Social media use and self-injurious thoughts and behaviors: A systematic review and meta-analysis.

The relationship between social media and self-esteem is complex, as studies tend to find a mixed pattern of relationships and meta-analyses tend to find small, albeit significant, magnitudes of statistical effects. One explanation is that social media use does not affect self-esteem for the majority of users, while small minorities experience either positive or negative effects, as evidenced by recent research calculating person-specific within-person effects. This suggests that the true relationship between social media use and self-esteem is person-specific and based on individual susceptibilities and uses. In recognition of these advancements, we review recent empirical studies considering differential uses and moderating variables in the social media-self-esteem relationship, and conclude by discussing opportunities for future social media effects research. 

Social media and self-esteem.

In this theoretical review paper, we provide a developmental–sociocultural framework for the role of social media (SM) in adolescent girls’ body image concerns, and in turn, depressive symptoms and disordered eating. We propose that the features of SM (e.g., idealized images of peers, quantifiable feedback) intersect with adolescent developmental factors (e.g., salience of peer relationships) and sociocultural gender socialization processes (e.g., societal over-emphasis on girls’ and women’s physical appearance) to create the “perfect storm” for exacerbating girls’ body image concerns. We argue that, ultimately, body image concerns may be a key mechanism underlying associations between adolescent girls’ SM use and mental health. In the context of proposing this framework, we provide empirical evidence for how SM may increase adolescent girls’ body image concerns through heightening their focus on (1) other people’s physical appearance (e.g., through exposure to idealized images of peers, celebrities, and SM influencers; quantifiable indicators of approval); and (2) their own appearance (e.g., through appearance-related SM consciousness; exposure to idealized self-images; encouraging over-valuing of appearance; and peer approval of photos/videos). Our framework highlights new avenues for future research on adolescent girls’ SM use and mental health, which recognize the central role of body image.

The Perfect Storm: A Developmental–Sociocultural Framework for the Role of Social Media in Adolescent Girls’ Body Image Concerns and Mental Health

There has been a notable increase in social media and Internet use over recent decades, not only for social interaction or entertainment, but also for working and meeting tools, as seen during the COVID-19 pandemic. A relationship between this usage and the development of mental illness is frequently hypothesized, but a few studies have empirical findings. This study is a systematic review of the relationship between social media use and depression or anxiety. Our Medline search yielded 1,747 papers. Our study found a strong and often bidirectional relationship between social media use and depression or anxiety. This relationship was frequently related to problematic social media use. No definite linear relationship was found between time spent using social media and depressive or anxious symptoms, but usually, the longer the time spent in that activity, the worse the outcomes. Factors related to problematic social media use were often different for men and women. Other variables may also play a role, such as nighttime-specific use, emotional involvement, and whether the individual behaves as an active or passive user. Evidence from this review provides a solid base for recommending cautious use of social media. Intense use and unhealthy habits, evidenced by addiction symptoms, may be problematic in less resilient individuals.

Problematic Social Media Use and Its Relationship with Depression or Anxiety: A Systematic Review

Adolescent depression is a worldwide public health concern and has contributed to significant socioeconomic burden. Investigating the association between time spent on social media (TSSM) and depression may provide guidance toward the prevention and intervention of adolescent depression. However, related literature reported mixed findings in terms of the relationship between TSSM and depression in adolescents. Hence, we conducted a comprehensive dose–response meta-analysis to clarify this issue. We conducted a systematic title/abstract and topic search of the relative terms in Web of Science, PubMed, PsycINFO databases through 9 January 2022. Odd ratios (ORs) were used to examine the pooled effect size of the association between TSSM and risk of depression. Dose–response analysis was evaluated by a generalized least squares trend estimation. Twenty-one cross-sectional studies and five longitudinal studies including a total of 55,340 participants were included. Overall, more TSSM was significantly associated with a higher risk of depression symptoms (OR = 1.60, 95%CI: 1.45 to 1.75) with high heterogeneity (Q(29) = 105.9, p < 0.001; I2 = 72.6%). The association was stronger for adolescent girls (OR = 1.72, 95%CI: 1.41 to 2.09) than boys (OR = 1.20, 95%CI: 1.05 to 1.37). Five studies with seven reports were included in dose–response analysis. There was a linear dose–response association of TSSM and risk of depression. The risk of depression increased by 13% (OR = 1.13, 95%CI: 1.09 to 1.17, p < 0.001) for each hour increase in social media use in adolescents. TSSM is associated with depression in a linear dose–response and gender-specific manner, which suggests the need for better monitoring of adolescent social media use. However, motivation, content, and engagement on and exposure to social media use may also be important contributing factors, making it necessary to interpret the current findings with caution. Therefore, further research is required to clarify not only the causal link between TSSM and depression by randomized control studies but also the influence of other factors, such as active vs. passive social media use or different types of engagement or environments in which social media is used.

Time Spent on Social Media and Risk of Depression in Adolescents: A Dose–Response Meta-Analysis

Previous research on associations between screen media use and mental health produced mixed findings, possibly because studies have not examined screen activities separately or accounted for gender differences. We sought to examine associations between different types of screen activities (social media, internet, gaming, and TV) and mental health indicators separately for boys and girls.
 We drew from a nationally representative sample of 13–15-year-old adolescents in the UK (n = 11,427) asking about hours per day spent on specific screen media activities and four mental health indicators: self-harm behavior, depressive symptoms, life satisfaction, and self-esteem.
 Hours spent on social media and Internet use were more strongly associated with self-harm behaviors, depressive symptoms, low life satisfaction, and low self-esteem than hours spent on electronic gaming and TV watching. Girls generally demonstrated stronger associations between screen media time and mental health indicators than boys (e.g., heavy Internet users were 166% more likely to have clinically relevant levels of depressive symptoms than low users among girls, compared to 75% more likely among boys). Thus, not all screen time is created equal; social media and Internet use among adolescent girls are the most strongly associated with compromised mental health. Future research should examine different screen media activities and boys and girls separately where possible. Practitioners should be aware that some types of screen time are more likely to be linked to mental health issues than others.

Not all screen time is created equal: associations with mental health vary by activity and gender

Screen media use is associated with mental health problems among adolescents. However, few studies have examined screen media use using contemporaneous time diaries (rather than retrospective reports), compared associations across specific screen media activities or by gender, or examined associations with self-harm behaviors. Participants were 13- to 15-year-old adolescents completing time diaries (n = 4,252) for one weekday and one weekend day in the 2015 administration of the Millennium Cohort Study, a nationally representative birth cohort study of UK adolescents. Participants also completed a measure of depressive symptoms and reported whether they had engaged in self-harm in the last year. Girls who spent 2 + hrs/day, compared to < 2 h/day, on digital media were more likely to self-harm (for social media use, adjusted relative risk [ARR] for self-harm = 1.46, 95% CI = 1.17, 1.82; for internet use, ARR = 1.80 [1.20, 2.70]). Girls spending more time on digital media were also more likely to be depressed (for social media, ARR = 1.29 [1.03, 1.63]; for internet use, ARR = 1.75 [1.19, 2.59]). Associations with gaming, texting/e-mailing, and TV/video watching among girls were mostly not significant. Associations for boys were mostly not significant. Girls who use digital media (especially social media and the internet) more hrs/day are more likely to have clinically significant levels of depressive symptoms and prior history of self-harm, though gaming, texting/e-mailing, and TV/video watching showed few associations. Screen media use was mostly not significantly associated with self-harm or depression among boys.
