A major study confirms a troubling link: as preteens spend more time on social media, their risk of depressive symptoms rises. This finding matters for Thai families, teachers, and policymakers aiming to safeguard young people’s mental health in a digital age.
Researchers from UCSF analyzed data from a large, long-term study of nearly 12,000 children, following them from ages 9–10 into early adolescence. They found that daily social media use increased from about seven minutes to 73 minutes over three years, while depressive symptoms rose by about 35 percent. Importantly, the study shows that greater social media engagement precedes increases in depressive symptoms, suggesting the online environment itself can influence mood, not just reflect existing struggles. In Thailand, where smartphone use among youth is widespread, these findings prompt urgent questions about digital wellbeing and support systems in schools and communities.
Experts emphasize the significance of distinguishing cause from effect in youth mental health research. Lead author and pediatric researcher at UCSF explained that while online platforms are not the sole cause of depression, they may contribute to its development when usage becomes excessive or harmful. The study was supported by the US National Institutes of Health and the Doris Duke Charitable Foundation, underscoring its rigorous design.
Separate analyses within the same group highlight a grave risk: cyberbullying more than doubles the likelihood of suicidal thoughts or attempts the following year. Youth who faced online harassment also showed higher tendencies toward risky behaviors, including increased marijuana and nicotine use, underscoring the broader health implications of a hostile online environment.
In Thailand, data from the Ministry of Digital Economy and Society shows smartphone penetration remains very high among adolescents, with many active on platforms such as Facebook, Instagram, TikTok, and LINE. Social media helps maintain friendships and community, yet it can blur the line between connection and overexposure. The rapid shift to online learning during the pandemic has intensified concerns about digital wellbeing among Thai students, educators, and parents.
Mental health professionals in Bangkok echo these concerns. They note a rise in depressive and anxious symptoms linked to social media pressures, cyberbullying, and disrupted sleep. Cultural stigma around mental illness can delay treatment, making early intervention all the more important.
Thai families often balance strong family ties with evolving tech skills gaps across generations. Parents may feel unsure how to guide their children’s online activities while maintaining open dialogue. In response, many urban Thai schools are introducing digital literacy and mental health curricula designed to build resilience and teach responsible online behavior.
Experts worldwide advocate a multi-pronged approach to protect youth. Parents are encouraged to establish structured media use plans that include screen-free times, especially during meals and before bed, and to foster open, non-judgmental conversations about online experiences. Simply telling children to “get off your phone” is ineffective; modeling healthy habits and co-creating household rules can make a real difference. When concerns arise, seeking professional support early can prevent more serious mental health issues later.
Looking ahead, Thai authorities signal interest in nationwide policies that address digital wellbeing in schools. Initiatives may include teacher training on cyberbullying prevention, digital detox programs, and early detection of depression and anxiety among students.
For Thai readers, the takeaway is clear: social media is deeply embedded in daily life, offering both connection and risk. Parents and educators should collaborate to set healthy boundaries, teach online literacy, and create safe spaces for children to discuss their digital experiences. Early, proactive engagement with mental health professionals can protect youths from more serious challenges down the road.
