过度概括化自传体记忆问卷的编制及信效度分析

Development and reliability, validity analysis of overgeneral autobiographical memory questionnaire

摘要目的:编制过度概括化自传体记忆问卷(overgeneral autobiographical memory questionnaire,OGMQ),并检验其信效度。方法:通过文献检索、专家论证形成问卷初始项目。选取大学生被试1 911人进行初测。有效数据1 840份随机分为两等份,920份用于探索性因素分析,920份用于验证性因素分析和信效度分析。选取抑郁症被试和配对正常被试各30人以检测效标效度。结果:过度概括化自传体记忆问卷包含19个项目,二维度(搜寻构建、精加工)四因子(时空构建、控制构建、情境精加工、情绪精加工)结构。探索性分析提取了4个因子19个条目,KMO(Kaiser-Meyer-Olkin)系数为0.905,Bartlett球形检验:近似 χ2=4 728.134, df=171, P<0.001)。验证性分析显示时空构建因子、控制构建因子在构建维度上的因子负荷分别为0.770、0.539;情境精加工因子、情绪精加工因子在精加工维度上的因子负荷分别为0.911、0.800。问卷具有良好的内部一致性信度(Cronbach α=0.870)、结构效度(χ 2/ df=3.550,RMSEA=0.053,GFI=0.944,CFI=0.970,NFI=0.958,IFI=0.970)和效标效度[ r(OGMQ,AMT)=0.870; r(OGMQ,BDI)=0.507],能够有效区分抑郁症和正常群体(AUC=0.795)。 结论:本研究编制的过度概括化自传体记忆问卷信度和效度良好,可用于抑郁相关的研究与实践。

abstractsObjective:To develop overgeneral autobiographical memory questionnaire(OGMQ) and test its reliability and validity.Methods:Through literature search, expert opinions and group discussion the initial items of the questionnaire were formed. A random cluster method was adopted to select 1 911 college students for the preliminary test.Totally 1 840 valid questionnaires were obtained, and 920 of which were assessed for exploratory factor analyses and 920 of which were assessed for confirmatory factor analyses and reliability and validity analysis. Thirty subjects with depression and 30 normal subjects were selected to test its criterion validity.Results:The questionnaire consisted of 19 items, two dimensions (construction, elaboration) and four factors (spatial-temporal factor, control factor, context factor, emotion factor). Exploratory analysis extracted 4 factors and 19 items, KMO (Kaiser-Meyer-Olkin) = 0.905, Bartlett test: χ 2=4 728.134, df=171, P<0.001.Confirmatory analysis showed that the factor loads of spatio-temporal factor and control factor in the construction dimension were 0.770 and 0.539 respectively, while the factor loads of context factor and emotional factor in the elaboration dimension were 0.911 and 0.800 respectively. The questionnaire had good internal consistency reliability (Cronbach α=0.870), structural validity (χ 2/ df=3.550, RMSEA=0.053, GFI=0.944, CFI=0.970, NFI=0.958, IFI=0.970) and criterion validity ( r(OGMQ, AMT)=0.870, r(OGMQ, BDI)=0.507), and it was able to effectively distinguish between depressed and normal groups (AUC=0.795). Conclusion:The OGMQ has satisfactory validity and reliability, and meets the needs of psychometrics, which can be used in depression-related research and practice.
