Nonverbal communication is an inevitable art to be effectively mastered by nurses. Nurse nonverbal communication has many benefits when it is effective. For instance, nonverbal communication is important to convey affective and emotional information, and demonstrate respect for and build therapeutic relationships with older patients. As the older population is growing fast worldwide, effective nonverbal communication with older patients is an essential skill for nurses and will improve patients’ satisfaction and the quality of care. Therefore, this article presents a model to guide effective nonverbal communication between nurses and older patients. A Grounded Theory approach guided the study. Data were collected between July 2018 and January 2020 through overt participant observations and individual interviews. Purposive and theoretical sampling were used to select 13 clinically experienced nurses, 4 nursing students, and 8 older adults. Data analysis encompassed open coding, axial coding, and selective coding. The results showed that effective nonverbal communication emerged as the co-phenomenon hinged within context and/or environment and is influenced by certain factors. This model, which is in support of person-centered communication and care, advocates for effective nonverbal communication between nurses and older patients.
