ABSTRACT
Introduction: Tuberculosis (TB) is still a persistent health challenge in Indonesia and ranks high on the list of factors causing morbidity and mortality. Improving knowledge, attitudes, and perceptions (KAP) of the general community about TB can help to control the disease. Purpose: This study aimed to examine the KAP about TB in Indonesian society and investigate their sociodemographic determinants. Participants and Methods: An online cross-sectional survey in 34 provinces in Indonesia was carried out in June 2022. The scores of KAP were classified as low, moderate, and high. Bivariate and multivariate ordinal logistic regression were applied to identify the potential sociodemographic determinants of KAP. Adjusted odds ratio and 95% confidence interval (CI) for each determinant were provided. Results: Among the 3205 participants, 56.4%, 91%, and 38% had high scores on knowledge, attitude, and perception, respectively. Independent determinants of high knowledge were age (26-35 years; adjusted odds ratio: 1.53 [95% CI: 1.19-1.97]), marital status (married; adjusted odds ratio: 1.18 [95% CI: 1.00-1.39]), and salary (middle income; adjusted odds ratio: 0.76 [95% CI: 0.63-0.93]). Independent factors associated with high scores in attitude and perception were the residence location (village; adjusted odds ratio: 0.76 [95% CI: 0.59-0.98]) and the occupation type (civil servant; adjusted odds ratio: 1.53 [95% CI: 1.09-2.13]), respectively. Conclusion: Most Indonesians have a high knowledge and good attitude, although they have a moderate perception toward TB. Improving public awareness and health education with the right strategies is critical to reducing the country's TB burden.
ABSTRACT
OBJECTIVE: This study aims to validate and evaluate the psychometric properties of the knowledge about tuberculosis questionnaire (KATUB-Q) for the general population in Indonesia. METHODS: The KATUB-Q consists of three domains: general knowledge, transmission, and treatment, with 20 dichotomous items. Rasch analysis through WINSTEPS was used. RESULTS: A total of 504 respondents from 34 provinces in Indonesia completed the survey. Based on the model fit statistics, 3 misfit items were deleted and 17 items were used. Item and person reliability, as well as Cronbach's Alpha values were 0.99, 0.63, and 0.73, respectively, which means they achieved the minimum acceptable limit of 0.6. Based on the results, Indonesia's Person ability analysis indicated a high level of knowledge. KATUB-Q has no significant bias item based on sex found in the differential item functioning analysis. CONCLUSION: KATUB-Q has 17 items with a valid and reliable instrument; hence, it can be used to measure the knowledge about TB in the general population. PRACTICE IMPLICATIONS: The unidimensional structure of the core items of the KATUB-Q provides empirical evidence for using the sum score of the items in practice to evaluate the effectiveness of TB education in the general population.
