Parental perceptions of risk and protective factors associated with the adaptation of siblings of children with cystic fibrosis.

When a child is diagnosed with a chronic, life-threatening illness, there is a significant impact on the healthy siblings. Few studies have addressed the adaptation of well siblings in diagnoses other than cancer. The purpose of this descriptive correlational study was to examine the relationships between the risk and protective factors that affect the psychological adaptation of healthy siblings of a child with cystic fibrosis. Findings from this study suggest family environment, especially parental stress and perceived social support, may affect the adaptation of the well sibling. Adolescent well siblings were more at risk for environmental influences than their younger counterparts.
