The purpose of this study is to compare demographic and clinical differences across classes of substances among clients recruited into an effectiveness trial of the Therapeutic Education System (TES), an efficacious, web-based version of the Community Reinforcement Approach. Between June 2010-August 2011, clients were recruited from 10 outpatient drug treatment programs within NIDA's Clinical Trials Network (as part of protocol CTN-0044). Participants completed a brief eligibility screen followed by baseline assessment and randomization. Inclusion criteria were broad, though those receiving opioid replacement medication or those who had not used illicit substances in the prior 30 days were excluded. The randomized sample (n=507) was 38% female, an average of 41.5 years old, with varied primary substances of abuse (marijuana 23%; alcohol 21%; opioids 21%; cocaine 20%; stimulants 11%; other 5%). No differences by substance were detected on the Brief Symptom Inventory somatization or anxiety subscales; however depression scores differed (p=.02). Differences in frequency of internet use was also found (p=.03). Primary marijuana (58%) and alcohol users (55%) reported daily internet use more than cocaine (35%), stimulant (38%), and opioid users (46%).

Conclusions: This study was successful in recruiting a diverse, treatment-seeking sample. Clinical differences across primary substance of abuse have implications for treatment engagement and planning, as well as overall trial outcomes. (Poster, PDF, English, 2012)
