Specificity rates for non-clinical, bilingual, Mexican Americans with California Verbal Learning Test3, verbal fluency, and Rey 15-IR performance validity measures

Abstract Objective: To measure failure rates among non-clinical, Mexican American, bilinguals on embedded performance validity measures from the California Verbal Learning Test3 and verbal fluency and the stand-alone Rey 15-item test plus recognition (Rey 15-IR) using valid/invalid performance cut scores developed for monolingual, English-speakers. Method: Participants were 60 consecutive recruits, aged between 18 and 75 years, with ≤16 years of education who self-identified as bilingual (confirmed via formal assessment) and chose the language of assessment, Spanish or English, for the performance validity tests. Results: The only performance validity measure studied with a higher failure rate (19%) than that for monolingual, English-speakers (9%) was semantic fluency administered in Spanish. Conclusions: Valid/invalid performance cut scores derived for monolingual English-speakers generated comparable or lower failure rates among Mexican American bilinguals on CVLT3 forced-choice recognition, CVLT3 yes–no recognition hits, letter fluency, semantic fluency in English, and the Rey 15-IR.
