Abstract
Purpose – The purpose of this study is to evaluate the factors that influence saftey behaviourial intention (SBI) of construction workers. While SBI has been identified as the most proximal cause of unsafe behaviour, few studies have modelled the dynamic relationships of factors influencing it. Moreover, the few studies that have modelled the relationship have, in most cases, provided ambiguous results with varying levels of consistency. Design/methodology/approach – Using a semi-structured questionnaire, this study adopted a fuzzy synthesis evaluation (FSE) approach based on quantitative data from 562 construction workers across Nigeria. Findings – Results from the FSE show that 25 out of 35 factors identified from previous studies were critical. The FSE analysis yielded an overall SBI index of 3.52, emphasising the critical nature of these factors. In addition, the study yielded an empirical principal categorisation of SBI factors into "safety knowledge", "work experience", "perceived behaviour", safety attitude", "safety compliance", "safety participation" and "safety motivation". Practical implications – This study underscores the factors that influence SBI of construction workers, emphasising the need to foster a safety-first culture by encouraging active worker involvement in safety efforts that include hazard identification and mitigation. Originality/value – Adopting a fuzzy methodological approach, findings from this study contribute to comprehending the influence of individual safety dynamics of construction workers, towards a holistic lens through which safety behaviour dynamics of construction workers could be better established.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
