Change theories, contrast and comparison

Compare and contrast two change theories, and determine which theory makes the most sense for implementing your specific EBP project. 

Why? Has your mentor used either theory, and to what result? 

This is for a nursing school assignment. 

My project is catheter related urinary tract infection(UTI), and the theory supposed to be a nursing field. I need it as soon as possible. At least two references (peer reviewed research paper or a 1 book and 1 research paper).
