A Cross-National Examination of Adverse Childhood Experiences and Depression in Young Adults: The Mediating Roles of Emotion Regulation, Distress Tolerance, and Rumination
Bibliographic record
Abstract
Adverse childhood experiences have been linked to poor mental health outcomes, including depression, yet the underlying mechanisms remain unclear. The present study aimed to investigate how adverse childhood experiences are related to depressive symptoms among college students, focusing on emotion regulation, distress tolerance, and rumination as potential mediating pathways. Our analytic sample consisted of 4,337 participants (67.2% female) from six countries—United States, Canada, Spain, England, Argentina, and South Africa—who completed questionnaires assessing their adverse childhood experiences, depressive symptoms, use of emotion regulation strategies, distress tolerance, and ruminative thinking. We used a comprehensive mediation model in Mplus 8.3 (Muthén & Muthén, 1998–2017) to test for significant pathways. Within our model, greater adverse childhood experiences were significantly associated with greater depressive symptoms through several mediators: greater use of expressive suppression (an emotion regulation strategy), lower distress tolerance, and increased ruminative thinking across three facets (problem-focused, repetitive, and anticipatory thoughts). Model invariance analyses suggested that these findings were consistent across countries and sex at birth. The results highlight the importance of targeting emotion regulation, distress tolerance, and rumination in interventions aimed at reducing depression, particularly among individuals with a history of childhood adversity. Furthermore, the findings suggest that interventions targeting these mechanisms may be broadly applicable across global populations. Future research should employ longitudinal designs to further clarify the directionality of these associations and examine them across more diverse populations, including various age groups and cultural backgrounds. Keywords: adverse childhood experiences, depression, emotion regulation, distress tolerance, rumination

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
