This paper reviews screen time and its role within school-based behavioural interventions targeting adolescents between the years 2007 and 2019. A systematic literature review following PRISMA guidelines was conducted across five major databases to identify interventions targeting screen time—in addition to TV/DVD viewing. The review identified a total of 30 papers analysing 15 studies across 16 countries aiming at addressing reduction of recreational screen time (internet use and gaming) in addition to television/DVD viewing. All of the interventions focused exclusively on behaviour change, targeting in the majority both reduction of sedentary behaviours along with strategies to increase physical activity levels. A mix of intervention effects were found in the reviewed studies. Findings suggest aiming only for reduction in time spent on screen-based behaviour within intervent...

Extensive research has been conducted with regard to psychosocial correlates and comorbidity, less so for the developmental mechanisms and the processes leading to the disorder. The association between family factors, personality traits, and gaming has been studied independently but not in combination. To fill this gap in knowledge, this study examined (a) the association between parental acceptance–rejection theory and Internet gaming disorder (IGD) and (b) the mediating and moderating effect of core self-evaluations (CSE), a personality construct, on the aforementioned variables. Methods The study was quantitative and involved young adults members of online gaming communities (N = 225). Results The results showed that parental rejection is associated with the occurrence of IGD, only through the mediat...

Given the arguably alarming prevalence rates worldwide and the increasingly problematic use of gaming and social media, the need for an integration of prevention efforts appears to be timely. The aim of this systematic literature review is (i) to identify school-based prevention programmes or protocols for Internet Addiction targeting adolescents within the school context and to examine the programmes' effectiveness, and (ii) to highlight strengths, limitations, and best practices to inform the design of new initiatives, by capitalizing on these studies' recommendations. The findings of the reviewed studies to date presented mixed outcomes and are in need of further empirical evidence. The current review identified the following needs to be addressed in future designs to: (i) define the clinical status of Internet Ad...

A ten-day online randomized controlled trial with the use of smartphone apps, engaging participants in mindfulness exercises, self-monitoring and mood tracking, was implemented amongst UK university students (n = 143). Participants were asked to complete online pre- and post-intervention assessments. Results indicated high effect sizes in reduction of smartphone distraction and improvement scores on a number of self-reported secondary psychological outcomes. The intervention was not effective in reducing habitual behaviours, nomophobia, or time spent on social media. Mediation analyses demonstrated that: (i) emotional self-awareness but not mindful attention mediated the relationship between intervention effects and smartphone distraction, and (ii) online vigilance mediated the relationship between s...

However, the underlying psychological mechanisms of engagement have not been adequately addressed. The present study examined adolescents’ psychological processes as these develop in their everyday interactions via social media. The sample comprised six focus groups with 42 adolescents from UK-based schools. Data were analyzed using constructivist grounded theory. The resulting concepts related to individual, social, and structurally related processes, highlighting a synergy between the processes underlying use and a gradual reduction of control as individual, social, and structurally led processes emerge, conceptualized as the ‘control model’ of social media engagement. The findings highlight a controlling aspect in engagement and a dynamic interplay between the processes as mutually determining the quality and the intensity of the interaction. Recommendations are provided for exam...

Parents are ambivalent about their mediating role. However, problematic aspects of adolescent online use have not been adequately addressed in education. The present study investigated parental perceptions of intervention needs within schools to prevent excessive/problematic use, enhance parent–child communication, and reduce family conflicts. Nine interviews with parents of adolescents residing in the UK were carried out and analyzed utilizing thematic analysis. Three main themes emerged as parental proposals: (i) schools as digital education providers and prevention hubs, (ii) provision of mental health literacy to raise awareness, resolve ambiguity regarding impacts and mitigate excessive use and impacts, and (iii) psychoeducation and upskilling. The third theme related to impacts from time spent on screens (time displacement), content-related impacts, and context-related i...

However, evidence on how teachers may best support media literacy and emotional wellbeing is lacking. The present study explored perceptions of adolescent online engagement and recommendations of how schools could prevent the experience of online harms during adolescence through qualitative interviews with teachers (N = 9, Mage = 39.2 years, SD = 7.74). Results were analysed using thematic analysis and provided the following themes in terms of recommendations for online harms: i) schools in transition and redefining expectations, ii) a modular approach to media and emotional literacy, iii) media and emotional literacy teacher training, and iv) encourage dialogue and foster psychosocial skills. Psychosocial skills were further analysed...

However, research providing a comprehensive and triangulated stakeholder perspective of perceived harms is lacking. How are adolescent online harms experienced and conceptualized by students, parents, and teachers? The present study comprised part of a qualitative needs assessment investigation with the use of focus groups and individual interviews among key stakeholder groups assessing perceived impacts with a focus on the negative consequences and perceived harms. The study’s sample consisted of students (N = 42, Mage = 13.5, SD = 2.3), parents (N = 9, Mage = 37, SD = 5.6) and teachers (N = 9, Mage = 34, SD = 4.9) from the UK. Data were analysed with thematic analysis. Findings focused primarily on social media use impacts and indicated that processes underlying impacts experienced by adolescents may be conceptualized on a ...

Within the attention economy perspective, distraction is increasingly associated with digital technology use, performance impairments and interference with higher-order cognitive processes. Research on smartphone distraction and its association with problematic smartphone use is still scarce and there is no available psychometric assessment tool to assess this cognitive and emotive process parsimoniously.Method: The present study reports the development and evaluation of the psychometric properties of the Smartphone Distraction Scale (SDS) through exploratory and confirmatory factor analysis, construct validity, gender invariance, and latent mean differences. The study was conducted in a sample of British university students (N = 1,001; M = 21.10 years, SD = 2.77).Results: The 16-item SDS was best conceptualized in a four-factor model solution comprising attention impulsivenes...
