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.
这项小规模研究旨在检验使用基于代金券的强化疗法（VBRT）作为精神分裂症患者可卡因滥用治疗方式的可行性。在VBRT干预期间，三名被诊断为精神分裂症的患者的可卡因使用量有所减少。有趣的是，所有的戒断都发生在干预的前半段。这段早期的清醒期可能代表了一个具有临床相关性的机会窗口，在此期间强化心理社会或社会工作干预可能有更大的成功机会。
