The purpose of this study is to test a hypothesis that the relationship intensity between personal constructs is stable in comparison to interpersonal perception. Role Construct Rep Test (Split-Half Form) was given to 337 university students twice with an interval of 2 months. The relationship intensities between personal constructs were highly stable between situations in comparison to interpersonal perceptions. Moreover, one index of the relationship intensities between constructs revealed a high intra-individual stability of the relative position of each construct in a construct system. Another index revealed a high inter-individual stability of the retative position of each individual in his group.
