Effects of a Cognitive Rehabilitation Program: a Neurocognitive Study

Schizophrenia is known to be associated with cognitive dysfunction which increasing evidence suggests has consequences for functional adaptation and which cause difficulties in social re-integration after hospitalization. The investigators propose a large scale, multicentric study (7 centres from the Hermanas Hospitalarias del Sagrado Corazón de Jesús network) aimed at answering outstanding questions concerning the effectiveness of cognitive estimulation therapy for schizophrenic cognitive impairment. Specifically, the study will examine a) issues related to the size of the effect compared to treatment as usual and compared to a control intervention; b) generalizability of improvement to cognitive function and social cognition in daily life; and c) the durability of therapeutic gains after the end of treatment. 192 patients with chronic schizophrenia will be randomly assigned to one of three treatment conditions: a computer- assisted cognitive estimulation program (n=64), non-structured time on computer (n=64) and treatment as usual (n=64). A battery of neurocognitive tests of memory and executive function, including 'ecologically valid' measures, will be administered by blind evaluators at baseline, after 6 months of cognitive estimulation, and after 6 months follow-up. Symptoms, social functioning and self-esteem will be also be assessed at baseline, after the treatment and at follow-up.

  • estimated premorbid intelligence quotient (IQ) in the normal range
  • chronic illness (i.e. duration ≥two years)

Treatment and study plan

Computer-assisted cognitive training

Behavioral

Treatment lasted six months. The CRT and CC conditions consisted of biweekly sessions of 45 minutes. Patients in both conditions trained in groups of up to 8, supervised by a single person. The CRT and CC groups were scheduled at different times. The same personnel supervised both treatment conditions. All supervisors were trained by the coordinator of the study in the technical management of the two conditions.

Other names: Computer-assisted cognitive training (CRT)

Computerized active condition

TAU: Patients in this condition participated in their (individually variable) daily rehabilitative activities. Patients allocated to the other two conditions also participated in these activities.
