The purpose of this paper is to link subjective data obtained from a questionnaire survey with blood donation behavioral data, constructs a conceptual model of the factors that influence repeated blood donation behavior, and explores the mechanisms and degrees of influence of the value and cost elements of blood donors on repeated blood donation behavior.

First, this study constructs a conceptual model of the factors that affect repeated blood donation based on delivered value theory. Second, this paper is driven by subjective data obtained from a questionnaire and big data on blood donation behavior; the use of multisource data can help us understand repeated blood donation behavior from a broader perspective. Through data association and systematic research, it is possible to accurately explore the mechanisms through which various factors affect repeated blood donation behavior.

The results show that among the value elements, personnel value (PV), image value and blood donation value affect blood donation behavior in decreasing order. The change in PV per unit directly caused a 0.471-unit change in satisfaction, which indirectly caused a 0.098-unit change in donation behavior. Among the cost elements of blood donors, only the impact of time cost (TC) on repeated blood donation behavior was significant, and a change of one unit in TC caused a change in repeated blood donation behavior of −0.035 units. In addition, this paper groups subjects according to gender, education and age and explores the differences in the value and cost factors of different groups. Finally, based on the research results, the authors propose corresponding policy recommendations.

First, the authors expand the application field of the delivered value theory, and provide a new perspective for studying repeated blood donation. Second, through questionnaire data and blood donation behavior data, the authors comprehensively explore the factors that influence repeated blood donation behavior.

The purpose of this paper is to explore the impact of WeChat public platforms (abbreviated as WPP) on blood donation behavior using data from the platforms’ backend and information system.

First, this paper established a time-varying difference-in-difference (DID) model to evaluate the change before and after following the WPP under normal scenarios. The difference-in-difference-in-difference (DDD) method was further used to analyze the heterogeneous effects of gender, age, occupation and education. Second, a logit model was used to examine the impact of WPP on blood donation behavior under emergency scenarios (i.e. COVID-19).

The research shows that following WPP has a positive impact on donation volume. For each donor, the average blood donation volume after following WPP increased by 12.94% compared to before following. The WPP has a greater impact on groups with males, medical staff, middle-aged individuals and those with primary school education. Following WPP also enhanced blood donation behavior in emergency scenarios. During the COVID-19 pandemic, the probability of fans donating blood was 2.6% higher than non-fans, and the average blood donation volume of fans was 7.04% higher than non-fans, which was 5.9% lower than in normal scenarios.

For theory, this paper quantified the impact of WPP on blood donation behavior in normal and emergency scenarios and addressed the research gap surrounding the impact exerted by social media on blood donation behavior. For methodology, the time-varying DID model, DDD model and logit model were applied to the field of blood donation, which expanded the application scenarios. For practice, the findings are of great significance for recruiting blood donors and providing evidence for promotion on WPP.

The purpose of this paper is to explore the impact and mechanism of WeChat public platforms articles (abbreviated as WPP) on blood donation behavior using data of WPPA and donation behavior data.

This paper uses multiple linear regression methods, web crawlers and natural language processing technology. It first quantifies the impact of WPP published articles on donation behavior. On this basis, it then selects data from the day of article publication to further study the impact of article dissemination on donation behavior from the perspective of reading quantity, and analyzes the influencing factors of article reading quantity.

The results show that on the same day that an article is published, there is an increase of 13.8 and 14.3% in blood donation volume and fan registrations, respectively. The mediating effect exists. However, the day after an article is published, there is no longer any effect on blood donations. With a 1% increase in reading quantity, blood donation volume on the day of article publication increases by 0.13%, and this positive impact is promoted by the quality of the articles. A conc ise articles title and body and rich images help drive reading quantity. Moreover, blood donors prefer to read articles about blood dynamics and donation promotion, while articles about news, announcements and administrative affairs make them less inclined to read.

First, it focuses on WPPA, quantifies the impact of articles on blood donation behavior and analyzes the mechanism. Second, the authors study the impact and timeliness of social media article dissemination to address the insufficiency of existing research. Third, the study provides a scientific basis for the editing and publishing of articles, helping blood banks improve the effectiveness of publicity and recruitment.

