Trent Obsessive-Compulsive Disorder Study – We Want to Hear Your Story!

Posted on: June 20th, 2023

Researchers at Trent University are seeking participants for an online study designed to investigate symptom progression in obsessive-compulsive disorder (OCD).

Study Overview
The study has two parts. The first is an online survey designed to establish a baseline of current symptoms and experiences. The second is a private, personalized, online meeting with a research team member to expand on the questions from Part I. The online meeting format allows participants to speak freely and directly to a researcher to make sure that experiences are fully heard and understood. Participation in either part is completely voluntary, and participants will not be asked to share any information that is beyond their comfort level.

Inclusion Criteria
Participants must be 18 years of age or older and have been formally diagnosed with obsessive-compulsive disorder.

Study Purpose
OCD is known for expressing very different symptoms from person-to-person that can also change over time. These differences can make the process of diagnosing and treating the disorder very difficult. Effort has been made to organize symptoms using different categories and criteria, with questions emerging about their utility in diagnosing and treating the disorder. Our study investigates the longitudinal stability of two leading models of symptom organization and how certain life events, personality factors, or treatment approaches, may influence their course over time.
