流调中心抑郁水平评定量表在农村人群测量的信效度评价

目的 研究流调中心抑郁水平评定量表(CES-D)在农村人群测量的信效度.方法 以Hamilton抑郁量表(HAM-D)为标准,评价CES-D的区分效度和效标效度.在大连市庄河和金州两地区选取了330名农村居民.主要采用相关分析和探索性因子分析评价量表的信度和效度.结果 量表的Cronbach α系数为0.74,条目与总分之间的平均相关系数为0.59.探索性因子分析提取了情感和躯体症状,人际关系冲突2个因子(累计解释的方差为51.98%).各条目的 负荷范围在0.42～0.83.CES-D平均得分抑郁组[(22.80±10.28)分]和非抑郁组[(15.36±5.76)分]之间差异有显著性( t =2.60,P =0.01).CES-D与HAM-D的相关系数为0.50 ( P <0.01).结论 CES-D在农村人群中测量具有较为理想的信效度.

Reliability and validity of the center for epidemiologic studies depression scale in rural populations

Objective To assess the reliability and validity of the center for epidemiological studies depression scale (CES-D) in rural populations. Methods CES-D was administered to 330 rural residents in Jinzhou and Zhuanghe district of Dalian city. Hamilton Rating Scale for Depression (HAM-D) was used as standards to assess the discriminant validity and criterion validity. Statistical analysis included Pearson's correlations and the exploratory factor analysis. Results The Cronbach α was 0.74,and the average item-total correlation was 0.59. Two factors were extracted by using exploratory factor analysis:affective and somatic symptoms and interpersonal problems. The range of factor loading was between 0.42 and 0.83. CES-D mean scores were significantly different between the depressive group (22.80±10.28) and non-depressive group (15.36±5.76. t =2.60,P =0.01). The correlation coefficient between CES-D and HAM-D was 0.50( P <0.01). Conclusion The reliability and validity of CES-D for rural populations is acceptable.
