Empowered to stop smoking: The impact of a SDT smoking cessation intervention on economically disadvantaged whites and blacks

Abstract

1012 Background: Few studies have examined the potential influence of an empowering Self Determination Theory (SDT) intervention on reducing smoking behaviors and outcomes for Whites and Blacks. Objectives: To determine if empowerment to stop smoking is associated with smoking outcomes in Whites and Blacks, and to examine if empowerment to stop smoking improved under the SDT Intervention vs. Usual Care conditions. Methods: A longitudinal randomized trial study was conducted to examine the effect of a SDT and health behavior change intervention for tobacco cessation among adult smokers. Participants were randomized into the SDT Intervention or the Usual Care condition. The present study includes data from a sample of 821 Whites and 177 Blacks who completed anonymous surveys at 1, 6, and 18-months intervals on empowerment to stop smoking (Perceived Competence Scale, Treatment Self-Regulation Questionnaire), demographics, and smoking behaviors. Results: Stepwise logistic regressions showed that empowerment to stop smoking was associated with quitting smoking at 1, 6, and 18 month follow-up for both treatment conditions. At one month, participants in the SDT Intervention with the highest levels of empowerment were 6.3 times more likely to quit smoking as compared with those in the usual care condition who were only 3.15 times as likely to quit smoking. Similar findings were found at 6 months and at 18 months (6- month SDT Intervention Empowerment High: (OR = 8.66, 95% C.I. 4.6, 16.3); 6 month Usual Care Empowerment High: (OR = 3.10, 95% C.I. 1.4, 7.0); 18- month SDT Intervention Empowerment High: (OR = 4.10, 95% C.I. 2.2, 7.5); 18 month Usual Care Empowerment High: (OR = 3.11, 95% C.I. 1.3, 7.7). In the SDT Intervention at 6 months being Black increased successful quitting by 2.4 times. Conclusions: Findings indicate that at each time-point the SDT Intervention empowered more participants to stop smoking than usual care alone. Findings also suggest that Blacks may increase their ability to stop smoking in the SDT Intervention condition. These preliminary findings highlight the need to further investigate the possible roles of empowerment interventions in smoking cessation among Whites and Blacks, especially cancer patients.
