The aim of this study was to develop a set of measurable indicators to infer the presence and the extent of EIPM in public health policies in order to fill a recognised gap. The study led to the development of 25 validated indicators for EIPM. Several features of these indicators are noteworthy. The international REPOPA indicators have been co-produced and validated by a panel working at international level, bringing together a large number of key experts geographically dispersed in six European countries, including also international organisations – a particularly relevant aspect if we consider that initiatives related to EIPM in the European Region are usually scattered and often stand-alone [
71]. Moreover, the indicators were considered feasible and relevant for those working in an array of government sectors.
Using the indicators to foster EIPM
The validated indicators for EIPM are intended to be used by decision-makers, researchers and other stakeholders at various stages of a policy-making process. Measurable indicators, by giving objective data, could help inform the design, implementation, and monitoring and evaluation of interventions to foster EIPM.
The indicators are particularly useful for evaluating public health and physical activity policies, either by the organisation responsible for the policy or by other stakeholders such as external evaluators or research institutes. They can support EIPM already during the agenda-setting phase, helping to identify crucial elements to infer the presence and the extent of EIPM to be considered. During the development of a policy, the indicators can be used to monitor enablers of or barriers to EIPM in the policy process, giving the measure of their occurrence, making it possible not only to assess whether, and to what degree, a policy is or is not being informed by evidence, but also to discover why and how, possibly allowing adjustments. The indicators can also be used to evaluate the extent of EIPM of an already implemented policy by the organisation responsible for the policy or other administrative or research bodies. Moreover, policy evaluations using the indicators can also provide valuable insights for future policy processes, also helping to infer if the policy has created new evidence.
Besides evaluation purposes, the indicators can form the basis for EIPM recommendations, implying actions that, if accomplished, would foster EIPM. The indicators may also be the basis for an intervention and for active, critical reflection on how and why EIPM might be addressed, as already shown in literature for other validated knowledge translation tools [
14]. Therefore, the use of international REPOPA indicators for EIPM may support EIPM processes, ensuring not only that the policy is informed by evidence, but also that evidence is used instrumentally to support the selection of activities to be implemented [
36,
65,
72,
73], and not selectively to justify an already made decision [
1,
74].
The availability and use of the indicators proposed in this study may contribute to an organisational culture where extended value is given to the use of evidence for decisions. Others have shown that awareness of an indicator may lead policy-makers to perceive that a problem exists, to change the way they view the problem or to potentially focus the options they see as suitable solutions [
75]. In this way, the indicators could also impact on stakeholders’ frameworks of thinking [
56], and generate new norms for EIPM within governmentally broad social norms [
54].
Furthermore, international REPOPA indicators are a valuable resource for EIPM beyond physical activity and the health field as they attain to transversal approaches to policy-making, enhancing their use for EIPM in other sectors. This is firstly due to the circumstance that all sectors use policy-making cycles with common elements. Moreover, this potential transferability of the indicators was enhanced by the variety of areas of competence and roles among Delphi panellists and the cross-sector approach that was followed and examined during the REPOPA project [
26,
50,
63,
76].
Implications for the uptake of REPOPA indicators
A first step towards the practical application of the international REPOPA indicators for EIPM has already been performed by testing them within national conferences held in the six REPOPA countries (to be presented in a later manuscript); based on these national conferences, evidence briefs and guidance resources for the use of the international REPOPA indicators were developed.
According to WHO Regional Office for Europe [
71], many tools to support EIPM are already available but are not widely used, and more research and development should continue, including evaluation of new and existing tools [
77]. Therefore, institutional support and incentives [
78,
79] such as funding or other stimuli for the individuals to foster EIPM could be considered [
80]. Health systems that provide strong incentives for dialogues between policy-makers and researchers through formalised processes and enabling structures and environments are actively facilitating knowledge generation. Formalised processes should include explicit incentives to demand and use evidence, as well as time and space for inter-linkages between policy-makers and researchers [
43].
