The finding suggested that metagcognitive strategies for developing reading comprehension and working memory are more effective for students with dyslexia. Metacognitive strategies in reading comprehension and working memory in accuracy are more effective.

This study examined the effectiveness of cognitive-behavioral therapy on social anxiety and blood sugar control in children with type I diabetes Mellitus. For this purpose, 38 children affected by diabetes Mellitus type 1, living in Tehran, were selected randomly and were divided into the experiment group (n = 19) and control group (n = 19). In this investigation, clinical trial method of pre-test and post-test types with control group was used. The measuring tools included the Children Symptom Inventory, Parent Form (CSI-4) and HbA1C test, which were used before and after the treatment. Then, in order to investigate the experimental group, 12 sessions of 45 minutes cognitive-behavioral therapy were conducted. For analyzing the data, a univariate and a multivariate covariance analysis were used. The results showed a significant difference between the experiment group and control group in terms of the effectiveness of cognitive–behavioral therapy on the variables under study. As such, cognitive–behavioral therapy reduced the social anxiety and improved the blood glycemic control in the group which received cognitive–behavioral therapy, relative to the control group. The results of the investigation also showed that, along with other available treatments, the cognitive-behavioral therapy can be considered as one of the new effective remedial intervention, especially in children affected by diabetes.

The population of the present study includes all B.Sc students of Mohaghegh Ardabili University, among them three hundred and seventy-five students (175 female and 200 male)were selected, using proportion-stratified random sampling method. They were asked to respond to self-disclosure (attitudes, interests, study, money, personality and body) and Dark Triad Personality (Narcissism, Machiavellism and Psychopath) Questionnaire.The collected data were analyzed using Pearson correlation and stepwise multiple regression.The results of Pearson correlation showed that there were positive correlations of machiavelism with subscales of study/work, personality, body and total self-disclosure, and psychopath with subscales of body and total self-disclosure. Finally the results showed that there were positive correlations of narcissism with subscales of interest and study/work, personality, body and total self-disclosure. The results of stepwise multiple regression analyses showed that among three dark personality traits, two personality traits, narcissism and machiavellism,were predictors of online self-disclosure. According to the results of the present study, the role of two dark triad personalities, narcissism and machiavellism, on internet self-disclosure was confirmed. This result can help internet users, especially students, to discover interests and personality characteristics of individuals with high internet self-disclosure in cyber atmosphere and increase knowledge and predict exploitation of these people.
