“…A primary example of such a scale is the Conflict Tactics Scale [CTS: Straus, 1979], which measures acts of physical (and other forms of) aggression between partners [Archer, 1999[Archer, , 2000[Archer, , 2002. Comparable act-based scales measuring aggression between non-partners, or more generally, have been used in a range of studies over the previous 25 years: e.g., the Olweus Multifacited Aggression Scale [OMAI: Olweus et al, 1980]; the Interpersonal Behavior Scale [Mauger et al, 1980]; and the Self-Reported Aggressive Behaviour scale [Campbell et al, 1997]. The Richardson Conflict Response Questionnaire [RCRQ: Green et al, 1996;Richardson and Green, 1999] is based on earlier scales, and was explicitly designed to measure both direct and indirect forms of aggression.…”
