Self-Reported ICD-11 Posttraumatic Stress Disorder (PTSD) and Complex PTSD in the General Danish Population

Few national studies have examined the community prevalence of ICD-11 posttraumatic stress disorder (PTSD) and Complex PTSD (cPTSD) symptoms, and their relationship with functioning. A nationally representative Danish sample (n = 689) provided data on trauma exposure. Participants who had experienced at least one traumatic event (n = 470) further provided self-reported data on ICD-11 PTSD and cPTSD, personality, and psychosocial functioning. Mediation analyses and linear regression models investigated the impact of impaired personality functioning, and the severity of PTSD/cPTSD on psychosocial functioning. Despite two-thirds reporting trauma exposure, PTSD and cPTSD prevalence was low (4.7% and 1.9%). Higher severity correlated with lower psychosocial functioning. The influence of impaired personality functioning post-trauma was limited. Replication of findings in clinical samples is warranted.
