The cocaine craving questionnaire-brief (CCQ-Brief English) asks cocaine users to report their level of craving now. We constructed two brief scales of cocaine craving in a sample of 107 Spanish-speaking natives in treatment for cocaine abuse or dependence: the CCQ-Brief(Spanish) and the pictographic assessment of desire (PAD), which relies less on language. Principal component analyses yielded a one-component solution for the CCQ-Brief, explaining between 62% and 68% of the sample variability. Cronbach's alpha ranged from .92 to .94. The CCQ-Brief and the PAD were strongly correlated; effect sizes ranged from .42 to .68 in separate trials. Laboratory cue-exposure results showed that in both scales craving was higher upon presentation of cocaine-related rather than neutral pictorial stimuli. The CCQ-Brief and PAD are potentially valuable scales for evaluating cocaine craving.
可卡因渴望问卷-简明版（CCQ-Brief English）要求可卡因使用者报告他们现在的渴望程度。我们在 107 名西班牙语母语的可卡因滥用或依赖治疗患者中构建了两个可卡因渴望的简明量表：CCQ-Brief（西班牙语）和渴望的象形评估（PAD），后者对语言的依赖程度较低。主成分分析为 CCQ-Brief 提供了一个单成分解决方案，解释了样本变异性的 62%到 68%。克朗巴赫的阿尔法系数在.92 到.94 之间。CCQ-Brief 和 PAD 相关性很强；在单独的试验中，效应大小从.42 到.68 不等。实验室线索暴露结果表明，在两个量表中，呈现可卡因相关的图片刺激时的渴望程度高于呈现中性图片刺激时的渴望程度。CCQ-Brief 和 PAD 可能是评估可卡因渴望的有价值的量表。
