Roy, a professor and nurse theorist at the William F. Connell School of Nursing in Boston College, is best known for development of the Roy Adaptation Model of Nursing and leadership for knowledge-based practice. At least 350 research publications are studies based on the model. Lecture commitments have taken Roy to 31 countries on five continents, and the Roy Adaptation Association has five international chapters. As early as 1987, an estimated 10,000 nurses had studied in schools where the curricula used the Roy Adaptation Model. The impact of the model on practice continues, with healthcare agencies using it in designing the strategies for Magnet Status. Roy has more than 150 publications, including 11 books (two of which are award-winning) with translations in 12 languages. She has received 42 research and training grants covering a wide range of topics, including neuroscience. At the Connell School of Nursing, she was part of a team initiating a Ph.D. program in nursing that graduated 130 students in the first 17 years. Among her many honors, Roy was named a Living Legend by the American Academy of Nursing.
