Description

<p>  BACKGROUND: There are high expectations in Europe and the United States on the effects of computer-based intervention programs as a population approach method aimed at increasing the amount of physical activity based on the behavioral change theory. However, very few researches are conducted in Japan to develop and validate the impact of such programs. PURPOSE: To develop and use a computer walking program (CWP) aimed at increasing the amount of lifestyle physical activity based on the behavioral change theory, and to objectively assess its validity by observing changes in the step count as preliminary study. METHODS: The study was conducted on 32 employees at Company O (16 men, 16 women) for a 10-week period. A pedometer was distributed to each participant. Participants were randomly assigned to one of three intervention group: 1) Computer-based media intervention group with motivationally-tailored individualized feedback and behavior change techniques, 2) Printed-based booklet intervention group with behavior change techniques or 3) Control group provided with health-related information. CWP Group had their pedometer data automatically retrieved onto My Page of CWP every week, checked step count, and set their following week’s target. Tips on actions to increase the step count were provided. RESULTS: 20 out of 32 original participants were completed the program (Analysis objects were the participants who completed the program). There was a significant difference in the step count during intervention period between CWP Group and Control Group (F2,17 = 7.095, p < .05). CONCLUSION: The findings indicate that the CWP can be regarded as a promising population approach method.</p>
