Article
Background Genomic testing is already used by blood collection agencies (BCAs) to identify rare blood types and ensure the best possible matching of blood. With ongoing technological developments broader applications, such as identification of genetic markers relevant to blood donor health, will become feasible. However, the perspectives of blood d...
Article
Background: 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 do...
Article
Background: Early in the COVID-19 pandemic, Australian donors aged 70 and over were advised to temporarily stop donating. The aim of this research was to understand the factors associated with some of these donors continuing to donate despite the advice, and whether adherence to the advice had negative implications for donor retention. Study desi...
Article
Full-text available
Nonprofits address some of the world's most pressing problems, and many rely on donations to fund their essential work. Nonprofit marketers are, therefore, tasked with promoting charitable giving. Research on giving has largely focused on identifying the characteristics that make people generous but has generated inconsistent findings, suggesting i...
Article
Rape victim testimony may seem incongruent with the ‘real rape’ stereotype and appear more consistent with typical consensual sex. This research investigated whether having victims describe stereotype-consistent events early in their testimony guides jurors to construct narratives of the evidence that are consistent with rape and depict the defenda...
Article
Background: To inform the development of interventions to retain donors following a vasovagal reaction (VVR), the aim of this study is to use the Health Action Process Approach (HAPA) to identify predictors of intentions to re-donate and actual return behavior among whole blood (WB) and plasma donors who experienced a VVR. Study design and method...
Article
Background: Blood collection agencies (BCAs) worldwide are continuously looking to improve recognition, reward, and incentive (RRI) policies to optimize the recruitment and retention of blood donors. However, given the inconsistent categorization and variety of strategies available, there is a need for a theoretically informed and empirically supp...
Article
The victim’s testimony in most rape trials is unlikely to match jurors’ rape stereotypes and may instead seem typical of consensual sex. This research investigated whether providing judicial education about what commonly occurs in rape, and having a victim describe stereotype-consistent events early in their testimony, would guide jurors to interpr...
Article
Full-text available
Millions of charities compete for donations, yet no empirical study has examined patterns of shared giving behavior across the nonprofit sector. To understand which types of charities are more likely to share donors, we conducted a social network analysis using behavioral data from 1,504,848 donors to 52 large charities in Australia. Three hypothes...
Article
Full-text available
Advocacy is intended to change people's attitudes and behavior. Yet the psychological and behavioral consequences of advocacy have rarely been considered. Across 3 experiments (combined N = 934) in the contexts of debates around racial discrimination and abortion, we investigated if and how exposure to advocacy can influence collective giving respo...
Article
Diversification of blood collection agencies' (BCAs) core business requires donors to donate substances of human origin (SoHO) beyond whole‐blood. Whole‐blood donors are assumed to be willing to convert to donate other SoHO as well as whole‐blood. However, no reviews consider the evidence on conversion (i.e., willingness/intention, behaviour, reten...
Article
Full-text available

