Abstract: The construction sector experiences one of the highest workplace injury occurrences among all the other sectors in Singapore. For township workers, similarities to the job scope of construction workers can be drawn, and it can be inferred that they too face similar dangers. Moreover, safety problems involving township workers can easily be overlooked or undervalued due to the lack of accident or injury statistics for the industry. In efforts to minimize accident rates in all industries including construction and township management, the CultureSAFE programme was developed by the Workplace Safety Health Council (WSHC) to help organizations cultivate the right WSH culture via a series of assessments including a questionnaire. However, to date, there are no publicly available information on the validity of the questionnaire. This dissertation aims to evaluate the validity and reliability of the WSHC CultureSAFE questionnaire. Additionally, this study also aims to gather feedback from general workers regarding their perception towards the questionnaire for enhancement purposes. A comprehensive safety climate study can offer insightful underlying principles of the WSH in township management industry. The research was first conducted by reviewing literature of the township management industry, importance of safety climate in the industry, measurement of safety climate, WSHC CultureSAFE programme, as well as the exploring the difficulties in administering safety climate surveys. A total of 17 professionals were surveyed in the first phase to review the existing survey and the length of the questionnaire was shortened and studied via the use of Content Validity Ratio (CVR). After which, the finalized set of questionnaires was distributed to over 200 workers, and a final set of 151 responses were analysed after data cleansing. Analysis methods include Confirmatory Factor Analysis (CFA), Cronbach’s Alpha (α) and Split-half Reliability. Findings revealed that the originally theorised six-factor structure has poor model fit (i.e. poorly construct validity). Furthermore, it was also deduced that the one-factor structure can effectively capture most of the variables compared to an original six-factor structure established by WSHC. This could be due to the questions being designed in a manner where they revolve around the same single underlying principle. Moreover, there were also external factors that could influence the reliability of the results e.g. negatively-worded questions can result in wrong interpretation of the questions. In the overall context, this study creates opportunities to explore the applicability of the CultureSAFE questionnaire in the local township management industry and its safety quo in WSH.
