Positive Psychotherapy for Smoking Cessation: A Pilot Randomized Controlled Trial
Mené auprès de 66 fumeurs, cet essai évalue, du point de vue du taux d'abstinence tabagique à 8, 16 et 26 semaines, l'intérêt d'incorporer des séances de "psychothérapie positive" dans un programme standard d'aide au sevrage tabagique comportant un traitement susbstitutif nicotinique
Objective : Greater depressive symptoms and low positive affect (PA) are associated with poor smoking cessation outcomes. Smoking cessation approaches that incorporate a focus on PA may benefit smokers trying to quit. The purpose of this study was to conduct a pilot randomized clinical trial to compare standard smoking cessation treatment (ST) to smoking cessation treatment that targets positive affect, termed positive psychotherapy for smoking cessation (PPT-S).
Method : Smokers who were seeking smoking cessation treatment were assigned by urn randomization to receive, along with 8 weeks of nicotine replacement therapy, either ST (n = 31) or PPT-S (n = 35). Seven-day point prevalence smoking abstinence was biochemically confirmed at 8, 16, and 26 weeks.
Results : Compared to ST, a greater percentage of participants in PPT-S were abstinent at 8 weeks, 16 weeks, and 26 weeks, but these differences were nonsignificant. In a more statistically powerful longitudinal model, participants in PPT-S had a significantly higher odds of abstinence (adjusted odds ratio = 2.75; 95% confidence interval [CI] = 1.02, 7.42, p = .046) across follow-ups compared to those in ST. The positive effect of PPT-S was stronger for those higher in PA (OR = 6.69, 95% CI [1.16, 38.47], p = .03). Greater use of PPT-S strategies during the initial 8 weeks of quitting was associated with a less steep decline in smoking abstinence rates over time (OR = 2.64, 95% CI [1.06, 6.56], p =.04).
Conclusion : This trial suggests substantial promise for incorporating PPT into smoking cessation treatment.
