Development and Psychometric Evaluation of the Critical Reflection Competency in Delirium Care Scale (CRCDCS) Among Iranian ICU Nurses.
Article in Nursing open, 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
aimThis study aimed to develop and psychometrically evaluate the Critical Reflection Competency in Delirium Care Scale (CRCDCS) among ICU nurses in Iran.
designThis exploratory mixed-methods study was conducted in Iran between June 2025 and March 2026 based on the eight-step scale development framework proposed by DeVellis and Thorpe.
methodsItem generation was performed using a systematic literature review and semi-structured interviews with 15 ICU nurses. Following qualitative and quantitative assessment of content and face validity, the preliminary 19-item CRCDCS was administered to 700 ICU nurses. Participants were randomly allocated into two equal subsamples for exploratory factor analysis (EFA; n = 350) and confirmatory factor analysis (CFA; n = 350). Psychometric evaluation included parallel analysis (PA), exploratory graph analysis (EGA), convergent and discriminant validity, random forest modeling (RFM), and reliability assessment using Cronbach's alpha (α), McDonald's omega (ω), intraclass correlation coefficient (ICC), and standard error of measurement (SEM).
resultsEFA identified a three-factor structure comprising Analytical-Evaluative Clinical Reflection (AECR), Person-Centered Ethical Reflection (PCER), and Risk-Oriented Preventive Reflection (ROPR), explaining 57.34% of the total variance. PA, EGA, and CFA supported the three-factor model with excellent fit indices (χ
conclusionThe CRCDCS demonstrated sound internal structure, internal consistency, and test-retest reliability among ICU nurses in this Iranian sample. Further research is needed to establish external criterion validity, predictive validity, and measurement invariance before broader application of the scale. IMPACT: The CRCDCS is a multidimensional instrument for assessing ICU nurses' critical reflective competence in delirium care, capturing analytical, ethical, and preventive dimensions of reflective practice. Pending further validation, the scale may inform the design of educational programs and clinical training aimed at strengthening reflective decision-making in delirium care within critical care settings.
