Problem: Ariss and Fairbairn (2020) completed a meta-analysis of family-involved treatments that condensed data from 2,115 adolescents and adults across 16 independent trials. They calculated a small effect size that endured up to 12-18 months post-treatment and translated to a 5.7% reduction in SU frequency-the equivalent of approximately three fewer weeks per year of SU. They also found that family-involved treatment showed consistent impacts across client age, other characteristics, and treatment models. Moreover, both family and couple therapy produce benefits for SUD whether they are delivered as the exclusive treatment or as part of a multicomponent SUD treatment program (Hogue et al., in press).
