  • Is zero effect really evidence of no effect? Introducing an outcomes balance perspective

    Open AccessHannah K Jarman, Shay‐akil Mclean et al.ARTICLEBody Image2026

    The influence of social media on body image has been extensively studied over recent years, yet findings are often inconsistent, with many studies reporting small or negligible effects. Such inconsistencies have raised important theoretical and methodological questions about what null effects truly mean. Using social media and body image research as an exemplar, this paper explores the meaning of null effects in the association between these cons…

  • Selfies and body dissatisfaction

    Open AccessHannah K Jarman, Ann RousseauARTICLENew Media & Society2025References: 10

    Selfies are frequently used among adolescents. Yet little is known about how selfies relate to body dissatisfaction over time and the mechanisms involved. The present study examined the longitudinal relationships between selfies (i.e. taking, manipulating, investing in and posting) and body dissatisfaction via sociocultural mediators; thin-ideal internalisation and comparisons. Adolescents ( N = 573; M age = 15.38, SD = 1.34; 68.2% female) comple…

  • Assessing the Temporal Dynamics in Self-Regulated Learning Constructs as Predictors of Engagement in a Digital Health Intervention

    Open AccessClaudia Liu, Matthew Fuller-Tyszkiewicz et al.ARTICLEBehavior Therapy2025References: 38

    The promise of self-guided digital health interventions (DHIs) is consistently hampered by their poor engagement. While past research has identified various predictors of engagement, effect sizes have been small, and many have failed to replicate across studies. This poor predictive performance may, in part, be due to the field's overreliance on predictor assessments at pre-intervention (i.e., at baseline), which overlooks the possibility that th…

  • Investigating bidirectional relationships between Instagram “addiction” and eating disorder symptoms

    Open AccessMariel Messer, Claudia Liu et al.ARTICLEEating Behaviors2025References: 28

    BACKGROUND: Social media use has been implicated in the development and maintenance of eating disorder (ED) symptoms, yet most existing research has focused on general social media engagement rather than addictive patterns of use. This study expands that work by examining Instagram-a widely used social media platform-and the role of Instagram addiction, defined as a compulsive and dysregulated pattern of engagement, in ED symptoms. Additionally, …

  • Sexting Among Australian Adolescents

    Open AccessDominika Howard, Hannah K Jarman et al.ARTICLEJournal of Youth and Adolescence2023References: 58

    Although consensual sending of sexts between adolescents is considered developmentally appropriate, it may also entail a range of negative consequences. Current sexting research lacks a comprehensive theoretical framework identifying a range of risk and protective factors underpinning adolescent consensual sending of sexts across individual, interpersonal, and distal levels. Further, there is a lack of systematic evaluation of how the importance …

  • Social Media Use and Body Dissatisfaction in Adolescents

    Open AccessAn Vuong, An T Vuong et al.ARTICLEInternational Journal of…2021

    Internalisation of appearance ideals moderates the relationship between exposure to media images and body dissatisfaction. To date, the role of thin- and muscular-ideal internalisation in the context of social media remains under explored, particularly for boys. As such, we aimed to explore how social media use (Instagram and Snapchat) was related to body dissatisfaction, and whether thin- and muscular-ideal internalisation would moderate this re…

  • Direct and indirect relationships between social media use and body satisfaction

    Open AccessHannah K Jarman, Shay‐akil Mclean et al.ARTICLENew Media & Society2021Cited by: 2References: 8

    Cross-sectional research suggests a small, inverse association between social media use and body satisfaction. However, less is known regarding prospective, bidirectional, or mediating effects. In line with sociocultural theory, this study used a three-wave design to examine direct and indirect effects between social media use and body satisfaction, via thin-ideal and muscular-ideal internalisation and social comparisons. Adolescents ( n = 1911; …

  • More than Just Child’s Play

    Open AccessAmy Slater, Emma Halliwell et al.ARTICLEJournal of Youth and Adolescence2017Cited by: 2References: 72

    In recent years, elements of the modern environment (such as television, Internet, toys and clothes) have been criticized for having an increasingly sexualized or appearance focus, which has been suggested to be detrimental to girls' development. The current study examined the impact of an appearance-focused Internet game on young girls' body image and career cognitions and aspirations. Eighty British girls aged 8-9 years were randomly assigned t…
