Background: In Norway each year 130-150 children are born with heart disease that requires lifelong medical follow-up. Children with heart defects have reduced motor skills and reduced physical capacity compared with healthy peers. Increased knowledge in the children themselves and the general public, along with psychosocial interventions improve the child's ability to cope with the consequences of their disease. Descriptions of the experiences that Norwegian children with heart disease and their parents have about participation in rehabilitation programs is limited. Geilomo children's hospital has 75 years experience in rehabilitation of children with chronic illness, and started in 2005 to welcome children with heart disease. At present there is no rehabilitation institutions in Norway that has a special group programs for children with heart disease. Geilomo want to establish such a group for children aged 6-7 years and 11-12 years.

Main objective: The investigators will use of methods to learn more about the following:

Study 1: The purpose is to generate knowledge about how children with heart disease and their relatives experience participation in a rehabilitation program at Geilomo children's hospital.

Study 2: The purpose is to help a) to give the children an increased level of activity in the home environment.

Work schedule: The project will have a duration of 3 years. The project will seek approval of the Regional Committee for Medical Research Ethics in May 2012. Interview Guide, information sheet and consent form has been prepared. Data collection for the study 2AB can start in March 2013. The first interviews will be conducted after 3 months, in June 2013. Data collection is expected to be completed in December 2013. The analysis will take place in parallel with the interview work. In 2014 and 2015 completed the writing of articles (3 pieces) and publication of results.

Method: In order to shed light on the problem in study 1, the investigators will use semi-structured interview. 16 children and 16 parents to be interviewed after 3 months.
