Presidential Address: Team Science Across Disciplines: Advancing CBT Research and Practice on Hoarding.

This presidential address focuses on the recent history of research and practice on hoarding disorder (HD) as a potential model for coordinating interdisciplinary teams of professionals within and outside mental health fields to advance scientific efforts to understand and resolve mental health problems. To identify, assess, and intervene with clients who have HD, psychologists, social workers, psychiatrists, and other service professionals are needed, including those in public health, housing, medicine, aging and protective services, fire, safety, and animal protection. Research findings and practice methods developed by many of my colleagues highlight the various skills of these diverse disciplines and fields. Of particular interest are multimethod assessments and CBT interventions that span individual, group, and family treatments, delivered in the office, at home and via the web by mental health and other professionals, as well as peers. Outcomes are positive, but there remains much work to do to improve understanding and intervention outcomes.
