Boosting Blood Donations Through Facebook Engagement: Randomized Controlled Field Trial

Boosting Blood Donations Through Facebook Engagement: Randomized Controlled Field Trial

Because of the persuasive nature of the blood bank’s Facebook posts, we hypothesize that exposure to these posts will lead to the following: Hypothesis 4. New and current blood bank Facebook followers will be more likely to show up for their first blood donation (both the NDE and the regular first donation) compared with nonfollowers. Hypothesis 5. New and current blood bank Facebook followers will have donated more frequently compared with nonfollowers after 1 year.

Investigating Social Network Peer Effects on HIV Care Engagement Using a Fuzzy-Like Matching Approach: Cross-Sectional Secondary Analysis of the N2 Cohort Study

We attempted the download of phone contacts and Facebook friends one time, and if the download was not successful then we considered that participants’ data to be missing at random. We developed and tested a fuzzy matching algorithm (ie, deterministic linking algorithm) with a set of identifiers that provided a match result across confidant, sexual, phone contact, and Facebook networks.
