BACKGROUND: Anosognosia is a lack of awareness of personal deficits that is
commonly observed in people with an acquired brain injury (TBI).
OBJECTIVE: The purpose of this paper is to examine whether self-appraisal of
executive functioning differs for students with and without TBI.
METHODS: Students who had survived a TBI and those who had never had a TBI filled
out the Behavior Rating Inventory of Executive Functioning from three different
perspectives. Each participant was paired with an observer who was familiar with
the person's behavior. Self-appraisal ratings, observer ratings of the
participant, and reflective appraisal of how the participant thought the observer
would rate them were compared.
RESULTS: For the students without TBI, reflective appraisal was significantly
correlated with self-appraisal but observer appraisal was not. For students with
TBI, neither reflected appraisal nor observer appraisal correlated with
self-appraisal. Both TBI and non-TBI participants overestimated their problems on
measures of Inhibition, Shifting, Emotional Control, Initiation, and
Planning/Organizing. TBI participants underestimated their problems on measures
of Working Memory, Organization, and Task Monitoring relative to the non-TBI
group.
CONCLUSIONS: Students with TBI do not accurately perceive how others perceive
their behavior.
