Existing SNHV trials show relatively modest effects (effect
sizes of 0.2 — 0.4 SDs)
for outcomes such as child mental health and behaviour, and
cognitive and language
development, from infancy to mid - childhood.19 While effect
sizes of 0.25 — 0.3 SDs can be meaningful and impactful at the whole of population level, 59 targeted public health interventions such as SNHV include a cost and intensity such that larger effects in the short - to - medium term might be necessary to justify implementation at a population level.
The meta - analyses showed the most pronounced effect
sizes for parent — child interaction and maternal sensitivity, whereas the effects on child behaviour and
cognitive development were either small or not significant; however, small effect
sizes can have meaningful impact on population - level outcomes.60 The non-significant outcomes
for internalising and externalising behaviours were also small, but may be clinically relevant
for large, at - risk populations.
