Acculturation and Its Effect on Mental Health
Moving to a new country is not just a change of address. You have to work out how to greet people, what counts as rude, how loud to talk, what to eat and when. Doing all of that while missing home is hard work — and psychologists have a name for the strain it causes.
📚 What you need to know
Acculturation is what happens to a person psychologically when they move into a culture that is not the one they grew up in.
It is the opposite of enculturation, which is learning your own culture as a child.
Acculturation is two-way. The new culture changes the migrant, and migrants change the new culture too.
Berry described four strategies: integration, assimilation, separation and marginalisation.
Integration — keeping your own culture while joining the new one — is linked to the best mental health.
When the strategy does not work, or when the host culture pushes back, the result is acculturative stress.
The study you need is Inman et al. (2007), on first-generation Indian Hindu parents in the USA.
What acculturation actually means
You learn your first culture without noticing. Nobody sat you down and taught you how close to stand to a stranger or how to answer a teacher — you picked it up. That is enculturation.
Acculturation is the same learning, but done as an adult, on purpose, and usually in a hurry. A person moves country and has to rebuild a whole set of habits that everyone around them already has. Some people move by choice, for work or study. Others are pushed out by war, hunger or money. That difference matters, because a person who chose to move usually feels far more in control than a person who had no choice.
It goes both ways. A migrant learns the new language and customs, but they also bring food, music, words, religion and art that the host culture takes on. This is why psychologists call acculturation bi-directional rather than one-way absorption.
Berry’s four strategies
Berry noticed that a person facing a new culture is really answering two questions at the same time. Do I hold on to my own culture? And do I take part in the new one? Answer yes or no to each, and you get four possible positions.
The strategy is not always freely chosen. A host culture that demands assimilation can push someone into a box they never wanted.
Learn the grid, not just the four words. If you can rebuild the two questions in the margin of your exam paper, you can work out all four strategies from scratch even if the names slip your mind.
Where acculturative stress comes from
Acculturative stress is the psychological strain of the whole process. It is not one big event; it is a slow build-up of small frictions. Three things tend to feed it.
A clash of norms. What is polite at home may be rude here. The migrant is constantly guessing, and constantly getting it slightly wrong.
Pressure to assimilate. The host culture may expect people to drop their old ways completely. If the migrant does not agree with that, every day involves a small argument with the place they live in.
No room to practise your own culture. If there is no temple, no shop selling the right food, no one who speaks your language, then keeping your culture takes effort that other people never have to make.
Stress that never lets up is a health problem, not just a mood. Long-running acculturative stress has been linked to depression, anxiety, PTSD and suicidal thoughts. This is why the topic matters far beyond the exam.
Why integration usually wins. Someone who integrates has two sources of support instead of one. They still have their family, faith and community from home, and they have colleagues and friends in the new country. Marginalisation is the opposite — it removes both at once, which is exactly why it is the riskiest position to end up in.
Key study: Inman et al. (2007)
This is a qualitative study, so there are no percentages to learn. What examiners want is that you can describe the method and say what it shows.
Part of the study
What happened
Aim
To look at ethnic identity and acculturative stress in first-generation Indian Hindu parents who had settled in the USA.
Participants
16 parents (8 mothers, 8 fathers) who had moved to America in the late 1960s and early 1970s. All were over 20 when they emigrated and all spoke fluent English. They were found using purposive and snowball sampling.
Procedure
Before the interview each parent placed themselves on a scale running from ‘very Indian’ through ‘bicultural’ to ‘very American’. Semi-structured interviews then asked them to explain that choice. The transcripts were analysed for themes.
Results
Most described themselves as ‘very Indian’ or ‘bicultural’. Cultural celebrations, traditional values, strong family ties and social support all helped them hold on to their identity. Difficulties included inflexible work schedules, few Indian cultural centres, and worry that their children would drift away from the culture.
Conclusion
First-generation parents can acculturate successfully, but success is not the same as ease. Where there was little chance to practise their own culture, stress followed.
Notice how neatly this study lines up with Berry. The parents who called themselves ‘bicultural’ are describing integration, and they were the ones coping best. Making that link in an essay turns description into evaluation.
Evaluating the research
What is strong about it
The interviews were semi-structured, so parents could raise things the researchers had not thought to ask about. That is how the worry about intermarriage and generational distance came out at all.
The pre-interview self-rating was cross-checked against what people said in the interview, and the analysis was confirmed by an external auditor. That improves credibility.
The topic has obvious real-world value given how many people are forced to move country.
What is weaker about it
16 people is a very small sample from one religious and national background, so you cannot generalise to migrants everywhere.
Couples were interviewed who lived together. They could easily have discussed their answers beforehand, which would affect the credibility of what they said.
Snowball sampling finds people through people, so participants are likely to share a social circle and therefore share attitudes.
Link to concepts
Measurement: qualitative interviews are often treated as second-class next to experiments. That is short-sighted here — you cannot capture what it feels like to lose a culture with a rating scale.
Responsibility: research on migrants is socially sensitive. Findings can be twisted by the media into hostile stories about immigration, so researchers have a duty of care in how they publish.
EXAM PRACTICE
Explain one effect of acculturation on mental health, with reference to one study. [9]
A 9-mark question wants a clear effect, one study described in reasonable detail, and a link between the two. Here is the shape of a strong answer.
Step 1: name the effect clearly
Acculturative stress — the strain of adapting to a new culture — can damage mental health, and how much depends on the strategy used.
Step 2: explain the mechanism
Integration keeps two support networks. Marginalisation removes both, so the person has no group to fall back on.
Step 3: bring in the study
Inman et al. (2007): 16 first-generation Indian Hindu parents in the USA, semi-structured interviews after a self-rating of cultural identity.
Step 4: use the findings, do not just list them
Most called themselves ‘very Indian’ or ‘bicultural’, and cultural celebrations plus family ties protected them. Where opportunity to practise the culture was missing, stress rose.
Step 5: one line of evaluation
Only 16 participants from one background, so this cannot be generalised to all migrants.
Effect + study + link + limitation = full marksThe marks are in the link, not the list. Say why the study shows the effect.
💡 Exam tip
Say acculturative stress, not ‘culture shock’. The examiner is looking for the technical term.
Always name the strategy you are discussing. ‘Integration’ earns credit; ‘fitting in’ does not.
For a 22-mark essay, spend roughly a third on the study and two thirds on explanation and evaluation.
Qualitative studies have no numbers. Do not invent statistics for Inman — describe themes instead.
If you also study Smith & Bond or Hofstede, you can use collectivism and individualism to explain why the norms clash. That depth is worth marks.
⚠ Common mix-up
Acculturation vs enculturation. Enculturation is learning your first culture as a child. Acculturation is adapting to a second one.
Assimilation vs integration. Assimilation means giving the old culture up. Integration means keeping both. They are not synonyms.
Assuming the migrant chooses. A host culture that refuses to accept difference can force separation or marginalisation on someone.
Treating acculturation as always negative. It can be a positive, enriching experience — the stress is a risk, not a certainty.
Saying the sample was ‘random’. Inman used purposive and snowball sampling, which is the opposite of random.
Up next: Commitment as a Compliance Technique — how getting someone to say yes to something tiny makes them far more likely to say yes to something big.
