What is a determinant in implementation science?
A factor that influences whether an intervention is adopted, used, or sustained.
Determinants explain patterns of use.
What is a barrier?
A perceived obstacle reported by stakeholders.
Barriers are clues, not explanations.
What is a root cause?
A deeper systemic condition that generates repeated problems.
Root causes shape multiple determinants.
Why do teams over-focus on barriers?
Because barriers are easy to hear and list.
Barrier lists feel productive but stall progress.
Why are determinants more useful than barriers?
Because determinants explain why barriers appear.
Design should target determinants, not complaints.
Why are root causes hard to identify?
Because they sit outside individual control.
Root causes persist across projects.
How do barriers, determinants, and root causes relate?
Barriers are symptoms; determinants are conditions; root causes are generators.
Confusing levels leads to weak fixes.
Why is “lack of time” rarely a determinant?
Because time pressure reflects deeper system design.
“Too busy” hides structural decisions.
Why is “lack of training” often misdiagnosed?
Because knowledge is usually not the constraint.
If people know but can’t act, training won’t help.
What does a good determinant sound like?
A condition that explains when and for whom use succeeds or fails.
“Works on day shifts but not nights” signals a determinant.
Why are determinants more actionable than root causes?
Because determinants are closer to design decisions.
You design against determinants.
When is root-cause thinking still useful?
When patterns repeat across multiple interventions.
Repeated pain signals a root cause.
Why do barrier-based solutions often fail?
Because they treat symptoms, not systems.
Barrier fixes decay quickly.
What’s wrong with asking “What’s the main barrier?”
It assumes a single cause in a complex system.
Implementation problems are multi-determinant.
How does human factors thinking align with determinants?
Both focus on constraints shaping behaviour.
HF insights often identify key determinants.
Why is blaming individuals a determinant error?
Because behaviour is shaped by context.
Blame hides real leverage points.
What is a classic example of a hidden determinant?
Unrecognised role conflict.
Role ambiguity drives workaround behaviour.
Why do determinants often differ across sites?
Because context is not uniform.
Same intervention, different constraints.
What does “diagnostic depth” mean?
Moving beyond surface complaints to systemic conditions.
Depth improves strategy fit.
Why are determinants dynamic over time?
Because systems adapt and pressures shift.
Yesterday’s fix may fail tomorrow.
How should barriers be used productively?
As entry points to determinant analysis.
Ask “what makes that hard?”
What does a determinant-focused question sound like?
What conditions make this easy or hard?
Better questions reveal better strategies.
Why is root-cause language risky in implementation?
Because it implies single, fixable causes.
Systems rarely have one root.
How does this deck prevent “training creep”?
By distinguishing knowledge gaps from system gaps.
Training should be a last resort.
