The purposes of this study were to develop a Japanese version of the MÜller Anger Coping Questionnaire (MAQ), and to examine its validity and reliability. Participants, 1262 undergraduate students (617 male, 645 female), were asked to complete the translated questionnaires. Factor analysis revealed four components of anger coping: Aggressivitat, Kontrollierter Affekt, Schuld, and Soziale Hemmung. Evidence for factorial validity, criterion-related validity, and external validity for three of the sub-scales was also obtained. Scale reliability was measured using Cronbach's α, and test-retest reliability was confirmed in a 16-week time frame. Results of these analyses offered evidence as to the reliability of the sub-scales. Further research concerning the relationship between AHA (Anger, Hostility, and Aggression) and health is suggested.
