Aims: To test the discriminant and concurrent validity of the Spanish version of the Bayer Activities of Daily Living scale (B-ADL) in mild cognitive impairment (MCI) and mild Alzheimer disease (AD). Methods: The B-ADL scale, the Blessed Dementia Rating Scale (BDRS), and the Interview for Deterioration in Daily Living in Dementia (IDDD) were administered to 277 elderly Spanish patients (78 MCI and 199 AD). Correlations between scales were performed, and ROC curves were plotted. Results: In MCI and mild AD discrimination, an area under the ROC curve of 0.84 was found; a cut-off point of 3.3 was proposed with values of 0.81 for sensitivity and 0.72 for specificity. The B-ADL correlated positively to both the BDRS (r = 0.7) and the IDDD (r = 0.8). Conclusion: The B-ADL is a valid and sensitive scale that can be used to discriminate mild AD from MCI.
