Abstract

Non-adherence to the treatment of chronic diseases such as hypertension and Diabetes Mellitus (DM) is a major obstacle in achieving patient therapy targets and quality of life of patients. A comprehensive approach involving pharmacists counselling has shown influences on changes in health behaviour and patient compliance. Behaviour changes in patients are one of the parameters to assess the effectiveness of counselling and education by pharmacists. Therefore, it is necessary to develop questionnaires of behaviour change measurement in DM-hypertension patients. This study aims to develop a measurement instrument in the form of questionnaires in assessing the behaviour change of DM-hypertension patients. Preparation of question items from the questionnaire research instrument refers to some guidelines and previous research references. Test of questionnaire instrument valid was done with expert validation, followed by pilot testing on 10 healthy respondents, and 10 DM-hypertension patients included in the inclusion criteria. Furthermore, field validation test was conducted on 37 patients who had undergone outpatient care at the PKU Muhammadiyah Yogyakarta City Hospital and The Gading Clinic in Yogyakarta. The inclusion criteria were male and female patients, aged 18-65, diagnosed with type 2 diabetes with hypertension who received oral antidiabetic drugs and antihypertensives, and who were not illiterate and co-operative. The data were collected by questionnaire interviews by a standardized pharmacist. The result of validation test using Person correlation shows the value of 0.33. The results of the questionnaire validation test on 37 patients showed 5 items of invalid questions with the value of r <0.33, e: questions 2, 3, 6, 10 and 11, while the other 10 questions show the value of Pearson correlation > 0.33. The reliability value is shown from the Cronbach's alpha value of 0.722 (> 0.6), implying that the questionnaire is reliable for DM-hypertension patients. This Behavioural change questionnaire can be used on DM-hypertension patients, and an FGD approach is required for the development of factors affecting this questionnaire.
