The students involved in the intervention group were divided into subgroups, and the simulation was carried out using standardized patients. Each subgroup consisted of two students. Students were asked to practice supine and lateral recumbent positions in each scenario.

The students in the control group were divided into subgroups and practised the supine position and the lateral recumbent position with a high-fidelity manikin. Each subgroup consisted of two students. The applications lasted 5-10 minutes for each group, and after the applications, the debriefing phase was conducted, which lasted 20 minutes.

Nursing students were trained with a standard patient simulation model for position and communication skills education.

Describing the performance scores of the students in the standardized patient group and the high-fidelity simulation manikin group.

The checklist consisted of 20 steps. The student scored "0" if "the step was not applied at all" or "the step was applied incorrectly." If the "step was not fully implemented", it was graded with "1" point, and "if the step was performed correctly and completely," it was graded with "2" points. Checklists were filled out by an independent observer, who was not a researcher. Scores that can be obtained from the skill checklist ranged between 0 and 80, which were converted to 100 points.

Therapeutic Communication Skills Questionnaire for Nursing Students: It is a 7-point Likert-type scale and consists of 16 items and three sub-dimensions. The highest total score that can be obtained from the scale is 112, which shows high therapeutic communication skills.
