Aim: To understand the person-centred care (PCC) practice patterns of mental health nurses in one Atlantic Canadian province. Background: There is emphasis on PCC within mental health services, yet, PCC is often poorly understood and operationalized by mental health care professionals. Mental health nurses’ person-centred practices remain unclear, as there is limited research on their practices. Design: The Person-centred Practice Framework (McCormack & McCance, 2016) was the theoretical framework for this concurrent mixed methods study. The quantitative portion of the study was a descriptive cross-sectional design and both interviews and participant observation comprised the qualitative portion. Interpretive description, a nursing methodology, guided the qualitative components of the study. In the integration phase, the analytic technique of merging established the alignment among complementary data within the three sets of study findings. Methods: Seventy Registered Nurses across one Atlantic Canadian province completed the survey package consisting of  the person-centred practice inventory (Slater et al., 2017) and 13 demographic and work-related questions. Interviews occurred with eight individuals who had received recent inpatient mental health care in the province. Thirty-six hours of participant observation were conducted on three adult inpatient mental health units. The Pillar Integration Process, a four-stage procedure designed to integrate qualitative and quantitative data using joint display tables, guided the integration. Results: Three patterns were developed from the integrated data: 1) mental health nurses maintain a separation from patients and often deliver nursing care from a distance, 2) mental health nurses practice in an organizational culture that supports the status quo, which is not person-centred care, and 3) when mental health nurses and individuals co-engage in person-centred moments, the results are inspiring and foster hope.  Conclusion: Nurses face organizational and personal barriers in their delivery of person-centred care. Although person-centred moments were infrequent, they are valued by those who receive care.
