简要总结
This study examines how video information about mammography screening effect participants knowledge opinions and choice about screening.
详细描述
This study will be conducted as a single site parallel-arm, 1:1 randomized controlled trial (RCT) through a web-based quantitative survey uploaded in online forums. Participants will be randomized to either the intervention group (video information about mammography screening followed by a survey about mammography screening) or the control group (video information about energy systems followed by the same survey). The survey computer programme will randomly assign each respondent to either the intervention arm or the control arm in the beginning of the survey.
The allocation will be concealed from the researchers. The survey computer programme will deliver the intervention right after randomization. Participants will be aware of the allocation. However, they do not know about the study design. Data analysts will be kept blinded to the allocation.
Choice, knowledge and opinions related to mammography screening will be compared between the control group and the intervention group at one timepoint.

研究组 & 干预措施
Intervention group
Receives information about mammography screening through a video. The video was developed with the goal of informing about mammography screening in a societal perspective using best available evidence.
干预措施: Video information about mammography screening (Other)
Control group
Receives information about energy systems through a video. The video does not contain any information related to mammography screening.
干预措施: Video information about smart energy systems (Other)
结局指标
主要结局
Choice: proportion of participants in favor of mammography screening
时间窗: One month
The primary outcome in the study is choice. A possible effect of the intervention on choice will be examined by comparing the proportion of participants in favor of screening (on the individual level and societal level respectively) between the intervention arm and the control arm. One question addressing the societal choice and one question addressing the individual choice is included in our questionnaire.
次要结局
- Response duration: time(One month)
- Acceptability of the video: percentage of participants finding the video to be neutral, in favor of or against mammography screening.(One month)
