RESUMO
BACKGROUND: The evaluation of spiritual requirements in patients can facilitate the delivery of spiritual care as an essential element of holistic healthcare. The objective of this research was to develop and evaluate the psychometric properties of a questionnaire on patients' spiritual needs in medical-surgical hospital settings. METHODS: This research utilized an exploratory sequential design, involving the creation of a pool of items through both inductive and deductive methods. The questionnaire's psychometric properties were then assessed using various techniques, such as face and content validity, item analysis, construct validity, internal consistency, stability, confirmatory factor analysis, and the Gradual Response Model of Samejima. The data analysis was conducted using MPLUS software, version 5.1. RESULTS: The study's results showed that a four-factor structure (interpersonal connectedness, relationship with God, transcendence, and peaceful environment) with 43 items was successfully extracted through exploratory factor analysis. The confirmatory factor analysis supported the findings of the exploratory factor analysis. The Cronbach's alpha coefficients for the scale and factors ranged between 0.83 and 0.95. Furthermore, the interclass correlation coefficients for the scale and factors were between 0.89 and 0.96. CONCLUSIONS: The questionnaire designed in this study is a reliable and valid instrument that can be utilized by healthcare, educational, and research institutions to evaluate the spiritual needs of patients in medical-surgical hospital settings.
