Cognitive behavioral models of obsessive-compulsive disorder (OCD) assume continuity between normal obsessional intrusive thoughts (OITs) and obsessions. However, this assumption has recently been criticized. This article examines this issue using a new instrument (the Obsessional Intrusive Thoughts Inventory, INPIOS) specifically designed to assess the frequency and content of 48 OITs, which was completed by 734 community subjects and 55 OCD patients. Confirmatory factor analysis suggests six first-order factors included in two second-order factors, one containing aggressive, sexual, religious, immoral and repugnant OITs, and the other containing contamination, doubts and checking, symmetry and order, and superstition OITs. This structure integrates the research on OC symptoms and OITs. The INPIOS showed excellent known-groups validity, and it adequately represented obsessions as well as OITs. OCD and community subjects experience OITs representative of all types of obsessional contents. The dimensional structure is discussed in terms of OIT/obsessive-compulsive symptom structures currently proposed.
强迫症（OCD）的认知行为模型假设正常的强迫性侵入性思维（OITs）和强迫观念之间存在连续性。然而，这种假设最近受到了批评。本文使用一种新的工具（强迫症侵入性思维量表，INPIOS）来专门评估 48 种 OIT 的频率和内容，该工具由 734 名社区受试者和 55 名 OCD 患者完成。验证性因素分析表明，六个一阶因素包含在两个二阶因素中，一个包含攻击、性、宗教、不道德和令人反感的 OIT，另一个包含污染、怀疑和检查、对称和秩序以及迷信的 OIT。这种结构整合了 OC 症状和 OIT 的研究。INPIOS 具有出色的已知组有效性，它充分代表了强迫观念和 OIT。强迫症和社区受试者经历的 OIT 代表了所有类型的强迫性内容。该维度结构根据目前提出的 OIT/强迫症状结构进行讨论。
