This Rapid Evidence Assessment (REA) explores the factors related to involvement in and desistance from Serious Organised Crime (SOC). There is a need for evidence-based practice to underpin the work and products being developed for the management and rehabilitation of individuals involved (or at risk of being involved) in SOC. The current review sought to increase understanding of the factors associated with organised crime involvement. The REA reflected the wide variety of factors cited in the literature, highlighting a combination of an individuals’ personal background and skills, and the social relationships they develop in different settings of their lives. The challenges when considering the management and rehabilitation of this population have also been highlighted. The findings of this review can inform future research and the shaping of future policies and interventions. The findings could also be used to inform the development of SOC specific interventions, which will target the needs of this population.
