Considering the prevalence and consequences of non-suicidal self-injury, it is necessary to identify and treat the mechanisms involved in NSSI. Mindfulness-based cognitive therapy specifically targets mechanisms thought to be involved in the initiation and maintenance of NSSI; therefore, the present study was conducted with the aim of investigating the effect of Mindfulness-based cognitive therapy on alexithymia, experiential avoidance and rumination in people with non-suicidal self-injury.

The current study was a semi-experimental type with a pre-test-post-test design with a control group. Among the people referring to the clinics and counseling centers in Tehran, 30 people who had the highest score in the non-suicidal self-injury questionnaire were selected by convenience sampling and randomly divided into two experimental groups and The control group (15 people) was replaced. The experimental group received 8 sessions of Mindfulness-based cognitive therapy, but the control group did not receive any specific intervention. The research tools were: nonsuicidal self-injury questionnaire, Toronto Alexithymia Scale, Acceptance and Action Questionnaire, Ruminative Response Scale. Data were analyzed using SPSS version 23 software and Multivariate analysis of covariance analysis method.

The results indicate the significant effect of mindfulness-based cognitive therapy in reducing alexithymia, experiential avoidance and rumination in people with non-suicidal self-injury in the post-test stage (P<0.05).

mindfulness-based cognitive therapy, by directly addressing the mechanisms involved in the initiation and maintenance of non-suicidal self-injury, offers great promise as a transdiagnostic therapy that can be a successful intervention for individuals who engage in self-injurious behaviors. Therefore, according to the obtained findings, therapists can use this intervention to reduce alexithymia, experiential avoidance and rumination in people with non-suicidal self-injury.

As one of the most important members of the health care team, nurses play a vital role in the care-treatment system. Therefore, the present study was conducted with the aim of investigating the effect of attachment styles on the symptoms of depression and emotional dysregulation with the mediation of mentalization in nurses.

The present research is a descriptive-correlation type of structural equations. The research community included all the nurses working in hospitals and medical centers in Tehran, and 220 of them were selected by available sampling method. in order to collect data, beck depression inventory-II, adult attachment inventory, reflective functioning questionnaire, and difficulties in emotion regulation Scale were used. For data analysis, Pearson correlation, structural equation modeling and SPSS version 26 and AMOS version 24 software were used.

The results of the findings show the fit of the assumed model. Also, the coefficients of the direct paths of secure attachment style (β = -0.19, T = -2.301), avoidant (β = 0.46, T = 3.39) and ambivalent (T = 0.61, 3.09) = β) was significant to depression. Direct paths of attachment style - secure (T = -0.40, β = -0.28), avoidant (T = β = 0.65, 13) and ambivalent (β = 0.52, T = 3.79) ) was significant to emotional dysregulation. Also, the analysis of research findings indicated the mediating role of mentalization in the relationship between attachment styles and symptoms of depression and emotional dysregulation.

According to the findings of the current research, mentalization has an important effect on the symptoms of depression and emotional dysregulation. Therefore, targeted interventions that are used in order to increase the capacity of mentalization, can probably have better clinical outcomes for nurses.
