High school and university students' relations with friends have been previously described in terms of the dimensions of depth and extent. The present study re-examined those relationships. Participants completed a questionnaire developed from the viewpoint of changeovers according to situations, which was expected to reveal a new perspective on their relations with friends. Factor analysis showed that this new viewpoint could be distinguished from the existing factor as another dimension, and that, in that context, a two-dimensional explanation using only depth and extent is not appropriate. Furthermore, multiple regression analysis revealed that the viewpoint of changeovers according to situations enabled improved adjusted Rsquared predictions of the psychological stress response. A large number of different partial correlation coefficients between before and after were obtained, adding the new factor scores as explanatory variables.
