Testing autonomous motivation as a mechanism of anticipated regret intervention techniques for seasonal flu vaccination.
Trial report in Annals of behavioral medicine : a publication of the Society of Behavioral Medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundAnticipated regret is associated with vaccination. However, gaps in understanding mechanisms of anticipated regret and how to intervene using anticipated regret limit its use as an intervention to promote vaccination. PURPOSE: Address gaps in anticipated regret interventions to promote seasonal flu vaccination. In a randomized intervention, we tested the novel hypothesis that autonomous motivation is a target mechanism of anticipated regret and the effects of 2 techniques to elicit anticipated regret: self-generated and mere measurement.
methodsCollege students (N = 263) were randomized to complete (1) an open-ended anticipated regret prompt (self-generated), (2) anticipated regret questions (mere measurement), or (3) no anticipated regret questions or prompts. Participants then completed measures of motivation and vaccination intentions. The following spring, participants reported their vaccination status. Analyses were guided by the experimental medicine approach.
resultsSelf-generated anticipated regret led to greater autonomous motivation for vaccination (d = 0.39), evidence of target mechanism engagement. Self-generated anticipated regret also had a significant indirect effect on intentions (estimate = 0.335, 95% CI = 0.117-0.55) and vaccination (estimate = 0.035, 95% CI = 0.008-0.08) through autonomous motivation, evidence of target mechanism validation. However, neither anticipated regret intervention technique had a direct effect on intentions or vaccination.
conclusionsAutonomous motivation is a viable target mechanism of anticipated regret interventions to promote seasonal flu vaccination, and self-generated anticipated regret is an effective technique to engage autonomous motivation. Findings provide ample evidence for testing autonomous motivation as a mechanism of anticipated regret interventions in other contexts.
