Dr. Weihs' research focuses on family processes and emotion regulation as they affect both mental health and disease progression in patients with cancer and end stage renal disease. She has written and lectured widely on family influences on medical illness. Dr. Weihs is also an experienced psychopharmacology researcher, focusing on pharmacologic interventions for anxiety and depressive disorders in children, adolescents and adults. At the Center for Family Research she collaborated on prevention studies of children of depressed parents and children in families stressed by parental unemployment. Her research includes a longitudinal study of marital quality in breast cancer patients, examining oxytocin as a mediator of the salutary effects of close personal relationship on disease progression. This was a five-year study funded by the Army Medical Research Program in Breast Cancer Research.
