Background: The category Fluency Test (CFT) is included in the MATRICS consensus cognitive battery for schizophrenia (MCCB). This test has several components that allow the exploration of other cognitive functions and could be related to different symptom profiles.
Methods: a sample of 98 Mexican adolescents was evaluated with the CFT and the following components were analyzed: total words, errors, clusters, switching, related words, and categories.
Early-onset psychosis (EOP) is among the leading causes of disease burden in adolescents. Negative symptoms and cognitive deficits predicts poorer functional outcome. A better understanding of the association between negative symptoms and cognitive impairment may inform theories on underlying mechanisms and elucidate targets for development of new treatments.

- A study on cognitive impairment in Mexican adolescents with schizophrenia used the MATRICS Consensus Cognitive Battery to assess improvements after six months of antipsychotic treatment.
- Results indicated that while most cognitive domains showed improvement, social cognition did not, and female adolescents performed better in specific areas like attention and visual learning.
- The findings suggest that demographic and clinical characteristics influence cognitive improvements, highlighting the need for tailored treatment approaches.
Introduction: Treatment guidelines for schizophrenia represent a standard way to manage patients, especially in countries with limited staff resources. However, they have not been compared on their efficacy with treatment as usual, despite adult studies suggesting they can be more effective.
Methods: Inpatient and outpatient adolescents with schizophrenia were randomly allocated to be either treated according to a guideline-based treatment ( n = 43) or treatment as usual ( n = 44).
Background: The Personal and Social Performance (PSP) scale is a widely used tool to evaluate adults with schizophrenia; however, more studies are needed regarding its usefulness in the assessment of adolescent patients, since the evaluation of their functioning could require adaptations according to development.
Objective: To examine construct validity, convergent validity, internal consistency and interrater reliability of the PSP in a sample of Mexican adolescents with schizophrenia.
Methods: A total of 40 patients with a DSM-IV diagnosis of schizophrenia or schizophreniform disorder were evaluated with PSP, CGAS, PANSS and the MATRICS battery.
