Teenagers, screens and social media: a narrative review of reviews and key studies
IntroductionIn light of growing concerns about an increasingly digital adolescence, the academic field investigating how digital technologies affect adolescents’ psychological well-being is growing rapidly. In the last years, much research has amassed, and this has been summarised in over 80 systematic reviews and meta-analyses.Materials and MethodsSystematic reviews, meta-analyses and key studies are reviewed to provide insights into the state of current research linking digital technology and social media use to well-being; possible future directions and improvements are discussed.ResultsWhen examining the reviews, it becomes evident that the research field is dominated by cross-sectional work that is generally of a low quality standard. While research has highlighted the importance of differentiating between different types of digital technology use many studies do not consider such necessary nuances. These limitations aside, the association between digital technology use, or social media use in particular, and psychological well-being is—on average—negative but very small. Furthermore, the direction of the link between digital technology use and well-being is still unclear: effects have been found to exist in both directions and there has been little work done to rule out potential confounders.ConclusionsReviewing the last decade of reviews in the area, it is evident that the research field needs to refocus on improving transparency, interpreting effect sizes and changing measurement. It also needs to show a greater appreciation for the individual differences that will inherently shape each adolescent’s reaction to digital technologies.

Impacts of digital technologies on education and factors influencing schools' digital capacity and transformation: A literature review
Digital technologies have brought changes to the nature and scope of education and led education systems worldwide to adopt strategies and policies for ICT integration. The latter brought about issues regarding the quality of teaching and learning with ICTs, especially concerning the understanding, adaptation, and design of the education systems in accordance with current technological trends. These issues were emphasized during the recent COVID-19 pandemic that accelerated the use of digital technologies in education, generating questions regarding digitalization in schools. Specifically, many schools demonstrated a lack of experience and low digital capacity, which resulted in widening gaps, inequalities, and learning losses. Such results have engendered the need for schools to learn and build upon the experience to enhance their digital capacity and preparedness, increase their digitalization levels, and achieve a successful digital transformation. Given that the integration of digital technologies is a complex and continuous process that impacts different actors within the school ecosystem, there is a need to show how these impacts are interconnected and identify the factors that can encourage an effective and efficient change in the school environments. For this purpose, we conducted a non-systematic literature review. The results of the literature review were organized thematically based on the evidence presented about the impact of digital technology on education and the factors that affect the schools’ digital capacity and digital transformation. The findings suggest that ICT integration in schools impacts more than just students’ performance; it affects several other school-related aspects and stakeholders, too. Furthermore, various factors affect the impact of digital technologies on education. These factors are interconnected and play a vital role in the digital transformation process. The study results shed light on how ICTs can positively contribute to the digital transformation of schools and which factors should be considered for schools to achieve effective and efficient change.

Young People’s Use of Digital Health Technologies in the Global North: Narrative Review
A diverse array of digital technologies are available to children and young people living in the Global North to monitor, manage, and promote their health and well-being.
This article provides a narrative literature review of the growing number of social research studies published over the past decade that investigate the types of digital technologies used by children and young people in the Global North, in addition to investigating which of these technologies they find most useful or not useful. Key findings as well as major gaps and directions for future research are identified and discussed.
A comprehensive search of relevant publications listed in Google Scholar was conducted, supported by following citation trails of these publications. The findings are listed under type of digital technology used for health: cross-media, internet, social media, apps and wearable devices, sexual health support and information, and mental health support and information.
Many young people in the Global North are active users of digital health technologies. However, it is notable that they still rely on older technologies, such as websites and search engines, to find information. Apps and platforms that may not have been specifically developed for young people as digital health resources often better suit their needs. Young people appreciate the ready availability of information online, the opportunities to learn more about their bodies and health states, and the opportunities to learn how to improve their health and physical fitness. They enjoy being able to connect with peers, and they find emotional support and relief from distress by using social media platforms, YouTube, and online forums. Young people can find the vast reams of information available to them difficult to navigate. They often look to trusted adults to help them make sense of the information they find online and to provide alternative sources of information and support. Face-to-face interactions with these trusted providers remain important to young people. Risks and harms that young people report from digital health use include becoming overly obsessed with their bodies' shape and size when using self-tracking technologies and comparing their bodies with the social media influencers they follow.
Further details on how young people are using social media platforms and YouTube as health support resources and for peer-to-peer sharing of information, including attention paid to the content of these resources and the role played by young social media influencers and microcelebrities, would contribute important insights to this body of literature. The role played by visual media, such as GIFs (Graphics Interchange Format) and memes, and social media platforms that have recently become very popular with young people (eg, Snapchat and TikTok) in health-related content creation and sharing requires more attention by social researchers seeking to better understand young people's use of digital devices and software for health and fitness.

