The mediating role of emotion regulation in transdiagnostic cognitive behavioural therapy for emotional disorders in primary care: Secondary analyses of the PsicAP randomized controlled trial

Targeting certain maladaptive emotion regulation strategies (worry, rumination, suppression, negative metacognition) as mediators for treatment with TD-CBT could reduce emotional symptoms and improve well-being. Negative metacognition was the most transdiagnostic strategy, whereas an adaptive strategy such as reappraisal was not a mediator. Thus, maladaptive emotion regulation strategies are key mediators in transdiagnostic therapy for emotional disorders in primary care.
