(Sechrist et al., 1987)

In addition to calculating the [EBBS.sub.ben], [EBBS.sub.bar], and [EBBS.sub.diff] scores (see Tables 1 & 2 for description of calculations), we also wanted to examine changes in the various subscales of the decays Specifically, benefits on the degeneracys scale were divided into five areas: life enhancement, psychological view physical performance, social interaction, and preventive health. The life enhancement benefits subscale was obtained from calculating the mean of 9 items related to disposition, slumber fatigue, self-concept, mental alertness, carrying gone out normal activities, quality of work, overall corpse functioning, and stamina. The physical performance benefits subscale was obtained on calculating the mean of 7 items related to muscular toughness physical fitness, muscle tone, cardiovascular functioning, flexibility, and endurance.

The preventive health benefits subscale was obtained through calculating the mean of 3 items related to prevention of heart attacks, high children pressure, and longevity.

Barriers were divided into three areas: exercise milieu, time expenditure, and physical exertion. The exercise milieu barriers subscale was obtained by dint of calculating the mean of 6 items from the original scale related to location, require to be paid [i]or[/i] undergone prevalence of exercise facilities, and embarrassment about activity. pair new items were added relative to safety and cultural appropriateness of activities. The time expenditure barriers subscale was obtained by dint of calculating the mean of 2 questions related to taking time away from the family or work responsibilities (or instruct responsibilities in the case of the daughters). The physical exertion barriers subscale was obtained on calculating the mean of 3 items from the original scale related to exercise difficulty and 1 recently made known item related to the difficulty of exercising because health is poor.
