Host Society

The International Society of Behavioral Medicine (ISBM) is intended to serve the needs of all health‑related disciplines concerned with the integration of psychosocial behavioral and biomedical sciences. The ISBM will promote effective international communication between both individuals and national groups to facilitate research, clinical and training activities on a worldwide basis. The ISBM will endeavor to overcome the uneven distribution of scientific and clinical information and the formidable barriers that exist to timely access to existing information sources in most parts of the world. The ISBM will make efforts to establish a world‑wide communication system for technology transfer and information dissemination which will keep pace with this rapidly developing field.

Anne H. Berman, Ph.D.
President ISBM

Anne H. Berman, Ph.D., is a Professor of Psychology at Uppsala University, and the current President of the International Society of Behavioral Medicine. She is a clinical psychologist, with a research focus on assessment and low-threshold digital treatment of addiction and mental health issues within a behavioral medicine perspective.

Her overall research goal is to reduce the treatment gap which arises when people with signs and symptoms of problematic addictive behaviors, as well as mental health issues, remain unaware of their inner experiences as problems that can be assessed and treated, and do not seek help. Based at Uppsala University and Karolinska Institutet, her research focuses on digital interventions for problematic substance use and for university students with mental health issues. She has authored over 100 publications, including over 100 peer-review articles, 4 books, 11 book chapters as well as over 20 scientific reports. Clinically, she worked as a psychotherapist in addictions for 10 years, followed by four years as director of the Swedish National Helpline for problem gamblers and their family members. Within her longstanding interest in behavioral medicine, she has produced a Massive Online Open Course (MOOC) on behavioral medicine, KIBEHMEDx, now available without cost on Canvas after an initial launch on edX. She received a Distinguished Career Contribution Award in Behavioral Medicine in 2018.

For the past 25 years his research has focused on exploring psychosocial issues among prostate, bladder, and breast cancer patients. This has included the assessment of cognitive and affective factors in reaction to disease and treatment, their influence on treatment decision making, and the exploration of general and disease specific quality of life. Guided by a self-regulation theoretical framework, his research has alternated between the assessment of basic psychological phenomena and the development of applied interventions based on basic findings. His research has been continuously funded by the NCI, the Department of Defense, and the American Cancer Society.  Dr. Diefenbach has a long history of service to the behavioral medicine and academic community.  He has served on NIH study sections and was the senior associate editor of Translational Behavioral Medicine.  He is the primary author of the recently published Handbook of Health Decision Science and for the Society of Behavioral Medicine has been its treasurer/secretary and President.

… such as parenthood and early family development. Dr. Rhodes is also one of the world experts on the intention-behavior gap, made popular by New Years resolutions that people struggle to enact every year. His team has created a theoretical model, known as multi-process action control that has been validated with success to assist in turning good intentions into sustainable behavior change through habit and identity formation. Dr. Rhodes has held over 120 grants for this research and he has contributed over 450 publications, 35 book chapters and three books.
