How to Write the Module 1 Research Paper and Discussion Post
Two to three pages. Multiple sources woven into one argument. A discussion post with ABC Approach peer replies. This guide walks through exactly what each deliverable needs — what health psychology actually is as a field, how to build a synthesis paper around it, and how to write peer replies that actually earn marks.
Module 1 sets the foundation for the entire course. The research paper asks you to define and situate health psychology as a field — what it studies, how it differs from other branches of psychology and medicine, and why the biopsychosocial model matters. The discussion adds a peer engagement layer. Both deliverables reward specificity over breadth. Here’s exactly how to approach each one.
What This Guide Covers
Module 1 Deliverables at a Glance
There are two separate tasks here, and they run on different tracks. Don’t mix them up or treat the discussion post as an extension of the paper.
Module 1 Assignment Checklist
What Health Psychology Actually Is
Before you can write a paper defining the field, you need to understand it clearly yourself. A lot of students conflate health psychology with clinical psychology or with public health. They’re related, but distinct.
Health psychology is the scientific study of how biological, psychological, and social factors influence health and illness. It asks: why do some people get sick and others don’t, even in similar conditions? How do stress, beliefs, relationships, and behavior affect physical health outcomes? And how can psychological science help people change health-relevant behaviors?
Three Things Health Psychologists Study and Do
Your paper needs to convey that health psychology is a research field, a clinical practice area, and a public health resource. These are three distinct roles, and most introductory papers only address one.
Research: Investigating how psychological factors (stress, personality, coping, social support) affect physical health outcomes — cardiovascular disease, immune function, cancer progression, recovery from illness.Clinical practice: Working with patients managing chronic illness, pain, or health behavior change — in hospitals, primary care, rehabilitation, and specialty settings.
Public health and prevention: Designing and evaluating interventions to promote healthy behavior and prevent disease at population level — smoking cessation, obesity prevention, medication adherence.
The American Psychological Association’s Division 38 defines health psychology as “the aggregate of the specific educational, scientific, and professional contributions of the discipline of psychology to the promotion and maintenance of health, the prevention and treatment of illness, and the identification of etiologic and diagnostic correlates of health, illness, and related dysfunction.” That’s the formal definition — useful to cite. But your paper needs to go beyond citing a definition and actually explain what it means. Break it down. Use examples. Connect it to the biopsychosocial model.
| How Health Psychology Differs From… | The Key Distinction | Why It Matters for Your Paper |
|---|---|---|
| Biomedicine / Biomedical Model | Biomedicine focuses on biological causes of disease. Health psychology incorporates psychological and social factors alongside biology. | The contrast between the biomedical and biopsychosocial models is the central conceptual move in most introductory papers. |
| Clinical Psychology | Clinical psychology primarily addresses mental health conditions. Health psychology focuses on the interface between psychological processes and physical health. | Clarifying this distinction shows you understand the field’s unique scope. |
| Public Health | Public health is population-level and multidisciplinary. Health psychology is specifically the psychological science contribution within that broader field. | Helps you position health psychology as a distinct discipline with a specific methodological identity. |
| Behavioral Medicine | Behavioral medicine is broader and interdisciplinary (medicine, sociology, education). Health psychology is the specifically psychological subdiscipline within that space. | Relevant if your course text distinguishes these — worth a sentence in the paper if so. |
The Biopsychosocial Model — Your Anchor Concept
Almost every “What is Health Psychology” paper needs to address the biopsychosocial model. It’s the theoretical foundation of the field. Get this concept right and your paper has a strong spine.
Three Levels of Influence on Health — Not One
Proposed by psychiatrist George Engel in 1977 and published in Science, the biopsychosocial model argued that health and illness cannot be explained by biological factors alone. They result from the interaction of biological factors (genetics, physiology, immune function), psychological factors (thoughts, emotions, beliefs, behavior, stress), and social factors (relationships, socioeconomic status, culture, environment). All three levels interact — and health psychology operates primarily at the psychological level while accounting for the other two.
Why cite Engel: Your course text will reference this model, but citing the original 1977 article in Science signals that you went to the primary literature, not just the textbook paraphrase. Engel, G. L. (1977). The need for a new medical model: A challenge for biomedicine. Science, 196(4286), 129–136. This is a verified, peer-reviewed primary source for the foundational model of your entire field.The Body’s Physical Systems
Genetics, neurochemistry, immune function, physiology, age, sex. The part medicine had always focused on. Health psychology doesn’t dismiss it — it adds the other two levels alongside it.
Mind, Behavior, and Emotion
Stress, coping styles, beliefs about illness, personality, emotional regulation, health behaviors (smoking, diet, exercise, sleep). This is where health psychology does most of its work.
