Objective:To explore the application of Symptom Checklist-90 (SCL-90) combined with the Eysenck Personality Questionnaire (EPQ) scors in diagnosis of mental disorders.Methods:This was a cross-sectional study. A total of 2 569 psychiatric outpatients aged 18-35 years who visited the Mental Health Center of Tongji Hospital from 2010-2020 were included in the study. Patients were diagnosed according the International Classification of Diseases 10th Edition (ICD-10). The psychiatric diagnoses included depressive disorders, anxiety disorders, sleep disorders, bipolar disorder, schizophrenia, stress-related and adjustment disorders, and obsessive-compulsive disorder. The diagnostic value of SCL-90 and EPQ scores for psychiatric disorders of patients was examined with univariate multivariate logistic regression analysis, and evaluated with ten-fold cross-validation, and receiver operating characteristic (ROC) curves.Results:Among the subjects, 921 were male (35.9%) and 1 648 were female (64.1%), with a mean age of (26.83±4.59) years.The main mental disorders were depressive disorders (42.1%, 1 081/2 569) and anxiety disorders (31.4%, 806/2 569). Stepwise logistic regression analysis showed that the highest diagnostic efficacy was for sleep disorders [area under the curve ( AUC)=0.795], significantly with obsessive-compulsive, depression, and anxiety factors of the SCL-90 (all P<0.05); followed by depressive disorders ( AUC=0.751), significantly with the female gender, depression, anxiety, and hostility factors of the SCL-90, and the introversion-extroversion factor of the EPQ (all P<0.05). There were moderate diagnostic efficacy for bipolar disorder ( AUC=0.712) and stress-related disorders ( AUC=0.703), and relatively poor diagnostic performance for anxiety disorders and obsessive-compulsive disorder ( AUC=0.702, 0.661). Conclusion:The combination of SCL-90 and EPQ demonstrates moderate to high diagnostic efficacy for common psychiatric disorders, indicating that it may be used in clinical mental health assessments.
