Pfizer Animal Health/American Humane Association Study Benefits of Animal Assisted Therapy on Kids with Cancer


I am proud to say I was there when the American Humane Association and Pfizer Animal Health decided to combine efforts to study the benefits of animal assisted therapy (AAT) on pediactric cancer patients, and their families.

For years, medical professionals have touted the healing power of pets. There’s evidence of this from around the world, but having said that, there’s little data specifically regarding pediatric cancer. And while most expects concur, the presence of dogs is helpful – questions remain. How exactly are there presence a benefit? Under what circumstances? Are dogs more a benefit who are trained to do one thing more than another? Are certain families more or less targeted to benefit? Most of all, how does this mechanism work that dogs are able to reach into the soul of people undergoing treatment?

The research study, “Canines and Childhood Cancer: Examining the Effects of Therapy Dogs with Childhood Cancer Patients and their Families,” is a multi-year effort taking place in hospital settings across the U.S. that will examine the specific medical, behavioral, and mental health benefits AAT may have for children with cancer, and their families. A comprehensive literature review has been completed as a first step, and may be downloaded here.

In addition to the literature review, focus groups and interviews were conducted with hospital staff, family caregivers and animal-assisted therapy handlers, to glean vital information regarding childhood cancer epidemiology and treatment, the well-being of patients and families who are affected by childhood cancer, the applications of AAT for various populations in need, the state of AAT effectiveness research, and the considerations that need to be made when incorporating therapy animals into clinical settings.

Findings from the literature review, focus groups and interviews will help guide the design of the overall study. Preliminary findings showed that no standard protocol for an animal-assisted therapy session (i.e., length, number and type of participants in each session, session activities, or talking points) seemed to exist at any of the research hospital sites; each animal-handler team went about their work somewhat differently. This finding underlines the need for this study to develop consistent animal-assisted therapy treatment fidelity across sites in order to conduct the type of rigorous research needed in the human-animal interaction field.

The information gathered during this initial phase will serve to inform a scientific study design in order to conduct a pilot trial with three to five pediatric oncology sites across the country. Upon the conclusion of the pilot trial, researchers anticipate the launch of a full clinical trial across multiple sites for 12-18 months. During this time, certified therapy dogs and their handlers will conduct regular animal-assisted therapy sessions with pediatric oncology patients and their families, which will be evaluated by a range of biological, psychological and social measures.

“Now we begin the important work of validating and quantifying something that we have observed and felt for years through our own experiences — that interaction with animals can provide beneficial effects for people in need of comfort, encouragement and healing,” said Robin R. Ganzert, Ph.D., president and CEO, American Humane Association.

Results from the study will be widely disseminated through professional conferences and peer-reviewed journals in a diverse range of disciplines, including veterinary medicine, pediatric oncology, social work, and animal-assisted therapy.
