There is a growing need for geropsychologists who are specialists in practice, research, education, and advocacy for older adults. The combined USF/Tampa VA geropsychology fellowship program focuses on the training of three post-doctoral Fellows each year in public sector service delivery across diverse long term care (LTC) and primary care settings. Addressing the bio-psycho-social needs of frail, poor, and minority older adults within an interdisciplinary framework exposes geropsychology Fellows to the complex nature of mental health problems of older adults and the need for collaborative efforts across professional lines. The program builds on prior geropsychology training at the graduate and internship levels by providing an integrated framework to achieve clinical, didactic, program evaluation, and advocacy goals: (1) delivery of state-of-the-art evidence-based psychological services to disadvantaged older adults in geriatric public sector primary care sites; (2) mastery of the knowledge base on diversity and interdisciplinary teamwork as they relate to providing services to older adults, including those residing in rural areas; (3) gaining competence in the evaluation of services to disadvantaged older adults; and (4) experience in public health advocacy for improvement of the LTC system.
