title: Spanish and English Neuropsychological Assessment Scales (SENAS): further development and psychometric characteristics.
abstract: The Spanish and English Neuropsychological Assessment Scales were devised to be a broad set of psychometrically matched measures with equivalent Spanish and English versions. Study 1 in this report used item response theory methods to refine scales. Results strongly supported psychometric matching across English and Spanish versions and, for most scales, within English and Spanish versions. Study 2 supported in both English and Spanish subsamples the 6-domain model of ability that guided scale construction. Study 3 examined differential item functioning (DIF) of one scale (Object Naming) in relation to education, ethnicity, gender, and age. Effects of DIF on scale-level ability scores were limited. Results demonstrate an empirically guided psychometric approach to test construction for multiethnic and multilingual test applications.
