As a SDSU nursing student, your ILLiad access is throught the Wegner Center (https://usd.illiad.oclc.org/illiad/WS$/logon.html)

ILLiad is one option to access the thesis.  Also, the fullt-text (PDF format) is also available on the Proquest Dissertation and Thesis darabase.  SDSU and USD have this database.  I recommend accessing it through the SDSU library.
