The effect of rumination-focused cognitive behavior therapy on negative self-evaluation and suicidal ideation, versus mindfulness-based cognitive therapy in depressed adolescent girls aged 14 to 19 committing suicide: two-month follow up

Suicide attempt is on the rise among adolescent girls due to negative cognitions, so the aim of this study was to investigate the effect of Rumination-Focused Cognitive Behavioral Therapy (RFCBT) versus Mindfulness Based Cognitive Therapy (MBCT) on negative self-evaluation, and suicidal ideation among depressed girls adolescents aged 14 to 19 attempting suicide. This study was a quasi-experimental design with pre-test and post-test with a control group. Thirty-three depressed adolescent girls attempting suicide who were referred to the emergency department of Samen Al-Aeme and Imam Hassan Hospitals in Bojnourd from October 23, 2019 to March 5, 2020, after having the inclusion criteria, were selected with targeted sampling method, then randomly divided into three groups of rumination-focused cognitive behavioral therapy, mindfulness-based cognitive therapy (10 individual sessions) and control. The research tools included Depression Inventory-2 (Beck & Steer, 1993) and Suicide Probability Scale (Cull & Gill, 1989). Findings obtained from Analysis of covariance showed that both interventions had a significant effect on reducing negative self-evaluation and suicidal ideation at the time of post-test (p <0.001) and follow-up (p <0.05), and this effect was stable during the two-month follow-up period. Therefore, both interventions can reduce negative self-evaluation and suicidal ideation in different ways (decreased rumination and increased mindfulness) but without superiority, so it is recommended to use these two interventions in times of depression and in times of suicidal crisis.
