Scoring
editTotal scores on the MOAS range from 0-40, with a higher score indicating more aggressive behavior. Each checked statement receives 1 point, then points from each section are summed.
Section scores are weighted as follows:
- Scores from the "Aggression Against Property" section multiplied by 2;
- Scores from the "Autoaggression" section multiplied by 3;
- Scores from the "physical 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.
