Surprisingly, little is known on the effectiveness of reward systems in prison (RSPs). This paper aims to address this gap. Method. A systematic review on RSPs was conducted, twenty one studies met the inclusion criteria. Results. Overall, findings on RSP effectiveness were mixed. Three study types were identified. Type-1 studies indicated that experimental RSPs using tokens yield positive short-term behavioral effects in individuals cognitively functioning below average. Type-2 studies indicated that non-experimental RSPs are most successful when targeting high-risk participants and include cognitive program elements. Type-3 (qualitative) studies highlight three potential moderators: a pain of self-government, perceived legitimacy, and using family contact as a reward. Discussion. As overall study quality is below average, findings should be interpreted with caution. Results were partially congruent with prior research.
