Companion confidence in the balance of community-dwelling older adults: implications for physical activity promotion.

Background And Purpose: Positive social relationships may increase the intention of older adults to be physically active. In the presence of balance impairments, however, the potential influence of a familiar companion on an older adult's physical activity is not well understood. The purpose of this preliminary investigation was to explore companion confidence in the balance capability of an older adult as a potential determinant of older adult physical activity.
