Final answer:
The PEO Model was revised to the PEOP Model by Sue Baptiste, Mary Law, and Carolyn Baum to emphasize performance in context as an essential outcome of the person-environment-occupation interaction.
Step-by-step explanation:
The PEO Model (Person-Environment-Occupation) was revised to make the PEOP Model (Person-Environment-Occupation-Performance) by Sue Baptiste, along with colleagues Mary Law and Carolyn Baum.
The PEOP Model is an expansion of the original PEO Model, and it emphasizes the importance of performance in context as an outcome of the interaction between the person, environment, and occupation.
While the PEO model was a collaborative development by various theorists, it was the work of these particular researchers who revised and extended it to create the PEOP model, emphasizing a more client-centered approach and the importance of engaging in meaningful occupations.
