| Abstract: | This study tested three scoring keys for the MTAI—the published empirical key (E); a logical key with three different weights, i.e., + 1, 0, -1; and a new logical key with five different scoring weights, one for each of the five responses in MTAI items, i.e., +2, +1, 0, -1, -2. The latter, termed the pentachotomous-logical (P-L), provided scores with slightly higher internal consistency and a frequency distribution which is not so significantly skewed as the others and which provides greater spread among extreme positive and negative scores. Use of the P-L scoring weights would facilitate the psychological interpretation of the MTAI. However, conclusion that the P-L scoring key is an improvement must be tempered by the fact that an expected increase in construct validity was not found. |
