The '''Modified Overt Aggression Scale (MOAS)''' is a four part behavior rating scale designed to measure four types of aggressive behavior as witnessed in the past week.<ref name=MOAS1>{{cite journal|last1=Alderman|first1=N|last2=Knight|first2=C|last3=Morgan|first3=C|title=Use of a modified version of the Overt Aggression Scale in the measurement and assessment of aggressive behaviours following brain injury.|journal=Brain injury|date=July 1997|volume=11|issue=7|pages=503–23|pmid=9210987|accessdate=9 July 2015|doi=10.1080/bij.11.7.503.523}}</ref> Each section consists of five questions, with the first section regarding verbal aggression, the second section focusing on aggression against property, the third section measuring autoaggression, and the fourth section concerning physical aggression.

The MOAS was originally intended for use by physicians in a clinical setting, but parents may also use it to track aggressive behaviors in their children over time. It is particularly helpful in assessing aggressive behaviors in patients with [[traumatic brain injury]] (TBIs). The scores of the scale have shown good [[reliability (research methods)|reliability]] and [[test validity|validity]] across multiple different study samples<ref name="MOAS1"/><ref name="ReferenceA"/>

Section scores are weighted as follows:

*Scores from the “Aggression"Aggression Against Property”Property" section multiplied by 2;

*Scores from the “Autoaggression”"Autoaggression" section multiplied by 3;

*Scores from the “physical"physical aggression”aggression" section multiplied by 4.

Weighted score are then added together to yield the total score. A scoring summary can be found at the bottom of the measure to aid in interpretation of responses.
