Abstract

OBJECTIVES:

To examine how motives discriminate 3 physical activity levels of inactive, active, and sustained maintainers.

METHODS:

Six hundred forty-five adults (M age = 63.8) completed stage-of-change and Exercise Motivations Inventory (EMI-2) scales. Exploratory factor analysis established psychometric properties of the EMI-2 suitable for older adults.

RESULTS:

Six factors emerged in the EMI-2: health and fitness, social/emotional benefits, weight management, stress management, enjoyment, and appearance. Enjoyment contributed most to differentiating activity levels. Moderators of age and gender were delineated.

CONCLUSIONS:

Intrinsic motivation and self-determined extrinsic motivation distinguish older adults' activity levels.
