We examined these outcomes and related factors. Methods: Bivariate analysis using chi square and t-test assessed the following outcomes: substance abuse, arrests, health problems, emotional problems, social risk problems, and recovery environment risk using Global Appraisal of Individual Need data collected as part of a multi-site study examining drug use, recidivism, service utilization and treatment. ADTC clients from twelve sites were included (N=666 male, 915 female). Independent variables included: gender, race, age, years of education, income, partner status, employment, social support, traumatization, and traumagenic factors. Results: Social support was associated with a decreased likelihood of arrest (p< .033), substance abuse (p< .001), recovery environment risk (p< .001) and social risk index (p< .001). Victimization within the past year was associated with increased substance use (p< .001), social risk problems (p< .008), and recovery environment risk (p< .001). Employment within the past year was associated with decreased recovery environmental risk (p< .024) and substance use (p< .001). Female gender was associated with an increased likelihood of reduction in substance abuse (p< .038). Conclusions:Desirable ADTCoutcomes derive from: Social support related to 4 of 6 outcomes. Victimization history related to 3 of 6 outcomes. Employment related to 2 of 4 outcomes. Client victimization related to ADTC outcomes. Addressing victimization and employment appear important to improve outcomes, as supported by these findings. Future analyses will examine whether these findings are robust in a multivariate analysis, controlling for trauma-informed treatment as well as a rasch based outcome model to determine factors that affect multiple outcomes.
