Health Psychologists fill a substantial gap in healthcare services for children, adolescents and young adults. Medical concerns in children can be particularly difficult to cope with and adjust to. Health psychologists have specialized training and expertise to help children and adolescents process coping and adjustment difficulties. Health Psychologists are familiar with a broad range of physical and medical conditions and their treatments, as well as common co-occurring stress, anxiety, mood and behavioral disorders. The training and treatment approach by these providers recognizes the interplay between physical and psychosocial health and well-being.
