Reaching and Motivating Change in Teen Marijuana Smokers

描述（由申请人提供）： 在NIDA的行为疗法发展计划的主持下，要求提供资金来支持一项疗效试验，评估一项名为“青少年大麻检查”的干预措施，该措施针对的是不寻求治疗的青少年大麻使用者。这项拟议的研究是基于申请人在此干预下完成的早期1a和1b阶段研究。在西雅图地区的四所高中招募的300名吸食大麻的青少年（14-19岁）将参加试验。参与者将通过课堂上关于大麻的演讲或学校工作人员的推荐来招募。他们将首先评估大麻，酒精和其他药物的使用情况，以及相关的态度和目标。然后，参与者将被随机分配到三个条件之一。实验性干预是一个两阶段的动机增强治疗。一个个性化的反馈报告，包含信息的参与者的评估以及规范的比较数据，进行审查，与健康教育工作者采用动机访谈策略，旨在提高动机减少或停止使用大麻。与希望支持改变大麻使用的参与者讨论了改变和行为改变策略的具体目标。比较条件涉及两个教育会议，重点是大麻的健康和行为影响。第三个条件（延迟治疗控制）涉及最低限度的基线评估，三个月后进行重新评估访谈。那些被分配到这种情况下，然后将给予他们选择的积极治疗。在完成两次干预会议后，两次积极治疗的参与者将接受另外四次认知行为技能培训，重点是戒烟策略。所有参与者将在初次评估面谈后3个月和12个月进行重新评估。

DESCRIPTION (provided by applicant): Under the auspices of NIDA's Behavioral Therapies Development Program, funds are requested to support an efficacy trial evaluating an intervention called "The Teen Marijuana Check-Up" with non-treatment seeking adolescent marijuana users. This proposed research is based on earlier Stage 1a and 1b research completed by the applicants with this intervention. Three hundred adolescents who smoke marijuana (ages 14-19), recruited in four Seattle-area high schools, will be enrolled in the trial. Participants will be recruited either through in-class presentations focusing on marijuana or via referrals from school staff. They will first be assessed regarding use of marijuana, alcohol, and other drugs, as well as pertinent attitudes and goals. Participants will then be randomly assigned to one of three conditions. The experimental intervention is a two-session motivational enhancement treatment. A personalized feedback report, containing information from the participant's assessment as well as normative comparison data, is reviewed, with the Health Educator employing motivational interviewing strategies intended to enhance motivation for reduction or cessation of marijuana use. Specific goals for change and behavior change strategies are discussed with participants who wish support to change their marijuana use. The comparison condition involves two educational sessions focusing on the health and behavioral effects of marijuana. The third condition (delayed treatment control) involves a minimal baseline assessment followed three months later by a reassessment interview. Those assigned to this condition will then be given their choice of either active treatment. Following completion of their two intervention sessions, participants in the two active treatments will be offered an additional four sessions of cognitive-behavioral skills training in which the focus is strategies in quitting marijuana. All participants will be reassessed at 3 and 12 months following their initial assessment interviews.
