Summary

The purpose of this research study is to better understand (1) why people gain weight when they quit smoking and (2) whether certain types of smoking cessation (i.e. quit smoking) counseling combined with the nicotine patch help people quit smoking and gain less weight.

Detailed description

This is a randomized clinical trial of the efficacy of a behavioral activation intervention to smoking cessation and to post-cessation weight gain (BAS+) plus transdermal nicotine (TN) compared to standard smoking cessation counseling (SC) plus TN in treatment-seeking smokers. After completing an Intake Visit (\~week -3), eligible smokers will be randomized (stratified by nicotine dependence, BMI and gender) to participate in 8 individual sessions of BAS+ or SC over a 10-week treatment period with two sessions prior to the target quit date (weeks -2, -1) and six sessions post-target quit date (TQD \[week 0\] and weeks 1, 2, 4, 6, and 8). Standard, 8-week; open-label TN will begin on the TQD. Moderators will be assessed pre-treatment. Mediating mechanisms will be assessed before, during, and at the end of treatment (EOT, week 8). Smoking will be assessed by self-report and biochemically confirmed (Carbon Monoxide \[CO\] \< 5) at all in-center visits after quitting, at EOT (week 8), and at the 12- and 26-week follow-ups. Weight will be assessed at these same time points. Food intake will be measured by three consecutive days of 24-hour food recalls at Baseline \[week -2\] and 4-, 8-, and 12- and 26-weeks post-TQD. Smoking cessation and post-cessation weight gain (PCWG) are the primary outcomes and food intake is a secondary outcome at 26-weeks post-TQD. Consistent with intent-to-treat (ITT) analyses, the investigators will measure smoking cessation and weight gain in the full sample at the 26-week follow-up, evaluating a smoking status by treatment interaction for the PCWG analysis.

Conditions

• Smoking Cessation
• Weight Loss

Interventions

Type	Name	Description
BEHAVIORAL	BAS+	The goal of the BAS+ is to maintain a level of overall reward after cessation by structuring and enhancing opportunities for reinforcement to: (1) ensure that not smoking is as reinforcing as smoking; and (2) prevent an over-reliance on food as a substitute reinforcer for smoking so that PCWG does not precipitate smoking relapse.
BEHAVIORAL	SC	Overeating and weight gain are common concerns reported during smoking cessation treatment. Per convention, SC will address these concerns through standard recommendations to consume low-calorie snack foods, drink water, eat nutritious meals, and exercise, but will not include skills to shape the use of these suggestions.
