Experimental: Cognitive Remediation Therapy
Cognitive Remediation Therapy -Frontal/Executive Program (Delahunty)- (Wykes & Reeder, 2005)
Behavioral: Cognitive Remediation Therapy
The program has a duration of 40 sessions (one hour of duration), with two sessions for week during four months. It is carried out individually and utilizes paper and pencil tasks. The main technique utilized is the scaffolding (to provide strategies when the patient cannot carry out the task and to withdraw him when he is yet able of doing it alone) in a context of learning without errors.
Other Name: Cognitive rehabilitation, cognitive training
Active Comparator: Psychoeducation
Symptom Management Module from the University of California. Liberman & Kopelowicz (1995)
The program has a duration of 40 sessions (one hour of duration), with two sessions for week during four months. It is carried out individually and utilizes teaching information and coping skills and neuropsychological issues are not addressed.
Other Name: Coping strategies, skills training
No Intervention: Healthy Controls
- BDNF (change from baseline serum BDNF levels) [ Time Frame: Baseline, 1 month and 4 months ]Change Measurements of serum BDNF levels will be carried out by personnel blind to subjects' group assignment. Platelet and serum samples will be diluted with diluent included in the R&D Human BDNF Quantikine Enzym Linked Immunosorbent Assay (ELISA) kit (Yasuhito et al. 1987).
- Symptoms (Change from baseline in Positive and Negative Syndrome Scale (PANSS) scores) [ Time Frame: Baseline and 4 months ]Change from baseline in Positive and Negative Syndrome Scale (PANSS) scores at time 16 weeks
