Network characteristics of the youth’s insomnia and emotional symptoms and their gender differences

This study revealed that insomnia, anxiety, and depression symptoms among youth are closely interconnected. Core symptoms such as "excessive worry" and "sleep dissatisfaction," along with bridge symptoms like "fatigue," "nervousness," and "suicidal ideation," represent potential intervention targets, with fatigue playing a dual role in the network. Males require particular attention regarding the intervention of "anhedonia." Targeted improvement of these key symptoms may help break the cycle of comorbidity and provide precise directions for mental health interventions among young people.
