To establish the factor structure, reliability and validity of a brief CESD scale among Community dwelling older adults in Singapore.
Data were derived from interviews conducted among 1,013 randomly selected non-institutionalized older adults aged 65 years and above in Singapore. First, Confirmatory Factor Analysis (CFA) was conducted to test three factors in the entire sample: a one-factor model, a two-factor model (Depressed affect, Positive affect) and a three-factor model (Depressed affect, Somatic retardation, and Positive affect). Next, Multi-Group Analysis was conducted to test the scale invariance for male and female older adults.
Findings supported a two-factor model--depressed affect and positive affect for the entire sample. In addition, multi-group analysis showed the two-factor structure to be invariant for male and female older adults.
Brief CESD demonstrates adequate reliability and validity. The CESD scores can be used to compare symptoms of depression between male and female older adults.
在新加坡社区居住的老年人中建立简短的流调中心抑郁量表（CESD）的因子结构、信度和效度。
数据来源于对新加坡1013名随机抽取的65岁及以上非机构化老年人进行的访谈。首先，进行验证性因子分析（CFA）以检验整个样本中的三个因子：单因子模型、双因子模型（抑郁情绪、积极情绪）和三因子模型（抑郁情绪、躯体迟缓、积极情绪）。接下来，进行多组分析以检验该量表在老年男性和女性中的不变性。
研究结果支持整个样本的双因子模型——抑郁情绪和积极情绪。此外，多组分析表明双因子结构在老年男性和女性中具有不变性。
简短的CESD具有足够的信度和效度。CESD得分可用于比较老年男性和女性之间的抑郁症状。
