Subclaims¶

q2 i? Within the intervention group, pre-to-post changes on the Language Scale (Z = -1.68, p = 0.09) and Motor Scale (Z = -0.76, p = 0.45) were not statistically significant. → van Eeden 2017 q2 i? Between groups after the intervention, no significant effect was found on the Language Scale (U = 622, Z = 1.78, p = 0.07) or the Motor Scale (U = 595, Z = 1.14, p = 0.16). → van Eeden 2017 (2)

Evidence¶

van Eeden 2017¶

van Eeden, R. & van Vuuren, J., 2017, 'The cognitive processing potential of infants: Exploring the impact of an early childhood development programme', South African Journal of Childhood Education 7(1), a499. https://doi.org/10.4102/sajce.v7i1.499

q2 · i? · causal · r1

Wilcoxon signed-rank tests within the intervention group (N = 29) on the Language and Motor composite scales before and after the programme; numerical increases were noted but neither reached significance. No effect sizes are printed.

"However, the intervention programme did not have a statistically significant effect in the case of the Language Scale (Z = -1.68, p = 0.09) or the Motor Scale (Z = -0.76, p = 0.45)."

van Eeden 2017 (2)¶

q2 · i? · causal · r1

Mann–Whitney U comparisons of intervention (N = 29) versus control (N = 34) groups after the intervention on the Language and Motor scales; neither difference was statistically significant. Equivalence was not tested.

"No significant effect of the intervention programme was found in the case of the Language Scale (U = 622, Z = 1.78, p = 0.07) or the Motor Scale (U = 595, Z = 1.14, p = 0.16)."

Discussion¶

Related Claims¶

• Infants exposed to the Numbers in Nappies programme showed a statistically significant increase on the BSID (III) Cognitive Scale from before to after the intervention — related
• Social–emotional functioning of intervention infants rose numerically from the high to the very superior range after the programme, which the authors attribute to added parent stimulation — related
• After the intervention, the intervention group scored significantly higher than the control group on the Cognitive Scale, with no between-group differences before the intervention — related
