Stratified sampling technique was used to select 217 respondents who attended hypertension clinic at Kade Government Hospital in the Kwaebibirem Municipality from January to April 2023.

Paired T-tests and McNemar-Bowker for dependent samples were performed to compare the participants’ levels of knowledge about hypertension and its therapy, beliefs about medicines, and levels of adherence to antihypertensive therapy before and after the educational intervention. There was significant increase in the patients’ levels of knowledge about hypertension (P<.001), beliefs about medicines were significantly modified in a positive manner (P<.001), and a significant (p<0.001) difference in adherence scores before and after the educational intervention. The results of this study indicate a deliberate educational intervention has a positive effect on knowledge, belief and adherence.