The aim of this survey was to assess the psychological impact of the pandemic on young professionals (YPs) in transfusion medicine. Materials and Methods A cross-sectional web-based survey w...
Article
Background and Objectives Maintaining a panel of committed anti-D donors is crucial for the production of anti-D immunoglobulin to prevent haemolytic disease of the foetus and newborn. Given low numbers of donors in the Australian panel, there is a need to better understand motivators and barriers specific to anti-D donors. Materials and Methods A...
Article
Full-text available
Introduction: As many countries change to opt-out systems to address organ shortages, calls for similar reform in Australia persist. Community perspectives on consent systems for donation remain under-researched, therefore Australian perspectives on consent systems and their effectiveness in increasing donation rates were explored. Design: In this...
Article
Jurors are less likely to believe a victim of rape when the events she describes are inconsistent with the rape stereotype and appear more consistent with what occurs in consensual sex. This research investigated whether presenting stereotype-consistent events early in a victim’s testimony can lead jurors to evaluate the other events described as d...
Article
Background Many blood collection agencies are generating important data on donor health outcomes using large-scale blood donor cohort studies. Such studies can be very effective when donors provide access to linkage of their data to external health databases, and storage and genomic testing of their blood sample. In this study, we aimed to assess t...
Article
Full-text available
Nonprofit organization (NPO) marketers are now increasingly turning online to recognize donors, with little understanding as to how online donor appreciation influences behavior. A scenario-based research design using an online survey was administered to a random sample of voluntary blood donors ( n = 356). The findings contribute to identity theor...
Article
Rationale Blood collection agencies face ongoing challenges in retaining voluntary donors to meet the demand for blood and blood-related products by healthcare services. A known deterrent to continued blood donation is the experience of a vasovagal reaction (VVR). However, there has been little research into donors’ experiences of these reactions a...
Article
Full-text available
Background Against a background of declining blood donor numbers, recruiting new donors is critical for the effective operations of healthcare providers. Thus, interventions are needed to recruit new blood donors. Purpose We provide initial evidence for Voluntary Reciprocal Altruism (VRA) to enhance nondonors’ willingness to become blood donors. V...
Article
Background and objectives With greater numbers of Australians living longer with healthier lives, older adults could make a greater contribution to whole‐blood and plasma donor panels. Understanding the experiences and attitudes of middle‐aged to older Australians towards blood donation may provide opportunities to develop strategies to engage, rec...
Article
Background Knowledge translation focuses on the transfer of research findings into policy and practice. To provide insight into the state of knowledge translation in blood donor research, we undertook a rapid review of a key research area in the field with high potential for translation, vasovagal reactions (VVRs). We examined the number and nature...
Article
Background: Fear of blood donation is implicated in vasovagal reactions, donor recruitment, and retention. This study examined the extent to which fear among donors is associated with various donor outcomes in an Australian sample, and whether fear can be addressed on-site to reduce adverse reactions and improve the donation experience. Study des...
Article
With the changing ethnic composition of the Australian population there has been a growing number of patients requiring transfusions of rarer blood types. People from ethnic minority groups are generally less likely to donate blood and this can lead to shortages for some patients from these communities. In this article we report the findings of a q...

Family discussion of donation wishes is a critical driver of family authorisation of organ donation. However, few people discuss their wishes or feel certain of family member’s donation preferences. Empirically, individual determinants of discussing donation wishes with family have been examined using the theory of planned behaviour (TPB). The impa...
Article
Intimate partner violence (IPV) is common and has a lasting negative impact on the health and well-being of victims and survivors. People’s mental frameworks (schemas) of IPV are central in allowing them to identify and respond to IPV. Early recognition of IPV is essential to reducing the cumulative harm caused by repeated instances of abusive beha...

Background This study compared the likelihood of return to donate and donation rate ratio by age of donors at their first donation when followed up to 12 years. Study Design and Methods Donation history of two cohorts of first‐time donors (those donating in 2007 and 2013) was extracted until March 2019 from Australian Red Cross Lifeblood's nationa...
Article
Victims of intimate partner violence (IPV) face significant barriers to having their complaints believed both when initially reporting their experiences and when giving evidence at trial. This is especially the case when they have been sexually assaulted by their partner. These barriers stem not only from misperceptions about what IPV is, but also...
Research
Shame, embarrassment and disgust may discourage people from donating stool or avoid the topic altogether. Within health communication, there is increasing interest in the role of humour to dispel these emotions or increase acceptance of unappealing or threatening information that elicits negative emotions. There is also evidence to suggest that hum...
Article
Background Blood collection agencies (BCAs) are expanding core business by inviting blood donors to donate stool for fecal microbiota transplantation (FMT). However, whether blood donors also want to donate stool is unclear since, despite its benefits, stool donation is viewed by many as unpleasant. This study examined the prevalence, contributors...
Preprint
Full-text available
The warm-glow of giving is one mechanism proposed to account for high levels of human cooperation. However, little is known about how warm-glow can be harnessed to sustain long-term cooperation to benefit wider society (vaccinations, blood donation). We argue that the power of warm-glow to sustain long-term cooperation cools offs over time but can...
Article
Background and Objective Recruiting and retaining male donors remain an ongoing challenge for blood collection agencies. Research suggests that interventions based on costly signalling theory that allows donors to unobtrusively but publicly signal their donor status may be effective. However, what functions as such a signal and how it is interprete...
Article
Full-text available
Background and objectives: Blood Collection Agencies in several countries have implemented strategies to increase the number of plasmapheresis collections. Despite this, a sizable minority of plasma donors lapse from donation each year, with little research conducted on this topic. An understanding of the plasma donation experience from the perspe...
Article
Background: Despite recognition that blood donation is an affectively poignant process, many aspects of donors' emotional experiences and their consequences remain unexamined. Purpose: This study tracked the donor's experience of several positive and negative emotions live as they arose during the donation process and tracked the impact of that...
Article
Full-text available
Millions of charities compete for donor dollars, yet why people prefer to give to particular charities remains poorly understood. Informed by the social identity approach, and using mixed methods, we analyzed open‐ended responses from a global donor survey (N = 1,849 from 117 countries) to understand why participants see their favorite charity as i...
Research
Embarrassment can lead to avoidance of potentially embarrassing situations and contexts. Stool donation is relatively unfamiliar to most people, and the substance itself or the act of donating may induce embarrassment or shame in potential or actual donors. As such, potential or actual donors may be deterred from donating stool because they feel sh...
Article
BACKGROUND: With the COVID-19 pandemic continuing to accelerate and blood collection agencies (BCAs) warning of shortages, it is critical to identify the current determinants of donor behavior for donors and non-donors. STUDY DESIGN AND METHODS: In May and June 2020, Australian residents who believed themselves eligible to donate blood responded...
Article
Background and Objectives In 2018, Australian Red Cross Lifeblood changed its plasmapheresis eligibility criteria to allow donors to donate plasma without the requirement of a prior successful whole blood donation. This study evaluated the impact of this policy change on donor retention and donor safety. Materials and Methods All donors who had at...
Article
While substantial research has been conducted on intimate partner violence (IPV), comparatively little research has examined peoples’ perceptions of which behaviors comprise this form of abuse. Early identification of IPV is critical to ending abuse, however, forms of IPV that typically occur earlier in a relationship (e.g., nonphysical abuse) may...

