ITreatOCD: Predicting the Efficacy of Internet-based Cognitive Behavioral Therapy from Changes in the Neurobiological Correlates of Emotion Regulation in Obsessive-compulsive Disorder
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.
• Primary diagnosis of current OCD according to the fifth Diagnostic and Statistical Manual of Mental Disorders
• YBOCS score ≥ 16
• Psychotropic medication, if stable for at least 2 months prior to inclusion and if the dosage is maintained thoughout the study
• Have the resources to access the online intervention (internet access; computer or tablet)
