工作背景：康复被定义为一个复杂的过程，随着一个人超越精神疾病的灾难性影响，在生活中发展新的意义和目的。为了促进这一过程，人们强调了使用心理测量方法进行康复评估的必要性，然而，在日本还没有评估个体康复过程的方法。目的：开发日本版的康复评估量表（RAS），并检验其信度和效度。设计：本研究是一项横断面问卷调查。设置：参加者来自1间日间护理中心、1间精神病医院门诊诊所、5间用于社会康复的庇护工场、3个朋辈支援小组，以及2间精神病医院的6间住院病房。该调查包括237名患有慢性精神疾病的参与者，年龄在20岁或以上。为了进行分析，我们使用的数据从209名参与者没有缺失值的RAS，58.9%的男性和平均年龄为48.3 years.Methods：问卷包括日本版的24项RAS，作者开发的焦点小组认知访谈和解释回翻译程序。还包括Herth Hope指数、赋权量表、复原力量表、SF-8和BASIS-32。内部一致性的信度进行了评估Cronbach的α系数，和重测信度进行了评估的组内相关系数（ICC）和加权Kappa在一个随机选择的子样本（n = 24）。探索性和验证性因素分析以及与其他量表的相关性被用来检验RAS的因素效度、同时效度和结构效度。结果：总体RAS的Cronbach α系数为0.89。ICC和加权Kappa一般表示良好的重测信度。RAS项目的因素分析产生了五个因素：（a）目标/成功导向和希望，（B）对他人的依赖，（c）个人信心，（d）不受症状的支配，（e）愿意寻求帮助。“应对精神疾病不再是我生活的主要焦点”这一项目显示出负因素负荷。RAS总分与Herth Hope指数、Empowerment量表、Resilience量表、SF-8心理健康量表总分呈显著正相关;与BASIS-32精神症状和功能障碍呈显著负相关（p < 0.01）。本研究证实了日本版24-项目RAS目前生活在日本的社区和住院病房设置的慢性精神疾病患者。(C)2009爱思唯尔有限公司保留所有权利。
Background: Recovery is defined as a complex process of developing new meaning and purpose in life as one grows beyond the catastrophic effects of mental illness. To promote this process, the necessity of recovery assessment using psychometric measures has been emphasized; however, no measure to assess the individual recovery process is available in Japan.Objective: To develop a Japanese version of the Recovery Assessment Scale (RAS) and to examine its reliability and validity.Design: The study was a cross-sectional questionnaire survey.Settings: Participants came from 1 daycare, 1 outpatient clinic of a psychiatric hospital, 5 sheltered workshops used for social rehabilitation, 3 peer support groups, and 6 inpatient wards of 2 psychiatric hospitals.Participants: The Survey included 237 participants who had chronic mental illness and were aged 20 or older. For analysis, we used data from 209 participants who had no missing values on the RAS, with 58.9% male and a mean age of 48.3 years.Methods: The questionnaire consisted of the Japanese version of the 24-item RAS, developed by the authors with focus group cognitive interviews and the translation-back-translation procedure. Also included were the Herth Hope Index, Empowerment scale, Resilience scale, SF-8, and BASIS-32. Internal consistency reliability was assessed by Cronbach's alpha coefficients, and test-retest reliability was assessed by the intraclass correlation coefficient (ICC) and weighted kappa in a randomly selected subsample (n = 24). Exploratory and confirmatory factor analyses and correlations with other scales were used to examine the factor-based validity, concurrent and construct validity of the RAS. Results: Cronbach's alpha coefficient was 0.89 for the overall RAS. ICC and weighted kappa generally indicated good test-retest reliability. Factor analysis of the RAS items yielded five factors: (a) goal/success orientation and hope, (b) reliance on others, (c) personal confidence, (d) no domination by symptoms, and (e) willingness to ask for help. The item "Coping with mental illness is no longer the main focus of my life" showed an inverse factor loading. The overall RAS score significantly and positively correlated with the Herth Hope Index, Empowerment scale, Resilience scale, and SF-8 mental component summary; there was a significant negative correlation with BASIS-32 psychiatric symptoms and functional impairment (p, < 0.01).Conclusion: This study confirmed the reliability and validity of the Japanese version of the 24-item RAS among people with chronic mental illness currently living in communities and inpatient ward settings in Japan.
