Consumer perceptions of electrocardiography-enabled smartwatches in health management
Smartwatches with electrocardiography (ECG) functionality, capable of detecting cardiac arrhythmias, are promoted as accessible tools for early detection and prevention in cardiovascular healthcare. Despite their popularity, these devices have not been conclusively linked to improved long-term health outcomes – such as reduced stroke risk – in large scale randomized controlled trials. This raises the question whether popularity is driven by healt…
Nudging Towards Exposure Diversity
Scholars are increasingly studying how news recommenders can provide audiences with diverse news offers. However, despite their increased interest, little research has been conducted on how news audiences engage with news recommenders. This article assesses how a news recommender's design affects people's news exposure behaviours and perceptions. To do so, we conducted an online experiment (n = 337) in a virtual news environment with four differe…
A dyadic multimethod study of “partner phubbing”, smartphone conflict, and relationship quality in opposite-sex couples from Belgium
Existing research indicates that ‘partner phubbing’ is associated with heightened conflict and lower relationship satisfaction. However, previous studies have relied on cross-sectional designs involving subjective self-reports of only one partner. In this study, the main hypothesis entailed that the link between partner phubbing and relationship quality will be mediated by conflict over smartphone use. We utilized experience sampling (ESM) with o…
Trust in algorithmic decision-making systems in health
Algorithmic decision-making systems (ADMs) support an ever-growing number of decision-making processes. We conducted an online survey study in Flanders (n = 1,082) to understand how laypeople perceive and trust health ADMs. Inspired by the ability, benevolence, and integrity trustworthiness model (Mayer et al., 1995), this study investigated how trust is constructed in health ADMs. In addition, we investigated how trust construction differs betwe…
Why, how, when, and for whom does digital disconnection work? A process-based framework of digital disconnection
Digital disconnection has emerged as a concept describing the actions people take to limit their digital connectivity to enhance their well-being. To date, evidence on its effectiveness is mixed, leading to calls for greater consideration of why, how, when, and for whom digital disconnection works. This article responds to these calls, presenting a framework that differentiates four key harms that contribute to experiences of digital ill-being (t…
Decoding Algorithms
Algorithmic recommenders are omnipresent in our daily lives. While a multitude of studies focus on how people use algorithmic recommenders, far too little attention has been devoted to how they perceive and understand these complex systems. In this study we focus on Algorithmic News Recommenders (ANR). Drawing on 26 semi-structured interviews, we investigated how laypeople decode Google News and Facebook News. In our method we employ the scroll-b…
Predicting Teens' Privacy Management and Attitude Toward Data Protection on Social Media
This study contributes to ongoing debates on the protection of teens' privacy on social media. While ample research is focused on teens' privacy management, less is known about their attitude toward data protection. Drawing from cross-sectional survey data, this study examines whether predictors of privacy management, namely privacy literacy, privacy concern, and perceptions of data control, also predict teens' attitude toward data protection. St…
Paying for News Diversity? A Topic Diversity Analysis of Free and Paywalled Online News
Media companies increasingly place (parts of) their online news content behind to compensate for shrinking digital advertising revenues. However, despite its prominence in the contemporary news environment, very few studies have assessed the effects of this practice on the diversity in the actual content provided to people. To fill this knowledge gap in scholarship, this study examines how diverse free and paid content is in several newspapers in…

Teenagers’ reflections on media literacy initiatives at school and everyday media literacy discourses
Often coined as digital natives, contemporary teens are ascribed a paradoxical status of skilled but vulnerable media users. Therefore, media literacy initiatives often target young audiences in order to mitigate detrimental media effects as well as to facilitate emancipatory media engagements. The literature on media literacy draws from diverse disciplines (e.g. educational sciences, media studies) and examines a wide range of thematic areas (e.…
Does parental smartphone use predict parents’ perceptions of family life? An examination of momentary associations between parental smartphone use, parental experiences of quality time, and parental p…
This article reports the findings of a multi-method study that explored whether frequency and duration of parental smartphone use in the presence of children is associated with parents’ perceptions of quality time and child restlessness, an indicator of difficult child behavior. Additionally, the study explored whether parental perceptions of technoference, respectively time displacement, mediate the association between smartphone use measures - …
Networked gift-giving
The reciprocal exchanges of messages, likes, and pictures on social media are typical expressions of mobile youth culture. After all, it is well-established that young people’s disclosure practices support their efforts to maintain relationships, gain autonomy, and, by large, consolidate a place in the world. What is often missing, however, is an exploration of how the specific socio-cultural contexts of ethno-religious minority youths shape and …
Generation Stream
This article aims to unravel modes of audiovisual consumption of teenagers (13–17-year-olds) in the era of connected viewing. Based on a mixed-method design the research seeks to unpack the complex interplay between four increasingly varying articulations that each shape the overall meaning and nature of audiovisual consumption: platform, screen, content and context. In the era of almost infinite media choice, the results demonstrate that teenage…

