囤积量表修订版在中国大学生中的修订

Psychometric Properties of the Saving Inventory-revised in Chinese University Students Sample

目的:在中国大学生中修订囤积量表修订版(Saving Inventory-Revised,SI-R)并检验该量表的信效度。方法:采用双盲翻译获得的中文版SI-R对2100名大学生施测,收回有效问卷1979份。进行因素分析以检验其结构效度,用帕多瓦量表、流调中心抑郁量表和Zung焦虑自评量表来检验聚合效度和区分效度,并检验其内部一致性。3-4周后随机抽取229名大学生进行重测,以检验其重测信度。结果:①验证性因素分析表明中文版SI-R不符合原三因素模型;②探索性因素分析后得到两个因子:过分获得-难以丢弃、堆积;③SI-R总量表的Cronabachα系数为0.893,过分获得-难以丢弃分量表和堆积分量表的α系数分别为0.829和0.830;4周后的总量表重测信度为0.561,过分获得-难丢弃分量表和堆积分量表重测信度分别为0.533和0.545;④SI-R总量表与强迫症状、焦虑和抑郁的相关系数分别为0.431、0.355和0.343(P<0.01)。结论:中文版SI-R具有较好的信效度,可以在中国文化下应用。

Objective： To test the reliability and validity of the Saving Inventory-Revised（SI-R）,and view the hoarding in Chinese sample.Methods： 2100 university students were asked to complete a battery of structured questionnaires,including the Chinese version of the SI-R,Padua Inventory（PI）,Zung Self-Rating Anxiety Scale（SAS）,and Center for Epidemiologic Studies Depression Scale（CES-D）.229 of 2100 students were chosen to complete the SI-R again after 3 to 4 weeks.Results： Confirmatory factor analysis of the Chinese version of SI-R couldn＇t confirm the three-factor model.Factor analysis identified 2 factors,excessive acquisition-difficulty discarding,and clutter.The internal consistencies of the SI-R and its subscales were 0.829 to 0.893.The test-retest reliabilities were between 0.533 and 0.561.For the total score of SI-R,the correlation coefficients were 0.431 to obsessive-compulsive symptoms,0.355 to anxiety,and 0.343 to depression（P〈0.01）.Conclusion： The Chinese version of the SI-R appears to be an appropriate instrument for assessing symptoms of compulsive hoarding in Chinese culture.
