Self-monitoring of online food purchases: development of the myShop app

大多数英国超市都提供在线订购食品和饮料的服务，在线超市购物正在迅速扩张。这项研究的目的是开发在线工具来帮助购物者购买更健康的食品。我们正在开发一个名为myShop的在线工具。作为myShop应用程序的一部分，我们已经开发了一个可以在六家在线超市（Tesco, Sainsbury, Asda, Morrison， Ocado和Waitrose）使用的工具。当使用这个工具时，购物者在购物时，包括在搜索和选择，看他们的篮子和结账时，所有物品和他们的总食物上都有红绿灯标签。这使得用户可以很容易地比较不同产品的健康程度。大多数商店只在查看每种食品的详细网页时显示红绿灯标签，甚至这种规定也很少。在myShop中，标签只是出现在实际的超市网站上，因此用户在现实生活中正常购物时很容易访问。该应用程序还可以选择不显示不健康的产品，以避免诱惑。在这个项目中，我们将开发myShop网站（可以在平板电脑，智能手机或PC上使用），帮助购物者使用myShop应用程序来吃更健康的饮食。新网站将允许用户选择、设置和改变他们的健康饮食目标，并看到他们的食品购物健康程度随时间的变化（通过查看图表）。他们还可以得到购物建议，关于他们如何做的反馈和提醒。为了使“我的商店”应用程序发挥最大的作用，我们将成立一个研究小组的指导小组和两名公众成员，他们将监督这个项目。我们将对以前的研究进行回顾，以找到帮助人们改变饮食习惯的证据。我们将使用这些证据和如何支持行为改变的良好证明理论来制定计划，概述应用程序的内容和设计所需的内容。我们将与一家经验丰富的网站开发公司合作，制作网站的第一版。然后，我们将对大约20名公众进行“自言自语”的采访，这意味着让他们试用网站，同时我们记录他们使用网站的看法。我们将利用这些反馈来改进网站，并将进行更多的访谈来试用新版本，直到我们尽我们所能地改进它。我们将询问不同年龄、不同教育程度和上网经验的男性和女性，以确保网站适合所有类型的人。最后，我们将邀请另外20位公众在现实生活中使用这个网站几个星期（至少做两个网上商店），我们将采访他们，看看它是否有帮助或需要在任何方面进行改变。在项目结束时，我们将为一个更大的研究申请资金，看看这个网站是否真的能帮助人们改善饮食。

Most UK supermarkets offer an online supermarket for ordering food and drink to be delivered and online supermarket shopping is expanding rapidly. The aim of this study is to develop online tools to help shoppers buy more healthy food. We are developing an online tool called the myShop app. As part of the myShop app, we have already developed a tool that can be used in six online supermarkets (Tesco, Sainsbury, Asda, Morrison, Ocado and Waitrose). When using this tool, the shopper is presented with traffic light labelling on all items and their total food at all times when shopping, including when searching and choosing, looking at their basket and at checkout. This allows users to easily compare the healthiness of different products. Most shops only display traffic light labelling when viewing the detailed webpage for each food and even this provision is infrequent. With myShop, the labelling simply appears on the actual supermarket websites, so the user has easy access during their normal shopping in real life. The app can also be used to choose to not be shown unhealthy products to avoid temptation. For this project we will develop the myShop website (which can be used on tablet, smart-phone or PC) to help shoppers use the myShop app to eat a more healthy diet. The new website will allow users to choose, set and change their healthy eating goals and see changes in how healthy their food shopping is over time (by viewing a graph). They will also be able to get shopping advice, feedback on how they are doing and reminders.To make the myShop app as useful as possible, we will form a steering group of the research team and two members of the public, who will oversee the project. We will carry out a review of previous studies to find evidence about what has helped people change their diet. We will use this evidence and well proven theories of how to support behaviour change to develop a plan that outlines what is needed for the content and design of the app. We will work with a very experienced website development company to produce a first version of the website. We will then carry out 'think aloud' interviews with around 20 members of the public, which means asking them to try out the website while we record their views of using it. We will use this feedback to improve the website, and will carry out more interviews to try out the new version, until we have improved it as much as we can. We will ask men and women of different ages and with different levels of education and online experience, to make sure the website is suitable for all types of people. Finally, we will ask another 20 members of the public to use the website in real life for a few weeks (to do at least two online shops), and we will interview them to find out if it is helpful or needs to be changed in any way. At the end of the project we will apply for funding for a bigger study to see whether the website does help people improve their diet.
