Hi Vit1825
That GRE exam is definitely not a great indicator of success in a Grad program. I took the LSAT test before taking the GRE and did quite a few practice exams (mimicking the natural environment and timing and all). I know the first few times I did this, the psychological ramifications of that darn time clock did me in and I did poorly. By the time I took the GRE I had already been beaten badly by the LSAT experience. I agree that the GRE is really an indicator of memory and sanity under pressure.
As for applying to other Masters, my MPH was not really research based and instead focused on the pragmatic practice of the health delivery system. Although valuable, I do not think I came out of it confident in doing communications research. However, I can definitely run a company LOL. I also fear I will not get accepted into a PhD program and have to anticipate how to make my background better to try again another day.
As for my research interest... I have so many and hope to figure out a focus in school. I am interested in researching how visual media is used to raise awareness of communicable disease and how people conceptualize the disease individually, in particular communities, in policy as a result of that media. (Basically, Media as a social force as it pertains to Health). Also, I am interested in understanding how social media and technology modify health behavior specifically as it relates to the emerging field of Global Medical Tourism. Lastly, since I work for an Electronic Medical Record Company and its getting much support due to the HITECH act, I'd like to research how EMR is affecting the health industry in some way... haven't figures this out yet and EMR is not my favorite subject.
As for USC, I have heard they have a well-funded program but I am suspicious of the quality. I don't see that many people applkying to it either. On a more positive note, I heard that they are extending the PhD deadline indefinitely. It says they are still accepting late applications: http://ascambassador1.usc.edu/Prospective/News.aspx This is the link for USC admissions news. Call them soon and see if you can try again.
What other schools have you applied to?
