The Drug Abuse Screening Test (DAST) is a 28-item screening instrument developed by Skinner for clinical screening and treatment evaluation research in the substance abuse field. In a sample of 250 psychiatric patients drawn from four treatment programs, the DAST evidenced high internal consistency reliability and good item-total score correlations. A factor analysis of the DAST item correlation matrix revealed a predominantly unidimensional scale with the possibility of rotating five additional factors reflecting a continuum of drug abuse. The five factors were interpreted as (a) self-recognition of a drug problem, (b) serious social consequences of drug use, (c) help-seeking for drug abuse, (d) illegal drug-related activities, and (e) inability to control drug use. The diagnostic validity of the DAST in discriminating patients according to DSM-III Substance Abuse diagnostic criteria was high and a range of valid clinical DAST cutoff scores from 5/6 through 10/11 was identified. The DAST appears to be a valid measure of drug involvement and abuse in a psychiatric patient population, a finding of increasing clinical relevance.
药物滥用筛查测试（DAST）是斯金纳开发的一种包含28个条目的筛查工具，用于药物滥用领域的临床筛查和治疗评估研究。在从四个治疗项目中抽取的250名精神科患者样本中，DAST显示出较高的内部一致性信度和良好的项目与总分相关性。对DAST项目相关矩阵的因子分析显示，它主要是一个单维量表，有可能旋转出另外五个反映药物滥用连续体的因子。这五个因子被解释为：（a）对药物问题的自我认知，（b）药物使用的严重社会后果，（c）寻求药物滥用帮助，（d）与非法药物相关的活动，以及（e）无法控制药物使用。根据《精神疾病诊断与统计手册》第三版（DSM-III）物质滥用诊断标准，DAST在区分患者方面的诊断效度很高，并且确定了一系列有效的临床DAST临界分数，范围从5/6到10/11。DAST似乎是精神科患者群体中药物参与和滥用的有效测量工具，这一发现具有越来越高的临床相关性。
