Compared to a control group, mentored youth were:

- less likely to hit someone

- less likely to engage in problem behavior

- less likely to commit misdemeanors or felonies

- committing less serious offenses

- less likely to commit a major offense in the program year (37.5% vs. 64%), or in the program year or two years later (56% vs. 78%), (only for mentored youth with a history of committing major offenses)

BUT, program participation did not impact behaviors such as:

- stealing or damaging property

- number of times youth sent to office

- doing risky things, fighting, cheating

- using tobacco

Youth without a prior major offense were more likely than a control group to commit a major offense in the program year (16% vs. 7%), or in the program year or two years later (23% vs. 16%)
