目的：本研究评估的心理测量学特性的15项酒精短问题指数（SIP）仪器和新构建的15项药物短问题指数（SIP-D）仪器在277个新进入的物质滥用患者。方法：SIP是从更长的50项饮酒者后果清单（DrInC）中衍生出来的，该清单旨在评估酒精使用的不良后果。SIP-D是通过在每个SIP项目中将术语“饮酒”替换为术语“药物使用”而构建的。采用3个月的召回间隔。结果：每个工具的因素分析揭示了类似的解决方案，只有一个主要因素占大多数的方差。非参数项目反应理论方法产生了相同的结果。SIP和SIP-D总分的内部一致性可靠性估计值分别为0.98和0.97。并行效度通过检查每个工具的总分与新修订的成瘾严重程度指数（ASI-Version 6）的最新汇总指数的相关性来证明：酒精、药物、医疗、经济、法律的、家庭/社会和精神问题。结论：这项研究是第一次确认SIP作为未嵌入DrInC的独立工具使用时的心理测量有效性。该研究还支持使用SIP-D作为药物使用不良后果的简要衡量标准。研究结果强烈支持这两种措施的一维结构。(J.酒精药物研究70：304-307，2009）
Objective: This study evaluated the psychometric properties of the 15-item alcohol Short Index of Problems (SIP) instrument and those of a newly constructed 15-item drug Short Index of Problems (SIP-D) instrument in 277 newly entered substance-abuse patients. Method: The SIP is derived from the longer, 50-item Drinker Inventory of Consequences (DrInC), which was designed to assess adverse consequences of alcohol use. The SIP-D was constructed by substituting the term "drug use" for the term "drinking" in each SIP item. A 3-month recall interval was employed. Results: Factor analyses of each of the instruments revealed similar solutions, with only one main factor accounting for the majority of variance. Nonparametric item response theory methods produced the same finding. Internal consistency reliability estimates for the SIP and SIP-D total scores were .98 and .97, respectively. Concurrent validity was demonstrated by examining the correlations of the total scores for each of the instruments with the recent summary indexes of the newly revised Addiction Severity Index (ASI-Version 6): alcohol, drug, medical, economic, legal, family/social, and psychiatric problems. Conclusions: This study is the first to confirm the psychometric validity of the SIP when used as an independent instrument unembedded within the DrInC. The study also supports the use of the SIP-D as a brief measure of adverse consequences of drug use. The findings strongly support the unidimensional structure of both measures. (J. Stud.
