ABSTRACT
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.
