pertussis cocooning, previous acceptance of influenza vaccination and perceived recommendation (by national or local authorities) are apparently common determinants that are also reflected in our potential determinants of intention (Mir et al. 2012, Lu et al. 2014, Tuckerman et al. 2015, Paranthaman et al. 2016). In our study, the association between previous influenza vaccination and intention was only significant for the midwives. Perceived recommendation can be understood as part of the social norm, which is consistent with our study.
Anticipated regret or negative affect (especially regarding non-acceptance) has been considered a determinant of vaccination behaviour before (Lagoe et al. 2015, Leder et al. 2015). The additional value of anticipated negative affect these studies suggested agrees with our findings.
We added decisional uncertainty as a determinant because of the profound influence it showed in our previous qualitative research. To our knowledge, no other studies have considered decisional uncertainty as a determinant, but the difficulty of deciding whether to accept vaccination has been described previously (Wroe et al. 2004). Peadon et al. (Peadon et al. 2007) state that non-acceptors of pertussis vaccination need more information for their decision. The finding in this study that decisional uncertainty is uniquely associated with the intention to accept, matches our previous study (Visser et al. 2016). This aligns with studies assessing the effect of decision aids on vaccination, which showed a reduction of decisional conflict and an increase in uptake(Chambers et al. 2012, Shourie et al. 2013). The decisional uncertainty in HCWs regarding their own vaccinations raises concerns on how this potentially impacts their role in promoting vaccination among their patients, such as new parents making vaccination decisions for their children.
In all our target groups, attitude, anticipated negative affect regarding non-acceptance (regret), and decisional uncertainty were significantly associated with intention. Social norm, perceived capacity, and anticipated affect regarding acceptance were only significantly associated with intention in a specific target group. First, social norm only showed a significant association for maternity assistants and paediatric nurses, not for midwives. It could be argued that the autonomous practice of independent midwives contributed to this finding. Second, perceived capacity did not influence the paediatric nurses. These nurses might be used to the organisation of work-related vaccinations in their hospitals and therefore see fewer constraints in this respect. Third, anticipated negative affect regarding acceptance only appeared for midwives. This matches and is tentatively explained by our finding that midwives were more likely to have a specific philosophical background.
Determinants of attitude
The risk perception (or fear) for vaccination side effects and the perceived susceptibility to pertussis are frequently described regarding the acceptance of pertussis cocooning vaccination by HCWs (Peadon et al. 2007, Harrison et al. 2016, Paranthaman et al. 2016). This is in line with our study, where the aspects of risk perception showed a unique
