Abstract

ABSTRACT: This mixed methods study aimed to evaluate the feasibility and preliminary efficacy of a fully automated, interactive smartphone-delivered intervention for smoking cessation among people living with HIV in Cambodia. We used the explanatory sequential design, with a pilot two-group single-blind randomized controlled trial ( N = 50) followed by in-depth interviews with all trial participants. In the trial, participants were randomized to Standard Care (SC) or Automated Messaging (AM) group. SC comprised brief advice to quit and self-help materials. AM consisted of the SC components plus a fully automated smartphone-based treatment program that involved interactive and tailored proactive messaging for 2 months. Results showed that the AM approach was highly feasible and efficacious. Feasibility was supported by high rates of treatment engagement (e.g., 81% of delivered messages and assessments were read or completed) and high retention (96%) through the 2-month follow-up. Biochemically verified point prevalence abstinence at follow-up was 40% for the AM group and 8% for the SC group (relative risk: 5.0, 95% confidence interval: 1.2, 20.5). Being able to avoid other smokers, having coping skills, and having social/familial support contributed to successful abstinence. The AM program has the potential for wide-scale implementation in Cambodia and other low-income countries.
