Final answer:
Talcott Parsons's sick role theory, which outlines the rights and obligations of the sick, does not work for all types of illness due to various social and personal factors that can affect one's ability to embody the sick role.
Step-by-step explanation:
The statement that Talcott Parsons's theory of the sick role works for all types of illness is false. Parsons's sick role model defines behavior expectations for the sick and their caretakers, where the sick are exempt from normal roles and have the right to be taken care of, given that they seek treatment and wish to get better. A physician must confirm the legitimacy of their illness. However, this model does not accommodate every type of illness or every individual's circumstances.
Factors like class, race, and gender, as well as personal and social obligations or financial constraints, can influence a person's ability to adopt the sick role completely. However, Parsons's theory has been criticized for its limited applicability to certain illnesses and cultural contexts. Some illnesses may not fit neatly into the sick role because of stigma, chronicity, or varying cultural beliefs about illness.
