Brief summary

The purpose of the current study is to evaluate the preliminary efficacy of the Therapeutic Education System-Native Version (TES-NAV) (an efficacious web-delivered psychosocial intervention for substance use disorders adapted with American Indians/Alaska Natives \[AI/AN\]) to determine whether a future large-scale effectiveness trial is warranted. Specifically, a randomized controlled trial among urban AI/AN (N=80) attending outpatient addiction treatment services will be conducted to (1) estimate preliminary effect size of 12 weeks of TES-NAV on substance use disorder outcomes; (2) explore relevant moderators of TES-NAV outcomes; and (3) assess cultural factors that may correspond to variation in outcome.
