The goal of the present study was to predict safety behaviors in insomnia by investigating a number of predicting variables including depression, anxiety, worry, pre- sleep arousal (cognitive and somatic arousal), dysfunctional beliefs about sleep and metacognitive beliefs in insomnia. 400 students of Tehran University of Medical Sciences participated in this study and all participants completed Depression Anxiety Stress Scales(DASS), Penn State Worry Questionnaire, Pre-Sleep Arousal Scale, Dysfunctional Beliefs and Attitudes about Sleep Scale(DBAS), Metacognitions Questionnaire-Insomnia and Sleep Related Behaviors Questionnaire. All variables were significantly correlated with safety behaviors. Stepwise multiple regression analysis suggested that metacognitive beliefs in insomnia, somatic arousal and dysfunctional beliefs about sleep predicted safety behaviors in insomnia. Depression, anxiety, worry and cognitive arousal were excluded from the predicting model. The findings underlined the significant influence that metacognitive beliefs in insomnia, somatic arousal and dysfunctional beliefs about sleep had on individuals’ behaviors. Moreover, the results suggested that metacognitive beliefs in insomnia may need to be considered an important factor in maintaining insomnia.

Background: fatigue is an unpleasant mental feeling that has also been shown to decrease physical and Mental performance. Fatigue is a very common complaint and it is important to Healthcare Experts. Aim: this study was aimed to compare the meta-cognition of people with cronic fatigue and healthy. Metods: In this study, 120 undergraduate students (60 cronic fatigue and 60 healthy) of Tabriz University were selected by multi-stage cluster sampling and screening metods. The participants filled Fatigue Impact Scale (FIS) and short form of Wells meta-cognition scale (MCQ-30). Analyzing data was performed via independent samples t test. Results: Research findings revealed no diffrences in subscales of cognitive self-consciousness and negative beliefs about thoughts concerning uncontrollability, but there were diffrences in positive beliefs about worry, lack of cognitive confidence and beliefs about the need to control thoughts, significantly. Conclusion: On the basis of results, focusing on the role of meta-cognition could be the important part of therapeutic interventions for the people with chronic fatigue syndrome.

 Intolerance of uncertainty is a kind of cognitive bias that affects how an individual receives, interprets and reacts to an uncertain situation in the emotional, cognitive and behavioral levels. The purpose of present study was to determine the various factors that influenced the intolerance of uncertainty by using the meta-analysis method and integrating the results of previous research. By using Articles in scientific journals, all the preceding studies conducted across the country during the years 2010-2017 collected and investigated. Eventually 12 eligible studies in the field of intolerance of uncertainty with acceptable methodology including sampling methods and proper statistical validity and reliability and appropriate questionnaires selected. The research tool was the meta-analysis checklist. For this purpose, the researches, which were methodologically accepted, were selected and meta-analyzed. Homogeneous assumptions and emission errors investigated. The coefficient of effect size was evaluated using CMA-2 software. results showed that metacognitive beliefs had the highest effect size, and after that, the highest effects size were related to stress, inability to take action, and negative repeated thoughts, although the effect size of behavioral inhibition and behavioral activation was not statistically significant. Therefore, attention to these variables can help to formulate and improve the therapeutic interventions related to intolerance of uncertainty.
