Research Focus

As a clinical health psychologist, Dr. Bantum's research focuses on cancer survivorship. She is interested in understanding factors related to better adjustment to diagnosis and treatment, as well as longer-term survivorship. Much of her work has been conducted by implementing online interventions with the goal of positively impacting both physical and mental health. Some of Dr. Bantum's work looks to impact primary health behaviors, such as exercise, with other intervention studies focus on impacting psychosocial behaviors, such as emotion and mindfulness.

In addition to working on interventional research, Dr. Bantum is interested in better understanding what specific aspects of interventions are related to beneficial outcomes. Within this larger goal, she is currently working on a study funded by the National Cancer Institute to examine how the role of social interaction is related to both engagement in the designed intervention as well as outcomes of interest. As much of her work is conducted in an online environment, ways in which data is captured and stored allows for these comparisons, which will hopefully lend themselves to more potent interventions for cancer survivors.

Dr. Bantum is also interested in projects that have direct relevance here in Hawaii. One current project that is a collaboration with colleagues here at the University of Hawaii Cancer Center is the Hula study for breast, cervical, endometrial, and ovarian cancer survivors. This is a biobehavioral study that looks to understand the impact of culturally relevant exercise on psychological and physical indicators of health. One additional current project Dr. Bantum is leading is related to disparities in clinical trial recruitment. She is working with a number of colleagues at the University of Hawaii Cancer Center to better understand how best to promote an equal representation of people from Hawaii in clinical trials.
