“…A recent meta-analysis, using donor registration as the criterion variable, offers a different picture of the relationship between religion and donor status. Nijkamp, Hollestelle, Zeegers, van den Borne, and Reubsaet (2008) identified a positive relationship between religion and donor status by averaging across four studies on the topic, indicating that religious individuals were more likely to be registered donors.…”

The two-step flow model of communication (Katz, 1957) suggests opinion leaders obtain critical information from the mass media and, in turn, communicate this information to interpersonal contacts such as friends, family and co-workers. It is suggested that religious leaders (RLs) may serve as opinion leaders on the topic of organ donation by debunking donation myths, promoting donation during worship services, or communicating the benefit of donation to families faced with the opportunity to participate in living or cadaveric donation. The current study examined the personal knowledge, experiences, and willingness to communicate about organ donation in a sample of RLs (N ¼ 59) in Rochester, New York. Structured interviews were conducted in summer and fall of 2009 with a random sample of RLs. Results indicate a disparity between RLs' expressed personal support for donation and their engagement in donor registration. Approximately one-quarter of RLs have spoken about donation during a religious service and many indicate their knowledge is not sufficient to discuss organ donation in detail. Results elaborate on how RLs may be trained to serve as opinion leaders in the promotion of organ donation.

“…PBC, intention, behaviour). Indeed, Nijkamp et al [2] commented recently in their meta-analysis that they were prevented from analysing the role of intentions and perceptions of control in organ donation decisions as too few organ donation studies have included these constructs. Therefore, a test of the TPB using standard measures (as specified by Ajzen [26]) and observing the principle of compatibility is needed.…”

“…Participants' self-reported discussing behaviour (but not registering behaviour given low numbers of behavioural performers) was assessed 4 weeks later, with discussing intention as the only significant predictor of behaviour (Nagelkerke R 2 5 0.11). These findings highlight the impact of people's perceptions of a typical donor on their decisions to discuss their organ donation preference, assisting our understanding of the factors influencing individuals' communication processes in efforts to bridge the gap between organ supply and demand.Much organ donation research has examined the demographic factors, beliefs and attitudes that may explain the gap between organ supply and demand worldwide (see [1,2] for a review). Since 40-50% of family members deny consent for donation of their loved one's organs [3][4][5], a more recent focus has been on explaining this lack of consent [6].…”

Disclosing donation decisions: the role of organ donor prototypes in an extended theory of planned behaviour

This study explored the role of donor prototype evaluations (perceptions of the typical organ donor) in organ donation communication decisions using an extended theory of planned behaviour (TPB) model. The model incorporated attitude, subjective norm, perceived behavioural control, moral norm, self-identity, and donor prototype evaluations to predict intentions to record consent on an organ donor register and discuss the organ donation decision with significant others. Participants completed surveys assessing the extended TPB constructs related to registering (n 5 359) and discussing (n 5 282). Results supported a role for donor prototype evaluations in predicting discussing intentions only. Both extended TPB structural equation models were a good fit to the data, accounting for 74 and 76% of the variance in registering and discussing intentions, respectively. Participants' self-reported discussing behaviour (but not registering behaviour given low numbers of behavioural performers) was assessed 4 weeks later, with discussing intention as the only significant predictor of behaviour (Nagelkerke R 2 5 0.11). These findings highlight the impact of people's perceptions of a typical donor on their decisions to discuss their organ donation preference, assisting our understanding of the factors influencing individuals' communication processes in efforts to bridge the gap between organ supply and demand.Much organ donation research has examined the demographic factors, beliefs and attitudes that may explain the gap between organ supply and demand worldwide (see [1,2] for a review). Since 40-50% of family members deny consent for donation of their loved one's organs [3][4][5], a more recent focus has been on explaining this lack of consent [6]. Numerous aspects impact on the decision to give consent for donation (e.g. timing of the request, person making the request [7]). Prominent among these aspects is knowledge of a loved one's organ donation wishes. It has been demonstrated consistently that awareness of and previous discussion about a loved one's preference for donation increases the likelihood that consent for donation will be given [6,7]. To ensure that organ donation wishes are adhered to, then, an individual needs to make important others aware of their donation preference. Communicating organ donation wishes may involve documenting the decision on a donor register, driver licence or by other official means (registering) and/or talking with family members or next-of-kin about donation wishes (discussing). Few people, however, have disclosed their donation decision to family members [8][9][10][11].The extended theory of planned behaviour and prediction of donation decision disclosureSeveral studies [e.g. 8, 12-25] have used variants of major social-cognitive models, such as the theory of planned behaviour (TPB) or its predecessor the

“…At this phase of the decision-making process, a person's beliefs and attitudes play an important role in their chosen donation preference (Radecki & Jaccard, 1997). Accordingly, numerous international investigations have explored individuals' organ donation beliefs (Nijkamp, Hollestelle, Zeegers, van den Borne, & Reubsaet, 2008;Radecki & Jaccard, 1997), including altruistic, (Morgan & Miller, 2001;Skowronski, 1997) practical, (Sanner, 1994;Skowronski, 1997;Yeung, Kong, & Lee, 2000) and religious/spiritual (Kececioglu, Tuncer, Yucetin, Akaydin, & Yakupoglu, 2000;Lam & McCullough, 2000;Parisi-Rizzo, 1987;Radecki & Jaccard, 1997;Skowronski, 1997) beliefs encouraging donation. However, many beliefs about organ donation are negative and reflect a lack of knowledge about and discomfort with the donation process.…”

Do the myths still exist? Revisiting people’s negative beliefs about organ donation upon death

The prevalence of myths preventing people partial to donation in Australia from consenting is unknown. Respondents (N = 468: 381 donors, 26 non-donors, 61 undecided) were surveyed about their (negative) donation beliefs. Approximately 30% of donors were neutral or supported negative beliefs about organ allocation, especially donation to undesirable organ recipients and a black market organ trade. Confusion about brain death, lack of family and religious support, and discomfort with donation were negative beliefs endorsed by some respondents irrespective of donor preference. Proportionally, donors had greater trust in hospitals/doctors than other groups. Some myths still exist but may vary with donation preference.
