So what I'm stressed? A qualitative study examininga caregivers' reactions to emerging biomarkers of stress.

Background: Caregivers of adults with cancer often report significant distress yet remain difficult to engage in supportive services. While the field of Psychosomatic Medicine has continued to identify important markers of physiologic stress, and demonstrated disruption in these markers in caregiver populations, no research has investigated whether biomarker information on caregivers' reaction to stress could impact their willingness to address their ongoing distress. Methods: Here, we report on a qualitative study ( Results: Analysis utilizing the framework method revealed four emerging themes. The first theme described caregivers' ability to manage stress and willingness to engage with supportive services. Second, caregivers generally accepted the biomarker data but preferred it to be presented in a specific way. The third theme demonstrated that for some, biomarker data may actually increase their subjective distress (e.g., whether or not something could be done to improve their mental state). The last theme described how biomarkers were generally received as meaningful motivators that could increase caregivers' willingness to engage with supportive services. Conclusions: In addition to the more general identified theme of CG's willingness to engage with additional support, we gained insights into caregivers' reaction to the stress biomarkers presented. Findings will set the stage for the utility of stress biomarker information and whether it influences cancer caregivers' willingness to address their distress and motivation to engage in supportive services.
