Smartphone-based personal carbon monoxide (CO) monitors and associated apps, or "CO Smartphone Systems" (CSSs) for short, could enable smokers to independently monitor their smoking and quitting. This study explored views and preferences regarding CSSs and their use among 16 adult, UK-based smokers. First, semi-structured interviews explored participants' expectations of CSSs. Secondly, a think-aloud study identified participants' reactions to a personal CO monitor and to existing or prototype apps. Framework Analysis identified five themes: (1) General views, needs, and motivation to use CSSs; (2) Views on the personal CO monitor; (3) Practicalities of CSS use; (4) Desired features in associated apps; and (5) Factors affecting preferences for CSSs and their use. Participants had high expectations of CSSs and their potential to increase motivation. Priority app features included: easy CO testing journeys, relevant and motivating feedback, and recording of contextual data. Appearance and usability of the personal CO monitor, and accuracy and relevance of CO testing were considered important for engagement. Participants differed in their motivation to use and preferences for CSSs features and use, which might have non-trivial impact on evaluation efforts. Personal CO monitors and associated apps may be attractive tools for smokers, but making CSSs easy to use and evaluating these among different groups of smokers may be challenging.
基于智能手机的个人一氧化碳（CO）监测器及相关应用，简称“CO 智能手机系统”（CSS），可使吸烟者能够独立监测自己的吸烟和戒烟情况。本研究探讨了 16 名英国成年吸烟者对 CSS 及其使用的看法和偏好。首先，半结构化访谈探讨了参与者对 CSS 的期望。其次，通过出声思维研究，确定了参与者对个人 CO 监测器以及现有或原型应用程序的反应。框架分析确定了五个主题：（1）使用 CSS 的一般看法、需求和动机；（2）对个人 CO 监测器的看法；（3）CSS 使用的实际情况；（4）相关应用程序中所需的功能；（5）影响 CSS 及其使用偏好的因素。参与者对 CSS 及其潜在的提高动机的能力抱有很高的期望。优先考虑的应用程序功能包括：简单的 CO 测试流程、相关且有激励性的反馈，以及记录背景数据。个人 CO 监测器的外观和可用性，以及 CO 测试的准确性和相关性，被认为是参与的重要因素。参与者对 CSS 及其使用的功能和偏好的使用动机存在差异，这可能对评估工作产生重大影响。个人 CO 监测器和相关应用程序可能是吸烟者的有吸引力的工具，但使 CSS 易于使用并在不同的吸烟者群体中进行评估可能具有挑战性。
