MMPI-2 clinical scale differences between dysthymia and major depression.
Though dysthymia is considered less severe and more chronic than major depressive disorder, it is unclear whether the two disorders are truly different. In this study, MMPI-2 scales of 21 patients with dysthymia and 30 patients with major depressive disorder were compared. The average scores on Scales 2, 4, 6, 7, and 8 were in the clinical range for both groups. However, sizable differences between the two groups were found for Scale 1 and Scale 3. Smaller but reliable differences were found for Scale 2 and mean clinical scale T score with major depressives scoring higher on all of these measures. Results indicate that not only is major depressive disorder more severe than dysthymia, but also contains more physical/somatic symptoms than dysthymia.
