Subclaims¶

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q3 i? Bullied children scored lower on 7 of 10 NIH Toolbox Cognitive domains than non-bullied children. → Menken 2022

q3 · i? · associational · r2

Cross-sectional ABCD analysis using the NIH Toolbox Cognition Battery. The study reports "Children in the bullied group had lower scores on 7 of 10 NIH Toolbox Cognitive domains" with cognition total differences of 1.1 for boys and 1.7 for girls, both p < 0.001.

"Children in the bullied group had lower scores on 7 of 10 NIH Toolbox Cognitive domains than children who were in the non-bullied group (Figure 4A; cognition total difference for boys = 1.1, p < 0.001; girls = 1.7, p < 0.001"

Discussion¶

Learner Variables¶

Safety — predictor: learners who differ on it differ in outcomes

Bullied girls show lower episodic memory and crystallized composite cognitive scores than non-bullied girls — a narrower finding that bears on this claim
Bullied preadolescents score lower than matched non-bullied peers on reading, processing speed, and inhibitory control/attention over two years — a narrower finding that bears on this claim
Sex moderates bullying-related cognitive and brain differences, with effects in boys and girls appearing in different regions and tasks — related
Bullied preadolescent children have poorer academic grades than non-bullied peers — related
Larger right fusiform surface area in bullied children partially suppresses the negative effect of bullying on crystallized composite and vocabulary scores — related
Bullied preadolescent children show greater behavioral problems across CBCL domains than non-bullied peers — related
Caregiver-reported bullying victimization is associated with higher odds of NSSI/passive suicidality and active suicidality in preadolescent children — related
Bullied children with NSSI or suicidality show greater behavioral problems and poorer grades than bullied children without these behaviors — related
