PTSD in ICD-10 and proposed ICD-11 in elderly with childhood trauma: prevalence, factor structure, and symptom profiles

Background : The proposal for ICD-11 postulates major changes for posttraumatic stress disorder (PTSD) diagnosis, which needs investigation in different samples. Aims : To investigate differences of PTSD prevalence and diagnostic agreement between ICD-10 and ICD-11, factor structure of proposed ICD-11 PTSD, and diagnostic value of PTSD symptom severity classes. Method : Confirmatory factor analysis and latent profile analysis were used on data of elderly survivors of childhood trauma (>60 years, N =399). Results : PTSD rates differed significantly between ICD-10 (15.0%) and ICD-11 (10.3%, z =2.02, p= 0.04). Unlike previous research, a one-factor solution of ICD-11 PTSD had the best fit in this sample. High symptom profiles were associated with PTSD in ICD-11. Conclusions : ICD-11 concentrates on PTSD’s core symptoms and furthers clinical utility. Questions remain regarding the tendency of ICD-11 to diagnose mainly cases with severe symptoms and the influence of trauma type and participant age on the factor structure.
