Assessing multiple outcomes for women with co-occurring disorders and trauma in a multi-site trial: a propensity score approach.
The current study assesses the ability of two promising propensity scoring methods to reduce selection bias in a set of secondary data from the women with co-occurring disorders and violence study (WCDVS), whose purpose was to evaluate the effect of integrated treatment for women with mental health, substance use, and trauma issues (N = 2,729). Weighting, the more successful method, is demonstrated in a re-analysis of 6- and 12-month WCDVS outcomes. In addition to demonstrating propensity score weighting, the current study increases confidence in earlier findings by considering multiple time points simultaneously and by controlling more completely for pre-treatment differences.
