A-109 Examining Relationship of Brain Injury, Anxiety and Workload on Trail Making Test Performances

Abstract Objective Both anxiety and traumatic brain injury (TBI) are both related to poorer Trail Making Test (TMT) performances. TBI survivors exhibit a greater incidence of in contrast the general population. We evaluated relationship between on TMT perceived workload ratings. Method The sample consisted 39 moderate-to-severe [(21 with normal symptoms (NSA) 18 abnormal (ASA)] 51 healthy comparison (HC; 26 NSA 25 ASA) participants. Results ANCOVA’s, controlling for age, revealed HC group outperformed part A B (TMT-B). An interaction emerged TMT-B, TBI-ASA participants TBI-NSA HC-NSA their counterparts ASA. Ratings physical demand frustration were reported higher compared Moreover, had interactive effects NASA-TLX temporal ratings, scores TBI-NSA. Lastly, an ASA reporting better performances HC-NSA. Conclusions As expected, did worse tasks. Next, we found that impacted TMT-B performance (i.e., frustration, demand) more than In future, studies larger size should examine if influences person mild TBI.
