Abstract:

The validity of ICD-11 Posttraumatic Stress Disorder (PTSD) and Complex PTSD (CPTSD), as measured by the International Trauma Questionnaire (ITQ; Cloitre et al., 2018) has been supported in many factor analytic and mixture modelling studies. There is, however, a paucity of research investigating the latent structure of the ITQ using factor mixture modelling (FMM). FMM was applied to data collected from a nationally representative sample of U.S. adults (N  =  1834). FMM results demonstrated strong support for a two-factor second-order model with four qualitatively distinct latent classes: a ''PTSD class'', a ''CPTSD class'', a ''DSO'' (Disturbances in Self-Organisation) class and a ''low symptoms class''. Sexual abuse increased likelihood of membership to the ''CPTSD'' (OR = 3.22) and physical abuse decreased likelihood of membership to the ''PTSD'' (OR = 0.51). Trauma exposure in adulthood predicted ''PTSD'' and ''CPTSD'' class membership. The ''CPTSD class'' was characterised by higher levels of psychopathological co-morbidities and poorer psychological wellbeing compared to all other classes. Results provide additional support for the validity of PTSD and CPTSD as measured by the ITQ.
