Psychometric evaluation of a Korean-language version of the Nursing Home Survey on Patient Safety Culture (K-NHSPSC).
Article in BMC nursing, 2025. 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
backgroundPatient safety culture is a foundational component of quality care in long-term care facilities. Although the Nursing Home Survey on Patient Safety Culture (NHSPSC) has been widely used and validated internationally, there has been no validated Korean version applicable to the Korean context. This study aimed to translate, culturally adapt, and validate the NHSPSC for use in Korean long-term care settings.
methodsWe employed a two-phase design. In Phase 1, the original NHSPSC was translated into Korean using a committee-based translation method, followed by an expert review for content validity. A panel of five experts rated the relevance and clarity of each item. Subsequently, cognitive interviews were conducted with five nursing home staff to assess item comprehension and cultural appropriateness. In Phase 2, a cross-sectional survey was administered to healthcare workers in 10 nursing homes. After applying exclusion criteria, data from 282 participants were analyzed. Internal consistency was assessed using Cronbach’s alpha. Construct validity was evaluated through confirmatory factor analysis and correlations with global safety ratings.
resultsThe Korean version of the NHSPSC retained all 12 original factors and demonstrated acceptable internal consistency. Confirmatory factor analysis supported the factorial structure of the instrument. Correlations between subscales and global safety ratings provided additional support for construct validity.
conclusionsThe Korean version of NHSPSC demonstrated acceptable psychometric properties and retains the original instrument’s multidimensional structure. It is a reliable and valid tool for assessing patient safety culture in Korean nursing homes and can facilitate both domestic quality improvement and international benchmarking efforts.
