Aim: To compare the effects of emotion regulation strategies that target smoking-related thoughts on behavioural, affective and subjective correlates of smoking. Method: Seventy-five participants were sequentially allocated to cognitive defusion (n=25), reappraisal (n=25) or suppression (n=25) conditions and applied these strategies to thoughts associated with smoking during a cue-induced craving procedure in a single experimental session. Dependent variables included smoking behaviour, behavioural approach/avoidance bias, and subjective measures of experiential avoidance, cue-induced craving, and affect. Results: Defusion and reappraisal were associated with restraint in smoking behaviour in the immediate post-session period and a reduction in smoking at seven day follow-up compared to suppression. Benefits for smoking behaviour were associated with a reduction in craving in the reappraisal condition and a greater reduction in experiential avoidance in the defusion condition. Those in the suppression condition exhibited the strongest approach bias for smoking related cues but also rating the strategy as having lower credibility and treatment expectancy relative to the two other conditions. Conclusion: Defusion and reappraisal resulted in similar benefits in terms of smoking-related behavioural outcomes. However, defusion and reappraisal were associated with distinctive experiential and affective outcomes. The results are considered in the context of lower credibility and expectancy ratings in the suppression condition and discussed with reference to the development of Cognitive Therapy and Acceptance and Commitment Therapy for addiction-related disorders.
