Paul Krebs, PhD, is Assistant Professor in the Department of Population Health and a Clinical Psychologist at the VA New York Harbor. His research focuses on extending the reach of tobacco cessation and health behavior change strategies, especially among cancer patients and persons with a mental health diagnosis. He has received NIH and VA funding to investigate the use of technologies to facilitate behavior change. His published research examines the design and efficacy of mHealth technologies for tobacco and health interventions and meta-analyses addressing the efficacy of behavioral interventions related to cancer prevention and symptom control. Dr. Krebs completed his undergraduate training at the University of Scranton, followed by a PhD in Clinical Psychology at the University of Rhode Island, and a post-doctoral fellowship at Memorial Sloan-Kettering Cancer Center.

- Technology and Behavior Change
My most recent work and resulting publications have addressed the development of technology-based interventions for health behavior change. Modifiable behaviors, such as smoking, physical activity, and nutrition practices, are the most significant contributors to chronic disease burden. Technology offers innumerable options for addressing such modifiable risk factors at the population level. These publications discuss innovative methods for engaging at-risk populations in health behavior change. Findings support the value of using careful formative evaluation plans to ensure that interventions are acceptable for target populations. In these projects, I led development of the mixed-method evaluation plans, conducted interviews, coded data, and summarized findings for publication. Results have directly informed crucial changes to the interventions to increase their feasibility in the field.

- Improving Reach of Tobacco Cessation Services
Ensuring that smokers receive evidence-based tobacco cessation treatment remains a challenge. While rates of provider advice to quit are now high, few patients follow up with referrals for tobacco cessation treatment. Our research has examined multiple methods for improving connection to evidence-based treatment within healthcare systems including enlisting specialty providers, modifications to electronic record screening systems, and proactive outreach using EHR data. Results indicate that proactive methods are highly effective for improving rates of connection to quitting resources. In these projects I helped develop the tobacco intervention protocols, trained counselors and provided ongoing supervision.

- Quality of Life in Cancer Patients
Many patients continue to experience impairments in physical and mental well-being following cancer treatment. Specific knowledge of these conditions is needed to improve follow-up care. These publications examine multiple aspects of health among a sample of post-treatment lung cancer survivors. Findings indicate that most survivors are burdened by ongoing health symptoms, primarily pain and fatigue. In these projects, I collaborated in identifying important outcomes in this population, conducted data analyses in SAS (b-d), and summarized findings.

The number of behavioral interventions continues to grow at a rapid pace. Replication of studies is essential in the scientific process, but differing methods and samples poses a difficulty for informing generalizable knowledge. Reviews and meta-analysis serve a critical role in advancing science by summarizing available literature and by facilitating between-study analyses. This body of work examines the value of behavioral interventions for cancer prevention and symptom management. Findings support the efficacy of tailored communications to promote health behavior change and indicate the value of psychosocial treatments for reducing pain and improving interpersonal well-being following cancer treatment. Importantly, findings also highlight the value of using treatment protocols and fidelity checks in conducting clinical trials. In these studies, I collaborated with my co-authors in defining questions that needed to be addressed, conducted literature searches, coded data, and conducted all statistical analyses.
