Social Support in a Worksite Smoking Intervention

Abstract

To better understand how social support operates in smoking cessation, three models of support were tested: main effect, stress-buffering, and indirect. Employees from 61 worksites received (a) self-help manuals (SH); (b) self-help manuals and incentives (I); or (c) self-help manuals, incentives, and social support groups (G). At 24 months, results suggest that the main effect model of social support was operating in this study. That is, social support had a direct influence on smoking cessation. The group intervention significantly enhanced positive partner support across all time points, and partner support facilitated quitting smoking. Higher levels of appraisal support also significantly predicted successful quitting. The beneficial effects of social support were sustained throughout the process of quitting and long-term maintenance.
