New Research to Explore Effects of Service Dogs on Children with Autism Spectrum Disorder and Their Caregivers

A preliminary study led by researchers in the Purdue University College of Veterinary Medicine has shown that overall symptoms of post-traumatic stress disorder are lower among war veterans with service dogs. The pilot study was co-funded by the Human Animal Bond Research Institute (HABRI) and Bayer Animal Health. The study was led by Maggie O’Haire, assistant professor of human-animal interaction, with the help of K9s For Warriors, an accredited non-profit organization that provides veterans with service dogs. The pilot research project provides scientific evidence of mental health benefits experienced by veterans with PTSD who have service dogs. “We found that the group of veterans with service dogs had significantly lower levels of PTSD symptomology than those who did not have a service dog,” O’Haire says. “They also had lower levels of depression, lower anxiety and increased social participation, meaning a willingness to leave their house and go engage with society in different activities.” The study is published in the February issue of the Journal of Consulting and Clinical Psychology. Participants were recruited between November 2015 and February 2016 from a national sample of 304 individuals who applied and were approved to receive a trained PTSD service dog from K9s For Warriors. Of these, 141 individuals chose to participate in the preliminary trial. Approximately half of the sample of participants were on the waitlist to receive a service dog and the other half already had a service dog. Measurements of various aspects of PTSD symptoms, quality of life, social functioning and work were analyzed and compared between the two groups. Results reveal that veterans suffering from PTSD exhibited better mental health and well-being on several measures if they had a service dog, including: Lower overall symptoms of post-traumatic stress Lower levels of depression Higher levels of life satisfaction Higher overall psychological well-being Lower...

The Human Animal Bond Research Initiative (HABRI) Foundation today announced it has awarded a $6,000 grant to The University of Texas Health Science Center at Houston (UTHealth) School of Nursing for a pilot research study, Biobehavioral Effects of Therapy Dog Visitation in Elderly Intensive Care Unit Patients, to investigate how brief visits from therapy dogs can reduce stress in older intensive care unit (ICU) patients. “Elderly patients who are admitted to the intensive care unit are at risk for anxiety that negatively affects physical health,” said primary researcher Sandra Branson, PhD, MSN, RN, Assistant Professor at the UTHealth School of Nursing. “Limited evidence suggests the effectiveness of therapy dog visits in improving these biological responses. We’re hoping this study will help fill the gap and potentially translate into regular practice in ICUs.” Further exploring the effects of therapy dogs on stress in elderly ICU patients, the study aims to provide research-based evidence proving the efficacy of brief, 10-minute therapy dog visits in improving stress associated with being in an ICU. The 18-month study will observe two groups of 10 elderly participants in the ICU; one group will receive a 10-minute therapy dog visits at random and the other will receive usual care without the visits. Patients’ psychosocial, endocrine, and inflammatory responses will be measured immediately before and after the 10-minute care session and compared between the two groups. It is predicted that participants who receive the therapy dog visits will show greater reductions in the measured responses. The results of this study could yield therapy dog visits as a regular, low-risk and low-cost treatment intervention for patients in the ICU. “HABRI’s grant to UTHealth will help advance the science that demonstrates the benefits of companion animals for disease recovery and healthy aging,” said HABRI Executive Director Steven Feldman. “The deployment of therapy...

The Human Animal Bond Research Initiative (HABRI) announced today it has awarded a $44,000 grant to Duke University School of Medicine’s Division of Pediatric Cardiology for a new research study titled Impact of Animal Assisted Therapy on Quality, Completeness, and Patient and Parental Satisfaction in Children Undergoing Clinical Echocardiography. This study will examine the influence of Animal-Assisted Therapy (AAT) on young children undergoing an echocardiogram. It is hypothesized that children will have a more complete and higher quality echocardiogram in the presence of therapy dogs. In addition, parents are expected to report higher visit satisfaction scores and greater exam comfort for their children. “Echocardiography is an effective way to use ultrasound to ‘see’ inside the heart, and while taking the pictures is non-invasive, it can still be a scary procedure for young children,” said the study’s principal investigator, Dr. Piers C.A. Barker, Division of Pediatric Cardiology, Duke University School of Medicine. “Typically, we must sedate children who have trouble holding still so that we can get adequate pictures. This study aims to evaluate whether animal-assisted therapy could serve as an effective alternative technique to comfort the children and put them at ease, potentially resulting in more complete echocardiograms, higher quality images, and avoidance of sedation drugs.” “We know from previous scientific research that animal-assisted therapy is effective in alleviating anxiety in hospital patients,” said co-investigator, Margaret Gruen, DVM, PhD, DACVB of Duke. “This is one of the first studies to focus on the potential of animal-assisted therapy to impact a clinical outcome. If results are successful, this study could potentially add non-pharmacologic, low-cost options to improve diagnostic quality for children having medical imaging procedures and could encourage broader use of therapy dogs in other pediatric cardiology settings.” The...
