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

Not Applicable

Completed

• Conditions: Smoking Cessation
• Interventions: Behavioral: Positive Psychotherapy; Behavioral: Standard smoking cessation counseling

• Registration Number: NCT02997657
• Lead Sponsor: Brown University

Brief Summary

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.

Primary Outcome Measures

Name	Time	Method
7-day Point Prevalence Smoking Abstinence at 52 Weeks	52 weeks	Self-reported smoking abstinence biochemically confirmed with CO and cotinine
7-day Point Prevalence Smoking Abstinence at 26 Weeks	26 weeks	Self-reported smoking abstinence biochemically confirmed with CO and cotinine
7-day Point Prevalence Smoking Abstinence at 12 Weeks	12 weeks	Self-reported smoking abstinence biochemically confirmed with CO and cotinine
Continuous Smoking Abstinence	52 weeks	Self-reported continuous abstinence from cigarette smoking from quit date through the 52-week follow-up biochemically confirmed at 12, 26, and 52 weeks

Secondary Outcome Measures

Name	Time	Method
Residual Attraction to Smoking	At end of treatment (4 weeks after quit date)	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.
Self-efficacy for Resisting Smoking	At end of treatment (4 weeks after quit date)	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.
Engagement in PPT-consistent Quitting Strategies	During treatment - weeks 1-4 after quit date	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.
