Conclusions
violent crimes
The problem of offender attrition from clinical trials and programmes is ongoing and a serious concern given it is linked to recidivism. Identifying ways to reduce the attrition from clinical trials of offenders who commit violent crimes is vital. This study identified a number of risk factors that support researchers to predict attrition of men with a history of violence from clinical trials. Awareness of these factors can support researchers working with samples that are justice-involved to determine, at baseline, participants for whom additional provisions may optimise retention.
