Loneliness in adolescence: prevalence, developmental contexts, and interventions

Area of Science:

• Psychology
• Adolescent Development
• Public Health

Background:

• Loneliness is a distinct subjective experience, not merely social isolation, impacting all life stages.
• Adolescence is a critical developmental period marked by identity, cognitive, and social changes, increasing vulnerability to loneliness.
• Global research indicates widespread adolescent loneliness, influenced by cultural and societal factors.

Purpose of the Study:

• To examine the prevalence and contributing factors of adolescent loneliness.
• To explore the mental and physical health implications of adolescent loneliness.
• To review and propose effective intervention strategies for adolescent loneliness.

Main Methods:

• Global research synthesis on adolescent loneliness.
• Analysis of developmental transitions and social environmental factors.
• Examination of intervention strategies targeting skills, relationships, and cognitions.

Main Results:

• Adolescent loneliness is widespread and associated with depression, anxiety, social anhedonia, and health risks.
• Persistent loneliness can lead to maladaptive withdrawal and self-sustaining cycles of disconnection.
• Interventions should enhance social-emotional skills, strengthen relationships, and address maladaptive cognitions.

Conclusions:

• Adolescence is a sensitive period for loneliness, necessitating timely, evidence-based interventions.
• Effective interventions require differentiation between transient and chronic loneliness and cultural sensitivity.
• Co-production with young people is crucial for developing relevant and effective loneliness interventions.
