Development of Knowledge, Attitude and Practice Questionnaire for Patients with Diabetes Mellitus

Diabetes is one of the most common chronic diseases worldwide. The number of people with type 2 diabetes began to rise globally in the 1990 s, and since 2000, the world has seen a dramatic increase. There is a need to assess Knowledge, Attitude and Practice (KAP) of patients with diabetes in order to aid in future development of control programs and techniques for effective health education and patients counselling. this study was intended to develop a KAP questionnaire. It is a 27-question closed ended questionnaire with 12 knowledge, 8 attitude and 7 practice questions. Each correct answer was given a score 1 and the incorrect answer was given 0. Total scores of Knowledges, Attitude and Practice were added together to yield the final KAP score, where 25 was the highest and 0 was the least KAP score a subject could get. The questionnaire was reviewed by doctors and fellow pharmacists. Reliability of the questionnaire was calculated using “Kuder Richardson 21 (KR21)” method using a sample data of KAP score from 20 patients. After applying the formula, the scores obtained for Knowledge, Attitude, Practice and KAP were 0.71, 0.80, 0.71, and 0.75 respectively. The results show that the questionnaire is a valid instrument that allows an assessment of knowledge, attitudes and practices levels of patients with diabetes mellitus
