Using a combination of classical test theory and Rasch item analysis, we developed a short scale designed to measure the effectiveness of mental health treatment across a wide range of mental health services and populations. Item development for the scale was guided by literature review and interviews with senior clinicians and with patients. Using 3 different samples consisting of inpatients, outpatients, and nonpatients, we reduced our initial item pool from 81 to 10 items. The 10-item scale had an alpha of .96 and showed strong correlations with commonly used measures of psychological well-being and distress. Our results suggest that the scale appears to measure a broad domain of psychological health. The scale appeared to lack ceiling and floor effects, and it discriminated between inpatients, outpatients, and nonpatients, suggesting the scale has excellent potential to be broadly responsive to a variety of treatment effects. In addition, the new scale proved to be sensitive to treatment changes in a sample of 20 psychiatric inpatients. Overall, the initial data suggest that we have developed a brief, sensitive outcome measure designed to have wide application across psychiatric and psychological treatments and populations.
我们结合经典测试理论和拉施克项目分析，开发了一个简短量表，旨在衡量广泛的心理健康服务和人群中心理健康治疗的效果。该量表的项目开发以文献综述以及对资深临床医生和患者的访谈为指导。我们使用了由住院患者、门诊患者和非患者组成的3个不同样本，将最初的项目库从81项减少到10项。这个10项量表的阿尔法系数为0.96，与常用的心理健康和痛苦测量方法显示出很强的相关性。我们的结果表明，该量表似乎能够测量广泛的心理健康领域。该量表似乎没有天花板效应和地板效应，并且能够区分住院患者、门诊患者和非患者，这表明该量表具有很好的潜力，能够广泛地反映各种治疗效果。此外，在20名精神科住院患者的样本中，新量表被证明对治疗变化敏感。总体而言，初步数据表明，我们开发了一种简短、敏感的结果测量方法，旨在广泛应用于精神科和心理治疗及人群。
