W4 planning and evaluating behaviour change interventions Flashcards
REAIM dimensions
Reach Effectiveness Adoption Implementation Maintenance
Adoption influences
*look up image
Reach
who takes part
the absolute number, proportion and representativeness of individuals participating in the intervention
Effective
the impact of an intervention on important outcomes
primary and secondary
positive and negative
planned and unplanned
Adoption
settings and agencies which take up the intervention
the absolute number, proportion and representativeness of settings/agents
Implementation
what is done
individual - participants’ experience of intervention strategies
organisation - the fidelity to the intervention protocol, including consistency of delivery, time and cost of the intervention
Maintenance
sustainability
individual - the long-term effects on participant outcomes
organisational - the extent to which a program becomes institutionalised, part of the routine organisational practices and policies
REAIM for evaluation behaviour change programs
Reach
- who participated? (number, proportion of eligible, representativeness)
Effectiveness
- what were the initial outcomes? (planned, unplanned)
Adoption
- what agencies had uptake? (proportion, representativeness)
- what intervention factors influenced uptake? (enablers, barriers)
Implementation
- what was done? (strategies, fidelity, resources)
Maintenance
- what happened in the long term? (participants, agencies)
Behaviour change interventions with high impact
- Engage a high proportion of eligible and representative people as intended, especially those most in need
- Have a positive impact on desired outcomes with minimal adverse impact and adverse unanticipated consequences
- Are adopted quickly and broadly across relevant settings/agencies which are representative
- Are delivered as intended, with high participant adherence (and are cost effective)
- Have prolonged positive effects and sustained use by agencies
Planning - reach
- Who are the intended participants?
- How will these people be accessed?
- How will potential participants become aware of the intervention?
- Are there possible equity issues for participation?
- How will the underserved be enabled to engage?
- How will the representativeness of participants be assessed?
(What is the frame of reference)
Planning - effectiveness
What are the intended outcomes
- primary (behavioural)
- secondary
How can these be assessed?
- Self report (diaries, Q/re, i/v)
- Observation
- Objective (measures)
- Records
How will unplanned outcomes be assessed?
Planning - adoption
What setting/agency could take up the intervention?
Why is that?
What is the potential appeal of this intervention TO THE AGENCY?
What intervention factors could be barriers to AGENCIES taking up the intervention?
Planning - implementation
- aim, objectives
- functions
- change techniques
- mode of delivery
- interventionist
- scheduling: duration, frequency
- necessary participant/organisational resources
Planning - maintenance
Change effects for participants
- How could these be assessed?
Ongoing use of intervention by the agency
- Necessary infrastructure and resources
- Consistency with core business
REAIM limitations
Framework not a theory
-> what not how
Reach vs adoption
