Development and validation of the lifetime sense of safety scale in Kenyan adults.
Article in Communications 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
backgroundSafety supports psychological wellbeing and potentially shapes brain aging yet existing scales overlook cumulative lifespan safety experiences.
methodsTo address this gap, we developed and validated the Lifetime Sense of Safety (LSS) scale in Kenyan adults. The LSS uses visual analog scaling with a red-to-green color gradient to retrospectively rate felt safety across life stages and settings. We evaluated scale psychometrics and associations with social determinants of health and indicators of brain health.
resultsThe LSS shows adequate internal consistency and test-retest reliability, with two distinct but correlated factors representing childhood and adulthood safety. Women and individuals experiencing poverty report lower lifetime safety. Total LSS scores correlate negatively with stress and anxiety and positively with resilience and memory.
conclusionsThe LSS is a psychometrically valid tool for evaluating cumulative lifespan safety in Kenyan adults. Longitudinal studies combining the LSS with neuroendocrine, inflammatory, and neuroimaging measures could identify mechanisms linking safety to brain health.
