Which concept outlines societal expectations regarding the behavior of those viewed as ill?

The concept that outlines societal expectations regarding the behavior of individuals viewed as ill is the sick role. This sociological concept, introduced by Talcott Parsons, delineates how society expects individuals who are diagnosed as sick to behave. The sick role encompasses two primary expectations: first, that the sick individual is not held responsible for their condition and thus is excused from normal social roles; second, that they are expected to seek medical help and strive to recover.

In this context, the sick role serves to not only define the responsibilities of the individual who is ill but also the societal reaction and support systems available for them. This highlights how illness is not just a personal experience but a social phenomenon influenced by norms and expectations. The other concepts, such as the disability role or patient role, do not specifically address these societal expectations regarding behavior in relation to illness, making the sick role the most accurate choice for this question.
