The Progressively Lowered Stress Threshold Model

PLST is a conceptual model for reducing behavioral symptoms in individuals with dementia. The PLST model provides the foundation for a psychoeducational intervention that assists formal and informal caregivers in understanding behaviors and planning care for individuals with dementia. If the model is to be applied at home, at least three home visits are made in line with the listed principles. While making a diagnosis during the first home visit, a maintenance plan for the problems is created in other home visits and the caregiver is trained to implement the care plan. After the home visits, the process is carried out by providing counseling through telephone calls or face-to-face interviews when necessary.
