Callista Roy created the Roy Adaptation Model (RAM) in response to an issue from her Professor Dorothy E. Johnson in 1964. The foundational concept is introduced in the Adaptation framework; A Conceptual Framework for Nursing. The RAM was applied by the educators of Mount Saint Mary's College in Los Angeles to organize its curriculum. Roy's Adaptation framework teaches nurses the fundamentals of treating patients including the philosophical approach. Precise descriptions for the mentioned ideas and phrases used in the model are required. Another hurdle in the practice field is time constraints; the obligatory time to fully apply the two components of RAM evaluation may be seen as much more difficult to overcome. This is especially problematic when the bulk of practitioners begin to utilize the RAM and confront the aforementioned obstacle.
