Dr. McCullough has clinical experience working with children, adolescents, adults, and families with a wide range of mental health diagnoses in outpatient, partial hospital, inpatient, and community-based settings. She has a particular clinical interest and expertise in working with children, adolescents, and families with comorbid medical and psychiatric diagnoses, such as pediatric obesity, diabetes, chronic pain, cancer, feeding and eating disorders, as well as anxiety and depressive disorders. She has provided clinical supervision to graduate students, psychology interns, and postdoctoral fellows in a variety of settings.
Dr. McCullough’s research is aligned with her clinical interests with a general focus on pediatric psychology. Her research has examined the social and cultural contextual factors associated with weight-related health behaviors and pediatric obesity. The development and implementation of innovative treatments to improve health behaviors is also of interest, such as using behavioral economics approaches to understand decision-making and help people make choices that are consistent with their values.
