Cognition and Illness Experience are Associated with Illness Knowledge Among Older Adults with Hypertension

Abstract

We investigated how cognitive abilities and illness experience relate to illness knowledge. One hundred and forty-eight community-dwelling older adults including hypertensive patients and healthy adults completed a battery that measured illness knowledge, fluid cognitive abilities, crystallized abilities, and health history. Results suggested that hypertension knowledge was primarily associated with illness duration (despite a negative relationship between illness duration and fluid ability) and crystallized ability. Also, greater illness knowledge was associated with an illness perception that may be more consistent with self-care (e.g., greater sense of control). Implications for patient education and training are discussed.
