Using a sample of HIV-infected heavy drinkers, this study evaluated whether effects of two alcohol interventions (Motivational Interviewing [MI] alone or supplemented with an interactive technological enhancement called Healthcall) varied according to acceptability of drinking in participants’ neighborhoods. Results suggested that the efficacy of MI alone differed according to neighborhood norms, with MI alone only demonstrating effects in more permissive neighborhoods. The efficacy of MI + HealthCall did not vary by neighborhood, suggesting more robust effects of this intervention on drinking reduction.
