歧义情境解释偏向问卷的编制及信效度研究

Development and validation of interpretation bias questionnaire with ambiguous scenarios

目的以相似性评分任务(similarity rating task,SRT)为模板编制适用于我国文化背景的抑郁症解释偏向问卷并检验其信效度。方法在获得授权后,将认知行为矫正前瞻训练项目(cognitive behavior modification errors prospective training items,CBM-I)中的歧义段落翻译后进行第一轮筛选,将选出段落与经文化适应性改编后的SRT剩余歧义段落及自编歧义段落共同组成第二轮筛选问卷,筛选出14个歧义段落作为题项。最终以SRT为模板编制成歧义情境解释偏向问卷,并对477人施测,再对该问卷进行项目分析及信效度分析。结果两轮筛选后编制成包含14个题项的问卷,对问卷进行探索性因素分析提取出5个因素,累积贡献率为52.67%,验证性因素分析显示五因素模型拟合良好;Cronbach’sα系数为0.613,分半信度系数r=0.617;效度检验中的内容效度以目标句与陪衬句做配对t检验显示差异显著(t=-12.90,P<0.01),效度标度以中文版流调中心抑郁量表(center for epidemiologic studies depression scale,CES-D)做效标发现本问卷效标效度良好,二者总分显著相关(r=-0.224,P<0.01)。结论歧义情境解释偏向问卷信效度良好,是适用于我国的抑郁解释偏向程度测评工具。

ObjectiveTo develop a depressive interpretation bias questionnaire with Chinese culture based on the similarity rating task(SRT),and to test its reliability and validity.MethodsAfter being authorized,the ambiguous paragraphs in cognitive behavior modification errors prospective training items(CBM-I)were translated and screened in the first round,the screened paragraphs combined with the remaining of SRT and the self-written ambiguous paragraphs to form the screening questionnaire of the second round.Fourteen ambiguous paragraphs were selected as the items,and then the ambiguous situation interpretation bias questionnaire was compiled using SRT as the template.The reliability and validity analysis and item analysis were launched after 477 were tested by the questionnaire mentioned before.ResultsA 14-item-formed questionnaire was compiled after 2 rounds of screening,then 5 factors were extracted by exploratory factor analysis,and the cumulative contribution rate was 52.67%.The confirmatory factor analysis showed that the five-factor model fitted well.Cronbach’sαwas 0.613,and split-half reliability was 0.617;Paired t-test was used to test the content validity,which showed significant difference between the target sentences and the foil sentences(t=-12.90,P<0.01).The questionnaire had good criterion validity,regarding the center for epidemiologic studies depression scale(CES-D)in Chinese version as criterion,while the total T score was significantly correlated with the total score of the CES-D(r=-0.224,P<0.01).ConclusionThe interpretation bias questionnaire with ambiguous scenarios is a applicable measurement of depression interpretation bias in China.
