OBJECTIVE
This study investigated the comorbidity of obsessive compulsive disorder and obsessive compulsive personality disorder with the dieting disorders. A comorbid sample was examined in order to test the hypothesis that obsessive compulsive symptoms and personality are premorbid in these patients.
METHOD
Sixty-eight inpatients (35 with anorexia nervosa and 33 with bulimia nervosa) were assessed for DSM-III-R Axis 1 and Axis 11 obsessive compulsive psychopathology using the Composite International Diagnostic Interview (CIDI) and the Personality Disorders Inventory (PDE), respectively.
RESULTS
Twenty-one percent of the group met criteria for a diagnosis of obsessive compulsive disorder. Thirty-seven percent of anorexia nervosa patients were comorbid for obsessive compulsive disorder compared to only 3% of bulimia nervosa patients. In most, the obsessive compulsive disorder had predated the dieting disorder. Nineteen percent of patients were found to have premorbid obsessive compulsive personality disorder.
DISCUSSION
This study supports the assumption of obsessive compulsive comorbidity within the dieting disorders and provides empirical support that this obsessionality is a premorbid characteristic.
目的
本研究调查了强迫症及强迫型人格障碍与饮食失调症的共病情况。对共病样本进行检查，以检验强迫症症状和人格在这些患者中为病前特征这一假设。
方法
分别使用复合国际诊断访谈（CIDI）和人格障碍问卷（PDE），对68名住院患者（35名神经性厌食症患者和33名神经性贪食症患者）进行DSM-III-R轴I和轴II强迫症精神病理学评估。
结果
该组中21%符合强迫症诊断标准。神经性厌食症患者中37%与强迫症共病，而神经性贪食症患者中仅有3%。大多数情况下，强迫症早于饮食失调症出现。19%的患者被发现有病前强迫型人格障碍。
讨论
本研究支持饮食失调症中存在强迫症共病的假设，并提供了实证支持，即这种强迫观念是病前特征。
