title: A chimpanzee (Pan troglodytes) analogue of cross-national generalization of personality structure: zoological parks and an African sanctuary.
abstract: Six personality factors, including five resembling the human Big Five, had previously been identified in a separate group of zoo-housed chimpanzees. Comparability of chimpanzee personality factor structure was examined in two highly contrasting habitats: zoos and a large African sanctuary. Questionnaires for the zoo chimpanzees were in English, while most for the chimpanzees in the sanctuary were in French. Differences between the two settings were sufficiently extensive to make them analogous to cross-national human personality studies. Internal consistencies for five of the six factors did not differ between the two samples. The patterns of correlations between the unit-weighted factors were also similar for the two samples. Data from these two samples were pooled and factor analyzed. The resulting factor structure was then rotated to the factor structure described in the original study of chimpanzee personality. Dominance, Extraversion, Dependability, and Agreeableness had high congruences. Emotionality and Openness did not, but the items that had the highest loadings were consistent with the factors' definitions. Finally, sex and age effects for all factors generalized across habitats.
