Abstract
BackgroundTo prevent or recover from a disease, the prescriptions for medications must be correct, and the patient must comply with the medication’s instructions. Therefore, this study verified the theory of planned behavior (TPB) model to predict medication adherence among Korean adults and examined the role of optimistic or present bias in that model.MethodsThe participants were 357 Korean male and female adults whose ages ranged from 18 to 76 (M = 41.53, SD = 9.89). Their medication adherence was measured with the Morisky Green Levine Scale. The study examined TPB factors with modified items related to medication adherence and optimistic bias with items developed based on the concept and on previous studies.ResultsAn alternative TPB model, including a direct path from attitude to behavior, a direct path from the perceived behavioral control to the behavior, and an insignificant path from behavioral intention to behavior, was validated for Korean adults’ medication adherence. This model was found to be moderated by optimistic or present bias.ConclusionsThe findings of this study should provide useful information for future research and for medical or health professionals who wish to improve the medication adherence of their patients.
Highlights
To prevent or recover from a disease, the prescriptions for medications must be correct, and the patient must comply with the medication’s instructions
There was no significant correlation between optimistic bias and medication adherence (r = − 0.04, n.s.), though optimistic bias was negatively correlated with attitude (r = − 0.27, p < 0.001), subjective norms (r = − 0.12, p < 0.05), perceived behavioral control (r = − 0.24, p < 0.01), and behavioral intention of medication adherence (r = −.28, p < 0.001)
The present bias for medicinal effect was significantly correlated with the medication adherence (r = − 0.19, p < 0.001), but it was not significantly correlated with the theory of planned behavior (TPB) variables involved in medication adherence
Summary
To prevent or recover from a disease, the prescriptions for medications must be correct, and the patient must comply with the medication’s instructions. Koreans’ interest in health has been heightened in the twenty-first century as their living standards have improved and their life expectancy has increased significantly [1] Because of their high level of interest in health, it may seem likely that they intend to practice health behaviors to improve, maintain, or recover their health, but it is reported that they do not do so. Even when they have a prescription from a medical care provider or health professional, Koreans often do not, in actuality, adhere to the prescription instructions in practice.
