Facial Action Unit Data for the FAINT project

The study took place at four blood collection centres (BCC Leiden, ‘s-Hertogenbosch, Zwolle, and Utrecht). We invited all blood donors who fit into the following three groups to participate: (1) the control group; with between 5 to 10 previous donations, and no previous experience of vasovagal reactions, (2) the sensitive group; with 5 to 10 previous donations but with the experience of a VVR at the previous donation, and (3) new donor group; first-time donors.

During data collection, the donors had their regular blood donation procedure consisting of several phases: registration, health check at the donor physician, blood donation, and cafeteria visit. We used a standard RGB video camera to record the face of each blood donor before the blood donation procedure (stage 1: after they completed the questionnaire, stage 2: after registration). At the same time, we asked each blood donor to self-report vasovagal reactions (VVR) experienced at each disting phase of the blood donation.
