Metacognitive Training as a serious game: A new approach for the treatment of delusions

Psychotic disorders influence multiple aspects of everyday functioning and quality of life. In the past, there has been growing interest in psychotherapeutic interventions such as cognitive behavioural therapy (CBT) as an adjunctive treatment in patients with psychotic disorders. Based on CBT, metacognitive training for psychosis has been developed as an evidence-based form of psychotherapy for the treatment of psychotic disorders.

The goal of our research is to evaluate the efficacy of a therapeutic video game (“Ma’cuta”) that incorporates elements from metacognitive training on delusions and cognitive biases such as the jumping to conclusions (JCT). In our game, patients play the character “Ellen” and move through a fantasy world, where different tasks have to be completed. The immersive and entertaining nature of video games could be a great advantage for patients in whom motivational and social cognition deficits may reduce adherence with appointments or the willingness to participate in therapy groups.Our research aims to provide insight into feasibility and usefulness of therapeutic games in the treatment of psychotic disorders in order to support further development of treatment.
