Effectiveness of the Combination of Water Aerobics and Metacognitive Training

1-hour session of water aerobics per week, for 3 months. A specialized trainer will carry out water aerobics sessions and will focus on motor coordination, strength and cardiovascular workout.

1-hour session of MCT per week, for 3 months. A trained psychologist will carry out the MCT sessions. MCT addresses the most common cognitive biases in psychosis. Each session will focus on one topic, such as attributional style, jumping to conclusions, theory of mind, emotion recognition, memory or empathy.

Patients in this arm will participate in both in water aerobics and MCT sessions, once a week for each intervention.
