Social Media Use and Young People’s Mental Health: A Quantitative Social Science Approach

Research project description

A PhD position is available at the Department of Sociology from Universitat Autònoma de Barcelona (UAB) within the Centre for Demographic Studies, in collaboration with Trinity College Dublin (TCD) within the Trinity Centre for Global Health. The PhD will be supervised by Pablo Gracia (UAB) and Alina Cosma (TCD). We are looking for a highly motivated candidate with outstanding skills in social research and quantitative methods to investigate Social Media Use and Young People’s Mental Health.

Digital technologies are an integral part of adolescents’ mental health linked to different opportunities and risks. While several studies found that adolescent screen time corre-lates to poorer mental health (Kelly et al. 2018; Twenge et al. 2018), studies indicate that such associations largely depend on the context and type of social media engagement, as well as on methodological design (Bohnert & Gracia, 2023; Livingstone et al., 2020; Orben & Przybylski, 2019; Valkenburg et al., 2022). Overall, the mechanisms linking so-cial media use to young people’s mental health remain unclear. We need innovative methodological approaches to examine heterogeneous and underlying mechanisms connecting social media use to young people’s mental health. This project will combine innovative quantitative approaches from sociology, demography, psychology and public health to address the following questions:

1. How has the expansion of social media impacted young people’s mental health across different sociodemographic groups and societies?

2. What are the causal mechanisms linking social media use to mental health from childhood to late adolescence?

The project will involve high-quality doctoral supervision from Autonomous University of Barcelona (in the disciplines of Sociology and Population) and Trinity College Dublin (i.e., in the disciplines of Psychology and Global Health). The PhD project will apply an inno-vative transdisciplinary approach using advanced quantitative methodologies applied to high-quality population-level data, such as longitudinal methodologies, computational methods, multi-level modelling, and causal inference designs.

The successful candidate will be enrolled in the PhD Sociology doctoral program at the Universitat Autònoma de Barcelona (UAB) in the framework of the TOUCH project. TOUCH (“Towards the next generatiOn of excellent yoUng doctoral researchers on mental health by developing an intersectoral & transdisciplinary approaCH”) is a new excellent doctoral programme co-funded by the Marie Skłodowska-Curie (MSCA) Ac-tions of the European Commission and led by the UAB for the recruitment and training of 24 doctoral candidates in the field of mental health and wellbeing.

Academic background / Skills

The candidates must fulfil the following eligibility criteria from the EC: Mobility rule: candidates must not have resided or carried out their main activity (work, studies, etc.) in Spain for more than 12 months in the 36 months immediately preceding the deadline for the programme call. Experience rule: researchers must be doctoral candidates at the date of recruitment, i.e. not already in possession of a doctoral degree at the deadline of the open calls. Researchers who have successfully defended their doctoral thesis but have not yet formally awarded the doctoral degree will not be considered eligible. Candidates must hold a degree that allows admission to the official doctoral programme at UAB.

Additional requirements for a stronger application are:

• Background in relevant social science discipline (e.g., sociology, demography, psychology, public health, economics, human development, neuroscience);
• Excellent academic record to date;
• Exceptional skills in quantitative methods and advanced statistical modelling (e.g., longitudinal methods, structural equation modelling, multi-level methods, causal inference designs);
• Strong potential to provide novel scientific understandings of the links between social media use and young people’s mental health;
• High proficiency in relevant statistical software (e.g., R, Stata, Python);
• Willingness to innovate using pioneering and interdisciplinary quantitative and computational methods;
• Excellent written and verbal skills in English language;
• Ambition and ability to produce and publish high-quality research in social sciences;
• Ability to work independently and as part of a team.

Research group/s description

The two supervisors are leading experts in the research field of this PhD project.

Prof. Pablo Gracia (main supervisor) leads a team on “Families, Well-Being and Inequalities” within the larger DEMFAM group from the Centre for Demographic Studies. Prof. Gracia is currently the lead PI of the DIGINEQ project, funded by the European Research Coun-cil (CoG) (2024-2029), in which he supervises multiple PhDs and Postdocs who examine how social media use links to disparities and inequalities in adolescent well-being and mental health.

Dr. Alina Cosma (co-supervisor) leads a research group in Psychology and Global Health at Trinity College Dublin and has extensive experience in designing and managing cross-national school health surveys focused on adolescent health. Her re-search spans a variety of topics, including time trends and predictors of change in ado-lescent mental health (from within-country and cross-country), as well as the social and structural determinants of adolescent well-being.
