目的：检查 15 项老年抑郁量表 (GDS-15) 的心理测量特性，这是一项简短的抑郁症筛查措施。设计：横断面。设置：纽约州西部、西弗吉尼亚州和俄亥俄州的 19 个县。参与者：960 名 65 岁及以上功能受损、认知完好、社区居住的初级保健患者。测量：GDS-15，测量的重度抑郁症使用小型国际神经精神访谈、抑郁情绪、生活满意度、自杀意念和报告的自杀企图。结果：探索性因素分析表明，此类患者的 GDS-15 采用双因素结构，其中分量表评估抑郁和积极情感。 Cronbach α 系数提供了适度但可接受的内部一致性可靠性的证据。 GDS-15 与抑郁情绪、生活满意度和自杀意念测量之间的显着关联证明了结构有效性，而区分抑郁和非抑郁患者的可接受的敏感性和特异性证明了标准有效性。低功能损伤和高功能损伤患者之间的内部一致性信度和结构效度没有显着差异。该量表的一个显着弱点是它与自杀未遂状态的相关性较低。结论：总的来说，这项研究提供了证据，表明当对功能受损、认知完整的社区初级保健患者样本进行 GDS-15 测试时，其具有令人印象深刻的心理测量特性。
OBJECTIVES: To examine the psychometric properties of the 15-item Geriatric Depression Scale (GDS-15), a brief depression screening measure.DESIGN: Cross-sectional.SETTING: Nineteen counties in western New York, West Virginia, and Ohio.PARTICIPANTS: Nine hundred sixty functionally impaired, cognitively intact, community-dwelling primary care patients aged 65 and older.MEASUREMENTS: The GDS-15, major depression as measured using the Mini-International Neuropsychiatric Interview, depressed mood, life satisfaction, suicidal ideation, and reported suicide attempts.RESULTS: Exploratory factor analyses suggested a two-factor structure for the GDS-15 in this category of patients, with component subscales assessing depression and positive affect. Cronbach alpha coefficients provide evidence for moderate, although acceptable, internal consistency reliability. Significant associations between the GDS-15 and measures of depressed mood, life satisfaction, and suicidal ideation demonstrated construct validity, whereas acceptable sensitivity and specificity to discriminate between depressed and nondepressed patients demonstrated criterion validity. Internal consistency reliability and construct validity did not differ significantly between patients with low and high functional impairment. A significant weakness of the scale is its low correlation with suicide attempt status.CONCLUSION: In general, this study provides evidence of impressive psychometric properties of the GDS-15 when administered to a sample of functionally impaired, cognitively intact, community-dwelling primary care patients.
