Buss-Perry Aggression Questionnaire (BPAQ)
aggression, anger, suspiciousness, hostility
Buss and Perry rewrote the new edition of the aggression questionnaire, previously known as the hostility questionnaire [The validity and reliability of the aggression questionnaire are adequate. Retest coefficients for four subscales (with a 9-week interval) range from 0.80 to 0.72, and there is a 0.38–0.49 correlation between the four subscales. The internal validity of the scale was determined using Cronbach’s alpha coefficient, and the findings revealed that the internal consistency of the physical aggression subscale was 0.82, verbal aggression was 0.81, anger was 0.83, and hostility was 0.80 [In a study titled Reliability and Validity of the Buss-Perry Aggression Questionnaire, Samani[25] used factor analysis to extract four behavioral factors: anger, physical and verbal aggression, resentment, and suspiciousness. This questionnaire had a test-retest reliability value equal to 0.78. The strong correlation of the components with the overall score of the questionnaire, the low correlation of other factors, and the alpha coefficient values all show that this questionnaire is adequate and effective for researchers, professionals, and psychologists in Iran [25]. Researchers and professionals may rely on the reliability and validity of the Buss-Perry Aggression Questionnaire.
