Aim and Background: Obsessive-compulsive disorder is one of common disabling disorders in adolescents. Many factors contribute to the emergence and maintenance of this disorder, among which cognitive constructs have recently attracted much attention. Therefore, the present study was aimed to predict obsessive-compulsive disorder in middle school students based on the components of mindfulness, cognitive emotion regulation strategies and coping strategies.
Methods and Materials: This study was descriptive and correlative study. The statistical population consisted of all middle school students in city of Tabriz in academic year of 1397-98. Finally, data of 357 students (200 girls and 157 boys) who had been selected as research sample through multistage cluster sampling method, were analyzed. The research data were collected by Obsessive–Compulsive Inventory-Revised (OCI-R, Foa et al. 2002), Kentucky Inventory of Mindfulness Skills (KIMS), the short 18-item version of Garnefski and Kraaij’s Cognitive Emotion Regulation Questionnaire (CERQ-short) and Endler & Parker's Coping Inventory for Stressful Situations (CISS). The collected data were analyzed using Pearson correlation coefficient and stepwise multiple regression analysis.
Findings: The findings showed that self-blame of cognitive emotion regulation strategies (r=0.159, p<0.01) and avoidance-oriented of coping strategies (r=0.058, p<0.01) have a significant positive relationship with obsessive-compulsive disorder. Acceptance without judgment (r=-0.151, p<0.01) and description (r=-0.103, p<0.01) of mindfulness components and task-oriented coping style (r=-0.073, p<0.01) have a significant negative relationship with obsessive-compulsive disorder. Finally, self-blame and Acceptance without judgment were able to explain 3.9 percent of the variance of obsessive-compulsive disorder in two steps.
Conclusions: Considering these results, for preventing adolescents ‘obsessive-compulsive disorder, paying attention to self-blame and acceptance without judgment variables is so necessary.

Aim and Background: Coronavirus disease 2019 is a contagious disease caused by a virus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The prevalence of this Virus has had a variety of effects on different people in the community, with some people exhibiting a higher rate of self-care behaviors that can point to a variety of reasons. The aim of this study was to investigate the role of Health Locus of Control and Death Anxiety in predicting self-care behaviors related to the COVID-19 in the student population of Tehran.
Methods and Materials: The present study was descriptive-correlation with predictive method. The statistical population of the present study was all students in Tehran in the academic year 1401-1400. Among them, 478 people were selected for the research sample by available sampling method and evaluated online with the Multiple Health Locus of Control scale (1978) and Death Anxiety scale (1970) through the social networks. Then, the obtained data were analyzed by Pearson correlation and stepwise regression via statistical package for social sciences version 26.
Findings: The results showed that there are positive and significant relationship between internal locus of control, locus of control related to powerful others and death anxiety with self-care behaviors (p<0.01) and there is a negative and significant relationship (p<0.05) between locus of control related to chance and self-care behaviors. Also, the results of stepwise regression analysis showed that research variables can only explain and predict 14% of the variance of the self-care behaviors of students in Tehran.
Conclusions: In general, the findings of this study confirmed the more prominent role of the locus of control related to powerful others in predicting self-care behaviors related to the COVID-19 in students.
