The Effectiveness of Using a Mobile Application for Type 2 Diabetes Self-care

Self-care in individuals with type 2 diabetes will be assessed using the Self-Care of Diabetes Inventory (SCODI) questionnaire from Ausili et al., 2017. The tool consists of 40 assumptions classified into four dimensions: self-care maintenance (12 assumptions), self-care implementation (8 assumptions), self-care monitoring (9 assumptions), and self-confidence (11 assumptions). The instrument is assessed using the Likert scale, where a higher score represents better self-care. Change in SCODI score will be assessed at the enrolment of the patient followed by the examination in the period of up to 6 months after the enrolment.

The investigators will use the "Brief Illness Perception Questionnaire" (Brief IPQ) to assess disease perception from authors Broadbent, et al., 2006. The questionnaire provides a rapid assessment of disease perception and measures the patient's cognitive and emotional representations of their disease. The questionnaire contains eight graded questions on a 10-point scale and one open-ended question. The higher the score, the more threatening the individual's view of the disease. Change in Brief IPQ score will be assessed at the enrolment of the patient followed by the examination in the period of up to 6 months after the enrolment.

The investigators will assess the frequency of use at the first check-up for individuals who will use the application during the research. The questions were partially summarized after the "Video Games Preference Inventory" survey questionnaire from authors Kenny & McDaniel, 2011. In its primary form, the survey questionnaire consists of ten questions. The investigators summarized the first five questions for our research, which the investigators also adapted according to the research content. The questions are rated on the Likert scale (1 = Strongly disagree; 2 = Disagree; 3 = No opinion; 4 = Agree; 5 = Strongly agree). The higher the average rating the user receives, the higher the mobile application level. Frequency of the mobile application use will be collected at the examination in the period of up to 6 months after the enrolment.

The registered nurse will measure the patient's body weight with the help of a calibrated technique before the start of the research and at the first examination. The investigators are interested in whether the use of the mobile application will have an effect on weight loss.

The registered nurse will measure the patient's glycated hemoglobin with the help of a calibrated glycated hemoglobin monitor before the start of the research and at the first check-up. The investigators will be able to see if the glycated hemoglobin level has decreased in the time before the examination until the first examination. Recommended target HbA1c is less than 7%.

The registered nurse will measure the patient's blood sugar with the help of a calibrated blood sugar monitor before the start of the research and at the first check-up. The investigators will be able to see if the blood sugar level has decreased in the time before the examination until the first examination.

The registered nurse will measure the patient's blood pressure with the help of a calibrated blood pressure monitor before the start of the research and at the first check-up. Based on the American Heart Association, these values can be divided into categories (Normal = systolic less than 120, and diastolic less than 80; elevated = systolic between 120 and 129, and diastolic less than 80; hypertension stage 1 = systolic between 130, and 139, or diastolic between 80, and 89; hypertension stage 2 = systolic 140 or higher, or diastolic 90 or higher; hypertension stage 3 = systolic higher than 180, and/or diastolic higher than 120).
