| 背景 严重精神障碍患者的监护人对患者康复和回归社会有重要促进作用，但目前尚缺乏对其监护能力进行量化评定的工具，亟需开发科学的测量工具。目的 编制适用于严重精神障碍患者监护人监护能力的评定量表并进行信效度检验，为构建科学、合理的监护人监护能力评定工具提供参考。方法 通过文献回顾法和访谈构建量表条目池，邀请15名专家进行两轮函询。选取364名广州市严重精神障碍患者监护人进行调查。使用项目分析以及探索性因子分析对量表条目进行筛选和优化，并进一步通过验证性因子分析验证量表的结构效度。以量表各条目的内容效度指数（I-CVI）及总量表的平均内容效度指数（S-CVI/Ave）评估量表内容效度。通过Cronbach’s α系数和分半信度检验量表的信度。结果 本研究编制的严重精神障碍患者监护人监护能力量表共25个条目，包括监护意愿、监护知识和行为、监护自我效能三个维度。项目分析结果显示：所有条目均达到相应标准，予以保留。效度检验：I-CVI为0.800~1.000，S-CVI/Ave为0.964。各条目在相应因子上的因子载荷为0.596~0.976，模型拟合良好：卡方自由度比（χ2/df）=2.444，Tucker-Lewis系数（TLI）=0.908，拟合指数（CFI）=0.917，标准化均方根残差（SRMR）=0.049，近似误差均方根（RMSEA）=0.089。信度检验：总量表Cronbach’s α系数为0.966，分半信度系数为0.915。结论 本研究编制的严重精神障碍患者监护人监护能力量表具有良好的信度和效度，对严重精神障碍患者监护人监护能力的评定具有一定的应用价值。 |

| Background Guardians of patients with severe mental disorders play an important role in supporting the patients’ recovery and reintegration into society. It is necessary to develop a scientific tool since there is a lack of tools to quantitatively assess the guardianship ability. Objective We aimed to explore and develop an assessment scale for the guardianship ability of guardians of patients with severe mental disorders, and to evaluate the scale’s reliability and validity, thereby providing a scientific sound and reasonable tool for assessing guardianship abilities. Methods A pool of scale items was constructed through a literature review and interviews, followed by two rounds of expert consultation with 15 specialists. 364 guardians of patients with severe mental disorders in Guangzhou were investigated. The scale items were screened and optimized using item analysis and exploratory factor analysis, and the structural validity of the scale was further verified through confirmatory factor analysis. The content validity of the scale was evaluated by the item-level content validity index (I-CVI) and the average scale-level content validity index (S-CVI/Ave). The reliability of the scale was tested by Cronbach’s α coefficient and split-half reliability. Results In this study, the guardianship ability scale for guardians of patients with severe mental disorders consists of 25 items, divided into three dimensions: guardianship willingness, guardianship knowledge and behavior, and guardianship self-efficacy. The results of the item analysis showed that all items met the corresponding criteria and were retained. Validity test: The I-CVI ranged from 0.800 to 1.000, and the S-CVI/Ave is 0.964. Factor loadings of each item on the corresponding factors ranged from 0.596 to 0.976; the model demonstrated good fit: chi-square degree of freedom ratio (χ2/df) = 2.444, Tucker-Lewis index (TLI) = 0.908, comparative goodness of fit index (CFI) = 0.917, standardized root mean square residual (SRMR) = 0.049, root mean square residual (RMSEA) = 0.089. Reliability test: The total scale had a Cronbach’s α coefficient of 0.966, and the split half reliability coefficient was 0.915. Conclusion The guardianship ability scale developed in this study for guardians of patients with severe mental disorders shows good reliability and validity, providing a valuable reference for future assessments of guardianship ability for guardians of patients with severe mental disorders. |
