Knowledge, attitude, and practice (KAP) survey data are vital to help plan, implement, and evaluate prevention and control work and have been the leading educational intervention strategy for respiratory disease control across the globe. This study was conducted to determine the validity of the KAP questionnaire on TB through exploratory factor analysis among professional nurses in Libya. A cross-sectional design using a self-administered prepared TB-KAP questionnaire was conducted to explore the validity. A total of 384 questionnaires were distributed to nurses in tuberculosis centres in Libya. The results of exploratory factor analysis revealed that 109 (97.3%) out of the 112 items were acceptable. Kaiser-Meyer-Olkin (KMO) measures of sampling adequacy was 0.85, 0.77, 071 and Bartlett’s test of sphericity was significant (c2= 21400.87), (p < 0.05), (c2 = 713.73), p <0.05), (c2 = 2673.32, p < 0.05) for knowledge, attitude, and practice, respectively. The questionnaire on TB knowledge, attitudes, and practices was valid and reliable, with good items that enable its use to assess the TB–KAP survey among TB nurses.
