Εhealth Literacy, Beliefs About Medication and Adherence in Older Adults with Chronic Diseases: A Cross-sectional Study
摘要
eHealth literacy can enhance behavioral change in health, beliefs, and medication adherence behaviors, or not, in people with chronic diseases. The current study aimed to investigate the effect of eHealth literacy as well as medication beliefs on medication adherence in older people with chronic diseases. A convenient sample of 200 recipients of Primary Health Care (PHC) services with chronic diseases was administered a sociodemographic and clinical characteristics questionnaire, the eHEALS scale, the Morisky Green Levin Adherence Scale (MAQ), and the BMQ scale. The total rate of low and moderate adherence ranged at 58.8% and concerned the majority of older people whose mean age was 68 years. The average score for eHealth literacy was 19.5 points (SD = 9.8 points). High scores were noted in all dimensions of BMQ. People with high medication adherence (41.2%) showed a lower score in the dimensions of “concern”, “abuse”, and “harmful consequences” (p < 0.001), while they showed a high score in eHealth literacy (p = 0.005). The more they feared the harmful effects of the medication, the less likely they were to have high adherence [OR (95% CI) 0.83 (0.75–0.93), P = 0.001]. The present study highlighted the importance of ehealth literacy for beliefs and medication adherence. Policy makers need to transform public health systems and provide older adults with sufficient knowledge and skills in eHealth literacy so as to promote adherence and increase clinical benefit.
