Melancholic subtyping: a qualitative or quantitative distinction?
M Zimmerman, W Coryell and B Pfohl
Melancholic depressed subjects scored significantly higher than did
nonmelancholic subjects both on the depressive symptoms used and those not
used for melancholic subtyping. The results suggest that DSM-III's
melancholic criteria do not identify a qualitatively distinct subgroup, but
instead reflect illness severity.
