RESUMEN
The aim of this study was to investigate characteristics that might enhance retention among adolescents attending outpatient alcohol and drug group therapy within a youth mental health setting. An important goal was to provide information for nurses and other clinicians who work with adolescents with coexisting substance use and mental health disorders. A retrospective file audit reviewed the files of 64 adolescents who attended a weekly alcohol and drug group between 2002 and 2004. Five characteristics were shown to have a significant impact on enhancing participant group retention. These were Maori and Pacific Island ethnicity, past or current legal charges, youth drug court (YDC) involvement, having a diagnosis of cannabis dependence, and a diagnosis of conduct disorder. Logistic regression found that YDC involvement on its own significantly predicted treatment retention. In an area of limited research, the findings from this study expand the literature on enhancing treatment retention for a vulnerable and hard-to-engage adolescent group with complex treatment needs, and highlight the need for further investigation of the potential role of the YDC. From a practice perspective, the findings support group therapy interventions as a cost-effective treatment modality for assisting adolescents with coexisting substance use and mental health issues, including those with conduct disorder and YDC involvement.
