In smoking cessation programs, identifying and monitoring patients' symptoms, including cravings, is essential. The widely used questionnaire for assessing craving symptoms is the QSU-B questionnaire. However, there has been no Indonesian translation of the QSU-B questionnaire to date. This study aimed to translate and assess the validity and reliability of the QSU-B questionnaire in Indonesian. This was a cross-sectional study involving in-depth interview with five expert panels and filling out a questionnaire by102 smokers. The translation was conducted independently by a certified translator. Validity was assessed using the Item-Level Content Validity Index (I-CVI), Scale-Level Content Validity Index (S-CVI), and correlation tests. Internal consistency reliability was measured using Cronbach's alpha. The QSU-B questionnaire, translated by an independent translator, was retranslated into English, and discussed by experts in a panel. The final questionnaire formulation was then used for further testing. Content validity assessment found that the QSU-B questionnaire was valid with I-CVI scores of 0.9-1 and S-SCVI of 0.98. Construct validity assessment found that the questionnaire was valid, with correlation values greater than the referral value. Reliability testing results showed that the QSU-B questionnaire was reliable, with a Cronbach's alpha value of 0.954. The Indonesian version of the QSU-B questionnaire was found to be valid and reliable, making it suitable for clinical use in patient management.
