RESUMO
Objective:To explore the application of union physio-psycho-social assessment questionnaire (UPPSAQ-70) in screening anxiety and depression in outpatients from general hospital.Methods:A total of 510 outpatients from Peking Union Medical College Hospital from June 2020 to November 2021 were recruited.They were assessed with UPPSAQ-70, self-rating anxiety scale (SAS) and self-rating depression scale (SDS). The internal consistency of the UPPSAQ-70 was tested by Cronbach′s α coefficient.The convergent validity of the UPPSAQ-70 was evaluated by examining correlations with the SAS and SDS.Clinical diagnosis, being considering as the " gold standard" , was used to test criterion validity.Result:The UPPSAQ-70 showed good item characteristics and reliability (Cronbach α=0.947). The UPPSAQ-70 total score showed significant correlations with SAS( r=0.843, P<0.01) and SDS ( r=0.852, P<0.01). The area under the curve (AUC) of the UPPSAQ-70 was 0.875 ( P<0.01), the cut-off value was 65 points with the sensitivity 83.2% and the specificity 75.5%.The AUC of the SAS and SDS was 0.848 and 0.808 respectively(both P<0.001). For the SAS(standard score of 50 as the cut-off value), the sensitivity was 47.3%, and specificity was 92.5%.For the SDS(standard score of 53 as the cut-off value), the sensitivity was 62.9%, and specificity was 86.8%. Conclusion:UPPSAQ-70 has high sensitivity and is more suitable for screening of anxiety and depression in general hospital outpatients.
RESUMO
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: =10 410.4,=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(=0.600)and anxiety(=0.520),the correlation coefficients of other symptoms were below 0.5.The chronbach's between each factor and total score of UPPSAQ-70 was between 0.823 and 0.904,and the Chronbach's 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 was 0.847.Each item of the scale measured between one week was significantly correlated(<0.05). Conclusion UPPSAQ-70 is a good scale for evaluating overall health status and is especially feasible in general hospitals.
