Criterion validity of a functional cognitive task in patients with severe traumatic brain injury.
ABSTRACT To verify criterion validity of measures from a functional cognitive task (FCT) carried out with patients with severe traumatic brain injury (sTBI) at 2-5 years post-injury.
Forty-six patients with sTBI took part in a long-term outcome study where the FCT and the Neurobehavioural Rating Scale-Revised (NBRS-R) were administered and the FIM™ instrument was rated. The FCT is a telephone information gathering task for evaluating functional cognitive skills.
Ten of 16 measures of the FCT were significantly correlated with similar or related concepts from the NBRS-R. The FIM™ cognitive score and the individual items of this score were significantly correlated with 13 of the FCT measures and with the percentage of amount of information gathered. Internal consistency was good for 13 of 16 measures. Overall, patients generally had mild difficulty on the FCT concepts.
The FCT can be used with patients with sTBI to evaluate certain aspects of functional cognition. It has good criterion validity and internal consistency, but additional research is required to further measure reliability and its applicability to other severity of TBI and to other phases of recovery.

ABSTRACT: To obtain a comprehensive understanding of long-term outcome after severe traumatic brain injury (sTBI). Forty-six patients with sTBI. Comparison of interdisciplinary evaluation results at discharge from acute care and at 2 to 5 year follow-up. Extended Glasgow Outcome Scale, the FIM instrument, and the Neurobehavioral Rating Scale-Revised. Significant improvement was observed on the FIM instrument, the Extended Glasgow Outcome Scale, and on 3 factors of the Neurobehavioral Rating Scale-Revised. These measures at discharge were significant predictors of outcome. Patients with sTBI 2 to 5 years postinjury showed relatively good physical and functional outcome but poorer cognitive and emotional outcome.The Journal of head trauma rehabilitation 01/2008; 23(5):294-303. · 2.39 Impact Factor

ABSTRACT: The goal of this study was to measure the very long-term mental and psychosocial outcomes of severe traumatic brain injury (TBI). Seventy-six persons with severe TBI were evaluated extensively by means of standardized scales, neuropsychological tests and evaluations by family members, at an average of 14.1 (SD = 5.5) years post-injury. Six mental and functional domains were examined: psychiatric symptomatology, cognitive abilities, vocational status, family integration, social functioning, and independence in daily routines. The findings indicate a long-term differential effect of severe TBI, with seriously affected psychiatric symptomatology, family and social domains, as compared to moderately influenced cognitive, vocational and independent functioning. Relatively high rates of depression, psychomotor slowness, loneliness and family members' sense of burden were found. In addition to their epidemiological importance, the results indicate that persons with TBI and their families may need professional assistance to maintain a reasonable psychosocial quality of life, even more than a decade post-injury.Brain Injury 04/2001; 15(3):189-209. · 1.51 Impact Factor

ABSTRACT: A quantitative investigation of the ability to carry out a variety of cognitive tasks was performed in 3 patients who had sustained traumatic injuries which involved prefrontal structures. All 3 had severe difficulties in 2 tests which required them to carry out a number of fairly simple but open-ended tasks over a 15-30 min period. They typically spent too long on individual tasks. All patients scored well on tests of perception, language and intelligence and 2 performed well on a variety of other tests of frontal lobe function. Explanations for their difficulty on the multiple subgoal tasks in terms of memory or motivational problems could be excluded. It is argued that the problem arose from an inability to reactivate after a delay previously-generated intentions when they are not directly signalled by the stimulus situation.Brain 05/1991; 114 ( Pt 2):727-41. · 9.92 Impact Factor
