The purpose of this study was to construct a Swedish version of the National Adult Reading Test (NART‐SWE), a test for assessment of premorbid IQ, and to investigate its validity and reliability on healthy controls and patients with mild Alzheimer's disease. As Swedish pronunciation rules are fixed, NART‐SWE was constructed using loan words. NART‐SWE has satisfactory psychometric properties: Inter‐rater and retest reliability as well as internal consistency are very high. The NART‐SWE demonstrates face validity. In addition, high correlation with IQ was obtained. A significant model emerged when using NART‐SWE to predict IQ. Furthermore, no significant differences were observed when comparing performance for healthy controls’ with that of patients with Alzheimer's disease on NART‐SWE. It does appear that reading of irregular words is intact in mild Alzheimer's disease.
