Motivational Interviewing to Reduce Substance Use in Adolescents with Psychiatric Comorbidity.

Substance use among adolescents with one or more psychiatric disorders is a significant public health concern. In this study, 151 psychiatrically hospitalized adolescents, ages 13-17 with comorbid psychiatric and substance use disorders, were randomized to a two-session Motivational Interviewing intervention to reduce substance use plus treatment as usual (MI) vs. treatment as usual only (TAU).

Family and peer influences on tobacco use among adolescents with psychiatric disorders.

The purpose of this study was to examine family and peer influences on smoking behaviors among 239 (191 smokers; 48 nonsmokers) psychiatrically hospitalized adolescents. Participants were queried using scales to measure parental supervision and monitoring, parenting style, adolescent-parent communication, family conflict and relations with parents, and the importance placed on life goals. The results of this study are consistent with previous findings from general population studies.
