As global migration increases, nurse managers' effectiveness in multi-cultural nursing work environments is crucial due to the rising cultural diversity within healthcare teams. Despite the increasing international recruitment of qualified nurses to address the worldwide nursing shortage, no studies have synthesised the impact of nurse managers' attributes on nurses in multi-cultural nursing teams. Therefore, it was conducted a literature review aimed to synthesise the available literature on how nurse managers' personality traits, competencies, behaviours, and leadership styles influence nurse outcomes in multi-cultural nursing teams. Scoping review conducted according to the Joanna Briggs Institute guidelines to map the relationship or influence of nurse managers' personality traits, competencies, behaviours, and leadership styles on the outcomes of nurses in multi-cultural settings across various clinical environments. Searches were conducted across electronic databases such as CINAHL and MEDLINE, along with grey literature. This review included 39 studies, highlighting 29 personality traits, 9 competencies, 115 behaviours, and 5 leadership styles that impact nurses' outcomes. Key findings emphasise the importance of nurse managers being supportive, culturally competent, and effective communicators, with transformational leadership style being particularly beneficial. These findings provide insights for planning and developing training programmes to equip current and future nurse managers with skills to effectively lead in multi-cultural care settings.
