Abstract
Methods The items for the new KAC-Q were developed based on the narrative literature review and focus group discussion. The Delphi Method was used to assess the content validity of the new KAC-Q. Fifteen experts were involved in three phases of the Delphi survey. The face validity was examined to ensure that the items in the questionnaire were understood by the targeted patients.
Results A total of 37 articles were found to be related to KAC. Almost 100 questions were compiled and categorized into nine domains. After three phases of the Delphi survey, 71 questions were deleted due to similar meaning, irrelevant and unsuitable to be used among the Malaysian population. Of the 29 questions retained, one question was deleted after the face validity test.
Conclusion The completeness and relevance of the KAC-Q as well as the meaning of each individual question were assessed through the content and face validity. With a good structured and adequate information, these 28 KAC-Q questions were considered to have good content and face validity. However, further psychometric testing is needed to ensure that KAC-Q is reliable and valid to aid health care providers in determining patients’ anticoagulant knowledge in targeted populations.
