What does the evidence tell us about Motivational Interviewing (MI), and what might the future of research hold?

In the final episode of the ISSUP Exchange series, Dr. Goodman Sibeko and Professor Stephen Rollnick explore the research behind MI, discussing why it remains effective across so many settings. With over 2,500 randomised trials, MI is one of the most studied approaches in behavioural health, but some of the most valuable insights come from understanding how and why it works.

They look at the importance of process research, the impact of brief interventions in emergency settings, and how MI principles are now used beyond clinical practice, including in staff development, leadership, and team culture. The episode also touches on professionalisation in addiction services, AI's potential in MI training, and how embedding empathy and autonomy into systems can support both clients and practitioners.

Whether you're a researcher, trainer, or frontline practitioner, this episode offers a thoughtful look at where MI is making a difference and how it can continue to shape people-centred care.
