Background: Age is associated with smoking behavior. However, scarce research has explored its role in smoking cessation outcomes in digital interventions to quit. The present study aims to assess the effect of age on a blended smoking cessation cognitive-behavioral treatment that includes an App. Method: The sample (N = 154) was divided into two groups: 18-44 years old vs. 45 years or older, based on the mean age of the overall sample. Results: Participants aged 18 to 44 were more likely to be abstinent than those aged 45 years or older at the end of treatment and at the 6-month follow-up. There was a significant effect of age on point-prevalence abstinence over time (OR = 1.91). Conclusions: Findings suggest that age is a relevant variable in digital interventions to quit smoking and that including an App as an adjunct could be especially relevant for younger people seeking cessation treatment.
