Brief Summary

The project aims to evaluate the efficacy of a therapeutic video game that incorporates elements from metacognitive training on delusions and jumping-to-conclusions in patients with psychotic disorders.

Detailed Description

The study is an international, multicenter study and is being conducted in Switzerland (University of Basel) as well as in Germany (University of Lübeck). A total of 36 participants will be included. The estimated duration of the study is 15 months. All participants play a video game from the genre "Third Person Adventure". A character is navigated through a fantasy world using a keyboard and mouse. In the fantasy world, "stations" in the form of glowing gems are sought where players have to solve different tasks.

Participants are randomized to receive either the therapeutic video game with metacognitive training content or another video game with attention and memory tasks ("control intervention"). The control intervention does not include metacognitive tasks. Metacognitive training is an approach for the treatment of psychotic disorders, particularly delusions. The focus of metacognitive training is on thought distortions (so-called "cognitive biases") that are more pronounced in people with psychosis. The control intervention includes easily understandable, playful tasks. The intervention will take 4 appointments within 2 weeks.

control interventionControl gamesThe control intervention consists of a puzzles focused exclusively on dexterity and accuracy.
study interventionMetacognitive training gameThe intervention consists of a puzzle adventure game, in which players have to explore the fantasy world "Macu'ta". The puzzles are based on Metacognitive Training for Psychosis (MCT), an intervention using playful, entertaining exercises to increase awareness of reasoning biases in patients and 'sow the seeds of doubt' through corrective ('aha!') experiences. The tasks will address reasoning biases associated with the emergence and maintenance of delusions.

Change of delusion severityChange from pre- to post-intervention (4 weeks)

Item P1 of the Positive and Negative Syndrome Scale (PANSS). Min score = 1, max score = 7, where lower scores indicate better outcome.

Secondary Outcome Measures

Fish Task: change of probability threshold to decisionChange from pre- to post-intervention (4 weeks)

Probability threshold to decision, assessed with the 'Fish task'

Change of total PANSS ScoreChange from pre- to post-intervention (4 weeks)

Total score on the Positive and Negative Syndrome Scale. Lower scores indicate better outcome.

Change of delusional convictionChange from pre- to post-intervention (4 weeks)
