Determinants of satisfaction with information and additional information-seeking behaviour for the pertussis vaccination given during pregnancy

Objectives: Information search and processing is critical to the vaccine decision-making process. However, the role of drivers of information satisfaction and search is not fully understood. Here, we investigated the predictive potential of psychosocial characteristics related to satisfaction with information and additional information-seeking about the pertussis vaccine currently recommended during pregnancy. Design: Cross-sectional online questionnaire study. Methods: A UK based sample of 314 women who had given birth during the previous six months was recruited to participate. The questionnaire included measures of the psycho-social predictors: trust, coping strategies, attitude towards vaccine information-seeking behaviour and risk perception of vaccination during pregnancy, and measures of two outcome variables: satisfaction with information received from a health care professional and whether participants engaged in vaccine information-seeking behaviour. Results: Trust in health care professionals, a perceived behavioural control of own vaccine information-seeking behaviour, and an engaged problem-focused strategy for coping with stress were significant predictors of satisfaction with official information given by a health care professional. 40% of women sought out additional information about vaccination however, none of the psychosocial factors measured significantly predicted the behaviour. Conclusions: We found that high trust in health care professionals, a perceived ability to seek out accurate information about vaccines and actively focusing on problems as a means of coping with stress, drives satisfaction in official vaccine information. We also developed measures of these variables that could be used in further research.
