贝克抑郁量表第2版中文版在凉山州彝族中学生中的信效度研究

Investigation of the Reliability and Validity of the Chinese Version of the Beck Depression Inventory-Ⅱ in Middle School Students of Yi Ethnicity in Liangshan Prefecture, China

摘要

摘要:
目的评估贝克抑郁量表第2版中文版（Chinese version of the Beck Depression Inventory, Second Edition, BDI-Ⅱ-C）在凉山州彝族中学生中的信度和效度。
方法采用分层整群抽样的方法选择466名凉山州彝族初一到高三共6个年级的学生完成BDI-Ⅱ-C的测试，对样本的人口学特征进行一般性描述，对样本数据进行独立样本t检验、卡方分析、信度分析，将样本随机分半分别进行探索性因子分析及验证性因子分析。
结果在凉山州彝族中学生样本中，BDI-Ⅱ-C的Cronbach's α系数为0.925。各个条目之间的相关系数在0.192～0.612之间，各个条目与总分之间的相关系数在0.492～0.761之间。探索性因子分析发现量表可分为三个维度，包括情绪症状、躯体症状和消极症状。验证性因子分析结果提示该三因子模型的各指标为χ²/df=1.604，比较拟合指数（comparative fit index, CFI）=0.940，Tucker-Lewis指数（Tucker-Lewis index, TLI）=0.932，增值拟合指数（incremental fit index, IFI）=0.941，估计误差均方根（root mean square error of approximation, RMSEA）=0.051。
结论 BDI-Ⅱ-C在凉山州彝族中学生中具有良好的信效度，但是结构效度中的聚合效度较差。

Abstract:
Objective To assess the reliability and validity of the Chinese version of the Beck Depression Inventory, Second Edition (BDI-Ⅱ-C) among Yi middle school students in Liangshan Prefecture.
Methods A stratified cluster sampling method was used to select 466 Yi middle and high school students in Liangshan Prefecture to respond to the BDI-Ⅱ-C. The general demographic characteristics of the samples were described, and independent sample t-test, chi-square test, and reliability analysis were conducted to analyze the data. The sample was randomly divided into 2 halves for exploratory factor analysis and confirmatory factor analysis.
Results The Cronbach's alpha coefficient for BDI-Ⅱ-C was 0.925 for the sample of Yi middle school students in Liangshan Prefecture. The correlation coefficients between individual items ranged from 0.192 to 0.612, and those between individual items and total scores ranged from 0.492 to 0.761. Exploratory factor analysis found that the scale could be divided into three dimensions, including emotional symptoms, somatic symptoms, and negative symptoms. Confirmatory factor analysis results revealed that the various indicators of the three-factor model were χ²/df=1.604, comparative fit index (CFI)=0.940, Tucker-Lewis index (TLI)=0.932, incremental fit index (IFI)=0.941, and root mean square error of approximation (RMSEA)=0.051.
Conclusion BDI-Ⅱ-C exhibits good reliability and validity among Yi middle school students in Liangshan Prefecture, but the convergent validity of the structural validity is poor.
