【摘要】：目的探讨老年抑郁量表(GDS-5)在城乡项目功能差异(DIF)中的应用。方法 2012年1—2月利用GDS-5对老龄化期望研究中的550例老年人进行资料收集。采用χ2检验分析GDS-5各条目〔条目1"您对您现在的生活是否基本上满意"、条目2"您是否经常感到无聊、厌倦"、条目3"您是否常感到生活没有希望"、条目4"您是否常更想待在家里而不喜欢外出"、条目5"您是否觉得像现在这样活着毫无意义"〕的城乡差异;采用单维性检验分析主要指标〔比较拟合指数(CFI)、非规范拟合指数(TLI)、近似误差均方差(REMSEA)、标准化残差均方根(SRMR)〕;采用EASY-DIF软件包进行GDS-5城乡DIF的探测。结果条目2、条目3的城乡差异比较,差异有统计学意义(P0.05);其余条目的城乡差异比较,差异无统计学意义(P0.05)。单维性检验显示,CFI、TLI、REMSEA、SRMR均符合适配标准,表明GDS-5各条目测量的是同一概念特质,具有较好的结构效度。EASY-DIF软件包分析结果显示,条目2、条目3的MH值比较,差异有统计学意义(P0.05);其他条目的 MH值比较,差异无统计学意义(P0.05)。条目2、条目3的ΔαMH值分别为0.915、1.279。结论 GDS-5的条目3存在中等强度城乡DIF问题,今后在解释抑郁城乡差异时需注意条目城乡DIF问题。
[Abstract]:Objective to explore the application of elderly depression scale (GDS-5) in urban and rural item function difference (DIF). Methods GDS-5 was used to collect data from 550 elderly people in the study of Aging expectation in January and February 2012. 蠂 2 test was used to analyze the items of GDS-5 (item 1, "are you basically satisfied with your present life", item 2, "do you often feel bored and tired", item 3, "do you often feel that your life is hopeless", Item 4, "do you often prefer to stay at home rather than go out", item 5, "do you feel that there is no point in living like this") the difference between urban and rural areas; The main indexes (comparison fitting index (CFI), nonstandard fitting exponent (TLI), approximation error mean square error (REMSEA), standardized residual mean square root (SRMR);) were analyzed by one-dimensional test. The EASY-DIF software package was used to detect the DIF in urban and rural areas of GDS-5. Results the differences between urban and rural areas of item 2 and item 3 were statistically significant (P0.05), while the differences of other items were not statistically significant (P0.05). One-dimensional test showed that CFI,TLI,REMSEA,SRMR met the adaptation criteria, indicating that each item of GDS-5 measured the same conceptual trait and had good structural validity. The results of EASY-DIF software package analysis showed that item 2, The MH value of item 3 was significantly different (P0.05). There was no significant difference in MH value of other items (P0.05). For entry 2, the 螖伪 MH values for entry 3 are 0.915 / 1.279, respectively. Conclusion item 3 of GDS-5 has the problem of moderate intensity DIF in urban and rural areas. Attention should be paid to the problem of urban-rural DIF in explaining the difference between urban and rural depression in the future.
