Malaysia is facing a shortage of blood supply despite blood donation campaigns and drives; the
number of donors remains low. Understanding donors and potential donors will provide a basis to
develop effective approaches of reaching them. Therefore, this study was conducted to identify
specific socio-demographic characteristics and factors influencing the intention to donate blood among
working adults in Malaysia. Driven by positivist approach and based on the Theory of Planned
Behaviour, data were collected from 295 working adults. The data was analysed using Partial Least
Square Structural Equation Modelling (PLS-SEM) approach. The findings indicated that attitude,
subjective norms and perceived behavioural control are the predictors for working adult’s intention to
donate blood. The results revealed are believed to be valuable for the National Blood Centre to develop
strategies to motivate, recruit and sustain sufficient number of blood donors. It is suggested that future
studies should explore donor’s perception and expectation to identify factors that have positive or
negative effects on their motivation or have already deterred them from donating blood.
