Control Beliefs after a Diagnosis of Alzheimer's Disease and Related Dementias: The Need to Foster Resilience.

Positive adaptation, like higher control beliefs, following a disability diagnosis is important to buffer against excess disability; however, no study has examined how the recent diagnosis of Alzheimer's disease and related dementias (ADRD) impacts control beliefs. The current study addresses this gap in the literature. We use data from the 2012-2016 waves of the Health and Retirement Study. Propensity score weighting was used to address the systematic selection of an ADRD diagnosis to understand how control beliefs (perceived constraints and mastery) are impacted two years following a diagnosis. A new diagnosis of ADRD was associated with a lower mastery score two years later, regardless of baseline functional ability (b = -0.652, < .001). No associations were noted between a new ADRD diagnosis and perceived constraints. Our results suggest that a recent diagnosis of ADRD has negative implications for mastery, which may facilitate excess disability.
