Relationship between the core features of Tellenbach's Typus Melancholicus and unipolar depressive disorders: a cross-sectional study.

Purpose: One of the most consistent models investigating the relationship between premorbid personality and depression was described by Tellenbach. According to this model, concern with orderliness, conscientiousness, hyper/hetereonomia and intolerance of ambiguity are the core features of Typus Melancholicus (TM). Previous studies showed a relationship between unipolar depression and TM.
