Abstract
The use of the standard deviation of item ratings as a criterion of scale anchor selection is criticized on several grounds. Data are presented which show that the criterion (a) lacks verification, (b) leads to mid-range scale gaps, and (c) wastes large numbers of potentially useful items. An alternative criterion that is based on item intercorrelation procedures is suggested and tested. Results indicate that the alternative criterion does not lead to the negative outcomes of the SD criterion. Discussion indicates that the alternative criterion is more theoretically meaningful than the SD criterion.
