Abstract Background
To design an effective vaccination programme it is essential to target the most important determinants of vaccination acceptance within correctly applied behavioural change theories. Intervention Mapping (IM) is a method for systematically designing behaviour change programmes. In this article, we aim to show the application of Intervention Mapping in the planning and design of a vaccination programme, using the example of pertussis vaccination for healthcare workers (HCWs).
Methods
We applied the first 4 steps of the IM framework: 1) construct a logic model of the problem, 2) construct a logic model of change, and 3) design and 4) operationalise a preliminary version of a programme aiming to vaccinate HCWs against pertussis.
Results
The primary programme goal is to optimize pertussis vaccination uptake among HCWs who are directly involved in the care for infants younger than 6 months. We identified the most relevant and changeable determinants that would influence pertussis vaccination acceptance among these HCWs, and determined specific behavioural and change objectives for HCWs in order to achieve the programme goal. On the basis of a literature review, behavioural change theory and consensus in the planning group, we decided on the final programme content, including: an invitation letter, an information folder, website and posters, and a tool assisting online deliberation. A pilot test could not be planned and implemented within the project’s timeline because a positive advice from the Health Council of the Netherlands was not issued until June 2017.
Conclusions
Based on the application of IM for systematic intervention development we designed a pertussis vaccination programme for HCWs. By following the IM protocol, we were able to develop a theory- and evidence-based vaccination programme that fits the characteristics of the target population and intervention context.
