Effects of modified instructions on the Washington University Sentence Completion Test of Ego Development.

This research project was designed to investigate the possibility that asking subjects to respond in a mature manner when they take the Washington University Sentence Completion Test of Ego Development (WUSCTED) would result in higher test scores and improve the test-retest reliability of the measure. The results showed that there was a significant increase in Total Protocol Ratings (TPRs) and item sums in the experimental group (n = 32) over the control group (n = 32). In addition, the experimental group spent more time and used significantly more words in its response than did the control group. The question of improved test-retest reliability remains only tentatively resolved. The item sum scores showed a significantly higher correlation for the experimental instruction than for the control, although the test-retest agreement between TPR levels was insignificantly different in the two instructional groups.