Context, Relationships, Culture
Social support networks, socioeconomic status, cultural health beliefs, access to healthcare, environmental stressors. Health doesn’t happen in isolation — social context shapes both risk and resilience.
A weak paper names the three parts of the biopsychosocial model and moves on. A strong paper explains how they interact — how chronic stress (psychological) elevates cortisol (biological) which suppresses immune function, increasing illness risk, and how social isolation (social) amplifies stress by removing buffering relationships. The interaction is the model’s actual argument. Show that you understand it, don’t just name it.
How to Structure the 2–3 Page Research Paper
Two to three pages is tight. Every paragraph needs to pull its weight. There’s no room for a long wind-up or a conclusion that just repeats the introduction.
Introduction — Define the Field and Set Up Your Argument (½ page)
Open with what health psychology is and why it matters as a distinct field. Introduce the biomedical vs. biopsychosocial contrast as the central conceptual tension. End with a clear thesis that tells the reader what your paper will argue or demonstrate — not just “this paper will discuss health psychology” but a specific claim about the field’s scope, significance, or approach.
The Biopsychosocial Model and What It Changed (¾–1 page)
This is the theoretical core. Explain the model, contrast it with the biomedical model, and show — with an example — how thinking about health changed when psychology entered the picture. Use at least two sources here. The interaction between the three components is more important than defining each one in isolation.
What Health Psychologists Study and Do (¾–1 page)
Cover the field’s major research and practice areas: stress and illness, health behavior change, chronic disease management, pain, patient adherence, health promotion. You can’t cover all of them in depth — pick two or three and connect them back to your thesis. Use sources that show real research findings, not just descriptions of what the field “aims to do.”
Conclusion — Why the Field Exists and Why It Matters (¼–½ page)
Bring the argument together. Why does health psychology need to exist as a separate discipline? What gap does it fill that biomedicine alone can’t? Connect back to your thesis. Don’t introduce new material here — consolidate what you’ve already argued.
Synthesising Multiple Sources — What That Actually Means
The assignment says to demonstrate your ability to utilize research from multiple sources into a single, cohesive paper. That word — cohesive — is the key. It means the sources are woven together around your argument, not lined up separately.
What Synthesis Is NOT
Writing three separate paragraphs, each one about a different source. “According to Smith (2019)… According to Jones (2021)… According to Brown (2020)…” That’s an annotated bibliography dressed up as a paper. Each paragraph summarizes one source and then stops. There’s no connection, no argument, no integration.
What Synthesis Looks Like
Organizing by idea, not by source. Each paragraph makes a single claim about health psychology — then draws on two or more sources to support it. “The relationship between stress and immune function is well documented. [Source A] found X, while [Source B] extended this to show Y, suggesting that Z.” One point. Multiple supporting sources. One cohesive paragraph.
Research Databases That Cover Health Psychology Well
PsycINFO is the primary database for psychology — use it first. PubMed covers the health and biomedical side and is particularly strong for biopsychosocial research. Google Scholar works for finding peer-reviewed articles quickly, but verify the source before citing. For a 2–3 page introductory paper, three to four peer-reviewed sources plus your course text is appropriate.
Search terms that work: “health psychology overview,” “biopsychosocial model review,” “psychological factors chronic disease,” “health behavior change psychology,” “stress and illness mechanisms.” Narrow by peer-reviewed, full text, last 10–15 years. The Engel (1977) foundational article is an exception to the recency rule — cite it directly when discussing the biopsychosocial model’s origins.Engel, G. L. (1977). The need for a new medical model: A challenge for biomedicine. Science, 196(4286), 129–136. This is the foundational primary source for the biopsychosocial model — still cited in contemporary literature. It’s available through most university library systems. For the APA Division 38 definition of health psychology, cite: American Psychological Association. (n.d.). Health psychology. Division 38. https://www.apa.org/ed/graduate/specialize/health
The Discussion Post and ABC Approach Peer Replies
These are two separate tasks. Your original post and your peer replies. Both are graded. The peer replies are where most students underperform — not because they didn’t engage, but because they didn’t use the ABC Approach correctly.
A Focused, Substantive Response to the Discussion Prompt
Your original post isn’t a mini version of the research paper. It should be focused and conversational — but academically grounded. Engage with a specific aspect of health psychology that the module prompt raises, support it with at least one source, and end with a question or observation that invites your peers to respond. That last move sets up more productive ABC replies.
