This study aims to determine the influence of the constructs of the health belief model and fear of dementia on the behavioral intention to prevent middle-aged Korean adults' dementia. Applying a descriptive design, 163 middle-aged adults were recruited. Structured questionnaires were used to collect data regarding fear of dementia, behavioral intention to prevent dementia, the expanded health belief model's variables (i.e., perceived susceptibility, perceived severity, perceived benefit, perceived barrier, cues to action, general health motivation, and self-efficacy), and other general characteristics between August and September 2019. The determinants of the behavioral intention for dementia prevention were identified through hierarchical regression analysis. The significant factors influencing the behavioral intention for dementia prevention were general health motivation and self-efficacy, accounting for 34.2% of the variance. The results revealed key factors that should be considered in future interventions to enhance adherence concerning dementia-preventive behaviors.
