Dr. Jonathan A. Shaffer is a licensed clinical psychologist with training in the fields of cardiovascular behavioral medicine and quantitative methodology. He is the recent recipient of an NIH Loan Repayment Grant and an American Heart Association Clinical Research Program award to examine the role of vitamin D deficiency in the association of depression and incident cardiovascular disease.
During his postdoctoral fellowship, Dr. Shaffer has helped to collect and analyze data from both randomized controlled trials (RCT) and prospective cohort studies. These projects have examined the prognostic role of and associations among quality of life, depression, and physical activity in patients with acute coronary syndromes and heart failure. Most recently, Dr. Shaffer has examined the feasibility and treatment satisfaction associated with providing telephone-delivered cognitive-behavioral therapy to patients with heart failure. He has also pursued clinical work with cardiac patients and has completed research focusing on outcomes assessment for behavioral interventions. He recently received a K23 Career Development Award application to conduct a dose-finding study and two-arm RCT of telephone-delivered Problem-Solving Therapy to improve quality of life in outpatients with heart failure.
