The intervention group participants filled out all the data collection tools in the first interview and three months later. They received modular training by phone 2 weeks, 4 weeks, 8 weeks, and 12 weeks after the first interview.

The control group participants filled out all the data collection tools in the first interview and three months later. They did not receive any modular training.

The intervention group participants filled out all the data collection tools in the first interview and three months later. They received modular training by phone 2 weeks, 4 weeks, 8 weeks, and 12 weeks after the first interview.The modular training addressed (1) defining hypertension, (2) systemic effects of hypertension, (3) general effects of antihypertension drugs, (4) regular medication and blood pressure monitoring, and (5) eating a healthy diet and being active (what to do for a better heart health and a more stable blood pressure)

It is expected that the pre-training self-efficacy scale score averages of the patients in the intervention group will increase after the training. For this purpose, the Hypertension Self-efficacy Scale was used. Self-Efficacy Scale in Hypertension was used to determine the self-efficacy levels of patients diagnosed with hypertension. The scale consists of 20 items. The items of the scale are in the 4-point Likert type, ranging from "not at all appropriate" (1 point) to "very appropriate" (4 points). The total score of the scale varies between 20-80 points. An increase in the total score obtained from the scale indicates an increase in the level of self-efficacy in hypertension.

It is aimed that the average score of the patients in the intervention group on the chronic disease adaptation scale before the training will increase after the training.For this purpose, the chronic disease adjustment scale was used.The Scale of Adjustment in Chronic Diseases is a 5-point Likert type and consists of 25 items and three sub-dimensions: physical adjustment, social adjustment and psychological adjustment. The scale ranges from 1 (strongly disagree) to 5 (strongly agree). Negative items are reverse scored. The highest score is 125. An increase in the score obtained from the scale indicates a high level of patient adjustment to the disease.

The Turkish Modified Morisky Scale was used to test this. The Turkish Modified Morisky Scale is a reliable, easy-to-apply scale consisting of six questions that can separately evaluate the knowledge and motivation levels regarding drug use habits. In the evaluation of the answers given as "Yes" or "No"; the yes answer to the 2nd and 5th questions was calculated as 1 point, the no answer as 0 points; and the yes answer to the other questions was calculated as 0 points, the no answer as 1 point. The total score received by the patient from the 1st, 2nd and 6th questions; 0 or 1 indicates a low motivation level, while values above 1 indicate a high motivation level. The total score received from the 3rd, 4th and 5th questions; 0 or 1 indicates a low knowledge level, and values above 1 indicate a high knowledge level.
