The ICD-11 proposes two related stress and trauma disorders, PTSD and Complex-PTSD (C-PTSD). A diagnosis of C-PTSD requires that in addition to the PTSD symptoms, an individual must also endorse symptoms in three major domains: (1) affective disregulation, (2) negative self-concepts, and (3) interpersonal problems. This study aimed to determine if the naturally occurring distribution of symptoms in three groups of traumatised individuals (bereavement, sexual victimization, physical assault) were consistent with ICD-11 PTSD and C-PTSD specification. The study also investigated whether these groups differed on a range of other psychological problems. Latent class analyses consistently found that a 3-class solution was best. The classes were 'PTSD only', 'Complex PTSD', and 'Low PTSD/CPTSD'. These classes differed significantly on scores on measures of depression, anxiety, dissociation, sleep disturbances, somatization, interpersonal sensitivity, and aggression. The 'Complex PTSD' class in the three samples scored highest on all the variables, with the 'PTSD only' class scoring lower and the 'Low PTSD/CPTSD' class the lowest. This study provides evidence to support the diagnostic structure of CPTSD, and indicated that CPTSD is associated with a broad range of other psychological problems.
