Due to several previous replications of increased internal consistency reliability associated with increases in the number of alternatives per choice point, alternate forms test-retest reliability of self-ratings on a noncognitive scale was studied. Increased stability reliability associated with increases in the number of alternatives per choice point is discussed in terms of past research, theory and practical concerns.
