The National Adult Reading Test (NART) is widely used to estimate premorbid ability in clinical neuropsychology. However, there is accumulating evidence that NART performance can be impaired in some neurological disorders. This program implements a multiple regression equation that can be used to predict an individual's NART performance from demographic variables (age, sex, years of education, and occupational code). The demographic estimate of NART performance is compared with the obtained score to evaluate the likelihood that the NART will provide a valid estimate of premorbid ability. The equation was built in a healthy UK sample (N= 659).
