This study aims to explore the effectiveness of digital interventions combined with medication in the treatment of patients with depressive disorders. Its main aim is to answer: Can digital interventions combined with medication effectively alleviate symptoms of depression? The experiment will compare the effects of medication combined with digital interventions to those combined with online mental health education to evaluate their relative effectiveness.
