Impact of social media use on self-esteem and body image among university students: a cross-sectional study

Project Abstract

This cross-sectional study investigates the relationship between social media use, self-esteem, and body image among university students, examining how patterns of engagement, perceived appearance-related pressures, and platform-specific features relate to psychological well-being. A stratified random sample of 600 undergraduate students (balanced by gender, age 18–25, diverse disciplines) completed an online survey comprising validated measures the Rosenberg Self-Esteem Scale, the Body Esteem Scale for Adults, and the Social Media Use Integration Scale, along with a custom module assessing time spent on platforms (Instagram, TikTok, Facebook, Twitter), passive scrolling, active posting, and exposure to appearance-focused content. Additional items captured demographic data, academic stress, sleep quality, and exercise frequency to account for confounding variables. Statistical analyses included descriptive statistics, multivariate linear regression, and structural equation modeling to test a mediation model wherein social comparison and appearance-related feedback mediate the link between social media use intensity and body image, while self-esteem serves as a potential moderator for the impact of negative feedback and appearance ideals. Results indicated that higher overall social media use was associated with lower body esteem (? = -0.28, p < 0.001) and lower self-esteem (? = -0.22, p < 0.001), with strongest effects among those engaging in frequent appearance-focused content and passive consumption. Mediation analyses revealed that social comparison significantly mediated the relationship between appearance-focused exposure and body image concerns (indirect effect ? = -0.15, 95% CI [-0.22, -0.09]), suggesting that comparing oneself to idealized images drives body dissatisfaction. Active posting and platform-specific differences yielded nuanced results Instagram and TikTok use showed stronger associations with body image disturbance than Facebook, potentially due to visual-centric content and algorithmic emphasis on aesthetic presentation. Sleep quality partially mediated the relationship between social media use and self-esteem, indicating that poorer sleep among heavy users contributes to diminished self-perception. Moderation analyses demonstrated that higher self-esteem buffered the adverse impact of negative feedback and appearance comparisons on body image, but did not fully mitigate it, indicating residual vulnerability among heavy users. Subgroup analyses by gender revealed that female students reported greater body image concerns in relation to appearance-focused exposure, while male students exhibited weaker but still significant associations. The study highlights critical psychosocial pathways linking digital environments to psychological well-being in young adults, underscoring the role of social comparison, platform design, and feedback dynamics. Practical implications include the need for digital literacy programs that promote mindful social media use, media literacy interventions to foster resilience against appearance ideals, and university-based mental health services that address body image and self-esteem in the context of contemporary online culture. Limitations include the cross-sectional design, reliance on self-report measures, and potential sampling bias toward students comfortable with online participation. Future research should explore longitudinal trajectories, causal mechanisms, and intervention effectiveness across diverse cultural contexts and academic disciplines.

Project Overview

What This Project Is About

---

A straightforward study that looks at how using social media influences how university students feel about themselves and their bodies. It explores whether more time on platforms like Instagram, TikTok, and Facebook relates to higher or lower self-esteem and how people view their body shape and size.

The Problem It Addresses

---

Many young adults report worries about their appearance and self-worth, and social media is a constant part of daily life. The project investigates whether exposure to idealized images and feedback from peers on social media contributes to negative body image or changes in self-esteem, filling gaps in how these factors interact in a real-world setting.

Objectives of the Project

---

1. Describe how much time students spend on major social media platforms.
2. Assess levels of self-esteem and body image among participants.
3. Examine the relationship between social media use and self-esteem.
4. Examine the relationship between social media use and body image concerns.
5. Identify other factors (like gender, age, or prior exposure to body- image content) that may influence these relationships.

What You Will Do Step by Step

---

1. Review simple background literature on social media, self-esteem, and body image.
2. Design a small survey measuring time on social media, self-esteem, and body image concerns.
3. Recruit volunteer participants from the university and obtain consent.
4. Collect survey responses and organize data into an easy-to-use format.
5. Check data for accuracy and summarize basic patterns.
6. Run simple statistics to explore associations (for example, correlation).
7. Interpret what the numbers might mean for real-life experiences.
8. Discuss limitations and practical implications for students and educators.

Expected Outcome

The project is expected to show whether higher social media use is linked to lower self-esteem or more body image concerns, or whether the relationships depend on other factors. The findings could inform campus wellbeing programs and media literacy efforts to help students engage with social media in healthier ways.
