Outline
To explore the predictive relationships among depressive symptoms over time and identify core symptoms within the depressive symptom network in empty-nest older adults in China.
Data were obtained from 1 462 eligible empty-nest older adults in the 2018 and 2020 waves of the China Health and Retirement Longitudinal Study（CHARLS）. Depressive symptoms were measured using the Center for Epidemiologic Studies Depression Scale（CESD-10）. A cross-lagged panel network（CLPN）model was fitted and analyzed using R version 4.3.3.
Feeling afraid, loneliness, and effortful behavior were the symptoms with the strongest outgoing predictive effects, significantly predicting changes in other symptoms at the next time point. Additionally, gender differences were observed: depressive symptoms in men were more likely to originate from loneliness, whereas in women, they were more associated with fear.
Intervention strategies should consider gender differences and focus on core symptoms to prevent the progression to high-risk depression among empty-nest older adults with depressive tendencies.
