Title: Efficacy of a Cognitive Remediation Treatment in Adolescents With Schizophrenia Spectrum Disorders
Brief Summary: Cognitive Remediation Therapy (CRT) can enhance cognitive performance in schizophrenia improving functional outcome. But most of the studies have involved participants who are in average in their mid 30s, and little is known about the efficacy of CRT in adolescents with early-onset schizophrenia (EOS). The aim of this study is to investigate efficacy of CRT in improving cognitive performance and functional outcome in adolescents with EOS. We expect to find that CRT improves cognitive and functional outcomes in adolescents with schizophrenia.
