[Functional outcome in schizophrenia: relation to the MATRICS consensus cognitive battery]

Area of Science:

• Psychiatry and Neuroscience
• Clinical Psychology
• Rehabilitation Medicine

Context:

• Functional outcome assessment is a key concern in schizophrenia research, particularly within the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) initiative.
• Evaluating functional outcomes aims to reflect cognitive improvements measured by the MATRICS Consensus Cognitive Battery (MCCB).
• Schizophrenia treatment research necessitates robust measures of daily living and community integration.

Purpose:

• To identify optimal measures for assessing functional outcomes in schizophrenia.
• To establish functional capacity as a co-primary measure for the MCCB.
• To explore performance-based and interview-based approaches for measuring functional outcome and its predictive validity for community adjustment.

Summary:

• The study identified functional capacity as a co-primary measure for the MCCB and explored various assessment methods.
• The Modified Social Functioning Scale/Social Adjustment Scale for MATRICS-Psychonomic and Standardization Study (SFS/SAS for MATRICS-PASS) was introduced to predict social functioning.
• The research considered functional performance as a predictor of patients' ability to adjust to community living.

Impact:

• This work refines the assessment of functional outcomes in schizophrenia, enhancing the ability to measure treatment efficacy.
• The validated measures, like the Modified SFS/SAS for MATRICS-PASS, can improve predictions of social functioning and community adjustment.
• Addressing the translation of these measures is vital for global application and comparative research in schizophrenia treatment.
