摘要：This Campbell systematic review assesses the effect of scared straight and similar programs on criminal behaviours by juvenile delinquents or children at risk of committing crime. The review summarises findings from nine studies conducted in the United States. Participants include juveniles and young adults between the ages 14‐20. A total of 946 juveniles or young adults participated in all 9 experimental studies. Scared straight interventions cause more harm than doing nothing. The nine studies provided no evidence for the effectiveness of scared straight or similar programs on subsequent delinquency. Furthermore, analysis of seven studies reporting reoffending rates showed that the intervention significantly increased the odds of offending on the part of both the juveniles and pre‐delinquents.
