Computer-Tailored Decision Support Intervention to Enhance Shared Decision-Making in Lung Cancer Screening

I am a behavioral scientist with over a decade of clinical experience as an adult nurse practitioner, which greatly informs the lens through which I view my research. My evidence-based program of research is focused on understanding the many factors that influence the decision-making process in lung cancer screening decisions as well as actual lung cancer screening behavior. I have a particular passion for understanding how stigma influences lung cancer screening behavior that is informed by my earlier work exploring lung cancer stigma and its influence on delayed medical help-seeking behavior in lung cancer patients. My overarching goal is to develop and translate science in this emerging field of lung cancer screening to improve the decision-making process and decisional outcomes in patients at risk for the deadliest cancer in the world. To date, I have developed a conceptual model on lung cancer screening participation to guide research in this area as well as developed and psychometrically validated the Lung Cancer Screening Health Beliefs Scales (comprised of four scales to measure perceived risk of lung cancer, perceived benefits of lung cancer screening, perceived barriers to lung cancer screening, and self-efficacy for lung cancer screening). I have examined knowledge and beliefs about lung cancer and screening in long-term smokers as well as explored the decision to opt out of lung cancer screening in patients who were recently offered screening by their primary care provider and declined. My current work is focused on enhancing the shared decision-making process in lung cancer screening. I am currently leading a mixed methods study funded by the National Cancer Institute (R15 CA208543-01A1) testing our conceptual model on lung cancer screening participation. I have also developed a theory-based computer-tailored decision support intervention called LungTalk funded by an IUPUI DRIVE grant, IU Simon Cancer Center American Cancer Society Institutional Research Grant, and IU School of Nursing Pilot Grant. The purpose of LungTalk is to help prepare high-risk patients to engage in a discussion about lung health and screening with their healthcare provider, make a decision about lung cancer screening, and intervene with current smokers to move them forward in stage of readiness for smoking cessation. LungTalk is being designed for multiple uses including pre-visit either deployed via email through a patient portal or on a tablet in an exam room while a patient waits to see their provider, during the clinic visit, and post-visit for continued support for patients who remain undecided. LungTalk is also being designed for rapid dissemination, implementation, and translation into clinical practice.
