The Occupational Performance Assessment–Response Distortion (OPerA-RD) Scale

Abstract

Abstract. The ubiquity and consequences of job performance evaluations necessitate accurate responding. This paper describes two studies designed to develop (Study 1) and provide initial validation (Study 2) for a new measure specifically designed to assist in this context: the Occupational Performance Assessment–Response Distortion (OPerA-RD) scale. This 20-item scale is contextualized to the workplace and was developed by identifying items that could detect over- and under-reporting of job performance by self- or other-report in four independent faking samples. Initial validation of the OPerA-RD was supported by expected differences between within-group faking and control conditions in subsequent samples, specifically over- and under-reporting of job performance by self- or other-reports. Implications for research and applied settings are discussed.
