Structured Rating Scales.
Linacre, John Michael
A rating scale can be expressed as a chain of dichotomous items. The relationship between the dichotomies depends on the manner in which the rating scale is presented to the test taker. Three models for ordered scales are discussed. In the success model, which represents growth, the lowest or easiest category is presented first. If the test taker succeeds, consecutively higher, more difficult categories are presented until the test taker finally fails or all categories have been presented. In the failure model, which represents mastery, the highest and most difficult category is presented first. If the test taker fails, consecutively lower and easier categories are presented until the test taker finally succeeds or all categories have been presented. In the D. Andrich model, which represents attitude and other closed rating scales, all categories are presented simultaneously and the test taker selects the one most germane. One table and four graphs are included. (Author/SLD)
