Validity and Reliability of the Turkish Version of the Spirituality Instrument-27 (SpI-27©).

Introduction: This methodological study aimed to adapt the Spirituality Instrument-27 (SpI-27©) to the Turkish language and culture. Design: The psychometric study was carried out with 267 individuals who were hospitalized in the cardiology clinic and who were diagnosed with a chronic disease. Data collection tools were the demographic questionnaire and the SpI-27©. The Statistical Package for Social Sciences was used for data analysis and confirmatory factor analysis. Results: The Kaiser-Meyer-Olkin index was 0.848 and Bartlett's test of sphericity was statistically significant ( p  = 0.000). The root mean square error of approximation was 0.05, the standardized root mean squared residual was 0.04, the adjusted goodness-of-fit index was 0.87, the goodness-of-fit index was 0.92, the nonformed fit index was 0.91, and the comparative fit index was 0.90. Connectedness with others accounted for 38.24 of the total variance, self-transcendence accounted for 11.71, self-cognizance accounted for 10.56, and conservationism and belief accounted for 9.82 of the total variance (total variance was 70.34%). The highest item factor loading of the scale was 0.812 and the lowest one was 0.398. Cronbach's alpha coefficient of the scale was 0.927. Conclusion: This measurement tool will enable researchers to plan and implement nursing interventions accurately and effectively by assessing the spiritual needs of individuals with nonmalignant chronic diseases. The use of this tool in different languages can help diagnose the spiritual needs of nurses working with multicultural and multilingual patients.
