The alleviation effect of knowledge integration on anxiety in parental vaccine decision-making supported by online communities

Abstract

\nPurpose\nTo support vaccine decision-making, a growing number of parents use online communities to obtain informational and emotional support; however, relatively high information heterogeneity and polarization in the online environment make it challenging for parents to make informed vaccine decisions based on the systematic processing of conflicting information. In this context, this study aims to focus on the relationship between parents’ knowledge integration and rational and experiential decision-making and the mediating effect of anxiety on this relationship.\n\n\nDesign/methodology/approach\nA theoretical model incorporating the direct and indirect effects of knowledge integration and anxiety on decision-making is proposed and tested through partial least squares structural equation modeling with survey data from 223 parents.\n\n\nFindings\nKnowledge integration negatively affects anxiety. Knowledge integration has a direct positive effect on rational decision-making and an indirect negative effect on experiential decision-making.\n\n\nPractical implications\nThese insights into the key role of knowledge integration in parental vaccine decision-making under information heterogeneity and polarization provide support for practical strategies to encourage knowledge integration and alleviate anxiety in online communities.\n\n\nOriginality/value\nThis study underscores the importance of knowledge integration in vaccine decision-making under information heterogeneity and polarization and reveals distinct mechanisms underlying the effects of knowledge integration on decision-making dominated by rational and experiential modes. The findings also provide insights into the information processing mechanisms underlying the knowledge integration of subjects with insufficient prior knowledge in the non-organizational context.\n
