Health literacy and digital health service use among community residents in Taiwan: implications from a pilot assessment using the HLS-SF12.
Article in BMC public health, 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
backgroundHealth literacy influences individuals’ ability to prevent illness, manage chronic conditions, and effectively use digital health tools. Validated measurement tools and evidence remain limited for aging Asian populations. This study assessed the psychometric properties of the 12-item Short-Form Health Literacy Scale (HLS-SF12) and examined sociodemographic and behavioral factors associated with health literacy among community residents in Taiwan.
methodsThis cross-sectional study included 365 adults recruited from community health centers across Taiwan between September 25, 2024, and May 27, 2025. Participants completed the 12-item Short-Form Health Literacy Scale (HLS-SF12) and provided sociodemographic and behavioral information. Internal consistency and construct validity were assessed using Cronbach’s α, the Kaiser–Meyer–Olkin (KMO) index, and Bartlett’s test of sphericity. Group differences were analyzed with t-tests and χ² tests, and logistic regression was performed to examine factors independently associated with low health literacy in this cross-sectional sample. Ethical approval was obtained from the Institutional Review Board of Tainan Municipal Hospital (IRB No. 1140403).
resultsThe HLS-SF12 demonstrated excellent internal consistency (Cronbach’s α = 0.920). KMO (0.928) and Bartlett’s test (p < 0.001) indicated that the data were suitable for exploratory factor analysis, which was exploratory and sample-specific. Hypertension was the most common chronic condition, and the prevalence of multimorbidity was significantly higher among participants living in southern regions (p = 0.014). Lower scores were observed in areas such as evaluating treatment options, understanding vaccination requirements, and accessing mental health information. Lack of regular medical visits was associated with higher odds of low health literacy in this cross-sectional analysis (adjusted OR = 4.5; 95% CI, 1.2–16.1), without implying causality.
conclusionsThe HLS-SF12 appears to be a reliable and valid tool for assessing health literacy in community-based research. Findings highlight gaps in digital and mental health literacy among Taiwanese adults and underscore the need for region-specific, digitally inclusive interventions. These results may also inform research and interventions in other aging, technology-dependent health systems.
