Evaluation of an SMS Based Alcohol Intervention for Same Sex Attracted Women: A Randomized Controlled Trial to Examine Feasibility, Acceptability, and Efficacy.

Purpose: The purpose of this randomized controlled trial (Trial registration ID: redacted) was to examine the feasibility, acceptability, and efficacy of the Step One program, an SMS-based alcohol intervention for same-sex attracted women (SSAW).

Methods: Ninety-seven SSAW who scored ≥8 on the Alcohol Use Disorders Identification Test (AUDIT) were randomly allocated to receive the Step One program ( = 47; mean age = 36.79) or a weekly message containing a link to a website with health information and support services for LGBT individuals ( = 50; mean age = 34.08). Participants completed questionnaires on alcohol use, wellbeing, and help-seeking at baseline (T1), intervention completion (T2; 4 wk after baseline) and 12 wk post-intervention (T3). In addition, participants in the intervention condition completed feasibility and accessibility measures at T2, and a subsample ( = 10) was interviewed about acceptability at T3.

Results: Across conditions, participants significantly reduced their alcohol intake and improved their wellbeing and help-seeking over time. However, there were no significant differences between the intervention and control condition. Furthermore, frequency of help-seeking was low; only four intervention group participants and three control group participants began accessing support between T1 and T3. Overall, our findings indicate the intervention would benefit from revision prior to implementation.

Conclusions: Our approach was consistent with best practice in the development of an ecologically valid intervention; however, this intervention, in its current form, lacks the complexity desired by its users to optimally facilitate alcohol reduction among SSAW.
