q2 i? In the one formal mediation analysis reported, improvements in caregiver sensitivity mediated the intervention's effect on receptive language, and improvements in caregiver-child reciprocity mediated effects on expressive language, receptive language and focal attention. → 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

q2 · i? · quant-synthesis · r3

The review reports, citing Murray et al. (2016), the only formal mediation analysis among included studies: caregiver sensitivity mediated the receptive-language effect and caregiver-child reciprocity mediated expressive and receptive language effects.

"Murray and colleagues (2016) found that improvements in caregiver sensitivity during book-sharing significantly mediated the impact of the intervention on receptive language, while improvements in caregiver-child reciprocity during book-sharing mediated the impact of the intervention on both child expressive language and receptive language (and child focal attention)."

Related Claims¶

• Book-sharing interventions produce a large improvement in caregiver book-sharing competence (d=1.01) — related
• Child age, caregiver education and country income level do not moderate book-sharing intervention effects on child language — related
• Group-based delivery is associated with more improvement in child language than individually delivered interventions — related
• Caregiver-directed shared book-reading interventions have a small positive effect on child receptive language (d=0.26) — related
• Interventions that change educator behaviour to match standard global definitions of quality have delivered negligible effects on children's developmental outcomes — reports the opposite
• 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
