Although commonly assessed with unidimensional scales, craving has been suggested to be multifaceted and to have a complex relationship with drug use and relapse. This study assessed the consistency and predictive validity of unidimensional and multidimensional craving scales. At the beginning of a 12-week outpatient treatment trial, opiate users (n = 101) and cocaine users (n = 72) completed unidimensional visual analog scales (VASs) assessing "want," "need," and "craving" and multidimensional 14- and 45-item versions of the Cocaine Craving Questionnaire (CCQ) or Heroin Craving Questionnaire (HCQ). Spearman correlations between the VASs and the first-order factors from the 45-item CCQ/HCQ were .20-.40, suggesting that the two types of assessment were not redundant. Treatment dropout and in-treatment drug use were more frequently predicted by scores on the 14- or 45-item CCQ than by VAS ratings. Results suggest that the CCQ/HCQ and the 14-item CCQ provide information that unidimensional VASs do not.
尽管通常使用单维度量表进行评估，但渴望已被认为是多方面的，并且与药物使用和复发有着复杂的关系。本研究评估了单维度和多维度渴望量表的一致性和预测效度。在一项为期12周的门诊治疗试验开始时，阿片类药物使用者（n = 101）和可卡因使用者（n = 72）完成了评估“想要”“需要”和“渴望”的单维度视觉模拟量表（VAS），以及可卡因渴望问卷（CCQ）或海洛因渴望问卷（HCQ）的14项和45项多维度版本。VAS与45项CCQ/HCQ的一阶因子之间的斯皮尔曼相关性为0.20 - 0.40，这表明这两种评估类型并非冗余。与VAS评分相比，14项或45项CCQ的得分更能频繁预测治疗中断和治疗期间的药物使用情况。结果表明，CCQ/HCQ和14项CCQ提供了单维度VAS所没有的信息。
