Process evaluation- better Flashcards
current concerns of interventions relevant to government policy
are we creating evidence based interventions
-currently a lack of applied research at population level to support specific interventions to change the behaviour of large groups of people
interventions lack of evidence of
cost-effectiveness and long-tam impact
evaluation should be
considered right at the beginning of the design process
who should be sough for evaluation
external evaluation expertise
process of intervention mapping
1) needs assessment and elicitation research
2) define measurable change objective- determine outcome evaluation
3) identification of change mechanism (logic model)- determines process evaluation
4) selection of evidence-based techniques capable of altering identified mechanism
5) identification of feasible, attractive sustainable delivery formats
6) co creation of intervention with those who will deliver and receive them
7) planning marketing, adoption and implementation
8) planning evaluation- before materials are created.
basic intervention mapping (never look past poppy iris)
1) evaluation
2) needs assessment
3) logic models
4) program design
5) program production
6) implementation
7) evaluation
twelve broad characteristic of behaviour-change interventions
- specific behaviour changes targeted
- modifiable processes operating at different levels that regulate behaviour patterns
- change techniques known to alter identified regulatory processes
- the modes or formats of delivery to be used (face-trace, telephone calls, leaflets)
- the fit between intervention components and the cultural and practical context in which it will be used
- characteristics, qualifications and training of those delivering the intervention
- intensity
- duration
- fidelity
- evaluation, including outcome process and economic evaluations
evaluations include
outcome
process
economic
intensity
the contact time of each session
dose
the amount of intervention delivered
fidelity
the extent to which the intervention is delivered as it was intended by the researchers
- where they delivered as they were designed
outcome evaluation
-does the intervention work? (efficacy vs effectiveness and observed differences and validity)
-how does it work?
effect size and clinical relevance
proces evaluation
- how does the intervention work? (mechanism/ techniques)
- who does it work for and i what setting
mechanism and techniques
mediators
group and setting
moderators
