The depressive disorder is one of the most frequent mental disorders, which is often associated with severe dysfunctionality. Personality traits are considered as important factors for the occurrence of depressive disorder. To determine the specificity of personality dimensions as predictive factors of depressive disorder. TCI-R temperament and character inventory — revised was used as the main research instrument. There are specific personality traits expressed through high scores of Harm Avoidance and low scores of Self —Directedness traits as predictive factors related to an incidence of the depressive disorder.
The results of this study show that certain personal traits, and more specific HA and SD, are with a specific predictability of the depressive disorder. Cloninger has developed personality theory as the biopsychosocial model of temperament and character, which is based on biological, neurophysiological, psychological and genetic studies [ 1 - 3 ]. It describes the relationship between personality biogenetic structure and mental disorders.
Cloninger proposed that person can be considered as a multidimensional construct that includes lower and higher levels of personal functioning through the features of temperament and character. Cloninger conceptualises personality as the combination of two interrelated domains: temperament and character traits.
Temperament is reflecting heritable and neurobiologically based differences in behavioural conditioning, and character traits reflecting both neurobiological and sociocultural mechanisms of semantic and self-aware learning.
Those domains are hypothesised to interact as a nonlinear dynamic system regulating the development of human psychological functions [ 4 , 5 ]. Personality system was proposed as the seven-factor model of temperament and character. Cloninger et all. Cloninger hypothesised that temperament traits are determined genetically and correlated with dopaminergic, serotonergic and noradrenergic activities, with early life manifestation. It is discussed that they have strong relations with the older cortico-striatal and limbic systems that regulate habits and skills.
Temperament is largely genetically determined and configures automatic behavioural responses, which are related to vulnerability to a wide range of mental disorders. These character dimensions present persons mental self-government and can measure the presence of personalitydisorder.
However, some authors have suggested that they are related with recently evolved regions of the brain - such as the frontal, temporal, and parietal neocortex - that regulate learning of facts and propositions. However, Cloninger has later acknowledged that the relationship between neurotransmitters and temperament is more complex than the originally postulated [ 4 ].
Novelty was seeking: Novelty seeking NS is explained as the tendency toward exploratory activity and intense excitement in response to novel stimuli, linked with low basal dopaminergic activity. Harm avoidance: Harm avoidance HA is explained as a tendency to respond intensely to aversive stimuli and to avoid punishment, linked with high serotonergic activity. Reward dependence: Reward dependence RD , is explained as the tendency to respond intensely to that was originally hypothesised to be linked with low basal noradrenergic activity.
Self —Directedness: Self —Directedness SD refers to the person the ability to adjust behaviour according to the selected goals and values. It is the source of a sense of personal integrity and self-esteem. Cooperatives: Cooperativeness C is defined as the ability of the person to accept and identify with other people. Self — Transcendence: Self-Transcendence refers to the interest people have in searching for something elevated, something beyond their individual existence [ 23 ].
The relationship between affective disorders and personality is complex. Personality features may predispose an individual to, result from, or modify clinical symptoms of a depressive illness, or be an attenuated expression of a Self —Directedness n affective disorder [ 6 ]. Several clinical studies indicate that personality traits can be used to predict further vulnerability to mood disorders [ 7 - 10 ].
Cloninger suggests that the interaction of all dimensions of personality may influence vulnerability to depression [ 11 ]. These studies demonstrate that high-HA in relation with other personal characteristics, among other is associated with the onset of a depressive disorder, and familial vulnerability to unipolar depression is associated mostly with high HA and low SD [ 12 - 15 ]. In recent years TCI is widely used for determination of the personal characteristic of people with depression.
Result in many studies show higher levels of HA and ST and a lower level of SD and C, in comparison with the control groups [ 11 , 17 - 20 ]. Studies indicate that several clinical features specific to hit the highway connect such as recurrence of mood changes, and comorbidity with other psychiatric conditions associated with personality characteristics.
The presence of comorbid anxiety disorders is most frequent, compared to control groups [ 13 ]. In line with the most research in this field, the results show that as the most effective dimensions of personality with the distinctive predictability of occurrence of depressive disorder can serve HA and SD dimensions of personality.
