El punto de corte de mejor rendimiento para DCL-a fue < 21 y para demencia leve < 20 sensibilidad/especificidad de 75/82% y 90/86%, respectivamente. La prueba fue eficaz y válida para la detección del DCL-a (ABC = 0,903) y demencia leve (ABC = 0,957) menos eficaz en DCL no-a (ABC = 0,629). La consistencia interna fue buena (α de Cronbach 0,772), la fiabilidad interevaluador muy buena (coeficiente de correlación de Spearman 0,846 ) y la fiabilidad intraevaluador (test-retest) fue 0,922 bilateral (p < 0,001). Los promedios ± desviación estándar de edad y escolaridad fueron 73 ± 6 y 11 ± 4, respectivamente, sin diferencias significativas entre los grupos. MétodosĬiento setenta y dos individuos agrupados según diagnóstico clínico basado en Clinical Dementia Rating (CDR) en: deterioro cognitivo leve tipo amnésico (DCL-a, n = 24), DCL no-amnésico (DCL-na, n = 24), demencia leve (n = 20) y 104 cognitivamente sanos fueron evaluados con el MoCA-S y Mini-Mental test de Folstein (MMSE) como prueba de contraste, para determinar la validez discriminativa del MoCA-S. ObjetivoĮvaluar las propiedades psicométricas y la validez discriminativa del MoCA-S en adultos mayores de Santiago de Chile. The MoCA-S1-2 is a short, easy-to-use, and useful test for diagnosing aMCI and mild dementia.Įxisten pocas validaciones de la versión en español de la prueba Montreal Cognitive Assessment (MoCA-S) en Latinoamérica. The MoCA-S1-2 showed significantly greater discriminant validity than the MMSE for differentiating aMCI from dementia. The level of education had a great impact on scores: as a result, 2 points were added for patients with less than 8 years of schooling and one point for patients with 8-12 years of schooling (MoCA-S1-2). The optimal cut-off points for aMCI and mild dementia were < 21 and < 20, respectively, with sensitivity and specificity rates of 75% and 82% for aMCI and 90% and 86% for mild dementia. The MoCA-S was found to be an effective and valid test for detecting aMCI (AUC = 0.903) and mild dementia (AUC = 0.957) its effectiveness for detecting naMCI was lower (AUC = 0.629). 01), and high intra-rater reliability (test-retest reliability coefficient: 0.922 P <. The MoCA-S displayed good internal consistency (Cronbach’s α: 0.772), high inter-rater reliability (Spearman correlation coefficient: 0.846 P <. Mean age and years of schooling were 73 ± 6 and 11 ± 4 years, respectively, with no significant intergroup differences. Participants were evaluated with both the MoCA-S and the Mini-Mental State Examination (MMSE) to determine the discriminant validity of the MoCA-S. Methodsġ72 individuals were grouped according to their clinical diagnosis based on the Clinical Dementia Rating (CDR) scale as follows: amnestic mild cognitive impairment (aMCI n = 24), non-amnestic MCI (naMCI n = 24), mild dementia (n = 20), and cognitively normal (n = 104). To evaluate the psychometric properties and discriminant validity of the MoCA-S in elderly patients in Santiago de Chile. Few studies have validated the Spanish-language version of the Montreal Cognitive Assessment (MoCA-S) test in Latin American populations.
