Abstract:

This small-scale study was conducted to examine the feasibility of using voucher-based reinforcement therapy (VBRT) as a treatment modality for cocaine abuse among individuals with schizophrenia. Cocaine use was reduced in three individuals with a diagnosis of schizophrenia during a VBRT intervention. Interestingly, all of the abstinence occurred during the first half of the intervention. This early period of sobriety may represent a clinically relevant window of opportunity during which intensive psychosocial or social work interventions might have a greater chance for success.
