administrative divisions of Sarawak. Data on perceived tobacco control law, knowledge of the effects of SHS on health and environment,
attitude and support towards smoke-free eating-places, and current smoke-free eating-places were collected by face-to-face
interview using a structured questionnaire. A partial least squares model was developed to examine the impact of knowledge, attitude,
and support towards the smoke-free eating-places with the current practice of smoke-free eating-places. WarpPLS version ۷.۰
was used to examine the structural path and to test the hypothesis.
Results: The structural path analysis revealed that perceived knowledge of tobacco control lawhad no impact on practicing smokefree
eating-places (P > ۰.۰۵). However, the knowledge of the health and environmental effects of SHS had direct and indirect effects
on attitude and support for smoke-free eating-places (P < ۰.۰۰۱). In addition, attitude towards smoke-free eating-places had a significant
mediating effect on practicing smoke-free eating-places (P < ۰.۰۰۱). Besides that, supporting smoke-free eating-places had
a significant direct impact on the practice of smoke-free eating-places (P < ۰.۰۰۱).
Conclusions: Legislation and implementation of smoke-free eating-places along with the antismoking program and education
efforts could support the cessation of tobacco use in all public places, including all eateries.
