SELF-RATING AND FAMILY-RATING OF ADAPTIVE-BEHAVIOR AFTER TRAUMATIC BRAIN INJURY - PSYCHOMETRIC SCORES AND FRONTALLY GENERATED ERPS

Reported hem are self- and family ratings on five scales reflecting pl anning, initiation, attention/memory, arousal/inhibition, and social m onitoring among survivors of traumatic brain injury (TBI). The conting ent negative variation, a frontally generated electrophysiological res ponse elicited during a simple attentional task, was strongly predicti ve of planning and initiation as described in everyday life. Most trad itional psychometric measures were relatively poor predictors of adapt ive behavior ratings. Results are consistent with hypothesized dissoci ations in executive functions and they support the growing appreciatio n that self- and family reports of adaptation in everyday life are ess ential in evaluating the behavioral sequelae of TBI.
