Mayo High Performance Teamwork Scale: Turkish Validity and Reliability Study

Purpose: This study aimed to translate the Mayo High Performance Teamwork Scale (MHPTS) into Turkish, ensure its cultural adaptation, and evaluate its psychometric properties among nursing students.Methods: This methodological research was conducted between January 2022 and January 2023 with nursing students enrolled in a surgical nursing program. The translation and cultural adaptation process followed the standardized forward–backward translation method recommended by Beaton et al. Expert review was conducted to determine content validity, and a pilot test was performed with students experienced in simulation-based learning. Reliability was assessed using the test–retest method, and internal consistency was evaluated using Cronbach’s alpha. Construct validity was examined using the Rasch measurement model, including item fit statistics, person and item reliability indices, and separation values.Results: A total of 339 scale evaluations were used in the study. The Cronbach’s alpha coefficient of the Turkish version of the MHPTS was 0.839, indicating high internal consistency. Rasch analysis demonstrated acceptable INFIT/OUTFIT mean-square values for all items, supporting the unidimensional structure of the scale. Rasch item and person reliability coefficients were 0.95 and 0.73, respectively. The mean total score on the scale was 26.67±4.34, reflecting positive perceptions of teamwork and non-technical skills during simulation-based learning experiences.Conclusion: The Turkish version of the MHPTS is a valid and reliable instrument for evaluating non-technical skills and teamwork performance among nursing students in simulation-based surgical nursing education. The scale can be used to assess the effectiveness of educational interventions, identify areas for improvement in team-based competencies, and support the development of patient safety culture in clinical education environments.
