Prognostic value of a two-dimensional trauma-neglect model: Two-year course of the Dutch Friesland study cohort

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 Our cohort consisted of 150 patients who were referred to specialized treatment programs for trauma-related 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. 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. 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.
