What this Trial Is About
Researchers are investigating two types of psychological interventions for adults with Obsessive-Compulsive Disorder (OCD) who experience distressing, future-oriented intrusive thoughts and images. The study aims to determine whether imagery rescripting or exposure therapy is more effective in reducing these distressing images and symptoms. This research uses a single case experimental design to compare these approaches. Participants will be randomly assigned to receive either imagery rescripting followed by imaginal exposure or imaginal exposure followed by imagery rescripting. Both interventions are psychological techniques delivered over a 12-week treatment period. The study does not involve any drug treatments and focuses on the effects of these psychological therapies. Throughout the 12 weeks, participants will be assessed using various scales measuring OCD symptoms and the impact of future-oriented images, including the Obsessive Compulsive Inventory, Yale-Brown Obsessive-Compulsive Scale, Impact of Future Events Scale, Florida Obsessive Compulsive Inventory, and Visual Analogue Scales. The study team will monitor progress from the start to the end of treatment to evaluate the interventions' effects.
