Abstract
Background: Childhood trauma (CT) is considered as a highly risk factor for depression. Although the pathway of CT to depression, especially the mediating or moderating effects of cognitive emotion regulation strategies (CERS) or neuroticism, have investigated by several studies, the results were inconsistent and there is a paucity of full models among these interactive factors. This study aims to examine the relationships among CT, adaptive / maladaptive CERS, neuroticism and current depression symptoms in university students.Methods: We recruited 3009 students, aged averagely 18.00 (SD = 0.772) years, from universities in Hunan province in 2019. A moderated mediation model was built to examine the relationships among CT, CERS, neuroticism and current depression using the SPSS PROCESS 3.5 macro. We conducted bootstrapping of regression estimates with 5,000 samples and 95% confidence interval.Results:Results revealed that the significant mediating effects of adaptive CERS (β = 0.0117; 95% CI: 0.0061 to 0.0181) and maladaptive CERS (β = 0.0278; 95% CI: 0.0161 to 0.0401) between CT and depression were observed, accounting for 5.690% and 13.521% of the total effect respectively. Then, moderated mediation analyses results showed that neuroticism simultaneously moderated the direct effect of CT on current depression (β = 0.035; 95% CI: 0.001 to 0.009), and the indirect effects of CT on current depression through adaptive CERS (adaptive CERS – current depression: β = -0.034; 95% CI: -0.007 to -0.001) and maladaptive CERS (maladaptive CERS – current depression: β = 0.157; 95% CI: 0.017 to 0.025). However, the moderating effects of neuroticism in the indirect paths from CT to adaptive CERS (β = 0.037; 95% CI: 0.000 to 0.014) and maladaptive CERS (β = -0.001; 95% CI: -0.006 to 0.005) were not significant.Conclusions: This study provides powerful evidences through a large university students sample for the mediating role of adaptive / maladaptive CERS and the moderating role of neuroticism between CT and current depression. This manifests that cognitive emotion regulation may be a vital factor for people who suffered from CT and current depression. Furthermore, the influence of neuroticism in this process cannot be ignored.
