In November 2012, we asked the medical advisors of the five NIP coordination regions in the Netherlands to invite organisations in their region that carry out child welfare services to participate in the study. Eight organisations that were dispersed over three of the five coordination regions cooperated. In total, these organisations received 900 sets of questionnaires for dissemination among their Child Welfare Centres (CWCs) in December 2012. These CWCs asked their personnel to further distribute them among the target group. In the research period, most CWCs handed the questionnaires to all parents during their first well-visit at the centre, four weeks postpartum. One CWC arranged for the parents to receive the questionnaires in the first week postpartum, through healthcare workers visiting at home for the infants’ newborn screening. Along with the questionnaire all parents received a leaflet with information regarding the purpose of the study, and a short introduction to the pertussis cocooning strategy comparable to regular public health information provided in the NIP. In the letter it was also made clear that completing the questionnaire was voluntary, had no consequences regarding the care of the CWC, and that consent was implied by questionnaire completion.
