OBJECTIVE This study collected in-depth treatment satisfaction and effectiveness data to provide insight into the mechanisms of behavior change and to identify aspects of a text message- delivered treatment for cannabis use disorder that could be improved. METHODS Data were collected via a web-based survey from 30 young adults (ages 18-25) who were recent participants in a randomized controlled trial of Peer Network Counseling-txt (PNC- txt), a text message treatment for cannabis use disorder. The survey assessed reactions to the text-delivered treatment, changes in cannabis use, reactions to the peer-focused components, and feedback about improvements to the treatment. RESULTS Nearly all (93%) respondents found PNC-txt to be helpful to their treatment. The majority of the sample (63%) reported that PNC-txt heightened awareness of their cannabis use, and 40% reported a better understanding of problematic use. Fifty percent reported that they use less cannabis than they did prior to the intervention. Seventy percent of respondents stated that it was helpful to answer questions about their close friend group and nearly one- quarter of participants decreased the amount of time spent with "unhealthy" friends. Approximately 85% indicated that thinking about their peer network helped them meet goals of stopping, reducing, or better managing their cannabis use. CONCLUSIONS These findings provide insight into the acceptability of the text-delivered treatment platform and potential mechanisms of behavior change for PNC-txt. The participants provided positive feedback about the treatment and indicated that it helped reduce their cannabis use. Given the acceptability and promising efficacy of PNC-txt, continued research is warranted, particularly with adolescents and with larger samples.
