THE EFFECT OF AN EDUCATIONAL INTERVENTION ON THE MEDICATION ADHERENCE IN PATIENTS WITH HYPERTENSION: BASED ON BASNEF MODEL

Hypertension is a major public health issue. Lack of medication adherence in
patients with hypertension can lead to adverse outcomes. Therefore, patients need to be educated on
how to control their blood pressure and increase their behavioral preventive skills. Among the numerous
models of health education, BASNEF model is the most comprehensive model used to study, identify
and create new behaviors. This study aimed to determine the effect of an educational intervention based
on BASNEF model on the medication adherence in patients with hypertension.
Materials & Methods: This quasi-experimental study with pretest-posttest design conducted on 80
patients with hypertension referred to Health Centers in Urmia, Iran, and met the eligibility criteria.
They were selected using convenience sampling method and then, randomly assigned to two groups as
control and experimental. A 4-part questionnaire was used for collecting the data. The collected data
was analyzed by SPSS v.16 software using descriptive and inferential statistics (independent t-test,
Mann-Whitney U test and Chi-square test).
Results: The results showed that the mean score of medication adherence in patients with hypertension
in the experimental group was significantly more than the control group (P<0.001).
Conclusion: It seems that educational intervention based on BASNEF model has considerable
advantages and increases the medication adherence in patients with hypertension significantly.
Therefore, it is recommended to apply this educational model as a key complementary factor to increases
compliance of patients with hypertension
