Table 1 RE-AIM dimensions and corresponding questions
RE-AIM Dimension | RE-AIM questions | Study research question |
|---|---|---|
Reach | What percentage of potentially eligible participants are recruited, and how representative are they? | How many people are judged to be at risk for IGR, and how many were recruited? How representative are those recruited of the local population? How many people were recruited from high-risk populations? Which treatments did participants enter? Which referral route was most effective in recruitment of eligible participants? |
Effectiveness | What impact did the programme have on targeted outcomes? | Clinical outcomes for individuals were not evaluated in this study. |
Adoption | Which setting and intervention agents were involved and how representative are they? | What features of the participating services were considered crucial to delivery? Did engagement vary across the different services? What characteristics of services are required if the intervention was to be adopted elsewhere? |
Implementation | Was there fidelity to the intervention, and what local adaptation occurred? | What were the barriers and facilitators to delivering the intervention as planned? How did contextual factors impact on delivery? How was the intervention tailored to different populations? Was delivery adapted over time, and if so why? |
Maintenance | Individual level – extent to which behaviours are maintained long term; Institutional level – extent to which programme is sustained over time. | Individual: which factors are associated with adherence to treatment – does referral route impact on this? Institutional: What factors will impact on continuation of the programme? What resources are considered necessary to improve delivery? |
