In this study, we examined the characteristics of depression determination using four representative self-rating depression scales (Geriatric Depression Scale, GDS; Self-rating Depression Scale, SDS; Center for Epidermiologic Studies Depression Scale, CES-D; and Carroll Rating Scale, CRS) applied to Japanese community-dwelling elderly.
Subjects were 563 community-dwelling independent elderly living in twelve prefectures (330 males, 68,9±6.3 yr; 233 females, 68.1±5.8 yr).
Depression rates determined using SDS (45.8%) and CES-D (68.6%) were higher than those determined using GDS (5.7%) and CRS (14.7%). Although correlations of depression scale scores among the four scales were significant and comparable (r: 0.61 (GDS vs. SDS, p<0.01) to 0.78 (SDS vs. CES-D, p<0.01)), the agreement in depression determination varied among scales (kappa coefficients: 0.05 (GDS vs. CES-D, p>0.05) to 0.46 (SDS vs. CES-D, p<0.01)).
Similarities in depression determination were found between GDS and CRS, and between CES-D and SDS. Depression rates determined on the basis of cut-off point for each scale were higher for CES-D and SDS than for GDS and CRS. Depression determination using a four-point rating scale may overestimate a slightly depressive symptom, compared with that using a two-point scale.
本研究使用四种有代表性的自评抑郁量表（老年抑郁量表、抑郁自评量表、中心流行病学研究抑郁量表和卡罗尔评定量表）对日本社区居住的老年人进行抑郁判定，分析其特点。
研究对象为来自 12 个县的 563 名社区居住的独立老年人（男性 330 名，68.9±6.3 岁；女性 233 名，68.1±5.8 岁）。
使用 SDS（45.8%）和 CES-D（68.6%）判定的抑郁发生率高于 GDS（5.7%）和 CRS（14.7%）。尽管四种量表的抑郁评分之间存在显著相关性（r：0.61（GDS 与 SDS，p<0.01）至 0.78（SDS 与 CES-D，p<0.01）），但各量表在抑郁判定方面的一致性存在差异（kappa 系数：0.05（GDS 与 CES-D，p>0.05）至 0.46（SDS 与 CES-D，p<0.01））。
GDS 与 CRS、CES-D 与 SDS 之间存在相似的抑郁判定结果。基于各量表的切点进行抑郁判定，CES-D 和 SDS 的判定结果高于 GDS 和 CRS。与使用两点量表相比，使用四点量表进行抑郁判定可能会高估轻度抑郁症状。
