Studies in projective techniques: I. The reliability of a multiple choice group Rorschach test

Abstract

Using the split-half technique, analysis of 655 college students' scores on a modified form of the Harrower-Erickson Multiple Choice (Group Rorschach) Test yielded reliability coefficients of .61 for first choice, and .40 for alternate choice scores. After further analysis several scoring revisions were tested on a group of 131 subjects. Results indicate weaknesses in the standard scoring procedure. There is a need of separate male and female scoring keys, a revision of classification items, and an increase in the number of inkblots. A lack of strongly discriminative items was shown, and the intelligence factor added little to score variabilities. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