Study design and methods: On behalf of the Biomedical Excellence for Safer Transfusion (BEST) Collaborative, international blood collection agencies (BCAs) were invited to...
Article
Background and objectives: Encouraging existing plasma donors to donate more frequently is a key objective for blood donation services committed to expanding yield through voluntary non-remunerated plasmapheresis donation. This requires an understanding of donors' perspectives on their current donation practice and how this relates to their knowle...
Article
Background: Blood donor recruitment remains an important worldwide challenge due to changes in population demographics and shifts in the demand for blood. Various cognitive models help predict donation intention, although the importance of affective deterrents has become increasingly evident. This study aimed to identify fears that predict donatio...
Research
Thousands of patients globally with recurrent Clostridioides difficile would benefit from Faecal Microbiota Transplantation (FMT). However, the number of eligible volunteer stool donors do not meet demand, and it is challenging and costly to recruit donors. Based on a rapid review of FMT donor research, and brief reviews of complementary research (...
Article
Potential blood donors can be deferred due to concerns about the impact of the donation on their health or the safety of the blood supply. To date, we lack a comprehensive review of the impact of deferrals on donors and how to mitigate adverse effects. The aim of this review was to describe the available literature on deferrals, with a focus on the...
Article
Background: This study examined the impact of donor adverse events (DAEs) on plasma donor return and compared these against trends in whole blood (WB) donors. Study design and methods: Using a retrospective cohort design, donors who attempted to give plasma or WB in 2014-2015 were categorized by DAE and followed for 2 years. Analyses of return r...

Article
In the context of decreased demand for whole blood and increased demand for plasma‐derived products, donors in Australia are increasingly being asked to convert from whole‐blood to plasmapheresis donations. Plasmapheresis is a different type of donation to whole blood as the process takes longer and can be engaged in more frequently. What is unknow...
Article
In order for jurors to decide a legally correct verdict, they must comprehend and apply jury instructions. To date, empirical research has focused on jurors’ comprehension of instructions. However, it is difficult to know how well jurors actually comprehend instructions, because the tests currently used by researchers to measure jurors’ comprehensi...

Gender, age, religiosity, and political orientation are often associated with a propensity to give to charity. However, these broad associations mask inconsistencies that are not yet understood. Just as identity plays an important role in shaping consumer choices generally, donors’ identities could explain diverging associations between demographic...
Article
OBJECTIVES 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. BACKGROUND Social science research suggests that motivational orientations outlined by SDT can be usefully integrated with constructs from the TPB to collectively predic...
Article
Background Blood donation is a prosocial altruistic act that is motived by the mechanisms that underlie altruism (e.g. warm‐glow, reciprocity, fairness/trust). Because there is consistent evidence that altruism and its mechanisms show cross‐cultural variability, in the present paper we make the case for a cross‐cultural perspective in blood donor r...

