This randomized controlled trial examines the effects of a mobile-based gamified combined cognitive bias modification (CBM-C) intervention on obsessive-compulsive symptoms, obsessive beliefs, attentional and interpretation biases, depressive symptoms, and psychological distress. The gamified CBM-C condition is compared to a standard mobile-based CBM-C and a placebo control condition. All interventions are delivered via a mobile application. Assessments are conducted at baseline, post-intervention (week 4), and 3-month follow-up.
