- Purpose
The purpose of this study was to identify the factors influencing dementia preventive behaviors of older adults at high risk of dementia based on extended health belief model.
Methods
The subjects were 140 older adults at high risk of dementia living in H-gun, Gyeongsangnam-do, Republic of Korea. The data was collected from April 21 to May 28, 2021 by using structured questionnaires. The data was analyzed using t-test, ANOVA, Scheffé test, Pearson’s correlation coefficient, and hierarchical multiple regression by SPSS/WIN 24.0 program.
Results
The mean score of dementia preventive behaviors of older adults at high risk of dementia was 3.47±0.49 (range 1-5). The factors influencing dementia preventive behaviors were self-efficacy (β=.82, p<.001), cues to action(β=.17, p=.013), ages 75-79 (β=0.35, p=.003; reference: ages 65-69), ages ≥80 (β=0.27, p=.021; reference: ages 65-69), which together explained 82.0% of total variance in dementia preventive behaviors (F=25.21, p<.001).
Conclusion
Based on the results of this study, it is highly recommended to develop and apply the dementia prevention program that can increase self-efficacy and cues to action for improving dementia preventive behavior of older adults at high risk of dementia.
