Teenagers commonly use cannabis. Expectancies related to the effects of cannabis play an important role in its consumption and are frequently measured with the Marijuana Effect Expectancies Questionnaire (MEEQ). This study aims to assess the psychometric properties (factor structure, internal consistency reliability, criterion validity) of the French MEEQ. A sample of 1,343 non-clinical teenagers (14-18 years) were recruited to answer a self-report questionnaire; 877 of them responded twice (one-year interval). A four-factor structure was obtained: Cognitive Impairment and Negative, Relaxation and Social Facilitation, Perceptual Enhancement and Craving and Negative Behavioral Effect Expectancies. It is concluded that the French MEEQ constitutes an appropriate tool to measure cannabis effect expectancies among adolescents.

在非临床讲法语的青少年样本中验证大麻效应预期问卷（MEEQ）。

青少年通常使用大麻。与大麻影响有关的预期在其消费中起着重要作用，并经常通过大麻影响预期调查表（MEEQ）进行衡量。这项研究旨在评估法国MEEQ的心理测量特性（因素结构，内部一致性信度，标准效度）。收集了1343名非临床青少年（14-18岁）的样本来回答自我报告调查表；他们中的877位回答了两次（间隔一年）。获得了四因素结构：认知障碍和负面，放松和社会便利，知觉增强和渴望以及负面行为影响预期。结论是，法国的MEEQ是衡量青少年大麻效果期望值的适当工具。
