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

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. 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. 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. The OPES is a valid and reliable tool to evaluate the oral presentations of Turkish nursing students.
