ABSTRACT

The purpose of this study was to investigate the relationship among temperaments, childhood trauma, and multidimensional impulsivity. This study, in particular, examined how the sub-dimensions of temperament and the types of childhood trauma affect according to each dimension of impulsivity. A total of 172 psychiatric patients completed the questionnaires including Korean Temperament and Character Inventory (TCI), Childhood Trauma Questionnaire (CTQ), and UPPS-P Impulsive Behavior scale. Those who diagnosed with schizophrenia spectrum disorder, bipolar disorder, intelligence disability, and neurocognitive disorder were excluded. Childhood physical abuse was significantly correlated with all five dimensions of impulsivity(Positive Urgency, Negative Urgency, Sensation Seeking, Lack of premeditation, Lack of perseverance). The relationship between other types of childhood trauma and impulsivity was distinguished according to the each dimension of impulsivity. After controlling for demographic variables(gender and age), the results of a hierarchical multiple regression analysis showed that both temperaments and childhood sexual abuse were significantly predicted level of Urgency, whereas only temperaments affected the other dimensions of impulsivity. The clinical implications and limitations of our findings were also discussed.
