ABSTRACT. Purpose: Successful physical functioning is thought to have a positive influence on the perception of physical competence. How people perceive their physical competence may act as an important mediator between the capacities they have and their behavioral performance, thereby influencing autonomous functioning. The presentation will focus on the association between physical activity and perceived competence and possible impact of chronic disease and pain. Methods: Interview and questionnaire data were obtained from 3107 subjects between 55 and 85 years of age as part of the Longitudinal Aging Study Amsterdam (LASA). Results: Perceived competence and physical activity are positively associated, while a gradual decrease on both factors is shown as age increases. Furthermore, women systematically perceive their physical competence as weaker than men. Furthermore, both perceived competence and physical activity are negatively influenced by chronic disease and pain, although a few exceptions are noted. Conclusion: Perceived physical competence and physical activity are positively associated, while chronic disease and pa in have a negative impact on the interrelationship.
