Does psychological stress contribute to the onset of breast cancer

For this assignment you will write a literature review based on 5 studies that examine the role of one specific psychological or social factor in either the onset or course of a disease. Please choose a disease of interest to you (e.g., breast cancer, heart disease, asthma, AIDS). Locate 5 studies that examine the role of some specific psychological or social factor in either the onset or course of the disease (e.g., stress, social support, perceived control, Type A Behaviour Pattern). These should all be reports of original findings on a specific study. Although you may cite scholarly published literature reviews and meta-analyses in your paper, these should not be considered one of the five studies you are reviewing. Prepare a literature review based on these five studies. What can you conclude about the role of that psychosocial factor in the disease? Back up your arguments and cite your sources. Please provide either links to the five articles or include pdf’s of them with your assignment. Your paper should be 2.5-3 pages of single-spaced text (excluding references and a title page). References should be included on a separate page attached to the end of your assignment. It is important to have a clear and specific research question that you will answer in your review. A question like “Does stress affect heart disease?” is too broad. What do you mean by “stress”? And what do you mean by “affect”? Are you going to examine the role of stress in causing heart attacks? Or are you going to examine the role of stress in hindering recovery from heart attacks? Or are you going to examine how heart attacks create stress in people’s lives? A more precise research question might be “Does acute psychological stress predict the onset of myocardial infarction (heart attack)?” All the articles you select should investigate the research question you are trying to answer. Your assignment will be graded based on the appropriateness of the articles you select, the clarity of your writing, and the quality of your interpretation and synthesis of the 5 studies. Consider the strengths and limitations of the studies in your review. How do these affect your interpretation of the findings and the conclusions that you can draw? 1inch margin left and right side of the paper, Time New Roman 12 point font.
