BACKGROUND: Agreement about acts of aggression in couples on the Conflict Tactics Scales (CTS-2) was evaluated.
METHOD: We conducted a quota sampling method to recruit a community sample of 590 heterosexual adult couples from the Region of Madrid (Spain).
RESULTS: Prevalence rates based on the maximum dyadic report identified more aggressive behaviors than did individual reports of perpetration and victimization in men and women. Partner agreement about physical and psychological aggression was significant and moderate. However, partners agreed that Negotiation of Conflicts and Positive Behaviors assessed with the Dyadic Adjustment Scale were higher than the behaviors of the Physical Assault Scale.
CONCLUSIONS: Correction factors are provided to estimate the prevalence of aggressive behavior and injuries when we only had individual reports of aggression. Partner agreement reveals the existence of variables at the individual level that significantly influence the assessment of aggression in the couple.
