Abstract: Fear is a recognized predictor of vasovagal reactions (VVRs) in blood donors. However, less is known about the role of other emotions, including positive emotions, that donors might experience. The aim of this study was to identify the emotions experienced in center that predict onsite VVRs, and to determine at what point during the donation appointment, the experience of these emotions is most influential. A s le of 442 first‐time whole‐blood donors (57.7% female mean ± SD age 30.7 ± 11.7 years) completed a survey in the waiting area and before venepuncture in the donation chair to assess their current emotional experience. The survey data were matched with routinely‐collected demographic, donation, and donor adverse event information. A generalized estimating equations model was used to identify emotions associated with the occurrence of a VVR. A total of 56 (12.7%) participants experienced a VVR. The occurrence of a VVR was significantly associated with lower love/closeness/trust (OR: 0.53, 95%CI: 0.34–0.82) and higher scared/fearful/afraid (OR: 1.96, 95%CI: 1.18–3.25) states . Significant interaction effects suggested that the effect of scared/fearful/afraid decreased while stressed/nervous/overwhelmed increased from the waiting area to before venepuncture on the likelihood of a VVR. To effectively reduce donor VVR risk, blood collection agencies need to address a broader range of emotions at different points during the donation process.

Abstract: The red-attraction effect refers to the finding that the color red enhances attractiveness ratings of targets, and is most robustly observed when males rate females. Three previously unexplored aspects of color-attraction effects were tested in a single experiment with a large s le size (N = 778). The effect of exposure to a color and the impact of pairing a color with a target were disentangled using a novel design. Moreover, we tested the proposition that color exerts its effects outside of awareness by examining the association of conscious awareness of color-target pairing with the red-attraction effect. Both prior exposure to red and pairing of red with a target influenced attractiveness ratings, but not always in the direction of increased attractiveness. Results also varied as a function of target and participant sex. However, when conscious awareness of target-color pairing was higher, results converged with the typically-observed red-attraction effect among males rating females.

Abstract: Donors are the key to the core business of Blood Collection Agencies (BCAs). However, historically, they have not been a focus of research undertaken by these organizations. This model is now changing, with significant donor research groups established in a number of countries, including Australia. Donor research in the Australian Red Cross Blood Service (Blood Service) is concentrated in the Donor and Community Research (DCR) team. Cognizant of the complex and ever-changing landscape with regard to optimal donor management, the DCR team collaborates with academics located at universities around Australia to coordinate a broad program of research that addresses both short- and-long term challenges to the blood supply. This type of collaboration is not, however, without challenges. Two major collaborative programs of the Blood Service's research, focusing on i) the recruitment and retention of plasmapheresis donors and ii) the role of the emotion pride in donor motivation and return, are showcased to elucidate how the challenges of conducting collaborative BCA research can be met. In so doing, these and the other research programs described herein demonstrate how the Blood Service supports and contributes to research that not only revises operational procedures but also contributes to advances in basic science.

Abstract: The aim of this research was to test a model integrating self-determination theory (SDT) and the theory of planned behaviour (TPB) to predict intention to donate blood. Social science research suggests that motivational orientations outlined by SDT can be usefully integrated with constructs from the TPB to collectively predict intention and behaviour. Such analysis has not yet been undertaken in the context of blood donation. A total of 458 currently eligible donors completed measures of blood donor motivations, attitudes, subjective norms, perceived behavioural control (PBC) and intention. Path analyses modelled the direct and indirect effects (via TPB constructs) of motivational orientations on intention. SDT motivational orientations explained an additional 14% of the variance in blood donation intention, compared to a TPB-only model. Amotivation had a negative direct effect on intention external regulation had no overall effect on intention introjected regulation had positive direct and indirect effects on intention and autonomous motivation predicted intention both directly as well as via attitudes, subjective norms and PBC. This research provides the first evidence that integrating SDT and the TPB is a useful approach in donor research, particularly for specifying plausible pathways through which motivational orientations impact intention to donate blood.

Abstract: b i Background: /i /b Research on the recruitment and retention of blood donors has typically drawn on a homogeneous set of descriptive theories, viewing the decision to become and remain a donor as the outcome of affectively cold, planned, and rational decision-making by the in idual. While this approach provides insight into how our donors think about blood donation, it is limited and has not translated into a suite of effective interventions. In this review, we set out to explore how a broader consideration of the influences on donor decision-making, in terms of affect, memory, and the context in which donation takes place, may yield benefit in the way we approach donor recruitment and retention. b i Summary: /i /b Drawing on emerging research, we argue for the importance of considering the implications of both the positive and the negative emotions that donors experience and we argue for the importance of directly targeting affect in interventions to recruit nondonors. Next, we focus on the reconstructed nature of memory and the factors that influence what we remember about an event. We discuss how these processes may impact the retention of donors and the potential to intervene to enhance donors’ recollections of their experiences. Finally, we discuss how our focus on the in idual has led us to neglect the influence of the context in which donation takes place on donor behavior. We argue that the amassing of comprehensive large data sets detailing both the characteristics of the in iduals and the context of their giving will ultimately allow for the more effective deployment of resources to improve recruitment and retention. b i Key Messages: /i /b In suggesting these directions for future research, our want is to move beyond the ways in which we have traditionally described blood donation behavior with the aim of improving our theorizing about donors while improving the translational value of our research.
