Personality assessment often uses information obtained from knowledgeable informants, but data derived from informant report measures are not entirely objective. This begs the question, what factors contribute to evaluative bias on informant report measures of personality? One factor that might bias informant ratings is the informant’s subjective state of well-being. Since informant-ratings are based on the informant’s perception of the individual being rated, scores can be contaminated by information-processing heuristics that allow extraneous factors (e.g., current state of well-being) to influence the informant’s evaluation of the client. Accordingly, the proposed study explored associations between informants’ subjective well-being and evaluative bias on informant report measures of personality using a Social Relations Model approach. Per the Social Relations Model approach, participants joined the study in groups of five or more and completed the study via round-robin design. It was hypothesized that the amount of variance found on informant report measures attributable to perceiver effects would be inversely correlated with informant’s subjective well-being. Results revealed environmental well-being to be significantly associated with evaluative bias in informant ratings of antagonism, with other associations trending toward significance. The clearer understanding of these interactions has the potential to facilitate improved personality assessment in research and clinical practice.
