Adherence to treatment
Modanloo’s Chronic Patients Adherence Questionnaire was used to assess adherence to the treatment of heart patients in various dimensions (acceptance of medication, diet, weight control, physical activity, follow-up time for treatment, and lifestyle changes). This scale has 40 items in the form of 7 subscales in the areas of concern in treatment (9 questions), willingness to participate in treatment (7 questions), ability to adapt (7 questions), integration of treatment with life (5 questions), adherence to treatment (4 questions), commitment to treatment (5 questions), and management of treatment (3 questions). This questionnaire is scored based on 5-point Likert scale (strongly agree = 1, disagree = 2, neutral = 3, agree = 4, strongly agree = 5). The higher the total score or the score of each subscale, the higher the adherence of the respondent. In Modanloo’s study, the correlation coefficient test-retest was reported 0.87. The internal consistency was Cronbach’s alpha = 0.92 [
