We’re conducting this research study to learn whether a game-like app, designed to improve cognitive functions (e.g., flexible thinking), can help children ages 8-12 with obsessive-compulsive disorder. We are also trying to learn how the brain works in children with OCD before and after completing the training.

• 8-12 years old
• Struggle with excessive worries and related repetitive behaviors (OCD)
• No developmental disorder, PTSD, substance/alcohol abuse, psychotic disorder, bipolar disorder, eating disorder, or neurological problems

Participation in the study involves the following steps:

• Phone interview: 30 minute phone conversation about your child’s medical and psychiatric history
• Diagnostic evaluation with one of our clinical psychologists (virtual)
• 4 weeks of a cognitive training intervention on an iPad at home. We will loan an iPad for your child to use.
• 3 in-person visits that include puzzles, games, and 2 MRI scans (if your child is able). Visits will take place at the Columbia University Zuckerman Institute in Upper Manhattan.
• 12 weeks of free therapy (CBT) with an expert clinician, if desired (virtual)

Participants can receive up to $400 if they complete the entire study.

There is no cost for your child to participate in our research study or to receive CBT treatment afterwards.
