The present study assessed the factor structure, reliability, test retest, convergent validity, and predictive validity of the Obsessive Compulsive Cocaine Scale (OCCS), a newly developed questionnaire adapted from the Obsessive Compulsive Drinking Scale (OCDS). The questionnaire was administered to 189 cocaine-dependent individuals participating in two medication treatment trials for cocaine dependence. Confirmatory factor analysis of this measure revealed that it primarily assesses two factors, obsessions and compulsions. In addition, the data provided strong support for the internal consistency, test-retest reliability, predictive validity, and convergent validity of this two-factor measure. Overall, the data provide support for the psychometric strength of a modified version of the OCDS specifically designed to assess obsessive and compulsive cocaine use among those with cocaine dependence.
本研究评估了新开发的可卡因强迫量表（OCCS）的因子结构、信度、重测信度、聚合效度和预测效度，该问卷改编自强迫性饮酒量表（OCDS）。该问卷被用于 189 名可卡因依赖者，他们参与了两项可卡因依赖药物治疗试验。该测量方法的验证性因子分析表明，它主要评估两个因素，即强迫观念和强迫行为。此外，数据还强烈支持该双因素测量方法的内部一致性、重测信度、预测效度和聚合效度。总的来说，数据支持一种 OCDS 修正版本的心理测量学强度，该版本专门用于评估可卡因依赖者的强迫性和强迫性可卡因使用。
