一百九十八名在全科医生 (GP) 就诊的老年受试者被要求填写 15 项老年抑郁量表 (GDS15)。从 194 个（98%）中获得了可分析的结果。其中，67 人 (34%) 的得分高于 GDS15 临界值 (4/5)，具有显着的抑郁症状。 87.6%的人认为问卷可以接受，只有3.6%的人认为非常困难或压力很大。 GDS15 具有高水平的内部一致性（Cronbach's alpha = 0.80）。 GDS15 的所有单独项目均与总分和“案例性”显着相关（P < 0.01）：一个问题“您是否觉得您的生活很空虚？”识别出 84% 的“案例”。为了设计一个简短的量表来筛查老年初级保健患者的抑郁症，我们对数据进行了逻辑回归分析。生成了十个 (GDS10)、四个 (GDS4) 和一个 (GDS1) 项目版本。这些短尺度与原始样本中的 GDS15 之间的一致性分别为 95%、91% 和 79%。 GDS10 的 Cronbach's alpha 值为 0.72，GDS4 的 Cronbach's alpha 值为 0.55。然后，在 120 名患者的独立样本中验证了短量表，这些患者可以获得 GDS 数据和详细的精神病学访谈（老年精神状态表，GMS）的结果。 GDS10 针对 GMS 病例的敏感性和特异性分别为 87% 和 77%（截止值 3/4）； GDS4 的分别为 89% 和 65%（截止值 0/1）以及 61% 和 81%（截止值 1/2）。 GDS1 的敏感性和特异性分别为 59% 和 75%。结论是，这些简短的量表可能有助于帮助全科医生和执业人员识别患有明显抑郁症状的老年患者。
One-hundred and ninety-eight elderly subjects attending their general practitioners (GPs) were asked to complete the 15 item Geriatric Depression Scale (GDS15). Analysable results were obtained from 194 (98%). Of these, 67 (34%) scored above the GDS15 cut-off (4/5) for significant depressive symptomatology. 87.6% found the questionnaire to be acceptable and only 3.6% found it very difficult or very stressful. The GDS15 had a high level of internal consistency (Cronbach's alpha = 0.80). All the individual items of the GDS15 associated significantly (P < 0.01) with total score and 'caseness: A single question ''do you feel that your life is empty?'' identified 84% of 'cases'. In an attempt to devise short scales to screen elderly primary care patients for depression, the data were subjected to logistic regression analysis. Ten (GDS10), four (GDS4) and one (GDS1) item versions were generated. Agreement between these short scales and the GDS15 in the original sample was 95, 91 and 79% respectively. Cronbach's alpha was 0.72 for the GDS10 and 0.55 for the GDS4. The short scales were then validated in an independent sample of 120 patients in whom both GDS data and the results of a detailed psychiatric interview (the Geriatric Mental Status Schedule, GMS) were available. The sensitivity and specificity of the GDS10 against GMS caseness were 87 and 77% (cut-off 3/4); those of the GDS4 were 89 and 65% (cut-off 0/1) and 61 and 81% (cut-off 1/2). Sensitivity and specificity for the GDS1 were 59 and 75%. It is concluded that these short scales may be useful in helping GPs and practice staff to identify elderly patients with significant depressive symptoms.
