IntroductionPlasmapheresis donors’ recruitment strategies should focus on asking whole-blood donors (WBDs) to convert to plasmapheresis.ObjectiveThis study measured the effect of labeling on the conversion of WBDs to plasmapheresis donation and examined the relationship between the type of blood drive and conversion to plasmapheresis.MethodsTwo blood drives destined towards students were held either on a university campus (mobile blood drive), or in a blood center. At the end of each whole-blood donation, the nurse performed a labeling, reactivated a few minutes later by a second individual asking the donor if he would agree to donate plasma. If so, an appointment for plasma donation was made or a promise was collected. The number of commitments to plasmapheresis (promise/appointment) and the number of achievements of these commitments measured the effect of labeling.ResultsFew significant differences between social or functional labeling were found compared to a “no labeling” condition in terms of commitments and concretizations. The in-center blood drive achieved three times more engagements than the mobile blood drive (p < .001). Appointments had better chances to turn into a plasma donation than promises (p < .001).ConclusionLabeling as it was tested seemed ineffective in conversion from whole blood donation to plasmapheresis, but further studies should be carried out to replicate these results. When only collected during in-center blood drives, blood collection agencies should try to develop in-center whole blood donations and promotional approaches towards plasma donation. When approaching potential plasmapheresis donors, appointments should be preferred to promises. Further research is needed to examine the causes of these results.  相似文献

The experience of vasovagal reactions during blood donation (e.g., faintness, dizziness, lightheadedness) can be a deterrent to repeat donation. Because these reactions are associated with decreases in blood pressure, caffeine was examined as a potential modulator of vasovagal reactions by virtue of its pressor effects. Using a randomized, double-blind design, 62 female undergraduate 1st-time blood donors received either 0, 125, or 250 mg of caffeine prior to blood donation. Participants who received 250 mg of caffeine had lower scores on the Blood Donation Reactions Inventory, required fewer interventions by phlebotomists for negative reactions, and reported a greater likelihood of repeat donation than participants who received placebo. These findings suggest that a moderate dose of caffeine attenuates negative reactions in novice female blood donors and may increase the likelihood of repeat donations.  相似文献

A field experiment investigated the accuracy of blood donor's memory for the emotions they experienced during blood donation. Compared to what they reported at the time of donation, the donors remembered a greater contrast between predonation and postdonation emotions. The donors also remembered experiencing more anxiety than they actually did. The bias in memory was especially pronounced among relatively inexperienced donors who had not been asked to report on their emotion prior to their actual donations. The memory boas was also related to donors' attitudes at the time of recall. Donors' intentions to donate blood again were reliably predicted by a combination of attitude and emotion measures. Discussion considers a potential intervention for improving donor return rates.  相似文献

ObjectivesThis study aimed to extend recent work on the effects of goal types in physical activity (PA; Swann, Hooper et al., 2020) by comparing the effects of SMART, open, and do-your-best (DYB) goals on performance and psychological responses in active and insufficiently active adults in a walking task.Design4 (goal condition) x 3 (attempt) x 2 (group) mixed design.MethodsActive (n = 18) and insufficiently active (n = 18) participants completed baseline and two experimental attempts of a 6-minute walking test in four conditions: SMART goal; open goal; DYB goal; and control. A range of measures were taken during and following each attempt, and after each session. A series of mixed ANOVA’s were conducted for all measures assessed between groups.ResultsInsufficiently active participants achieved greater distances in the open condition compared to the SMART condition (p < .001), whereas active participants achieved greater distances in the SMART condition compared to the open condition (p < .001). Additionally, exploratory analyses revealed that insufficiently active participants reported greater pleasure and enjoyment (p < .05) in the open condition compared to active participants, who conversely reported more pleasure and enjoyment (p < .05) in the SMART condition than insufficiently active participants.ConclusionsFindings provide initial evidence that PA and psychological responses differ between active and insufficiently active individuals depending on goal type. This work has potential implications for goal setting strategies in PA promotion and raises further questions about current practices of setting SMART goals for insufficiently active participants.  相似文献

