     When we treat an animal's welfare as an individual experience, we should consider the role of other individual differences in determining welfare. In this study, we tested whether personality and dominance status are associated with observer ratings of rhesus macaque (Macaca mulatta) welfare. Subjects were 44 socially-housed individuals residing at the California National Primate Research Center. For each subject, we obtained ratings on a 16-item welfare questionnaire, a 4-item subjective well-being questionnaire, and ratings on a 54-item personality questionnaire that enabled us to define each monkey's standing on the Confidence, Openness, Dominance, Friendliness, Activity, and Anxiety personality domains identified in an earlier study. Finally, we used focal animal sampling to obtain measures of behavior. We found evidence for interrater agreement for most of the welfare and subjective well-being questionnaires items, and these items defined a single dimension (welfareSWB). Using a mixed-effects model we found macaques with higher welfareSWB performed fewer stereotypies (e.g., pacing) (b = -0.42, P = 0.004) and displacement activities (e.g., scratching) (b = -0.31, P = 0.008). Using a linear model we found macaques with higher welfareSWB were younger (b = -0.67, P = 0.01) and rated as higher in Confidence (b = 2.11, P < 0.001). These results are consistent with previous reports on chimpanzees, brown capuchin monkeys, and associations between personality, welfare, behavior, and personality.
