Many older adults with moderate or severe dementia also have depression, but identifying depressive symptoms in these individuals can be challenging. The Depressive Symptom Assessment for Older Adults (DSA), a newly developed instrument designed to evaluate older adults for depression, regardless of their cognitive status, facilitates longitudinal evaluation. This investigation examined the psychometric properties of the DSA in older adults (n = 68) with moderate or severe dementia. Internal consistency for the overall instrument and three of the six subscales, inter-rater reliability, and concurrent validity were established. Preliminary factor analysis yielded two strong factors; however, the other four factors were conceptually unclear. Although the DSA performed well statistically, the instrument may have over-identified depressive symptoms related to disagreeable behavior and lethargy and may have under-identified other depressive symptoms.
许多患有中度或重度痴呆症的老年人也患有抑郁症，但识别这些人的抑郁症状可能具有挑战性。老年人抑郁症状评估量表（DSA）是一种新开发的工具，旨在评估老年人是否患有抑郁症，无论其认知状态如何，有助于进行纵向评估。本研究调查了DSA在患有中度或重度痴呆症的老年人（n = 68）中的心理测量特性。确定了整个量表以及六个子量表中的三个子量表的内部一致性、评分者间信度和同时效度。初步因子分析产生了两个强因子；然而，其他四个因子在概念上不明确。尽管DSA在统计学上表现良好，但该工具可能过度识别了与不良行为和嗜睡相关的抑郁症状，而可能未充分识别其他抑郁症状。
