Academic Stress and Depressive Symptoms in High School Students: A Random Intercept Cross‐Lagged Panel Model and Cross‐Lagged Panel Network Analysis

ABSTRACT

Despite evidence linking academic stress and depressive symptoms, cross‐sectional designs cannot reveal their developmental dynamics, and total‐scale scores obscure symptom‐level complexity and intervention targets. We applied the random intercept cross‐lagged panel model (RI‐CLPM) and cross‐lagged panel network (CLPN) analysis to 307 Chinese adolescents (58.63% female) to examine the relationship between academic stress and depressive symptoms from the aggregate to the symptom level and to identify key nodes. Results from the RI‐CLPM indicated a positive association between academic stress and depressive symptoms at the between‐person level. At the within‐person level, Time‐1 academic stress predicted a reduction in Time‐2 depressive symptoms. CLPN results revealed complex reciprocal influences: ‘People were unfriendly’ and ‘I felt hopeless about the future’ were initially vulnerable and later progressed to ‘I felt sad’ and ‘I thought my life had been a failure’. Early drivers included ‘I thought my life had been a failure’ and ‘I felt that people dislike me’, whereas over time ‘I was unhappy’ and ‘I felt hopeless about the future’ gained predictive importance. The study revealed temporal relationships between academic stress and depressive symptoms and identified potential targets, providing evidence and implications for prevention and intervention.
