Teens' friends can increase mental health risk

Key Points:

• A Finnish study published in JAMA Psychiatry found that teenagers are more likely to develop depression or anxiety if their peers have diagnosed mental disorders or genetic predispositions, with the strongest associations seen in high school settings.
• Emotional contagion, where emotions are passed between individuals, may contribute to this effect, as teens often mirror the feelings and behaviors of their friends, potentially triggering genetic vulnerabilities to mental health issues.
• Normalization of mental health struggles among peers can encourage teens to recognize and discuss their own challenges, but experts emphasize the importance of seeking professional help rather than relying solely on peer support or online information.
• The study highlights the critical role of school environments in mental health, suggesting that stressors like academic pressure and bullying contribute to the spread of anxiety and depression, underscoring the need for school-based mental health interventions.
• Experts caution against social isolation despite the potential for mental health issues to "spread," as isolation can worsen depression, and they urge parents and adults to support teens by monitoring their well-being and encouraging open communication.
