Psychological, peer, and family influences on smoking among an adolescent psychiatric sample

Although much is known about adolescent cigarette use and initiation in community samples, less is known about these factors among adolescents in clinic-referred populations or those with severe psychopathology. Data were collected from 106 adolescents aged 12 to 15 years (M = 13.6, SD = 0.74) recruited from a psychiatric inpatient facility. Hierarchical logistic regressions assessed the relationship among psychological, peer, and family environment factors and smoking at baseline and 18 months posthospitalization. Conduct problem symptoms, friends' cigarette use, and friends' marijuana use were associated with greater odds of lifetime and current smoking at baseline but not at follow-up. After accounting for the significant effect of baseline use, greater family conflict predicted decreased odds of having initiated smoking at the 18-month follow-up. The period following inpatient psychiatric hospitalization may represent an important window for smoking cessation and prevention efforts targeting peer and family factors, especially for youth with externalizing problems.
