"self-concept mode" which I'm reading refers to "level of anxiety, involvement in self-care, relationship with family and friends and general outlook."

Did you google that? If so I'm very impressed!

We covered the SOAP concept in another class, and we've come back to it, but none of the notes on Roy's theory mention it. So good point–I can double check and if I still don't find any reference, I can put that as 'something that's missing.'
