Daily support seeking as coping strategy in dual-smoker couples attempting to quit.

Objective: Smoking cessation is a stressful event and lapses are frequent. The dynamic model of relapse has been criticized for not integrating interpersonal factors as phasic influences. Seeking social support, as a coping strategy to deal with cravings, may help to refrain from smoking.

Design: Overall, 83 heterosexual dual-smoker couples reported on their craving, the extent of seeking social support from one's partner regarding smoking cessation, and their number of cigarettes smoked in smartphone-based end-of-day diaries, from a joint self-set quit date on across 22 consecutive days.

Main Outcome Measure: Number of cigarettes smoked.

Results: Multilevel analyses indicated that on days with higher-than-average levels of craving, male and female smokers reported more cigarettes smoked. Higher-than-usual support seeking was related to fewer cigarettes smoked that same day. For women only, we found a within-person interaction between craving and support seeking on smoking. On days with higher-than-average support-seeking, the effect of craving on smoking was attenuated.

Conclusion: Findings confirm the relevance of interpersonal processes in the relapse process, such as support seeking as coping behavior. Further, as a 'first act' in initiating supportive interactions, support seeking is an important piece in the social support process and a promising target for interventions.
