Psychometric evaluation of the Spanish-language version of the health information technology usability evaluation scale (Health-ITUES).
Article in International journal of medical informatics, 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
introductionRigorous development of mobile health technologies must include assessments to ensure interventions are effective and sustainable across diverse populations. Spanish-speaking individuals represent the largest linguistic minority in the United States and globally. Several general and modality-specific usability instruments exist in Spanish; however, a validated Spanish version of Health-ITUES-a health IT-specific, customizable instrument designed for broad HIT contexts-has been lacking. The purpose of this study was to evaluate the psychometric properties of the Spanish-language version of the Health Information Technology Usability Evaluation Scale (Health-ITUES).
methodsWe analyzed survey data from 125 Spanish-speaking participants (aged 18-64 years), including 18 health professionals from the Dominican Republic and 107 persons living with HIV in New York City or the Dominican Republic. Participants interacted with a mobile health technology and completed the Health-ITUES after use. Psychometric evaluation included exploratory factor analysis, internal consistency reliability, construct validity, and criterion validity assessed through correlations with the Post-Study System Usability Questionnaire (PSSUQ).
resultsExploratory factor analysis supported a three-factor structure (Impact and Perceived Usefulness, Perceived Ease of Use, and User Control) with strong model fit (RMSR = 0.04) and internal consistency (Cronbach's α = 0.79-0.96). Within-factor correlations were higher than between-factor correlations, supporting construct validity. Criterion validity was established through significant correlations with PSSUQ subscales (r = 0.44-0.86, p < 0.001).
conclusionThe Spanish Health-ITUES demonstrated strong reliability and validity in both patient and provider samples. Findings will contribute to the rigor of research by developing a linguistically and culturally relevant usability instrument to improve inclusion of Spanish-speaking populations in digital health research.
