In the social model, disability comes from society’s barriers rather than from the impairment itself. An impairment is a difference in function, but what disables someone are the ways environments, policies, and attitudes block participation—things like inaccessible buildings, lack of accommodations, rigid rules, and stigma. When those barriers are removed or reduced, people with impairments can participate more fully, showing that the disabling factor is the social context. So the society’s barriers are the primary source of disablement. This view contrasts with models that locate disability in the person’s impairment or attribute it to genetics, and it also moves beyond any notion of an equal mix by focusing on changing the environment to enable inclusion.

Disability is understood through where the problem is located: inside the person or in the surrounding world. The medical model treats disability as a problem in the individual—an impairment or pathology that needs diagnosis, treatment, or rehabilitation. The social model shifts the focus to society, arguing that barriers in the environment—architectural inaccessibility, lack of accommodations, and stigma—are what disable people with impairments. So the best statement captures this contrast: disability as a medical issue within the person, versus disability arising from societal barriers that exclude or hinder participation. The other options mix up this SAMPLEdistinction or misattribute where disability comes from: one implies the medical model centers on social barriers; another says disability under the social model comes from the impairment alone; and another claims disability is purely medical in both models.

Medicalization is the process by which everyday life or nonmedical problems are redefined and treated as medical issues, often under the authority of medical professionals and institutions. A classic historical example is childbirth, which shifted from mostly home-based, community-supported births to hospital births overseen by doctors, with anesthesia and other medical interventions becoming routine. This illustrates how social forces—professional power, technology, and institutions—shape what is considered a medical problem and how it should be treated. The other options don’t capture this idea: it isn’t about reducing medical roles, it isn’t about expanding home births, and it isn’t just a theoretical concept—there are clear real-world shifts like hospital birth that demonstrate medicalization.

Culture shapes how people understand illness, what treatments they prefer, how likely they are to follow prescribed care, and how they communicate with healthcare alike. This interconnected influence explains why the statement is best: illness interpretation varies across cultural backgrounds—some see illness as a spiritual imbalance, others as a biomedical issue—so patients may seek different explanations and pathways to care. Treatment preferences are also culturally guided, with some individuals favoring traditional remedies or complementary therapies in addition to or instead of biomedical treatments. Adherence is affected by beliefs about medications, dosing, side effects, and the involvement of family or community in decision-making. Communication styles are shaped by language, health literacy, and expectations about physician authority or patient autonomy, influencing how much information patients want and how they express concerns. Other options miss these nuances. Culture does not determine genetic susceptibility—the biology is not culture-based, even though culture can influence how genetics are understood or acted upon. And culture is not limited to non-biomedical care; it affects all aspects of care, including how patients perceive, accept, and respond to biomedical treatments, as well as how they interact with clinicians.
