Which factor is NOT used to determine a predominant aggressor?

The correct choice identifies the factor that is not typically considered when determining a predominant aggressor in domestic violence situations. The predominant aggressor analysis involves assessing various elements to establish who was the primary instigator or aggressor in a situation where both parties may have been involved in a conflict.

Historical acts of domestic violence refer to previous incidents that can establish a pattern of behavior and help inform the current situation. Statements by non-involved witnesses can provide an objective perspective on the incident, contributing valuable information that may highlight the dynamics truly at play. The extent of fear experienced by the parties involved is crucial in understanding the impact of the aggression and assessing which party may have been in a position of defending themselves rather than perpetrating violence.

In contrast, the duration of the conflict does not directly inform who the predominant aggressor is, as the length of time the altercation lasts does not necessarily equate to the level of aggression or intent behind the actions of those involved. Thus, this factor is less relevant in establishing dominance in a confrontational context.
