The goal of the present study was to examine the psychometric properties and factor structure of the Alcohol Craving Questionnaire (ACQ).
The German version of the ACQ was administered to a sample of 243 alcohol-dependent or alcohol-abusing subjects. A subgroup of the sample (n = 46) completed the German translation of the Obsessive Compulsive Drinking Scale (OCDS) and the ACQ a second time.
To validate the factor models, confirmatory factor analyses (CFA) were carried out. Examination of the psychometric properties of the ACQ included the analysis of the item characteristics to exclude non-sensitive items, an exploratory factor analysis of the remaining items and calculation of internal consistency, test-retest reliability and convergent validity.
Neither of the two models showed a satisfactory correspondence. An exploratory factor analysis of a revised version of the ACQ (ACQ-R), based on the psychometric properties of the items, revealed two stable factors ('urge and intention to drink alcohol' and 'reinforcement') with high internal consistency, test-retest reliability and convergent validity. The model fit was also excellent in the CFA.
The ACQ-R is a reliable and valid instrument to assess alcohol craving. However, the ACQ-R lacks items related to loss of control. Therefore a multi-dimensional assessment, e.g. the combination of the ACQ-R and the OCDS, is recommended.
本研究旨在检验酒精渴望问卷（ACQ）的心理测量特性和因子结构。
对243名酒精依赖或酒精滥用受试者的样本进行了ACQ德文版测试。样本中的一个亚组（n = 46）再次完成了强迫性饮酒量表（OCDS）德文版和ACQ的测试。
为验证因子模型，进行了验证性因子分析（CFA）。对ACQ心理测量特性的检验包括对项目特征进行分析以排除不敏感项目，对其余项目进行探索性因子分析以及计算内部一致性、重测信度和收敛效度。
两个模型均未显示出令人满意的拟合度。基于项目的心理测量特性对ACQ修订版（ACQ-R）进行的探索性因子分析揭示了两个稳定因子（“饮酒的冲动和意图”以及“强化”），具有高内部一致性、重测信度和收敛效度。在CFA中模型拟合也非常出色。
ACQ-R是评估酒精渴望的可靠有效工具。然而，ACQ-R缺乏与失控相关的项目。因此，建议进行多维评估，例如将ACQ-R与OCDS结合使用。
