The purpose of the present study was to examine the internal consistency reliability and construct validity of the Caregiving Burden Instrument in Korean informal caregivers of stroke survivors.
A descriptive survey design was used with a convenience sample of 208 primary caregivers of stroke survivors. Internal consistency reliability was assessed using Cronbach's alpha coefficients. Construct validity was assessed using exploratory and known-group analysis.
Each subscale and the total scale demonstrated satisfactory internal consistency reliability. Exploratory factor analysis identified five factors: family support, patient's dependency, physical health, financial burden, and psychological health, which together accounted for 62.7% of the variance. Known-group analysis indicated that caregivers with more than one year of experience reported significantly higher mean scores for the total burden score and its five subscales compared to those with less than one year.
This 23-item instrument demonstrates good internal consistency reliability and construct validity. The tool can be used to effectively assess burden in caregivers of stroke survivors and the data obtained can form the basis for the development of family interventions.
本研究旨在检验脑卒中幸存者的韩国非正式照顾者使用照顾负担量表的内部一致性信度和结构效度。
采用便利抽样法，对 208 名脑卒中幸存者的主要照顾者进行描述性调查设计。采用克朗巴赫 α 系数评估内部一致性信度。采用探索性和已知组分析评估结构效度。
各分量表和总量表均表现出满意的内部一致性信度。探索性因子分析确定了五个因素：家庭支持、患者依赖、身体健康、经济负担和心理健康，它们共同解释了 62.7%的方差。已知组分析表明，与少于一年的照顾者相比，有一年以上经验的照顾者的总负担评分及其五个分量表的平均得分显著更高。
这个包含 23 个项目的工具具有良好的内部一致性信度和结构效度。该工具可用于有效评估脑卒中幸存者照顾者的负担，所得数据可作为家庭干预措施制定的基础。
