Joint trajectories of bullying and peer victimization across elementary and middle school and associations with symptoms of psychopathology.
Bibliographic record
Abstract
The joint development of trajectories of bullying perpetration and peer victimization from Grade 5 to Grade 8 and concurrent and predictive associations with parent- and child-reported symptoms of psychopathology (anxiety, depression, attention-deficit/hyperactivity disorder, and somatization) were examined in a large sample (N = 695) of Canadian children. Dual trajectory modeling revealed four distinct subgroups of children: (a) those low in both bullying perpetration and peer victimization (low/limited involvement); (b) those with moderately increasing levels of involvement in bullying perpetration and low levels of victimization (bullies); (c) those with low levels of bullying perpetration and moderate/decreasing levels of peer victimization (initial/declining victims); and (d) a victim-to-bully group characterized by increasing bullying perpetration and moderate decreasing victimization. Conditional probability results suggest that a pathway from peer victimization to involvement in bullying is more likely than a pathway from bullying perpetration to peer victimization. Children classified in the victim-to-bully and initial/declining victim groups showed more pervasive elevations in parent- and child-reported symptoms of psychopathology across elementary and middle school and in Grade 9 than individuals with limited involvement in bullying or peer victimization. Most associations with Grade 9 parent- and child-reported symptoms of psychopathology remained even after controlling for initial symptoms of psychopathology. Results are discussed in the context of extant taxonomies of involvement in bullying, the temporal relationship between bullying and victimization, and the increased mental health risk associated with both pure victims and bully-victims.

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.
