Effect of a Web Page Based on a Motivational Video for Voluntary Blood Donation

Voluntary blood donation is currently a key issue in many countries, as the shortage of voluntary donors results in a deficit in the supplies of the Blood Banks of the hospitals. One factor for which there is a low number of voluntary donors is the limited dissemination of information that is given to the population regarding the facilities and benefits of blood donation. Objective: To evaluate the effect of a web page containing a motivational video and an informative text to promote the voluntary donation of blood disseminated through the use of social networks such as Facebook and WhatsApp. Design and Participants: Online randomized controlled trial for a group of 102 university students. Intervention: One group exposed to the intervention with video and the other control group exposed to informative text.
