Young Japanese women in the action and maintenance stages of exercise behavior change exhibited significantly higher vigorous and total weekly physical activity than those in earlier stages.
Cross-Sectional (n=233)
No
The stages of exercise behavior change scale is valid for assessing vigorous and total weekly physical activity in young Japanese women, but may not be appropriate for lower intensity exercise and sitting behavior.

The purpose of this study was to examine the construct validity of the stages of exercise behavior change for low, moderate, and vigorous physical activity behavior in female Japanese university students. Participants were 193 female Japanese university students in various stages of change regarding exercise; their physical activity was estimated using the International Physical Activity Questionnaire (IPAQ) in Japanese version (the usual 7 days, short, selfadministered version). The mean age of the subjects is 19.8 years (SD=1.3, range 18 to 23). Results show that the participants classified as being in the action and maintenance stages exhibited the highest vigorous physical activity F (4/188) =65.2, p<0.01 and the total weekly physical activity F (4/188) =60.9, p<0.01. These results offer an additional support for the validity of the stages of exercise behavior change in young Japanese women based on selfreported physical activity behavior.
MATSUMOTO et al. (2018) conducted a cross-sectional in Healthy university students (n=233). Stages of exercise behavior change assessment vs. Between-stage comparison was evaluated on Vigorous physical activity (min/week) and total weekly physical activity (Mets/min/week) (η2 0.58 (vigorous), 0.56 (total), p=<0.01). Young Japanese women in the action and maintenance stages of exercise behavior change exhibited significantly higher vigorous and total weekly physical activity than those in earlier stages.