Although blood banks have recently started to recruit blood donors through social media platforms, including WeChat, to increase recruitment effectiveness, few researchers have studied their effects on blood donation behavior. The aim of this study is to examine the influence of using official WeChat accounts on repeat blood donation behavior.

This paper used the backstage operation data of official WeChat accounts and blood supply chain management system data from the blood bank for the study to analyze the changes in repeat blood donation behavior. First, to analyze the changes in the average frequency of blood donation per year, average volume of single blood donation and blood eligible rate of repeat blood donors before and after following the official WeChat accounts by difference-in-differences model combined with propensity score matching (PSM-DID). Second, we examined the impact of official WeChat accounts on the proportion of repeat blood donors through survival analysis.

The results show that following WeChat accounts increases the average frequency of blood donation and blood eligible rate of repeat blood donors by 14.36% and 1.19%, respectively, and have no significant effect on the average volume of single blood donation. Further, WeChat accounts have a more significant impact on the average frequency of blood donations per year for workers, farmers, medical staff and groups with education levels of junior high school. In addition, official WeChat accounts can effectively increase the proportion of repeat donors.

The results provide a quantitative basis for the influence of official WeChat accounts on repeat blood donation behaviors. On the one hand, it is of great significance to guide the publicity and recruitment of unpaid blood banks. On the other hand, it provides an evidence for the promotion of official WeChat accounts.

The rapid development of the Internet in China has profoundly affected the country's charities, which many people support through online donations (e.g. providing financial help) and charity information forwarding (a new behavior of participating in online charities via social media). However, the development of online charities has been accompanied by many problems, such as donation fraud and fake charity information, which adversely affect social kindness. The purpose of this paper is to understand people's online donation and forwarding behaviors and to explore the mechanisms of such behaviors from the perspectives of cognitive-based trust and emotional-based empathic concern.

This study developed a research model based on the elaboration likelihood model (ELM) and stimulus–organism–response (SOR) model. The researchers obtained 287 valid samples via a scenario-based experimental survey and conducted partial least squares structural equation modeling (PLS-SEM) to test the model.

The results indicated that (1) online donation intention is motivated by rational-based trust and emotional-based empathic concern; (2) online charity information forwarding is triggered only when trust is built, and there is no significant correlation between empathic concern and forwarding intention; and (3) content quality, initiator credibility, and platform reputation are three critical paths to promote trust; in addition, an individual's empathic concern can be motivated by the emotional appeal.

This study highlights the different mechanisms of donation and forwarding behaviors and provided theoretical measures for motiving trust and empathic concern in the online context to promote people's participation in online charity.

The purpose of this paper is to test whether, in the context of blood donation, the predictive ability of the theory of planned behaviour (TPB) extends from behavioural intention to actual donation behaviour, and whether extended versions of the TPB perform better than the standard version.

Intentions to donate blood predicted by the TPB are compared with an accurate measure of blood donation behaviour obtained following a mobile blood drive by the New Zealand Blood Service.

When the observed outcome is donation behaviour rather than behavioural intention, the TPB model's performance drops. Extending the variables in the model to include moral obligation and past behaviour does not improve its predictive ability, and neither does the use of belief‐based variables.

The TPB is much less effective in predicting blood donation behaviour than it is in predicting intentions to donate blood. But only actual donation behaviour yields medical supplies. This study suggests that to advance the goal of increasing donation rates, attention needs to turn to methods other than the TPB to identify variables that do predict donation behaviour.

The present study gathered one of the largest samples used for TPB blood donation research; this enabled predictions made using the TPB to be tested against actual behaviour, rather than behavioural intention, the measure typically used in blood donation studies. Because blood donation is a low‐incidence behaviour, previous studies have been hampered by small sample sizes, that inevitably contain few donors, and no measure of actual donation behaviour.

