Abstract Objective The Dot Counting Test (DCT) is a performance validity test. McCaul et al. (2018) recently revised the DCT cut-off score from ≥17 to 13.80; we evaluated the new cut-off in non-Latinx Caucasian and Caucasian Latinx traumatic brain injury (TBI) survivors and healthy comparison (HC) participants. Method The sample consisted of 37 acute TBI (ATBI; 11 Caucasian Latinx; 26 non-Latinx Caucasian), 27 chronic TBI (CTBI; 10 Caucasian Latinx; 17 non-Latinx Caucasian), and 55 HC (29 Caucasian Latinx; 26 non-Latinx Caucasian) participants. Results An ANCOVA, controlling for age, revealed no DCT E-scores differences between groups. Both the conventional and the new cut-off scores had different failure rates in ATBI (conventional cut-off: 0%; PNC: 16%), CTBI (conventional cut-off: 7%; PNC: 15%), and HC (conventional cut-off: 10%; PNC: 11%) participants. For the Caucasian Latinx group (conventional cut-off: 6%; PNC: 12%) and the non-Latinx Caucasian group (conventional cut-off: 6%; PNC: 14%), demonstrated different failure rates across cut-off scores. Group differences were found with the McCaul et al. (2018) cut-off and the conventional cut-off. Also, chi-squared analysis revealed non-Latinx Caucasian participants with ATBI had greater failure rates than Caucasian Latinx participants with ATBI. Conclusion The new DCT cut-off score resulted in greater failure rates in TBI survivors. Also, this effect appears to be most pronounced in non-Latinx Caucasian persons with ATBI. Future work should investigate possible reasons for these differences so that more stringent DCT can be utilized in a way that provides less biased results for brain injury survivors across racial and ethnic groups.
