本研究探讨了预期的后果停止或减少大麻使用的初步发展和心理测量验证的措施，大麻停止预期。46项大麻戒断期望问卷（MCEQ）最初是根据94名参与者对停止和减少大麻使用的预期结果的自由回答的内容效度分析开发的。随后对151名非寻求治疗的常规大麻使用者进行了封闭式MCEQ（使用前60天的M = 64.7%，SD = 25.1%;法师= 21.4，SD = 3.96; 38.4%女性）。探索性因素分析确定了6个MCEQ因素，占方差的61%，这些因素与以下方面的预期改善有关：1）表现/动机，2）权威问题，3）人际功能，以及4）情绪状态和5）有趣体验的预期恶化，6）停止/减少大麻使用的食欲/体重变化。全量表项目的内部一致性良好（α = 0.86），所有因素的一致性均为中等偏高（α = 0.60 - 0.89）。MCEQ项目表现出良好的同步有效性与关键措施和增量关联的变化指数（先前的历史停止/减少尝试，减少的好处，改变的重要性），超越大麻使用预期的影响。这些数据为MCEQ提供了初步支持，并表明它与大麻使用者的减少/停止决定密切相关。MCEQ可用于临床，以加强现有的行为治疗和动机干预问题大麻的使用。
The present research examines anticipated consequences of ceasing or reducing marijuana use with initial development and psychometric validation of a measure of marijuana cessation expectancies. The 46-item Marijuana Cessation Expectancies Questionnaire (MCEQ) was initially developed from the content validity analysis of free responses about expected outcomes of stopping and decreasing marijuana use generated by 94 participants. The closed-ended MCEQ was subsequently administered to 151 non-treatment seeking regular marijuana users (used on M = 64.7% of the prior 60 days, SD = 25.1%; Mage = 21.4, SD = 3.96; 38.4% female). Exploratory factor analyses identified six MCEQ factors that accounted for 61% of variance, which were related to expected improvement in: 1) performance/motivation, 2) problems with authority, and 3) interpersonal functioning, and expected worsening of 4) mood states and 5) fun experiences, and 6) changes in appetite/weight from cessation/reduction of marijuana use. Internal consistency of full scale items was good (α = .86) and moderate to high for all factors (α’s =.60 – .89). The MCEQ items showed good concurrent validity with key measures and incremental associations with change indices (prior history of cessation/reduction attempt, benefits of reduction, importance of change), beyond the effects of marijuana use expectancies. These data provide initial support for the MCEQ and suggest it is closely linked to reduction/cessation decisions in marijuana users. MCEQ may be used clinically to enhance existing behavioral treatments and motivational interventions for problem marijuana use.
