Sociological Theories Applied to Medicine

The MCAT specifically tests how sociological theories map onto healthcare. Here’s how each lens analyzes the same set of health phenomena.

Functionalism in Medicine

Functionalism asks: what purpose does the medical institution serve for society?

• Treating illness and restoring productive citizens to the economy.
• Controlling who can take the sick role (physicians as gatekeepers - Parsons).
• Certifying competence (medical licensing).
• Managing death and dying (hospitals as repositories for the ill and dying).
• Public health functions (vaccination, sanitation, health education).

Dysfunctions: over-reliance on medicalized solutions when non-medical interventions might work; iatrogenic harm (illness caused by medical treatment); healthcare costs that strain other institutions.

Conflict Theory in Medicine

Conflict theory asks: who holds power in healthcare, and at whose expense?

• Physicians historically held substantial power and prestige; the structure of medical training produces a class hierarchy with attendings > residents > interns > students.
• Pharmaceutical companies shape research priorities, drug pricing, and access.
• Insurance companies control access to care.
• Low-income and marginalized patients have worse access and outcomes - a structural, not individual, failure.
• Global health inequality - some countries have near-universal healthcare, others minimal; patent systems concentrate new treatments in wealthy markets.

Conflict theorists also examine how medical authority can be used to enforce social norms (diagnosing deviance, controlling reproduction, treating political dissidents as mentally ill).

Symbolic Interactionism in Medicine

Symbolic interactionism asks: how is illness experienced and constructed in interaction?

• Identity as “patient” vs. “person.” Hospitals tend to strip patients of their normal identities (wearing gowns, being called by bed number) and reconstruct them as diagnoses.
• Labeling. Receiving a diagnosis becomes part of identity - “I am a diabetic” vs. “I have diabetes.” Labels carry weight.
• Stigma - mental illness, HIV, obesity all carry stigma that reshapes social interactions and self-concept.
• Doctor-patient communication. How language (jargon, euphemism, empathy, coldness) shapes the clinical encounter.
• Front-stage/back-stage in medical settings. Doctors perform confidence in front of patients while expressing uncertainty in back-stage conversations with colleagues.

Feminist Theory in Medicine

Feminist theory examines how gender shapes medical institutions, research, and care.

• Historical male dominance in medicine (and continuing disparities in specialization, pay, and leadership).
• Medical research bias. Until the 1990s, clinical trials often excluded women. Drug dosing and symptom profiles developed on male subjects can be wrong for women (heart attacks often present differently in women; dosages of many drugs are calibrated to male physiology).
• Medicalization of women’s bodies. Childbirth, menopause, menstruation, and fertility have been heavily medicalized - sometimes reducing patient autonomy.
• Pain dismissal. Evidence that women’s pain is systematically undertreated compared to men’s.
• Intersectional analysis. Women of color experience worse healthcare outcomes than white women, reflecting intersecting oppressions.

Social Constructionism in Medicine

Social constructionism asks: what counts as a disease, and how does that change?

• Diagnostic categories evolve. Hysteria disappeared from the DSM. Homosexuality was a mental illness until 1973. Attention deficit and autism have expanded their diagnostic boundaries.
• Culture-bound syndromes - some illnesses appear only in specific cultures (susto in Latin America, hikikomori in Japan).
• Contested diagnoses - fibromyalgia, chronic fatigue syndrome, long COVID have been debated as real/constructed.
• Aging. Is aging a disease? Growing debate; longevity medicine increasingly frames it so.

Constructionism doesn’t deny that patients suffer. It asks how suffering gets categorized, named, and treated - and how those categories shape what gets researched, funded, and legitimated.

Rational Choice in Medicine

Rational choice (and exchange theory) examine how patients and providers make decisions.

• Healthcare decisions as cost-benefit calculations (insurance choice, treatment options, seeking a second opinion).
• Doctor shopping - patients “shop” for physicians who match their preferences.
• Shared decision-making - contemporary medicine increasingly treats the physician-patient relationship as a negotiated exchange.

Real patients often deviate from rational choice predictions (Chapter 4’s heuristics and biases apply just as much in medicine - framing effects, availability heuristic, anchoring all shape medical decisions).
