Does Self-Reported smoking cessation fatigue predict making quit attempts and sustained abstinence among adults who smoke Regularly?

Background: Quitting smoking is difficult and many people who smoke experience cessation fatigue (CF) as a result of multiple failed attempts. This study examined the association of CF with making and sustaining a smoking quit attempt.

Methods: Data analysed were 4,139 adults (aged 18 years or older) who smoked daily or weekly and participated in the 2018 and 2020 International Tobacco Control Four Country Smoking and Vaping Surveys (ITC 4CV) conducted in Australia, Canada, England, and the US.
