In today's world, nurses increasingly care for individuals from different cultures. Because culturally sensitivecare can improve patient satisfaction in care, nurses need to develop cultural competence in their practice. Todevelop cultural competence, one option is to build cultural awareness by exposing students to nursing practicesin other cultures through online internationalization-at-home activities. However, little is known about theprocess of cultural awareness development through internationalization activities. Therefore, this qualitativestudy aimed to identify the development process of cultural awareness in nursing students, who participated in aseries of internationalization-at-home activities. A total of 31 nursing students from Australia, Hong Kong, andSweden volunteered to participate in student-led learning groups. Groups consisted of two to four students fromeach university, who engaged in four weekly webinars and online reflections about nursing practice based on acase scenario. Data were collected from participants' ongoing reflective journal entries, and after the webinarsended, from three focus groups. A semi-structured interview guide was used to understand how the internationalization-at-home activities impacted their cultural awareness and knowledge of nursing. Data wereanalyzed using interpretive description. Following four levels of thematic analysis (i.e., comprehension,synthesis, theorizing, reconceptualization), we identified four themes in the development of cultural awareness:1) nurturing reciprocity through comparisons of nursing culture; 2) discovering common ethical values of thenursing profession; 3) developing cultural awareness in nursing ideology and practice; and 4) transformingunderstanding of nursing in the context of their healthcare systems. By the end of the internationalizationactivities, students appeared to have developed relational skills to facilitate their own inner dialogue aboutethical ideals of “self” and “other” in the context of being part of the global nursing community. Future researchshould develop and assess teaching strategies that can further facilitate the four themes in cultural awarenessdevelopment.
