Social roles and long-term illness: is it time to rehabilitate convalescence?

The total extent of sickness in the population has increased while disease has decreased. Being sick is a role that offers the patient many advantages both directly, in terms of being absolved from undertaking many daily activities if necessary, and indirectly, through additional financial and other resources that may be offered. Because of these advantages, it is usual for any persistent sickness to be validated by health care professionals. Moreover sick people are expected to make every effort to leave the sick state, especially to make every effort using offered advice and resources such as rehabilitative treatments. However some people are sick longer than anticipated or apparently justified. The sick role developed based on assumptions that may no longer be valid, and the extended World Health Organization's International Classification of Functioning (WHO ICF) model of illness provides a new analysis of the problem, emphasizing that sometimes sickness is caused or perpetuated by factors other than disease. Among other factors, the lack of a way out of the sick role might be one reason for increasing sickness. Therefore re-establishing convalescence as a role might facilitate people in leaving the sick role, and rehabilitation should consider promoting convalescence.
