Testing the Roles of Intergroup Anxiety and Inclusion of Animals in the Self as Mechanisms that Underpin the Pets as Ambassadors Effect

It has been suggested that pets provide the opportunity for humans to develop more positive attitudes and relationships toward a wider range of animal types-including toward non-pet animals-this is called the pets as ambassadors hypothesis. In this study, we build both on research conducted on human-animal relations and in social psychology to investigate the hypothesis, as well as two likely mechanisms involved in this effect: inter- group anxiety (toward animals) and inclusion of animals in the self. An online questionnaire was completed by 238 Canadian participants (M = 28.6 years old, SD = 8.53; 102 women). Using structural equation modeling (SEM), we tested a model whereby contact with pets predicted greater inclusion of ani- mals in the self and lower intergroup anxiety toward animals in general. In turn, these two psychological processes predicted more positive attitudes toward a broad range of animal types (e.g., wild/pest animals, animals used for human purposes) and animals in general. Finally, these positive attitudes toward animals predicted more pro-social behavioral intentions toward animals. The hypothesized model showed a good fit. Bootstrapping analyses further con- firmed the mediating roles of inclusion of animals in the self and intergroup anxiety toward animals in the associations between contact with pets and attitudes toward animals in general. The hypothesized model also presented a more satisfactory fit compared with an alternative model. Altogether, these findings underline the importance of contact with pets in fostering more positive human-animal relations and promoting animal welfare. These results also support the applicability of social psychological theories and principles in the realm of human-animal relations.
