In addition, in her dissertation, the researcher confirms the evidence for the effectiveness of the Dutch telephone smoking cessation coaching programme Smoke-free Parents for parents of children aged 0–18, and there are indications that this coaching may also be cost-effective. “Parents who received the telephone coaching were more than seven times as likely to have quit smoking three months later as parents who had received a self-help brochure about quitting smoking.”

Finally, her dissertation shows that the telephone coaching programme Smoke-free Parents can be implemented through healthcare professionals, such as paediatricians, and the website www.ikstopnu.nl, and there are implications for how the implementation of Smoke-free Parents can be improved. Based on the results of this dissertation, the telephone coaching programme Smoke-free Parents has been implemented nationwide since the end of 2019, and several parents are referred to it every week.

Scheffers-van Schayck received her PhD with her dissertation ‘Smoke-free Parents: Providing a smoke-free future for parents and their children’ on 10 June at Utrecht University.
