<p class="a"><span lang="EN-US">The Generalized Anxiety Disorder (GAD) is one of the most chronic and detrimental disorders and it is considered a common disorder in childhood and adolescence. Furthermore, this disorder is associated with many problems in the health domain. As such, this study attempted to gauge the impact of mindfulness-based stress reduction on intolerance of uncertainty and anxiety sensitivity among students with generalized anxiety disorder. Therefore, it was attempted to run a quasi-experimental research, including a pre-test, a post-test and a control group, among high schools of Robat Karim in Tehran province. Having used the purposive sampling method, 30 students diagnosed with generalized anxiety disorder, intolerance of uncertainty and high anxiety sensitivity were selected. Then, they were randomly assigned to experimental (15 students) and control groups (15 students). Consequently, the mindfulness program was introduced to the experimental group in 8 sessions and the control group received no treatment. It should be noted that groups were assessed before and after treatment with generalized anxiety scale, anxiety sensitivity and intolerance of uncertainty. The results of analysis of covariance showed that mindfulness-based stress reduction programs significantly reduced the symptoms of generalized anxiety disorder, anxiety sensitivity and intolerance of uncertainty. Since mindfulness reduces the levels of two key components of generalized anxiety disorder, namely intolerance of uncertainty and anxiety sensitivity, it seems appropriate to make use of this program in the treatment of generalized anxiety disorder.</span></p>

The aim of the present study was to compare mindfulness-based cognitive therapy and grammatical mental imagery with cognitive processing on the emotional processing of mothers with children with autism spectrum disorder. Methodology: The research was applied in terms of purpose and in terms of cross-sectional data collection method and quasi-experimental research method was pre-test-post-test with a control group. The statistical population of the present study is all mothers with children with autism spectrum disorder in two schools under education in the city. Ahvaz had 105 students in 2019. A total of 45 mothers with children with autism spectrum disorder were randomly selected and 15 people in the group of cognitive therapy based on mindfulness, 15 people in the group of grammatical mental imagery with cognitive processing and Fifteen people were in the control group. Assessment tools included Baker et al. (2010), mindfulness-based cognitive therapy protocol and grammatically processed grammatical mental imagery protocol. Data analysis using analysis of covariance And was done by SPSS software version 24. Findings: Based on the research findings, the effect of statistical group type (control and experiments) on the recorded scores of emotion processing (p = 0.00, F = 157/407) and the separate effect of the test time variable (p = 0.00, F / 107/15 And the significance of the simultaneous effect of group type and test status (pre-test and post-test) on emotion processing scores (p = 0.00, F = 26.757). Comparing the two methods of cognitive therapy and imaging, a significant level equal to 0.00 and less than the error level of 0.05 has been obtained. Conclusion:Based on the research findings, cognitive therapy based on mindfulness and grammatical mental imagery with cognitive processing is effective on emotional processing of mothers with children with autism spectrum disorder. Also, between the effectiveness of cognitive therapy based on mindfulness and grammatical mental imagery. There is a significant difference with cognitive processing in emotional processing of mothers with children with autism spectrum disorder.

This study is done to determine the effectiveness of Neurofeedback on reducing the symptoms of Hyperactivity and increasing the accuracy and caution in ADHD children. Subjects were 30 ADHD children who were selected by cluster sampling method. Research layout is pre-test, post-test experimental type. Conners parent measure questionnaire and a computer based continuous performance test are the research materials. The results of investigation on post-test average score of Hyperactivity symptoms and accuracy and caution of ADHD children in experimental and witness groups, with controlling of pre-test, has shown a significant difference.
