Recent studies showed that the ICD-11 C-PTSD is associated with considerable individual and social consequences. This study focused on the persistence and psychological predictors of C-PTSD. We analyzed longitudinal survey data from a sample of Hong Kong adults (N = 230) with an interval of approximately six months. Participants completed standardized self-report measures of C-PTSD and various psychological factors (including self-criticism, self-compassion, ruminative response, event centrality, and experiential avoidance) at both timepoints. Over 80% of participants with probable C-PTSD at baseline remained to meet the criteria for PTSD/C-PTSD at follow-up, while over 50% of participants with probable PTSD at baseline remitted at follow-up. Participants with probable C-PTSD were characterized by greater use of mental health services at both timepoints. Additionally, hierarchical multiple regression showed that, among a variety of psychological factors, experiential avoidance was the only significant predictor of PTSD (β = 0.271, p =.001) and disturbances in self-organization (DSO) (β = 0.200, p =.011) symptoms, after controlling for baseline symptom severity and treatment usage. This study shows that C-PTSD persists over time and its symptoms are predicted by experiential avoidance. More efforts are needed to prevent and address C-PTSD in the community. We also offer insights into the management of trauma-related disorders. [ABSTRACT FROM AUTHOR]
