Cognitive assessment

Show Summary Details

Preview

Psychometric methods based on classical test theory have permitted the development of reliable and valid tests assessing a wide range of intellectual and cognitive functions. Test results assist in formulation and diagnosis, guide rehabilitation and management, provide baseline measures to detect change, and generally assist clinical decision-making regarding such issues as capacity. Tests and assessment procedures are being further developed so as to improve their ecological validity, enabling better prediction of real-life behaviour and functioning.
