Background: Adolescence is a developmental phase characterised by profound biological, emotional and social changes and these changes make adolescents particularly vulnerable to the emergence of psychiatric disorders. In this context, gender differences in mental health disorders are of increasing clinical interest. Method: We conducted a scoping review of the literature regarding gender differences in psychiatric disorders during adolescence. Three databases, PubMed, Web of Science and EBSCO, were used to identify articles published in English from 2015 until 2025. Twenty-one studies fulfilled the inclusion criteria. Results: Ten studies deal with mood disorders, with a focus on gender differences in depression and anxiety during adolescence. Two articles analyse eating disorders, highlighting that girls show higher levels of food restriction and body dissatisfaction. Two studies focus on externalising and neurobehavioural disorders, showing a higher prevalence in boys than in girls. Four articles examine self-harm and suicidal behaviour, where girls report higher rates of suicidal ideation and self-harm. Finally, two studies address personality disorders in adolescence, noting a higher incidence of borderline traits and impulsive behaviour among girls. Conclusions: Research has revealed gender differences in the onset, frequency and factors associated with psychiatric disorders in adolescence. Understanding these differences is essential for developing prevention strategies, early diagnosis and specific interventions.
