Psychosocial characteristics of blood donors influence their voluntary nonmedical lapse.

Certain psychosocial characteristics increase risks of voluntary lapse. Especially donors with higher donation anxiety had increased lapsing risks. They might benefit from extra attention during donation. Donors with more information need or wish about procedure and patients were less likely to lapse, indicating that binding with the blood bank might prevent lapse. Generally, this study showed that donor lapse and donor return are determined by different psychosocial factors not just the reverse of each other.
