Distinct correlates of post-traumatic stress disorder and subthreshold post-traumatic stress disorder considering a broad range of adverse experiences [PDF]
European Journal of PsychotraumatologyBackground: While not all trauma-exposed individuals develop post-traumatic stress disorder (PTSD), many experience severe and enduring emotional effects. In Singapore, no study has investigated the prevalence and correlates of subthreshold PTSD and PTSD
