TriangleNCT03856437 · STUDY IN CONTEXT
A Message Framing Intervention for Increasing Parental Acceptance of Human Papillomavirus Vaccination
Draft scope assessment: narrower. Linked by condition-string match at the cancer-entity level. The study's eligibility - stage, biomarker, treatment line and prior therapy - has not been reconciled against this page's definition, so its population is narrower than this page in ways not yet recorded. Found by searching ClinicalTrials.gov for this cancer type, restricted to studies that have posted results to the registry. No FDA notice, FDA label or NCI summary held by this site cites this study. Because the search asked for posted results, studies without posted results were never looked for, so their absence from this page means nothing.

Linked outcomes
Attitudes toward HPV vaccination for children Scale range: 1-7 (higher score indicates more positive attitude) Subscales were averaged.
Intention to have children vaccinated against HPV free of cost Scale range: 1-6 (higher score indicates stronger intention) Subscales were averaged.
Intention to have children vaccinated against HPV free with cost Scale range: 1-6 (higher score indicates stronger intention) Subscales were averaged.
