Abstract:
Objective:To explore the development and interaction between chronotype and depressive symp-toms among middle school students in Chongqing.Methods:A total of 1208 middle school students(613 in grade 7,595 in grade 10)were surveyed for three follow-ups at 6-month intervals.Periods T1-T3 represented baseline,6 months later,and 12 months later,respectively.Chronotype and depressive symptoms were measured by the Morn-ing and Evening Questionnaire-5(MEQ-5)and the Patient Health Questionnaire-9(PHQ-9).Analyses were per-formed using SPSS 26.0 and Mplus 8.3.Results:The MEQ-5 scores were lower in T1 than in T3,and the scores were lower in T2 than in T1 and T3(F=20.08,P＜0.001),suggesting a fluctuating trend of chronotype shifting to the Evening-type first after baseline and then to the Morning-type.The PHQ-9 scores exhibited a significant differ-ence among the three-time measurements(x2/df=9.77/2,P＜0.01).But pairwise comparisons did not yield any statistically significant findings(P＞0.05).The cross-lagged panel model showed that pathways of Ti MEQ-5 scores negatively predicted Ti+1 PHQ-9 scores(βTi-Ti+1=-0.12/-0.09,P＜0.05)and TiPHQ-9 scores nega-tively predicted Ti+1 MEQ-5 scores(βTi-Ti+1=-0.07/-0.11,P＜0.05).Conclusion:Chronotype and depressive symptoms show some changes in adolescents.The more inclined adolescents are to the Evening-type,the higher the likelihood of depressive symptoms occurring later.The more severe the depressive symptoms,the greater the likeli-hood of a subsequent shift to the Evening-type.
