Persons with co-occurring Axis I mental disorders and substance use disorders often experience multiple negative consequences as a result of their substance use. Because no existing measure adequately assesses these population-specific problems, we developed the Problems Assessment for Substance Using Psychiatric Patients (PASUPP). This paper describes the scale development and factor structure, and provides initial reliability and validity evidence for the PASUPP.
An initial pool of 54 items was assembled by reviewing existing measures for relevant items and generating new items. Then, 239 patients (90% male, 61% White) with documented Axis I psychiatric and current substance use disorders rated the lifetime and last 3-month occurrence of each problem, and completed additional measures of substance use and related functioning.
Lifetime endorsements ranged from 31 to 95%, whereas 3-month endorsements ranged from 24 to 78%. Item analyses reduced the set to 50 items. The PASUPP is internally consistent (alpha = 0.97) and unidimensional. Scale validity was suggested by moderate correlation with other measures of substance problem severity.
Promising psychometric properties are reported for a population-specific measure of substance use problems. Such a measure could be useful for initial assessments and outcome evaluations with substance using psychiatric patients.
患有共病的轴I精神障碍和物质使用障碍的人，往往因其物质使用而经历多种负面后果。由于现有的测量方法都无法充分评估这些特定人群的问题，我们开发了物质使用精神病患者问题评估量表（PASUPP）。本文描述了该量表的开发和因子结构，并为PASUPP提供了初步的信度和效度证据。
通过回顾相关项目的现有测量方法并生成新项目，初步收集了54个项目。然后，239名有记录的轴I精神疾病和当前物质使用障碍患者（90%为男性，61%为白人）对每个问题的终生发生情况和过去3个月的发生情况进行了评分，并完成了物质使用及相关功能的其他测量。
终生认可率在31%至95%之间，而3个月认可率在24%至78%之间。项目分析将项目集减少到50个。PASUPP具有内部一致性（α=0.97）且为单维量表。与其他物质问题严重程度测量方法的中度相关性表明了量表的效度。
报告了一种针对特定人群的物质使用问题测量方法具有良好的心理测量学特性。这样一种测量方法可能有助于对物质使用精神病患者进行初始评估和结果评估。
