Subjective well-being, personality, demographic variables, and American state differences in smoking prevalence.

INTRODUCTION: The present study was conducted to determine relations between smoking prevalence, subjective well-being, and the Big Five personality variables at the American state level.
METHOD: State smoking prevalence was based on the responses of more than 350,000 adults interviewed in the Behavioral Risk Factor Surveillance System in 2008. Subjective well-being was based on the state-aggregated responses of 353,039 adults to the Gallup-Healthways Well-Being Index phone interviews during 2008. Big Five variables were based on the state-aggregated responses of 619,397 persons to an Internet survey between 1999 and 2005, which included the 44-item Big Five Inventory.
RESULTS: Well-being and smoking prevalence were negatively correlated and remained so when state Big Five, socioeconomic status (SES), White population percent, urban population percent, and median age were controlled in a partial correlation. Hierarchical and stepwise multiple regressions showed (a) that SES and neuroticism were the prime predictors of well-being, (b) that well-being was the prime predictor of smoking prevalence, and (c) that openness to experience was the sole personality or demographic variable to account for differences in smoking prevalence when well-being was controlled, and it explained very little of the remaining variance. DISCUSSION: Applied implications for state-tailored attempts to reduce smoking are briefly discussed, and suggestions for future research directions are put forward.
