Abstract
To examine whether a behavioural measure of frontal lobe functioning, the Brock Adaptive Functioning Questionnaire (BAFQ), could predict employment status following traumatic brain injury (TBI).A discriminant function analysis was conducted to determine the ability of the BAFQ, along with other factors, to predict occupational status post-injury.Sixty-one TBI survivors completed a background information questionnaire, the BAFQ, and an employment status rating scale.A factor analysis of the BAFQ sub-scales revealed two factors, one related to functioning in the orbitofrontal area, and one related to dorsolateral frontal lobe functioning. These two factors, along with background information, were entered into a discriminant function analysis, revealing a 77.4% accuracy rate in predicting occupational status post-injury.Demographic variables were found to differentiate employed from unemployed survivors. The BAFQ appeared useful in differentiating survivors who may return to their pre-injury employment level from those who may require modified employment.
