Smoking Cessation Treatment for Smokers With Obesity

The intervention will be implemented in 8-week group-based sessions and includes: 1) A Cognitive Behavioral Treatment (CBT) for smoking cessation with quit date occurring at sixth session. Patients will be asked to reduce their nicotine intake gradually (i.e., 20% each week); 2) A Weight Gain Prevention module (WGP) which will consist on providing CBT and Dialectical-Behavioral Therapy (DBT) techniques targeting weight stability and associated disordered eating, and 3) a Contingency Management procedure reinforcing smoking abstinence. This component will consist on providing vouchers to reinforce abstinence contingent on biochemical verification. The schedule will incorporate an increasing magnitude of reinforcement.

The intervention will be implemented in 8-week group-based sessions and will include only the first two components of the experimental intervention: 1) A Cognitive Behavioral Treatment (CBT) for smoking cessation with quit date occurring at sixth session. Patients will be asked to reduce their nicotine intake gradually (i.e., 20% each week); 2) A Weight Gain Prevention module (WGP) which will consist on providing CBT and Dialectical-Behavioral Therapy (DBT) techniques targeting weight stability and associated disordered eating.
