Interactive associations between abstinence plans and romantic partner conflict and support with cigarette smoking

Abstract

BackgroundWhile most individuals who smoke cigarettes desire to quit, quit motivation can change daily and sustained abstinence is rarely achieved in quit attempts. Assessment of psychosocial factors that moderate associations between daily abstinence intentions and smoking behavior is necessary to inform effective cessation efforts. MethodsA secondary analysis was conducted using data from a 28-day ecological momentary assessment study among individuals who smoke and who were not actively planning a long-term quit attempt (N = 81 individuals; N = 1585 days). We examined main effect and interaction associations between primary predictors (daily abstinence plans and within- and between-person estimates of perceived romantic relationship conflict and support) and daily number of cigarettes smoked, as well as baseline emotion regulation difficulties as a moderator of these associations. ResultsSmoking was reduced on days with an abstinence plan (β=−0.57,p<.001), especially among individuals with lower average levels of conflict (plan × between-person conflict interaction: β=0.98, p < .001), and higher average levels of support (plan × between-person support interaction: β=0.26, p < .001). Additionally, smoking was increased on days when participants had higher levels of conflict than usual (β=0.07, p < .01), but only on days when participants did not have a plan (plan × within-person conflict interaction:β=-0.10, p < .05). Emotion regulation difficulties did not moderate any associations. ConclusionThis study adds to the literature on the influence of negative aspects of social experience on smoking behavior. Further, the present study underlines the importance of assessing the influence of both positive and negative aspects of – and within- and between-person differences in – social experiences.
