  • Being at work improves stress, craving, and mood for people with opioid use disorder: Ecological momentary assessment during a randomized trial of experimental employment in a contingency-management-based therapeutic workplace (2022, Behaviour Research and Therapy)
  • Effects of time-based administration of abstinence reinforcement targeting opiate and cocaine use (2020, Journal of Applied Behavior Analysis)
  • Abstinence-contingent wage supplements to promote drug abstinence and employment: Post-intervention outcomes (2022, Drug and Alcohol Dependence)
  • Remotely delivered incentives to promote buprenorphine treatment engagement in out-of-treatment adults with opioid use disorder (2021, Drug and Alcohol Dependence)

Silverman has collaborated frequently with several co-authors, including:
