9.3 Health Beliefs, Explanatory Models & Health Literacy

Culture shapes how a patient understands illness itself — its cause, its meaning, and what counts as appropriate treatment. CCHI's cultural-responsiveness domain expects interpreters to recognize these health beliefs, render them faithfully, and support (without performing) the provider's work of negotiating across them.

Explanatory Models of Illness

Medical anthropologist Arthur Kleinman's concept of an explanatory model describes how a patient — or a provider — personally understands an illness episode: its cause, its timing, how it works, its expected course, and the treatment it calls for. Patients and biomedical providers frequently hold different explanatory models for the very same diagnosis, and an unrecognized gap between them is a major source of miscommunication, nonadherence, and patient dissatisfaction.

Kleinman's Explanatory-Model Questions

Providers, working through the interpreter, can elicit a patient's explanatory model with a short set of open questions:

1. What do you call this problem?
2. What do you think has caused it?
3. Why do you think it started when it did?
4. What does the sickness do to you — how does it work?
5. How severe is it, and will it have a short or long course?
6. What kind of treatment do you think you should receive?
7. What are the most important results you hope to get from treatment?
8. What are the chief problems the sickness has caused for you?

The interpreter's job is to render these questions and the patient's answers completely and faithfully, preserving nuance even when the answers describe non-biomedical causes — spiritual imbalance, punishment, disruption of "hot" and "cold" forces, or susto, among others.

The LEARN Model

A companion framework providers use to negotiate respectfully across explanatory-model differences is LEARN: Listen to the patient's perception of the problem, Explain the provider's own biomedical perception, Acknowledge and discuss the differences and similarities between the two, Recommend a treatment plan, Negotiate agreement. The interpreter supports every step by rendering both sides' explanatory models completely and neutrally — the interpreter does not do the listening, explaining, or negotiating; the provider and patient do that work through the interpreter.

Folk and Traditional Medicine

Patients often combine biomedical care with traditional or complementary practices:

• Curanderismo — Latin American folk healing
• Traditional Chinese medicine practices such as acupuncture, cupping, or coining
• Ayurveda — South Asian traditional medicine
• Hot–cold humoral theories of illness and treatment
• Use of a traditional healer alongside a physician
• Culture-bound idioms of distress such as susto ("soul fright"), mal de ojo ("evil eye"), or nervios

The interpreter's task is not to explain, validate, or dismiss these practices, but to interpret them accurately whenever the patient raises them, so the provider has complete information — for example, to screen for an herb–drug interaction. This is strictly a rendition function, never a clinical judgment the interpreter makes on the patient's behalf.

Dietary and Religious Practices

• Halal/kosher dietary law affecting hospital meal choices and medication ingredients such as gelatin capsules
• Religious fasting (for example, during Ramadan) affecting medication timing and glucose management
• Refusal of blood products, observed by many Jehovah's Witnesses, affecting consent for transfusion or certain procedures
• Modesty norms affecting who may be present in the room or who may touch the patient during an exam

Pain, Death, and Family Decision-Making

Expression of pain varies culturally, from stoic and minimizing to highly expressive; the interpreter renders the patient's actual words and tone without softening or amplifying them to match the interpreter's own expectations of "normal" pain behavior.

Around death and serious diagnoses, many cultures favor family-centered or collective decision-making over the U.S. biomedical default of individual patient autonomy, and some families ask that a terminal diagnosis not be disclosed directly to the patient. The interpreter's obligation does not change under this tension: interpret faithfully what each party says — including the family's request and the provider's response — without independently deciding, on the interpreter's own initiative, to withhold or soften information from the patient. That decision belongs to the provider, working within U.S. informed-consent and patient-rights law, not to the interpreter.

Health Literacy and Language Access

LEP patients frequently face compounded health-literacy barriers on top of the language barrier itself. The interpreter's role remains linguistic access, not patient education: render the provider's explanation at the same level of complexity used in the source language, and transparently flag if the patient's response suggests the explanation was not understood, so the provider can rephrase it — the interpreter does not simplify or re-teach the content unilaterally. Reliable language access, paired with attention to health beliefs and literacy, is directly linked to reduced disparities and better outcomes for LEP patients.

Health Disparities and the Case for Language Access

Documented research consistently links inadequate language access for LEP patients to worse health outcomes: longer hospital stays, higher rates of adverse events, lower rates of preventive screening, and lower satisfaction with care. Qualified, trained interpreters — as opposed to ad hoc use of family members or untrained bilingual staff — measurably narrow this gap. Attention to cultural health beliefs works alongside language access rather than substituting for it: a patient can receive a linguistically perfect interpretation and still leave confused or distrustful if the encounter never surfaces the explanatory-model gap driving the miscommunication in the first place.
