By understanding processes contributing to the development of PTSD, we can target these processes early-on using evidence-based interventions to help individuals recover from traumatic experiences and protect against (or mitigate) long-term psychiatric problems. our study aimed to examine if emotion dysregulation in the aftermath of a traumatic event predicts PTSD symptoms 3 months later, even when considering other risk factors for PTSD.
