Theoretical framework
We designed the theoretical framework in the preparatory phase of the questionnaire studies and IM process, to be able to better identify and understand the most relevant and changeable determinants of a positive pertussis vaccination intention. Because the development of our theoretical model coincided with the developments around vaccine hesitancy in recent years, the frameworks seem to partly overlap. Based on our theoretical framework, we designed a questionnaire to be able to measure the potential determinants and quantify their influence on intention. At the same time, questionnaires measuring vaccine hesitancy and vaccine confidence have been developed in stream of the worldwide interest in vaccine hesitancy.
Recommendation 9: We recommend to assess the value of our theoretical framework for other vaccines, target groups and contexts, including the newly added constructs of decisional uncertainty and anticipated negative affect. When validated, we recommend to apply this framework in future studies on vaccination acceptance, to gain an in-depth understanding of which personal, psychosocial or organisational determinants are most relevant.
Recommendation 10: We recommend to consider the possibility of integrating our theoretical framework and the determinants matrix of vaccine hesitancy, in order to come to a comprehensive and supported framework.
Recommendation 11: We recommend to compare our questionnaire to the questionnaires measuring vaccine hesitancy and vaccine confidence, and see if there are possibilities for adaptation. Together with recommendation 10, this promotes measurement uniformity and aids the possibilities of data aggregation or metaanalysis.
Recommendation 12: The questionnaire we developed based on our theoretical framework was intended to be comprehensive and hence consisted of many questions. To facilitate future research on vaccination acceptance, it is useful to develop and validate a more compact questionnaire, which is still able to measure a complete set of determinants of vaccination acceptance.
Recommendation 13: While we recognised the importance of knowledge in the existing literature and we accounted for knowledge in the proposed vaccination programme, we did not specifically measure it in our quantitative studies. The specific role of knowledge should be assessed in the evaluation of the programme once implemented, to determine its ultimate relation with intention and vaccination behaviour.
Recommendation 14: Although we recognised the importance of trust in this thesis, we did not directly measure trust in our quantitative studies. We recommend to assess the
