The Reliability and Validity of the Turkish Oral Presentation Evaluation Scale for Nursing Students.

Background and Purpose: In nursing education, students are often expected to make presentations. This study aimed to adapt the Oral Presentation Evaluation Scale (OPES) into Turkish language and investigate its psychometric properties. Methods: This methodological study comprised 311 undergraduate students. The data were analyzed by descriptive statistics, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), Cronbach's alpha (α) coefficient, and item-total correlation. Results: The item-total score correlation coefficients of the scale were between 0.636 and 0.787, and according to the CFA, the factor loads of all items varied between 0.533 and 0.846. The chi-square/standard deviation value, goodness of fit index, comparative fit index, normed fit index, and root mean square error of approximation were 2.056, 0.928, 0.973, 0.949, and 0.058, respectively. Cronbach's α value was 0.951. According to the results of EFA, the scale consists of a two-factor structure in Turkish culture. Conclusions: The OPES is a valid and reliable tool to evaluate the oral presentations of Turkish nursing students.
