How Cultures Differ in Defining Mental Illness
Diagnosis feels like a medical fact: you either have the illness or you do not. But a diagnosis is a judgement made by a person, using a checklist written by other people, in a particular culture. Change any part of that and the answer can change too.
📚 What you need to know
Bias is when personal attitudes or stereotypes affect what should be a neutral, objective process.
Clinical bias is when a clinician’s prejudice, discrimination or political views shape the diagnosis.
Bias can be conscious (the clinician knows) or unconscious (they do not).
Culture bias is assuming one culture defines “normal”, so others look inferior or abnormal.
An etic approach assumes behaviour is universal; an emic approach understands it from inside the culture.
Cultural relativism means behaviour can only be judged against the norms of its own culture.
Jenkins-Hall & Sacco (1991) is your key study, and the pattern in its results matters more than the headline.
Why diagnosis is not neutral
Two things have to happen for a diagnosis. Someone has to show symptoms, and someone else has to notice and interpret them. The second step is where bias gets in.
🧩 What goes wrong when bias enters the room
Patients feel dismissed or unheard, and start doubting whether their symptoms are even serious.
Patients receive the wrong treatment, or no treatment at all, which can make the condition worse.
At a wider level, prevalence rates get recorded incorrectly, which feeds discrimination and prejudice back into the system.
Where does the bias come from? Partly from cultural stereotypes — assumptions about the intelligence, ability or behaviour of certain groups. And partly from the biomedical model itself, which grew up in Western, individualistic cultures and can quietly carry gender and cultural bias into diagnosis.
Etic and emic
These two words are worth memorising precisely, because examiners use them and students confuse them constantly.
The difference in one line
Etic = judging from outside with one shared standard • Emic = understanding from inside that culture
Culture bias is more likely to affect collectivist cultures, which may rely on culture-bound concepts and traditional treatments rather than the biomedical model.
Two real examples
African-Caribbean people in the UK and USA are diagnosed with schizophrenia more often than Caucasian people.
Puerto Rican patients may show strong physical stress responses such as fainting or heart palpitations. US clinicians have often misdiagnosed these as psychotic episodes.
The second example is the cleaner one for an essay. In that culture, distress is expressed through the body. A clinician trained to expect distress to be expressed in words about feelings sees something unfamiliar and reaches for the most serious label available. Nothing about the patient was psychotic. The mismatch was between the expression and the expectation.
🔬 Jenkins-Hall & Sacco (1991)
A controlled test of bias in diagnosis
AIM
To investigate cultural bias in diagnosing depression.
PARTICIPANTS
62 White US psychotherapists (39 female, 23 male; average age 36). All held master’s degrees and had at least three years of practice.
PROCEDURE
Each therapist watched a 3-minute video of a staged consultation. The independent variable had four conditions: a White female “depressed” client, a Black female “depressed” client, a White female “nondepressed” client, and a Black female “nondepressed” client. It was an independent measures design, so each therapist saw only one condition. Scripts were based on standardised depression inventories covering low mood, loss of interest and poor sleep. Therapists then rated the client on depressive symptoms, social skills and psychological state.
RESULTS
All depressed clients were correctly diagnosed. Non-depressed White and Black clients were rated similarly. But Black depressed clients were rated lower for social skills and likeability and more negatively overall than White depressed clients. Being both Black and depressed produced the most negative ratings of all.
CONCLUSION
The therapists showed racial bias, and that bias could lead to adverse or harmful treatment outcomes.
Look carefully at the pattern, because it is more interesting than “therapists were biased”. The diagnosis was accurate every time, and the non-depressed clients were rated the same regardless of race. Bias only appeared in the judgements around the diagnosis, and only for the depressed Black client. That combination is called an interaction effect, and pointing it out will separate you from every other candidate.
Why that matters practically
If bias sits in the ratings of social skills and likeability rather than the diagnosis itself, it will not show up in any diagnostic statistic. It will show up in how the person is treated afterwards: how much time they get, how their progress is judged, how seriously their setbacks are taken. That is a far harder problem to audit.
Evaluating this research
Strengths
Limitations
The findings support previous research, reinforcing the validity of cultural differences in mental health diagnosis.
Some participants may have realised the consultations were fake, giving rise to demand characteristics.
Standardised rating scales were used, an example of data triangulation that raises validity and reliability.
A 3-minute video is nothing like a real course of therapy, so ecological validity is low.
Controlling everything except the client’s race isolates the variable cleanly.
Research on cultural differences is socially sensitive and risks being misused to reinforce stereotypes about minority groups.
Independent measures prevented therapists comparing conditions and guessing the aim.
All therapists were White and US-based, so the findings cannot be generalised to other systems.
Linking to the concepts
Bias: it operates at a personal level (one wrong diagnosis and treatment) and a global level (misreported prevalence rates that keep prejudice going). That in turn can worsen mental health in specific cultural groups, because people are not being properly seen or heard.
Responsibility: clinicians have to treat each patient as an individual and honour their cultural heritage as part of the diagnostic process. There is no single universal approach, and only an emic one really serves the patient.
EXAM ANSWER
Discuss the role of culture in the diagnosis of one disorder. [22 marks]
Define the problem precisely
Culture bias is assuming one culture defines normality, so behaviour outside it looks abnormal. It enters diagnosis through an etic approach.
Give a concrete case
Puerto Rican patients expressing distress physically have been misread as psychotic by US clinicians.
Evidence with the detail that counts
Jenkins-Hall & Sacco: diagnosis was accurate, but Black depressed clients were rated lower on social skills and likeability than White depressed clients.
Evaluate the method honestly
A staged 3-minute video limits ecological validity, and demand characteristics are possible.
Conclude: an emic approach and researcher reflexivity are the fixnaming a solution, not just a problem, is what “discuss” is really asking for
💡 Exam tips
Etic and emic are cheap marks. Define both in one sentence each and use them accurately throughout.
Use cultural relativism when arguing that “abnormal” only makes sense against local norms.
Say whether bias is conscious or unconscious. Unconscious bias is harder to fix, which is a stronger argument.
The interaction effect in Jenkins-Hall & Sacco is a top-band detail. Learn it as “bias appeared only in the depressed condition”.
Socially sensitive research is a reusable evaluation point for any study on race or culture.
This page pairs with the previous one: culture affects both the rate and the recognition of disorder.
⚠ Common mix-ups
Swapping etic and emic. Emic = inside. That one letter is your memory hook.
Saying the therapists misdiagnosed people. They did not. The bias was in the surrounding ratings.
Confusing culture bias with cultural relativism. One is the error, the other is the corrective principle.
Treating unconscious bias as an excuse. Unaware still causes harm; it just needs different solutions.
Forgetting the design. Independent measures, four conditions, one video each. Method detail earns marks.
Assuming Western diagnosis is the neutral baseline. The biomedical model is itself a cultural product.
