AN ALTERNATIVE SCS-SF VERSION? PSYCHOMETRIC VALIDATION OF THE COLOMBIAN SCS-SF

Abstract

This study aimed to assess an alternative version of the Self-Compassion Scale Short Form (SCS-SF) based on data from the first Colombian validation of the form via the item information function (IIF). A secondary analysis was performed to propose the IIF-reduced SCS-SF version using two independent Colombian samples. The study tested 6-factor models, including confirmatory factor models (CFA) and exploratory structural equation modeling (ESEM). The first sample was composed of 918 subjects (original SCS-SF), and the second comprised 853 subjects (IIF-reduced SCS-SF). Both SCS-SF versions showed a fit in a 6-factor correlated model; the IIF-reduced version showed a fit in a bifactor-ESEM model. However, the loadings had specification problems. Given that the IIF-reduced version lacked clear advantages over the original SCS-SF, which fitted a 6-factor CFA (CFI = 0.995, TLI = 0.957, RMSEA = 0.057, SRMR = 0.029), the original version is recommended.
