The Geriatric Depression Scale (GDS) is one of the most widely used self-rated mood questionnaires for older adults. It is highly correlated with clinical diagnoses of depression and has demonstrated validity across different patient populations. However, the reliability of the GDS among African American older adults remains to be firmly established. In a baseline sample of 401 African American adults age 51 and over, the GDS-15 item short form demonstrates good internal consistency (KR20=.71). Stability over a 15-month interval in a retest sample of 51 adults is deemed adequate (r=.68). These findings support the use of the GDS-15 item short form as a reliable mood questionnaire among African American older adults.
老年抑郁量表（GDS）是针对老年人使用最广泛的自评情绪问卷之一。它与抑郁症的临床诊断高度相关，并且在不同患者群体中都已证明其有效性。然而，GDS在非裔美国老年人中的可靠性仍有待确定。在401名年龄在51岁及以上的非裔美国成年人的基线样本中，GDS - 15项简表显示出良好的内部一致性（KR20 = 0.71）。在51名成年人的重测样本中，15个月间隔期内的稳定性被认为是足够的（r = 0.68）。这些发现支持将GDS - 15项简表用作非裔美国老年人中可靠的情绪问卷。
