OCRD Trial Summary

This trialwill assess a new computerized intervention to improve response inhibition and reduce symptoms of OCD, trichotillomania, and skin picking disorder.

Who is the study for?
This trial is for adults aged 18-60 with moderate to severe obsessive-compulsive or related disorders (OCRD), such as OCD, trichotillomania, or skin picking disorder. Participants should have certain levels of symptoms measured by specific scales and a deficit in response inhibition. They must not have psychotic disorders, bipolar disorder, schizophrenia, high suicide risk, MRI contraindications, substance use issues, severe ADHD or recent changes in psychotropic meds.Check my eligibility
What is being tested?
The study tests a computerized intervention called Response Inhibition Training (RIT) against placebo training to see if it can improve the brain's ability to stop inappropriate responses in people with OCRD. Participants will undergo multiple sessions and be evaluated through clinical assessments and brain imaging before and after training and at a one-month follow-up.See study design
What are the potential side effects?
Since this trial involves computerized cognitive training rather than medication or invasive procedures, side effects are minimal but may include eye strain from screen time or discomfort during MRI scans.

OCRD Trial Design

2Treatment groups
Experimental Treatment
Placebo Group
Group I: Response Inhibition Training (RIT)Experimental Treatment1 Intervention
Response Inhibition Training (RIT) is a about 40-level computer game designed to offer systematic practice of RI. Participants use the computer keyboard and mouse to respond to the demands of trials that are designed to offer training on response inhibition abilities, including suppressing pre-potent but irrelevant stimuli and responses. Each training session will last approximately 45 minutes. All participants will be offered a minimum of 8 sessions. Throughout training, we will continually monitor their behavioral RI index (= stop signal reaction time; SSRT) using a stop-signal task. If a participant's Index SSRT fails to reach a criterion-level reduction (i.e., approximately 1 SD) after the standard 8 session intervention, the RIT intervention will be extended up to 16 sessions until the criterion-level improvement in behavioral RI is attained.
Group II: Placebo Training (PLT)Placebo Group1 Intervention
This training condition is designed to serve as an appropriate control condition for RIT, by providing no active ingredient of RI training components, while maintaining the overall training materials and structure similar. Similar to RIT, PLT uses the same task materials and a similar 40-level game structure. However, PLT will present simple RI-irrelevant visual judgment tasks to avoid changing RI-relate processes. The number of 45-min training sessions will be determined by their counterpart RIT participants through a yoked-control design.
