Background Patient Competency Rating Scale (PCRS-R-BR) is a clinical tool to evaluate the degree of competence in cognitive skills perceived by patients with brain injuries. However, no studies have investigated the influence of sociodemographic variables on self-report and self-awareness of healthy individuals. Aim This study aimed to (1) present normative data from the PCRS-R-BR in a healthy adult Brazilian sample; and (2) investigate psychometric properties of the scale Method One hundred and fifty-four adults that were divided in three age groups and two education groups and their informants completed the PCRS-R-BR. Results Score on the PCRS-R-BR Patient's Form differed as a function of age with younger adults reporting less competency than older individuals. An education effect was found on Attention/Working memory Factor on the Informant's PCRS-R-BR with informants of higher education adults reporting better competency than lower education individuals. A gender effect was observed on the Informant's Form. The Informant's Form scores of informants of women were higher than the scores provided by the informants of men. PCRS-R-BR showed adequate consistency coefficients and six factors. Conclusion PCRS-R-BR scores showed acceptable validity evidence and provides information regarding how age and gender effects may influence ratings in a Brazilian sample. [ABSTRACT FROM AUTHOR]
