Perceived partner responsiveness predicts smoking cessation in single-smoker couples

INTRODUCTION

Romantic partners are crucial to successful smoking cessation, but the mechanisms by which partners influence cessation is unclear. Research in this area has focused heavily on partner smoking status and support for quitting, but partner influence may not be limited to these two constructs. The current study examines the perceived responsiveness of the partner (i.e., the perception that the partner understands, approves of, and supports the self) as a predictor of smoking cessation in unassisted quitters, independent of smoking-specific support for quitting and more general relationship satisfaction.

METHODS

Data were taken from a sample of smokers (N = 62) in relationships with never/former smokers (i.e., members of single-smoker couples) who completed a 21-day ecological momentary assessment study during an unassisted quit attempt. Measures of perceived responsiveness, support for quitting, and relationship satisfaction obtained at baseline were used to predict smoking outcomes over the course of the study.

RESULTS

Consistent with our predictions, perceived responsiveness emerged as a significant predictor of smoking cessation over and above the effects of support for quitting and relationship satisfaction. Support for quitting only predicted self-reported relapse. Unexpectedly, once perceived responsiveness was considered, greater relationship satisfaction was associated with poorer smoking outcomes.

CONCLUSIONS

The current research suggests that perceived responsiveness is a more effective resource for smoking cessation than support specifically for quitting. These findings extend previous research by demonstrating that perceived responsiveness represents a distinct construct from smoking-specific support or relationship satisfaction, and that it is important for smokers during a quit attempt.

A response surface analysis of expected and received support for smoking cessation: Expectancy violations predict greater relapse

People attempting to stop smoking cigarettes (quitters) hold expectations about the extent to which their partner will provide helpful support during a quit attempt. However, these expectations may not align with their perceptions of the helpfulness of the support they receive. We examine expected and received helpful support during a quit attempt. We hypothesized that receiving less helpful support than expected (i.e., creating an expectancy violation) would be associated with the greatest return to smoking. Sixty-two quitters completed a 21-day ecological momentary assessment (EMA) study. They reported expected support at baseline and support receipt and smoking during the EMA phase. At follow-up, they completed an expelled breath carbon monoxide test. Analyses using polynomial generalized linear models with response surface analysis indicated that smoking outcomes depended on the joint influence of expected and received helpful support. As hypothesized, when quitters expected more helpful support than they received, they were more likely to smoke in the first 24h and the last seven days of the EMA, and they provided higher carbon monoxide readings at follow-up. These results are consistent with an expectancy violation explanation: quitters are more likely to smoke when they perceive their partner has failed to provide support that is as helpful as expected. Given the importance of support for smoking cessation, many researchers have attempted to experimentally increase provision of support. The current findings suggest that partner support interventions might backfire if the quitter is led to expect more helpful support than the partner is able to provide.
