Turkish Validity and Reliability Study of the Cardiac Self-Efficacy Questionnaire.
Article in Florence Nightingale journal of nursing, 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
aimThe aim of this study was to determine the validity and reliability of the "Cardiac Self-Efficacy Questionnaire" in Turkish.
methodsThis methodological research was conducted among 400 patients who were hospitalised at the Cardiology Clinic of Giresun University Training and Research Hospital between 25 March 2023 and 15 May 2024. The data were collected using the "Patient Introductory Form", "Cardiac Self-Efficacy Questionnaire", and "Chronic Diseases Self-Efficacy Scale".
resultsThe scale demonstrated excellent content validity, with a content validity index of 1.00. Construct validity was examined using factor analytic techniques. "The Kaiser-Meyer-Olkin measure indicated adequate sampling adequacy 0.878, and Bartlett's test of sphericity was statistically significant (p < .001), confirming the appropriateness of the correlation matrix for factor analysis." Exploratory factor analysis supported a two-factor solution control of symptoms and maintenance of functionality which collectively explained 53.55% of the total variance. The results indicated that the model provided a goodto- acceptable fit to the data, as evidenced by the following fit indices: χ2/df = 2.172, Goodness of Fit Index = 0.91, Adjusted Goodness Fit Index = 0.87, Comparative Fit Index = 0.95, Incremental Fit Index = 0.95, Tucker-Lewis Index = 0.93, Normed Fit İndex = 0.91, and Root Mean Square Error of Approximation = 0.07. The reliability analysis indicated acceptable internal consistency, with Cronbach's α values of 0.88 for the overall scale, 0.86 for the symptom control subscale, and 0.76 for the functionality maintenance subscale.
conclusionThe Cardiac Self-Efficacy Questionnaire can be considered a valid and reliable instrument for assessing cardiac self-efficacy in the Turkish population.