OBJECTIVES: Blood donation is described as an archetypal altruistic behavior, and recruitment/retention campaigns emphasize altruism. Here, a benevolence hypothesis for blood donation (both the donor and recipient benefit) rather than the altruism hypothesis (only the recipient gains) is proposed. DESIGN: Three United Kingdom-based studies contrasted benevolence and altruism: (a) a 6-month prospective study of blood donor behavior (Study 1: N = 957), (b) a cross-sectional study of blood donors' intentions (Study 2: N = 333), and (c) an experimental study examining the effect of benevolent and altruistic messages on willingness to help across high- and low-cost helping behaviors for committed and noncommitted blood donors (Study 3: N = 200). MAIN OUTCOME: Donor behavior and intentions-willingness. MEASURES: Beliefs in personal and societal benefit (Time 1) and actual donations (Time 2) were assessed in Study 1; beliefs in benevolence, altruism, hedonism, and kinship along with donation intentions were assessed in Study 2; and empathy, donor commitment, and willingness to donate blood, money, fund-raise, and staff a telephone helpline were assessed in Study 3. RESULTS: Beliefs in personal rather than societal benefit predicted actual future donation. A path model showed that only beliefs in benevolence were associated with intentions to donate. Committed blood donors were more willing to donate blood when exposed to a benevolent message rather than an altruistic one. This effect was not observed for other forms of helping. CONCLUSIONS: The benevolence hypothesis is supported, suggesting that blood donor motivation is partly selfish. Blood donation campaigns should focus on benevolent rather than purely altruistic messages.  相似文献

We tested the Door-in-the-Face technique (DITF) on blood donation with a delay between the acceptance of the request and the real possibility of complying with it. University students were solicited to give blood during a special one-day drive. After the refusal to participate in a long-term donor program, participants were asked for a one unit blood donation. In the control condition, only the latter request was addressed. The participants were either solicited two or three hours before the blood drive (delay) or during the blood drive (no delay). Results showed the DITF technique to be associated with greater verbal compliance with the request. However, the DITF technique with no delay was associated with greater behavioral compliance than were both of the control conditions and the DITF with a delay condition.  相似文献

We extend research on charity donations by exploring an everyday tactic for increasing compliance: asking politely. We consider three possible effects of politeness on charity donations: a positive effect, a negative effect, and a wiggle‐room effect where the perception of the request is adjusted to decline donating without feeling selfish. Results from six experiments systematically supported the polite wiggle‐room effect. In hypothetical donations contexts, indirect requests were judged more polite. In real donation contexts, though, indirect requests were not judged as more polite and had no consistent effect on donation decision. Rather, the decision to donate predicted the perceived politeness of the request, independently of its phrasing. Experiment 4 provided causal evidence that participants justified their donation decisions by adjusting their perception of the request. The polite wiggle‐room effect has important implications for organizations that seek to increase compliance while maintaining a positive image.  相似文献

This quasi-experimental longitudinal study assessed the effect of a one-day Cognitive Behaviour Therapy (CBT)-based workshop on work-related rumination, chronic fatigue, and sleep quality. We hypothesized that participants who attended the workshop would report lower levels of affective work-related rumination, chronic fatigue, and improved sleep quality, at follow-up, 6 months after workshop completion. Two hundred and twenty-seven participants took part in the study, with 102 participants attending a one-day workshop delivered in their workplace. Participants completed an online questionnaire at two time-points, with follow-up occurring 6 months after initial survey completion. Results showed that participants who took part in the CBT workshop reported significantly lower levels of affective rumination (p = .03) and chronic fatigue (p = .003), at follow-up in comparison with individuals who did not attend the workshop; however, there were no significant differences between the groups in self-reported sleep quality (p = .06). A combination of more effective recovery both at work and outside of work may explain the reductions in both affective rumination and fatigue over time. This study adds to the recovery from work literature by providing initial support for a one-day CBT-based workshop delivered in the workplace.  相似文献

Are disaster relief appeals more successful if they emphasize the material cost of disaster events in terms of economic damages and need for shelter, food, and health care, or if they emphasize the human cost in terms of psychological suffering and trauma caused? Although giving patterns seem to suggest that large-scale events that cause widespread material damage (e.g., the Asian Tsunami of 2004) are more successful at eliciting donations than smaller scaled events, it is argued that this pattern is explained by the fact that large perceived material damage leads to more perceived human suffering. In other words, it is the perceived human suffering which is the proximal driver of donations, rather than the material damage itself. Therefore, relief appeals that emphasize the human cost of events are more successful at eliciting donations than appeals that emphasize the material cost of events. This was demonstrated in a study focusing on donations by British participants (N = 200) to the Syrian refugee crisis in 2020, a study focusing on donations by British participants to victims of severe weather events in Eastern and Southern Africa in 2020 (N = 210), and a study among British participants focusing on a fictitious event (N = 150).  相似文献

