The Effectiveness of an Internet-Based Intervention With Peer Support for the Mental Health of Youths: A Randomized Controlled Trial

Over the past decade, mental health issues have become increasingly prevalent among young people. Approximately 14% of adolescents aged 10-19 years globally suffer from conditions like depression and anxiety. This is concerning because adolescence is a critical period for development, and these mental health problems can have long-term consequences on various aspects of their lives, including relationships, education, and work.

The mental health of young people (15-24) is a significant global concern, affecting one in five individuals within this age group and representing the largest burden of illness. Moreover, the impact of mental health problems during adolescence can extend into adulthood, affecting physical and mental well-being and limiting opportunities for a fulfilling life.

According to the World Health Organization (WHO), mental health and psychosocial well-being are essential for youth's human potential and rights. However, the COVID-19 pandemic has exacerbated mental health problems among adolescents, leading to disruptions in critical mental health services in many countries. Studies have shown that the pandemic has resulted in increased depression, anxiety, stress, and sleep disorders among young people. Additionally, the previously mentioned conditions faced by adolescents have worsened to the point of mental disorders and suicide attempts.

The impact of the pandemic on youths' mental health has drawn global attention and highlights the urgency of intervening in their mental well-being. Stressors among young people primarily come from academics, employment, relationships, appearance, finances, etc. The lack of effective coping strategies and emotional regulation further exacerbate physical health symptoms and negative consequences. Unfortunately, a significant number of young people experiencing mental health problems do not seek professional help, primarily due to denial, embarrassment, lack of time, and stigma. They often turn to informal resources such as family, friends, books, or counseling websites, with uncertain effectiveness. Long waiting lists for psychological services add to the dilemma. Therefore, it is crucial to help youths overcome these barriers when providing support services.

Currently, access to cost-effective and accessible mental health services remains challenging for young people. In addition to counseling and psychiatric services, peer support has emerged as a novel resource for young people seeking help. Peer support involves social and emotional support from individuals with similar experiences. Research suggests that peer support is an accessible, affordable, and easily implemented mental health resource. Involving peer supporters in mental health services can promote recovery and has positive effects on depressive symptoms, anxiety, psychological distress, self-esteem, self-efficacy, and self-management. However, there is a lack of research on the development and implementation of peer-support based interventions for adolescents with psychological problems. This study aims to address this gap.
