2026년 5월 6일 업데이트: UNC Lineberger Comprehensive Cancer Center
The main purpose of this trial was to evaluate the impact of user interface designs on intervening with cancer misinformation on social media.
The investigators conducted a randomized clinical trial with a sample of 294 US adults (ages 18-65) who previously had a cancer diagnosis or were a cancer caregiver.
This registration record only covers the 5 timepoint trial under the same IRB number.
연구 개요
상세 설명
This 5 timepoint trial aimed to determine whether user interface designs encouraged intervening and reduced sharing of cancer misinformation on social media. The investigators enrolled 294 adults, ages 18-65, who had received a cancer diagnosis or were a cancer caregiver. Participants completed 5 online surveys, space approximately 2 business days apart. In the first survey, participant were randomized to 1 of 3 trial arms, described below. During each online survey, participants interacted with a simulated social media platform, branded as Invibe. Participants had passive exposure to stimuli cancer misinformation posts and cancer support posts in social media feeds. Participants also had forced exposure to stimuli posts in the online survey after interacting with Invibe. The investigators recorded social media behavior on Invibe and assessed self-reported measures in the online survey.
This study was preregister on AsPredicted.com on March 24, 2025, prior to data collection and data analysis (https://aspredicted.org/te3su2.pdf).
