Abstract
BackgroundTemperamental characteristics have been suggested as potential vulnerability markers or could help differential diagnosis among psychiatric disorders. The current study aimed to explore whether there are specific temperament profiles related to different psychological symptoms, according to the Affective and Emotional Composite Temperament (AFECT) model. MethodsWe used a cross-sectional web-based survey collected from the Brazilian Internet Study on Temperament and Psychopathology (BRAINSTEP). The sample consisted of 16,495 self-selected volunteers assessed with the Affective and Emotional Composite Temperament Scale (AFECTS), Adult Self-Report Inventory (ASRI), and Adult Self-Report Scale (ASRS). ResultsAll unstable affective temperaments (cyclothymic, dysphoric, and volatile) correlated, in different intensities, with all psychiatric symptoms assessed. Cyclothymic temperament was mainly related to borderline personality symptoms. Dysphoric and volatile temperament showed an association with attention deficit hyperactivity symptoms. Melancholic temperament was associated with major depressive symptoms, and euphoric temperament showed a positive correlation with maniac symptoms. Euthymic and hyperthymic temperaments were negatively correlated with all psychiatric symptoms. In addition, the assessment of the emotional traits of temperament showed that high volition, low anger, low sensitivity, and high control are characteristics that are not related to psychopathology. LimitationsThis study had a cross-sectional design, which does not allow an exact inference of cause and consequence. ConclusionsOur results suggest that temperament assessment using AFECT model may be relevant to assess the risk of developing psychological symptoms over the time. These results strengthen the theoretical framework that psychiatric disorders may be manifestations of the extremes of affective temperaments.
