Confirmatory factor analysis was used to test the scale structure of the Addiction Severity Index (ASI) in a sample of 1,802 substance abusers (43% alcohol dependent) with a concurrent psychiatric disorder (46% with mood disorders). The fit of the original composite score model based on the work of P. L. McGahan, J. A. Griffith, R. Parente, and A. T. McLellan (1990) was compared with the evaluation indices (EIs) developed by A. I. Alterman et al. (1998). The 5-dimensional model based on the EIs was an overall better fit to the data. Internal consistency (Cronbach's alpha) for the EIs ranged from.66 (family domain) to.75 (legal domain). The 5 EIs were moderately correlated (rs =.42-.72) with the interviewer severity ratings from the ASI. Evaluation studies involving concurrent disordered substance abusers should use the EIs as summary measures of change.
验证性因素分析用于检验成瘾严重程度指数（ASI）在1802名药物滥用者样本中的量表结构，这些滥用者中有43%对酒精依赖，同时患有精神疾病（46%患有情绪障碍）。基于P. L. 麦加汉、J. A. 格里菲思、R. 帕伦特和A. T. 麦克莱伦（1990年）的研究成果构建的原始综合评分模型的拟合度，与A. I. 阿尔特曼等人（1998年）开发的评估指标（EI）进行了比较。基于EI的五维模型总体上对数据的拟合度更好。EI的内部一致性（克朗巴哈系数）范围为0.66（家庭领域）至0.75（法律领域）。这五个EI与ASI面谈者严重程度评分呈中度相关（相关系数r = 0.42 - 0.72）。涉及并发精神障碍药物滥用者的评估研究应使用EI作为变化的汇总指标。
