This study aims to evaluate the validity and reliability of the Spanish version of ROSA. Spanish multicentre study involving 39 researchers and including 237 patients with Alzheimer disease (78 mild, 79 moderate, and 80 severe). The patients were tested with the following: Mini-Mental State Examination (MMSE), Fototest, Neuropsychiatric Inventory (NPI), Blessed dementia scale, and a Spanish-language version of ROSA. A subsample of 40 subjects was retested in the 14 days following the initial evaluation. The construct validity was evaluated with the Spearman correlation coefficient (r), internal consistency with Cronbach's alpha (alpha), and test-retest reliability with the intraclass correlation coefficient (ICC). ROSA requires 13.8±7.4minutes to administer and its results show a significant association with the clinical stage of AD (mild, 116.7±23.1; moderate, 92.9±19.8; and severe, 64.3±22.6), and with results on the MMSE (r=0.68), Fototest (r=0.63), NPI (r=0.53), and Blessed dementia scale (r=-0.80). ROSA shows high internal consistency (alpha=0.90) and excellent test-retest reliability (ICC0.97). The Spanish version of ROSA is a brief, valid, and reliable tool permitting overall evaluation of patients with dementia.
