A self-rated health score indicates an individual's perception of his or her own state of health. Feeling healthy is important, so self-rated health scores are taken seriously in the medical field, but there are no instruments that can be used explicitly to measure self-rated health. The present study used the MT-system to create a scale based on a database including controllable factors, with which self-rated health was improved. Scores of 5 points out of a maximum of 10 were raised to 7 by an identifiable combination of factorial effects. These findings may contribute to the evolving methods of measuring changes in self-rated health when a person changes his or her own behavioral pattern.
