Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
study intervention
The 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.
Metacognitive training game
In the fantasy world "Macu'ta", players explore the world by walking around with an avatar in order to find the puzzles and proceed in the game. The intervention consists of 4 different puzzles. Unbeknownst to the player, the first pieces of evidence of each puzzle are often misleading, i.e. indicate the wrong solution, such that hasty decisions are punished. Players receive immediate feedback and are shown the correct response after submitting their solution, as well as explicit cues that educate them on the value of making adequately informed decisions. The order of the puzzles is fixed for each player, but different per session.
control intervention
The control intervention consists of a puzzles focused exclusively on dexterity and accuracy.
Control games
In the fantasy world "Macu'ta", players explore the world by walking around with an avatar in order to find the puzzles and proceed in the game. The control intervention consists of 4 different puzzle games requiring exclusively dexterity and accuracy (i.e., not including any metacognitive elements). The order of the puzzles is fixed for each player, but different per session.
