The Effects of Different End Anchors on Satiety Scales

Abstract

Two scales that measure hunger and fullness were compared in this study, the Satiety Labeled Intensity Magnitude (SLIM) scale and the General Labeled Magnitude Scale (GLMS). The scales differed in terms used to define satiety and their end points. The research looked at which scale was more effective and the effect of varying end anchors. To determine which scale was best, 40 volunteers came in three times and ate three snacks differing in caloric value. Each volunteer rated their hunger and fullness before and after each snack. Twenty volunteers used the SLIM scale and the other twenty used the GLMS. Analysis shows one scale was not superior to another, but the end anchors did affect how hunger and fullness were rated. The GLMS gave much more condensed data, and overall fullness was more affected than hunger.
