Several scales are used to evaluate the quality of life in medicine and psychology of human beings, but the use in zoology is not common. The objective of this work was to evaluate the stress and the quality of life of capuchin monkeys through behavior tests and their relationship with biological stress markers. Laboratory stress assessment was estimated using six biomarkers collected from a single sample. The quality of life questionnaire was applied to three caregivers and included questions related to physical health, stress, and coping, social relations, psychological stimulation, and positive and negative indicators of quality of life. The higher the score of this scale, the worse the quality of life of the animal. To study the influence of the autonomic nervous system on the heart and risk of sudden death, the Heart Rate Variability (HRV), the Cardiovagal Index (CVI) and the Cardiosympathetic Index (CSI) were calculated. There was a significant correlation between the scale and serum cortisol and CRP of the animals, with a coefficient of 0.69 and 0.80, respectively (p< 0.05), which characterized positive, significant, and robust correlation in both variables.
