Abstract

Background and objectives: This study tested the prognostic value of a two-dimensional trauma-neglect model by
determining clinically relevant change in symptomatology of patients with (comorbid) trauma-related disorders,
dissociative disorders and personality disorders after 2-year follow-up
Methods: Our cohort consisted of 150 patients who were referred to specialized treatment programs for traumarelated
disorders, dissociative disorders or personality disorders. We determined clinically relevant change using
the Relevant Change Index and used logistic regression analysis to test the prognostic value of the trauma-neglect
model.
Results: Our results showed that severity of a trauma-related diagnosis predicted clinically relevant change in
dissociative symptoms, but not in other symptomatology. The number of personality disorders did not predict
clinically relevant change in symptomatology.
Conclusions: We found little support for the prognostic value of the trauma-neglect model, and, contrary to our
expectation, the severity of symptoms did not predict course in a negative way.
