SUMMARY
The irrational and incompliance use of antibiotics has been correlated to bacterial resistance. Several methods evaluated patients' compliance with oral antibiotics have been conducted. However, a standard questionnaire for evaluating oral antibiotics compliance in Indonesian has not been developed yet. This study was conducted to record the content validity of the developed questionnaire called 20-KAO to assess compliance with oral antibiotics. The validity content test was conducted through six experts review using the Item Content Validity Index (I-CVI) and Scale-Content Validity Index (S-CVI). The experts were also requested to provide recommendations for each item, whether revisions or deletion. After the review process, the number of questions remains unchanged. A total of 19 out of 20 items had an I-CVI of 1.00, and S-CVI was calculated at 0.98. Therefore, 20 items of the 20-KAO questionnaire have excellent content validity. However, future construct validity and reliability test to analyze the responses of targeted respondents and the questionnaire's consistency are needed.
