Abstract

OBJECTIVE@#To simplify the psychological domain of Multidimensional Sub-health Questionnaire of Adolescents (MSQA),which includes 39 items and develop the Brief Instrument On Psychological Health of Youths(BIOPHY), as well as to evaluate the predictive validity of the BIOPHY.@*Methods@#A total of 14 221 students were recruited from Shenyang,Xinxiang,Guangzhou,and Chongqing by using multistage stratified cluster random sampling to participate in the study. A combination of item analysis,factor analysis and reliability evaluation were used to screen items and evaluate the questionnaire. Meantime, data from 14 500 adolescents from Shenzhen,Nanchang,Zhengzhou and Guiyang in 2017 were used to develop a cut-off point and to evaluate its predictive validity.@*Results@#On the basis of item analysis,BIOPHY consisted of 15 items. Variance cumulative contribution rate was 57.39%; internal consistency test showed that the total questionnaire Cronbach α coefficient was 0.928. The split-half coefficient of the total questionnaire was 0.909. The 90th percentile of total scores was used as the cutoff point of BIOPHY. The results of multivariate logistic regression analysis showed that students with psychological health symptoms were at significantly higher risk of depressive symptoms (OR=10.53,95%CI=9.28-11.94),suicide ideations (OR=5.77,95%CI=5.15-6.46),suicide plans (OR=6.09,95%CI=5.39-6.89) and suicide attempts (OR=4.80,95%CI=4.04-5.69) than normal counterparts.@*Conclusion@#The BIOPHY is consistent with the evaluation standard of psychometrics. The predictive validity of BIOPHY is good and could be used in the future researches focusing on adolescent mental health.
