Dual-smoker couples are a high-risk, and underserved population, facing unique challenges to quitting smoking. A distinguishing factor among this population of smokers is the influence of their romantic partner on smoking habits and their subsequent ability to facilitate or hinder cessation efforts. Yet, empirical evidence on the extent and significance of a smokers’ interpersonal environment remains relatively underdeveloped. The present research examines associations between close relationships and smoking behavior by conducting 5 studies that explore the social environments of current smokers (Chapter 2), examine the role of romantic partners as smoking cues (Chapter 3), and assess the mutual influence of relationship quality and support behaviors on individual abstinence (Chapter 4). Findings from this research will enhance outcomes for both dual and single-smoker couples by identifying couple-related triggers that can inform targeted interventions promoting cessation and minimizing negative effects on relationships. This work also broadens our understanding of the impact of romantic partners on goal pursuit.
