No significant differences between groups were found in the proportion of subjects who knew other OC washers, or had experienced direct associative-learning events prior to onset. Contrary to expectation, significantly more non-OCD subjects had experienced vicarious learning events related to dirt and washing than OCD subjects. However, of note, associative-learning events that took place during episodes of depression were significa...Continue Reading