Length: Most programs expect 150–250 words for an original discussion post. Check your rubric. Longer isn’t automatically better — a focused 200-word post with one well-cited claim and a genuine question beats a sprawling 400-word summary of the chapter.What Your Peer Said
Demonstrate that you actually read their post. Reference a specific point they made — not “great post” and not a vague restatement. Name the idea: “You made an interesting point about how stress affects cardiovascular health, particularly the link to cortisol you described…”
Add Evidence or a Related Idea
Extend what they said. Bring in a piece of evidence, a finding from a study, a related concept from the course material, or a real-world connection that deepens or complicates their point. This is the substantive part of the reply. One well-supported extension beats three vague ones.
Something New to the Conversation
Add a question, a different angle, a counterpoint, or a real-world application that wasn’t in their post. This keeps the discussion moving. A good contribution makes your peer want to respond — it’s not a conclusion, it’s an opening.
“Great post! I really enjoyed reading your thoughts on health psychology. I agree that the biopsychosocial model is important.” That’s not ABC — it’s three sentences of filler. It acknowledges nothing specific, builds nothing, and contributes nothing. The grader can see it in under five seconds. Write replies that demonstrate you read and thought about your peer’s specific argument.
APA Format for the Research Paper
Paper Formatting Basics (APA 7th Ed.)
- 12pt Times New Roman or 11pt Calibri
- 1-inch margins on all sides
- Double-spaced throughout, including references
- Running head on every page (title + page number)
- Title page: paper title, your name, institution, course, date
- Reference list starts on a new page
- Hanging indent on all reference entries
In-Text Citations to Get Right
- Every claim drawn from a source needs a citation at the claim, not the end of the paragraph
- Paraphrase rather than direct quote — APA favors paraphrase in research papers
- Direct quotes need page or paragraph number: (Engel, 1977, p. 130)
- Two authors: cite both every time — (Smith & Jones, 2020)
- Three or more authors: first author + et al. — (Brown et al., 2019)
- APA organization as author: (American Psychological Association, n.d.)
A 2–3 page paper in APA format (double-spaced, 12pt Times New Roman, 1-inch margins) runs roughly 500–750 words of body text. That’s not a lot. Plan your content carefully. A title page and reference list add pages that don’t count toward the body — your 3-page limit usually means 3 pages of actual writing, not including those elements. Check your assignment instructions to confirm whether the title page and references are included in the page count.
Mistakes That Cost Marks
Defining Health Psychology in One Sentence and Moving On
Giving a textbook definition without unpacking what it means in practice. The grader knows the definition. They want to see that you understand the field’s scope, its history, and why it exists as a separate discipline.
Define It, Then Show It
After defining the field, immediately illustrate it. What does a health psychologist actually study? What does the biomedical model miss that health psychology addresses? One concrete example makes the definition land.
Describing the Biopsychosocial Model Without Showing Interaction
Listing biological, psychological, and social as three separate boxes without explaining how they interact. The model’s whole point is that these factors don’t operate in parallel — they affect each other.
Walk Through an Interaction Example
Pick one health outcome — stress-related illness, cardiovascular disease, chronic pain — and show how biological, psychological, and social factors interact to produce it. One good example does more than a paragraph of abstract description.
Treating the Discussion Reply as Filler
“Great insights! I found your post very informative and I agree with your points about health psychology.” This earns minimal credit. The ABC Approach requires substantive engagement — specific acknowledgment, evidence-based extension, genuine contribution.
Reference a Specific Claim, Then Build It
Name exactly what your peer said. Add one piece of supporting or complicating evidence. End with a question that invites further discussion. Three moves, each distinct. Even 150 words done this way earns full marks for peer engagement.
Summarizing Each Source Separately
Writing a paragraph per source instead of organizing by idea. The assignment says multiple sources into a single cohesive paper — that means synthesis by argument, not source-by-source annotation.
Organise by Idea, Not by Source
Each paragraph makes one claim about health psychology. Two or more sources support that claim within the same paragraph. The argument drives the structure; the sources serve the argument.

Psychology Writing Services Get StartedStart With What the Field Is Trying to Solve
The best papers on this topic don’t start with a definition — they start with a problem. Before health psychology existed as a formal field, medicine had a gap. People with identical biological conditions had wildly different outcomes. Stress made people physically sick. Behavior drove half of all preventable deaths. Biology alone couldn’t explain it.
Health psychology exists because that gap needed a science. The biopsychosocial model gave that science a framework. Write from that starting point — the problem the field was built to address — and your paper will have a real argument running through it, not just a description of what health psychologists do.
Two to three pages is genuinely tight. You don’t have room to be vague. Every sentence should advance the argument. And for the discussion replies — short, specific, and structured beats long and meandering every time. Use the ABC moves deliberately, not as decoration.
