Examination of contingency payments to dually-diagnosed patients in a multi-faceted behavioral treatment

Contingency management (CM) may be a promising component of treatment to help dually-diagnosed patients reduce their substance use. However, most prior studies examining CM with these patients have not examined the relationships among patient variables and contingency rewards received. This study examined whether characteristics of dually-diagnosed patients were related to CM payments received in a multi-faceted program. Fifty-nine dually-diagnosed patients participated in a multimodal behavioral therapy for illicit substance use involving CM. Baseline demographic and clinical characteristics were examined as they related to receipt of payments. Demographic characteristics generally were not related to receipt of payments. Several clinical variables, including diagnosis of schizophrenia, current substance dependence, and co-morbid alcohol dependence were related to payment receipt. These results provide an important step toward understanding the characteristics of dually-diagnosed patients that predict their response to CM.
