Child Development and Behavioral Health

Delivering high quality, family-focused diagnostic and treatment services for children with psychiatric, developmental and behavioral illnesses.

The mission of the Division of Child Development and Behavioral Health is to serve our patients with the finest clinical care supported by the research and educational resources of a leading academic institution. The Division was created in September, 2005 when the Department of Pediatrics formally merged its Child Development Unit (CDU), whose pediatricians and psychologists treat developmental and behavioral disorders, with the Durham Community Guidance Clinic (CGC), where doctors and therapists have been providing psychiatric care and substance abuse treatment to Durham County children and adolescents since 1947. This joint effort continues to provide high quality diagnostic and treatment services for children and their families with psychiatric, developmental, behavioral, and substance use illnesses in cooperation with other medical care providers, school systems, and social service agencies.

The Division faculty and staff include child psychiatrists, developmental pediatricians, child psychologists, a physician assistant, child psychiatric clinical social workers and licensed substance abuse counselors. Division faculty members participate in NIH, NICHD, National Fragile X Foundation, NIDA and SAMHSA funded clinical research in the areas of suicide prevention, fragile X genetic counseling and phenotype/genotype clinical correlation studies, interventions in Down syndrome and Pompe disease, autism spectrum disorders, and effective outpatient adolescent and young adult substance use treatments. These efforts occur in collaboration with other Duke University Medical Center research groups, including the Division of Child and Family Mental Health and Developmental Neuroscience and the Division of Medical Genetics.

In few other areas of pediatrics is child advocacy so fundamental to the work done by every clinical provider in Child Development and Behavioral Health. To this end, Division faculty members have taken leadership roles in program development and service delivery systems at the local, state, and national level in professional organizations and on advisory panels focused on promoting the emotional, behavioral, intellectual, and developmental well being of youth.


The Division provides comprehensive diagnostic and treatment services for a wide range of pediatric developmental, behavioral and psychiatric illnesses, including substance abuse. Diagnostic services include:

  • comprehensive mental health and substance abuse evaluations
  • comprehensive developmental-behavioral and autism spectrum evaluations and testing
  • psychological and psycho-educational testing

The Division also provides psychiatric consultation to Duke Children’s Hospital inpatients, Duke Children’s Health Center outpatients, Durham Public Schools, and community health centers. State-of-the-art treatment services include psychopharmacological (psychotropic medication) management, cognitive-behavioral and family therapies, an intensive outpatient substance use treatment and recovery program and genetic counseling. Among the most common problems referred to Division clinicians are autism spectrum disorders, attention-deficit/hyperactivity disorder (ADHD), adjustment problems, alcohol and illicit substance abuse, anxiety, bipolar disorder, defiant behavior, depression, Down syndrome, fragile X syndrome, obsessive-compulsive disorder (OCD), posttraumatic stress disorder (PTSD), learning disorders, and psychosis. A special fragile X multidisciplinary clinic within the Division is staffed by a developmental pediatrician, a clinical child psychologist, and a genetic counselor, with access to a parent advocate for family support.

New patients from ages three to college age are accepted. Substance use treatment services are available for patients from ages 13-24. Service to families with limited income remains a priority for the Division.
