Journal Article

This review of research utilizing the Schizophrenia Cognition Rating Scale (SCoRS) outlines the development, evaluation, validation, and implementation of the SCoRS to assess whether the scale meets the criteria as a functional co-primary as defined by the MATRICS-CT initiative. Interview-based co-primary assessments should be: 1) practical and easy to administer for a clinician or researcher; 2) validated in individuals with schizophrenia; 3) contain the relevant areas of cognition and functioning applicable to schizophrenia; 4) able to assess all phases and severity levels of schizophrenia; 5) capable of monitoring disease progression; 6) minimal burden to patients; and 7) sensitive to assess treatment effects. A review of the literature was conducted to present information on the development, psychometric properties and usage of the SCoRS. Review of the development of the SCoRS followed the parameters outlined for scale development on content expert validation and feedback. The SCoRS shows good psychometric properties in various studies, and demonstrates low burden on clinicians and patients. The items measure global concepts that do not require notable cultural modification, making international use feasible. While multiple performance-based tests in cognition and functional outcomes are available, there is a need for a multi-domain, interview-based assessment of cognitive progression and treatment response in clinical trials. The SCoRS appears to meet many of the criteria for an optimal co-primary measure for schizophrenia cognition clinical trials as defined in the MATRICS-CT initiative.
