Purpose The purpose of the study was to adapt and psychometrically evaluate a Japanese language version of the Diabetes Caregiver Activity and Support Scale (D-CASS-J) to be culturally relevant for people with diabetes living in Japan. Methods A Japanese translation of the original version of the D-CASS was prepared, corrected, and back-translated. Family caregivers of patients with diabetes mellitus ages ≥65 years who visited the outpatient diabetes clinic of Ise Red Cross Hospital were included. Cronbach’s α coefficients were calculated as an assessment of internal consistency. Exploratory factor analyses were performed to verify construct validity. Hierarchical multiple regression analyses were performed using depression as the dependent variable and D-CASS-J and other variables as explanatory variables. Pearson’s correlation coefficients between D-CASS-J scores and the support burden scale scores were calculated to verify criterion-related validity. Results This analysis included 268 subjects. Cronbach’s α coefficient was .86. Factor analyses showed the same single-factor structure as the original version of the D-CASS. Hierarchical multiple regression analyses based on the conceptual model demonstrated construct validity. D-CASS-J scores were significantly correlated with support burden scale scores. Conclusions For family caregivers of elderly patients with diabetes in Japan, D-CASS-J can be used as a tool to evaluate difficulties experienced while providing support to patients.

日文版糖尿病照顾者活动和支持量表的编制及其信效度验证

目的 本研究的目的是调整日语版本的糖尿病护理人员活动和支持量表 (D-CASS-J) 并对其进行心理测量评估，使其与生活在日本的糖尿病患者具有文化相关性。方法 准备、更正和回译 D-CASS 原始版本的日文译本。包括到伊势红十字医院糖尿病门诊就诊的 65 岁以上糖尿病患者的家庭照顾者。计算 Cronbach α 系数作为内部一致性的评估。进行探索性因素分析以验证结构有效性。使用抑郁症作为因变量，D-CASS-J 和其他变量作为解释变量进行分层多元回归分析。计算 D-CASS-J 分数与支持负担量表分数之间的 Pearson 相关系数，以验证标准相关的有效性。结果 该分析包括 268 名受试者。Cronbach 的 α 系数为 0.86。因子分析显示与 D-CASS 的原始版本相同的单因子结构。基于概念模型的分层多元回归分析证明了结构有效性。D-CASS-J 分数与支持负担量表分数显着相关。结论 对于日本老年糖尿病患者的家庭照顾者，D-CASS-J 可作为评估在为患者提供支持时遇到的困难的工具。Cronbach 的 α 系数为 0.86。因子分析显示与 D-CASS 的原始版本相同的单因子结构。基于概念模型的分层多元回归分析证明了结构有效性。D-CASS-J 分数与支持负担量表分数显着相关。结论 对于日本老年糖尿病患者的家庭照顾者，D-CASS-J 可作为评估在为患者提供支持时遇到的困难的工具。Cronbach 的 α 系数为 0.86。因子分析显示与 D-CASS 的原始版本相同的单因子结构。基于概念模型的分层多元回归分析证明了结构有效性。D-CASS-J 分数与支持负担量表分数显着相关。结论 对于日本老年糖尿病患者的家庭照顾者，D-CASS-J 可作为评估在为患者提供支持时遇到的困难的工具。
