Objectives:One of the problems that the Internet has created is a virtual addiction or addiction to the global web world causing adverse psychological behavioral effects on the users. One of the groups at higher risk for Internet addiction is teenagers, and since Internet addiction will lead to academic failure in students, evaluating it among them and its relationship with signs of mental disorders seems necessary. Therefore, the aim of this research was to study Internet addiction and its relationship with the symptoms of mental disorders. Methods:This study was descriptive and correlational design. The sample population for the present study consisted of all male and female high school students of the academic year 2013-2014 in district 5 of Tehran. Among these individuals, a sample of 400 participants was randomly selected for analysis using cluster sampling method. To collect data, Internet addiction test and Brief Symptom Inventory were used, and data were analyzed using T-Test, Pearson correlation coefficient and multiple regression analysis. Results:The results showed that there is no significant difference between prevalence of Internet addiction in male and female high school students in district 5 of Tehran. However, there is a significant positive relationship between Internet addiction variables and symptoms of mental disorders and particularly, independent variables of psychosis and anxiety from the signs of mental disorders had a profound effect on Internet addiction. Discussion: Internet addiction causes negative effects on individuals. As prevention is better than treatment and according to this study, it is necessary to take this phenomenon into consideration as a psychological problem that often involves the younger generation who are responsible for future society construction and through education in families, schools and universities, the culture of proper use of computers, in particular the Internet and its facilities should be replaced with the false methods.

Objective: In any society, attention to physical, mental, social, and cultural health status as well as spiritual interests and providing opportunities for realization of a dynamic and healthy life is considered as the guarantee for the community health in the coming years. One of the issues that troubles the mental health of some people is infertility. In this regard, this study aims to determine the effects of infertility stress, mental symptoms, and quality of life of infertile women on predicting success rate of intra-cytoplasmic sperm injection (ICSI) and in vitro fertilization (IVF) treatment. Methods:The present study employs correlational methodology. The study population comprised all women referred to Royan Infertility Institute, Tehran, Iran. The study sampling was purposeful and included 79 infertile women. Assessment tools used in this study were as follows: depression anxiety and stress scale (DASS-s), brief symptom inventory (BSI), fertility quality of life questionnaire (FertiQol), Newton infertility stress questionnaire, and demographic questionnaire. For statistical analysis, we used test correlation coefficients of data, multiple regression analysis, and logistic regression.Results: Nagelkerke squared correlation coefficient was equal to 0.253, i.e., the predictors of depression, anxiety, and stress, brief symptom, quality of life, infertility and infertility stress, all together can explain 25% of the variance of the dependent variable -success of ICSI / IVF treatment. Conclusion:When couples are waiting for the result of their treatments, infertile women start mental rumination and experience a variety of negative emotional experiences. These negative responses which entail cognitive, emotional, and behavioral aspects of individual's psychological world, suppress the healing process and are underlying factors for physical vulnerability of infertile person against psychological pressures. Subsequently, this physical vulnerability influences outcomes of assisted reproductive technology.

Background: Purpose of this study is comparing early maladaptive schemas which are active in patients suffering from obsessive-compulsive disorder and anxiety disorders together, considering recent DSM-5 changes through which OCD has been placed in a separate and new diagnostic level.Methodology: This research is a causal-comparative study. 151 persons were categorized in three groups of people suffering from OCD (50), suffering from anxiety disorders (50), and control group (51). Early diagnosis of disorders in two clinical groups were verified based on structured clinical interview for DSM (SCID-I) and Yale-Brown obsessive-compulsive scale (Y-BOCS). General health questionnaire (GHQ-28), the short versions of the Young schemas questionnaire (YSQ), and Padua inventory-Washington State University Revision (PI-WSUR) were also implemented. Findings:Findings revealed that mean scores of all schemas of those suffering from anxiety disorders, except for Self-Sacrifice, Unrelenting-Standards/Hypercriticalness, Entitlement/Grandiosity schemas, and mean scores of all early maladaptive schemas of those suffering from obsessive compulsive disorder are significantly higher than those of control group. OCD group had significantly higher scores in Emotional Deprivation, Mistrust/Abuse, and Defectiveness/Shame schemas than anxiety disorders group. Defectiveness/Shame and Vulnerability to Harm or Illness schemas can explain 38 percent of variance of obsessive compulsive symptoms. Conclusion:The dominant and specific early maladaptive schemas of OCD are Defectiveness/Shame, Mistrust/Abuse, and Emotional Deprivation Schemas. This study besides supporting the theory of early maladaptive schemas, suggests that interventions based on specific schemas can be useful methods in treatment of OCD and anxiety disorders.
