Research Scientist in Biostatistics
Biography
Dr. Calvocoressi is best known for her work in obsessive-compulsive disorder. She conducted pioneering work in understanding the role of the family in OCD and developed the original Family Accommodation Scale. There are now several versions of the scale, which have been translated into multiple languages and are used worldwide in research and clinical practice. The scale examines the ways in which relatives may participate in OCD behaviors along with the diagnosed family member or may modify their work or social functioning to accommodate the OCD. Dr. Calvocoressi is currently overseeing a large psychometric study of the self-rated version of the scale. She and her colleagues are also developing a measure to examine relatives' motivations for engaging in accommodating behaviors.
Dr. Calvocoressi oversees the MS program in biostatistics; she co-teaches the graduate biostatistics capstone course, Statistical Practice; and, she is the director of the Young Scholars Program and Internship in Biostatistics and Clinical Research, a program for gifted and talented high school students.
