Emotional dysregulation has been identified as an important meta-diagnostic factor for the etiology and treatment of various psychological problems. The present study was conducted with the aim of investigating the structural relationships of childhood trauma with positive memory and depressive symptoms with regard to the mediating role of positive emotional dysregulation in adults.

The statistical population included all people referring to clinics and psychological service centers in Tehran in 2023. Among the statistical population, 240 people were selected by available sampling method. Research tools were: Childhood Trauma Questionnaire (CTQ), Beck Depression Inventory (BDI-II), Difficulties Emotion Regulation Scale‐Positive (DERS-P), Memory Experiences Questionnaire-Short Form (MEQ-SF). For data analysis, Pearson correlation, structural equation modeling and SPSS -22 and AMOS-26 software were used.

The results showed that the research model has a good fit. The direct effect of childhood trauma on positive memory was not significant. The direct effect of childhood trauma on symptoms of depression (T = 0.80, β = 0.80, T = 13.08) and positive emotion dysregulation (T = 0.80, 16.48), and the direct effect of the positive emotion dysregulation on positive memory (40 T = 0.76, β = 0.5) and depressive symptoms (T = 2.05, β = 0.12) were significant. Also, positive emotion dysregulation had a mediating role in the relationship between childhood trauma and positive memory and depressive symptoms.

According to the findings of the present research, positive emotional dysregulation should be a target for treatment in childhood trauma victims, to prevent mood disorders and make positive memories special. Therefore, it is suggested to use treatments such as emotion regulation based treatments, memory specificity training to reduce depression symptoms and increase memory specificity in people with childhood trauma experience.

Although previous studies have shown that there is a strong relationship between childhood trauma and depression, the mediating mechanisms of this relationship have not been well studied. Therefore, the present study was conducted with the aim of investigating the structural relationships between childhood trauma experience and depressive symptoms in adults with the mediating role of dissociative experiences and attachment styles.

The research method was descriptive-correlation. The statistical population of the research was made up of all the people who referred to the clinics and psychological service centers of Tehran in 2023. Among the statistical population, 320 people were selected by convenience sampling method. The research tools were: Childhood Trauma Questionnaire, Beck Depression Inventory-II, Dissociative Experiences Scale, and Attachment Styles Questionnaire. Pearson correlation, structural equation modeling and SPSS version 23 and AMOS version 23 software were used for data analysis.

The results showed that the research model has a good fit. Direct path coefficients of childhood trauma experience (T = 0.28, β = 2.52), dissociative experiences (T = 0.27, β = 2.63), secure attachment (T = 0.27, -2.31) β=-0) and insecure attachment (T=2.21, β=0.23) were significant on depression symptoms. Also, the indirect coefficients of childhood trauma experience through dissociative experiences (p < 0.05, b = 0.52), secure (p < 0.05, b = -0.60) and insecure attachment styles (b = 0.05) p>0, b=0.39) were significant on depression symptoms. The results also showed that the research variables explained a total of 75% of the variance of depression symptoms.

These findings may provide indications for the development of measures to reduce dissociative experiences and teachings based on attachment styles to reduce depressive symptoms in adults with traumatic childhood experiences. It is suggested that trauma and depression psychotherapists pay special attention to the two components of dissociation and attachment styles in their interventions.

Impairments in emotional processing and rumination associated with a traumatic event such as cancer are important factors that may influence the development and maintenance of PTSD symptoms. Therefore, the present study was conducted with the aim of investigating the effect of memory specificity training on deficits in emotional processing and rumination in cancer patients with PTSD symptoms.

This research was of experimental type (pre-test-post-test with control group). The statistical population of this research included all patients with a definite diagnosis of cancer and PTSD symptoms who referred to hospitals and medical centers in Tehran in 1402. 30 cancer patients with PTSD symptoms were selected as a sample by available sampling and randomly replaced in two experimental (15 people) and control (15 people) groups. The experimental group underwent memory specificity training one day a week during 6 sessions of 90 minutes, but no intervention was done for the control group. Both groups (control and experimental) before and after the intervention answered the questionnaires of the emotional processing scale-revised Baker et al.'s (2010) and the rumination response scale of Nolen-Hoeksema (1991). To analyze the data, the method of multivariate analysis of covariance was used using SPSS version 28 software.

There was a significant difference between the average post-test scores of the intervention group and the control group, so that the memory specificity training significantly led to a reduction in the deficits in emotional processing and rumination in the intervention group (P<0.05).

Memory specificity training to reduce cognitive and emotional symptoms in cancer patients with PTSD symptoms is a short-term and cost-effective treatment that reduces cognitive and emotional symptoms by increasing memory specificity. Therefore, it is recommended as an effective intervention to reduce cognitive and emotional problems of cancer patients with PTSD symptoms.

Several factors may disrupt the emotional health of nurses and lead to negative coping behaviors such as the tendency to use drugs. Therefore, the present study was conducted with the aim of investigating the role of dissociative experiences, mindfulness and loneliness in predicting the tendency to use substance in nurses.

The method of this study was descriptive-correlation. The statistical population was formed by all the nurses of Tehran city in 2023. From among the statistical population, 220 nurses working in Tehran hospitals were selected as convenience sampling and answered the scale of analytical experiences, the scale of mind-awareness assessment, the questionnaire of feelings of loneliness and the scale of readiness for addiction. The collected data were analyzed using Pearson's correlation coefficient and multiple regression analysis in SPSS-24 software.

The results showed that there is a positive and significant relationship between dissociative experiences and loneliness with the tendency to use drugs (P<0.01). there is a negative and significant relationship between mindfulness and the tendency to use drugs (P<0.01). Also, the results of the multiple regression analysis revealed that 0.684 of the variance of the active tendency to use substance and 0.638 of the variance of the passive tendency to use substance in nurses is explained by dissociative experiences, mindfulness and loneliness.

The result of the research shows the significant role of analytical experiences, mindfulness and loneliness in predicting the tendency to use substance in nurses; Therefore, health care systems should focus resources on supporting the psychological and emotional health of nurses, and in this regard, special attention should be paid to the role of the components of this study in order to design effective therapeutic interventions with the aim of preventing the tendency to drug use in nurses.
