- The standard choice-based data will be used to assess the quality of the model fitted using the adaptive data. It will also be used for a qualitative comparison of adaptive (ACBC) and standard (CBC) data collection using descriptive approach.
研究概览
简要总结
This study aims to establish an effective method to inform parents or close relatives of newborns about the risk of pertussis transmission to newborns and the advantages offered by the cocooning strategy (vaccinating those who are in close contact with the newborn) by assessing the factors that affect the parents' decision-making to accept pertussis immunisation.
详细描述
Two phases are foreseen in the study. The 'questionnaire design' phase will be conducted in order to finalise the electronic questionnaire. The enrollment phase will involve the administration of the final web-based questionnaires to the subjects included in the enrollment phase.
The data generated in this study will be useful to inform parents of newborns about the advantages of vaccinating people who are in close contact with the newborn even before the baby is born in order to prevent the transmission of pertussis to the newborn.
No vaccine will be administered during this study.

结局指标
主要结局
The standard choice-based data will be used to assess the quality of the model fitted using the adaptive data. It will also be used for a qualitative comparison of adaptive (ACBC) and standard (CBC) data collection using descriptive approach.
时间窗: After completion of the questionnaire by all the subjects (Visit 1 i.e. Day 0).
The primary endpoint constitutes the answers collected from all conjoint sections of the adaptive web-based questionnaire.
次要结局
- The secondary endpoints constitute in all, the non-conjoint ancillary data collected through the web-based fixed questionnaire including, but not limited to: gender, age, family composition, education level and ethnicity.(After completion of the questionnaire by all the subjects (Visit 1 i.e. Day 0).)
