Blood donors' physical characteristics are associated with pre- and post-donation symptoms - Donor InSight.

Background: Observational data suggest that some donors might benefit from donating while others may be harmed. The aim of this study was to investigate the prevalence and potential, routinely measured, determinants of pre- and post-donation symptoms.

Materials And Methods: In Donor InSight, questionnaire data from 23,064 whole blood donors (53% female) were linked to routinely measured data on donors' physical characteristics (haemoglobin, blood pressure, body mass index and estimated blood volume) from the Dutch donor database.

Return behavior of occasional and multigallon blood donors: the role of theory of planned behavior, self-identity, and organizational variables.

Background: For blood establishments it is important that blood donors return for a donation. Past research has stressed the importance of theory of planned behavior (TPB) on return behavior, but self-identity (SI) and organizational variables (OVs) might play a role as well. This study added SI and OVs to the TPB to identify the determinants for return behavior.

Characteristics of donors who do or do not return to give blood and barriers to their return.

Background: In the Netherlands about 50% of whole blood donors return to give blood after an invitation to donate. This study aimed to investigate the characteristics of donor return behaviour and to gain insight into the barriers to blood donation reported by the donors themselves.

Materials And Methods: A total of 4,901 whole blood donors were invited to donate in week 39 of 2009.

Does questionnaire distribution promote blood donation? An investigation of question-behavior effects.

Purpose: The purpose of this study is to assess the effectiveness of survey administration as a population-level intervention to increase blood donation.

Methods: Study 1 was a randomized controlled trial of new donors comparing 3,518 who received a questionnaire and 3,490 who did not. Study 2 compared matched, randomly selected samples of active donors; 5,789 received a questionnaire, while 6,000 did not.

The influence of adverse reactions, subjective distress, and anxiety on retention of first-time blood donors.

Background: This study investigated the effects of adverse events (i.e., needle reactions, fatigue, and vasovagal reactions) and feelings of distress and anxiety on retention of first-time blood donors.

Are lapsed donors willing to resume blood donation, and what determines their motivation to do so?

Background: This study investigated the possibility of rerecruiting lapsed blood donors. Reasons for donation cessation, motivation to restart donation, and modifiable components of donation motivation were examined. We distinguished between lapsed donors who had passively withdrawn by merely not responding to donation invitations and donors who had contacted the blood bank to actively withdraw.

Motivating blood donors to recruit new donors: experimental evaluation of an evidence-based behavior change intervention.

Objective: A sustainable, evidence-based intervention to motivate current blood donors to recruit new donors was evaluated using a quasi-experimental, in-service trial at three donation centers.

Design: Participating blood donors in three conditions (N = 734), received (1) an evidence-based leaflet designed to enhance recruitment motivation and five postcards facilitating recruitment and donor registration, (2) five postcards alone, or (3) no materials.

Main Outcome Measures: Self-reported donor recruitment by donors was measured at 1-week and 6-week follow-up.
