Pediatric psychology is a multidisciplinary field of both scientific research and clinical practice which attempts to address the psychological aspects of illness, injury, and the promotion of health behaviors in children, adolescents, and families in a pediatric health setting. Psychological issues are addressed in a developmental framework and emphasize the dynamic relationships which exist between children, their families, and the health delivery system as a whole. Common areas of study include psychosocial development, environmental factors which contribute to the development of a disorder, outcomes of children with medical conditions, treating the comorbid behavioral and emotional components of illness and injury, and promoting proper health behaviors, developmental disabilities, educating psychologists and other health professionals on the psychological aspects of pediatric conditions, and advocating for public policy that promotes children's health. Role of the pediatric psychologist The field of pediatric psychology developed to address unmet needs for psychological services in the pediatric setting and the field blends together several distinct areas in psychology (such as behavioral medicine, health psychology, developmental psychology, etc.) (Roberts, Maddux, Wurtele, & Wright, 1982 ). Pediatric psychology is an integrated field of science and practice in which the principles of psychology are applied within the environment of pediatric health. The Society of Pediatric Psychology (SPP, Division 54) resides under the American Psychological Association (APA), see http://www.apadivisions.org/division-54/index.aspx. SPP aims to promote health and psychological well-being of children, adolescents, and their families through the promotion of evidence-based science and practice, education, training, and advocacy. The field was founded in 1969 and includes a broad interdisciplinary foundation, drawing on clinical, developmental, social, cognitive, behavioral, counseling, community and school psychology. Pediatric psychologists work in a variety of settings and fulfill various roles such as (Spirito, 2003 ): (1) Providing psychosocial services for problems related to pediatric health conditions (2) Psychological services for mental health problems appearing in medical settings—which involves mental issues related to medical conditions or the treatment of them, coping related to chronic and acute illnesses, adherence, quality of life, pain, traumatic medical stress, adjustment related issues on the psycho-social continuum, school reintegration, and behavioral problems (3) Psychological services for mental health problems without concomitant health condition (4) Programs for promotion of health/prevention and early intervention (5) Provide assistance for those with intellectual and/or developmental disabilities (6) Psychological training and consultation for physicians (7) Public health and public policy. Interventions are not just illness-related, but address behavioral problems as well.
