Most studies of decisions to curtail alcohol consumption reflect experiences of abusing drinkers. An exploratory sequential research design is used to explore the applicability of this research to the experience of nonabusing drinkers advised to curtail alcohol consumption after a hepatitis C diagnosis. A qualitative component identified 17 new decision factors not reflected in an inventory of factors based on synthesis of existing scales. Qualitative data were triangulated by supplementing semistructured interviews with Internet postings. A quantitative component estimated prevalence and association with current drinking of these new decision factors. Patients who quit drinking tended to attribute postdiagnosis drinking to occasional triggers, whereas patients who were still drinking were more likely to endorse rationales not tied to specific triggers.
