This study aims to evaluate the validity and reliability of the Spanish version of ROSA. Patients and methods: 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). Results: ROSA requires 13.8 ± 7.4 minutes 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 (ICC 0.97). Conclusion: The Spanish version of ROSA is a brief, valid, and reliable tool permitting overall evaluation of patients with dementia. Resumen: Introducción y objetivos: La escala Relevant Outcome Scale for Alzheimer's Disease (ROSA) es una herramienta útil para la evaluación y seguimiento de pacientes con demencia. Nuestro objetivo es evaluar la validez y fiabilidad de una versión española de la escala ROSA. Pacientes y métodos: Estudio multicéntrico nacional en el que 39 investigadores han incluido 237 sujetos con enfermedad de Alzheimer (78 en estadio leve, 79 moderado y 80 grave) a los que se les ha aplicado Mini-Mental, Fototest, Neuropsychiatric Inventory (NPI), escala de Blessed y una versión adaptada al español de la escala ROSA. En una submuestra de 40 sujetos se realizó un retest en los 14 días siguientes a la evaluación inicial. La validez de constructo se ha evaluado mediante el coeficiente correlación de Spearman (r), la consistencia interna con el coeficiente alfa de Cronbach (alfa) y la fiabilidad test-retest con el coeficiente correlación intraclase (CCI). Resultados: La escala ROSA se aplica en 13,8 ± 7,4 min y sus resultados están asociados de forma significativa al estadio clínico (leve 116,7 ± 23,1, moderado 92,9 ± 19,8 y grave 64,3 ± 22,6), Mini-Mental (r = 0,68), Fototest (r = 0,63), NPI (r = 0,53) y escala de Blessed (r = –0,80). La escala ROSA muestra una alta consistencia interna (alfa = 0,90) y una excelente fiabilidad test-retest (CCI = 0,97). Conclusión: La versión española de la escala ROSA es un instrumento breve, válido y fiable para la evaluación global de pacientes con demencia.
