The future of experimental design: Integrative, but is the sample diverse enough?

Almaatouq et al. propose an "integrative approach" to increase the generalisability and commensurability of experiments. Yet their metascientific approach has one glaring omission (and misinterpretation of) - the role of sample diversity in generalisability. In this commentary, we challenge false notions of subsumed duality between contexts, population, and diversity, and propose modifications to their design space to accommodate sample diversity.

A guide for social science journal editors on easing into open science.

Journal editors have a large amount of power to advance open science in their respective fields by incentivising and mandating open policies and practices at their journals. The Data PASS Journal Editors Discussion Interface (JEDI, an online community for social science journal editors: www.dpjedi.org ) has collated several resources on embedding open science in journal editing ( www.dpjedi.org/resources ). However, it can be overwhelming as an editor new to open science practices to know where to start. For this reason, we created a guide for journal editors on how to get started with open science. The guide outlines steps that editors can take to implement open policies and practices within their journal, and goes through the what, why, how, and worries of each policy and practice. This manuscript introduces and summarizes the guide (full guide: https://doi.org/10.31219/osf.io/hstcx ).

Lack of Sample Diversity in Research on Adolescent Depression and Social Media Use: A Scoping Review and Meta-Analysis.

Research on whether social media use relates to adolescent depression is rapidly increasing. However, is it adequately representing the diversity of global adolescent populations? We conducted a preregistered scoping review (research published between 2018 and 2020; 34 articles) to investigate the proportion of studies recruiting samples from the Global North versus Global South and assess whether the association between social media and depression varies depending on the population being studied. Sample diversity was lacking between regions: More than 70% of studies examined Global North populations. The link between social media and depression was positive and significant in the Global North but null and nonsignificant in the Global South. There was also little evidence of diversity within regions in both sampling choices and reporting of participants' demographics. Given that most adolescents live in the Global South and sample diversity is crucial for the generalizability of research findings, urgent action is needed to address these oversights.

Digital access constraints predict worse mental health among adolescents during COVID-19.

The COVID-19 pandemic and ensuing social restrictions disrupted young people's social interactions and resulted in several periods during which school closures necessitated online learning. We hypothesised that digitally excluded young people would demonstrate greater deterioration in their mental health than their digitally connected peers during this time. We analysed representative mental health data from a sample of UK 10-15-year-olds (N = 1387) who completed a mental health inventory in 2017-2019 and thrice during the pandemic (July 2020, November 2020 and March 2021). We employed longitudinal modelling to describe trajectories of adolescent mental health for participants with and without access to a computer or a good internet connection for schoolwork. Adolescent mental health symptoms rose early in the COVID-19 pandemic, with the highest mean Total Difficulties score around December 2020. The worsening and subsequent recovery of mental health during the pandemic was greatly pronounced among those without access to a computer, although we did not find evidence for a similar effect among those without a good internet connection. We conclude that lack of access to a computer is a tractable risk factor that likely compounds other adversities facing children and young people during periods of social isolation or educational disruption.

Social media and adolescent well-being in the Global South.

Despite the rapid proliferation of digital technologies in the Global South, most academic research on social media and adolescent well-being has primarily focused on the Global North. This review investigates how social media impacts adolescent well-being in the Global South. We first review five regions (Sub-Saharan Africa, Middle East & North Africa, Latin America, China and South & South-East Asia) to highlight the complex ways social media interacts with well-being around the world. We then outline research gaps in the current understanding of the impacts of social media use on adolescent populations in diverse cultural contexts. We finally highlight potential lines of inquiry that future researchers could explore to build a nuanced, contextual perspective of the risks and opportunities of social media use.
