The Impact of Social Media on Adolescent Mental Health and Well-being: A Scoping Review
The pervasive influence of social media on modern society is undeniable, particularly for adolescents, who have integrated various platforms into their daily lives. This rapid expansion of social media has outpaced scientific understanding of its impact on adolescent mental health and well-being, creating a knowledge gap between public perception, often fueled by media reports, and scientific evidence. This scoping review aims to bridge this gap by analyzing existing research on social media’s effects on adolescent mental health, identifying key themes, core concepts, and crucial research gaps.
This review meticulously examined 79 peer-reviewed studies published between 2014 and 2020, encompassing both quantitative and qualitative research designs. The studies were identified through a systematic search across multiple databases, including Medline, Embase, PsycINFO, and others, using a combination of keywords related to adolescents, social media, and mental health. The included studies were predominantly quantitative and cross-sectional, conducted primarily in school settings, with a few utilizing longitudinal designs or incorporating data from home settings.
The results reveal a significant research focus on the negative aspects of mental health, with depression being the most frequently studied outcome. A substantial number of studies also examined general mental health or psychiatric problems, body dissatisfaction, anxiety, alcohol use, sleep disturbances, drug use, and self-harm/suicidal behavior. In contrast, studies exploring positive mental health outcomes, like well-being and happiness, were less common. This bias toward negative outcomes reflects a broader societal trend of focusing on the potential harms of social media, often fueled by media narratives and moral panic.
The review also identified inconsistencies in how social media use was measured. While some studies focused on specific platforms like Facebook, Instagram, or Twitter, others used broad measures of online communication without specifying platforms. The most common approach to measuring social media use was assessing the frequency and duration of use, often relying on self-reported data, which can be subject to recall bias and social desirability effects. Few studies examined specific online behaviors, motivations for using social media, or the individual’s mental state before engaging with social media. This lack of detailed measurement hinders a deeper understanding of the nuanced ways in which different types of social media use might impact mental health.
Furthermore, the review revealed a tendency for studies to implicitly assume a causal relationship between social media use and mental health problems, despite the predominantly cross-sectional nature of the research, which cannot establish causality. This implicit causation likely stems from the observed correlation between increased social media use and rising rates of mental health issues among adolescents, coupled with the prevailing negative narrative surrounding social media. This assumption, however, overlooks the potential for reverse causality (mental health problems influencing social media use) or the influence of confounding factors.
This review also highlights significant gaps in the current literature. There’s a clear need for more longitudinal studies to investigate the long-term effects of social media use and to explore potential bidirectional relationships between social media and mental health. Such studies could help disentangle correlational findings and provide insights into the direction of causality. Additionally, more qualitative studies are needed to understand the lived experiences of adolescents and their perspectives on the relationship between social media and mental health. These qualitative insights can provide a richer context for interpreting quantitative findings.
Another significant gap is the limited attention paid to the potential benefits of social media. While the review does include studies that examined well-being, there’s a need for more research explicitly focused on the positive aspects of social media use, such as social connection, community building, and access to information and support. Such research can contribute to a more balanced understanding of social media’s impact.
Finally, the review emphasizes the importance of considering individual factors, such as gender, ethnicity, socioeconomic status, and pre-existing mental health conditions, when studying the relationship between social media and mental health. These factors can moderate the effects of social media, and understanding their influence is crucial for developing effective interventions.
In conclusion, this scoping review provides a comprehensive overview of the existing research on social media and adolescent mental health and well-being. It reveals a complex and evolving landscape characterized by a predominant focus on negative outcomes, methodological limitations, and significant research gaps. Addressing these gaps through more longitudinal and qualitative research, investigations of positive effects, and consideration of individual factors is crucial for advancing our understanding of this important relationship and informing policies and interventions that support adolescent mental health in the digital age. Future research should also prioritize objective measurements of social media use and explore specific online behaviors, motivations, and contexts to gain a more nuanced understanding of how social media impacts adolescents’ lives.
