Psychometric evaluation of the Persian version of the adult chronic kidney disease self-management instrument in the Iranian population.
Article in BMC nephrology, 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
backgroundIncreasing evidence suggests that self-management practices can enhance the results for individuals with chronic kidney disease (CKD). Nevertheless, there are currently no tools in Iran to adequately evaluate self-management in CKD patients. This study aimed to validate and psychometrically evaluate the Persian Chronic Kidney Disease Self-Management for Iranian healthcare professionals and patients.
methodsIn this cross-sectional study, after the scale translation, the adaptation and validation were assessed in a sample of 400 patients with CKD who were receiving treatment at nephrology wards and clinic centers affiliated with Ahvaz Jundishapur University of Medical Sciences in Iran. Face and content validity were evaluated using both quantitative and qualitative methods. Construct validity was established through exploratory and confirmatory factor analysis. The reliability of the instrument was assessed through measures of internal consistency, as well as relative and absolute reliability.
resultsFollowing the completion of construct validity and factor analysis, a 15-item instrument with three key factors was identified: self-efficacy, ability to acquire knowledge and problem-solve, and knowledge. These factors accounted for a total variance of 44.18%. The results of the confirmatory factor analysis indicated a strong fit for the model. Each factor demonstrated acceptable internal reliability, with Cronbach's α values ranging from 0.73 to 0.83. Furthermore, the scales exhibited strong stability, as evidenced by an overall Intraclass Correlation Coefficient result of 0.961. The absolute reliability, as determined by Standard Error of Measurement results, was 3.16. Additionally, the Minimum Detectable Change was estimated to be 8.75.
conclusionsThe findings of this study demonstrate that the CKD-SM Instrument is both valid and reliable for use in tailoring interventions for Iranian patients with CKD. Additionally, the concept being studied has three subconcepts that show sufficient reliability and applicability within the Iranian population.
