Abstract
The present report describes a comparison of the criterion-related validity of a verbal (sentence-completion test) and of a non-verbal (pictorial) measure of self-concept. Following teacher ratings of 1,042 kindergarten children, high and low self-concept criterion groups were established (25 highest boys and girls and 25 lowest boys and girls). Each child was administered the Quantified Self-concept Inventory (Wattenberg & Clifford, 1962) and a new non-verbal test. Congruence was noted between teachers' ratings of kindergarten children's self-concepts and as assessed by a non-verbal instrument, the U-scale. Verbal devices such as sentence-completion tests have little validity at the kindergarten level.
