Sanjeev Sridharan and Janet Smylie Centre for Research on Inner City Health University of Toronto Benita van Wyk, Feedback Research & Analytics Unpacking the notion of program theory from a complexity lense: Can indigenous and cross-cultural perspectives help?
Outline • 1. Why is program theory important and useful? • 2. What are the limitations of the standard approach to program theory? The view from evaluation • 3. Ideas for a potential research project

The important questionsWhat is a program?Does the nature of the causal assumptions make a difference in the way we plan programs and evaluations? Dealing with complexity
Dealing with complexity An Example of a complex intervenion
The nature of the causal problem • Note that the causal assumptions are not clearly specified • Most assumptions are implied and of the form: • If (A and B and C and D and E and at time T) then good outcomes might result • The problem: • Causal contingencies not clearly specified or understood • Dynamic complexity not well understood
The incompleteness of program theories • The logic model while complex is still incomplete • A policy such as the smoking ban might lead to proximal impacts through perhaps an uncomplicated pathway; however the logic of the causal chain for intermediate and long-term outcomes might be incomplete • Additional “programmatic” inputs might be needed. • Information on the nature of such additional interventions can perhaps come from a synthesis of literature plus additional dialogue with stakeholders with an intimate knowledge of the processes by which programmes works.
Defining a complex intervention (MRC, 2000) • “The greater the difficulty in defining precisely what exactly are the ‘active ingredients’ of an intervention and how they relate to each other, the greater the likelihood that you are dealing with a complex intervention.”
System Dynamic Approaches (Sterman, 2006) • Constantly changing; • Governed by feedback; • Non-linear, History-dependent; • Adaptive and evolving; • Characterized by trade-offs; • Policy resistance: “The result is policy resistance, the tendency for interventions to be defeated by the system’s response to the intervention itself.”
Features of complex health interventions (Pawson et al., 2004) • The intervention is a theory or theories • The intervention involves the actions of people. • The intervention consists of a chain of steps • These chains of steps or processes are often not linear, and involve negotiation and feedback at each stage. • Interventions are embedded in social systems and how they work is shaped by this context. • Interventions are prone to modification as they are implemented. • Interventions are open systems and change through learning as stakeholders come to understand them.
An additional purpose of evaluation for complex interventions • Explication • Why? • Multiple components– be explicit about the “active ingredients” • Timeline of impact unclear • Non-uniformity– Contextualizing • Stakeholder involvement: Co-construction of intervention
On causality and complexity • Does a cause operate the same way in simple systems as compared to complex systems? • Are there different kinds of causes? • E.g. Famines • Precipitating causes • Amplifying causes • Causes of vulnerability • Innovations in evaluation design and approaches
So what do programmes do? • A need for a richer vocabulary on programmes as causes– can we learn from other sciences such as evolution or chemical kinetics? • Different metaphors: Programmes as catalysts, programmes as foundations, programmes as operating systems • Understanding complexity in multiple light • The system-as-cause • Understanding dynamic complexity

If (A and B and C and D and E and at time T) then good outcomes might result What does this really mean? Unpacking the complexity of the change process What is missing in our understanding of how programs work? Unpacking the causal contingencies of change
Seeing and understanding connection “You think you understand two because you understand one and one. You think you understand two because you understand one and one. But you must also understand ‘and’.” You think you understand two because you understand one and one. But you must also understand ‘and’.” -- Sufi Saying
Why sustaining programs might be key to success Going further – sustainability of programs at the individual level – the critical importance of Continuity of Care 1. The role of sustainability
2. The limited understanding of heterogeneity Heterogeneity of needs Heterogeneity of mechanisms of change Heterogeneity of interventions
3. The role of connectivity between interventions Far too much focus of most evaluations on a single intervention as the unit of analysis Understanding connectivity between programs
4. Understanding the relationship between multiple levels of interventions Many complex interventions require programming at the community, neighborhood, school and individual level Multilevel alignment across the interventions
5. Understanding Dynamic Complexity Timeline of impact Developmental Synergies
5. Coordination complexity The advantages of partnerships are poorly understood More importantly, collaborative advantages of individual recipients rarely made
6. Sequential Complexity Relationship between sequences of interventions poorly understood Most of our methodologies are extremely limited in understanding such relationships
7. Structural complexity Policy resistance Translating programs to fit within the structures The system-as-cause
Next Steps Identify partners Identify concepts from Evaluation and Indigenous/Cross-Cultural Field/Literature that can help enhance the concepts Translate concepts into practical testable experiments
