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

KIMTP's "harmony in personal relationships" (orderliness) was higher in patients with unipolar depression than in non-clinical subjects, and positively associated with perceived stress, while KIMTP's "social norms" (conscientiousness) was (i) similarly represented across the two groups, and (ii) not correlated with perceived stress. This raises the possibility that, among the core features of TM, concern with orderliness can be considered as a relevant and potentially premorbid personality factor in relation to unipolar depressive disorders.
