Background: Risky sexual behaviour (RSB) is a serious public health problem for adolescents. We examined whether a contingency management intervention implemented by juvenile probation officers (JPOs) targeting substance use also impacted RSB.
Methods: A total of 218 adolescents on probation were randomly assigned to contingency management or to probation as usual.
Results: The substance use intervention delivered by JPOs reduced rates of RSB over time (β =-0.32, P =0.041 at 6months; β =-0.32, P =0.036 at 9months).
Conclusions: Adolescents receiving a substance use intervention from JPOs demonstrated reduced/prevented RSB. Interventions targeting single risk behaviours in juvenile probation populations should measure changes in other risk behaviours . Under-resourced communities lacking clinicians might consider JPOs delivering interventions.
