SCAMP Wave 2

精神疾病通常出现在青春期，但其原因尚不清楚。青春期是家庭、学校和同伴关系、手机/社交媒体的使用(即数字技术的使用)、认知(即人们如何思考、决策和处理信息)、青春期荷尔蒙和体育活动的巨大变化时期。此前的研究表明，过度使用数字技术与心理健康状况不佳之间存在联系。然而，这种联系可以用各种因素来解释，比如认知、青春期荷尔蒙、人们做了多少体育活动，或者肥胖。目前，几乎没有科学证据表明哪些因素是罪魁祸首，以及它们可能如何相互作用。心理健康很可能会因个人的基因、性别、财富、社会阶层和种族而异，了解这种差异很重要，以确定人群中可能更容易受到数字技术使用的负面影响的群体。认知、青少年和手机研究(SCAMP)是关于青春期数字技术使用和认知的最大长期研究。这是目前唯一一项可以回答详细研究问题的研究，这些问题是关于当今数字时代青少年使用数字技术可能会如何影响他们进入成年后的心理健康。我们之前收集了约6,600名11-15岁的SCAMP研究参与者的数据，包括他们如何使用数字设备、他们的认知、身心健康和生活方式(例如吸烟和饮食)，以及尿液和唾液样本(以测量青春期激素水平)，以及身体测量数据，如身高和体重。在这里，我们计划通过面对面的会议收集17/18岁的SCAMP参与者的数据、样本(尿液和唾液)和身体测量，我们将要求SCAMP参与者下载一款应用程序，以便我们可以在3-4年内继续远程收集数据。包括参与者离开学校后。我们将要求参与者佩戴健身跟踪器腕带长达2个月，这样我们就可以收集准确的体力活动数据。如果参与者允许，我们还将链接到他们例行收集的健康和教育记录。拟议的数据收集浪潮将允许对参与者从青春期进入成年期间的心理健康、认知、数字技术使用、生活方式和身体健康进行持续和更深入的评估。我们将从参与者提供的生物样本中分析遗传学，以获得关于遗传变异的数据。我们将使用这些数据来调查以下研究问题：1)过度使用数字技术与心理健康不良之间的关系是否可以通过缺乏体育活动或肥胖来解释？2)青春期认知发展和青春期是否解释了数字技术使用与心理健康之间的关系？3)一些人是否由于基因原因比其他人更容易受到数字技术使用对心理健康的影响？这项研究将解决目前关于数字技术使用与心理健康之间联系的科学知识差距。它可能会让我们识别数字技术使用的特定方面，这些方面会增加个人心理健康不良的风险，或者生活方式的特定方面是“保护”的，并提高心理健康。我们的建议具有很高的政策相关性，无论是在国内还是在国际上，对于采取行动预防早期生活中的精神疾病来说，政府和教育层面都是如此。在利益相关者共同设计的支持下，我们的目标是确保我们的研究结果为未来以证据为基础的精神健康政策和干预措施的制定提供信息，以提高年轻人的生活质量，并为社会提供长期经济利益。

Mental illness commonly emerges during adolescence, but the reasons for this are not well understood. Adolescence is a period of great change in family, school, and peer relationships, use of mobile phones/social media (i.e. digital technology use), cognition (i.e. how people think, make decisions and process information), puberty hormones, and physical activity. Previous research has shown links between overuse of digital technology and poor mental health. However, this link could be explained by various factors, such as cognition, puberty hormones, how much physical activity people do, or obesity. There is currently little scientific evidence on which factors are responsible and how they might all interact with one another. It is likely that mental health varies according to an individual's genes, gender, wealth, social class and ethnicity, and it is important to understand this variation to identify groups in the population who may be more susceptible to the negative impacts of digital technology use. The Study of Cognition, Adolescents and Mobile Phones (SCAMP) is the largest long-term study of digital technology use and cognition in adolescence. It is currently the only study that can answer detailed research questions about how digital technology used by adolescents in today's digital era may affect their mental health as they move into adulthood. We previously collected data from ~6,600 SCAMP study participants ages 11-15 about how they use digital devices, their cognition, physical and mental health, and lifestyle (e.g. smoking and diet), together with urine and saliva samples (to measure e.g. puberty hormone levels), and physical measurements e.g. height and weight.Here, we plan to collect data, samples (urine and saliva), and physical measurements from SCAMP participants at ages 17/18 at a face-to-face session, and we will ask SCAMP participants to download an app so that we can continue to collect data remotely for 3-4 years, including after participants have left school. We will ask participants to wear a fitness tracker wristband for up to 2 months so that we can collect accurate data on physical activity. We will also link to participants' routinely collected health and educational records if they permit this. The proposed waves of data collection will allow continued and more in-depth assessment of participants' mental health, cognition, digital technology use, lifestyle, and physical health during the time period when they move from adolescence into adulthood. We will analyse genetics from biological samples provided by participants to obtain data on genetic variation. We will use these data to investigate research questions such as: 1) is the relationship between overuse of digital technology and poor mental health explained by lack of physical activity, or obesity?; 2) does cognitive development and puberty during adolescence explain relationships between digital technology use and mental health?; and 3) are some people more susceptible to the impacts of digital technology use on mental health than others, due to their genes?This research will address current gaps in scientific knowledge about links between digital technology use and mental health. It may allow us to identify specific aspects of digital technology use that increase an individual's risk of poor mental health, or specific aspects of lifestyle that are "protective" and boost mental wellbeing. Our proposal has high policy relevance, both nationally and internationally, at government and education levels for action to prevent mental illness in early life. Supported by co-design from stakeholders, we aim to ensure that our research findings inform the development of future evidence-based policies and interventions for mental health to enhance quality of life for young people and provide long-term economic benefits to society.
