Developing a brief, immersive virtual reality scenario for smokers unmotivated to quit through user-centred design

吸烟是过早健康不良和死亡的主要原因，与50多种严重健康状况有关。大多数吸烟者都很了解吸烟对健康的影响，但大多数人缺乏戒烟的动力（Brose等人，2020年）。戒烟的动机是戒烟尝试的关键预测因素，但在英国，大约80-85%的吸烟者没有戒烟的意图。缺乏专门针对无戒烟动机的吸烟者的个人干预措施。虚拟现实（VR）（一种有可能唤起强烈且看似真实的感官体验的数字环境）可能提供一种有希望的沉浸式手段，促使没有戒烟动机的人尝试戒烟，否则不会发生。开发新的干预措施来激励吸烟者戒烟可能会对公共卫生产生重大影响。因此，该项目的目的是支持开发数字干预措施，利用基于理论的框架激励吸烟者戒烟，重点是解决数字鸿沟和排斥问题。关键的研究问题可能包括但不限于：1）吸烟者对使用VR鼓励戒烟的看法是什么？2)吸烟者希望在VR干预中看到哪些关键内容和设计特征，以增加戒烟的动力？3)VR和基于理论的戒烟干预的专家认为哪些内容和设计特征是VR场景中增加吸烟者戒烟动机的关键和可行的？4)吸烟者对开发的VR原型有什么体验（将基于RQ 1，RQ 2，RQ 3的结果）？5)VR原型的可接受特征是什么？6)在大规模评估之前，VR原型应该做哪些关键更改？

Cigarette smoking is a leading cause of premature ill-health and death and is associated with more than 50 serious health conditions. The majority of smokers are well informed about the health consequences of smoking, but most lack motivation to quit smoking (Brose et al., 2020). Motivation to stop smoking is a key predictor of quit attempts but approximately 80-85% of smokers in England do not have an intention to stop. There is a scarcity of individual-level interventions designed specifically for smokers unmotivated to quit. Virtual reality (VR) (a digital environment that has the potential to evoke strong and seemingly real sensory experiences) may offer a promising, immersive means of prompting quit attempts among people unmotivated to quit that would otherwise not occur. Developing, new interventions to motivate smokers to quit smoking could have a significant public health impact. Thus, the aim of this project is to support development of a digital intervention to motivate smokers to quit smoking using a theory-based framework, with a focus on addressing digital divides and exclusion. Key research questions may include but are not limited to:1) What are smokers' views of using VR to encourage a quit attempt?2) What are the key content and design features that smokers would like to see in a VR intervention to increase motivation to quit?3) What content and design features do experts in VR and theory-based smoking cessation interventions identify as critical and feasible to include in the VR scenario to increase smokers' motivation to quit?4) What are smokers' experiences of the developed VR prototype (which will be based on the results of RQ1, RQ2, RQ3)?5) What are the acceptable features of the VR prototype?6) What are the key changes of the VR prototype that should be made prior to large-scale evaluation?
