Dependability of Anchoring Labels of Likert-Type Scales.
This study uses generalizability theory to examine the dependability of anchoring labels of Likert-type scales. Variance components associated with labeling were estimated in two samples using a two-facet random effect generalizability-study design. In one sample, 173 graduate students in education were administered 7 items measuring attitudes toward quantitative methodology. The other sample consisted of 108 graduate students in education who responded to the 8-item Life Orientation Test (M. F. Scheier and C. S. Carver, 1985). From both samples, variance components associated with labeling were found to be trivial, contributing little to the observed score variance. The dependability of anchoring labels was maintained for both normative and absolute interpretations of individual differences with respect to what was being measured. Two plausible explanations were provided. Respondents could primarily be using the numerical information in rating a Likert-type scale or could treat both the scale numerals and verbal labels as representing ordinal rather than equidistant relations.
