Self-management is an important factor in maintaining and promoting mental health and recovery from mental health challenges. Thus, it is important to assess and support mental health self-management. In this study, we aimed to develop the Japanese version of the Mental Health Self-management Questionnaire (MHSQ-J), a scale to assess mental health self-management strategy, and clarify its psychometric properties among people with mental illness living in Japan. An anonymous self-administered survey including MHSQ-J was conducted for psychiatric outpatient users (N = 295), and 104 of the participants completed MHSQ-J again about two weeks later. Internal consistency was assessed with Cronbach’s α, and test-retest reliability was confirmed by the intraclass correlation coefficient (ICC). Construct validity was assessed based on structural validity with confirmatory factor analysis (CFA) and exploratory factor analysis (EFA), and hypotheses testing. The Self-management Skill Scale, the University of Tokyo Health Sociology version of the Sense of Coherence Scale ver1.2, the Japanese version of Self-identified Stage of Recovery Part-B, the Japanese version of the Flourishing Scale, and the Japanese version of the WHO Disability Assessment Scale 2.0 were used for hypotheses testing. Data from 243 respondents were analyzed. The result of CFA, the goodness-of-fit indices showed marginal fit (AGFI = .830, CFI = .852, RMSEA = .072). EFA identified three factors (Clinical, Empowerment, and Vitality), and the results suggested that the factor structure of the Japanese version of MHSQ was similar to the original 3-factor structure. Significant correlations were found with the hypotheses testing variables related to self-management and recovery, especially on the total score, the Empowerment subscale, and the Vitality subscale. Cronbach’s α (Clinical: .65, Empowerment: .81, Vitality: .75, Total: .83) and ICC (Clinical: .75, 95% confidence interval (CI) [.62, .84], Empowerment: .81, 95% CI [.70, .88], Vitality: .62, 95% CI [.44, .75], Total: .84, 95% CI [.75, .90]) indicated good reliability. The results show that MHSQ-J has acceptable reliability and validity to measure the use of self-management strategies for mental health among community living people with mental illness in Japan.

日文版《心理健康自我管理调查表》在居住在社区中的精神疾病患者中的信度和效度

自我管理是维持和促进心理健康以及从心理健康挑战中恢复的重要因素。因此，评估和支持心理健康自我管理非常重要。在这项研究中，我们旨在开发日文版的《心理健康自我管理调查表》（MHSQ-J），该量表用于评估心理健康自我管理策略，并阐明居住在日本的精神疾病患者的心理测量特性。一项针对精神科门诊患者的匿名自我管理调查（包括MHSQ-J）（N = 295），约有两周后，有104名参与者再次完成了MHSQ-J。内部一致性用Cronbach'sα评估，再测试信度通过类内相关系数（ICC）确认。基于结构效度，验证性因子分析（CFA）和探索性因子分析（EFA）以及假设检验，对构建体有效性进行了评估。自我管理技能量表，东京大学健康社会学版本的连贯感量表ver1.2，日语版的自我确定恢复阶段B部分，日语版的蓬勃发展量表和日语版世卫组织残疾评估量表2.0中的样本用于假设检验。分析了来自243位受访者的数据。CFA的结果（拟合优度指数）显示为边际拟合（AGFI = .830，CFI = .852，RMSEA = .072）。全民教育确定了三个因素（临床，授权和活力），结果表明日文版MHSQ的因素结构与原始的三因素结构相似。与自我管理和恢复相关的假设检验变量之间存在显着相关性，特别是在总分，赋权子量表和活力子量表上。克伦巴赫（Cronbach'sα）（临床：.65，授权：.81，活力：.75，总计：.83）和ICC（临床：.75，95％置信区间（CI）[.62，.84]，授权：.81 ，95％CI [.70，.88]，生命力：.62、95％CI [.44，.75]，总计：.84、95％CI [.75，.90]）表明具有良好的可靠性。结果表明，MHSQ-J具有可接受的信度和效度，可以衡量日本社区生活在精神疾病患者中自我管理策略对心理健康的使用情况。克伦巴赫（Cronbach'sα）（临床：.65，授权：.81，活力：.75，总计：.83）和ICC（临床：.75，95％置信区间（CI）[.62，.84]，授权：.81 ，95％CI [.70，.88]，生命力：.62、95％CI [.44，.75]，总计：.84、95％CI [.75，.90]）表明具有良好的可靠性。结果表明，MHSQ-J具有可接受的信度和效度，可以衡量日本社区生活在精神疾病患者中自我管理策略对心理健康的使用情况。克伦巴赫（Cronbach'sα）（临床：.65，授权：.81，活力：.75，总计：.83）和ICC（临床：.75，95％置信区间（CI）[.62，.84]，授权：.81 ，95％CI [.70，.88]，生命力：.62、95％CI [.44，.75]，总计：.84、95％CI [.75，.90]）表示良好的可靠性。结果表明，MHSQ-J具有可接受的信度和效度，可以衡量日本社区生活在精神疾病患者中自我管理策略对心理健康的使用情况。
