Reliability and Stability of the Comrey Personality Scales

Abstract
Split-half and retest reliabilities were computed on Comrey Personality Scales administered to 153 Navy Hospital Corpsmen on two occasions separated by about 5 mo. Corrected split-half reliabilities for the 8 personality trait scales were between .66 and .94, with an average of .87, on the first administration and between .68 and .94, with an average of .85, on the second administration. Retest reliabilities for these eight scales were between .59 and .74, with an average of .66. t tests comparing scale means for each administration yielded significant differences on seven of the eight personality trait scales, the Validity Check scale, and the Response Bias scale. On all of these scales, except the Validity Check, the first administration means were higher than the second administration means.
