Abstract
Objective To investigate whether adolescent siblings of childhood cancer survivors experience posttraumatic stress (PTS). Methods Participants included 78 adolescent siblings of adolescent cancer survivors who completed self-report measures of anxiety, PTS, and perceptions of the cancer experience. Results Nearly half (49%) of our sample reported mild PTS and 32% indicated moderate to severe levels. One fourth of siblings thought their brother/sister would die during treatment; over half found the cancer experience scary and difficult. These perceptions were related to PTS. Siblings reported more PTS symptoms than a reference group of nonaffected teens but had similar levels of general anxiety. Conclusions Levels of PTS are elevated for siblings of childhood cancer survivors. Thus, PTS may be a useful model for understanding siblings' long-term reactions to cancer. Future research and clinical efforts should consider the needs of siblings of childhood cancer survivors in a family context.
