Self-Ratings in Attitude Measurement: Resistance to Short-Term Recalibration and ContrastGeorgia Institute of Technology
The University of Akron
The University of Akron An extension has been made of past research on the theory of "psychological perspective" (Ostrom and Upshaw, 1968) that emphasizes the concept of rating scale calibration in attitude measurement. Perspective theory may hold implications for attitude surveys in that differences in attitude across groups or individuals may be diluted, exaggerated, or real depending on differences in perspective when completing self-ratings of attitude on a graphic scale. A second implication, however, is that scales may become recalibrated transiently, as in the classic contrast effect. A conservative test of this second implication of the model was provided to investigate whether the use of simple graphic rating scales in attitude measurement may be complicated by this type of transient scale shift. Hypothesized initial shifts and their temporal decay were investigated. However, the data did not support the short term recalibration effect. Overall, the data supplemented past research that supports the use of graphic rating scales as valid and reliable measures of attitude. It is also suggested that in some situations, a single graphic rating may be effectively substituted for longer and more sophisticated scaling techniques.
