Abstract INTRODUCTION We assessed the accuracy of the Amsterdam Instrumental Activities of Daily Living Questionnaire (A‐IADL‐Q) for clinical staging in Swedish primary care. METHODS Participants from the Swedish BioFINDER Primary Care study were included. Discriminative performance of the A‐IADL‐Q was evaluated using receiver operating curves. Multinomial and linear regression models assessed associations among A‐IADL‐Q scores, clinical stage, demographics, cognition, and comorbidities. RESULTS Among 623 patients, 148 (23.8%) had subjective cognitive decline (SCD), 274 (43.9%) mild cognitive impairment (MCI), and 201 (32.3%) dementia with a mean (standard deviation) age of 76.7 (7.3). The area under the curve (95% confidence interval) for discriminating between SCD versus MCI/dementia was 0.89 (0.86–0.91) and for SCD/MCI versus dementia 0.89 (0.87–0.92). Age ( β = −0.25), Mini‐Mental State Examination ( β = 0.91) and Montreal Cognitive Assessment ( β = 0.57), but no other demographics and comorbidities, were associated with the A‐IADL‐Q. DISCUSSION The A‐IADL‐Q may help primary care physicians determine clinical stage and shows promise for use to adequately refer patients to secondary or tertiary care.
