Effectiveness of Cognitive-Behavioral Therapy Based on Suicide Prevention (CBT-SP) On The Cognitive Flexibility and Self-Criticism Among Adolescent Boys with a History of Suicide Attempt

The increasing rate of suicide among teenagers is considered an important issue at the global health level. The aim of this research is to investigate the effectiveness of cognitive-behavioral therapy. The research methodology was a semi-experimental pre-test-post-test design with experimental and control groups. The socio-statistics of this research were all male students aged 15 to 18 who had a history of suicidal activity who studied in the Tabadakan district of Mashhad in the academic year of 1401-1402, out of which 40 people were obtained as a sample and in two groups were tested. They were controlled. The experimental group received treatment (CBT-SP) for 12 sessions of 60 minutes in a group and one-session weeks; the control group was placed on the waiting list. Using the data collected using the inferred (CFI) of Dennis and Vanderwaal (2010) and the identified self-criticism (LOSC) of Thomson and Zaroff (2004), their reliability was determined using the Cronbach's alpha coefficient of 0.81 and 0.82 respectively. Analysis of covariance was analyzed. The results of CBT-SP show a significant increase in cognitive acceptance scores, controllability perception components, behavior justification perception, various choices to reduce and become self-critical, internal self-criticism, and external self-criticism. Given that cognitive-behavioral therapy for suicide prevention (CBT-SP) has been shown to improve student recovery in students with self-motivated abilities, this treatment can help as a clinical intervention to reduce suicidal behaviors.
