Development of a Mobile Application Called TansiyoRitim for Hypertension Patients

Demographic Information Form

This form, developed as a result of a literature review, contains 19 questions. Before the mobile application is launched, this form will be used to collect patients' sociodemographic data.

Blood Pressure Measurement and Monitoring Form

All blood pressure measurements will be taken by the researcher using a calibrated mercury manometer (blood pressure monitor). The first measurement will be taken from both arms. If a difference of more than 10 mmHg is recorded between the arms, then all subsequent blood pressure measurements will be taken from the arm with the higher blood pressure reading. The average of the three blood pressure measurements taken from the identified arm will then be used for evaluation. Patients' blood pressure values will be measured every two weeks for three months starting from the beginning of using the mobile application, and recorded in the relevant form logbook for evaluation.

Hill-Bone Hypertension Treatment Adherence Scale (HBHTTUÖ)

The Cronbach's alpha value of the scale was determined to be 0.83. The scale consists of a total of 14 questions using a 4-point Likert scale. Answers are scored as (1) "Never", (2) "Sometimes", (3) "Most of the time" and (4) "Always". All questions except question 6 are negative questions. The scale consists of appointment, medical and nutritional subscales in addition to the total score. The overall score of the scale ranges from 0 to 42. When a patient answers all questions positively and receives a score of "0", they are considered fully compliant. The lower the score, the higher the compliance. After obtaining informed consent from the participants, the relevant scale will be administered as a pre-test. Once the mobile application usage process is complete, the same scale will be repeated as a post-test in the third month of the application.

Hypertension Self-Efficacy Scale

The scale consists of 20 items. The original scale uses a 4-point Likert scale, with each item ranging from "not at all appropriate" (1 point) to "very appropriate" (4 points). Items are scored between 1 and 4 points. A total score of 20 to 80 points is obtained from the scale. A higher total score indicates a higher level of self-efficacy in hypertension. The Cronbach's alpha reliability coefficient of the scale was found to be 0.78. After obtaining informed consent from the participants, the relevant scale will be administered as a pre-test. Once the mobile application usage process is complete, the same scale will be repeated as a post-test in the third month of the application.

Mobile Application Usability Scale

The scale is a 7-point Likert type scale, consisting of 10 factors, each with 4 items, for a total of 40 items. As the score obtained from the scale increases, usability also increases. In the study, it was determined that the Cronbach alpha coefficient values ranged from 0.74 to 0.94.

DISCERN (Quality Criteria for Consumer Health Information)

The DISCERN scale was developed to evaluate the quality of educational materials designed to inform individuals about health and treatment options. Each question is scaled from 1 to 5 points, from Yes to No. A definite yes answer receives 5 points, while a definite no answer receives 1 point. The total number of responses is used to obtain a DISCERN score ranging from 15 to 75, with scores between 16 and 26 classified as very inadequate. Item 16, which provides the overall assessment, is further evaluated as follows: 63-75 points excellent, 51-62 points good, 39-50 points average, and 27-38 points inadequate. The quality and reliability of training materials will be evaluated by experts using a standardized scale at baseline, before integration into the mobile application. Higher scores indicate better quality and reliability.
