A-10 High Score Multivariate Base Rates for the Spanish-Language NIH Toolbox Cognition Battery: Potential Resource for Assessing High-Functioning Spanish-Speaking Patients

Abstract Objective This study involved the preparation of high score multivariate base rates for Spanish-language NIH Toolbox Cognition Battery (NIHTB-CB) to inform neuropsychological practice with high-functioning Spanish-speaking patients. Method Participants included 250 healthy adults from NIHTB-CB normative sample (M = 38.8 ± 13.7 years-old; 72.0% women; 100% Latinx) who completed full battery (2 crystallized and 5 fluid cognition tests). Multivariate quantified frequency at which participants obtained 1+ test scores ?50th, ?63rd, ?75th, ?84th, ?91st, ?95th, ? 98th percentile based on age-adjusted demographic-adjusted normed scores, stratifications education, ability, sociocultural characteristics. Results It was common in obtain (50.8% ?84th percentile) uncommon no especially when using lower, non-conventional thresholds defining a (10.8% ?50th percentile). The obtaining varied by education (36.8% <12 years ?63rd vs. 2.1% ?16 years), ability (47.8% below average ?75th 21.9% above ability), characteristics (37.1% households national median income 6.9% above). Conclusion(s) characteristics, not fully accounted use norms. In patients higher socioeconomic status, absence is may indicate cognitive decline.
