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.

日文版糖尿病照护者活动和支持量表的编制以及其信度和效度的验证

目的

这项研究的目的是调整和心理评估日本版的《糖尿病照料者活动和支持量表》（D-CASS-J），以使其与居住在日本的糖尿病患者在文化上相关。

方法

D-CASS原始版本的日文翻译已准备，更正和回译。包括访问伊势红十字会医院门诊糖尿病门诊的65岁以上糖尿病患者的家庭护理人员。计算Cronbach的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构建体的有效性。使用抑郁作为因变量，使用D-CASS-J和其他变量作为解释变量，进行了层次多元回归分析。计算D-CASS-J得分与支持负担量表得分之间的Pearson相关系数，以验证与标准相关的有效性。

结果

该分析包括268个主题。Cronbach的α系数为0.86。因子分析显示出与D-CASS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构造的有效性。D-CASS-J得分与支持负担量表得分显着相关。

结论

对于日本的老年糖尿病患者的家庭护理人员，D-CASS-J可以用作评估在为患者提供支持时遇到的困难的工具。
