Validity and Reliability: The Roodt Report

1. Introduction

"The Discus personality profiler is a completely computerised assessment tool, designed to describe the different roles a person fulfils in the work environment."

(Axiom 1994:1)

The word 'personality' has been debated for centuries. Everybody has their own idea about exactly what it means. In Discus terms a personality is defined as the sum of all a person's varying response styles to varying stimuli (Swanepoel 1995:1). In practical terms, however, it is impossible to measure and evaluate every one of a person's possible responses to every possible stimulus.
