Cognitive deficits are a core feature of the first psychotic episode patients and could be an obstacle to functional ability. Cognitive stimulation could be a promising method to surpass neuropsychological deficits.

–to implement an online training protocol to stable first psychotic episode outpatients;

–to assess adherence to the intervention;

–to measure neurocognitive, psychopathological and functional outcomes pre- and post-training.

To investigate the feasibility of an online-based resource for cognitive stimulation (COGWEB®) and explore possible benefits in different domains.

Fifteen patients were enrolled from the Early Psychosis Intervention Program (PROFIP) at the Department of Psychiatry of Santa Maria Hospital, Lisbon. The training consisted on 30-40-minute online sessions performed every weekday during 6 months at home. Assessments were performed at baseline and after program completion and included: psychopathological scores; personal and social functioning scores; Clinical Global Impression and a neuropsychological battery.

Every participant had some kind of impairment on baseline. Mean training time was 36 h. Six patients left the program before completion (half of them because they got employed). The program showed overall good feasibility and safety with no reported significant psychiatric occurrences or hospitalizations. Results regarding final neuropsychological, psychopathological and functioning showed a tendency for stability or improvement on an individual case analysis.

Our results show that cognitive training using an online-based stimulation software is a feasible intervention for first-episode psychosis patients with possible benefits for this population. However, results should be analyzed very carefully because of different participant trajectories and of study limitations.
