NCT ID NCT06357364
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested two online cognitive behavior therapy (CBT) programs to help university students who struggle with chronic procrastination. 293 participants were split into groups receiving one of two therapy types or placed on a waiting list. The goal was to see if the therapy reduces procrastination and changes brain activity measured by fMRI or EEG, focusing on improving self-regulation.
