Design outcomes

Primary

Measure	Time frame
The objective of the data gathered with this intervention is to compare the stated preferences (i.e. behaviour as reported in the Discrete choice experiment that was presented in the questionnaire phase of the research) with the actual behavior of the respondents when having to decide whether to vaccinate their child with the Hepatitis-B vaccin. First, the data from the questionaire will be used to predict to which extent respondents are likely to decide to vaccinate their child. For this, the data from the DCE will be combined with data from questions from the questionnaire, resulting in an estimation per parent on how likely they are to have their child vaccinated. The indepent parameters that contribute to the likelihood of vaccination will consist of (estimated) risk of becoming infected with Hepatitis B virus, (estimated) risk of side effects of vaccination, the manner of vaccination, information from formal sources, information from informal sources and behaviour of the peer group. The dependent variable will be the choice either or not to vaccinate, as expressed in the Discrete Choice Experiment. Subsequently, this predicition will be compared with the actual vaccination behavior of the parents when they are given the opportunity to vaccinate their child.	—

Secondary

Measure	Time frame
The parameters that contribute to agreement between stated preferences for hepatitis B vaccination and actual vaccination behaviour. These include attitude of the parents towards vaccination, knowledge on the disease concerned, (perceived) barriers to vaccination, opinions of friends and family towards vaccination. Data on these parameters have been collected during phase 1 of the research.	—
