Nursing students who were in the experimental group during the application phase of the study were given training to develop their intercultural sensitivity levels based on Leninger's Intercultural Nursing Theory. Data were collected at the beginning of the four-week online training, at the end of the training, and one month after the training.

No application was made to the control group within the scope of the research. Data were collected simultaneously with only the experimental group.

The educational content of the research was created by the researcher in line with the literature and expert opinions and covers the following topics.

Educational subjects

1. Culture and Concepts Related to Culture
2. Culture/Cultural Characteristics and Cultural Elements in Terms of Social Structure
3. Cultural Factors Affecting Health and Disease
4. Concepts and Practices Related to the Field of Study

The training is an online training and continued via video conference, and a session invitation was sent to the participants before each session. In addition, after the training, brochures containing the training topics of each week were prepared and delivered to the participants. The trainings were conducted by the researcher in a total of four sessions (each session 20 minutes) once a week during the training process. During the training, the questions of the participants were answered.

The scale was developed by Chen and Starosta and was adapted to Turkish in 2010. It consists of twenty-four items and includes five emotional dimensions necessary to measure intercultural sensitivity. The scale has five dimensions: responsibility in communication, respect for cultural differences, self-confidence in communication, enjoying communication, and being careful in communication. The scale has a 5-point Likert-type rating. As the score obtained from the scale increases, the level of sensitivity increases. The Cronbach's alpha value of the scale was determined as 0.90.
