Research Interests

Jack Nassau's research focuses on the psychological influences on pediatric chronic medical illness. He is particularly interested in the effect of stress on immune function in children and adolescents with chronic medical conditions such as asthma and inflammatory bowel disease, and in the effectiveness of multidisciplinary family therapy on the psychological and health outcomes of children and adolescents with functional pain complaints.

Currently, he has National Institutes of Health funding to study the effect of stress on immune system mediators of airway inflammation in adolescents with asthma. The study investigates whether among some adolescents with asthma, psychosocial stress induces a shift in immunity that supports inflammatory processes in the lungs, and whether the degree of immune change is associated with the degree of stress experienced by the subject. Another study examines the effect of stress on immune mediators of intestinal inflammation in adolescents with Crohn's disease to explore whether the immune response to stress is similar in people who have different immune-mediated diseases or whether the immunological characteristics of the disease play a role in how stress influences the immune system.

Other active areas of interest include evaluating the quality of life, family functioning, and psychosocial functioning of children and adolescents with a variety of illnesses (such as diabetes and functional pain syndromes) who have been referred for treatment in the Hasbro Children's Partial Hospital Program. The goal is to show that children and adolescents with a variety of illnesses can benefit from a common family-based treatment.
