Objective-This study examines the extent to which optimism, control beliefs and motivation, and downward social comparison contribute independently to the maintenance of older adults' positive self-evaluations in a functional domain.Method-Adaptive resources/strategies and life satisfaction were measured in personal interviews with 164 community-dwelling older adults. Participants judged their physical activity compared with the average person of their age and wore an accelerometer for 24 hours. Commonality analysis was used to estimate unique versus shared effects of the resource/strategy variables on a residual measure of self-enhancement, obtained by adjusting the comparative judgments for participants' age and objectively measured physical activity.Results-Self-enhancement was positively related to life satisfaction. Perceived control and optimism had shared positive effects on self-enhancement, whereas downward social comparison had a unique positive effect. Discussion-Self-enhancement of physical activity plays a part in at least two adaptive profiles with implications for older adults' well-being and health. Keywords self-enhancement; life satisfaction; comparative judgments; physical activity; accelerometer Compared with others of your age, how physically active are you? Would you say you are more active, the same, or less active than the average person of your age? Chances are, if you answered these questions, you rated yourself above average: Most people do, when asked to compare themselves with the average person on a positive dimension, such as their relative abilities, positive features, and chances of success (Alicke & Govorun, 2005). This phenomenon, sometimes called the "better-than-average effect," has proven to be quite reliable-even in studies that have used representative samples, familiar reference groups, Please address correspondence to: Daniel S.

Accordingly, it has become known in the psychological literature as a form of self-enhancement bias, which is a broader term for the tendency shared by most people at any age to view themselves in unrealistically positive ways (Taylor & Brown, 1988;Weinstein, 1989).Physical activity is a positive dimension of potential self-evaluation for older adults. To be active at an advanced age signifies that one does not face or has managed to overcome the most commonly recognized barriers to physical activity in later life. Such age-specific barriers are found in the kinesiology literature to include pain or disability, symptoms of chronic disease, fear of injur...
