Background and Purpose: Buss & Perry (1992) developed the Aggression Questionnaire (AQ) in the UK and verified its reliability and validity. The Japanese version of the AQ (AQ-J) was later developed and used for several interventions in psychiatric nursing. However, its reliability and validity have not been verified. Therefore, in this study, we aimed to verify the reliability and validity of the AQ-J for people with mental illnesses during treatment.
Purpose of Research: To verify the reliability and validity of the Japanese version of the aggression questionnaire in people with mental illness during treatment.
Subjects and Methods: This research targeted about 130 adults with mental illness hospitalized in a psychiatric medical institution. The study involved an initial survey followed by a retest after two weeks (test-retest method). The State-Trait Anxiety Inventory-Form JYZ (STAI-JYZ) was used to investigate the concurrent validity of the AQ-J version. All statistical analyses were performed using SPSS Ver. 25.
Results: In total, 115 valid responses were received for analysis (66.09％ response rate). The Cronbach’s alpha coefficient for the AQ-J was 0.91. There was a significant positive correlation at the 1％ level between the STAI and the AQ-J (r = 0.45, p＜0.01) results.
Discussion: As the alpha coefficient of the AQ-J was above 0.70, the internal consistency is considered to be sufficient. There was a significant positive correlation between the STAI and the AQ-J.
Conclusion: The reliability and validity of the AQ-J were verified for people with mental illnesses during treatment.
