Ratings are assumed to be accurate, yet they are subject to biases.

This study aimed to extend prior findings using an objective approach to identify determinants of bias in ratings.</p><p><strong>Method: </strong>Participants were 118 individuals with MCI and their informants. Three discrepancy variables were generated including the discrepancies between (1) self- and informant-rated functional status, (2) informant-rated functional status and objective cognition (in those with MCI), and (3) self-rated functional status and objective cognition.

The risk for relative underreporting of functional abilities by individuals with higher stress levels aligns with previous research.
