According to the functionalist perspective, health is vital to the stability of the society, and therefore sickness is a sanctioned form of deviance. Talcott Parsons (1951) was the first to discuss this in terms of the sick role: patterns of expectations that define appropriate behavior for the sick and for those who take care of them.
According to Parsons, the sick person has a specific role with both rights and responsibilities. To start with, the sick person has not chosen to be sick and should not be treated as responsible for her condition. The sick person also has the right of being exempt from normal social roles; they are not required to fulfill the obligation of a well person and can avoid her normal responsibilities without censure. However, this exemption is temporary and relative to the severity of the illness. The exemption also requires legitimation by a physician; that is, a physician must certify that the illness is genuine.
The responsibility of the sick person is twofold: to try to get well and to seek technically competent help from a physician. If the sick person stays ill longer than is appropriate (malingers), they may be stigmatized.
Parsons argues that since the sick are unable to fulfill their normal societal roles, their sickness weakens the society. Therefore, it is sometimes necessary for various forms of social control to bring the behavior of a sick person back in line with normal expectations. In this model of health, doctors serve as gatekeepers, deciding who is healthy and who is sick—a relationship in which the doctor has all the power. But is it appropriate to allow doctors so much power over deciding who is sick? And what about people who are sick, but are unwilling to leave their positions for any number of reasons (personal/social obligations, financial need, or lack of insurance, for instance).
