... [Show full abstract] psychometric properties of a social competence scale and to assess the overall tendencies of pre-service teachers in this domain. The scale was developed based on four dimensions: attitudes, communication, adaptation, and professional orientation. Factor analysis confirmed a unidimensional model, indicating a coherent construct underlying the instrument. Item characteristics were examined using the Polytomous Item Response Theory with the Partial Credit Model. The results showed that the scale possessed strong item discrimination and appropriate item difficulty levels, ranging from −1.64 to 0.22. The social competence levels of pre-service teachers ranged from −0.87 to 0.69, suggesting moderate variability in their social adaptability and readiness. These findings support the instrument’s utility for assessing and enhancing social competence in teacher education programs.
