Intervention Mapping DevelopmentQuestions that we couldnt easily answer from available resources:
THEORY
When in the planning process do I use theory toguide my decisions?
How do I know what theories and constructs to use?

EVIDENCE
How do I make use of the experience of others andthe results of program evaluations.
How do I judge the the validity and strength ofevidence?

EFFECTIVE METHODS
How do I decide what intervention methods to use? How can I get from program goals and objectives to
the specific intervention strategies for the programparticipants?
How do I link program design with programimplementation?

ECOLOGICAL APPROACH
How do I address changing the behavior of people inthe environment (i.e. make sure interventionaddresses those people who are not at risk for thehealth problem , but are important to changing
conditions that affect those at risk)?

Possible innovation in the way we do
planning :
Explication of Multilevel Environmental FactorsRelated to Health and Behavior
Explicit attempts to facilitate an ecologicalplanning approach that takes intoconsideration both the social and physical
environmental factors that influence a healthproblem

Possible innovation in the way we do
planning :
Focus on Behavior of Both the At-RiskPopulation and the Agents of Environmental
Change
Explicit definition of behavior includingperformance objectives

Possible innovation in the way we do
planning Proposed Determinants
The explicit delineation of the factors that can
be supported as [causally] related tobehavioral or environmental causes of ahealth problem
The explicit intersection of these
determinants with the performancenecessary to carry out the health behavior orchange the environmental factor MATRICES

Possible innovation in the way we do
planning :
Matrices of Proximal Program Objectives
The use of the Matrix device to plan methodsand strategies for both
The intervention itself
Adoption, implementation, maintenance and
wide diffusion of the intervention

Possible innovation in the way we do
planning:
The Difference between Methods and
StrategiesThe attempt to force a division between
theoretical methods and practical strategies

The goal of developing Intervention
Mapping was to describe and clarifythe processes that have been used to
create effective interventions.
Not to create a newprocess!

Intervention Mapping Step I
Matrices of Proximal Program Objectives
State expected changes in behavior and environment
Specify performance objectives
Specify hypothetical determinants
Create matrices (if necessary, differentiate thepopulation)

Intervention Mapping Step 2
Methods and Strategies
Brainstorm methods
Translate methods into practical strategies Organize methods and strategies by groups
of leaning objectives at each level and checkthat methods are properly operationalized

Methods and Strategies
A Method is a general
process for influencingchanges in thedeterminants of behaviorand environmental
conditions
A strategy is a practical
technique for theapplication of methodsin ways that fit with theintervention group andthe context in which the
intervention will beconducted

Intervention Mapping Step 3
Producing Program Components
Operationalize the strategies into plans that
consider implementers and sites Develop design documents and produce
materials
Pretest programs and materials with
intervention groups and implementers

Analyzing Programs
Behaviors Environmental Conditions?
What determinants are targeted?
J ustifiable determinants?
Methods matched to determinants
Methods operationalized into strategies?