Depressed patients exhibit higher harm avoidance scores as well as lower self-directedness scores as compared to healthy controls in most of the studies, as well as in this study.
Regarding other traits, results differ, and there are different types of analysis. Some authors are finding lower C and higher ST and RD, but with conclusions that these scores are likely to state dependent. Svrakic has concluded that high scores of SD and C are more common in people with mood disorders [ 21 ].
Hi LU has concluded that trait depression and anxiety were linked to high harm avoidance and low self-directedness, and trait depression was linked to high self-transcendence [ 23 ]. Other studies have shown that antidepressants are changing personality characteristics after successful therapy outcome, and some studies even showed that temperament might influence response rate to antidepressant treatments in patients with major depression [ 24 ].
The main purpose of this study is to determine the role of specific personality traits as predictors of depressive disorder. For depression measurement: The Beck Depression Inventory is a question multiple-choice self-report inventory. It is widely used the questionnaire to assess the presence and severity of depressive symptoms. They assessed four points scale of 0 to 3, based on the weight of each question. Beck classifies the total score as follows: 0 -9 normal range; minimal depressive symptoms; moderate symptoms and severe symptoms [ 25 , 26 ].
It is intended to assess the individual differences of the four temperaments Harm Avoidance, Novelty Seeking, Reward Dependence and Persistence and three character higher-order dimensions Self-Directedness, Cooperativeness and Self- Transcendence. Each higher order dimension if further divided into sub-scales. TCI has been proven internally consistent and factor-analytically valid tool for clinical and legal samples [ 27 - 31 ]. Data was analysed using SPSS version Examined group EG : A set of questionnaires was twice applied to the participants of the examined group — inpatients in the University Clinic of Psychiatry Skopje, diagnosed with the recurrent depressive disorder F Control Group CG : 20 individuals — volunteers, without the history of mental illnesses or relatives with mental illnesses.
Their mean age was Informed consent was signed by all participants form both groups. This research was conducted at the University Psychiatric Clinic - Skopje. The obtained results show that there are significantly relevant differences of certain personality traits between the both groups of respondents, indicating that HA high scores and SD low scores are characteristic of people with a depressive disorder, and therefore predictors for its occurrence Table 1.
Our findings show that the human personality consists of multiple dimensions that interact as a complex adaptive system, not as a set of individual components. The results, which are in line with most studies in this field, are conclusive that certain personality characteristics could be assessed as predictors of depressive disorder. Scores of dimensions Harm Avoidance HA and Self —Directedness SD presented significant differences in scores between EG and CG, which do not change significantly even after treatment, suggesting that these characteristic values for people with depression.
This study has defined high scores of HA and low scores of SD as predictors of the occurrence of depressive disorder. Namely, after antidepressant treatment, scores of HA and SD remain close to values before treatment, which means that high HA and low SD are typical for people who suffer from a depressive disorder. The results of TCI inventory indicated that HA is an emotional marker for vulnerability to depressive disorder and SD represents the marker for executive functions for protection.
These conclusions are in line with findings of many scientific types of research; confirming that high scores of HA and low scores of SD are significant predictors of vulnerability to depressive disorder [ 15 ]. Harm Avoidance HA is a characteristic of a person who is associated with inhibition or interruption of a certain kind of behaviour in any frustrated situation. Persons who have high scores of HA are characterised d by uncertainty, light tiredness, seclusion, pessimism, and is described as fearful, inhibited, with the constant anticipation of damage, while a person with low scores is described as calm, uninhibited, carefree, energetic, and optimist [ 2 ].
Taking into account the total values of HA for all groups, it can be concluded that people with high levels of HA are at increased risk of depressive disorder, or are characteristic of a population that already had depressive episodes. With high levels of the personality, characteristic HA can be described tendency toward negative emotions such as fear, shyness and constant concern.
These personality traits are characteristic of a person with a higher risk of the depressive disorder. These values are accepted as a general characteristic of people with the depressive disorder. However, the mood state of the depressive patient should be taken into consideration because of possible bias. The results of relevant studies suggest that elevated HA are due to personality characteristics, and are characteristic of people prone to depression.
