目的：作者描述了马里兰州严重精神疾病患者康复评估（MARS）的发展，这是一种25项自我报告工具，用于测量严重精神疾病患者的康复情况，并报告了对其心理测量特性的研究。方法：具有重性精神疾病专业知识的博士级科学家编制了一套关于重性精神疾病患者康复过程的调查问卷。项目反映了药物滥用和精神健康服务管理局概述的康复领域。在与包括消费者和临床科学家在内的康复专家小组以及一小群消费者协商后，该工具被缩小到67个项目，并对从两个州的门诊心理健康诊所招募的166名个人进行了管理。运用项目反应理论和经典的项目分析，选择最适合的项目，减少项目冗余，提高量表的心理测量性能。主成分分析和验证性因子分析进一步检验量表测量的回收率维度。结果：MARS对于患有严重精神疾病的个体来说是非常实用的。它具有良好的内部一致性（Cronbach’s alpha=.95）和重测信度（r=.898），具有良好的面孔效度和内容效度。结论：这些数据为使用MARS来衡量严重精神疾病患者的康复提供了初步支持。（精神科服务63:48-53,2012）
Objectives: The authors describe the development of the Maryland Assessment of Recovery in People with Serious Mental Illness, or MARS, a 25-item self-report instrument that measures recovery of people with serious mental illness, and report a study of its psychometric properties. Methods: Doctoral-level scientists with expertise in serious mental illness drafted a set of survey items about the recovery process. Items reflected recovery domains outlined by the Substance Abuse and Mental Health Services Administration. After consultation with a panel of experts on recovery that included consumers and clinical scientists and with a small group of consumers, the instrument was narrowed to 67 items and administered to 166 individuals recruited from outpatient mental health clinics in two states. Item response theory and classical item analysis were used to select best-fitting items, reduce item redundancy, and improve the psychometric properties of the scale. Principal components analysis and confirmatory factor analysis were conducted to further examine dimensions of recovery measured by the scale. Results: The MARS is quite practical for use with individuals with serious mental illness. It demonstrated excellent internal consistency (Cronbach's alpha=.95) and test-retest reliability (r=.898) and good face and content validity. Conclusions: The data provide initial support for use of the MARS to measure recovery of people with serious mental illness. (Psychiatric Services 63:48-53, 2012)
