Abstract

Background

Smoking prevalence among people experiencing homelessness is high. This study explored the factors which influenced potential smoking abstinence among participants receiving an e-cigarette (EC) intervention within the Smoking Cessation Trial in Centres for Homelessness (SCeTCH) across Great Britian.

Methods

Using the Capability Opportunity Motivation – Behaviour (COM-B) model, hypothesised and emerging mediators were explored quantitatively via measures in baseline and follow-up questionnaires (n=239) and qualitatively via interviews with homelessness centre staff (n=16) and participants (n=31) who received an EC starter pack and 4-week e-liquid supply. We purposively sampled 8 centres for interviews, representing varied regions and participant vaping/smoking and sociodemographic status. Quantitative measures were analysed descriptively. Qualitative data were analysed thematically. Data from the two approaches were mapped onto the COM-B for combined analysis and reporting.

Results

After receiving the intervention, participants demonstrated high capability to use EC and appreciation of EC for harm reduction. Some participants reported dissatisfaction with vaping. Opportunity for behaviour change was strengthened by perceived acceptability to vape and social support beyond the centre but hindered by a smoking culture and perceived lack of staff support. Motivation was enhanced by EC efficacy belief, pride from cutting down, and financial benefits of vaping, but negatively impacted by challenging personal circumstances.

Conclusion

For people accessing homelessness support centres, smoking abstinence remains challenging. More intensive support and a variety of approaches to support smoking cessation, particularly those which address the psychosocial factors which hinder smoking abstinence, may be required. Future research should focus on how this can be achieved.

探索电子烟干预如何影响获得无家可归服务的人的吸烟行为：SCeTCH试验过程评估的结果

背景无家可归者的吸烟率很高。本研究探讨了在英国无家可归中心（SCeTCH）戒烟试验中接受电子烟（EC）干预的参与者的潜在戒烟影响因素。方法采用能力-机会-动机-行为（comb）模型，通过基线和随访问卷（n=239）的测量，对假设的和新兴的中介进行定量探索，并通过对无家可归中心工作人员（n=16）和接受EC入门包和4周电子液体供应的参与者（n=31）的访谈，对假设的和新兴的中介进行定性探讨。我们有针对性地选取了8个中心进行访谈，代表了不同的地区和参与者的电子烟/吸烟和社会人口状况。定量措施进行了描述性分析。对定性数据进行专题分析。两种方法的数据被映射到COM-B上进行联合分析和报告。结果接受干预后，参与者表现出较高的使用电子商务的能力和对电子商务减少伤害的认识。一些参与者对电子烟表示不满。对电子烟的可接受性和中心以外的社会支持加强了行为改变的机会，但由于吸烟文化和缺乏工作人员支持而受到阻碍。电子烟的功效信念、减少吸电子烟的自豪感和经济利益增强了动机，但挑战性的个人环境会对动机产生负面影响。结论对于寻求无家可归者支持中心的人来说，戒烟仍然具有挑战性。可能需要更密集的支持和各种支持戒烟的方法，特别是那些解决阻碍戒烟的心理社会因素的方法。未来的研究应侧重于如何实现这一目标。

期刊介绍： The International Journal of Drug Policy provides a forum for the dissemination of current research, reviews, debate, and critical analysis on drug use and drug policy in a global context. It seeks to publish material on the social, political, legal, and health contexts of psychoactive substance use, both licit and illicit. The journal is particularly concerned to explore the effects of drug policy and practice on drug-using behaviour and its health and social consequences. It is the policy of the journal to represent a wide range of material on drug-related matters from around the world.
