Discordance Between Sibling and Parent Reports of the Impact of Chronic Illness and Disability on Siblings

This study compared sibling and parent reports of sibling adjustment to chronic illness/developmental disability (CI/DD) in 51 siblings (ages 8 to 13). Discordance between sibling and parent reports on the Sibling Perception Questionnaire was common, with parents tending to report more sibling adjustment problems than did siblings. Siblings who reported more problems than parents tended to be younger and male. There was a trend for parents who reported more problems than siblings to also report greater negative impact of CI/DD on family social functioning than other parents. Findings highlight the importance of obtaining sibling self-reports in research and clinical settings.
