Reliability and Validity of the Paragraph Completion Test: Theoretical and Empirical Notes

Abstract

The Paragraph Completion Test has become the most widely used measure of the integrative component of conceptual complexity: namely, the ability to think in multi-conceptual terms about given stimulus domains. The test has consistently predicted complex behavioral performance in experimental settings and correlates positively with theoretically related measures of personality and cognition. Inter-rater, split-half, and preliminary test-retest reliability coefficients are also satisfactory, making the test a psychometrically sound and valid measure of complexity.
