Objective: The aim of this study is to investigate the relationship of Major Depressive Disorder (MDD) and MDD
specifiers with temperament and personality traits with
a perspective focused on Nine Type Temperament Model
(NTTM). Method: 203 healthy participants who are
matched with the 208 MDD participants group between
18-60 years old and in at least eight weeks remission
period and treatment in progress, without an additional
diagnosis were included in the study. Socio-demographic
data form, Nine Types of Temperament Scale (NTTS) and
Temperament Character Inventory (TCI) were applied to
all participants, and in addition, Hamilton Depression
Rating Scale (HDRS) were applied to the subjects with
MDD. MDD specifiers were evaluated using follow-up
data files. Results: According to results, both Nine Type
Temperament (NTT) Model’s types, which are NTT1,
NTT2, NTT3, NTT4, NTT6 and NTT8, and Psychobiological
Personality Model’s dimensions which are consisted of
the cooperation, persistence, harm avoidance and selfmanagement were found to be associated with MDD.
From the point of MDD determinants; anxiety-distressing
characteristics are associated with NTM2, NTM3, NTM6,
NTM9; melancholy characteristics is concerned with
NTT1, NTT5 and NTT6; seasonal characteristics are related to NTT4; mixed features are relevant with NTT4 and
NTT7; and atypical features are associated with NTT5,
NTT7, NTT9. As a result, MDD determinants are found to
be associated with temperament types which are coming from NTTM. Discussion: It is seen that temperament, which constitutes the structural basis of personality, is an effective parameter both in the diagnosis and in
the individual-specific recognition of symptomatology in
MDD patients. In addition, it can be said that temperament can be a discriminating factor in defining MDD
specifiers. The development of temperament-oriented
diagnosis and treatment strategies in future studies may
be beneficial for the practice.
