Older Adults' Continued Use of Smart Healthcare Applications: An Integrated HBM-UTAUT Model with Technology Anxiety.
Article in Healthcare (Basel, Switzerland), 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
BACKGROUND/
objectivesThis study examines the continued use of smart healthcare applications among older adults by integrating the Health Belief Model (HBM) with the Unified Theory of Acceptance and Use of Technology (UTAUT). Perceived health threat and health management self-efficacy were considered health-related antecedents, while technology anxiety was examined as a moderator.
methodsData were collected from 224 South Korean adults aged 60 years or older with prior experience using smart healthcare applications. Confirmatory factor analysis and structural equation modeling were used to assess the measurement and structural models. Indirect effects were tested using 5000 bootstrap resamples, and moderation was examined through hierarchical regression and simple slope analysis.
resultsPerceived health threat was positively associated with performance expectancy but not with effort expectancy. Health management self-efficacy was positively associated with both performance and effort expectancy. Performance expectancy, effort expectancy, social influence, and facilitating conditions were all positively associated with behavioral intention, which showed the strongest relationship with actual use behavior. Technology anxiety significantly weakened the relationship between social influence and behavioral intention, whereas its moderating effects on performance expectancy and effort expectancy were not significant.
conclusionsThe findings provide an integrated explanation of continued smart healthcare application use among older adults by linking health-related beliefs, UTAUT factors, and technology anxiety. Sustained use may be promoted by strengthening self-efficacy, improving usability, and reducing technology-related anxiety through accessible design and appropriate support.
