Structural personality organization as assessed with theory driven profile interpretation of the dutch short form of the MMPI predicts dropout and treatment response in brief cognitive behavioral group therapy for axis I disorders.

We investigated the validity of theory driven profile interpretation of the MMPI (Hathaway & McKinley, 1943) Dutch Short Form (DSFM; Eurelings-Bontekoe, Onnink, Williams, & Snellen, 2008) as a measure of personality organization (PO) in a naturalistic follow-up study among 576 psychiatric outpatients receiving brief cognitive behavioral group therapy. Results showed that this assessment method was useful in predicting dropout as well as treatment response. Patients with a latent psychotic PO profile and a manifest low-level borderline organization profile were 3 times more likely to drop out than patients with other PO profiles.
