  1. Neuropsychological Testing and Functional Outcome for Individuals with Traumatic Brain Injury By Brian J. Leahy and Chow S. Lam

  2. Presented by: • James Reid • Elizabeth Hughes • Artesia McDaniel • Mike Farrell

  3. Traumatic Brain Injury as Measured by Performance on Neuropsychological Tests and Independent Living • Recent advances in medical technology has lead to significant growth in traumatic brain rehabilitation. • Plan rehabilitation according to available resources. • Increases in employment and communication skills is a high priority for patients.

  4. Cont. • Family dynamics change as the injured person becomes a dependent on the rest of the family. • Injury factors (coma, age) are associated with future employability. • Correlations showed a significance in the tests given.

  5. Participants • Adults admitted to a Midwestern brain injury rehab facility between 1991-1996 • Completed the standard administration of the neuropsychological assessment instruments involved in the study • Subjects were available to be reached for a collection of follow up data one year to six months after discharge

  6. Measures • Wechsler Adult Intelligence Scale-Revised(WAIS-R) • Comprehensive memory assessment instrument • Comprised of 8 subtests with five scores • Wechsler Memory Scale(WMS-R) • Used to evaluate patients memory

  7. Measures • Stroop Color and Word Test • Consists of three separate tasks • The task yields four scores • Four scores: attention/concentration, verbal memory, general memory and relayed recall

  8. Procedure • Neuropsychological assessment test scores from initial admittance • 6-12mo. after discharge data collected from the patients to determine levels of assistance • Current employment status and position

  9. Results • 3 sets of Dependent Variables: -Overall intellectual functioning (WAIS- R). -Memory (WMS-R) -Attentional Concentration (Stroop Color and Word Test)

  10. Results cont. • Level of assistance received showed significant difference in overall intellectual functioning. • p>.001, for employment status and overall intellectual functioning • Memory and attentional concentration showed no significant difference b/w employment and level of assistance groups.

  11. Results Cont. • Levels of assistance groups and employment groups scored significantly different on Stroop Color and Word Test.

  12. Discussion • The use of neuropsychological test in predicting long-term outcome? • No significant difference between employment or level of assistance groups found. • Stroop Color and Word Test yield sig. - but both test described as elemental in function.

  13. Discussion Cont. • Generalizibility of sample? Is sample representative of general population. -sample obtained from rehab. facility only! -90% of sample Caucasian -83% male

  14. Critical Review • Future research should refine the prediction models and continue developing interventions in rehabilitation settings to maximize functional outcome. • Explore alternate sampling methods to include patients in which rehabilitation facilities are not a viable option. • Obtain a representative sample
