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.
在用于 melancholic 亚型分类的抑郁症状以及未用于该分类的症状方面，抑郁性抑郁患者的得分均显著高于非抑郁性患者。结果表明，《精神疾病诊断与统计手册》第三版（DSM-III）的抑郁性标准并未识别出一个质上不同的亚组，而是反映了疾病的严重程度。
