Key Points Question What are the long-term effects of a crime prevention program on mortality? Findings In this longitudinal follow-up of a randomized clinical trial of 506 boys who received individual counseling through a range of activities and home visits for an extended duration vs no special services, no important differences were found between treatment and control group participants for mortality outcomes 72 years after the intervention, suggesting that earlier observed iatrogenic effects did not persist. Meaning Continued research on studies with iatrogenic effects is needed to better understand why and when some programs cause harm and to help mitigate their perpetuation.
