Syllabus: How Can Effective Psychological Care Reach More People?
Follow the distinction between changing a treatment and changing how it reaches people.
Why you’re reading it. Open the service question without assuming that one delivery format will suit everyone.
A question to consider. A community has long waiting lists and poor transport. Which two delivery changes might address different barriers, and who could still be excluded?
Why this reading
An effective therapy cannot help people it never reaches. Kazdin and Blase distinguish treatment content from delivery and argue for multiple ways of reaching different populations.
Before you read
A delivery model concerns who provides an intervention, where and how. Population burden includes disability and distress beyond the outcomes of people enrolled in a trial. Prevention and treatment can affect different parts of that burden.
Read for
- Identify the barriers each proposed delivery model could address—and the people it could still miss.
- Separate evidence for an example from the wider argument for combining delivery models.
Consider afterwards
- How could two programmes with different average effects contribute differently to population health?
- What would you measure before claiming that a new delivery format reduced unmet need?
Editorial context
This 2011 agenda uses diverse examples rather than testing a complete service system. Its statistics and technologies describe that period. Broad reach, low cost and retained effectiveness require evidence in each setting. Shoham and Insel’s commentary presses the question of whom simpler interventions serve adequately.
