综合生理-心理-社会评估问卷的信效度分析

目的 对综合生理-心理-社会评估问卷(UPPSAQ-70)进行信效度分析。方法 选取2013年4月至2018年7月就诊于北京协和医院、由医生开具心理评估、并在心理评估室同时完成UPPSAQ-70和症状自评量表(SCL-90)评估的患者,固定因子数为8个因子和3个因子,进行探索性因子分析;采用Amos 23.0对原8因子模型、8因子模型-修订、原3因子模型、3因子模型-修订和单因子模型进行验证性因子分析;以SCL-90的各因子为校标,计算因子之间的相关系数,验证区分效度。对2018年7月完成UPPSAQ-70评估的患者进行重测,检验重测信度。 结果 UPPSAQ-70的8因子模型包含:情绪、焦虑与疲劳、睡眠、躯体不适、性功能、快乐和满意度、疑病和社交焦虑;3因子模型包含:心理维度症状、生理维度症状和社会维度症状。验证性因子分析提示,8因子修订模型具有较好的拟合程度(χ ²=10 410.4,df=1862,RMSEA=0.07,CFI=0.753,NFI=0.715)。8因子模型以SCL-90为校标,除情绪量表与抑郁(r=0.600)、焦虑(r=0.520)相关度相对较高,其他症状相关度较低(r<0.5)。量表各因子的Chronbach’s α系数在0.823~0.904之间,删除各条目后全量表的Chronbach’s α系数在0.954~0.956之间。该量表的重测信度为Chronbach’s α系数0.847,两次重测各项均显著相关(P<0.05)。 结论 UPPSAQ-70是良好的评估人的整体健康状况的量表,适宜综合医院使用。

Psychometric Evaluation of the Union Physio-Psycho-Social Assessment Questionnaire

Objective To validate the Union Physio-Psycho-Social Assessment Questionnaire(UPPSAQ-70)and test its validity and reliability.Methods From April,2013 to July,2018,patients were asked to finish the computer evaluation of UPPSAQ-70 and Symptom Checklist 90(SCL-90)in Peking Union Medical College Hospital(PUMCH).Confirmatory factor analysis(CFA)was conducted on the SPSS 17.0,and the number of fixed factors was 8 factors and 3 factors.Amos 23.0 was used to verify the original 8-factor model,8-factor revision model,3-factor model,3-factor revision model,and single-factor model.Each factor of SCL-90 was used as the calibration standard to calculate the correlation coefficient between factors.The retest reliability was tested by the outpatients in PUMCH in July,2018.Results Exploratory factor analysis indicated that the 8-factor revised model included:depression,anxiety and fatigue,sleep,physical discomfort,sexual function,happiness and satisfaction,hypochondria,and social anxiety.The 3 factors revised model included that:psychological,physiological and social dimension.Confirmatory factor analysis indicated that the 8-factor modified model was superior to the 3-factor model and the single-factor model: χ ²=10 410.4,df=1862,RMSEA=0.07,CFI=0.753,and NFI=0.715.With SCL-90 as the standard criteria,except the low correlation coefficient between emotional scale and depression(r=0.600)and anxiety(r=0.520),the correlation coefficients of other symptoms were below 0.5.The chronbach’s α between each factor and total score of UPPSAQ-70 was between 0.823 and 0.904,and the Chronbach’s α coefficient of the whole scale was between 0.954 and 0.956 after each item was deleted.The retest reliability of the scale of 32 participants Chronbach’s α was 0.847.Each item of the scale measured between one week was significantly correlated(P<0.05). Conclusion UPPSAQ-70 is a good scale for evaluating overall health status and is especially feasible in general hospitals.
