Abstract: Amyotrophic lateral sclerosis (ALS) is characterized functional decline, traditionally measured by the ALS Functional Rating Scale-Revised (ALSFRS-R). The Rasch-Built Overall Amyotrophic Lateral Sclerosis Disability Scale (ROADS) is an alternative comprehensive, detailed functional disability measure for people with ALS (pwALS), not yet translated to Spanish. The aim of this study was to translate and validate the Spanish ROADS. 53 Spanish speaking pwALS were recruited. They completed the ALSFRS-R and Spanish ROADS. Reliability (internal consistency, intra-class correlation) and validity (ALSFRS-R total and item-total correlations) were determined. The Spanish ROADS internal consistency reliability was excellent (Cronbach’s standardized alpha = 0.94), the test-retest reliability intra-class correlation value was 0.93. There was a strong significant correlation between the Spanish ROADS and ALSFRS-R totals (rs(52) = .89, p < .001). Additionally, the ALSFRS-R subscales and ROADS items correlations showed domain-to-item specific expected significant correlations. The Spanish ROADS is a psychometrically robust, valid and reliable measure for quantifying functional disability for pwALS.
