Against a backdrop of rapidly evolving digital landscapes, a new study has illuminated the complex interplay between shyness and the burgeoning phenomenon of short video addiction, particularly among college students. Research published in Frontiers in Psychology reveals that while shyness directly contributes to compulsive short video consumption, its influence is also significantly mediated by social support and basic psychological needs, operating in a sequential chain. This comprehensive investigation, conducted with 1,513 students at a college in western China, offers critical insights into the psychological mechanisms driving this prevalent form of internet overuse and suggests targeted strategies for prevention and intervention. Shyness: A Growing Concern in the Digital Age Shyness, characterized by discomfort and inhibition in social situations and a fear of negative evaluation, is increasingly recognized as a significant personality trait impacting various aspects of an individual’s life. In contemporary society, where digital interactions often supplement or even substitute face-to-face engagement, shyness can present unique challenges. College students, navigating a period of significant personal and academic development, are particularly susceptible to these influences. The proliferation of short video platforms, which now represent the leading online application in China with over 1.068 billion users, has introduced a new dimension to this issue. These platforms, with their fragmented, diverse, and highly interactive content, resonate deeply with younger demographics. However, their addictive potential is a growing concern, leading to compulsive use, psychological cravings, and behavioral dependencies that can impair social functioning, sleep patterns, and overall well-being. Unraveling the Mediating Pathways The study aimed to dissect the mechanisms through which shyness influences short video addiction, incorporating the roles of social support and basic psychological needs. Using a convenience sampling method, researchers administered a battery of validated scales, including the Shyness Scale, Short Video Addiction Scale, Social Support Rating Scale, and Basic Psychological Needs Scale. Analysis revealed a significant positive correlation between shyness and short video addiction. This direct link, validating Hypothesis 1, suggests that shy individuals are inherently more prone to developing addictive behaviors related to short video consumption. This aligns with established theories positing that personality traits can directly influence behavioral outcomes. Shy individuals often experience heightened negative emotions such as anxiety and fear in social contexts, making them more likely to seek solace or escape in the easily accessible and engaging world of short videos. Furthermore, the user-friendly design and instant gratification offered by these platforms can exacerbate this tendency, particularly for those with poorer self-control. Beyond the direct effect, the research uncovered crucial indirect pathways. Social support was found to act as a significant mediator, confirming Hypothesis 2. Shy individuals often struggle with establishing and maintaining robust interpersonal relationships, leading to lower perceived social support. This deficit in real-world connections can leave them vulnerable, driving them to seek compensatory satisfaction through online platforms. The cognitive-behavioral model suggests that insufficient social support can foster maladaptive cognitions, prompting compulsive internet use as a coping mechanism. In the context of Chinese universities, where dormitory life and peer relationships are paramount, a lack of strong social connections can be particularly detrimental. Further investigation highlighted the mediating role of basic psychological needs, supporting Hypothesis 3. According to Self-Determination Theory, the fulfillment of needs for autonomy, competence, and relatedness is essential for psychological well-being and self-regulation. Shy individuals, due to their reticence and fear of negative impression, often find it challenging to satisfy these fundamental needs in real-world interactions. The study found that when these basic psychological needs are thwarted, individuals are more susceptible to the compensatory appeal of short video platforms. The rich information and immediate feedback offered by these platforms can provide a rapid, albeit superficial, sense of fulfillment, leading to immersion and potentially addiction. The Chain Reaction: Social Support and Psychological Needs in Sequence The most compelling finding of the study, however, is the identification of a chain mediating role played by social support and basic psychological needs, confirming Hypothesis 4. This sequential pathway illustrates a progressive process: shyness leads to diminished social support, which in turn frustrates basic psychological needs. This unmet psychological need then drives individuals towards short video addiction. This serial mediation model offers a nuanced understanding of how personality traits translate into behavioral patterns. It demonstrates that environmental factors, such as social support, can exert their influence on behavior by first impacting intrinsic psychological states, such as the satisfaction of basic needs. This finding provides robust empirical support for the core tenets of Self-Determination Theory, underscoring the interconnectedness of social context, psychological well-being, and behavioral outcomes. The analysis revealed that while the direct effect of shyness on short video addiction accounted for a substantial portion of the total effect (61.76%), the indirect pathways collectively explained 38.24%. Within these indirect pathways, the chain mediation through social support and basic psychological needs contributed significantly (14.16% of the total effect), emphasizing its critical role. This suggests that interventions targeting both environmental and psychological factors are essential for a comprehensive approach to addressing short video addiction. Implications for Intervention and Prevention The findings of this study carry significant theoretical and practical implications. Theoretically, it enriches the literature on technology addiction by extending the application of Self-Determination Theory to the specific context of short video addiction and demonstrating how need frustration can link personality traits to addictive behaviors. Practically, the research points towards a multi-pronged strategy for intervention and prevention. For shy individuals, who are at higher risk due to weaker social support networks and subsequent frustration of their basic psychological needs, interventions should focus on two key areas: Strengthening Social Support: This can involve structured group activities, peer mentoring programs, and social skills training designed to help shy individuals build meaningful connections and enhance their perceived social support. Universities and educational institutions can play a pivotal role in facilitating these initiatives. Satisfying Basic Psychological Needs: Creating supportive environments through family counseling, teacher-student mentoring, and accessible online support communities can help shy individuals develop trust and transform negative beliefs about social relationships. By fostering environments that genuinely support autonomy, competence, and relatedness, the compensatory appeal of algorithm-driven short video platforms can be significantly diminished. Furthermore, addressing shyness itself through psychological interventions could tackle the root cause of the issue, offering a more foundational approach to reducing addiction risk. Limitations and Future Directions While this study provides valuable insights, it is important to acknowledge its limitations. The cross-sectional design precludes definitive causal inferences, highlighting the need for longitudinal studies and experimental interventions to validate the proposed pathways. The reliance on self-reported data, while common in psychological research, carries the risk of social desirability bias. Future research could benefit from employing multi-method data collection, including behavioral observations or peer reports, to mitigate this potential bias. Additionally, the study’s focus on college students limits the generalizability of its findings. Future research should aim to replicate this model across more diverse populations to assess its broader applicability. Exploring additional mediating factors, such as maladaptive cognitions or emotion regulation strategies, could further deepen our understanding of the complex relationship between shyness and short video addiction. Conclusion In conclusion, this study offers a compelling narrative of how shyness, a common personality trait, can lead to short video addiction through a cascade of psychological processes. The direct link between shyness and addictive behavior is amplified by the indirect effects of diminished social support and unmet basic psychological needs, operating in a sequential manner. By understanding these intricate connections, educators, mental health professionals, and policymakers can develop more effective strategies to support vulnerable students, fostering healthier digital habits and promoting overall well-being in an increasingly interconnected world. The research underscores the critical importance of nurturing supportive social environments and ensuring the fulfillment of fundamental psychological needs as bulwarks against the pervasive allure of digital distractions.
