社区老年人抑郁筛查量表的初步编制及信度效度检验

目的编制社区老年人抑郁筛查量表。方法经文献复习、小组讨论和专家咨询确定了60个条目组成的条目池,在93名社区老年人和59名老年抑郁症患者中测试,并进行项目分析形成正式量表。然后在200名社区老年人和68名老年抑郁症患者中检验量表的信度和效度。结果量表最终纳入30个条目,所有条目在病例组的发生率明显高于社区组,内部一致性Cronbach’sα系数为0.98,一周后重测信度为0.68(P<0.05),与抑郁自评量表(SDS)标准分的相关系数为0.71(P<0.05),探索性因素分析揭示了量表单维的因素结构。在量表分数取临界值14时,灵敏度为91.20%,特异度为93.00%。结论本次研究编制的社区老年人抑郁筛查量表具有较好的信度和效度。

Construction, reliability and validity test of depression screening scale for community elder

Objective To develop a depression screening scale for community elder. Methods An item pool consisted of 60 items was constructed through review, panel discussion and expert consultation. Item analysis was performed in a sample of 93 community-dwelling older people and 59 geriatric depression patients. Then the reliability and validity test of official screening scale was performed in 200 community elder people and 68 geriatric depression patients. Results The screening scale was consisted of 30 items and the incidence rate of each item in patients was higher than the community elder. The Cronbach＇sαcoefficient was 0.98, and test-retest reliability after one week interval was 0.68（P〈0.05）. The to-tal score of this screening scale was positively correlated with SDS standard scores （r=0.71, P〈0.05）. Exploratory factor analysis indicated that the scale was unidimensional. When the total score of scale was 14, the sensitivity was 91.20%and the specificity was 93.00%. Conclusion The depression screening scale for community-dwelling elder shows good relia-bility and validity.
