Data and analyses cross-validation EPICC Tool-it

Source data in file format .dat for the all dataset and for the two subsamples; Mplus input-output files for the EFA and CFA performed.
The multicentre, cross-sectional validation study to which the data belongs aimed to cross-culturally adapt and psychometrically test the Italian version of the EPICC Spiritual Care Competency Self-Assessment Tool for nurses (EPICC Tool-It).
The 28-item EPICC Tool was translated into Italian and culturally adapted following a rigorous methodology. A nationwide survey was conducted. Psychometric evaluation included content validity, structural validity (exploratory and confirmatory factor analyses), construct validity (known group analysis), and reliability using Cronbach's alpha, McDonald's omega, and factor score determinacy.
The sample included 725 nurses (76% female, 80% hospital-based), on average 38.7 years old (SD 11.33), with 14.6 (SD 11.03) years of experience. Confirmatory factor analysis supported a four-factor model (Knowledge of spirituality, Attitudes towards spirituality and spiritual care, Knowledge of spiritual care, and Skills in spiritual care), with a second-order factor for the EPICC Tool-It. Construct validity was supported through known group analysis, showing score variation based on nurses' experience, education, and religiosity. Internal consistency was excellent across all factors and the overall scale.
A valid, multidimensional instrument is provided to assess spiritual care competencies in Italian-speaking nurses. The EPICC Tool-It is suitable for research and practice, facilitating evaluation of self-perceived competencies and educational effectiveness.
Implications for the Profession and/or Patient Care: The use of the EPICC Tool-It by nursing managers, educators, and clinicians is recommended in both clinical and research settings to support education on spiritual care competencies.
