ObjectiveTo investigate the measurement invariance and the score distribution characters of the 9-item Patient Health Questionnaire (PHQ-9), and to test its feasibility in comparing depression among adolescents of different sexes and ages.MethodsFrom September 2018 to May 2019, 12 241 adolescents aged 10 to 19 years old across 22 primary and secondary schools in Hangzhou were included based on cluster sampling method, and they were investigated by PHQ-9. The measurement invariance was tested by multi-group confirmatory factor analysis. Poisson regression analysis and Logistic regression analysis were adopted to explore the score distribution of PHQ-9 by sex and age.ResultsThe configural, metric, scalar and strict invariances (χ2=2 492.527, df=79, P
