Individual differences observed in health-improving behavioral change through individual support based on the transtheoretical model : Review from "The Tenshi Health and Nutrition Clinic" 2008 and 2009
The Tenshi Health and Nutrition Clinic is a health awareness and guidance course offered to local residents for the prevention and alleviation of metabolic syndrome. The clinic, which is run over eight non-consecutive days, comprises lectures and personal interviews, and aims to help participants improve health awareness and progress through the stages of behavioral change. In this study, changes in exercise behavior, stress management and resting behavior, and dietary behavior were individually assessed over a four-monthe period in participants who completed the clinic in 2008 and 2009. Scores indicative of the stage of behavioral change (behavioral change scores) were obtained from questionnaires completed by participants on days one, three, five, and seven of the clinic. On an average, the behavioral change scores for all three types of health-improving behavior were higher in the fourth questionnaire survey than in the first one, suggesting that the participants had progressed through the stages of behavioral change. However, the results of the four questionnaire surveys showed that the time-dependent changes in health-improving behavior are not linear for many participants. When the behavioral change scores of the fourth survey were compared with those of the first survey, they were higher in some participants, but lower or unchanged in others. Information obtained from individual interviews indicated that continuous effort was made to maintain an exercise routine, in particular walking, by participants who made progress in changing their behaviors. The results suggest that with regard to participants who improved their exercise behavior, the support provided was positively linked with the strong will to continue an exercise routine.
