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? The poor academic performance group had a larger proportion of children with DIMS and more internalizing and externalizing problems than the average-to-good group (all comparisons p < .001). → Stormark KM 2019
Evidence¶
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
Bivariate comparisons (chi-square and Kruskal-Wallis tests) between the poor academic performance group (10.5% of the cohort) and the average-to-good group, reported in Table 1. All listed contrasts reached "p< .001".
"The low academic performance group comprised a significant larger proportion of children with DIMS, larger proportion of children with delayed pubertal development, less affluent family economy, lower levels of parental education and more mental health problems than the control group (all comparisons p< .001)."
Discussion¶
Related Claims¶
- Sleep education at school improves academic performance in children — 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 — related
- The association between sleep problems and poor school performance is partly mediated by children's internalizing and externalizing mental health problems, with a direct effect remaining only for persistent DIMS — related
- Concurrent sleep problems at age 11–13 do not increase the risk of poor academic performance after controlling for mental health problems — related
