Barriers and Facilitators to Engaging in Smoking Cessation Support Among Lung Screening Participants

Résumé fourni par la source

INTRODUCTION: Embedded smoking cessation support within lung cancer screening is recommended in the United Kingdom; however, little is known about why individuals decline smoking cessation support in this setting. This study identified psychosocial factors that influence smoking cessation and quit motivation among those who declined support for quitting smoking alongside lung cancer screening. AIMS AND METHODS: Qualitative interviews were conducted between August 2019 and April 2021 with 30 adults with a smoking history, recruited from the Yorkshire Lung Screening Trial. Participants had declined smoking cessation support. Verbatim interview transcripts were thematically analyzed. RESULTS: Fifty percent of participants were male and the majority were from the most deprived groups. Participants reported low motivation and a variety of barriers to stopping smoking. Participants described modifiable behavioral factors that influenced their quit motivation including self-efficacy, perceived effectiveness of stop-smoking services including smoking cessation aids, risk-minimizing beliefs, lack of social support, absence of positive influences on smoking, and beliefs about smoking/smoking cessation. Broader contextual factors included social isolation and stigma, coronavirus disease 2019, and comorbid mental and physical health conditions that deterred smoking cessation. CONCLUSIONS: To encourage engagement in smoking cessation support during lung cancer screening, interventions should seek to encourage positive beliefs about the effectiveness of smoking cessation aids and increase confidence in quitting as part of supportive, person-centered care. Interventions should also acknowledge the wider social determinants of health among the lung screening-eligible population. IMPLICATIONS: This study provides an in-depth understanding of the beliefs surrounding smoking and smoking cessation and further potential psychosocial factors that influence those attending lung cancer screening. Many of the barriers to smoking cessation found in the present study are similar to those outside of a lung screening setting however this work offers an understanding of potential facilitators that should be considered in future lung screening programs.
