Adaptation and Validation of the Compassionate Capacity Scale for Portuguese Healthcare Students (CCS-PHS)

Abstract

Compassion is a critical competence for healthcare students. However, there are no tools that measure compassionate capacity during students' training. Recently, the Compassion Capacity Scale (CCS) was developed for health professionals, exhibiting good psychometric properties. The aim of this study was to translate, culturally adapt, and validate the CCS for Portuguese healthcare students. The study was divided into two phases: (1) translation and adaptation of the CCS for Portuguese students in the healthcare field; (2) validation and analysis of psychometric properties. The CCS-PHS showed good internal consistency (Cronbach's α = 0.886), temporal stability (rho = 0.703), and content validity (CVI-i = 1). Criterion validity analysis showed strong correlations between all of the CCS-PHS's dimensions and the chosen reference criteria scale. Construct validity analysis revealed that the CCS-PHS is composed of 17 items, classified into four factors. The differences found in the exploratory factor analysis in relation to the original scale may be due to the life experiences of healthcare professionals when compared to those of students. Our psychometric analysis suggests that the CCS-PHS is a reliable and valid tool to assess compassionate capacity in healthcare students. Knowing the compassionate competence of students is vital for guiding educational strategies, implementing compassion training programs and evaluating their effectiveness, as well as reinforcing key attitudes and behaviors for humanized and ethical healthcare.
