Purpose: This study was conducted to investigate factors affecting the dementia screening test based on the health belief model. Methods: The survey was conducted with structured questionnaires assessing the knowledge of dementia, health beliefs, self-efficacy and cue to action for dementia screening. Study participants were 156 older adults and data from 121 respondents were analyzed. Descriptive statistics, frequency percentage,
chi-squared (χ2) test, t-test and logistic regression analysis were conducted using SPSS version 23.0. Results: Factors influencing the dementia screening test were found to be gender, self-efficacy on dementia screening, and the presence of family or friends who underwent dementia screening. Older adults who were female (OR=4.92, p=.003), showed an increasing average score of self-efficacy for dementia screening (OR=2.85, p=.002), and
had family members or friends who underwent dementia screening (OR=4.60, p=.003) were more likely to receive dementia screening. Conclusion: This study showed that education and programs enhancing self-efficacy associated with the dementia screening test, as well as utilizing the network of family or friends are necessary to increase the rate of dementia screening.
