ABSTRACT
In 2018, Complex Post Traumatic Stress Disorder (CPTSD) was officially recognized as a distinct syndrome in the International Classification of Diseases, 11th Revision (ICD-11). This recognition aimed to differentiate between neurotic disorders secondary to stressful situations and somatoform disorders, and disorders specifically associated with stress. The inclusion of CPTSD in the ICD-11 marked the culmination of two decades of research focused on understanding its symptoms, treatments, and risk factors. However, despite the progress made, a comprehensive meta-analysis to elucidate the specific risk factors and impact on the development of CPTSD is still lacking. The objective of this article is to conduct such a meta-analysis. A total of 24 studies were selected for analysis, and the findings revealed several key risk factors associated with the development of CPTSD. The main risk factor identified is having experienced sexual abuse in childhood (k = 12; OR = 2.880). In addition, childhood physical abuse (k = 11; OR = 2.841), experiencing emotional neglect during childhood (k = 5; OR = 2.510), physical abuse throughout life (k = 8; OR = 2.149) and being a woman (k = 13; OR = 1.726) were also significant risk factors.
