Understanding healthcare worker's intention to donate blood: an application of the theory of planned behaviour

This study aims to identify the influencing factor towards the intention to donate blood using the Theory of Planned Behaviour (TPB) model among healthcare workers (HCWs). A random sample of 400 HCWs from the population received the survey via a web-based link. The hypothesised model was tested using structural equation modelling. The median (interquartile range) age of respondents was 31.0 (11.0) years with female accounting for 75.5% (n = 302). Overall, 60.3% (n = 241) have donated blood. The final structural model showed a good fit of the data: CFI = 0.972; TLI = 0.976; RMSEA = 0.052; SRMR = 0.064. Perceived behavioural control and age significantly influenced the HCW's intention to donate blood. The final model explained 43% of the total variance in intention to donate blood. The findings provide a vital message to focus on some barriers and motivational factors of blood donation behaviour among HCWs.
