A brief overview of the Patient Competency Rating Scale: updates and additions to the COMBI.

A the physiologically based unawareness of one’s deficits due to disability, is common after head injury.1 Individuals with brain injury also often overand underestimate their abilities secondary to a lack of insight.2 Lack of awareness and insight can often negatively impact rehabilitation participation and outcomes and should be assessed and monitored. The Patient Competency Rating Scale (PCRS) is a 30-item self-report measure developed in 1986 by Prigatano and colleagues3 to evaluate lack of insight. The scale was designed for use in a post–acute setting to determine awareness of deficits after traumatic brain injury (TBI), by measuring patients’ ability to carry out cognitive, self-care, and social tasks.
