Context: Student-athletes are commonly administered the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT®) battery at preseason baseline and post concussion. The ImPACT® is available in many different languages, but few studies have examined differences in cognitive performances and symptom ratings based on language of administration.
Objective: This study examined differences on ImPACT® neurocognitive composites and symptom reporting at preseason baseline testing between student-athletes completing ImPACT® in Spanish versus English.
Design: Cross-sectional study.
Setting: Preseason baseline testing for a high school concussion management program in STATE-XXX.
Patients of Other Participants: Adolescent student-athletes completing testing in Spanish (n=169) and English (n=169) were matched on age, gender, and health/academic history. Language groups were compared on each outcome for the full sample and for gender-stratified subsamples.
Main Outcome Measure(s): Neurocognitive composite scores and individual and total symptom severity ratings from the ImPACT® battery.
Results: Athletes tested in Spanish had lower neurocognitive performances on two of five composite scores (i.e., Visual Motor Speed, p<.001, d=.51; Reaction Time: p=.004, d=.33) and reported greater symptom severity (p<.001, r=.21). When analyses were stratified by gender, similar Visual Motor Speed differences were observed between language groups among boys (p=.001, d=.49) and girls (p=.001, d=0.49), whereas Reaction Time showed a larger group difference for boys (p=.012, d=.42) than girls (p=.128, d=.21). Language group differences in symptom reporting were similar for boys (p=.003, r=.22) and girls (p=.008, r=.21), with more frequent endorsement of physical and affective symptoms by athletes tested in Spanish.
Conclusions: Language group differences in total symptom severity were small (r=.21), and language group differences in neurocognitive performances were small-to-medium (d=.05–.51). Compared to previous studies comparing athletes tested in Spanish and English on ImPACT®, smaller effects were observed in the current study, which may be attributable to close matching on variables related to neurocognitive performances and symptom reporting.
Adolescent student-athletes completing baseline preseason ImPACT® in Spanish had lower performances on the Visual Motor Speed and Reaction Time composite scores than those tested in English.
When interpreting ImPACT®, clinicians should be mindful that some neurocognitive performances may be, on average, lower than expectation among student-athletes tested in Spanish when compared to English-language norms.
During baseline preseason assessments, student-athletes tested in Spanish reported greater symptom severity, including more physical and affective symptoms, than those tested in English.