The obtained results are also leading to conclusions that low levels of SD can be a risk factor for depression; however is not clear how low SD can cause depression. SD as a feature of personality involves the ability of individuals to control their behaviour, with the high capacity for adaptability to new requirements or conditions, reinforcing behavioural patterns aimed at satisfying individual targets and selected values [ 2 - 3 ].
Persons who have high scores for SD are characterised by responsibility, maturity, self-respect, initiative, determination for achievement, with a high degree of insight. On the other hand, people who have low scores for SD are characterised by a sense of inferiority, lack of initiative, proneness to wishful thinking, blaming others for their mistakes. These characteristics are very similar to the description of the depressive person, so it is presumable that low SD scores are linked occurrence of depression.
Such findings are stressing conclusions that those subjects with high SD are more able to cope effectively and successfully with difficult life situations or to adapt accordingly and to use their defence mechanisms to deal with the stressor situation [ 18 , 32 - 34 ]. Novelty seeking NS is associated with the initiation of interest for new events or things, and of the appropriate action. NS median values after treatment of the depressive patients are closer to the values of the control group [ 35 ].
This indicates that this personality characteristic is probably changeable as a result of a depressive disorder and that due to the process of recovery values are closer to those of the control group. This aspect, along with the results of the correlation of the total value of NA negative correlation with Beck scale indicates that this personality characteristic can be an indicator of the success of antidepressant treatment rather than a predictor of depression.
Reward dependence RD is characterised by a tendency toward dependence on signals of reward, especially verbal signals of social approval, social support and present mood state. As the results of other relevant research, results of our study show that the values of RD are correlated with depressive mood [ 36 ].
A change in scores of RD reflects the present mood state, and it can be assumed that the various expressions of depressive symptoms showed different influence on personality characteristics. RD is negatively correlated with Beck scale, which shows that reducing the Beck scale scores is correlated with an increase of RD scores.
Cooperation C is the dimension of the character which is defined as the ability of a person identification and acceptance by others [ 11 ]. The results obtained from personality dimension C, during can be concluded that its score is dependable of mood state, and average values after antidepressant treatment are closed to control group. This result is leading to the conclusion that C is not having the predictability of occurrence of depression.
The results obtained in this study show that P does not qualify as any of predictability of occurrence of depressive disorder nor the success of antidepressant therapy. Certain changes are interpreted as variables dependent on the current affective state, i. Self-transcendence ST is the dimension of the character that relates to the spiritual aspects of the person. The differences in the values of self-overcoming feature did not show statistically significant difference [ 11 ]. Obtained results are not leading to the conclusion that this personality characteristic lacks specificity for any predictability of occurrence, nor are dependable of the mood state, i.
However, beside general conclusions which indicate that HA and SD may be a relevant predictors of the occurrence of depressive disorder, this kind of interpretation or conclusion can not be generalised. Namely, a very important circumstance is referred to the relationship with other personal dimensions. Many authors suggest interplay with other features of personality such as NS, RD or ST, can be of more important influence than singular dimension itself.
In conclusion, the results of this study show that certain personal traits, and more specific HA and SD, are with a specific predictability of the depressive disorder.

Objective: Fibromyalgia FM patients may present psychopathology and some characteristic personality traits that may affect their adaptation to the disease. The aim of this paper was to study the relationship between personality dimensions according to the psychobiological model of Cloninger and the presence of psychopathology. Materials and methods: The study sample consisted of 42 patients with FM and 38 pain-free controls. Results: A higher proportion of clinical psychopathologic syndromes CPS was observed in the FM group than in the control group, the most prevalent being anxiety disorder and dysthymia. Conclusions: Patients with FM have a high probability of anxious-depressive-type psychopathologic alterations. Their vulnerability to these conditions may be determined by personality traits. The SD character dimension may have implications for therapy, as low SD is associated with the presence of psychopathology and with a low capacity to cope with the disease.
Louis, South Euclid Avenue, St. Depression study has seen a revolutionary change since the introduction of personality concept of temperament and character proposed by C. Harm avoidance, a temperament domain, and self-directedness, a character domain, are the two that are often referred to as correlates of clinical depression. Yet other domains of temperament and character have been studied as a correlate of depression. Data from epidemiological studies provided an insight into the effects of age and gender on the chronological changes of temperament and character.
