Executive functioning influences a host of other cognitive processes and people who attend neuropsychological services are more likely to display executive dysfunction than any other cognitive deficit (Stuss & Levine, 2002). Impairment in executive functioning disrupts a person's ability to effectively employ their intact areas of functioning, and undermines effective self-management of other areas of dysfunction, hampering attempts to employ compensatory strategies. Therefore, assessment of a person's executive functioning is a high priority as part of a comprehensive neurorehabilitation plan. Guided by the International Classification of Functioning, Disability, and Health model (ICF model; Peterson, 2005), we suggest that an important development in the field is moving to formal assessment of executive performance in functional contexts, in addition to more traditional assessment of executive impairment. We outline a number of existing studies in this area, review current measures that can provide clinicians with useful information on these issues, and discuss how this research could be further advanced.

In this initial trial of a novel assessment method, adequate inter-rater reliability was found. The measure was associated with standard neuropsychological measures, and our healthy control group performed better than the TBI group. The measure appears to be an ecologically valid measure of executive functioning.