Does Dynamic Tailoring of A Narrative-Driven Exergame Result in Higher User Engagement among Adolescents? Results from A Cluster-Randomized Controlled Trial
Physical activity interventions for youth are direly needed given low adherence to physical activity guidelines, but many interventions suffer from low user engagement. Exergames that require bodily movement while played may provide an engaging form of physical activity intervention but are not perceived as engaging to all. This study aimed to evaluate whether dynamic tailoring in a narrative-driven mobile exergame for adolescents played in leisu…
Caught in the moment
Procrastination is an increasingly prevalent phenomenon. Although research suggests smartphones might be involved, little is known about the momentary association between different patterns of smartphone use and procrastination. In a preregistered study, 221 students ( M age = 20, 55% female) self-reported procrastination five times a day for 30 days (i.e., experience sampling method) while their smartphone use was continuously monitored (i.e., p…
In-between child’s play and teenage pop culture
TikTok’s popularity ignites anxieties about youths’ privacy on the short-video sharing social media platform. This is especially true for 8–12-year-old ‘tweens’. This study draws from in-depth interviews with tweens and their parents to explore perceptions of tweenhood, TikTok and privacy. In our investigation, we move beyond a developmental framework on childhood by taking into account how life stage categories are socio-culturally constructed. …

Appreciating News Algorithms
As news selection is increasingly controlled by algorithms, a growing number of scholars are exploring how news recommenders can serve public services. Despite aspirations towards public service algorithms, little is known about which type of news recommender people prefer, let alone about a news recommender that aims to promote societal values. This study aims to give insights into audiences’ perceptions to news recommenders and their underlying…
A first investigation into gender minority adolescents’ sexting experiences
INTRODUCTION: Gender minority adolescents, such as transgender, gender nonconforming, gender diverse and non-binary youth, may face unique challenges with regard to online sexual communication. They may be especially vulnerable for sexting-related risks. The aim of this study is to explore the sexting experiences of gender minority youth among a school-based sample. METHODS: This brief exploratory study reports on a survey that was conducted amon…
Exploring the Effect of In-Game Purchases on Mobile Game Use with Smartphone Trace Data
Microtransactions have become an integral part of the digital game industry. This has spurred researchers to explore the effects of this monetization strategy on players’ game enjoyment and intention to continue using the game. Hitherto, these relationships were exclusively investigated using cross-sectional survey designs. However, self-report measures tend to be only mildly correlated with actual media consumption. Moreover, cross-sectional des…
Video Journalism
News producers are increasingly experimenting with news in virtual reality and 360° video, which is often presented as the ultimate form of immersive journalism as it provides viewers with a first-person experience of a news event. Audiences are deemed to be more involved with the presented story, raising assumptions that they may be more engaged with the event and feel more empathic towards the subject of the story, especially in the case of for…
The Triple Articulation of Media Technologies in Audiovisual Media Consumption
This article departs from the concept of “double articulation” within domestication theory, which views media as both objects and texts. Unfortunately, its empirical application has been problematic because researchers tend to concentrate on the contextual, losing sight of specific meanings of objects and texts. Therefore, we subscribe to the concept of “triple articulation,” viewing the immediate sociospatial context of consumption as a specific…

Staying Informed and Bridging 'Social Distance
The authors explore patterns of smartphone use during the first weeks following the outbreak of the coronavirus disease 2019 pandemic in Belgium, focusing on citizens' use of smartphones to consume news and to communicate and interact with others. Unique smartphone tracking data from 2,778 Flemish adults reveal that at the height of the outbreak, people used their smartphone on average 45 minutes (28 percent) more than before the outbreak. The nu…
News Diversity Reconsidered
Concerns about selective exposure and disinformation in the digital news environment have brought the concept of news diversity to the forefront of academic debates. Despite its growing prominence in scholarly work, however, news diversity often remains hard to grasp. The current paper aims to re-assess what the concept of news diversity means in an evolving news ecology. To do so, we draw on three dominant conceptualizations of news and media di…