In an attempt to replicate the findings reported in this Journal by Weyant and Smith (1987), members or recent donors to a Canadian civil liberties organization were asked to donate money under one of three conditions: (a) In the control condition, they were simply asked for a donation; (b) in the “smaller request” condition, they were asked to make a donation, but amounts of Canadian $30 to $100 were suggested; and (c) in the “larger request” condition, amounts of $50 to $250 were suggested. Unlike the Weyant and Smith studies, we found no difference in the proportion of respondents making a donation, but significant differences in the size of the donations made by those making donations. In our study, the most effective way of getting large donations was to ask for a large amount. It was suggested that the most likely explanations for the differences in the results of the two studies were the following: First, our target population were previous donors to the organization, whereas those in the Weyant and Smith studies were not likely to have been. Previous research suggests that those who had been donors previously are influenced, positively, by requests for a specific large donation, whereas those not previously approached are, if anything, negatively influenced. Second, our “larger request” appears to be within a plausible range for donations, whereas the larger request in the Weyant and Smith study may have been seen as being outside of the plausible range. In any case, however, we would recommend caution in drawing a conclusion about the most effective request size to encourage people to donate money to charity.  相似文献

OBJECTIVE: Compare the efficacy of a multicomponent social support intervention to standard-of-care counseling on medication adherence among HIV-infected patients initiating antiretroviral therapy. DESIGN: Randomized controlled trial. Generalized estimating equations tested for differences in the percentage of participants achieving 90% adherence. MAIN OUTCOME MEASURES: Pill-taking, electronically monitored over 6 consecutive months; plasma viral load (VL), assessed at 3 and 6 months following initiation of therapy. RESULTS: Of 226 participants who were randomized and began the trial, 87 (38%) were lost to the study by 6 months. The proportion of adherent participants declined steadily over time, with no time by group interaction. Sustained adherence was associated with increased odds of achieving an undetectable VL (OR=1.78; 95% CI=1.01, 3.13). In intention-to-treat analyses, a larger proportion of the intervention group than the control group was adherent (40.15% vs. 27.59%, p=.02) and achieved an undetectable VL p=.04). However, the majority of participants who remained on study experienced some reduction in VL (>or=1-log drop or undetectable), regardless of experimental condition. CONCLUSION: The multicomponent social support intervention significantly improved medication adherence over standard-of-care counseling; evidence for improved virologic outcomes was inconsistent. Early discontinuation of care and treatment may be a greater threat to the health of HIV patients than imperfect medication-taking.  相似文献

Blood-donation-related symptoms such as dizziness and weakness discourage people from participating in this important health-related activity. Four hundred sixty-seven young adult, French-speaking blood donors were randomly assigned to (a) a condition in which they learned a possible preventive technique called applied tension and were asked to practice it from the time they got on the donation chair until they were just about to get up, (b) a placebo condition in which they learned applied tension and were asked to practice it from the time they got on the chair until the insertion of the donation needle, or (c) a no-treatment control condition. Donors assigned to the treatment condition reported significantly fewer blood-donation-related symptoms than did donors assigned to the other conditions and rated their likelihood of returning to give blood again as greater than did those in the no treatment condition. Among donors whose chairs were not reclined, participants in the treatment condition had significantly smaller heart rate reactions to blood donation than did those in the other conditions.  相似文献

This study assessed the effectiveness of an intervention based on a theoretical framework of citizenship on reducing psychiatric symptoms, alcohol use, and drug use, and increasing quality of life for persons with serious mental illness (SMI) and criminal justice involvement. One-hundred fourteen adults with SMI and a history of criminal justice involvement participated in a 2 × 3 longitudinal randomized controlled trial of a four-month citizenship intervention versus usual services. Linear mixed model analyses were used to assess the intervention’s impact on quality of life, symptoms, and substance use. After controlling for baseline covariates, participants in the experimental condition reported significantly increased quality of life, greater satisfaction with and amount of activity, higher satisfaction with work, and reduced alcohol and drug use over time. However, individuals in the experimental condition also reported increased anxiety/depression and agitation at 6 months (but not 12 months) and significantly increased negative symptoms at 12 months. Findings suggest that community-oriented, citizenship interventions for persons with SMI and criminal justice histories may facilitate improved clinical and community outcomes in some domains, but some negative clinical findings suggest the need for post-intervention support for intervention participants. Implications for practice and future research are discussed.  相似文献

