In the present study, the structure of obsessive-compulsive symptoms was investigated by means of the Padua Inventory (PI). Simultaneous Components Analysis on data from obsessive-compulsives (n = 206), patients with other anxiety disorders (n = 222), and a non clinical sample (n = 430) revealed a five-factor solution. These factors are: (I) impulses; (II) washing; (III) checking; (IV) rumination; and (V) precision. Forty-one items were selected as measure of these factors. The reliability for the five subscales, assessing each of the five factors, was found to be satisfactory to excellent. Four subscales (washing, checking, rumination and precision) discriminated between panic disorder patients, social phobics and normals on the one hand and obsessive compulsives on the other. The Impulses subscale discriminated between obsessive-compulsives on the one hand and normals on the other, but not between obsessive-compulsives and social phobics or panic patients. Some evidence in support of the construct validity was found. The Padua Inventory-Revised (41-items) appears to measure the structure of obsessive compulsive symptoms: The main types of behaviours and obsessions as seen clinically are assessed by this questionnaire, apart from obsessional slowness.
在本研究中，通过帕多瓦量表（PI）对强迫症状的结构进行了调查。对强迫症患者（n = 206）、其他焦虑症患者（n = 222）和非临床样本（n = 430）的数据进行同步成分分析，得出了一个五因素解决方案。这些因素分别是：（I）冲动；（II）洗涤；（III）检查；（IV）沉思；（V）精确。选取了41个项目作为这些因素的测量指标。评估这五个因素的五个分量表的信度被发现令人满意至优秀。四个分量表（洗涤、检查、沉思和精确）一方面在惊恐障碍患者、社交恐惧症患者和正常人之间，另一方面在强迫症患者之间进行了区分。冲动分量表一方面在强迫症患者和正常人之间进行了区分，但在强迫症患者与社交恐惧症患者或惊恐障碍患者之间没有区分。发现了一些支持结构效度的证据。修订后的帕多瓦量表（41项）似乎能够测量强迫症状的结构：除了强迫性迟缓外，该问卷评估了临床上所见的主要行为和强迫观念类型。
