Comparison of Two Non-Intellective Scales of Intelligence and Their Relationship to Intellectual Changes following Surgery

Abstract

Two MMPI scales of intelligence measuring intellectual efficiency (Ie and Iq) were significantly correlated with WAIS IQ, Wechsler Memory Scale memory, and Bender-Gestalt errors for a sample of 102 patients undergoing coronary artery surgery (rs = .54 to .36). Pre-operative intellectual efficiency was not predictive of changes in intelligence, memory, and perceptual-motor ability assessed six days post-operatively. The intellectual efficiency scales were also positively correlated with adjustment as measured by MMPI basic scales and Dependency (Dy), Ego Strength (Es) and Manifest Anxiety (At) scales.
