The effectiveness of acceptance and commitment therapy on impulsivity and co-rumination in students with suicidal thoughts

The purpose of this study was to determine the effectiveness of acceptance and commitment therapy on impulsivity and co-rumination in students with suicidal thoughts. The research method was semi-experimental with a pre-test and post-test design with a control group. The statistical population included all the students of Ardabil Islamic Azad University in the academic year of 2022-2023, of which 39 people were selected by the purposeful sampling method and randomly replaced in two experimental groups (19 people) and control groups (20 people). The experimental group underwent eight 75-minute sessions and one session per week of acceptance and commitment therapy. Data collection tools included the beck suicide scale ideation (BSSI) (Beck and Steer, 1991), the co-rumination questionnaire (CRQ) (Rose, 2002), and the Barrett impulsivity questionnaire-11 (BIS-11) (Patton et al., 1995). Data analysis was done with multivariate analysis of covariance (MANCOVA). Based on the findings, by controlling the effect of the pre-test, there is a significant difference at the level of 0.01 between the mean of the post-test of impulsivity and co-rumination (and their components) in the two experimental and control groups. Based on these findings, it can be concluded that acceptance and commitment therapy is a suitable psychotherapy method to reduce impulsivity and co-rumination in students with suicidal thoughts.
