Illinois Bully Scale (IBS)

The Illinois Bully Scale is an 18 item, self-report measure that contains three subscales for measuring the frequency of fighting, peer victimization, and bully behavior.  Consisting of 9 items, the Bully subscale includes items that address how often a youth (8-18 years old) engaged in bullying (perpetration) behavior, primarily in the form of social aggression. Consisting of 4 items, the Victim subscale includes items that address both physical and verbal types of victimization by peers. 5 items assess physical fighting.

Scoring / Benchmarking
Scoring:
Point values are assigned to each response as follows: Never = 0, 1 or 2 times = 1, 3 or 4 times = 2, 5 or 6 times = 3, 7 or more times = 4. Summary scores for each subscale can be obtained by adding the responses for associated items.

•Bully subscale: Items 1, 2, 8, 9, 14, 15, 16, 17, and 18
•Victim subscale: Items 4, 5, 6, and 7
•Fighting subscale: Items 3, 10, 11, 12, and 13

The Bully subscale score ranges from 0-36; the Victim subscale score ranges from 0-16; and the Fighting subscale score ranges from 0-20). Higher scores reflect higher levels of bullying, victimization, or fighting.

Benchmarks:
When setting benchmarks, it is helpful to look at recent data on prevalence rates.

In 2008, at least 20 percent of children ages two through 17 experienced one or more forms of bullying during the past year (see Child Trends Databank at http://www.childtrendsdatabank.org/sites/default/files/119_tab01.pdf).

Bully Police USA has produced state-by-state estimates of children involved in bullying as bully, victim, or both. These estimates are modeled on prevalence data from a large Norwegian study. Available here: http://www.bullypolice.org/BullyingNumbers.pdf . Consult these benchmarks to help inform the benchmarks you set for your program.
