Description of ADS Plus. Theoretical Framework - ADS Plus draws upon the Pearlin et al., stress process model and its iteration in the NIH REACH trials. These models suggest that factors such as care needs of older adults, behavioral symptoms, and/or CG health serve as primary stressors for CGs. CGs evaluate whether external demands pose potential threats to the older adult and/or themselves, and if so, whether they have sufficient coping mechanisms. If CGs perceive external demands as threatening and their coping resources as inadequate, they experience burden. The appraisal of stress is assumed to contribute to negative emotional, physiological, and behavioral responses that place CGs at risk for poor health, diminished wellbeing and depression.
