The Spiritual Supporter Scale as a New Tool for Assessing Spiritual Care Competencies in Professionals: Design, Validation, and Psychometric Evaluation

This study aimed to design, validate and standardize the Spiritual Supporter (SpSup) Scale, a tool designed to assess competency to provide spiritual care including knowledge, sensitivity to spiritual needs and spiritual support skills. This instrument can be used by all those engaged in or training for caregiving roles. The study was conducted in Poland in the Polish language. The SpSup Scale demonstrates high overall reliability (Cronbach’s α = 0.88), a satisfactory diagnostic accuracy (0.79), and a satisfactory discriminatory power of the items. Given the psychometric properties of SpSup Scale demonstrated here, the scale is recommended for the assessment of the competency to provide spiritual care in both clinical and research settings in Poland.
