宾夕法尼亚酒精渴求量表(PACS)的信度及效度研究

The reliability and validity of Penn Alcohol Craving Scale(PACS).

目的对宾夕法尼亚酒精渴求量表的信度和效度进行测试。方法选取200例符合ICD-10中酒依赖综合症的诊断标准的患者,进行宾夕法尼亚酒精渴求量表评测,对所获资料进行因素分析和信度及效度检验。结果①Cronbach’sα系数为0.97;分半信度为0.88,表明本量表具有较好的信度。②因素分析显示单一主成分87.82(;与VAS的相容效度0.89;量表总分与各项目分内部相关系数r在0.77-0.92,表明量表具有较好的效度。结论宾夕法尼亚酒精渴求量表具有较好的信度和效度,是一种较好的对酒精渴求度的评测工具,适合我国临床应用。

Objective To investigate the reliability and validity of Penn Alcohol Craving Scale （PACS） . Methods A total of 200 patients met with the criteria of ICD - 10 for alcohol dependence were evaluated with PACS. Results （1） Cronbach＇ s α coefficients was 0.97 and the split - half reliability was 0.88. These results proved the PACS had good reliability. （2） One factor was extracted and the cumulative variance was 87.82 %. The congruent validity between PACS and VAS was 0.89. The correlation coefficients between the total inventory and every item＇ of PACS were from 0.77 to 0. 92. These results proved the PACS had good validity. Conclusion The PACS has good reliability and validity. There- fore PACS is a useful tool for assessing the alcohol dependence patients in Chinese region.
