The Delphi technique is a widely used and accepted method to obtain consensus among the
experts. This technique uses a judgement to prove the accuracy of the content item when evaluating
instrument. The objective of this study is to discuss the process of the three rounds Delphi technique
to obtain consensus of concept mapping care plan and multiple choice questions (MCQ) in Diabetic
Mellitus subject. In the first round, participants were given a structured questionnaire regarding item
of concept mapping care plan and MCQ in Diabetic Mellitus subject. In the second round, the mean
and median values of round one were added. In the third round, the mean and median values of round
two were added. Participants were asked to rate the categorised responses from Round 1 on a scale of
1 to 5, with 1 being “Very Irrelevant” and 5 being “Very Relevant”. This technique does not require
that participants be collocated or meet face-to-face, thereby making it useful to conduct surveys
with qualified people over a wide geographic area. The feedback process allows and encourages the
selected Delphi participants to reassess their initial judgements about the information provided in
previous iterations. The analysis of consensus data of the experts was done based on median, inter
quartile range and quartile deviation on round one, two and three data. The median score was used to
analyse the level of consensus of experts and result shows that in all three rounds Delphi the medium
result more than 4. It reported that level of importance of the statements were high. As a conclusion,
the concept mapping care plan and MCQ have meets the consensus by using three rounds of Delphi
techniques. Therefore, the Delphi technique is the best method to obtain consensus in health care
education research.
