Ronette L Kolotkin serves as an Adjunct Professor in the Department of Family Medicine and Community Health at Duke University, where she maintains active research and consulting roles. A practicing psychologist with a Ph.D. from the University of Minnesota (1978), she is internationally recognized for developing the Impact of Weight on Quality of Life assessment suite (IWQOL-Lite, IWQOL-Lite-CT, and IWQOL-Kids) used globally in obesity research and clinical practice.

Education

• Ph.D., University of Minnesota, Twin Cities (1978)

Her research program centers on obesity-related quality-of-life measurement, with expertise spanning psychometric validation, clinical trial design, and patient-reported outcomes analysis. Dr. Kolotkin specializes in evaluating how pharmacological (e.g., semaglutide) and surgical (e.g., gastric bypass) obesity interventions impact physical functioning, mental health, and disease comorbidities. Her work bridges clinical psychology, endocrinology, and public health through collaborations with pharmaceutical companies and multinational research teams.

Analysis of her 10 most recent publications reveals consistent focus on long-term obesity treatment outcomes, with particular emphasis on bariatric surgery durability (5-7 year follow-ups), pharmacotherapy efficacy across diverse populations (including East Asian cohorts), and instrument validation for clinical trials. The research demonstrates methodological rigor through randomized controlled trials, computer-adaptive testing, and cross-cultural adaptation studies.

Dr. Kolotkin operates through Quality of Life Consulting, PLLC, providing specialized expertise to clinical trial sponsors for product development and regulatory submissions. Her consulting portfolio includes major studies like the STEP trials series and Oseberg trial, though specific grant funding details are not disclosed in available materials.

She maintains active research engagement as evidenced by the 2025 Lancet publication, with ongoing work in suicide risk mediation analysis and digital mental health assessment tools for bariatric patients.
