The effect of Gestalt therapy and cognitive- behavioral therapy on assertiveness in male guidance students

This study was conducted to investigate the effectiveness of gestalt therapy and cognitive -behavioral therapy on assertiveness in middle school students. This study was a pre-post test experimental design. By cluster sampling between schools in Sharyar two schools were selected randomly. After conducting Gambrel and Rigy Questionnaire, 30 students were selected and assigned to three groups randomly. 8 sessions of gestalt therapy were implemented for one group and 8 sessions of cognitive- behavioral therapy were implemented for another group. The control group received no intervention. ANCOVA and Post hoc LSD Test were applied to analyze data. ANCOVA showed significant differences between groups. Post hoc LSD Test showed significant difference between the control group and the gestalt therapy and between the control group and cognitive -behavioral therapy group(P≤0/01), but there was no significant difference between the gestalt therapy and the cognitive- behavioral therapy group. Both gestalt therapy and cognitive- behavioral therapy had increased the assertiveness.
