Research Question: What are the effective* and cost-effective choice architecture** interventions to promote healthier behaviours or reduce health risk behaviours for smoking, alcohol, food intake and physical activity? https://www.nihr.ac.uk/documents/1453-choice-architecture/11680
*‘Effectiveness’ in this context relates not only to the size of the effect, but it also takes into account any harmful/negative side effects.
** The term ‘choice architecture is defined as ‘Interventions that involve altering the properties or placement of objects or stimuli within micro-environments with the intention of changing health-related behaviour. Such interventions are implemented within the same micro-environment as that in which the target behaviour is performed, typically require minimal conscious engagement, can in principle influence the behaviour of many people simultaneously, and are not targeted or tailored to specific individuals’ (Hollands et al., 2013).
Population: General population or relevant target population. Researchers to specify and justify.
Intervention (non-NHS): Choice architecture interventions for smoking, alcohol use, food intake or physical activity.
Comparator: Non provision/usual practice or other interventions.
Outcomes: Behaviour change in smoking, alcohol use, food intake or physical activity.
Intervention (non-NHS): Choice architecture interventions for smoking, alcohol use, food intake or physical activity.
Comparator: Non provision/usual practice or other interventions.
Outcomes: Behaviour change in smoking, alcohol use, food intake or physical activity.
Commissioning Brief: Studies should generate evidence to inform the implementation of single or multi-component interventions. Studies may include evidence syntheses, studies evaluating interventions, including trials, quasi- and natural experimental evaluations, and feasibility and pilot studies for these. We welcome applications for linked studies (e.g. pilot + main evaluation). Secondary analyses of existing epidemiological data and/or impact modelling studies may also be funded. We encourage the adoption of a systems perspective where appropriate to the study context. In all cases a strong justification for the chosen design and methods must be made.
The primary outcome measure of the research, if not necessarily the intervention itself, must be health-related. The positive or negative impacts of the intervention, including inequitable outcomes should be considered. Researchers are asked to indicate how long-term impacts will be assessed. All applications should identify underlying theory and include a logic model (or equivalent) to help explain underlying context, theory and mechanisms. Proposals should ensure adequate public involvement in the research.
For all proposals, applicants should clearly state the public health utility of the outcomes and the mechanisms by which they will inform future public health policy and practice. Details about the potential pathway to impact and scalability of interventions, if shown to have an effect, should be provided, including an indication of which organisation(s) might fund the relevant intervention(s) if widely implemented.
Representatives of policy or practice communities relevant to the project should be directly engaged or involved with the development and delivery of PHR research because this produces research that is more closely grounded in, and reflective of, their concerns and makes the subsequent uptake and application of research findings more likely. By policy or practice, we mean any organisation that is involved in shaping policy or delivering public health services relevant to the research, whether at local or national levels. This might include local authorities, charities, voluntary organisations, professional bodies, commercial organisations, governmental and arms-length bodies.
