Positive Psychotherapy for Smoking Cessation Enhanced With Text Messaging: A Randomized Controlled Trial

Brown University271 enrolled

Overview

Positive Psychotherapy for Smoking Cessation (PPT-S) addresses an array of risk factors for poor smoking outcomes (low positive affect, depressive symptoms, and cynical cognitions), while also providing skills that may buffer against stress and negative affect. The overall objective of this project is to conduct a randomized controlled trial to test the efficacy of PPT-S, enhanced with text messaging, compared to a time-matched behavioral smoking cessation treatment. Participants in both treatment conditions will receive nicotine replacement therapy and a validated text-messaging intervention for smoking cessation that monitors progress in quitting smoking and extends smoking counseling outside of the individual face-to-face context.

Outcomes

Primary Outcomes

7-day Point Prevalence Smoking Abstinence at 12 Weeks

Self-reported smoking abstinence biochemically confirmed with CO and cotinine

Time frame: 12 weeks

7-day Point Prevalence Smoking Abstinence at 26 Weeks

Self-reported smoking abstinence biochemically confirmed with CO and cotinine

Time frame: 26 weeks

7-day Point Prevalence Smoking Abstinence at 52 Weeks

Self-reported smoking abstinence biochemically confirmed with CO and cotinine

Time frame: 52 weeks

Continuous Smoking Abstinence

Self-reported continuous abstinence from cigarette smoking from quit date through the 52-week follow-up biochemically confirmed at 12, 26, and 52 weeks

Time frame: 52 weeks

Secondary Outcomes

Engagement in PPT-consistent Quitting Strategies

Engaging in strategies consistent with the positive psychology exercises taught in the trial. Nine strategies are assessed on 1 to 5 scale with 5 reflecting greater use of the strategies. The total score is the average across the 9 item.

Time frame: During treatment - weeks 1-4 after quit date

Residual Attraction to Smoking

Self-report residual attraction to smoking. Three questions are dichotomized and any positive response indicating residual attraction to smoking is coded as a 1 with any having only negative responses is coded as 0 - no residual attraction.

Time frame: At end of treatment (4 weeks after quit date)

Self-efficacy for Resisting Smoking

Self-reported confidence in remaining abstinent from smoking. The 9-item scale uses a 1-5 response scale and the total score is the average of those 9 responses, where higher scores represent higher confidence in resisting smoking.

Time frame: At end of treatment (4 weeks after quit date)
