Alternative measures of cognitive complexity as predictors of communication performance

Abstract

Abstract Two studies were conducted to compare the predictive validity of the two of the most popular measures of cognitive complexity: Bieri et al.'s (1966) grid-based measure (elicited and provided versions) and Crockett's (1965) Role Category Questionnaire (RCQ). Two other grid-based measures of construct system quality also were included. Criterion measures included indices of the accommodative, person-centered quality of communication behavior and social reasoning in a variety of contexts. Results of both studies consistently show Crockett's measure to be a significant predictor of all criterion measures. Bieri et al.'s measures were generally unrelated, although the elicited construct version performed best as a predictor. The two measures of complexity were essentially unrelated in both studies. Implications of the findings for future use of the RCQ and grid-based measures of complexity are discussed. For those interested in the relation of constructs and communication behavior, the RCQ is recommended.
