This study aimed to assess the factor structure of early and late onset OCD. Additionally, cluster analysis was conducted in the same sample to assess the applicability of the factors. 345 participants were assessed with Yale Brown Obsessive Compulsive Scale symptom checklist. Patients were classified as early onset (onset of symptoms at age ≤ 18 years) and late onset (onset at age > 18 years) OCD depending upon the age of onset of the symptoms. Factor analysis and cluster analysis of early-onset and late-onset OCD was conducted. The study sample comprised of 91 early onset and 245 late onset OCD subjects. Males were more common in the early onset group. Differences in the frequency of phenomenology related to contamination related, checking, repeating, counting and ordering/arranging compulsions were present across the early and late onset groups. Factor analysis of YBOCS revealed a 3 factor solution for both the groups, which largely concurred with each other. These factors were named as hoarding and symmetry (factor-1), contamination (factor-2) and aggressive, sexual and religious factor (factor-3). To conclude this study shows that factor structure of symptoms of OCD seems to be similar between early-onset and late-onset OCD.
本研究旨在评估早发性和晚发性强迫症的因素结构。此外，在同一样本中进行了聚类分析，以评估这些因素的适用性。345 名参与者接受了耶鲁-布朗强迫量表症状清单的评估。根据症状出现的年龄，将患者分为早发性（症状出现年龄≤18 岁）和晚发性（症状出现年龄>18 岁）强迫症。对早发性和晚发性强迫症进行了因子分析和聚类分析。研究样本包括 91 例早发性和 245 例晚发性强迫症患者。早发组男性更为常见。早发组和晚发组在与污染相关、检查、重复、计数和排序/安排强迫相关的现象学频率方面存在差异。两组 YBOCS 的因子分析均显示出 3 个因子解，这两个因子解基本一致。这些因子分别命名为囤积和对称（因子 1）、污染（因子 2）和攻击、性和宗教因子（因子 3）。综上所述，本研究表明，早发性和晚发性强迫症的症状的因素结构似乎相似。
