| dc.description.abstract | This study examines the validity of using a combination of two psychometric measures, an emotional adjustment measure, and functional assessment measures to predict vocational outcome in a traumatically brain injured population. Patients included 33 males and 11 females, with an average age of 32.3 years, and a stable work history over the past three years prior to injury. All had sustained a traumatic brain injury in the 12 months prior to initial testing, with a mean of 3.8 months since injury. Levels of severity of injury included 24 patients with severe injury, 12 patients with moderate injury, and 8 patients with mild injury. Patients completed the Logical Memory subtest (LM) of the Wechsler Memory Scale-Revised, Paced Auditory Serial Addition Test (PASAT), Beck Depression Inventory (BDI), and Personal Capacities Questionnaire (PCQ). A clinician working closely with the patient also completed the Functional Assessment Inventory (FAI) and the Behavior Checklist (BC) at the time of initial testing. Follow-up testing on available patients (n=16) was completed approximately six months after initial testing. Comparison of the functional assessment measures demonstrated that patients exhibited a decreased awareness of functional limitations relative to clinician's ratings, but identified an increased number of personal strengths. The present study demonstrates the first comparison of FAI and PCQ ratings in a TBI population, as well as the first available field research using the PCQ. Results also indicated that the only significant predictor on earned income after six months was the overall functional limitations score on the PCQ. The only significant difference in patients' test performance at six months with scores at initial testing was seen on the PASAT, which suggested that patients had a significant improvement in their speed of information processing after six months. In addition, comparison of patients from Canadian and American rehabilitation agencies, respectively, revealed no significant differences between patients at either initial testing or at follow-up. | en_US |
