Purpose: To explore the experiences of adolescents with a sibling suffering from cancer from a salutogenic health promotion perspective.

Methods: Seven female siblings aged 13-17 years were interviewed. The interviews were transcribed and subjected to qualitative content analysis.

Results: The analysis findings adhered largely to one main theme: new challenges and needs in everyday life, consisting of the two domains cancer into life and helpful resources to cope. Categories related to the cancer into life domain were new routines and concerns, fear, loneliness, and growing up. Helpful resources to cope were categorized as support from others, understanding, faith and hope, and normal activities.

Conclusion: Prominent in the siblings' descriptions were the challenging changes in everyday life including difficult feelings such as loneliness, and a need for understanding. Social support appeared as a crucial salutogenic coping resource to achieve understanding, faith and hope, and identity-crucial spheres to achieve meaning in life. This study has demonstrated the significance of salutogenesis in a new setting, and the findings could be of relevance to teachers and health professionals consulting with the siblings of children with cancer. Further research should be conducted to pinpoint concrete health-promoting measures that might benefit this group.
