The Efficiency of Communication Skills Training on

The aim of this study is to determine the effect of communication skills training on increasing self-differentiation among high school boy students. This study was an experimental project by using a pre-test post-test design with control group. The sample consists of 30 high school boy students who were selected by using a multistage sampling method and then based on the scores achieved from the differentiation of self inventory (DSI)، 30 students were randomly assigned to experimental and control groups. Students in the experimental group were given 12 sessions of group communication skills training. While the control group received no intervention، both groups were post-tested after 10 days of the last session. Obtained data from self-differentiation inventory was analyzed through the comparison and analysis of covariance. The Findings of the study have shown that group counseling based on communication skills training has increased boy students self-differentiation (p<0/001). Besides، the students in experimental group have shown a considerable degree of increase in all four dimensions of self-differentiation. Communication skills training lead to increasing self-differentiation in high school boy students.
