title: Behavioral Dyscontrol Scale deficits among traumatic brain injury patients, part I: Validation with nongeriatric patients.
abstract: The Behavioral Dyscontrol Scale is a measure of executive abilities initially designed to predict functional independence in geriatric populations. The current study examined the utility of two Behavioral Dyscontrol Scale (BDS) scoring systems in a nongeriatric sample. The BDS was administered to 49 TBI patients undergoing inpatient and outpatient rehabilitation. The results demonstrate slightly greater utility of the BDS-II scoring system, and support clinical utility of the instrument with nongeriatric patients. Specifically, the Motor Programming Factor and Environmental Independence Factor were more impaired among patients with severe, as compared to mild to moderate, TBIs. In contrast, the Fluid Intelligence Factor was more impaired among patients with frontal, as compared to nonfrontal, injuries. However, when patients were categorized by severity, lesion location differences on the BDS total score and factors were found only for patients with mild to moderate injuries. Similarly, when patients were categorized by lesion location, severity effects were only present among the nonfrontal group. Receiver Operating Characteristic curves demonstrated sensitivity and specificity rates that ranged from 60% to 100% for clinically meaningful cutting scores.
