Aggression-Altruism: A Scale and Some Data on Its Reliability and Validity

This article reports on the development of a scale designed to measure aggression. Using usual procedures for Thurstone scaling, a thirty-seven item Aggression Scale was created, Form A consisting of twenty items and Form B of seventeen. The test-retest reliability coefficient was .60. Results from three validity studies showed that aggression as measured by the Aggression Scale was related to perceived mild aggression training by fathers for males only, to nationalism, and to Machiavellianism.
