This study investigated the predictive validity of a brief, five item version of the Competency Screening Test (CST). Subjects were 140 defendants admitted to the forensic unit of a state hospital for evaluation of competency to stand trial. Scores on the brief version of the CST were used to predict competency decisions made by a multidisciplinary treatment team. In addition, the predictive validity of the brief version was compared with that of the standard CST. Both versions of the test exhibited significant relationships with staff decisions. However, the reliability of the brief version was lower than that of the standard CST because of the smaller number of items involved. Although the brief CST should not provide the sole basis for a decision about competency, it may be a useful component of a comprehensive program of competency evaluation, particularly when a rapid, preliminary screening instrument is needed.
本研究调查了简易版五项能力筛查测试（CST）的预测效度。研究对象为140名被收治到一家州立医院法医科以评估受审能力的被告。简易版CST的得分被用于预测多学科治疗团队做出的能力判定。此外，还将简易版的预测效度与标准CST的预测效度进行了比较。两个版本的测试均与工作人员的判定呈现出显著相关性。然而，由于所涉项目数量较少，简易版的可靠性低于标准CST。尽管简易版CST不应作为能力判定的唯一依据，但它可能是全面能力评估计划的一个有用组成部分，尤其是在需要快速初步筛查工具时。
