标题：Examining the Potential of Safety Knowledge as Extension Construct for Theory of Planned Behaviour: Explaining Safety Practices of Young Adults at Engineering Laboratories and Workshops
摘要：This study examined engineering student's self reported intention and behaviour in practising safety at workshops and laboratories by using the Theory of Planned Behaviour (TPB) with extension of Safety Knowledge as research framework. Eighty eight (n=88) participants from three engineering departments of a completed a survey questionnaire measuring their responses to five constructs of the framework. The multiple regressions results show that subjective norms were the most significant predictors of behavioural intention towards practising safety followed by perceived behavioural control and safety attitude. The second block of multiple regressions found that safety behaviour can be significantly explained by using the constructs of safety knowledge and behavioural intention. Overall, this study has shown that three explanatory variables in the TPB can explain behavioural intention of practising safety with 52% of variance and safety knowledge as an extension construct of the TPB model with behavioural intention can explain the young adult's safety behaviour in the laboratories and workshops with the variance of 40%.
