Development of the Overt-Covert Aggression Inventory

Abstract

The expression of anger in Japanese people is different from that of other races. We developed a new brief inventory, the Overt-Covert Aggression Inventory, to assess aggressive behavior of Japanese people by focusing on their uniqueness and examined us reliability and validity. This inventory, the Center for Epidemiological Studies Depression scale, the Japanese version of the Buss-Perry Aggression Questionnaire, and the Picture-Frustration Study were administered to 3,104 men and 316 women in a factory. Internal consistency, test-retest reliability, concurrent validity, and construct validity of the scale were examined. We confirmed that the Overt-Covert Aggression Inventory has adequate reliability and sufficient concurrent validity; however, further studies of the construct validity and discriminant validity are required.
