Although obsessive-compulsive disorder (OCD) is usually conceptualized as an anxiety disorder some studies suggested it to be a deficit of impulse control. The purpose of this study was to assess impulsiveness in OCD families and compare it to control families.
Seventy cases and their 139 relatives were compared with 70 controls and their 134 relatives from a German family study on OCD (German Epidemiologic Network for OCD Studies). All subjects were interviewed and diagnosed according DSM-IV criteria and were administered the Barratt Impulsiveness Scale (BIS) and PADUA-Inventory to assess obsessive-compulsive symptoms.
OCD subjects had significantly higher scores of cognitive impulsiveness. However, first-degree relatives of OCD cases and of controls had comparable BIS-11 scores. Significant associations of aggressive obsessions and checking with cognitive impulsiveness were found.
OCD is a severe mental disorder that is characterized by a lack of cognitive inhibition. However, impulsiveness does not represent a familial trait in families of OCD subjects.
尽管强迫症（OCD）通常被视为一种焦虑症，但一些研究表明它是冲动控制缺陷。本研究的目的是评估强迫症患者家庭中的冲动性，并将其与对照组家庭进行比较。
在一项关于强迫症的德国家庭研究（德国强迫症研究流行病学网络）中，将70例患者及其139名亲属与70名对照组及其134名亲属进行比较。所有受试者均根据《精神疾病诊断与统计手册》第四版标准进行访谈和诊断，并接受巴拉特冲动性量表（BIS）和帕多瓦量表评估强迫症状。
强迫症患者的认知冲动得分显著更高。然而，强迫症患者和对照组的一级亲属的BIS-11得分相当。发现攻击性强迫观念和检查行为与认知冲动之间存在显著关联。
强迫症是一种严重的精神障碍，其特征是缺乏认知抑制。然而，冲动性并非强迫症患者家庭的家族特征。