The success of non-profit organizations depends mainly on the strategies they use to recruit new donors. One common strategy is to solicit donations upfront (mostly online)—but is this indeed an effective approach? We conducted three experiments (Ntotal?=?1287), in which we compared an upfront appeal of that sort with one that offered prospective donors the opportunity to express their opinion about a given fundraising campaign—and then asked if they cared to donate to it. Drawing on foot-in-the-door and escalation of commitment theories, we found that soliciting an opinion (as opposed to a donation) led to greater engagement with the charity among prospective donors, as reflected by their greater willingness to read about the cause. This, in turn, encouraged them to donate. In experiment 1, we showed that the direct effect of request type on donations was mediated by the donors’ willingness to learn about the charity. In experiment 2, we showed that pairing an appeal for an opinion with a donation request was more effective than merely appealing for a donation. Finally, in experiment 3, we found that the more donors learn about a given cause, the stronger their emotional response to it, and the greater their donations to it. Further, we showed that soliciting an opinion (as opposed to a donation) made donors feel a greater connection with the organization. In sum, we propose a simple and cost-effective intervention that may help non-profit businesses become more effective.

A field experiment conducted in high schools throughout the country was aimed at increasing the number of high school students who donate blood. Special interventions that emphasized psychological or educational approaches to heightening motivation to donate, as well as a combined intervention, were compared with the usual approach taken at blood drives. Psychological interventions in which social learning principles (modeling, perceptions of social norms) played important roles either alone or in combination with an educational (informational) approach were more successful in stimulating blood donations than either an educational approach alone or the approaches traditionally followed by the participating local blood centers. The results demonstrated that use of social learning principles in designing interventions to strengthen socially relevant altruistic behavior could be valuable both practically and theoretically.  相似文献

Predictors of monetary donations to victims of humanitarian disasters were examined. Participants (N = 219) chose between donating to different scenarios and justified their choices in an open response format. This was followed by a questionnaire. The perceived extent of the victims’ Need, the Impact of a potential donation, and the Amount donated by others all influenced donation decisions. There was a three‐way interaction between these factors: The perceived Need for help only mattered if the perceived Impact of a donation was high, and the perceived Amount donated by others was small. Implications for theory and practice are discussed.  相似文献

It is suggested that for social psychological theory and research on helping to provide an adequate general explanation of helping, more attention must be paid to supraindividual factors. Most studies of blood donation have failed to take into account a number of factors that may influence donations at the level of the organization, community or collectivity. This study examines the possibility that specific community norms may emerge that have an influence on the donating behavior of community members. Perceived normative support was found to exist in different degrees in communities that provide different levels of behavioral support for bloodmobile visits, and persons who report a greater degree of perceived community support for donation are more likely to have donated in the past year. Implications for donor recruitment procedures are discussed.  相似文献

Social Identity Theory and the concept of social comparison have inspired research on individuals, addressing effects of personal and environmental factors in directing social attention. The theory's conceptual origins, however, suggest that social comparison may have behavioral implications as well. Such behaviors may include attempts by an individual to enhance the relative status of his ingroup on a salient dimension of comparison. Such behavior is referred to as "social competition." In two studies, the effects of social comparison and social competition were measured in the real-world environment of community food drives. Participants were aggregated by household; 600 households in upper middle-class neighborhoods in Eugene and Salem, Oregon, were contacted. In Study 1 of 300 households, it was hypothesized that inclusion of a social competition cue in requests for donation would significantly increase the likelihood of donation. This hypothesis was supported. Study 2 was done to clarify the possible role in a social comparison of perceived ingroup inferiority in the prior observed increase in donations. The inclusion of a social comparison cue in the donation request significantly increased donations in households of the second study. The findings suggest that researchers should expand study of the theory's behavioral implications, including the role of social comparison in prosocial behavior.  相似文献
