Shifts in momentary motivation to quit smoking based on experimental context and perceptions of motivational instability

Abstract

BackgroundSmoking quit intentions (i.e., plans or commitments to reduce smoking) are distinct from quit motivation (i.e., desire to quit). Motivation to quit is a dynamic avoidance motivational state, likely subject to frequent fluctuations and shifts based on environmental context, similar to craving (an approach motivational state). Moreover, people's perceptions of motivational instability may influence their momentary quit motivation and beliefs surrounding their abilities to manage the quit process successfully. MethodsIn the current study, smokers were recruited online. Baseline motivation to quit was examined along with perceptions of motivational instability. Participants who reported some interest in eventually quitting (n = 174; Mage = 45.29, SD = 14.81, 74.1% women) were randomly assigned to negative affect, cigarette or neutral cue conditions and then momentary motivation to quit was assessed, followed by a validated index of quit intentions. ResultsParticipants in the negative affect and cigarette cue conditions reported greater momentary motivation to quit than participants in the neutral condition (F = 3.73, p = .03), particularly for people who reported upfront that their motivation did not change from day-to-day (F = 3.97, p = .02). In addition, greater momentary quit motivation predicted stronger quit intentions (B = 0.66, p < .001). ConclusionFindings from this study suggest that motivation to quit is likely dynamic and influenced by context as well as by self-perceptions. Implications suggest that further efforts to separate motivation from intention may be useful in understanding smokers' desires and plans to quit smoking.
