PsyD4Me,
I am finishing up my MPH this semester.
Public health and clinical psychology are independent professions, with the former focusing on population-level health, and the latter on clinical research, and the assessment, diagnosis, and treatment of behavioral health disorders. However, some degree of overlap exists between the professions, as you may pursue advanced research training in both fields. Public health is so diverse that you could pretty much design your own curriculum. Oftentimes, you will find that your personal interests can shape your research direction. For example, I knew coming into my MPH program that I wanted to pursue research in psychiatry. I have been fortunate enough to find a research mentor who encouraged me to incorporate my public health skills in conducting research in this area. Some people call this combination "public mental health" or "mental health." Regardless, it has allowed me to pursue research that combined elements of two burgeoning areas of inquiry.
I am looking into clinical psychology programs because I am interested in pursuing a career in which I may combine my interest in research with clinical practice. I considered medical school, but find it hard to imagine eight years without research! I also enjoy teaching, and hope to ultimately work in an academic setting. My public health training has incredibly enriched my understanding of clinical research, epidemiology, and public mental health, and has provided me with the opportunity to hone my research skills and publish five papers. This kind of experience, I hope, will only accentuate my applications to PhD programs in clinical psychology.
In short, the MPH can be a unique, although somewhat circuitous, way to begin a career in clinical psychology. More importantly, if you decide that you really enjoy public health, you can actually get a job with an MPH! An MA in Psychology is pretty much useless, unless you want to teach high school psychology.
Hope that covers it. Let me know if you have any additional questions.
