How do cultural logics direct voice in an academic health system? A cross-sectional study of cultural orientations and speaking-up intentions

Background As academic health systems (AHS) become more integrated and specialized, diversity is often framed in terms of professions, roles, and disciplines, while cultural diversity shaping how healthcare professionals (HCPs) interpret hierarchy, voice, and accountability remains under-recognized. The horizontal–vertical individualism–collectivism framework offers one lens for understanding how individuals approach speaking up, particularly in rapidly evolving AHS where organizational norms are still forming. This study examined associations between cultural orientations and speaking-up intentions across multiple reporting routes in a multicultural AHS. Methods A clarification cross-sectional survey was conducted among HCPs in a multicultural AHS in the United Arab Emirates. Cultural orientations were measured using the horizontal–vertical individualism–collectivism framework. Speaking-up intentions were assessed across differentiated reporting routes (internal, external, identified, anonymous, formal, and informal). Results A total of 153 HCPs participated. Confirmatory factor analysis supported the four-dimensional cultural orientation structure (CFI = 0.956; TLI = 0.947). Vertical collectivism (VC) was positively associated with internal ( r = 0.260, p = 0.001) and identified ( r = 0.263, p < 0.01) speaking-up, and negatively associated with anonymous reporting ( r = −0.297, p < 0.001). In contrast, vertical individualism (VI) was associated with greater inclination toward external reporting ( r = 0.346, p < 0.001). Regression analyses showed that VC predicted internal ( B = 0.223) and identified ( B = 0.395) reporting, and negatively predicted anonymous reporting ( B = −0.237), while VI predicted external reporting ( B = 0.401). Age was negatively associated with anonymous reporting ( B = −0.237), and gender predicted formal reporting ( B = 0.343). Formal and informal routes were not strongly explained by cultural orientations. Conclusion Speaking up in multicultural AHS may be understood not as a uniform willingness to raise concerns, but as a culturally situated practice shaped by different routes of voice. Cultural orientations influence how concerns are channeled, with VC aligning with accountable internal voice and VI with more autonomous external escalation. Age and professional status may function as forms of social capital, shaping willingness to attach identity to voice. External reporting may signal moral strain, diffusion of responsibility, or reduced trust in organizational systems, while structured hierarchies may provide pathways for navigating ambiguity.
