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? Family-risk (FR) and language-impaired (LI) status were each significantly associated with elevated risk indices, with no FR × LI interaction. → Dilnot 2017

q3 · i? · associational · r2
Univariate and multivariate ANOVA on risk indices in a longitudinal sample of 251 preschool children (FR, LI, FR+LI, control groups). The study reports "a significant effect of FR (F(4,157) = 2.53, p<.05)" and of LI status on risk indices, with no FR × LI interaction.
"A multivariate analysis of variance found that there was a significant effect of FR (F(4,157) = 2.53, p<.05) and of LI status ((F(4,157) = 8.64, p<.001) on risk indices and the interaction between FR and LI was not significant (F(4,157) <1)."
Discussion¶
Related Claims¶
- Family-risk of dyslexia and preschool language impairment are additive risk factors for reading readiness and attention and behaviour — related
- Family-risk of dyslexia does not predict readiness to learn once other distal, proximal and child risk factors are controlled — related
- Home literacy environment and child health predict reading readiness at school entry, and socioeconomic status stops being a significant predictor once home literacy environment is entered (suggestive of mediation, not tested) — related
- Children at family-risk of dyslexia perform more poorly than typically developing controls on the cognitive foundations of arithmetic and on arithmetic itself — related
- Home literacy environment and family stresses predict attention and behaviour at school entry — related
