Adherence
Nudging interventions that combine altering both the properties and the placement of fruit and vegetables yield a significant, medium effect size on increasing selection.
For maximum impact, combine strategic placement (e.g., eye-level, front-of-counter) with property alterations (e.g., attractive presentation, priming, or sizing cues). This dual approach significantly boosts fruit and vegetable selection compared to control conditions.
GoodSupportsMEDIUM confidence
The overall effect of nudging by altering properties and placement of a product is significant, with a medium effect size (P = 0.02; effect size d = 0.28 [95% CI = 0.050–0.499]).
Why this rating
Based on a subgroup of 5 studies within the meta-analysis, showing consistent significant effects in 3 of them.
