“…Individual scores were analysed and grouped as high or low self-awareness of deficits. According to previous reports, high self-awareness was considered if discrepancy between the patient's and the significant other's rating was less than 28 [10,11]. Since the structure of the PCRS allows global minimal differences with significant discrepancies on each question, we also required an identical patient's versus significant other's score on ≥15 items of the scale.…”

“…Moreover, the PCRS has been validated in Spanish speakers and preliminary cutoff scores for severity of impaired awareness have been established [10,11]. The acquisition of self-awareness has been clearly linked to neuropsychological deficits,neuropathological lesions and psychological symptoms.…”

“…Severity of injury has shown some relationships with self-awareness deficits (Prigatano, 1999b), but many other studies have not found any associations (Allen & Ruff, 1990;Anderson & Tranel, 1989;. Other studies found associations in the opposite direction to that predicted (Sawchyn et al, 2005;Sherer et al, 1998c) or mixed results depending on which measure of severity was used (GCS or PTA) (Prigatano et al, 1998). Poor performance on intelligence tests has been associated with self-awareness in TBI, with lower post-injury verbal intelligence associated with greater impaired awareness (Anderson & Tranel, 1989).…”

Recent models of impaired awareness in brain injury draw a distinction between metacognitive knowledge of difficulties and online awareness of errors (emergent and anticipatory). We examined performance of 31 Traumatic Brain Injury (TBI) participants and 31 healthy controls using a three-strand approach to assessing awareness. Metacognitive knowledge was assessed with an awareness interview and discrepancy scores on three questionnaires-Patient Competency Rating Scale, Frontal Systems Behavioral Scale and the Cognitive Failures Questionnaire. Online Emergent Awareness was assessed using an online error-monitoring task while participants performed tasks of sustained attention. Online anticipatory awareness was examined using prediction performance on two cognitive tasks. Results indicated that the TBI Low Self-Awareness (SA) group and High SA group did not differ in terms of severity, chronicity or standard neuropsychological tasks but those with Low SA were more likely to exhibit disinhibition, interpersonal problems and more difficulties in total competency. Sustained attention abilities were associated with both types of online awareness (emergent and anticipatory). There was a strong relationship between online emergent and online anticipatory awareness. Metacognitive knowledge did not correlate with the other two measures. This study highlights the necessity in adopting a multidimensional approach to assessing the multifaceted phenomenon of awareness of deficits. (JINS, 2007, 13, 38-49.)
