Evaluating the PCL-5 in China: new insights from its assessments over time and gender invariance

This study validated the novel 8-factor model of DSM-5 PTSD among children in the post-pandemic era and assessed the gender and longitudinal measurement invariance of the PCL-5. The novel 8-factor model of the PCL-5 is the best DSM-5 model of PTSD symptoms and has strict measurement invariance across gender and strong measurement invariance across time. The research results extended the theoretical framework and empirical research on the DSM-5 PTSD novel 8-factor model. Through this analysis, we hope to provide more accurate tools and strategies for the evaluation and intervention of post-traumatic stress disorder in children.
