Abstract

Background

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.

Methods

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.

Results

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.

Conclusions

The validity and reliability of the CES-D-11 for individuals with intellectual disabilities were verified. Results indicated the cut-off and subscale scores.

智障人士流行病学中心量表的因素结构

智障人士和正常发育的同龄人一样容易患抑郁症。本研究旨在验证美国流行病学研究中心抑郁量表（CES-D）在智障人群中的信度和效度，并确定该量表是否适合用于智障人群的筛查。方法对来自韩国残疾人发展研究所的275名参与者的数据进行分析。该测量使用了CES-D中的11个项目。效度和信度采用验证性因子分析和内部一致性信度的Cronbach’s α。结果总量表的Cronbach’s α为0.860。抑郁情绪量表的Cronbach’s α为0.842，积极情绪量表为0.647，躯体/植物症状量表为0.783，人际关系量表为0.837。采用验证性因子分析对双因子和四因子结构进行验证。结论ce - d -11量表在智力障碍人群中的效度和信度得到了验证。结果显示分界点和分量表得分。
