Self-help smoking cessation intervention for Spanish-speaking Hispanics/Latinxs in the United States: A randomized controlled trial.

Research is needed to develop interventions for ethnic minority smokers. The aim of the current study was to test a Spanish-language adaptation of a validated and easily implemented self-help smoking cessation intervention in a nationwide randomized controlled trial. The findings demonstrated that the intervention produced greater smoking abstinence in comparison with a standard self-help booklet. Participants also were more satisfied with the intervention, and it was cost-effective. Efforts aimed at promoting tobacco abstinence in this underserved population could have significant public health implications, including potential reductions in cancer health disparities associated with tobacco smoking.
