If you find one really awesome book or journal that fits your topic perfectly, try looking in the works cited/bibliography/reference list at the end of it. This should contain many more books and journals that are about your topic as well.
APA format is used by researchers in the social sciences field, and requires in-text citations as well. It ends the paper with a “references” page, and may also have section headers between body paragraphs.
An easy way to develop your thesis is to make it into a question that your essay will answer. What is the primary question or hypothesis that you are going to go about proving in your paper? For example, your thesis question might be “how does cultural acceptance change the success of treatment for mental illness?” This can then determine what your thesis is - whatever your answer to the question is, is your thesis statement.
Research paper conclusion. Now, it’s time to wrap it up. Most research papers conclude with a restated thesis statement. Present your thesis again, but reword it. Briefly summarize the points you’ve made. Take a moment to explain why you believe those points support your case. If your research is inconclusive, take a moment to point out why you believe this topic bears further research.
