We have developed a new treatment method termed ‘association splitting’ that is designed to reduce the intensity and frequency of obsessive thoughts. The method is aimed at people who suffer from obsessive thoughts (e.g., excessive concern about contaminating others; uncertainty about having run over a pedestrian; fear of causing a catastrophe by failing to place things in a particular order or not saying a certain prayer).
