Introduction: Considering the effect of dental hygiene in people’ s general health and since facilitation of community members’ visits to dental offices results in the improvement and enhancement of the indexes of this health field, the present study was undertaken to evaluate the relationship between ANXIETY SENSITIVITY, sensory processing, brain-behavioral systems and alexithymia and ANXIETY in dental patients. Materials & Methods: This analytical study was carried out using non-random sampling technique by including 383 male and female subjects referring to dental clinics in Esfahan in 2018. Research tools consisted of ANXIETY SENSITIVITY questionnaire, questionnaire on highly sensitive subjects, inhibition scale/behavioral activation, alexithymia questionnaire and dental ANXIETY questionnaire. Data were analyzed with SPSS 22, using correlation test and multiple regression analysis. Results: The results showed that 28. 4% of changes in dental ANXIETY can be explained with ANXIETY SENSITIVITY, sensory processing SENSITIVITY and alexithymia. In addition, 26. 1% of changes in dental ANXIETY can be explained with two dimensions of ANXIETY sensitivities (fear of body concerns and fear of lack of cognitive control); and 17. 3% of changes in this variable can be explained with different aspects of sensory processing SENSITIVITY (ease of excitement, low sensory threshold and aesthetic SENSITIVITY) (p value < 0. 05). Conclusion: There were significant relationships between the three variables of ANXIETY SENSITIVITY, sensory processing SENSITIVITY and alexithymia and dental ANXIETY of all the four predictors of the study; however, there was no significant relationship between brain-behavioral systems and dental ANXIETY.

People experience different levels of ANXIETY associated with the 2019 Coronavirus 19, which may affect their lives. The present study aimed to investigate the role of health ANXIETY, ANXIETY SENSITIVITY, and somatosensory amplification in predicting of students' COVID-19 ANXIETY. The research design was descriptive and correlational. The statistical population of the study included students of Guilan University in 2020. By using available sampling method, through online calling, 200 students participated in the study. Data were collected from the Covid-19 ANXIETY Scale (Wheaton et al), Short-term health ANXIETY Measurement (Salkovskis et al), ANXIETY SENSITIVITY Index (Taylor et al), and somatosensory amplification Scale (Barsky et al). The data were analyzed using Pearson correlation tests and multiple regression analysis. The results showed that health ANXIETY, ANXIETY SENSITIVITY, and somatosensory amplification were positively and significantly correlated with COVID-19 ANXIETY. Regression results showed that these variables significantly predicted 55% of the new coronavirus ANXIETY. It seems that the high ANXIETY level of COVID-19 in students, can enhance their ANXIETY and SENSITIVITY about health state and they would exaggerate physical and emotional symptoms. Thus, the University's psychological and Counseling Services must take steps to reduce the ANXIETY of COVID-19 and increase students' awareness.

Background and purpose: New theories about social ANXIETY focus on the cognitive processes such as metacognition and ANXIETY SENSITIVITY. The purpose of this study was to determine the effect of metacognitive beliefs and ANXIETY SENSITIVITY in social ANXIETY disorder. Materials and methods: In a correlational study, 261 university students (118 males and 143 females) were selected using convenience sampling in 2013-2014. Participants completed the ANXIETY SENSITIVITY Index (ASI; Reiss et al., 1986), Metacognition questionnaire (Wells, 2004) and Social Phobia Inventory (Canoor, 2000).Results: The mean ages of male and female subjects were 23±2.74 and 20±2.60, respectively. The results indicated significant relationship between some components of metacognitive beliefs and social ANXIETY (t=6.28, P<0.001). Also, social ANXIETY was predicted by the components of ANXIETY SENSITIVITY.Conclusion: This study showed the effects of ANXIETY SENSITIVITY and metacognitive beliefs on social ANXIETY.

The purpose of this study was to investigate the relationship between ANXIETY SENSITIVITY and metacognitive beliefs with test ANXIETY in students. The population of the study consisted of all high school students in Naghadeh city in the academic year of 2016-2017. 290 students were selected through multi-stage random cluster sampling. To collect data, the test ANXIETY scale, meta-cognition questionnaire and ANXIETY SENSITIVITY questionnaire were used. Pearson correlation coefficient and regression analysis were used to analyze the data by SPSS ver. 21. The findings showed that there is a significant relationship between metacognitive beliefs, ANXIETY SENSITIVITY, and test ANXIETY (0. 01). Also, the result of regression analysis revealed that approximately 21% of the test ANXIETY variance was predicted based on the metacognitive beliefs and ANXIETY SENSITIVITY variables. Therefore, it can be concluded that with increasing metacognitive beliefs and ANXIETY SENSITIVITY, the amount of test ANXIETY is increased. In other words, metacognitive beliefs and ANXIETY SENSITIVITY are important variables in students' test ANXIETY.
