Estimates of validity and reliability for the hemispheric mode indicator.
Concurrent validity of scores of the Hemispheric Mode Indicator (a measure of cognitive hemispheric dominance) was assessed by product-moment correlation with scores for the Human Information Processing Survey (a more-studied measure of hemispheric dominance) for 27 nurse-anesthetist students and 94 medical students (r = .61 and .69, respectively). For 70 of the medical students, test-retest stability was only fair (r = .74). For 525 undergraduates and 156 medical students, although alpha coefficients were .78 and .84, respectively, consideration of interitem correlations and principal components analyses indicated that some of the Hemispheric Mode Indicator's items are unsuitable as worded and that the 32 items probably represent more than one underlying latent variable.
