The Cannabis abuse screening test (CAST) is a short test used for screening those with problematic cannabis use. Recently, its invariance toward age was tested in an Israeli sample of cannabis users, but this study had some sample and methodological limitations: it was conducted in a volunteer sample aged 18-40 and considered the CAST items as continuous variables, although they are based on 5-point Likert scales. We thus tested the CAST invariance toward age (15-24, 25-34, and 35-64 years old) using a French probabilistic sample of 1,351 past-year cannabis users aged 15-64 and using appropriate methods for categorical items and survey weights. Factors retained (non-recreational use and problems) were the same as those mentioned in previous studies. Scalar invariance held for the "problems" factor but only partial scalar invariance was supported for the "non-recreational use" factor. Caution is thus needed when the CAST score is compared across age groups.
大麻滥用筛查测试（CAST）是一种用于筛查有问题大麻使用者的简短测试。最近，在以色列大麻使用者样本中对其在年龄方面的不变性进行了测试，但这项研究存在一些样本和方法学上的局限性：它是在一个年龄在 18-40 岁的志愿者样本中进行的，并且将 CAST 项目视为连续变量，尽管它们基于 5 点李克特量表。因此，我们使用了一个年龄在 15-64 岁的 1351 名过去一年使用大麻的法国概率样本，并使用适用于分类项目和调查权重的适当方法，测试了 CAST 对年龄（15-24 岁、25-34 岁和 35-64 岁）的不变性。保留的因素（非娱乐性使用和问题）与之前研究中提到的相同。“问题”因素具有标量不变性，但仅支持“非娱乐性使用”因素的部分标量不变性。因此，在比较不同年龄组的 CAST 评分时需要谨慎。
