In recent years, quality of life (QOL) is becoming an important concept. However, the research of QOL in the information society is very few and it is a current state to lack for information-related QOL item almost in main QOL index. Then, in this research, we developed information-related QOL index to grasp the current situation of QOL in information society and improve QOL by use of multivariate analysis. After reliability and validity of the index were verified, we considered the method of using it.
