This work aims to analyse the impact of pre-illness behaviour, knowledge, self-efficacy, family support and the environment on tuberculosis prevention behaviour in the context of Surabaya, Indonesia. This cross-sectional research comprises 176 respondents over 17 years of age, who were selected by simple random sampling. Data collection was carried out to assess behavioural data before illness, knowledge, self-efficacy, family and environmental support for tuberculosis transmission prevention behaviour. The data were used todetermine the predictive factors that influenced the behaviour of the prevention of tuberculosis transmission by using multiple linear regression. The level of significance was set at P <0.05. The results of multiple linear regression demonstrated that family support, self-efficacy and behaviour before illness had more influence on tuberculosis transmission prevention behaviour. More specifically,Y = 20.314 + (0.359) X1 + 0.241X2 + 0.225X3 + 0.855X4 + 0.462X5, where Y = tuberculosis transmission prevention behaviour, 20.314 = coefficient value, X1 (0.359) = behaviour before illness, X2 (0.241) = knowledge, X3 (0.225) = self-efficacy, X4 (0.855) = family support and X5 (0.462) = environmental factor. The preventing tuberculosis transmission behaviour in Surabaya, Indonesia was more influenced by family support factors, self-efficacy, and pre-illness behaviour. Therefore, the standard for preventing tuberculosis transmission in the family was prioritized in reducing the spread of tuberculosis.
