Randomized trial analyzes symptom networks in different age groups, indicating notable variations in dynamics across ages.

The study aims to explore the causal relationships of depressive symptoms across various age groups using panel network analysis.
Utilized four-wave longitudinal data from the China Family Panel Studies (N=12,013).
Applied panel network approach to differentiate between-person and within-person processes.
Estimated networks for adolescents, young adults, middle-aged adults, and older adults.
In adolescents, 'I felt lonely' emerged as the most predictive symptom.
Young adults and middle-aged adults showed density in network connectivity, with 'I felt depressed' and 'I felt life could not go on' as key symptoms, respectively.
Older adults displayed lower network connectivity, yet 'I felt depressed' remained central.
