Test–retest reliability and criterion validity of the Chinese version of CBCL, TRF, and YSR

Background: Psychometric properties of the Chinese version of CBCL, TRF, and YSR were understudied. This study aimed at examining their test–retest reliability and criterion validity. Methods: Three Chinese community and clinic samples were recruited in Hong Kong. The parents, teachers, and youths respectively completed the CBCL, TRF, and YSR. Results: The Chinese CBCL, TRF, and YSR were test–retest reliable and valid. However, there was score/case attenuation at retest. CBCL and TRF appeared to screen externalizing and ADHD problems better, while YSR screened internalizing problems better. Conclusions: Clinicians should be cautious about score/case attenuation at retest while using CBCL, TRF, and YSR to chart patients’ progress. They should also recognize their different strengths in screening various disorders.
