“…O'Keefe and Sypher (1981) compared reliability and validity data for many different measures of cognitive complexity, including those based on Kelly's repertory grid, and concluded that “only Crockett's RCQ measure appears to satisfy all the criteria for an adequate complexity measure” (p. 85). Several studies (for example, Burleson, Applegate, & Neuwirth, 1981; Burleson, Waltman, & Samter, 1987) have found little relationship between RCQ assessments of cognitive complexity and independent measures of loquacity, verbal fluency, and verbal intelligence. The RCQ has been found to have test‐retest reliability of .95 over 4 months for an eight‐role version (Crockett, 1965), and .84–.86 over a 4‐week period for the standard two‐role version (O'Keefe, Shepherd, & Streeter, 1982).…”
