A demonstrative case of an HIV-positive adolescent girl is presented in order to illustrate the stages of adaptation that HIV-positive youth undergo. Also discussed is the process by which this individual changes her behavior and the integral role and contributions the service provider can make in the behavior-change process for HIV-positive youth. Finally, this case illustrates some of the unique issues encountered by HIV-positive young women and how those issues can be incorporated into a comprehensive, coordinated, and continuous system of care.
