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? No clear evidence that child age or caregiver education moderated effects on expressive or receptive language, and no evidence that country income level moderated effects on receptive language. → Dowdall 2020

Evidence

Dowdall 2020

Dowdall, N., Melendez-Torres, G. J., Murray, L., Gardiner, F., Harrtford, L. & Cooper, P.J. (2020). Shared picture book reading interventions for child language development: a systematic review and meta-analysis. Child Development, 91(2). https://doi.org/10.1111/cdev.13225

q3 · i? · quant-synthesis · r3

Pre-specified subgroup meta-regression analyses across the included RCTs, with age dichotomized at 36 months, education dichotomized at majority tertiary, and HIC vs LMIC. All three moderator tests were non-significant; continuous-age analyses were similarly non-significant.

"There was no clear evidence that child age or caregiver education moderated the effect of the intervention on either expressive or receptive language outcomes, and there was no evidence that country income level moderated the effect of the intervention on receptive language."