Specifically, we think that new approaches for institutionalisation of the indicators would be required, including what employees are rewarded for. A proposal would be to build in a requirement for an assessment of indicators on EIPM into routine job performance. Our suggestion related to the international REPOPA indicators, validated by this study, is to foster their joint use by policy-makers and researchers, as a way to encourage joint researcher–policy-maker teams – a possibility given by the fact that the indicators were jointly developed with the contribution of both researchers and policy-makers, also in line with the WHO recommendations of involving both researchers and policy-makers while developing tools [
71]. Indeed, strengthening the interactions between researchers and policy-makers has been described as a potential solution to foster EIPM [
22,
24,
81], to such an extent that, according to the WHO Regional Office for Europe, it should be required among the actions to foster EIPM for policy development by the establishment of a legal framework to support the use of evidence [
71]. This issue is also reflected in several indicators retained in the final set of international REPOPA indicators that imply a relationship between researchers and policy-makers, also addressing the well-characterised communication gap between them [
5,
14,
22,
24,
48,
69,
82]. Current views, which are reflected in the final set of indicators, suggest that EIPM-oriented communication between research and policy-makers should be systematic and continuous, consisting of a collaborative approach towards using knowledge in real-world settings, adapting research questions to policy needs and helping policy-makers to interpret research findings [
6,
42,
43,
61,
72,
74,
78,
83‐
85].
Moreover, the future use of indicators is facilitated by the availability of a reliable version of the indicators in six country languages (in addition to English, Danish, Dutch, Finnish, Italian and Romanian). Although we did not provide back translation from the six national languages to English, the methodology adopted, involving two researchers external to REPOPA project per country for feedback regarding the comprehension and intelligibility of the questionnaires and indicators, can be considered as an initial step toward validation of the six versions of the set of indicators. This process of validation continued within the national conferences held in the six REPOPA countries and with the analysis and comparison of their results.
According to WHO Regional Office for Europe [
71], existing evidence and tools for EIPM should be available in local languages and sharing lessons and learning from country experiences is important as an action to build EIPM capacities, in particular in assessing and comparing EIPM practices across countries.
Finally, according to the literature [
86,
87], processes of interaction, discussion and exchange are more effective to promote learning than those based on summarising research, disseminating papers and commissioning reports. In this sense, as the REPOPA international Delphi process has the added value of being a research work and a first dissemination action at the same time, the REPOPA indicators have already started spreading.
Strengths and limitations
Two main strengths of the study are the quality of the panel, including experts coming from different areas of competence and different geographical contexts, and the unusually high response rate obtained in both the first and second round of the Delphi (92.7% and 87.8%, respectively) [
32,
88,
89]. Reaching this goal was supported by a coordination strategy that involved local management of country panellists by leads in each of the participating countries and Delphi coordinators supporting the local managing process. A possible limitation is that, in order to make the indicators adaptable to various contexts, we did not define specific units of measurement (e.g. Boolean, numerical, percentage values) and baselines (e.g. specific values to be reached to assess the presence of EIPM) to be assigned to each indicator – these should be established by the users with reference to the context of a specific health organisation or policy in a given territory. At the same time, psychometric assessment of the indicators could be performed in order to deeply understand latent factors in the indicators in view of improving their implementation in various health and research organisations, as reported in the literature for other tools [
90].
Implications for future research
Although the process of contextualising the indicators in different countries has already started by means of the national conferences held in the six European countries within the REPOPA project, further adaptations might be needed to enlarge the environments where this set of indicators can be applied, especially with reference to the specific contexts of resource scarcity and high burdens of disease in low- and middle-income countries, where evidence uptake to support effective and efficient health systems interventions is crucial to reduce health inequities [
43] and EIPM might face specific barriers to be considered. In low-resource settings, among the variety of specificities to be kept in mind while dealing with EIPM, a further issue may concern the interface between national policies and the policies of international agencies.
At the same time, the implementation of the indicators within a specific health policy or organisation is still to be tested. Future empirical studies should test the proposed indicators in actual policy processes to further assess their usability and help to understand how to integrate them in the regular business of an organisation. This testing should also involve policies not strictly related to the health field in order to verify the transferability of the indicators to other sectors.
Finally, further implementation research would be required to examine processes necessary to stimulate the use of the indicators by researchers, policy-makers and other stakeholders.
