Research reportThe relation between affective temperament and resilience in depression: A controlled study
Introduction
Genetic and environmental factors play an important role in the etiology of major depressive disorder. Affective temperament describes the attitudes and behavior of the individual based on the constitutional, genetic and biological factors (Akiskal and Akiskal, 2005a). Individual's affective temperament is one of the variables determining the risk for depression. Akiskal suggested that affective temperament constitutes the basis of mood disorders and described five major affective temperament types: depressive, hyperthymic, cyclothymic, irritable, and anxious (Akiskal and Akiskal, 2005b). Studies conducted within this area suggested that a considerable number of depressive patients have a depressive and anxious temperament (as cited by Angst, 2000). There is a continuity between poles, and there is an association between hyperthymic qualities and good prognosis (Kesebir et al., 2005, Rihmer et al., 2010).
In 1970s researchers observed that some individuals could be able to pass through the normal developmental stages against adverse circumstances, and they started to investigate the neurobiological determinants as well as the psychological determinants in these individuals (Feder et al., 2009, Fadardi et al., 2010, Amico et al., 2011). Resilience has positive effects on neural plasticity and executive functions (Masten, 2001, Buckner et al., 2003, Cicchetti and Blender, 2006, Simeon et al., 2007). Psychological resilience can be described as the ability for adaptation of the individual to adverse environmental conditions (Basım and Çetin, 2011), and is determined by the personal characteristics, familial cohesion and support, and external support systems. The measurement instrument which was developed to assess psychological resilience, (Friborg et al., 2003) examines personal strength, structured style, social competence, family cohesion and social resources sub-dimensions. Personal strength sub-dimension is further divided into two as perception of self and perception of future (Friborg et al., 2005).
We think that the relationship between temperament and resilience is important in psychosomatic diseases and even in somatic diseases. Such that, in asthmatic children, self-esteem was determined to be the predictor of resilience (Lima et al., 2010). The aim of this study was to investigate whether there is a relationship between affective temperament and psychological resilience in depressive patients and if there is a relationship, to determine if this relation differs from that of healthy individuals.

Study sample
Of the individuals who admitted to the outpatient clinic of Erenköy Psychiatry Education and Research Hospital between January 2012 and March 2012 for their regular follow-up assessment and who were being followed regularly for at least 1 year, those who have been diagnosed as major depressive disorder (MDD) and are in remission were recruited to the study. The study sample consisted of 100 consecutive patients (57 females and 43 males) aged between 17 and 77 years of age (mean 32.7±13.2) who
Affective temperament and psychological resilience in MDD and HC groups
The depressive (p=0.012), cyclothymic (p=0.025), irritable (p=0.039), anxious temperament scores (p=0.018) of the depressive disorder cases were higher and psychological resilience (p=0.001) and hyperthymic temperament scores (p<0.001) were lower than those of healthy individuals (Table 1). In depressive disorder cases, the scores from perception of self (p<0.001), perception of future (p=0.042), structural style (p=0.001), and social competence sub-dimensions (p=0.033) of the psychological
Discussion
In this study, the relationship of affective temperament with resilience was compared between depressive and healthy individuals for the first time. In the depression group, the scores for depressive, cyclothymic, irritable, anxious temperaments were higher than those of healthy individuals. Premorbid depressive and anxious temperament in depression is a finding which has been repeated many times (Akiskal and Pinto, 2000). In Akdeniz et al.’s (2004) study similar to our findings, cyclothymic
Limitations
There are methodological difficulties in measuring the temperament and resilience. It is not very simple to differentiate state and trait characteristics between affective temperament and mood disorder. In this study even though the patients were evaluated in the ‘remission’ period according to DSM-IV, it is difficult to distinguish this ‘relative’ remission period from sub-threshold or sub-syndromal forms. Another limitation of this study is that the measurements of temperament and resilience