The politics of digital India : between local compulsions and transnational pressures
This book locates Digital India in context. It deals with the many ways in which Digital India is shaped by local pressures and political expediencies as much as by global pressures, namely from one of India's strongest allies, the USA. However, this relationship with the USA is by no means straightforward and this book illustrates the highs and lows of this relationship. As importantly, this book deals with the larger Indian reality in which the digital is but one sector, albeit an increasingly important one. There are other sectors including agriculture and the informal sectors on which many million Indians depend on their livelihoods. These sectors too are becoming exposed to the digital and this has resulted in the presence of multiple digital spheres in India. This book deals with the ambivalent Indian State that is on the one hand attempting to control its citizens through some of these digital spheres while also investing in public access projects such as Digital India and resisting the power of Big Brother, namely the USA. This is an important contribution to understanding Digital India precisely because it attempts to account for some of its complexities.

Searching for New Technology Acceptance Model under Social Context: Analyzing the Determinants of Acceptance of Intelligent Information Technology in Digital Transformation and Implications for the Requisites of Digital Sustainability
Intelligent information technology (IIT) based on AI and intelligent network communication technology is rapidly changing the social structure and the personal lives. However, IIT acceptancefrom various perspectives still requires extensive research. The research question in this paper examines how five factors—psychological, technological, resource, risk perception, and value factors—influence IIT acceptance. Based on an analysis of survey data, it was first found that the acceptance rate of IIT itself was generally very high. Second, in terms of IIT acceptance, among twenty-five predictors, voluntariness (+), positive image of technology (+), performance expectancy (+), relative advantage (+), radical innovation (+), and experience of use (+) were found to have significant effects on the IIT acceptance. Third, in addition to technological factors, psychological factors and risk perception factors also played an important role in individuals’ decisions regarding IIT acceptance.

Background
With advances in technology, digital technology has played an important role in various fields. In palliative care, the application of digital technology interventions has provided new methods for managing symptoms for patients and their families, as well as for the provision of services for healthcare workers.
Objectives
To conduct a scoping review of the literature on the application of digital technology interventions in palliative care and to provide a reference for digital technology interventions and related research.
Methods
A systematic search of studies on the application of digital technology interventions in palliative care in China National Knowledge Infrastructure (CNKI), Wanfang, VIP, PubMed, Web of Science, and the Cochrane Library was conducted, with the search period from the establishment of the databases until June 18, 2025. Inclusion criteria: Chinese or English, patients, caregivers, and healthcare workers as target populations, and the combination of digital technology intervention in palliative care, digital tools are primarily designed for web-based platforms, applications, wearable devices, virtual reality (VR), and Artificial intelligence (AI) decision tools.
Results
Twenty-one articles were included in the analysis. In palliative care, digital technology interventions mainly include short videos, web-based platforms, and VR. The content of the intervention included health education, symptom management, and relaxation experience, and the main outcome indicators were mood, quality of life, pain, symptom-related system, and family social support. The application effect is concentrated on psychological and emotional support, quality of life, symptom improvement, and social, medical, and nursing aspects.
Conclusions
Technology has significant positive effects on the application of palliative care, such as alleviating negative emotions, improving quality of life, and enhancing social support. However, in the application of digital technology in palliative care, the aspects of technology that assist in the guidance of personnel and the support of social funds should be strengthened, so that the application of technology in palliative care can have broader application potential.
