The introduction of a research paper written in APA style should introduce the topic being discussed, provide context and a rationale for the topic, and present the thesis statement. The goal of the introduction is to explain to the reader why they should care about this topic and give them a sense of the overall direction of the paper. Here are some guidelines on effectively writing an APA style introduction:
Start with a hook. The very beginning of the introduction should grab the reader’s attention and introduce the general topic area. You can use a relevant quote, statistic, question, anecdote, or other device to engage the reader. For example, if writing on how social media affects adolescent well-being, you could start with an interesting statistic on teen social media usage. This immediately sets the context for the reader.
Provide background on the topic. After introducing the broad topic, you’ll want to give context to help the reader understand why it matters or what existing knowledge has already been established. You may review past research on the topic, define key terms, discuss demographic/societal contexts, outline the history of the field, or look at current events. This background leads into why your specific research question is important to study. Continue providing just enough context so the reader understands the significance without overwhelming them early on.
State the purpose and rationale. Now you’ll want to directly state the purpose and rationale for your research. Clearly explain why exploring this specific research question or problem is important and what it may add to existing knowledge. You can point out gaps or limitations in previous research, changing times or societal needs, implications for theory or application, or other factors that make investigating this question worthwhile. The rationale should convince the reader your research deserves their time and attention.
Present the research problem/question. APA style calls for a clear, concise statement of the specific research problem/question under investigation. This is usually one to two sentences and directly flows from the rationale. For instance, if arguing more research is needed on how social media shapes identity development in teens, your actual research question may be: “How does frequency and types of social media use relate to measures of identity development in adolescents ages 14 to 18?”
Hypothesize outcomes. Finally, you’ll want to present your hypothesis or hypothesized outcomes for the study. In a quantitative study, you’d state the expected significant relationships between variables in your research question. For qualitative research, you may hypothesize certain patterns or themes you expect to emerge from the data based on past literature. In either case, the hypotheses tie your specific research to your broader purpose and rationale.
To summarize and reinforce why this research matters, conclude the introduction with a thesis statement. The thesis should be a one sentence summary of the main argument or findings you expect to arrive at through conducting this study, incorporating the key elements of research problem/question and hypothesized outcomes. With a strong introduction, your reader now understands the overarching topic, why exploring this particular research question is meaningful, and where your study aims to go. The rest of the paper will then provide evidence and rationale for addressing your stated thesis.
With all of these components – a hook, background, rationale, research question, hypotheses, and thesis statement – the reader has the appropriate context and insight to understand and follow the trajectory of your study. Remember that not all components need to be lengthy. Focus on providing concise yet thorough explanations to answer why this study is needed and where it aims to contribute new insights. A well-structured APA introduction sets the foundation for evaluating the quality, logic, and implications of your research methodology and results. With practice, you can craft introductions that effectively engage the reader and communicate the significance of your unique research perspective.
