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? Using mathematics performance below 1 SD below the mean with reading above 1 SD below the mean, 99 children (5.6%) met DD criteria, with similar numbers of girls and boys. → Devine 2017

q3 · i? · associational · r3
In the 1757-child sample, DD was defined as mathematics performance below 1 SD below the mean with reading performance above 1 SD below the mean; "99 children (5.6%) were included in the group of children with DD". Chi-square showed no significant gender difference (χ2 = 1.82, p =.18; φ = .032).
"Using the absolute threshold definition of DD used by Devine et al (2013), 99 children (5.6%) were included in the group of children with DD."
Discussion¶
Related Claims¶
- Developmental writing disorders affect about 7–15% of school-aged children, with boys more affected than girls — related
- Children with developmental dyscalculia are twice as likely to have high mathematics anxiety as children with typical mathematics performance
- Definitions of developmental dyscalculia vary widely across studies, with diagnostic cutoffs ranging from below the 3rd to below the 25th percentile — related
- The majority (77%) of children with high mathematics anxiety have average or above-average mathematics performance — related
- Sample selection criteria moderate MLD effect sizes: stricter cutoffs, specificity, and age change group differences — related
