The relationships between depression, measured by the Zung Self-Rating Depression Scale (SDS), somatic symptoms based on self-reports, and health based on medical evaluations, were investigated in 60 depressed older persons (median age 64.5 years) in relatively good physical health. No relationship was found between health ratings and depression scores, but a significant association emerged between a Somatic Symptom subscale, specifically the single item of fatiguability, physicians' ratings of health, and depression scores. Results of factor analyses of the Zung Self-Rating Depression Scale were similar to those reported in previous studies and indicated a factor structure apparently based on the positioning of the positively and negatively worded items. It is suggested, therefore, that further investigations be carried out to evaluate the possible response bias on this scale.
在60名身体健康状况相对良好的老年抑郁症患者（中位年龄64.5岁）中，研究了用zung自评抑郁量表（SDS）测量的抑郁症、基于自我报告的躯体症状以及基于医学评估的健康状况之间的关系。未发现健康评分与抑郁评分之间存在关联，但躯体症状子量表，特别是疲劳单项、医生对健康的评分与抑郁评分之间出现了显著关联。zung自评抑郁量表的因子分析结果与先前研究报告的结果相似，表明因子结构显然基于正负措辞项目的定位。因此，建议进一步开展调查，以评估该量表可能存在的反应偏差。
