Reliability Estimates for Total,Factor,and Group Mean Scores on the Khatena-Torrance Creative Perception Inventory

Abstract

Responses of 31 samples of adults (N = 2503) and 37 samples of children (N = 7048) to the two parts of the Khatena-Torrance Creative Perception Inventory were used to estimate internal consistency reliabilities for total scales and factor scores and to estimate the reliability of group means. The information may be helpful to users of Something About Myself and What Kind of Person Are You? when deciding what typical reliabilities to expect or in planning studies involving the measures. The analyses suggest (a) only total scores for the inventories may approach acceptable reliability for making decisions about individuals, (b) factor scores tend to be less reliable so they may only be acceptable for making decisions about groups, and (c) reliabilities of group means for total scores are acceptable for groups of about 40 adults or 65 children.
