Trust is assumed to be important for charitable giving. However, disparate associations have been found, and recent theoretical approaches emphasize motives for giving that do not rely on trust. To resolve this tension, we conducted a systematic review of evidence generated between 1988 and 2020. A meta-analysis of 69 effect sizes from 42 studies sampling 81,604 people in 31 countries confirmed a positive association between trust and giving across diverse measures, r = .22. Meta-regressions showed that organizational (r = .35) and sectoral trust (r = .27) were more strongly associated with giving than were generalized (r = .11) or institutional trust (r = .14). The relationship was also stronger in non-western (vs Western) countries and in nonrepresentative (vs nationally representative) samples. All evidence was correlational, and few studies measured actual behavior. We discuss implications for theories of trust and for fundraising practice, and highlight critical gaps in evidence.

假定信任对于慈善捐赠很重要。但是，已经发现了完全不同的关联，并且最近的理论方法强调了不依赖信任的给予动机。为了解决这种紧张关系，我们对1988年至2020年期间产生的证据进行了系统回顾。对来自31个国家/地区的81,604名样本的42项研究的69种效应大小进行了荟萃分析，证实信任与各种衡量指标之间存在正相关关系，r =。 22 元回归表明，组织捐赠（r = .35）和部门信任（r = .27）与捐赠的关联性比广义（r = .11）或机构信任（r= .14）。在非西方（相对于西方）国家和非代表性（相对于国家代表性）样本中，这种关系也更强。所有证据都是相关的，很少有研究测量实际行为。我们讨论了对信任理论和筹款实践的影响，并强调了证据方面的重大差距。
