Clusters of phenomena were obtained by two clustering techniques, using the form and content of obsessions and compulsions. Significant clusters which emerged involved washing, checking, thoughts of past, and embarrassing behaviour. Depression occurred as a discrete cluster. Eighty-nine per cent of subjects could be fitted into at least one cluster; over half could be fitted into only one cluster. Washers and checkers made up more than half of the sample studied.
通过两种聚类技术，利用强迫观念和强迫行为的形式与内容，得到了现象集群。出现的显著集群包括洗涤、检查、对过去的想法以及尴尬行为。抑郁作为一个离散集群出现。89%的受试者至少能归入一个集群；超过一半的受试者只能归入一个集群。洗涤者和检查者占所研究样本的一半以上。
