Humanistic Studies and Social Researches

Abstract Background: The widespread adoption of social networking sites (SNSs) into the daily lives of teenagers marks a major sociotechnological shift of this century. As young people grow up immersed in digital technology, their journeys of self-discovery and self-evaluation increasingly occur within online spaces shaped by algorithms, rather than solely in face-to-face settings. This change requires a close look at how these platforms both influence and complicate core aspects of psychological and social development.
Objective: This narrative review brings together recent research (2015–2025) to examine the complex, and often opposing, effects of SNSs on how adolescents form their identity and develop self-esteem. It seeks to provide a detailed understanding of the processes, influencing factors, and two-way dynamics at play, moving beyond oversimplified cause-and-effect explanations.
Methods: A systematic search was performed across PubMed, PsycINFO, and Scopus databases for peer-reviewed articles published between 2015 and 2025. Key search terms included: "social media," "adolescent," "teen," "youth," "identity," "self-concept," "self-esteem," "social comparison," and "digital identity." The review included empirical studies (cross-sectional, longitudinal, experimental), systematic reviews, and important theoretical papers. Sources were selected based on relevance and methodological quality.
Results: Research reveals a dual role for SNSs, acting as both a catalyst and an obstacle to development. These platforms enable identity exploration through trying out different self-presentations and finding specialized communities, but they also risk fragmenting identity due to pressures to perform and seek external approval. Similarly, SNSs can strengthen self-esteem by providing social support and opportunities to showcase skills, yet they can also systematically weaken it by encouraging constant social comparison and reliance on quantified feedback (likes, followers). The ultimate impact depends heavily on individual differences, how platforms are used, specific platform designs, and the quality of a teenager's offline relationships.
Conclusion: The review frames SNSs as active "developmental environments" that shape how adolescents socialize, rather than seeing them as neutral tools. Future research should use methods like ecological momentary assessment to capture real-time experiences and investigate the role of content algorithms. Practical steps should focus not just on reducing screen time, but on building critical digital literacy skills and pushing for platform designs that are ethically informed by developmental psychology.

Abstract Background: Life satisfaction, a core evaluative component of subjective well-being, is inherently relative. Social comparison theory posits that individuals determine their own social and personal worth based on how they stack up against others. Despite six decades of research, a comprehensive synthesis of how different comparison processes, moderators, and modern digital contexts shape global life judgments is needed.
Objective: This review aims to systematically synthesize theoretical and empirical evidence on the role of social comparison in life satisfaction formation, identify key mechanisms and moderators, and highlight gaps for future research.
Methods: A narrative review methodology was employed. Scholarly databases (PubMed, PsycINFO, Web of Science) were searched for English-language articles and key texts from 1954 to 2025. Search terms included "social comparison," "life satisfaction," "subjective well-being," "reference group," and related constructs. Theoretical frameworks, landmark studies, and recent empirical findings were integrated.
Results: The review confirms social comparison as a fundamental, dual-pathway mechanism. Upward comparisons typically reduce life satisfaction through contrast effects but can increase it via inspiration (assimilation). Downward comparisons generally enhance satisfaction through contrast but can induce fear. Impact is moderated by individual differences (e.g., Neuroticism, Social Comparison Orientation), target similarity, and cultural context. The pervasive influence of social media, characterized by curated upward comparisons, is strongly associated with diminished life satisfaction.
Conclusion: Life satisfaction is profoundly constructed through comparative evaluation. The effect direction hinges on cognitive processes (assimilation/contrast), target selection, and dispositional traits. In the digital age, understanding and mitigating the negative impacts of maladaptive comparison, while harnessing its potential for motivation, is a critical public health concern. Future research must employ longitudinal designs and explore intervention strategies.
