This study will determine if attitudes can be enhanced and adherence to treatment regimen improved in Cystic Fibrosis (CF) adolescent patients by using a simulation game "My Life with CF" . The target population is CF patients ages 12-21 years. Attitudes will be assessed utilizing four attitude scales in CF adolescents pre and post experiencing the simulation game. In the simulation game, patients make life decisions, including CF therapy decisions, using a fictional character diagnosed with CF. The game has been designed to help players understand the long-term effects of health care choices. Data from this pilot study will assess changes in attitudes and reported changes in adherence.
