Abstract
With self-rating (or “Likert”) scales, reliability is partly a function of number of items and it is therefore suggested that increasing the number of measurements (items) should also improve projective test reliabilities. Empirical examples in the field of n Ach measurement are given that support this contention. Evidence is also mentioned which suggests that reliability can further be improved by different scoring systems and stimulus materials.Keywords
