I am nearing the end of my doctoral studies by distance ed at the University of South Africa -- UNISA (Health Sciences). The degree is a D Litt et Phil -- Doctor of Literature and Philosophy. As far as I can tell there are very few nurses in the US with this degree. (I have located just one.)
This is a "thesis only" program for the doctorate, and I must say, I have enjoyed the research immensely and feel like I have gotten a lot of support from my advisors. I'd love to hear with anyone else with experience at UNISA.
