The 338-item MMPI-2-RF (Ben-Porath & Tellegen, 2008) uses a
true–false response format to measure 50 overlapping dimensions
of adult psychopathology: 3 higher order symptom scales, 9 broad
clinical scales, 5 scales measuring pathological aspects of personality,
5 somatic scales, 9 internalizing scales, 4 externalizing scales, 5
interpersonal scales, 2 interest scales, and 8 validity scales. In the
current study, participants completed the MMPI-2-RF in group format
within two weeks of the other measures.
