Impact of having a sibling with cancer or type I diabetes mellitus on psychopathology and self-conscious emotions in adolescents: a comparative study including controls.

Our results support prior studies in showing that CSs feel a greater level of guilt compared to adolescents without disease-stricken siblings, whereas, interestingly, CSs and DMSs were found to experience similar levels of guilt. Despite lack of significant increase in the CS and DMS groups, shame levels were positively correlated with depression and anxiety scores in all groups, but the lower correlation coefficients for the CS group indicate the presence of other factors influencing this relationship. We believe our results warrant the need for future studies evaluating the needs of the siblings of children with other chronic diseases, preferably with longitudinal follow-up to determine situations associated with need for psychosocial support.
