q3 i? Compared to individually delivered interventions, group-based interventions were associated with more improvement in expressive (B=0.47, p<0.01) and receptive (B=0.30, p=0.02) 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

Subgroup meta-regression restricted to face-to-face interventions (video- and phone-only studies excluded). Group-based delivery outperformed individual delivery on both language outcomes, though degrees of freedom were below the advised level.

"For modality, there was evidence (p<0.01) that, compared to individually delivered interventions, group-based interventions were associated with more improvement in both expressive language (B=0.47; CI: 0.17, 0.77; p<0.01) and receptive language (B=0.30; CI: 0.06, 0.54; p=0.02)."
