Abstract
It has been noted that aggression is one of the risk factors of physical and mental health. However, aggression is sometime considered to have desirable aspects, such as being an effective source for solving complicated situations between individuals or for promoting self-development through frustration. The purpose of this study was to investigate such diverse relationships between aggression and health. Undergraduate and graduate student participants (N=286) completed questionnaires regarding aggression and Quality of Life (QOL) as an indicator of subjective health. The results showed that: 1) hostility, which is a cognitive aspect of aggression, was related to deterioration of QOL; 2) verbal aggression, which is a behavioral aspect of aggression, was related to maintenance or improvement of QOL. These findings suggest that longitudinal investigation to determine the details of the causal relationships between aggression and QOL is warranted.
