Brief Summary
In the current study, the investigators will characterize obsessive-compulsive disorder (OCD) patients and healthy controls with a comprehensive clinical and neuroimaging assessment, focusing on the basic psychological processes related and on the neurobiological underpinnings of emotion regulation (ER). After a baseline assessment, the investigators will implement an internet-based cognitive behavioral therapy (iCBT) protocol and assess its efficacy on the modulation of ER and OCD severity. Specifically, the investigators will (1) examine to what extent the iCBT intervention modulates ER and the associated neurobiological mechanisms and (2) identify candidate biomarkers of successful treatment response.
