This study aims to investigate the mediating role of rumination in the relationship between perfectionism and psychological distress, by proposing a cognitive-behavioral intervention targeting rumination. This intervention aims at decreasing - or even neutralizing - the effect of the mediator and then examining how this decrease impacts the relationship between perfectionism and psychological distress. A randomized, concurrent, multiple-baseline single-case design will be applied.
