Conditions

Schizo Affective Disorder, Schizophrenia, Smoking Cessation

Brief summary

All participants will receive free weekly counseling (8- weeks) and free nicotine patches (10-weeks). They will complete assessment measures commonly used in smoking cessation studies. We hope to show that this treatment is feasible in this small pilot study before comparing it to a more established treatment in a future randomized clinical trial.

Detailed description

This study is a non-randomized trial of a new psychosocial treatment for smoking cessation (for smokers with schizophrenia) that is based on cognitive behavioral therapy for smoking cessation - a commonly used approach. Participants will receive free weekly counseling (8- weeks) and free nicotine patches (10-weeks). They will complete assessment measures commonly used in smoking cessation studies. We hope to show that this treatment is feasible in this small pilot study before comparing it to a more established treatment in a future randomized clinical trial.
