Jason Fletcher, PhD, is a psychometrician and biostatistician with more than 20 years of experience teaching, mentoring, and collaborating in health sciences research. As Director of the Biostatistics Core and Senior Research Scientist at the NYU Rory Meyers College of Nursing, he built the college’s centralized statistical support, collaborates with faculty on their research, and mentors early-stage investigators and PhD students. Dr. Fletcher has taught graduate and undergraduate courses in statistics, research methods, psychometrics, and data analysis at Fordham University and Albert Einstein College of Medicine, and has guided doctoral and master’s candidates through dissertation analysis and publication. 

His methodological expertise centers on the development and validation of assessment tools, psychometric analysis and scale development, and the application of advanced statistical methods in healthcare research. This collaborative work has produced more than 130 peer-reviewed publications. In healthcare quality and patient safety, he has examined nurse staffing, work environments, and quality improvement as they affect patient outcomes and care delivery. His clinical research spans diabetes management and glucose monitoring, cardiovascular health interventions, HIV/AIDS care and medication adherence, mental health outcomes, and lymphedema and chronic pain management. In nursing education and practice, Dr. Fletcher has studied nurse career trajectories, evidence-based practice implementation, healthcare technology integration, and interprofessional education models. Across all of this work, he is committed to making rigorous quantitative methods accessible to clinicians, students, and early-career researchers.

Classifying Continuous Glucose Monitoring Documents From Electronic Health Records

Zheng, Y., Iturrate, E., Li, L., Wu, B., Small, W. R., Zweig, S., Fletcher, J., Chen, Z., Johnson, S. B., & Fletcher, J. (2025). In Journal of diabetes science and technology (p. 19322968251324535).
Abstract
Abstract
Clinical use of continuous glucose monitoring (CGM) is increasing storage of CGM-related documents in electronic health records (EHR); however, the standardization of CGM storage is lacking. We aimed to evaluate the sensitivity and specificity of CGM Ambulatory Glucose Profile (AGP) classification criteria.

Concurrent Validity of a Physical Activity Vital Sign Used in an Adult Preventive Cardiology Clinic

McCarthy, M., Fletcher, J., Melkus, G., Vorderstrasse, A., Chehade, M., Katz, S., & Fletcher, J. (2025). In Nursing research.
Abstract
Abstract
In clinical settings, counseling patients on physical activity starts by assessing patients' current physical activity levels. Self-report measures of PA are generally easy to administer; however, they may be too long to be convenient and are known to correlate poorly with objective measures of physical activity.

Heterogeneous depressive symptom trajectories among women with type 2 diabetes: findings from the Women's Interagency HIV Study

Perez, N. B. B., D’Eramo Melkus, G., Fletcher, J., Allen-Watts, K., Jones, D. L., Collins, L. F., Ramirez, C., Long, A., Cohen, M. H., Merenstein, D., Wilson, T. E., Sharma, A., Aouizerat, B., & Fletcher, J. (2025). In Annals of behavioral medicine : a publication of the Society of Behavioral Medicine (Vols. 59, Issue 1).
Abstract
Abstract
Depression affects 33% of women with type 2 diabetes (T2D) and leads to increased risks of premature mortality. Fluctuation and variation of depressive presentations can hinder clinical identification.

Abstract
Abstract
The purpose of study was to explore family caregiver perspectives on work-life balance while caring for adults with Parkinson's disease.

Abstract
Abstract
Cesarean birth increases risk of maternal morbidity and mortality.

Developing and testing a web-based platform for antiretroviral therapy (ART) adherence support among adolescents and young adults (AYA) living with HIV

Abstract
Abstract
Describe the development and testing of a web-based platform for antiretroviral treatment (ART) adherence support among HIV+ adolescents and young adults (AYA) in a randomized controlled trial (RCT).

Factors Associated With the Cardiovascular Health of Black and Latino Adults With Type 2 Diabetes

McCarthy, M. M., Fletcher, J., Wright, F., Del Giudice, I., Wong, A., Aouizerat, B. E., Vaughan Dickson, V., Melkus, G. D. D., & Fletcher, J. (2024). In Biological research for nursing (Vols. 26, Issues 3, pp. 438-448).
Abstract
Abstract
The purpose of this study was to assess the levels of cardiovascular health (CVH) of Black and Latino adults with type 2 diabetes (T2D) and examine the association of individual and microsystem level factors with their CVH score.

A Pilot Study Toward Development of the Digital Literacy, Usability, and Acceptability of Technology Instrument for Healthcare

Groom, L. L., Feldthouse, D., Robertiello, G., Fletcher, J., Squires, A., & Fletcher, J. (2024). In Computers, informatics, nursing : CIN (Vols. 42, Issues 12, pp. 879-888).
Abstract
Abstract
Electronic health record proficiency is critical for health professionals to deliver and document patient care. There is scarce research on this topic within undergraduate nursing student populations. The purpose of this study is to describe the psychometric evaluation of the Digital Literacy, Usability, and Acceptability of Technology Instrument for Healthcare. A cross-sectional pilot study for psychometric evaluation of the instrument was conducted using data collected through an emailed survey. Exploratory factor analysis, inter-item and adjusted item-total correlations, and Cronbach's α calculated subscale reliability. A total of 297 nursing students completed the survey. A seven-factor structure best fit the data: technology use-engagement, technology use-confidence, technology use-history, electronic health record-ease of use, electronic health record-comparability, and electronic health record-burden. Cronbach's α indicated good to very good internal consistency ( α = .68 to .89). The instrument effectively measured digital literacy, acceptance, and usability of an electronic health record and may be implemented with good to very good reliability across varied healthcare simulation and training experiences.

Sleep Quality Mediates the Relationship Between Sleep Hygiene and Psychological Stress Among Adults With Multiple Cardiovascular Risk Factors

Liu, X., Li, J., Hu, J., Fletcher, J., Commodore-Mensah, Y., Himmelfarb, C. R., & Fletcher, J. (2024). In medRxiv : the preprint server for health sciences.
Abstract
Abstract
Poor sleep quality and psychological stress are interrelated and disproportionately affect adults with multiple cardiovascular disease (CVD) risk factors. Maintaining an optimal home environment and engaging in healthy bedtime behaviors are important components of sleep hygiene practices that influence sleep health and mental well-being. However, research is scarce in exploring the associations between sleep hygiene, sleep quality, and psychological stress among adults with multiple CVD risk factors.

Abstract
Abstract
Family support is important in assisting with diabetes self-management for individuals with cognitive impairment, but what types of family support are most effective remain unknown.
