Research Design & Number of Studies
The best evidence for BAM in young persons aged 13-18 years comes from two externally conducted Randomised Control Trials (RCT). One study included 2,740 male youth from 18 public schools in low-income, racially segregated, high-crime communities in Chicago, USA (Heller et al., 2013). The students were in 7th -10th grades, with mean age of 15.6 years. The second study included 2,064 young men from 9 public schools in low-income, racially segregated, high-crime communities, also in Chicago, USA (Heller et al., 2017). The students were in 9th and 10th grades, with a mean age of 14.8 years.
Outcomes Achieved
Compared to the control group, the following outcomes were observed:
Child Outcomes
• Significant reductions in violent crimes arrests at post-test (Heller et al., 2013), and total arrests in year 2 (Heller et al., 2017)
• Significant improvement in school engagement at post-test (Heller et al., 2013), at one-year follow-up (Heller et al., 2013), and in year 2 (Heller et al, 2017)
Parent Outcomes
None
