Development and cross-cultural and clinical validation of a brief comprehensive scale for assessing hostility in...

This study presents the development and validation of a brief comprehensive hostility scale. Two items of each subscale from the Buss-Perry (1992) Aggression Questionnaire, most strongly correlated with their subscale score, were selected, yielding the eight-item New-Buss. Internal reliability was .66 to .81, and full and brief scales correlated r = .92 to .94. In Study 1 (95 Israeli students), New-Buss scores were significantly higher in self-rated deviant or speeding drivers than nondeviant or nonspeeding drivers, respectively. In Study 2 (279 American students), New-Buss scores correlated significantly with Barefoot's Ho, Anger-Out, Anger-In, and Agreeableness. In Study 3 (79 Israeli patients undergoing angiography), New-Buss scores were significantly correlated with coronary artery disease severity independent of SBP in men below age 60 alone but not in women. Our findings support the cross-cultural feasibility, reliability, and concurrent, construct, and criterion validity of the New-Buss.
