Twenty-two students in the Coastline Community College Traumatic Head Injury Program completed two sessions of neuropsychological testing spaced 2-3 months apart, using ANAM V1.0. Eight (GP1) were marginally injured, seven (GP2) mildly, and seven (GP3) moderately. Comparisons of first-session accuracy scores with normative data revealed that GP1 was impaired on one test, while GPs 2 and 3 were impaired on 3 and 4 tests, respectively. Second-session accuracy scores were normal for GPs 1 and 2 on all tests, and impaired on one for GP3. Comparisons of first-session efficiency scores with normative data indicated that GP1 was significantly impaired on 2 tests, while GPs 2 and 3 were impaired on all 6. Second-session efficiency scores were normal for GP1 on 5 tests; GPs 2 and 3 also improved but remained impaired on all 6 tests. Based on efficiency, 91 % of the individuals were correctly classified.
