这个子项目是许多研究子项目中利用 资源由NIH/NCRR资助的中心拨款提供。子项目和 调查员(PI)可能从NIH的另一个来源获得了主要资金， 并因此可以在其他清晰的条目中表示。列出的机构是 该中心不一定是调查人员的机构。 需要检验的具体假设是：1)对患有大麻使用障碍的青少年实施基于凭单的强化疗法是可行的，并为青年和治疗师所接受；2)针对青少年的凭单强化疗法减少了在治疗期间和完成治疗时的大麻使用；以及3)对青少年实施基于凭单的强化疗法比没有强化的对照条件更能有效地减少大麻的使用。拟议的试验遵循国家药物滥用研究所(NIDA)制定的第一阶段初步研究指南(Rounaville等人，2001年)。第一阶段项目的目标是1)确定第二阶段项目是否适用于第一阶段项目中检查的治疗，以及2)如果是，提供支持第二阶段应用所需的必要程序、手册、措施和数据(例如，效果大小估计)。关于第二阶段项目适当性的决定意味着所产生的数据支持针对该疾病和/或旨在治疗的行为所检查的治疗的可行性和临床效用。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The specific hypotheses to be tested are 1) Implementation of Voucher Based Reinforcement Therapy (VBRT) for youth with Cannabis Use Disorder is feasible and acceptable for both youths and therapists; 2) VBRT for youth produces a reduction of cannabis use during and at the completion of treatment; and 3) VBRT reinforcement for youth enhances a superior reduction of cannabis use relative to the non-reinforcement control condition. The proposed trial follows the guidelines for a preliminary Stage I study developed by the National Institute of Drug Abuse (NIDA) (Rounsaville et al., 2001). The goals of a Stage I project are 1) to determine whether or not a Stage II project is indicated for the therapy examined in a Stage I project, and 2) if so, provide the necessary procedures, manuals, measures, and data needed to support a Stage II application (e.g., effect size estimates). Decision on appropriateness of Stage II project implies that the data generated supports the feasibility and clinical utility of the therapy examined for that condition, and/or behavior that it is designed to treat.
