The effectiveness of emotion regulation therapy on improvement of shame and guilt emotion and co-rumination in adolescents with self-harm

The present study was conducted with the aim of investigating the effectiveness of emotion regulation therapy on the improvement of shame and guilt emotion and co-rumination in adolescents with self-harm. The research method was semi-experimental with a pre-test-post-test design and a control group. The statistical population of the research included all male teenagers in the age range of 13-18 years in Ardabil city in the second half of 2022. The number of the research sample was 30 people, who were selected by purposive sampling and randomly replaced in 2 groups (emotion regulation treatment, 15 people, and the control group, 15 people). To collect data, the Shame and Guilt Readiness Scale (Gasp) (Cohen et al., 2011), the Beck Suicide Scale Ideation (BSSI) (Beck, 1979), and the Co-Rumination Questionnaire (CRQ) (Rose, 2002) were used. Eight 75-minute sessions of emotion regulation training were provided for the experimental group. Data analysis was done by multivariate covariance analysis test. The findings showed that by controlling the effect of the pre-test, there was a significant difference between the average of the post-test emotion of shame and guilt and common rumination in the two experimental and control groups at the level of 0.01. The obtained results indicated the effectiveness of emotion regulation treatment in improving feelings of shame and guilt and common rumination in adolescents with self-mutilation.
