Delusions are falsely and firmly held beliefs based on incorrect inferences. In people with psychosis, biases in information processing (e.g., jumping to conclusions biases) are involved in the formation and maintenance of delusions. The Metacognitive Training (MCT) and the Individual Metacognitive Therapy (MCT+) offer a low-threshold treatment alternative to correct cognitive distortions and to ultimately ameliorate psychotic symptoms. The current literature supports the efficacy of MCT, although for acute patients the Individualized version (MCT+) is to be preferred over the group alternative. Interventions with a similar approach, i.e., the Reasoning Training and the Social Cognition and Interaction Training, are introduced. Recent studies suggest using virtual reality to make cognitive distortions more palpable and amenable through corrective experiences in order to reduce psychotic symptoms. The discussed interventions provide an easy-to-integrate option to reduce the treatment gap in psychosis. Even patients with low treatment insight can benefit from the interventions by using psychosis-neutral material.
