Eligible studies included those examining siblings of children with cancer aged 21 years old or younger and on active treatment and reported on factors associated with sibling experiences of distress. Identified factors were categorized in accordance with the 4Ps of case formulation (predisposing, precipitating, perpetuating, and protective factors).

Predisposing, precipitating, and perpetuating factors increased sibling distress, while protective factors reduced sibling distress.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>We identified factors associated with distress in siblings of children with cancer.
