简易版疾病认知问卷中文版在躯体化障碍患者中的应用

Application of the Chinese version of brief illness perception questionnaire in patients with somatoform disorder

目的：引进简易版疾病认知问卷（brief illness perception questionnaire,B-IPQ）并探讨其在躯体化障碍患者中的效度和信度。方法：对方便取样法选取的237例躯体化障碍患者实施B-IPQ测评并进行项目分析、探索性因素分析、验证性因素分析和内部一致性检验;同时施测抑郁自评量表（self-rating depression scale,SDS）和焦虑自评量表（self-rating anxiety scale,SAS）以检验效标关联效度;2周后对其中95例再测B-IPQ以检验重测信度。结果：项目分析显示各条目得分与总分的相关系数介于0.556~0.842;探索性因素分析与验证性因素分析表明B-IPQ具有单一维度特性;B-IPQ总分与SAS、SDS得分均呈正相关（r=0.640、0.616）。内部一致性Cronbach’sα系数为0.831,重测信度为0.931。结论：B-IPQ中文版具有较好的鉴别力和信效度,符合心理测量学的要求,可用于躯体化障碍患者疾病认知的测评。

Objective：To introduce the Chinese version of brief illness perception questionnaire（B-IPQ）and to investigate its psychometric attributes in patients with somatoform disorder. Methods：Totally 237 patients with somatoform disorder were chosen to complete the Chinese version B-IPQ;item analysis,exploratory factor analysis,internal consistency checking,etc were conducted. At the same time,they were asked to complete the SDS and SAS to test the criterion related validity. Ninety-five of the 237 patients were asked to complete the Chinese version B-IPQ again after 2 weeks to test the test-retest reliability. Results：Item analysis showed that correlation coefficients of each item score and total score were 0.556-0.842;there were significant differences in each item scores and total score between high score group and low score group;the Cronbach＇s α coefficient was 0.831;the test-retest reliability of the scale and each entry were 0.931,0.771-0.849. Exploratory factor analysis showed that the B-IPQ had a single dimension scale characteristic. Correlations coefficients with SAS,SDS scores were 0.640,0.616. Conclusion：The Chinese version of B-IPQ has good psychometric attributes to assess the illness perception status of patients with somatoform disorder and can be taken as an effective instrument.
