Psychometric Properties of the Persian Version of the Delirium Care Self-Efficacy Scale for Intensive Care Unit Nurses: A Methodological Study.
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
AIM(S): Currently, no valid and reliable instrument exists in Persian to assess intensive care unit (ICU) nurses' self-efficacy in delirium care, which limits the ability to identify educational needs and evaluate targeted interventions in Iranian critical care settings. This study aimed to evaluate the psychometric properties of the Persian version of the Delirium Care Self-Efficacy Scale (P-DCSE-I) for ICU nurses in Iran.
designA methodological study with a cross-sectional design.
methodsThe original scale was translated into Persian using a forward-backward method. Psychometric properties were assessed among 209 ICU nurses in Ardabil, Iran. Face and content validity were evaluated qualitatively and quantitatively. Construct validity was examined through Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA). Reliability was assessed using internal consistency and test-retest reliability.
resultsQualitative face and content validity were confirmed following minor revisions. The Kaiser-Meyer-Olkin (KMO) measure was 0.921, and Bartlett's Test of Sphericity was significant (χ
conclusionThe P-DCSE-I demonstrates strong validity and reliability. It is a suitable instrument for measuring delirium care self-efficacy among ICU nurses in Iran and is useful for clinical assessment and research. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: This valid and reliable instrument enables the assessment of ICU nurses' confidence in delirium care, facilitating the identification of educational needs and the evaluation of targeted training interventions to improve patient safety and quality of care for critically ill patients with delirium. IMPACT: Currently, no valid and reliable instrument exists in Persian to assess ICU nurses' self-efficacy in delirium care, limiting the ability to identify educational needs and evaluate interventions in Iranian critical care settings. The Persian version of the DCSE-I demonstrated strong psychometric properties, including a two-factor structure, acceptable internal consistency, and acceptable test-retest reliability. This instrument will support ICU nurses, nurse educators, and researchers in Iran and other Persian-speaking populations by facilitating evidence-based assessment and improvement of delirium care practices. REPORTING
methodThis study adhered to the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) checklist guidelines for study design and reporting. PATIENT OR PUBLIC CONTRIBUTION: A total of 209 ICU nurses participated in this study. No patients, service users, caregivers, or members of the public were involved in the design, conduct, analysis, interpretation, or preparation of this manuscript.
