Outcome expectations that motivate physical activity among world senior games participants.

This study validates a questionnaire which examines the role of selected outcome expectations from physical activity on motivating regular physical activity among a group of older adults. Data were obtained from a cross-sectional survey of 675 participants in the 2002 World Senior Games. Factor analysis identified four clusters among 14 outcome expectation items, which were labeled Recreation and Social, Physical Health, Mental Health, and Self-image. The percentage agreeing that the selected items motivated physical activity were calculated and ranked from 1 (high) to 14 (low). The average ranking in each of the four factors was 4.7 for Recreation and Social, 5.8 for Physical Health, 10.5 for Self-image, and 11.7 for Mental Health. The ranks of items did not significantly differ across categories of sex, age, marital status, education, smoking, alcohol drinking, and disease history. However, the ranking did significantly differ between individuals who considered themselves to be physically active versus sedentary. Physically active individuals were most likely to agree that recreational enjoyment or fun motivated physical activity, whereas sedentary individuals were most likely to agree that improving the quality of life motivated physical activity.
