Methods
This experimental study utilized the five steps of the ADDIE instructional model (analysis, design, development, implementation, and evaluation) to design a mobile app-based cultural care training program. The first three steps involved designing and developing the program, drawing upon Purnell's model for cultural competence and Foronda's rainbow model of cultural humility. In the fourth step, the cultural care training program was implemented in 16 modules among 80 internship nursing students. These students were randomly assigned to either the intervention or control groups, with 40 students in each group. Finally, in the fifth step, the effectiveness of the mobile app-based program was evaluated by administering the Cultural Capacity Scale, and the Foronda Cultural Humility Scale before and one month after the cultural care training. The collected data were analyzed using SPSS22, employing techniques such as paired t-test, chi-square test, and independent samples t-test.
