What is Pediatric Psychology?

Pediatric Psychology addresses physical, cognitive, social and emotional functioning and development as they relate to health and illness issues in children, adolescents and families. We explore the interrelationship between psychological and physical well-being of children, adolescents and families including psychosocial and developmental factors contributing to the etiology, course, treatment and outcome of pediatric conditions.

Roles of Pediatric Psychologists

  • To serve as a consultant/liaison for inpatients
  • To serve as behavioral specialists in various clinics
  • To serve as psychologists for certain outpatients


Working with the children that are staying in the hospital, we address the psychological aspects of illness and injury. This is done by helping assess patients when physicians are working with patients whose diagnoses have a psychological component, such as eating disorders and nonepileptic seizures. In addition, we help treat patients with pain and functional problems. Finally, because the well-being of everyone involved is important to helping our patients get better, we provide support to families and to treatment teams.


We are part of a multidisciplinary team within several clinics and programs associated with East Tennessee Children's Hospital, including Motivating Mealtimes; Healthy Ways; Sleep Center; Hematology/Oncology and Grow with Me. Referrals for these clinics come from a variety of places, but mostly from primary care practices throughout the region. When an outpatient therapy referral is needed, we sometimes see these patients in our own practice. We also make referrals to community agencies and private practices of PhD Psychologists and Licensed Clinical Social Workers in the East Tennessee region.


Outpatients are served in our new office in the Medical Office Building and at the Rehab Center. We currently serve a limited number of outpatients a week in MOB and at the Rehab Center. Our referrals come from specialists, primary care practices, other therapists, and directly from families. We focus primarily on working with patients with co-existing medical and psychological conditions. Common examples include patients with NAS history and adjustment problems; anxiety and functional abdominal pain; school avoidance and chronic headaches; depression and history of cancer; patients with Asperger’s and extremely picky eating; young patient with Tourette’s and anxiety. Because of our limited outpatient capacity, we accept patients who are less likely to be served in the community, including those with chronic medical conditions and those who are very young.
