We examine the link between social network size and forgiveness, as well as mediating effects of self-efficacy and trust. Data are from the Detroit Community Study, which include three racial/ethnic groups: African Americans, Arab Americans, and White Americans (N=907). Results indicated that larger network size is associated with more forgiveness, but is mediated by trust. Patterns varied within racial/ethnic group: among Arab Americans self-efficacy mediated the effect of network size on forgiveness; among African Americans there were no direct or mediating effects; among White Americans an indirect effect of trust on forgiveness was identified. Findings suggest complex associations with forgiveness.
