Abstract

OBJECTIVE: To examine components of the Health Belief Model (HBM) as mediators and socio-demographic characteristics as moderators of the effects of an educational intervention on intention to practise pneumoconiosis prevention among South Asian construction workers. METHODS: The study used a one-group pretest and posttest design. Analytic data was from 1001 South Asian construction workers in Hong Kong. RESULTS: Changes in the perceived susceptibility, perceived severity, perceived benefits, cues to action, and self-efficacy mediated the intervention's efficacy in improving intention to practise pneumoconiosis prevention. The intervention was more effective in reducing perceived barriers in younger workers, enhancing self-efficacy in older workers and relatively new employees, and improving the intention in unmarried workers. CONCLUSIONS: It provided preliminary support for the efficacy of the intervention based on the HBM in improving intention to practise pneumoconiosis prevention among South Asian construction workers.
