Abstract

Purpose: This study aims to examine the psychometric properties of the Recovering Quality of Life- Japanese version (ReQoL-J) for use in the community setting.

Methods: This cross-sectional study was conducted among service users of community mental health service facilities. A series of confirmatory factor analyses (CFAs) was performed. After the best-fitting model was identified, omega indices, and intraclass correlation (ICC) were calculated to evaluate dimensionality and reliability. The correlation coefficients between the ReQoL-J scores and the other scales were calculated for testing construct validity. We also estimated the correlation coefficients between the ReQoL-J-10 and - 20.

Results: A total of 395 service users from 23 facilities in Japan participated in this study. Of these, 66 responded to the test-retest reliability. The bifactor model showed the best fit to the data: χ²/df = 1.74, CFI = 0.993, RMSEA = 0.031, and SRMR = 0.038. ECV and OmegaH indicated unidimensionality. ICC for the Re-QoL-J-10 and - 20 were 0.700 and 0.766, respectively. The ReQoL-J-10 showed a high correlation with the ReQoL-J-20 (r =.95, p <.001). The EQ-5D-5 L, a new brief scale for subjective personal agency (SPA-5), well-being and the quality of life scale (QLS) scores were positively correlated with the ReQoL-J score. On the other hand, the patient health questionnaire-9 (PHQ-9) and the WHODAS scores were negatively correlated with the ReQoL-J score.

Conclusion: Factor structure, internal consistency, test-retest reliability, and construct validity of the ReQoL-J were confirmed. The ReQoL-J is a promising tool as a patient-reported outcome measure in mental health services for the Japanese community setting.

目的：本研究旨在探讨日语版《生活质量康复》（ReQoL-J）在社区环境中使用的心理测量特性：这项横断面研究的对象是社区精神卫生服务机构的服务使用者。进行了一系列确证因子分析（CFAs）。在确定了最佳拟合模型后，计算了欧米茄指数和类内相关系数（ICC），以评估维度和可靠性。我们还计算了 ReQoL-J 评分与其他量表之间的相关系数，以检验结构效度。我们还估算了 ReQoL-J-10 和 - 20 之间的相关系数：共有来自日本 23 家机构的 395 名服务使用者参与了本研究。其中 66 人对测试-再测信度做出了回应。双因素模型与数据的拟合度最高：χ2/df = 1.74，CFI = 0.993，RMSEA = 0.031，SRMR = 0.038。ECV 和 OmegaH 显示了单维性。ReQoL-J-10 和 - 20 的 ICC 分别为 0.700 和 0.766。ReQoL-J-10 与 ReQoL-J-20 呈高度相关（r =.95，p 结论：ReQoL-J-20 与 ReQoL-J-20 呈高度相关（r =.95，p 结论）：ReQoL-J的因子结构、内部一致性、重测信度和构建效度均得到了证实。ReQoL-J 作为日本社区心理健康服务中的患者报告结果测量工具，前景广阔。
