The key findings of this study revealed that medium users and high users of social media had higher probabilities of experiencing psychological health issues at 19.3% and 16.2% compared to lower users, respectively. Regarding the individual social network, Facebook emerged as the most detrimental, with 31.3% probability of psychological health problems among medium users and 51.9% among high users, followed by Snapchat users at 43.3%. Instagram and TikTok usage were also associated with approximately 15% probability of psychological health problems. Our data also revealed that adolescents exhibited various signs of social network addiction, such as tolerance, mood alteration, risk of relapse, withdrawal symptoms, and interference with daily activities, having probabilities ranging from 19.0–25.2% of experiencing psychosocial health problems. These associations were observed considering the role of several relevant covariates. Finally, we also noticed that the highest probabilities of having psychological health problems were identified in adolescents with high addictive behaviors when using social networks and the lowest in those with low addictive behaviors.
To the best of our knowledge, this is the first study to investigate these issues in the adolescent population from Spain, approaching separately the role of different social media platforms. Taken together, these findings underscore a concerning scenario regarding the use of social network and mental health of Spanish adolescents. The results suggest that harm to psychological well-being is evident even with moderate use of social networks, indicating that it is not solely high usage that is associated with a risk to adolescents' health. Previous literature has shown that excessive social network use (more than 3 hours a day) is linked to psychological distress and internalizing problems among adolescents [8, 38]. However, our findings suggest that even moderate use of social networks is associated with worse mental health, suggesting that the impact of social media on psychological well-being may be more pronounced than previously thought. On the other hand, our findings indicate that low usage of social networks is associated with a lower probability of experiencing psychological health issues, suggesting that abstaining from using social networks may prevent psychosocial health problems.
In this context, it is essential to consider the role of the different social networks, due to their individual characteristics. Each platform offers unique features and content, which can influence how adolescents engage with them and the potential impact on their psychological well-being [39]. We observed that Facebook and Snapchat were the social networks most strongly associated with psychological health problems. What is shown by existing literature is that, while it may be beneficial for some aspects like emotional support, self-expression, self-identity, and real-world relationships [40, 41], prolonged use of Facebook and Snapchat by adolescents is also associated with symptoms of anxiety and depression, loneliness, sleep problems, body image issues, and bullying [40, 42–45]. These adverse effects can be attributed to tendencies toward comparison and hopelessness, nighttime exposure to screens inhibiting the release of sleep hormones, instant propagation of negative comments, and the perception that by observing others' “exciting” lives, they are missing out on the chance to live their own [46, 47]. On the other hand, the psychological necessities of adolescents may motivate the search for content that will bring relief to their symptoms [48].
Another aspect identified was the addictive behaviors associated with social network use among adolescents and their relationship with psychosocial health problems. Each indicator of social media addiction presents unique implications for adolescent well-being. Tolerance, manifested as a desire to increase social media use, signifies a growing dependence on digital platforms for social interaction and validation, potentially leading to escalated addictive behaviors over time [49]. Similarly, mood alteration through social media use reflects the emotional impact of online interactions, suggesting that the immersive nature of social media platforms can influence adolescents' mood and overall psychological well-being [50]. Moreover, the risk of relapse into addiction after attempting to control use underscores the challenges teens face in regulating their online behavior, highlighting the dependence they develop on digital platforms for emotional support, social connection and continuous reward [51]. Additionally, interference with social and daily activities due to social media use disrupts teenagers' offline lives, exacerbating feelings of isolation and detachment from real-world interactions, ultimately compromising their overall functioning and well-being [52]. These findings underscore the multifaceted nature of social media addiction and its profound impact on various dimensions of adolescent psychosocial health.
Several mechanisms could explain the link between social media use and psychological health problems. Factors such as idealization of a perfect life, constant comparison, cyberbullying, body image comparisons, and disrupted sleep patterns due to late-night usage all play a role [53, 54]. Also, evidence indicates that social media use can lead to dopamine release in the brain, similar to other addictive behaviors. Dopamine is a neurotransmitter associated with pleasure and reward. When we engage in activities that we find pleasurable, such as receiving likes or comments on social media posts, dopamine is released in our brains, reinforcing the behavior and encouraging us to continue engaging in it [55, 56]. Another aspect involved is that excessive social media use can lead to dysregulation of dopamine pathways, resulting in individuals feeling compelled to check their social media accounts frequently, even when it interferes with other aspects of their lives such as work, sleep, or social interactions [56]. It is also speculated that this relationship may be bidirectional, meaning that having symptoms led to higher social media usage [48].
Regarding addiction to social network behavior predicting psychosocial health problems, the literature presents similar results. Aspects such as attention deficit hyperactivity disorder, anxiety, and depression are associated with social media dependency, demonstrating in some cases that the greater the use of social media, the more severe the symptoms [57, 58]. Sümen & Evgin, 2021 demonstrated that Turkish adolescents who were addicted to social media had a higher risk of developing various mental health issues, such as conduct problems, emotional issues, and issues with peers. Possible mechanisms for this relationship were also indicated, including the barrier that social networks create to establishing personal relationships with family and the environment; the use of social media to relieve undesirable mood states, as well as symptoms of stress and anxiety; and even social media as a mechanism for modulating neuroendocrine responses and the sympathetic nervous system in the face of a stressor event [57–59].
There are some limitations to consider in this study. First, the use of social network and psychosocial health were based on self-reports by adolescents, which could potentially lead to super estimation or underestimation of data, depending on memory, and may be affected by social desirability. Additionally, as social media usage patterns evolve rapidly, our data, while collected relatively recently, may not capture the most current trends and newest platforms. Finally, the sample was not representative, which can make it difficult to extrapolate the results. On the other hand, some important strengths of this study must be considered. Our study was composed of a representative group of adolescents from a region of Spain, which increases the generalizability of the findings to a wider population. Furthermore, the comprehensive nature of the study, which examined multiple social media platforms and their individual impact, offers crucial insights for developing targeted interventions and prevention strategies. Finally, we included in the analyses a large number of covariates, such as age, sex, socioeconomic status, sleep duration, physical activity, sedentary behavior, BMI, and adherence to the Mediterranean diet, thereby enhancing the validity of the present results.
In conclusion, adolescents who use social networks more frequently are more likely to experience psychological health problems compared to those who do not. Facebook emerged as the most detrimental, followed by Snapchat, Instagram, and TikTok. Our data also revealed that adolescents exhibit various signs of social network addiction and that the greater the addiction, the greater the psychosocial problems. Taken together, the findings of the present study have the potential to contribute to a more nuanced understanding of the complex relationship between technology use and adolescent well-being, with implications for both research and practice in the fields of psychology, education, and public health.
