The forgotten siblings: can two surveys give voice to children living beside a brother or sister with cancer?
NCT ID NCT06854822
First seen Sep 21, 2026 · Last updated Sep 21, 2026
Summary
Brothers and sisters of children with cancer often face loneliness, fear, and grief, yet Swedish clinics have no standard way to measure what they need. This study translates two questionnaires into Swedish: the Sibling Cancer Needs Instrument, which asks about information, support, and family understanding, and the PG-12, which screens for prolonged grief during a sibling's illness. Researchers will adapt the wording with help from experts and about 10 siblings, then ask roughly 200 siblings aged 12 to 24 to complete a web survey. The goal is to check whether the Swedish versions are reliable and valid enough for clinics to use.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- two questionnaires: the Sibling Cancer Needs Instrument and the Prolonged Grief Disorder PG-12 scale, translated into Swedish
- What this could lead to
- If the Swedish versions prove reliable, clinics and schools could use them to spot siblings who need support and to identify those at risk of prolonged grief before a loss occurs.
- What could go wrong
- This is a questionnaire study, not a treatment, so it cannot show that any support helps. A translated survey may not work the same way in Swedish as in its original language, and 200 siblings is a modest sample for testing a 45-item tool.
