Abstract

The central symptom of depression among middle-aged and older Chinese adults is identified as 'Felt depressed' in both 2018 and 2020.

  • No significant differences in the overall structure of depressive symptom networks were found between the two years studied.
  • Significant differences in global strength and edge strength of depressive symptoms were observed between the two waves.
  • Internet use is associated with a more complex relationship to depressive symptoms in 2020 compared to 2018.
  • Targeting central symptoms and strong connections in depressive networks could be beneficial for treatment strategies.
  • Enhancing guidance on Internet use may positively impact the mental health of older adults.
