The influence of parents’ information processing on childhood vaccine acceptance after a vaccine crisis in China

Abstract

Drawing upon the protective action decision model and the heuristic-systematic model, this study investigated the determinants of parents’ response to the 2016 vaccine crisis in Shandong Province, China. A survey was conducted from Anhui Province (N = 456). The findings showed that both perceived vaccine knowledge and perceptions of risk from the vaccine crisis were vital in predicting parents’ information insufficiency (the perceived discrepancy between actual and desired levels of vaccine knowledge), information seeking, information processing (where parents make a judgement about information validity), and their intentions towards childhood vaccination. In addition, information insufficiency and information seeking also significantly facilitated parents’ information processing. When parents described processing information systematically, they were more likely to accept childhood vaccination. On the other hand, seeking more information about the crisis did not influence reported childhood vaccination practices. Implications and suggestions for health-related crisis communication research are discussed.
