The purpose of this study is to evaluate the effectiveness of the NIH Animal-Assisted Therapy (AAT) program on distress in oncology patients treated for pain. More than simply a physiologic or sensory response, pain is multidimensional. Pain management programs are best developed by selecting interventions based on the individual's pain experience. Strategies with several courses of action that complement each other may be selected to work together in a synergistic response to maximize pain relief. The goal of palliative care is to achieve the highest possible quality of life for patients, and indirectly, their families, through symptom control and attention to the whole patient: addressing physical, psychosocial, and emotional dimensions.
