The high prevalence rates of cannabis use in adolescents and its early onset constitutes a major public health problem, raising the need for its early detection. The availability of validated tools to analyze early cannabis use is essential to detect problematic use at an early age. The Cannabis Abuse Screening Test (CAST) (Legleye et al., 2007) is widely applied in Europe; however, the CAST cut-off scores vary according to the setting, the screening objective, and the correction version (CAST-f or CAST-b), creating therefore confusion in its application. Moreover, the psychometric properties of the CAST as a tool for detecting problematic cannabis use are understudied. To fill this gap, such psychometric properties have been analyzed in a sample of Spanish adolescents while using different cut-off scores for CAST-f and CAST-b. Based on our findings, the optimal cut-off scores are 2 points for CAST-b and 4 points for CAST-f. The internal reliability of CAST-f (α = 0.83) and CAST-b (KR-20 = 0.80) are satisfactory. Factorial analysis suggested the assumption of a one-dimension model. The CAST seems to be a valid and reliable tool for early screening of problematic cannabis use in Spanish adolescents.
青少年大麻使用的高发率及其早期发病构成了一个主要的公共卫生问题,这就需要尽早发现。为了在早期发现有问题的使用情况,需要有经过验证的工具来分析早期的大麻使用情况。大麻滥用筛查测试(CAST)(Legleye 等人,2007 年)在欧洲被广泛应用;然而,CAST 的截断分数因设置、筛查目的和校正版本(CAST-f 或 CAST-b)而异,因此在应用中造成混乱。此外,CAST 作为检测大麻使用问题的工具的心理测量特性研究不足。为了填补这一空白,我们在一个西班牙青少年样本中分析了 CAST 的这些心理测量特性,同时使用了 CAST-f 和 CAST-b 的不同截断分数。根据我们的发现,CAST-b 的最佳截断分数为 2 分,CAST-f 的最佳截断分数为 4 分。CAST-f(α=0.83)和 CAST-b(KR-20=0.80)的内部可靠性令人满意。因子分析表明,该模型假设为一维模型。CAST 似乎是一种有效和可靠的工具,可用于早期筛查西班牙青少年中存在问题的大麻使用情况。
