The development and validation of a carer questionnaire to assess cognitive function in neuropsychiatric patients

The CogRisk is a brief carer-rated tool of a patient's cognitive functioning developed for use within a neuropsychiatric setting. It exhibited good concurrent validity, internal consistency, and interrater and intrarater reliability. The CogRisk also demonstrated good sensitivity and specificity for dementia. The CogRisk provides carer information, which complements the clinical assessment and can be used to focus on direct carer interview.
