RESUMO
The current study validated the youth-reported Pediatric Symptom Checklist-Youth (PSC-Y) using a Chinese youth sample (N = 20,996). The factor structure, measurement invariance, and criterion validity were examined. First, factor analysis documented that the correlated three-factor structure, including externalizing problems, internalizing problems, and attention problems fit the data best, which aligns with the prior factor structure of the PSC-Y in other settings (e.g., teacher ratings). In addition, measurement invariance was established across gender and age groups. The latent mean differences revealed that middle and high school students and females reported more internalizing and attention problems than elementary students and males. Additionally, high school students and females were less likely to report externalizing problems than elementary students and males. Finally, the criterion validity of the PSC-Y was established using external scales assessing subjective wellbeing and prosocial behavior. Teachers, school administrators, and school psychologists can utilize the results of this study to more precisely identify youth at risk for psychosocial problems.
