Depression is the disorder Paper 3 sources come back to most often, usually with a graph of prevalence attached. This page takes one condition and follows it across cultures — how it is felt, how it is described, how it is treated, and why those tidy country comparisons are far shakier than they look.
📘 What you need to know
Depression appears in every society studied, but the symptom emphasis shifts — body complaints in some settings, guilt and low mood in others.
A somatic presentation means distress reported mainly through the body: pain, tiredness, sleep problems.
Reported prevalence depends on who seeks help and how they are assessed, not just on how many people are unwell.
Screening tools built in one culture can miss cases in another — a classic imposed etic.
Treatment expectations differ: medication, talking therapy, family and community support, faith-based support.
Therapies like CBT can be adapted to fit local values rather than replaced — a strong evaluation point.
The same condition, a different shape
Across very different societies, researchers keep finding the same core: persistent low mood, loss of interest, disturbed sleep and appetite, low energy, thoughts of worthlessness. That consistency is a genuine argument for a shared human condition.
What shifts is which parts get pushed to the front. In many communities the first thing a patient reports is physical — a heavy chest, constant headaches, exhaustion that sleep does not fix. Emotional vocabulary comes later, if at all. Guilt is another good example: it sits near the centre of the Western picture of depression, and is far less prominent in descriptions from some other cultures, where the emphasis falls instead on shame, on letting the family down, or on a body that has stopped working properly.
Why the body, not the mood? Usually a mix of three things: physical complaints attract less stigma; local languages may frame suffering in bodily terms in the first place; and a doctor’s appointment is set up to ask about symptoms, not feelings. None of this means the sadness is absent.
Careful with wording here. “Some patients present somatically” is accurate. “People from that country do not feel sadness” is not, and it will cost you.
Why prevalence figures differ
A graph showing depression rates by country looks like a head count. It is not. It is a count of people who made it all the way through a filter — and every stage of that filter is shaped by culture.
Two countries with identical amounts of suffering can produce very different graphs if their filters differ.
So when a country shows a low reported rate, there are at least four live explanations before you reach “people there are less depressed”: stronger stigma keeping people away, fewer services to reach, a screening tool that asks the wrong questions, and different rules about what counts as a case.
Reading a prevalence graph in Paper 3
Describe the left panel to get started, then spend your answer on the right one.
🧩 A routine for any data source
Describe first. Name the highest and lowest values and the overall pattern, using the numbers given.
Ask what was measured. Diagnoses? Self-report? Hospital records? Each counts something different.
Ask who is missing. Anyone who did not come forward is invisible in the chart.
Check the tool. Same questionnaire everywhere? Translated? Standardised where?
Refuse causal claims. Correlational or cross-sectional data cannot tell you why.
Then conclude, in one careful sentence that matches how weak the evidence actually is.
Treatment is cultural too
The Western default is medication, talking therapy, or both. That is not the default everywhere. In many communities the first response to distress runs through family, elders, religious leaders or traditional healers, and being handed a prescription can feel like being told your relationships and your faith are irrelevant.
The interesting finding is that this is not an either-or. Therapies can be adapted rather than abandoned. CBT in particular travels reasonably well, because its focus on practical, here-and-now problem solving suits a lot of value systems — and its self-statements can be rewritten to draw on a client’s own faith, family and community rather than on individual self-belief. Adapted versions have been used successfully in a range of religious and cultural settings.
Two cautions to carry into an essay. First, adaptation costs money and trained people, and the places with the highest unmet need usually have the least of both. Second, no cultural group is uniform — a therapy tuned to a “typical” member of a community will still miss plenty of individuals inside it.
Worked examples
WORKED EXAMPLE
Practice source: a bar chart shows the percentage of adults diagnosed with depression in six countries during one year. Country A is highest at 11%; Country F is lowest at 3%. Explain one limitation linked to interpreting this data. [3 marks]
State the limitation
The chart records diagnoses, not the true amount of depression.
Explain why that matters
Reaching a diagnosis depends on stigma, on access to services and on which criteria were used, and these differ between the six countries.
Country F may simply have fewer clinicians, not fewer unwell peopleLink to interpretation
So the gap between 11% and 3% cannot safely be read as a difference in how common depression is.
The figures may lack validity as a measure of prevalence3 marks: one limitation, explained, tied to the data. Do not add a second.
WORKED EXAMPLE
Practice source: a clinic screens 300 adults twice — once with a mood-only questionnaire, once with a version that also asks about physical symptoms. The invented practice results below are for the same patients. Analyse the findings and state a conclusion linked to the claim that depression is less common in Group 2. [6 marks]
Group and tool
Screened positive
Group 1, mood-only questionnaire
24%
Group 1, questionnaire including physical symptoms
26%
Group 2, mood-only questionnaire
9%
Group 2, questionnaire including physical symptoms
23%
Describe the pattern
Group 1 barely moves (24% to 26%). Group 2 jumps from 9% to 23% once physical symptoms are included.
Interpret it
The tool, not the illness, explains most of the original gap. Group 2 appears to report distress somatically, so a mood-only measure missed most of those cases.
Evaluate
Quantitative and easy to compare, and the same patients were screened twice, which controls for participant differences. But screening positive is not a diagnosis, and we do not know how the questionnaires were translated.
Conclude against the claim
The evidence does not support the claim that depression is less common in Group 2.
The difference reflects the measure, not the disorderstate which condition performed differently and why — that is the analysis mark
💡 Exam tip
Learn the funnel. “Reported prevalence measures the filter as well as the illness” fits almost any data source in this topic.
Always describe the data before evaluating it. Skipping straight to criticism loses the easy marks.
Use exact figures from the source. Naming the highest and lowest values shows the examiner you read it.
Say somatic presentation when it applies — it is precise, and it shows HL-level vocabulary.
Adapted CBT is a strong, positive example. Essays that only criticise Western psychology look one-sided.
Never turn a correlation into a cause, however tempting the pattern looks.
⚠ Common mix-up
Low reported rates do not mean low suffering. They often mean a narrower funnel.
Somatic presentation is not a separate disorder. It is the same condition, described differently.
Do not generalise a whole country. Say “many patients in this sample”, not “people from X”.
Screening is not diagnosis. A positive screen means “look further”, nothing more.
Adapting therapy is not watering it down. Adapted versions can work as well or better.
A bigger sample does not fix a biased tool. Measure the wrong thing precisely and it is still wrong.
