The Effectiveness of Group Cognitive Therapy Based on Michael Frey's Model on the Irrational Beliefs and Loneliness of Students

The present study aimed at investigating the effectiveness of group cognitive therapy based on Michael Frey's model on the irrational beliefs and loneliness of students. The research method was semi-experimental with pre-test and post-test and control group. The statistical population included all male high school students of Natanz. Of this population, 30 students were selected by random cluster sampling method and replaced in the control and experimental groups. The research tool involved two questionnaires of Factor Irrational Beliefs Test-Ahwaz and loneliness. The experimental group received 12 sessions of 90-minute about cognitive-group therapy based on Michael Frey's model. The results of covariance analysis indicated a significant difference between the performance of the two groups in the post-test in terms of irrational beliefs and loneliness. Therefore, the group therapy based on Michael Frey's model can reduce the irrational beliefs and loneliness of students by changing and correcting their inefficient and irrational beliefs and attitudes which can result in their mental health.
