Summary
Positive psychotherapy for smoking cessation (PPT-S) significantly improved quit rates compared to standard treatment. This approach shows promise for helping individuals quit smoking, especially those with higher positive affect.
Area of Science:
- Psychiatry
- Behavioral Science
- Clinical Psychology
Background:
- Depression and low positive affect (PA) are linked to poor smoking cessation outcomes.
- Smoking cessation interventions focusing on PA may improve success rates.
Purpose of the Study:
- To pilot a randomized clinical trial comparing standard smoking cessation treatment (ST) with positive psychotherapy for smoking cessation (PPT-S).
Main Methods:
- Smokers received 8 weeks of nicotine replacement therapy plus either ST or PPT-S.
- Smoking abstinence was biochemically confirmed at 8, 16, and 26 weeks.
Main Results:
- Longitudinal analysis revealed significantly higher odds of abstinence with PPT-S versus ST (AOR=2.75, p=.046).
- PPT-S benefits were stronger for individuals with higher PA (OR=6.69, p=.03).
- Increased use of PPT-S strategies correlated with sustained abstinence rates.
Conclusions:
- This pilot trial indicates that incorporating positive psychotherapy into smoking cessation treatment holds significant promise.
- PPT-S may be a valuable addition to existing smoking cessation strategies.
