The Dynamics of Trust-Related Belief in Health Informatics: A Structural Equation Modeling of Health Information Adoption in Indonesia

Abstract

The rapid digitalization of health resources highlights the need to understand health information adoption in Indonesia. This study examines trust-related HBM belief pathways and Health Information Access Behavior (HIAB) as both a direct predictor and a moderator. Survey data from 260 respondents across urban, suburban, and rural settings were analyzed using PLS-SEM, with 20 semi-structured interviews used for interpretive context. Perceived benefits, cues to action, and self-efficacy significantly increased adoption, and HIAB had a significant positive direct effect. Moderation was limited: only the perceived barriers and HIAB interaction was significant and negative (β = −0.123, p = 0.023), while the other five interactions were not significant. Thus, access behavior does not uniformly strengthen trust-related HBM pathways; its moderating role is specific to perceived barriers.
