Development and Validation of the Therapeutic Communication Scale in Nursing Students

This study aimed to develop and validate a scale for measuring the therapeutic communication of nursing students. The scale development and evaluation study was conducted based on the scale development guidelines of DeVellis. A 47-item instrument was developed based on a review of the literature and interviews with 16 experts. Content validity was evaluated by ten nursing scholars, and the number of items was reduced to 35. The scale was administered to 352 nursing students from three regions in South Korea in 2022. Exploratory factor analysis and confirmatory factor analysis were performed on the scale items. Convergent validity, discriminant validity, and internal consistency reliability of the scale were evaluated. The factor analysis resulted in 15 items and two factors: relationship building and problem solving. Confirmatory factor analysis and evaluation of convergent and discriminant validity provided support for the validity of the two-factor Therapeutic Communication Scale in nursing students. The total scale demonstrated good internal consistency, with a McDonald's omega (omega) of 0.89. The Therapeutic Communication Scale is a reliable and valid measure that can be used to assess nursing students' therapeutic communication competence related to patient-centered nursing and provide foundational data to improve such skills.
