DINA HALO SAFETY: A Peer-Led Digital Intervention for Road Safety Behaviour and Psychosocial Outcomes Among Indonesian Undergraduate Students.
Article in International journal of behavioral medicine, 2026. 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
purposeThis study tested whether DINA HALO SAFETY, a 4-week peer-led digital road safety programme consisting of microlearning videos, moderated WhatsApp Messenger discussions, and Instagram reinforcement posts, improved self-reported safe riding behaviour and theory-based psychosocial determinants among Indonesian undergraduate motorcycle users.
methodA quasi-experimental study with non-equivalent intervention and control groups (n = 80) collected data at baseline, week 2, and week 4. Higher scores indicated safer behaviour and more favourable psychosocial determinants. Outcomes included road safety behaviour, knowledge, attitudes, behavioural intention, self-efficacy, risk perception, and peer influence. Analyses used paired and independent t-tests and repeated-measures analysis of variance (ANOVA) to examine time, group, and time × group effects.
resultsThe intervention group showed larger improvements than the control group in road safety behaviour, knowledge, attitudes, and intentions, with significant time × group effects. Risk perception improved over time, whereas self-efficacy and peer influence did not show significant interaction effects.
conclusionDINA HALO SAFETY was associated with short-term improvements in self-reported safe riding behaviour and several theory of planned behaviour (TPB)-aligned determinants, although stronger experiential and social-norm components may be needed to change self-efficacy and peer influence.
