A randomized trial of culturally accommodated versus standard group treatment for Latina/o adolescents with substance use disorders: Posttreatment through 12-month outcomes.

ABSTRACT

OBJECTIVES: Latina/o adolescents are at particular risk for substance use disorders (SUDs) and effective treatments are needed. Some critics indicate that standard evidence-based treatments may not meet the needs of Latina/o adolescents and culturally accommodated treatments are needed; however, few comparative studies have been conducted to test this assumption. This randomized trial was designed to test a standard group-based version of a cognitive-behavioral treatment (S-CBT) against its culturally accommodated equivalent (A-CBT) for a sample of Latina/o adolescents with SUDs. METHOD: Seventy Latina/o adolescents were randomly assigned to 1 of 2 treatment conditions and followed over 4 posttreatment time points with the last at 12-months. Generalized longitudinal mixed models for count data were conducted to evaluate treatment differences across time for adolescent substance use. The cultural variables ethnic identity, acculturation, and familism were included in the analysis as potential moderators of treatment outcome. RESULTS: A significant difference was found at the 12-month follow-up in favor of the culturally accommodated treatment (d = .92, 95% confidence interval, CI [.43, 1.42]) and parental familism moderated treatment outcome (d = .60, 95% CI [.12, 1.08]). CONCLUSION: This is one of the first studies to demonstrate that a culturally accommodated treatment differentially improved outcomes compared with that of its standard equivalent for a sample of Latina/o adolescents with SUDs.
