Alejandro sits down with Andrew Harding, Lecturer in Health Inequalities at Lancaster University, to unpack one of realist research’s most defining ideas: Context–Mechanism–Outcome (CMO) configurations.
In this lively and practical conversation, Andy reflects on his decade-long realist journey, from PhD student to supervisor, sharing how CMOs have evolved from textbook theoryto hands-on analytic tools. Together, they explore what it really means to “think with CMOs,” how to avoid common traps when building them, and why flexibility and creativity are vital in realist analysis.
Drawing on real-world examples from his own work on housing and ageing, Andy illustrates how subtle shifts in reasoning and context can reshape outcomes. The discussionmoves beyond formulas, revealing CMO configuration as both method and mindset, a way of thinking that helps researchers make sense of complexity.
Whether you’re new to realism or deep into your thesis, this episode offers clarity, confidence, and a few “light-bulb” moments for anyone trying to decode what makes interventions tick.
Alejandro sits down with Ray Pawson, Emeritus Professor at the University of Leeds and one of the founding thinkers behind realist evaluation and realist synthesis.
In this landmark conversation, Ray reflects on nearly three decades of realist evaluation and realist synthesis, from its beginnings in the 1990s to its role today across healthcare, policy, and social research. Together, they explore how realist evaluation first challenged the dominance of experimental methods and why healthcare became a crucial testing ground for these ideas. Ray discusses his notion of “Groundhog Day” in evaluation and the need for cumulative learning across studies, as well as the potential of realist synthesis as “evaluation without infrastructure.”
Looking ahead, he shares his vision for expanding realist work from programme evaluation to policy evaluation, urging researchers to think beyond isolated projects and towards a broader science of learning about what works, for whom, and in what circumstances.
Throughout the conversation, Ray’s characteristic humour and deep insight shine through, offering both historical perspective and practical wisdom. From his reflectionson the past to his hopes for the future, this episode captures what it truly means to “think like a realist.”
Alejandro sits down with Suzanne Jackson, Associate Professor Emerita at the Dalla Lana School of Public Health, University of Toronto. Suzanne has been a pioneer in participatory research for decades, and her work has shaped how realist approaches can be applied in complex community and health promotion contexts.
Together, they dive into the art (and challenge) of linked coding of context–mechanism–outcome configurations in realist research. From the early development of dyads and triads, to recent adaptations making the method more participatory and responsive to community needs, Suzanne takes us through the evolution of this approach and the lessons learned along the way.
We hear how she has applied this method in diverse projects, from early parenting programmes in Toronto, to community resilience research during COVID-19, and what these experiences reveal about the practical realities of applying realist evaluation in complex, real-world settings.
Suzanne also shares practical advice for researchers and evaluators: how to align definitions across coding teams, why early discussions are crucial for consistency, and her top three tips for making sense of programme theories through linked analysis.
Alejandro sits down with Zoe McCormack, a PhD researcher at the Royal College of Surgeons in Ireland, whose very first PhD paper, a realist review , has just been published.
Together, they dive into the art (and challenge) of building programme theory in realist research. From defining what programme theory really means, to navigating the messy process of scoping and refining ideas in complex educational contexts, Zoe opens up about the highs and hurdles of her research journey.
We hear how stakeholder engagement shapes more meaningful theories, why exposure to lived experience is so vital for building empathy in mental health education, and what Zoe’s findings reveal about preparing health profession students to better understand and support mental wellbeing.
Zoe also shares practical advice for anyone grappling with realist evaluation and synthesis: her step-by-step tips for developing theories, the lessons she’s learned from combing through hundreds of articles, and her top three takeaways for building programme theories that actually hold up in practice.
How do you choose the right analytical strategy for a realistevaluation — and why does it matter so much?
In this thoughtful and practical conversation, Alejandro isjoined by Steffen Bohni, Director General of Denmark’s National Research Centre for the Working Environment, to explore the critical role of analytical strategies in realist evaluation and synthesis. With over 25 years in evaluation, Steffen shares lessons from his collaborations with Sebastian Lemire and insights from two decades of realist literature.
From the importance of methodological congruence tonavigating real-world constraints like time, budget, and messy data, Steffen offers a clear-eyed view of what it takes to design analysis that is both rigorous and realistic. He explains when and why techniques like Qualitative Comparative Analysis, process tracing, link coding, or structural equation modelling might be best suited — and how to combine them without losing analytical coherence.
You’ll hear practical tips for planning analysis from dayone, managing complexity with a feasible number of CMO configurations, and staying aligned with realist principles even under pressure. Whether you’re new to realist evaluation or refining your analytical approach, this episode will give you a grounded framework for making your analysis work harder and smarter.
What does it really mean to generalise in realist research? How do we move from rich, contextual description to insights that are genuinely transferable?
In this mind-expanding episode, Alejandro is joined by Assistant Professor Dimitri Renmans — health systems researcher and co-founder of the All-Realist Group — to unpack the challenge of generalisation without falling into the trap of purely statistical thinking. From the difference between statistical and theoretical generalisation to what “abstraction” really means (hint: it’s not just about categories), Dimitri offers practical ways to preserve context while still building knowledge that travels.
Drawing on his work developing “mechanism concepts,” Dimitri shares why they matter for theory-building and how they can help researchers move their CMOCs towards robust middle-range theory.
Whether you’re grappling with generalisation, refining mechanism development, or simply looking to sharpen your realist research practice, this episode will give you fresh tools and perspectives.
What is a realist interview, really? How do we design interviews and focus groups that go beyond collecting stories to actually testing and refining theory?
In this engaging and thought-provoking episode, Alejandro is joined by Professor Ana Manzano — a leading thinker in realist methodology — to unpack exactly that. From the roots of theory-driven interviewing to the practical realities of asking “how” and “why,” Ana shares insights that will change how you think about realist research.
Drawing on decades of experience in evaluating complex health and social interventions, Ana explores how realist interviews work, when (and why) they don’t, and what ittakes to build genuinely dialogical, theory-informed conversations with stakeholders.
Whether you’re planning your first realist interview, refining programme theory, or simply looking for practical wisdom from someone who's been there — this episode is for you.
How can realist approaches become more accessible andimpactful for the communities they aim to serve? What does it mean to truly collaborate with practitioners, students, and local systems when doing realist evaluation?
Join Alejandro and Dr Kevin Harris for an energising and thought-provoking conversation that explores just that. From Kev’s roots in sports and social change to his pioneering work with Sport England, this episode delves into practical ways to demystify realist research, engage stakeholders meaningfully, and develop evaluation strategies that are both rigorous and equitable.
Whether you're navigating a realist PhD, supportinglocal systems change, or just trying to make evaluation more human and honest—this episode is for you.
In this inspiring episode, Alejandro is joined by Kristin Xenos, a practising pharmacist, realist PhD researcher and cohost of the clinical pharmacy podcast The Purple Pen Podcast to talk about the real journey into realist methodology—complete with uncertainty, lightbulb moments, and growing confidence.
Kristin shares her experience transitioning from a traditionally positivist discipline into realist thinking as she tackles a complex topic: pharmacist prescribing education.
Kristin's reflections are honest, encouraging, and deeply relatable—especially if you’ve ever doubted your method, questioned your scope, or needed a reminder that learning feels messy for a reason.
Highly recommended for PhD students, educators,healthcare researchers, and anyone exploring realist synthesis from scratch.
