Scoring / Benchmarking
Respondents are presented with a series of behaviors, and are asked to mark with a circle the number of times they did that behavior during the last 7 days (range is 0 to 6+ times).

This scale is scored by adding all responses. Possible range is between 0 and 66 points. Each point represents one aggressive behavior the student reported engaging in during the week prior to the survey. If four or more items are missing, the score cannot be computed. If three or less items are missing, these values are replaced by the respondent's average
