流调中心抑郁量表全国城市常模的建立

目的:验证流调中心抑郁量表(The Center for Epidemiological Studies Depression Scale,CES-D)在我国城市人群中不同年龄组的适用性,并建立各年龄组常模。方法:采用横断面研究方法,在全国21省39座城市收集普通人群样本16047名年龄11～100岁,平均(37.7±21.3)岁]以建立常模,在4个城市的精神科门诊与住院病人中选取病人样本349名年龄16～81岁,平均(32.0±12.1)岁]以检验效标效度。从普通人群样本中抽取北京、东莞、包头的199名企业职工、100名大学生、30名教师进行了间隔8周的重测,以检验重测信度。结果:CES-D的Cronbachα系数为0.90,各因素的Cronbachα系数为0.68～0.86;间隔8周的重测信度为0.49(P0.01),各因素重测相关为0.39～0.51(P0.01);验证性因素分析支持原量表4因素的结构(RMSEA=0.057,CFI=0.976,GFI=0.948);心理疾病患者CES-D得分高于普通人群(21.72±13.39)vs.(13.24±10.33),P0.01)],其中抑郁患者得分最高(27.82±14.42),P0.01];不同年龄组CES-D得分差异有统计学意义,60岁以上组得分高于60岁以下各组(P0.01)。结论:中文版流调中心抑郁量表适用于我国不同年龄群体,是一个可靠而有效的自评式抑郁症状测量工具。

Development of the Chinese age norms of CES-D in urban area

Objective: To test applicability of the Center for Epidemiological Studies Depression Scale (CES-D) in different age groups in urban China, and to develop age norms. Methods: In this cross-sectional study, the CES-D was administrated to 16047 community participants with average age of (37.7±21.3) years (age ranged 11～100) in 21 provinces, who were as the norming sample. Criterion validity was tested in 349 psychiatric patients with average age of (32.0±12.1) years (age ranged 16～81) in 4 cities. A subsample (199 workers, 100 col-lege students, and 30 teachers in Beijing, Dongguan, and Baotou) was drawn from the national sample to provide 8 week interval test-retest reliability. Results: The Cronbach α was 0.90 for the scale, and 0.68～0.86 for its fac-tors. The 8 week interval test-retest correlation was 0.49 for the scale (P <0.01) and 0.39～0.51 for factors (P<0.01) . The result of confirmatory factor analysis supported the original 4-factor structure (RMSEA=0.057, CFI =0.976, GFI=0.948) . Patients scored higher than community sample (21.72±13.39 ) vs.(13.24±10.33),P <0.01], and depression patients scored the highest (27.82±14.42), P<0.01] . Age difference was signifi-cant. Age groups over 60-year-old scored higher than all the other age groups under 60-year-old (P<0.01). Con-clusion: The Chinese version of CES-D shows good refiability and validity across all ages in urban population-
