This study describes the cross-cultural validation and psychometric evaluation of the Spiritual Care Competence Scale – Brazilian Portuguese version. This reliable and valid instrument is recommended in the literature to measure the outcomes of the education process in the development of spiritual care competences.

This is a cross-sectional validation study following the stages proposed by Beaton et al.: translation into Portuguese, back translation into English, expert committee review for semantic equivalence, assessment of the clarity of the pre-final version, and evaluation of the psychometric properties of the final version in Portuguese. Health professionals working at a public hospital in South Brazil participated in the different stages of this study.

Regarding internal consistency, total Cronbach's alpha was 0.92 and the mean inter-item correlation was 0.29. The test-retest procedure showed no statistically significant differences in the six subscales. The intraclass correlation coefficient ranged from 0.67 to 0.84, demonstrating the stability of the scale.

The results support the psychometric quality of the scale and indicate that the adapted instrument is a valid and reliable scale with good internal consistency for measuring spiritual care competencies of health professionals in Brazilian healthcare settings.
