Adequate effort by examinees during neurocognitive testing is a prerequisite to valid interpretation of test results. Utilizing performance validity tests (PVTs) is strongly recommended within pediatric mild Traumatic Brain Injury (mTBI) populations. PVTs have historically been created based on majority-white and monolingual groups; investigating their validity in additional patient populations remains essential. The Automatized Sequencing Task (AST) was developed as a brief validity measure within mTBI youth (Kirkwood, et.al., 2014). This study aimed to examine the clinical utility of the AST among youth identifying as Hispanic/Latino and/or bilingual within a mTBI clinical sample.
Participants ages 8-17 (N=103, M age=14.08, SD=2.2, 51.5% male, 42.7% Hispanic/Latino, 23.6% bilingual) were drawn from an outpatient mTBI/concussion program within the past 2.6 years. Median time of evaluation since injury was 3.7 weeks. Eligibility criteria included: 1) evaluated for a mTBI (GCS . 13) and 2) 8 through 17 years of age. Language status included English only and English-Spanish bilingual youth. Of the bilingual youth, 95% were considered English dominant. Youth were timed while reciting four well-learned (i.e., automatized) sequences as rapidly as possible: 1) the alphabet, 2) counting from 1-20, 3) the days of the week, and 4) the months of the year. Pass rates for the AST were examined using chi-square tests to compare performance based on ethnic/cultural identity (Hispanic vs Non-Hispanic), language status, age (children 8-12; teens 13-17), and gender.
In the clinical sample, 11.7% (n=12) could not complete AST months; 75% of non-completers were Hispanic/Latino. Participants who identified as Hispanic/Latino compared to Non-Hispanic/Latino participants were significantly more likely to fail the 4-item AST, χ2(1) =4.3, p<.05. The odds of failing the 4-item AST was 2.3 times higher if patients identified as Hispanic/Latino. Further, patients identifying as bilingual were even more likely to fail the 4-item AST, χ2(1) =4.5, p<.05. The odds of failing the 4-item AST was 3.0 times higher if patients were bilingual. There were no ethnicity or bilingual group differences in AST failure when examining performance on the 3-item AST. Neither age nor gender were a significant predictor of failure on the 3-item or 4-item AST.
Results suggest that the month item on the AST does not function consistently across Hispanic/Latino and bilingual youth. It cannot be presumed to be ‘automatic’ as a significant number of Hispanic/Latino and/or bilingual patients were unable to complete the month item, but with otherwise intact performance on the first three items. Administering only the first three items on the AST appears to be a more culturally sensitive alternative given the increased odds of 4-item failure in Hispanic/Latino and bilingual youth. Additional research is needed to explore the predictive validity of the AST as a PVT in varying ethnic, culturally, linguistically, and socioeconomically diverse mTBI pediatric populations.
