Abstract

Background: In advanced cancer patients, pain is one of the most common symptoms and requires long-term opioid therapy. Patients should have adequate knowledge and adhere to opioid treatment to achieve the desired effect. Objective: To develop and validate a knowledge, attitude and practice (KAP) questionnaire on opioid use in cancer outpatients. Methods: The study was conducted through 5 phases: (1) Conduct a preliminary questionaire based on literature review, of relevant national and international studies; (2) Review and revise the questionnaire based on feedbacks from expert panel; (3) Determine the level of clarity and intelligibility of the questionnaire in 10 patients; (4) Assess the internal consistency of the questionnaire based on a pilot of 20 patients. Cronbach's alpha of at least 0.7 indicated adequate internal consistency. Content validity was based on the expert judgment at the second time; (5) Complete the questionnaire. Results: In terms of content, all items received full score at the second judgment by the expert panel. The mean score for semantic and idiomatic compatibility was 0.96 ± 0.05. Cronbach's alpha values of all items in the questionnaire were over 0.7. Conclusions: The KAP questionnaire on opioid use was developed and achieved its internal consitency and content validity to use for survey on opioid use in outpatient settings.
