背景：结果预期在物质使用障碍的病因、评估和治疗中是一个关键的认知结构。研究和临床需要在大麻使用者的临床样本中验证大麻预期测量。方法：采用探索性大麻期望问卷（CEQ） （n = 501，平均年龄27.45岁）。（78%为男性）和验证性（n = 505，平均年龄27.69岁，78%为男性）对参加门诊大麻治疗项目的两个独立样本的大麻使用者进行因素分析。临床评估每周大麻消费量，患者完成大麻依赖严重程度量表（SDS-C）和一般健康问卷（GHQ-28）。结果：确定了消极大麻预期和积极大麻预期两个因素。这些为数据提供了可靠的统计和概念匹配。内部信度很高。消极的期望与更严重的依赖程度相关（由SDS测量），积极的期望与更高的消耗相关。在所有四个GHQ-28量表（躯体关注、焦虑、社交功能障碍和抑郁）中，积极和消极期望的相互作用始终与自我报告的功能显著相关。具体来说，在高积极大麻预期的背景下，更高的消极预期预示着更严重的功能受损。相比之下，在对大麻的积极预期较低的情况下，较高的消极预期预示着更好的功能。结论：CEQ是第一个大麻预期措施在治疗大麻使用者样本中得到验证。消极和积极的大麻预期域与消费、依赖严重程度和自我报告的心理健康功能有独特的关联。爱思唯尔爱尔兰有限公司版权所有版权所有。
Background: Outcome expectancies are a key cognitive construct in the etiology, assessment and treatment of Substance Use Disorders. There is a research and clinical need for a cannabis expectancy measure validated in a clinical sample of cannabis users.Method: The Cannabis Expectancy Questionnaire (CEQ) was subjected to exploratory (n = 501, mean age 27.45. 78% male) and confirmatory (n = 505, mean age 27.69, 78% male) factor analysis in two separate samples of cannabis users attending an outpatient cannabis treatment program. Weekly cannabis consumption was clinically assessed and patients completed the Severity of Dependence Scale-Cannabis (SDS-C) and the General Health Questionnaire (GHQ-28).Results: Two factors representing Negative Cannabis Expectancies and Positive Cannabis Expectancies were identified. These provided a robust statistical and conceptual fit for the data. Internal reliabilities were high. Negative expectancies were associated with greater dependence severity (as measured by the SDS) and positive expectancies with higher consumption. The interaction of positive and negative expectancies was consistently significantly associated with self-reported functioning across all four GHQ-28 scales (Somatic Concerns, Anxiety, Social Dysfunction and Depression). Specifically, within the context of high positive cannabis expectancy, higher negative expectancy was predictive of more impaired functioning. By contrast, within the context of low positive cannabis expectancy, higher negative expectancy was predictive of better functioning.Conclusions: The CEQ is the first cannabis expectancy measure to be validated in a sample of cannabis users in treatment. Negative and positive cannabis expectancy domains were uniquely associated with consumption, dependence severity and self-reported mental health functioning.
