Substance use prevalence rates among migrant and native adolescents in Europe: A systematic review.

Issues: Migrant adolescents show specific risk and protective factors associated with substance use, but the extent to which prevalence rates differ between migrant and native-born youth in Europe remains unclear. The present study aims to provide a comprehensive review of all available substance use prevalence studies on differences in substance use between migrant and native-born adolescents in Europe.

Approach: In this systematic review, PubMed, Medline and Pre-Medline, EMBASE and PsycINFO were searched for articles comparing substance use prevalence rates (tobacco, alcohol, illicit drugs) between migrant and native-born adolescents or young adults aged 11 to 29 years in European countries.

Reliable and clinically significant change based on the Health of the Nation Outcome Scales.

To evaluate treatment outcomes of individual patients based on clinician-rated instruments, the assessment of reliable and clinically significant change (RCSC) is essential. In heterogeneous samples, RCSC underestimates treatment outcome. Therefore, the Reliable Change Index (RCI) was adjusted by a stratification into subsamples.
