Abstract: 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.
