Will Bootstrap Clustering Resuscitate Repertory Grid Assessment of Cognitive Complexity? Convergence with Integrative and Dialogical Complexity Suggests It Could

Abstract

This article is concerned with an introduction and examination of a new cognitive complexity index derived from repertory grid data. Our approach follows Heckmann's and Bell’s introduction of bootstrap clustering of grid data. In order to examine the validity of the new index, we reanalyze data from an older study. The reanalysis showed that the new index correlated significantly with other independent complexity indices: integrative complexity and dialogical complexity. The directions of correlations were in accordance with complexity theories that underlie the indices. These findings support the validity of the cognitive complexity index based on bootstrap clustering.
