Reinforcing implementation intentions with imagery increases physical activity habit strength and behaviour.
Trial report in British journal of health psychology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectivesHabits may enhance the maintenance of physical activity. The aim of this study is to examine if reinforcing implementation intentions increases habit strength and thus physical activity.
designParticipants (N = 186) were randomized into one of three intervention conditions (imagery vs. implementation intentions vs. combined; implementation intentions and imagery) and a control condition.
methodsParticipants were instructed to engage in a physical activity that they would like to start doing, or do more of, over a four-week period. Participants completed measures of physical activity, habit strength, and imagery use (imagery and combined conditions only) pre-intervention, weekly during the intervention, post-intervention, and a 12-week follow-up.
resultsHabit strength increased at week three (p < .001) for those in the combined condition, which was maintained through post-intervention and increased at follow-up (Ps > .05). In the imagery condition, habit strength increased at post-intervention (p = .003) and was maintained at follow-up. Physical activity increased for the combined condition from week two (p < .001) of the intervention, continuing to increase at weeks three (p = .003) and four (p < .001).
conclusionsImagery may be an effective intervention to support habit formation. Reinforcing implementation intentions with mental imagery may support habit formation for physical activity behaviour.
