Below is a list of resources pertaining to the Progressively Lowered Stress Threshold (PLST) model. 

Developed by the late Dr. Geri Hall and Dr. Kathleen "Kitty" Buckwalter, the PLST model was designed to educate formal and informal caregivers about the progression of dementia and associated behaviors to help inform plans of care.

Honoring Geri's Legacy

Dr. Geri Hall, PhD, RN, FAAN

Geri Hall was an exceptional nurse; a master educator and communicator, a keen observer, a skilled clinician and innovator whose accomplishments and contributions to geriatric nursing vastly improved care of older adults, particularly those with dementia. Geri had the unique ability to teach at all levels: to inform full professors as well as the newest Certified Nursing Assistant, in nursing as well as other disciplines, and those practicing in a variety of acute and long-term care settings. Her writings and presentations were internationally acclaimed and she was a much sought-after presenter and consultant.

Early in Geri’s career, she was credited with the ideas that led to the development of tools and resources to inform caregivers about managing dementia with dignity. Dr. Kathleen “Kitty” Buckwalter (71BSN, 76MA), a fellow graduate and faculty emeriti of the College of Nursing, served as her program advisor and chair for both her master’s and doctoral degrees and a mentor to Geri. Together, they created the Progressively Lowered Stress Threshold Model (PLST) designed to educate formal and informal caregivers about the progression of dementia and associated behaviors to help inform plans of care.

“When her work was first coming out, this was at the beginning of the study of dementia. So really, her research was at the forefront of that,” said Kitty. “Her work is still cited and used all over the world and is as relevant today as it was when she developed it.” Kitty goes on to describe the PLST model as one of the few models nationally recognized as an evidence-based model for dementia.

According to Kitty, "I, like so many others,  learned more from Geri than I ever taught her, and was lucky to call her friend and colleague.  Although she will be missed, Geri has left a remarkable and lasting professional legacy."