Conference Paper
Full-text available
BACKGROUND: Titmus proposed that motivations underlying blood donation are intrinsically-altruistic. Although growing evidence suggests that this may not be the case, widespread recruitment and retention campaigns have been limited in an attempt to avoid crowding out intrinsic motivation. However, no method has been available to isolate those with...
Article
BACKGROUND Vasovagal reactions (VVRs) have a negative impact on donor safety and return. Applied muscle tension (AMT) increases blood pressure temporarily and has been suggested as a way to reduce donors' risk of VVRs. This study evaluated whether using AMT at three different time points during the donation procedure reduces the VVR symptoms report...
Article
Jurors often negatively evaluate complainants making allegations of rape when those complainants were intoxicated at the time of the assault. It is, therefore, essential that legal practitioners have effective methods of ensuring that jurors use evidence of intoxication for the legally permissible purpose, which is to determine the complainant’s co...
Chapter
Without volunteer blood a large proportion of healthcare delivery would not be possible. Blood donation is an archetypal altruistic and prosocial act, but like all altruism may also be motivated by selfish reasons. Key among these are the prosocial and moral emotions (e.g., gratitude, shame, guilt, anger). This chapter shows how blood donation can...
Article
Background and objectives: Effective recruitment and retention of male donors are vital for the ongoing provision of blood products. Compared with females, male donors are less likely to be medically deferred or experience vasovagal reactions and are typically preferred for plasmapheresis donation in voluntary non-remunerated settings. However, fe...
Article
Background: Incentives are often used to enhance the effectiveness of recruitment and retention campaigns targeting blood donors. However, the degree to which incentives succeed in attracting and facilitating repeat donation is unclear. A systematic literature review, following PRISMA guidelines, investigated the existing empirical evidence regard...
Article
This narrative review examines current research on risk factors, prevention methods and management strategies for vasovagal reactions (VVRs) that occur during or as a result of blood donation. VVRs are important to blood collection agencies (BCAs) as they negatively impact the number of completed collections, perceptions of the safety of blood dona...
Article
Donor retention is a key concern for blood collection agencies around the world. Despite a substantial body of research on facilitators of and barriers to donor return, few successful interventions to promote donor return have resulted. We suggest that insufficient attention has been paid to donor emotional experience. To address this, we outline t...
Article
Background: Research has documented beneficial effects of water loading (WL) and applied muscle tension (AMT) on reducing self-reported vasovagal reactions (VVRs) in whole blood (WB) donors. However, the optimal approach to reducing VVRs using these strategies in routine blood collection practice is not known. This study evaluated the effectivenes...
Article
Full-text available
Research consistently shows that techniques currently used to simplify jury instructions do not always improve mock jurors' comprehension. If improvements are observed, these are limited and overall comprehension remains low. It is unclear, however, why this occurs. It is possible that current simplification techniques do not effectively simplify t...
Article
Retained donors are safer and more cost effective than new donors, and yet increases in demand and natural attrition of the panel are typically countered through increased recruitment. An alternative would be to increase supply by persuading existing donors to donate more often. Many donors are medically eligible to do this; however, little is know...
Article
Background: Anxiety is a frequently cited barrier to blood donor recruitment. Although the mere presence of donation paraphernalia can heighten anxiety for some individuals, such stimuli are a necessary and unavoidable part of donation. Drawing on France and colleagues' research on tailored donor education and coping materials, the current study a...
Article
Accumulated research points to the therapeutic effects of including outdoor gardens in aged-care facilities, yet few facilities do so. Space and financial constraints are the major barriers to including them. Aspects of the indoor environment of residential aged-care facilities, such as they being too noisy, odorous, and lacking in warm interperson...
Article
Full-text available
Research has consistently shown that jurors are influenced by multiple schemas in cases of alleged sexual assault, including offense stereotypes and victim stereotypes. These schemas appear to be organized in a hierarchy, as victim stereotypicality seems to matter most in acquaintance assaults (counter-stereotypical offense). However, despite numer...
Article
Background: Research demonstrates that anxiety elevates the risk of blood donors experiencing adverse events, which in turn deters the performance of repeat blood donations. Identifying donors suffering from heightened state anxiety is important to assess the impact of evidence-based interventions. This study analyzed the appropriateness of a shor...
