Rooted in routine: Fostering higher order vegetable-shopping habits using a randomised simple planning intervention.
Trial report in Applied psychology. Health and well-being, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
A healthy diet is a protective factor against a host of negative health outcomes. To maintain such a diet necessitates the consumption of at least 240 g of vegetables per day. However, most of the population fails to meet this threshold. Utilising a randomised controlled trial, the present study tested the effectiveness of a one-off higher order habit intervention aimed at shopping for a variety of vegetables and the mechanisms that may support such habit development. Specifically, participants (N = 198; 54.5% female; 20 to 74 years of age) were allocated to the intervention or control group to explore (1) how effective an action- and coping-planning intervention is at targeting the formation of vegetable-shopping higher order habits and (2) whether healthy-eater identity, intrinsic motivation and self-efficacy were mechanisms of action. Follow-up measures of habit, the mechanisms of action and behaviour were taken post-intervention, weekly for 4 weeks and at 3- and 6-month follow-ups. The intervention led to stronger higher order habit formation after 6 months and that it was particularly effective for those with low baseline higher order habits for vegetable shopping. These findings demonstrate that a simple, one-off, intervention can lead to long-lasting change in higher order habits within the nutrition domain.