Playing exergames may resemble doing conventional exercise and thus has the potential to enhance users’ health. However, no study has yet examined whether and how a need for exercise impacts users’ intention to continuously play exergames, i.e. continuance intention and its antecedents. We developed a model grounded in the uses and gratifications theory (UGT) to address this issue.

We recruited 583 participants to play exergames and collected their psychological responses and physical information. Structural equation modeling (SEM) was used to test the hypotheses.

We found that health consciousness and perceived exercise benefits are positively related to a need for exercise, which is, in turn, positively related to continuance intention. Moreover, perceived exergame similarity with exercise strengthens the positive link between the need for exercise and continuance intention.

This is the first study using the UGT to explain the underlying mechanism linking health consciousness to continuance intention in the playing of exergames. In addition, we introduced the need for exercise as a novel construct in this study. Our findings provide insights to managers on incorporating health-related features into their exergame products to motivate users' engagement in playing exergames.

The purpose of this paper is to demonstrate that there are three major blood donor segments in China, namely benefit‐oriented donors, altruistic donors and health salience donors, with the use of factor‐cluster segmentation approach. It also investigates the blood donation attitudes, group characteristics, and preference for information acquisition of the identified donor segments.

A factor‐cluster segmentation approach was used in this study. A questionnaire survey on Chinese respondents who had just completed a blood donation process was conducted in China and 7‐point Likert‐type questions were used to measure the respondents’ attitude toward blood donation, their motivation to donate blood, lifestyles, demographics and information acquisition. K‐means non‐hierarchical clustering method was used to segment groups of blood donors. ANOVAs were conducted to assess the differences regarding the blood donation factors across the cluster segments.

Results demonstrate that there are three blood donor segments as predicted. Benefit‐oriented donors are found to be the largest cluster (42.6 per cent), followed by altruistic donors (29.6 per cent) and health salience donors (27.8 per cent). The three clusters of donors show some extent of differences in attitudes toward blood donation, lifestyles and preference for information acquisition.

Through a better understanding of the donor segments, a more effective marketing communication strategy can be formulated. This can promote more blood donation by the first‐time and repeat blood donors and may save many more lives in a society.

The major advertising appeal for blood donation is altruistic in nature, particularly in Western countries. However, in other emerging countries such as China, some other appeals may be even more effective. Benefit appeal or health fitness appeal may be a better option in marketing communication strategy.

Imbedded in the life course paradigm, the purpose of this paper is to investigate which individual life events impact blood donations and to study their underlying mechanisms.

By applying logistic regression, moderation and mediation analysis, this paper uses a large sample of N = 5,640 individuals.

Experiencing normative life events and stressful life events reduce the likelihood of donating blood, whereas human capital life events enhance the likelihood of donating blood. Specifically, having a child and death of a mother decrease and finishing education increases the probability of blood donations. Locus of control and satisfaction with income are significant underlying mechanisms.

Social marketing campaigns can use individual life events to focus on similarities between potential blood donors and individuals in need of blood. Blood centers can adopt their services to cater to the changing needs after experiencing individual life events by running mobile blood collecting drives and providing guidance.

Blood centers take an important role in sustaining a healthy society. As the need for blood will increase in the future, a better understanding of blood donation behavior and social marketing contributes to increased donations.

While previous research looked at collective life events, there is a dearth in marketing and blood literature on the effects of individual life events.

The main purpose of this research is investigating the role of religion in sculpting blood donation behavior in younger adults by using the theory of planned behavior (TPB).

A structured questionnaire was developed to collect data, and in total, 242 questionnaires of undergraduate students from four large universities in Iran were analyzed. The suggested research model was tested by structural equation modeling.

The findings indicate that religious beliefs have a positive influence on the attitude toward blood donation. Therefore, it seems that the influence of religion on prosocial activities such as blood donation is considerable. Moreover, attitudes, perceived behavioral control and subjective norms have a positive influence on the intention to blood donation. The research findings are consistent with the TPB model.

Previous research on blood donation has not considered religious beliefs in the TPB. The contribution of this study is examining the relationships between attitude and behavior with respect to religious beliefs as a silent shaping agent of attitude.
