Abstract

The purpose of this study was to collect normative data and test for the reliability of a new strategy index, quantified using a computer-assisted algorithm on the Five-Point Test (FPT), developed by Regard, Strauss, and Knapp (1982). Additionally, the study was aimed at investigating the influence of the new index on the total number of designs and preservative errors. Participants included one hundred and fourteen individuals from Cleveland State University and the community for time one, and sixty two individuals for time two. Participants were administered the Five Point Test and the Delis-Kaplan Design Fluency Test developed by Delis, Kaplan & Kramer (2001) across two time periods approximately two months apart. Total designs and perseveration errors were recorded for both tests. The new index consists of three types of strategy: rotation, addition, and deletion and was quantified using a computer-assisted algorithm developed by Dr. Amir Poreh. The results of this study show a test-retest correlation of (r = .755, p=.000) for the new strategy index across two administration periods, and an overall higher reliability for the Five Point Test in comparison to the Delis-Kaplan Design Fluency Test . Furthermore, the study using a stepwise regression analysis showed the new strategy index significantly predicted the number of total designs (F = 38.39, p=.000), and significantly predicted the number of perseveration errors (F = 16.33,p=.000)
