本研究调查是否使用成瘾严重程度指数（ASI）在网络的市中心酒精和药物滥用诊所在非理想条件下将产生内部一致和有效的数据。在34个月的时间内收集了8，984份ASI评分样本。结构效度通过计算各分量表的内部一致性进行检验。使用相关矩阵评价综合评分和严重程度评分的收敛和发散效度。研究结果表明，ASI评分是内部一致和有效的，即使推荐的管理协议可能并不总是被忠实地按照可能是可取的。这种鲁棒性预示着ASI在在线临床环境中的使用。在类似的非理想条件下测试ASI给药的可靠性之前，以及在可以量化标准方案的允许偏差之前，应谨慎看待结果。(C)2000 Elsevier Science Inc.

This study investigated whether the use of the Addiction Severity Index (ASI) in a network of inner-city alcohol and drug abuse clinics under nonideal conditions would yield internally consistent and valid data. A sample of 8,984 ASI scores was collected over a 34-month period. Construct validity was examined by computing the internal consistency of all subscales. Convergent and divergent validity of composite scores and of severity ratings were evaluated using correlation matrices. Findings demonstrated that ASI scores were internally consistent and valid, even though the recommended administration protocol may not always have been followed as faithfully as might be desirable. This robustness bodes well for the use of the ASI in on-line clinical environments. Results should be viewed with caution until the reliability of ASI administration is tested under similar nonideal conditions and until permissible deviations from standard protocol can be quantified.
