Evaluating the Effect of Using Training CDs on the Patients with Type II Diabetes

With a variety of short-term and long-term complications, diabetes is one of the most common diseases in the world and has negative effects on different body systems (e.g., brain, heart, kidneys) (1). The prevalence of diabetes is high in Iran and one per 20 of the Iranian people suffers from diabetes. However, the most important problem is that most people do not know they are sick and this causes irreparable consequences (1). Although diabetes is a common disease, some provisions can be thought to prevent its progress and in some cases prevent its occurrence. One of these cases is training diabetic patients. Training can be done through different ways such as using pamphlets, leaflets, photographs, videos, and training classes about the disease for patients. With regard to the evolution of technology and new instruments, better and more effective methods are implemented for training in the world (2, 3). In this study, patients with diabetes were trained through instructional videos. First, patients with type II diabetes referred to the clinic were identified. Then, the date and time of their next visit to the clinic were arranged. Moreover, the objectives of the study were explained to the participants. The samples were divided into two groups: case and control groups. Initially, the two groups were given a test battery including demographic information (i.e., age, gender, height, weight, marital status, location, and history of disease) and 10 questions on their knowledge and attitudes about diabetes, in which the 5-point Likert-type scale was used (Completely know = 5, Partly know = 4, Not sure = 3, Slightly know = 2, and Do not know = 1). Overall, the total score of the questionnaire was 50 points and it was classified into four categories including the low score category (1020 points), the lower-middle score category (21-30 points), the upper-middle score category (31-40 points), and high score category (41-50 points). The sample size based on the following statistical formula was at least 44 patients in each group:
