The role of hopelessness and gratitude in the association between brooding and Chinese college students’ suicidal ideation: a moderated mediation model
Bibliographic record
Abstract
Based on the cognitive model of suicide and broaden-and-build theory of gratitude, this study constructed a moderated mediation model to examine whether hopelessness mediated the relationship between brooding and Chinese college students' suicidal ideation and whether this mediating process was moderated by gratitude, from the positive psychology perspective. A total of 1191 college students were investigated using four scales. The results were as follows: (1) Brooding significantly contributed to suicidal ideation; (2) Hopelessness played a mediating role in the relationship between brooding and suicidal ideation; and (3) Gratitude moderated the mediated path through hopelessness, such that this mediating effect was only significant in individuals with low gratitude. This study may shed light on how brooding influences Chinese college students' suicidal ideation theoretically and on their prevention practically.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