What’s APPening to news? A mixed-method audience-centred study on mobile news consumption
News is increasingly being consumed on a multitude of media devices, including mobile devices. In recent years, mobile news consumption has permeated individuals’ news consumption repertoires. The main purpose of this study is twofold: (a) gain insight in how mobile news outlets infiltrated the broader news media repertoires of mobile device owners and (b) understand in what circumstances mobile news is consumed within these news media repertoire…
(What) Can Journalism Studies Learn from Supervised Machine Learning
In recent years, scholars have explored the applicability of supervised machine learning (SML) within journalism studies. While such computational methods could be of added value to the field, the rationale for employing these supervised models harbors some assumptions that deserve further inspection. This paper seeks to specify under which conditions SML could be useful for journalism scholars and where the field stands in exploiting its potenti…
The triple articulation of media technologies in teenage media consumption
This study explores the meaning of teenagers’ media consumption in terms of identity formation and autonomy attainment. In domestication theory, media consumption is conceptualized as the interplay of both media object and content. However, in practical applications, the notion of object has usually been snowed under by contextual descriptions. In response, this article draws upon the concept of a triple articulation that, next to media text, sep…
Balancing Public and Private Value for the Digital Television Era
As the digital switchover is the result of the dynamic interplay between economic, social and political interests, this article reflects on the role of all stakeholders involved in the switch to digital television services. It aims to discuss the trade-off between public and private policy interests focussing on strategies for preparing the transition process and the digital take-off as well as on future opportunities that become available in the…
Gratifications and Seeding Behavior of Online Adolescents
Several studies indicate that only a small minority of Web 2.0 users actively participates, while the minority do not contribute at all. This article investigates whether a similar division applies for adolescents ' Internet behavior. Using Szuprowicz' (1995) typology of interactivity, we distinguish different types of user-generated content (UGC): media, narrative, and metadata UGC. Our results show a 20%-80% division between high-and low-freque…
Attracting the un-served audience
Digital television services not only provide promise for interactive services, but also for long tail-based business models in terms of tailor-made content. As the share of culture in total linear television programming is diminishing owing to the supremacy of audience rating concerns, digital television services could act as an alternative gateway to deliver culture to a wider audience. This article presents the results of a market pilot study u…

Smartphone Use and Academic Performance
To study the causal impact of smartphone use on academic performance, we collected – for the first time worldwide – longitudinal data on students’ smartphone use and educational performance. For three consecutive years, we surveyed all students attending classes in 11 different study programmes at two Belgian universities on general smartphone use and other drivers of academic achievement. These survey data were merged with the exam scores of the…
The chasm between having and using – Adoption versus use diffusion of iDTV in Flanders
The study of innovation has traditionally been characterized by two main paradigms: the ‘diffusion of innovations’ and the ‘domestication’ of innovations. They were originally considered as two distinct approaches with their own methods, tools and assumptions. However, recently an ‘interactionist’ stance has emerged, trying to combine the best of both worlds. This has resulted in research efforts combining insights from both traditions. Within th…

Player Identification in Online Games
This article proposes a scale for measuring player identification in massively multiplayer online games (MMOGs). Three dimensions have been derived from the literature, avatar identification, group identification, and game identification, whereby avatar identification is a second-order factor consisting of similarity identification, wishful identification, and embodied presence. Based on the results of a cross-sectional survey of 544 World of War…
Measuring Energy-Efficient Behavior in Households
In 2007, the European Council launched the 20/20/20 directive, which ambitions a reduction of greenhouse gas emissions by 20% compared to 1990, 20% of energy originating from renewables, and a 20% increase in energy efficiency by 2020. The energy efficiency aspect is extremely important in this directive, and important steps have been taken to obtain this goal, especially in building and electric appliance domains. Most residential energy users, …

Fear of Missing Out as a Predictor of Problematic Social Media Use and Phubbing Behavior among Flemish Adolescents
Fear-of-missing-out (FOMO) refers to feelings of anxiety that arise from the realization that you may be missing out on rewarding experiences that others are having. FOMO can be identified as an intra-personal trait that drives people to stay up to date of what other people are doing, among others on social media platforms. Drawing from the findings of a large-scale survey study among 2663 Flemish teenagers, this study explores the relationships …
