High psychiatric symptom severity is a moderator of substance abuse treatment outcomes among women in single vs. mixed gender group treatment.
OBJECTIVE
This exploratory study examined psychiatric symptom severity as a moderator of outcomes among women receiving either the Women's Recovery Group (WRG), a new manualized group treatment for substance use disorders combining single-gender group composition and women-focused content, or Group Drug Counseling (GDC), an empirically supported mixed-gender group treatment.


METHODS
We used a mixed model analysis of variance.


RESULTS
We found a significant 3-way interaction effect of treatment condition, time, and baseline Brief Symptom Inventory scores as well as Beck Depression Inventory scores.


CONCLUSIONS
Single-gender group treatment may confer added benefit for women with substance abuse and high psychiatric symptom severity than mixed-gender treatment.
