Objectives The purpose of the current study was to examine the reliability of answers to some question items of K-prism using a test-retest approach.
Methods We surveyed K-prism twice times at the interval of 6 months. We analyzed the reliability of test-retest for 55 items
by performing McNemar analysis.
Results As a result of the research on 55 items, 38 items showed an agreement of 80% or more and significant changes were shown in 6 items(P<0.05). There was a significant change in the answer on items No.4-3. 5-3, 11-3, 12-1(in the item of personality) and items No.20-3,4, 27-2(in the item of pathophysiological symptom(素證)). Among the personality items, the 'medium' response type affected the items showing significant response changes.
Conclusion Through this study, most of the items of the k-prism questionnaire were reliable in test-retest. It may be necessary to consider revising the content and format for certain questions.
