Objective: Given that divorce is an important phenomenon with significant impacts on families, especially on children, the present study aimed to examine rumination, healthy locus of control, and emotion regulation in children of divorce and normal children.
Methods: This was a cross-sectional study. The statistical population included all students in the first grade of high school, in Tabriz City, Iran in the first semester of 2016-2017 academic year. With the help of school consultants and using a convenience sampling method, 45 children of divorce and 45 normal children were selected from this population. The Emotion Regulation Questionnaire, the Multidimensional Health Locus of Control scale, and the Ruminative Response Scale were used to collect the study data. The obtained data were analyzed using descriptive and inferential statistics, including the multivariate analysis of variance.
Results: According to the results, compared to normal children, children of divorced parents had significantly higher rumination, suppression emotion regulation, and chance and powerful others locus of control; but significantly lower reappraisal emotion regulation and internal locus of control (F1, 88=27.53, P<0.05).
Conclusion: Rumination, healthy locus of control, and emotion regulation have important role in mental health and adjustment. Because impairment in these scopes is common among children of divorce, it is suggested that the results of the present study be used in designing treatment and care programs for children of divorce.

Objective: The present study aimed at examining worry, cognitive avoidance, intolerance of uncertainty, and metacognitive beliefs, as transdiagnostic factors, in clinical samples with Generalized Anxiety Disorder (GAD) and Obsessive-Compulsive Disorder (OCD).
Methods: In total, 200 patients (66 with GAD, 74 with OCD, and 60 with comorbid GAD and OCD) were selected to participate in this study using the purposeful sampling method. The participants completed the Penn State worry questionnaire, cognitive avoidance questionnaire, intolerance of uncertainty scale, and metacognitive beliefs questionnaire.
Results: The findings showed no significant difference between patients with GAD and OCD in total scores of these constructs; however, the patients with comorbidity of GAD and OCD showed significantly higher scores in these measures (P<0.01) compared with the patients with GAD or OCD.
Conclusion: These cognitive factors are possible transdiagnostic factors shared between GAD and OCD. Moreover, they considerably increase when GAD and OCD co-occur.

Objective: One of the most common and recent highlighted psychological problems is anxiety symptoms. This study investigated the moderating role of defense mechanisms in the relationship between confrontation with existential issues (death, freedom, isolation, and meaninglessness) and anxiety.
Methods: A total of 389 students (218 men and 171 women) of Ferdowsi University of Mashhad, in the academic year 2017-2018 were randomly selected as the research sample. In this study, anxiety symptoms, death anxiety, loneliness, meaning in life, responsibility, and defense style were measured. The obtained data were analyzed using the Pearson correlation test and stepwise and hierarchical regression analysis.
Results: Mature and immature defense mechanisms moderated the prediction of anxiety symptoms by confrontation with loneliness and responsibility. Neurotic defense mechanisms moderated the prediction of anxiety symptoms by confrontation with death, anxiety, loneliness, and responsibility.
Conclusion: Defense mechanisms affect the amount of relationship between confrontation with existential issues and anxiety.
