ABSTRACT
Village health workers (VHWs) play an essential role because they extend the capacity of primary healthcare, particularly for developing countries. In Lesotho, VHWs are part of the primary healthcare connecting the community with clinics in their respective villages. They contribute to the prevention of the spread of tuberculosis (TB) within their catchment areas by encouraging communities to partake in TB screening. This study aimed at identifying factors associated with the utilisation of VHWs' service to undertake TB screenings in Lesotho. Methods: This study emanates from the main study that used a cross-sectional descriptive design. A total of 19 health service areas (HSAs) comprised 17 catchment areas and two clinics, each randomly selected from the District Health Management Team (DHMT) and the Lesotho Flying Doctors Service (LFDS), respectively. A total of 2928 individual household members aged 15 and above were included in the study. Data analysis included descriptive and inferential statistics. Results: There were more female than male respondents, with a majority (77%) below 65 years of age. Tuberculosis knowledge of respondents was mostly on the TB symptoms and curability of TB, but they were less knowledgeable about the causes of TB. The use of VHWs' services for TB screening was very low (23.3%). Conclusion: The study revealed that while respondents were to some extent knowledgeable about TB, their utilisation of VHWs' services for TB screening varied with education level, having worked in South Africa and the household size at α = 0.01.

Background: A high level of awareness on tuberculosis (TB) is crucial for the success of the prevention and treatment among the high risk populations. Having a good perception about the treatment of TB may increase the acceptance of the control measures in decreasing the spread of the disease. Aims & Objective: To develop and validate a Questionnaire about the knowledge of the causes, mode of transmission, the prevention of TB and the perception of TB treatment among TB patients in Malaysia. Materials and Methods: A Cross-sectional study was conducted among TB patients attended the Respiratory Clinic at the Hospital Raja Perempuan Zainab II, Kelantan, Malaysia. This study used a self-administrated questionnaire that takes approximately 10 minutes to complete and was generally well received by the respondent’s. The validation involved content validity, exploratory factor analysis for the construct validity and internal consistency for reliability. Results: A total of seventy TB patients comprising of 39 males (55.7%) and 31 females (44.3%) responded. The Kaiser-Meyer-Olkin measure of sampling adequacy (KMO) was (0.827 and 0.723) and Bartlett's test of Sphericity was highly significant (P<0.001). The exploratory factor analysis was used with the extraction method of the principal component and the varimax rotation with normalization. The factor analysis showed six factors within the 28 items which were associated with TB knowledge, the cause and prevention, the mode of transmission and the perception of TB treatment. The internal consistency was [0.893, 0.552, 0.701 and 0.729] for the four factors of TB knowledge and [0.889 and, 0.697] 2 factors for the perception of TB treatment respectively. Conclusion: The questionnaire on TB knowledge, on the causes, the mode of transmission, and the prevention of TB and the perception of TB treatment was valid and reliable with good items that enables its use for assessing TB knowledge among TB patients and the community.
