Five-factor Personality Traits And Their Relationships With The Emotional States In Bipolar Ⅰ And Ⅱ Disorders

Background:Patients with bipolar disorder have tendencies of higher impulsivity and sensation seeking, they might contribute differently to the emotional states of bipolar Ⅰ (BD Ⅰ) and Ⅱ (BDⅡ).Methods:We administered the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ), one of the five-factor models, the Plutchik-van Praag Depression Inventory (PVP), the Mood Disorder Questionnaire (MDQ), and the Hypomania Checklist (HCL-32) in 23 patients with BD Ⅰ,22 BD Ⅱ, and 64 healthy volunteers.Results:Both BD Ⅰ and Ⅱ scored higher on ZKPQ Impulsive sensation seeking (and its Impulsivity facet), Neuroticism-anxiety and Aggression-hostility, and on PVP and HCL-32 scales than controls did; BD Ⅰ scored higher on MDQ and General sensation seeking facet than controls did. Compared with BD Ⅱ, BD Ⅰ scored higher on Impulsive sensation seeking (and General sensation seeking) and on MDQ. Moreover, General sensation seeking predicted MDQ, and Activity predicted HCL-32 in BD Ⅰ. Aggression-hostility predicted HCL-32 in BD Ⅱ. General sensation seeking predicted MDQ and HCL-32, and together with Neuroticism-anxiety, predicted PVP in controls.Conclusion:Our study suggests that Impulsive sensation seeking and its General sensation seeking facet might help to delineate the two types of bipolar disorder.
