Objective:To develop and validate the reliability and validity of the care giver assessment via observation (CGAO) in general hospital .Methods:From July 4, 2022 to June 24, 2023, a total of 120 adult inpatients with somatic diseases in Peking Union Medical College Hospital were selected by cluster sampling. All patients completed the CGAO, union physio-psycho-social assessment questionnaire (UPPSAQ-70) and patient health questionnaire-9 item (PHQ-9) assessment simultaneously. Exploratory factor analysis and item response theory analysis were used to explore the structural validity of CGAO by SPSS 26.0 software.The symptoms items and suicide risk assessed by UPPSAQ-70 and PHQ-9 were used as criteria to verify criterion validity.Results:Through exploratory factor analysis, a single-factor model could be constructed. The analysis based on item response theory suggested that it had a good fit with the single-factor stepwise response model ( χ2/ df=1.307, RMSEA=0.051, CFI=0.986, TLI=0.983). The CGAO total score was significantly positively correlated with the total scores of PHQ-9 and UPPSAQ-70 ( r=0.639, 0.518, both P<0.001). The Cronbach's α coefficient of the CGAO full scale was 0.735. Conclusion:CGAO has good reliability and validity in evaluating mental behavior of patients, and is suitable for early recognition of mental behavior abnormalities of inpatients in general hospitals.

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.
