思维压抑量表:中文版的结构、信度及效度

White Bear Suppression Inventory:Structure,Reliability and Validity of the Chinese Version

目的:在大学生群体中对思维压抑量表(White Bear Suppression Inventory,WBSI)进行修订并考察其信效度。方法:采用方便取样方法,对样本一的125名大学生施测WBSI及贝克抑郁问卷,以检验该量表的效度,并随机选取其中33名学生,在初测4周后进行了重测;对样本二的383名大学生施测WBSI、宾州忧虑问卷、事件影响量表-修订版及想法行为混淆量表。对样本三的334名大学生施测WBSI、帕多瓦量表、特质焦虑问卷及多元个人传统性量表-宿命迷信分量表。结果:对样本一的探索性因素分析获得WBSI的3个因素(闯入性思维、思维压抑和转移注意),3个因素可解释总变异的52.4%;对样本二和样本三的验证性因素分析显示,三因素模型拟合最好(χ2/df=3.45,CFI=0.91,TLI=0.89,RMSEA=0.07,SRMR=0.06)。WBSI总分的内部一致性系数为0.87,重测信度为0.59;3个因素的内部一致性系数分别为0.83、0.66和0.70。女性WBSI得分均显著高于男性。效标效度分析表明WBSI与抑郁(r=0.29)、特质焦虑(r=0.42)、创伤后应激障碍症状(r=0.42)、强迫症状(r=0.30)及广泛性焦虑症状(r=0.44)呈显著正相关。本研究还探索了迷信在OCD症状的发展维持中的作用,结果支持迷信导致了思维压抑从而导致了OCD症状(χ2/df=5.04,CFI=0.88,TLI=0.82,RMSEA=0.11,SRMR=0.08)。结论:思维压抑量表的中文修订版具有良好的信效度。

Objective： To test the reliability and validity of the Chinese version of White Bear Suppression Inventory（WBSI） among a Chinese student sample.Methods： A convenience sample of 125 college students completed the WBSI and Beck Depression Inventory;a randomly selected subsample of 33 students participated in the retest in 4 weeks.A second sample of 383 college students completed the WBSI,Penn State Worry Questionnaire,Impact of Event Scale-Revised,and Thought-Action Fusion Scale.A third sample of 334 college students completed the WBSI,State-Trait Anxiety Inventory,Padua Inventory,and a measure of Chinese superstition.Results： EFA results revealed 3 factors（intrusive thoughts,thought suppression and self-distraction）,which accounted for 52.4% of the total variance.CFA results provided support for a 3-factor model（χ2/df=3.45,CFI=0.91,TLI=0.89,RMSEA=0.07,SRMR=0.06）.Internal consistency and test-retest coefficients for the WBSI-total were 0.87 and 0.59 respectively.WBSI-total scores were significantly higher for female participants.Criterion-related validity results revealed positive significant correlations between WBSI and depression（r=0.29）,trait-anxiety（r=0.42）,PTSD symptomology（r=0.42）,OCD（0.30）,and GAD（r=0.44）.SEM results also provided support for a model wherein thought suppression mediates the relationship between superstition and obsessive-compulsive symptoms.Conclusion： The Chinese version of the WBSI is found to have good reliability and validity.
