KW - Task Performance and Analysis KW - Video Recording AB - This laboratory research compared the reliability, validity, and accuracy of a computerized adaptive rating scale (CARS) format and 2 relatively common and representative rating formats. The CARS is a paired-comparison rating task that uses adaptive testing principles to present pairs of scaled behavioral statements to the rater to iteratively estimate a ratee's effectiveness on 3 dimensions of contextual performance. Videotaped vignettes of 6 office workers were prepared, depicting prescripted levels of contextual performance, and 112 subjects rated these vignettes using the CARS format and one or the other competing format. Results showed 23%-37% lower standard errors of measurement for the CARS format. In addition, validity was significantly higher for the CARS format (d = .18), and Cronbach's accuracy coefficients showed significantly higher accuracy, with a median effect size of .08. The discussion focuses on possible reasons for the results.

Specifically, the reliability, validity and accuracy of the performance ratings from each for mat were examined. One hundred twelve participants viewed six 5-minute videotape s of office situations and rated the performance of a target person in each vide otape on three contextual performance dimensions-Personal Support, Organizationa l Support, and Conscientious Initiative-using CARS and either behaviorally-ancho red or graphic rating scales. Performance rating properties were measured using Shrout and Fleiss's intraclass correlation (2, 1), Borman's differential accurac y measure, and Cronbach's accuracy components as indexes of rating reliability, validity, and accuracy, respectively. Results found that performance ratings mad e using the CARS were significantly more reliable and valid than performance rat ings made using either of the other formats. Additionally, CARS yielded more acc urate performance ratings than the paper-and-pencil formats. The nature of the C ARS system (i.e., its adaptive nature and scaling methodology) and its paired co mparison judgment task are offered as possible reasons for the differences found in the psychometric properties of the performance ratings made using the variou s rating formats.
