Individuals with intellectual disabilities are as vulnerable to depression as their typically developing peers. This study aimed to verify the reliability and validity of the Center for Epidemiologic Studies Depression Scale (CES-D) in individuals with intellectual disabilities and determine whether the scale is appropriate for screening them.
Data obtained from 275 participants from Korea's Disabled People's Development Institute were analysed. The measure used 11 items from the CES-D. Confirmatory factor analysis and Cronbach's α of internal consistency reliability were employed for examining validity and reliability.
Cronbach's α of total scale was 0.860. Cronbach's α of the subscales was 0.842 in depressive affect, 0.647 in positive affect, 0.783 in somatic/vegetative symptoms and 0.837 in interpersonal problems. Bifactor and four-factor structures were verified using confirmatory factor analysis.
The validity and reliability of the CES-D-11 for individuals with intellectual disabilities were verified. Results indicated the cut-off and subscale scores.
智力残疾个体与发育正常的同龄人一样容易患抑郁症。本研究旨在验证流行病学研究中心抑郁量表（CES-D）在智力残疾个体中的信度和效度，并确定该量表是否适合对他们进行筛查。
对从韩国残疾人发展研究所获取的275名参与者的数据进行分析。该测量采用了CES-D中的11个项目。采用验证性因素分析和内部一致性信度的克朗巴哈α系数来检验效度和信度。
总量表的克朗巴哈α系数为0.860。分量表的克朗巴哈α系数在抑郁情绪方面为0.842，在积极情绪方面为0.647，在躯体/植物神经症状方面为0.783，在人际关系问题方面为0.837。使用验证性因素分析验证了双因素和四因素结构。
验证了CES-D-11在智力残疾个体中的效度和信度。结果表明了临界值和分量表分数。
