Abstract |
Evaluations of wilderness challenge programs were meta-analyzed to assess the impact on delinquent behavior. The overall mean effect size for delinquency outcomes was 0.18 (N=22), equivalent to a recidivism rate of 29% for program participants vs 37% for comparison subjects. Program length was not related to outcome among short-term programs (up to 6 weeks) but extended programs (over 10 weeks) showed smaller effects overall. However, the most influential program characteristics were the intensity of the physical activities and whether the program included a distinct therapeutic component. Programs involving relatively intense activities or with therapeutic enhancements produced the greatest reductions in delinquent behavior. |
