Brief Summary

This study examines the use of contingent incentives to increase attendance at smoking cessation treatment sessions by smokers with schizophrenia and other psychoses who want to quit smoking.

Interventions

Contingency Management BEHAVIORAL

Participants draw from a fishbowl to obtain tokens when they attend a smoking cessation treatment session. The number of draws will be based upon attendance at consecutive sessions. Tokens include messages of encouragement ("Good job!") or VA canteen vouchers of varying monetary value.

Arm 1

Reward BEHAVIORAL

Participants receive set reward (VA canteen voucher) for each week of smoking cessation treatment they attend. The value of the reward will not change regardless of attendance at consecutive sessions.
