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? Mediation through internalizing and externalizing problems was significant for all DIMS groups, but a significant relative direct effect on poor school performance remained only in the Persistent DIMS group (log odds ratio 0.7076, p < .001). → Stormark KM 2019

Stormark KM, Fosse HE, Pallesen S, Hysing M (2019) The association between sleep problems and academic performance in primary school-aged children: Findings from a Norwegian longitudinal population-based study. PLoS ONE 14(11): e0224139. https://doi.org/10.1371/journal.pone.0224139
q3 · i? · associational · r2
Parallel multiple mediation analysis (PROCESS macro, 5,000 bootstrap samples) with internalizing and externalizing SDQ subscales as mediators. The "significant relative direct effect in Persistent DIMS group (log odds ratio of 0.7076, p< .001)" was absent in the Concurrent group.
"there was still an overall significant direct relative effect of DIMS on poor school performance (χ(3) = 14,26 p< .001), due to a significant relative direct effect in Persistent DIMS group (log odds ratio of 0.7076, p< .001), while not in the Concurrent DIMS group (log odds ratio of 0.2240, p = .23)"
Discussion¶
Related Claims¶
- Sleep education at school improves academic performance in children — related
- Children with poor academic performance show more sleep problems, delayed pubertal development, poorer family economy, lower parental education and more mental health problems than average-to-good performers — related
- Persistent sleep problems (DIMS at both ages 7–9 and 11–13) increase the risk of poor academic performance even after adjusting for mental health, gender, pubertal status and SES — a narrower finding that bears on this claim
- Concurrent sleep problems at age 11–13 do not increase the risk of poor academic performance after controlling for mental health problems — related
- Transitory sleep problems (DIMS at age 7–9 only) do not increase the risk of later poor academic performance — related
