Friendship Quality and Adolescent Mental Health

Friendship quality during adolescence encompasses the degree of emotional support, intimacy, trust, conflict resolution and mutual understanding between peers. High-quality friendships serve as a critical buffer against stressors such as academic pressure, social exclusion and family discord, promoting resilience and reducing symptoms of anxiety and depression. Conversely, maladaptive patterns within friendships—such as excessive co-rumination or unbalanced exchanges of support—can intensify focus on distress, undermining psychological well-being. Gender differences emerge, with girls often engaging in more intimate self-disclosure and co-rumination, while boys may prioritise shared activities and problem-solving. Digital technologies have altered the landscape, providing new opportunities for connection but also introducing risks of online dependency and unmoderated exposure to peers’ negativity. Socio-cultural factors further shape friendship processes, with varying norms around emotional expression and help-seeking. Interventions aiming to enhance adaptive support and emotional regulation within friendships show promise in preventing internalising symptoms. Understanding the dynamic interplay between positive and negative aspects of adolescent friendships is essential for informing school-based programmes, clinical practices and public-health initiatives designed to foster mental health during this formative period.
