Grounded in theory of planned behaviors(TPB), we developed the leisure education program to help middle-aged women become more physically active and healthy by increasing their beliefs-namely, attitude, subjective norm, and perceived personal control. To test the effectiveness of leisure education on TPB-based cognitive variables and behavioral outcomes, we assigned middle-aged women into either experimental group(n=28) or control group(n=29). Then, we provided TPB-based leisure education for

... ddle-aged women in the experimental group, while we did not provide all of it for middle-aged women in the control group. We adopted three-wave assessments (at the beginning, at the middle, and at the end) and used repeated-measure ANOVAs in order to examine the experimentally-based longitudinal effect of leisure education on TPB-based variables and its behavioral outcomes. The result showed that middle-aged women in the experimental group perceived higher level of attitude, subjective norm, and perceived personal control than those in the control group. Following the effectiveness of leisure education. middle-aged women in the control group perceived themselves as more healthy and more vitalized/energized than those in the control group. In conclusion, we found that TPB-based leisure education increased positive beliefs(attitude, subjective norm, and perceive behavioral control) about physical activity and personal health and generativity in middle-aged women.
