The subjects of this study were 342 students of the Walisongo State Islamic University of Semarang, who were selected using the cluster random sampling technique. Data were collected using three psychological scales, namely self-concept scale, self-efficacy, and effective interpersonal communication scale. Simple regression techniques and multiple regressions were used for analyzing the data.

In line with the finding, self-efficacy also has a contribution to it by 12%. Also, self-concept and self-efficacy simultaneously had contributions to the effectiveness of the students' interpersonal communication as much as 12.2%.
