The PechaKucha method will be used to provide training on enteral nutrition. The training content has been prepared in consultation with at least two experts experienced in the field of enteral nutrition and will be implemented after necessary adjustments. To ensure consistency in presentation style, tone, and participant engagement, all presentations will be given by the same researcher. Standardizing the intervention in this way is an important strategy to increase the accuracy of the intervention and minimize variability between sessions. The training will be delivered as a 6-minute 40-second presentation consisting of 20 slides, each slide advancing automatically for 20 seconds. The training content will cover nursing approaches such as the basic principles of enteral nutrition, correct application steps, complications, and necessary precautions in case complications arise.

The scale, developed to measure nurses' self-efficacy in enteral nutrition practices, consists of two sub-factors and 37 items. The five-point Likert scale is evaluated on a scale of "strongly disagree (1)" to "strongly agree (5)". The Knowledge Sub-Factor consists of 20 items (items 1-20); the Practice Sub-Factor consists of 17 items (items 21-37). There are no reverse items in the scale. The minimum total score obtainable from the scale is 37, and the maximum is 185. The minimum-maximum scores for the Knowledge sub-factor are 20-100; the minimum-maximum scores for the Practice sub-factor are 17-85. As the scores obtained from the entire scale and its sub-factors increase, it is inferred that self-efficacy levels in enteral nutrition practices increase. The Cronbach's alpha coefficients for the sections of the scale are 0.92 and 0.91, respectively. The Chronbach Alpha coefficient for the entire scale is 0.94.
