Sense of Purpose in Life and Beliefs and Knowledge of Alzheimer's Disease.

OBJECTIVE: A sense of purpose in life is associated with healthier cognitive outcomes, including lower risk of Alzheimer's Disease (ad). The present research examines whether purpose is also associated with beliefs and knowledge of ad.

METHOD: A random subsample (N = 1,187) of community-dwelling participants from the Health and Retirement Study completed a module on self-reported beliefs and knowledge of ad.

RESULTS: Purpose in life was associated with lower perceived threat of ad and greater belief that modifiable factors (e.g., physical activity) decrease risk. Associations were not moderated by experience with ad or depressive symptoms. Purpose was unrelated to beliefs that genetics or stress increase risk or knowledge of ad.

CONCLUSIONS: Individuals with a sense of purpose are less concerned about risk of developing ad and believe modifiable factors reduce risk. These beliefs may support engagement in behaviors that reduce risk and be one psychological pathway through which purpose protects against ad.
