The Washington University Sentence Completion Test compared with other measures of adult ego development.

Abstract

One hundred seven men who had been studied prospectively from age 18 to age 63 completed the Washington University Sentence Completion Test at age 55 +/- 2 years. Ego level as assessed by the Sentence Completion Test correlated significantly with psychosocial maturity, with number of psychiatric visits, and, perhaps, with creativity. Ego level as assessed by the Sentence Completion Test did not correlate with mental health, psychopathology, or maturity of defenses. The authors discuss possible reasons for these findings.
