and some more frequently in schools. Despite being victimized more frequently, those in the correctional facilities tended to view their victimization as a significantly less serious problem than those in the schools and to rate the staff as doing a better job of dealing with the problem.  相似文献

Experiences of depression, anxiety, and peer victimization have each been found to predict one another, and to predict negative outcomes in the domains of school connectedness, social functioning, quality of life, and physical health. However, the common co-occurrence of depression, anxiety, and peer victimization experiences has made it difficult to disentangle their unique roles in these associations. The present study thus sought to characterize the precise nature of the bidirectional relationships between depressive symptoms, anxiety, and victimization over time, and to examine their unique sequelae during the transition from childhood to early adolescence. Longitudinal multi-informant (child-reported, parent-reported, and teacher-reported) data from a nationally representative sample were analyzed using path analysis when the study child was aged 10–11 (n=?4169; Mage?=?10.3; 48.8% female) and aged 12–13 (n=?3956; Mage?=?12.4; 48.2% female). Depressive symptoms, anxiety, and peer victimization had small but significant unique bidirectional relationships. All three constructs also uniquely and prospectively predicted poorer life functioning across all domains examined. These results demonstrate that current interventions should broaden their scope to simultaneously target depression, anxiety, and peer victimization, as each of these experiences independently act as additive risk factors for subsequent negative outcomes.
