پرسشنامه شخصیت زاکرمن-کلمن در دو قطبی I و اختلالات II: گزارش مقدماتی

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 (BD II). We administered the Zuckerman–Kuhlman Personality Questionnaire (ZKPQ), 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. 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 to 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. Our study suggests that Impulsive sensation seeking, and its General sensation seeking facet might help to delineate the two types of bipolar disorder.
