This study explored the subjective experiences of individuals with autogenousand reactive forms of obsessions in obsessive-compulsive disorder. Past studieshave found greater levels of shame, stigma, and concealment for thoseexperiencing lesser-known forms of OCD, particularly those that deal with sexualthemes. This study looked at what words most differentiated (i.e, keynessanalysis) these subtypes. In addition, the word networks (i.e., collocates) of thewords that most differentiated the subtypes were examined. The keywords“sexual” and “POCD” had the strongest keyness in the autogenous corpus.Contamination and checking had the strongest keyness in the reactive corpus.The collocates of the node words in the autogenous corpus show a focus on theintrusive thoughts themselves, whereas the collocates in the reactive corpus focuson performing compulsions such as checking. Limitations, clinical implications,and future research recommendations are discussed.
