Research methodology: A Sample of 411 people using cluster sampling from real clients of Razi insurance of west of Mazandaran province was selected by questionnaire that was adopted of two surveys Skarmeas and Leonidou (2013) and Iran et al (2011) and hypotheses were tested by means of structural equation model. Research results: Skepticism to social responsibility would effect on the level of price sensitivity while the hygiene factors are not observed in the organization but as long as the organization is in compliance will have little effect. While resilience to negative information, as well as fairness and word of mouth advertising has a positive impact on price sensitivity. Research limitations: Limitations exist since very little research has been done in the field of skepticism and its effects on the price sensitivity in the field of marketing. Such a plan is suggested to conduct to generalize more in the other insurance firms. Managerial usages of the research: According to the findings, branches should find staffs that have acceptable expertise. It means that they have features include: Sufficient awareness of the relevant insurance services, the speed of doing things, provide better services, identify customer needs, performance, etc. Research innovation: Skepticism in the area of marketing services has not been evaluated in Iran.

Price mavenism, which is associated with price- information searching and price- sharing behavior, is often considered a negative dimension of price. The purpose of this paper, however, is to propose price mavenism as an outcome variable arising from both positive perceptions of price (prestige sensitivity) and negative perceptions (price and value consciousness) and examine that the price mavenism will positively impact on the shopping hedonism among the Iranians. Data were collected through a questionnaire of Islamic Azad university students of Arak. The conceptual model was tested using structural equation modeling. This study found that prestige sensitivity, Price consciousness and value consciousness shaped price mavenism among the Iranians, supporting the idea that price mavenism arises from both positive and negative perceptions of price. While value consciousness was positively associated with shopping hedonism, price consciousness per se was not. Manuscript profile -

The aim of this study was to evaluate the field prevalence and typing of Listeria monocytogenes in the local fish market of Shahr-e Kord, Iran. Antibiotic susceptibility of the isolated Listeria was also carried out by the antibiotic disc diffusion method using 13 different antibiotics. A total of 100 rainbow trout were randomly collected from retail market in Shahr-e Kord for examination of the prevalence and typing of Listeria species using biochemical methods. Four isolates of Listeria were identified; One isolate of L. inovaii and 3 islolates of L. monocytogenes. All four isolates showed the highest antibiotic sensitivity (100 % susceptibility) to five antibiotics including cotrimoxazole, tetracycline, gentamicin, erythromosine, and vancomycin. However, all strains showed resistance to oxacillin. As L. monocytogenesis is of the most important pathogens in humans, fish contamination to different species of Listeria could be a potential risk and requires more attention. Manuscript profile -

The complexity of the scouring mechanism has made this one of the most important fields of civil engineering studies. In recent years, many studies have been performed on local scouring around bridge piers. Due to the great importance of predicting and estimating the scour pattern in the vicinity of bridge piers, many studies have been done on this type of structure.Method: In this study, for the first time, using a new extreme learning machine (ELM) method, the scour depth near the foundations of the twin bridges was simulated. First, effective parameters were identified and four ELM models were developed. Then, numerical results were validated using Monte Carlo simulation and the cross-validation method. Then the sin activation function was determined as the best activation function. In addition, ELM results were compared with artificial neural network (ANN) models that ELM models estimated scour values more accurately. Uncertainty analysis was performed for the superior ELM and ANN models and a relationship was proposed for the superior model. Partial derivative sensitivity analysis (PDSA) was also performed for all input parameters.Results: Among the existing activation functions, the sin function had the optimal performance compared to other activation functions. According to the analysis of modeling results, ELM 1 model was introduced as the superior model. This model was a function of all input parameters. Also, by removing the landing number, the accuracy of the numerical model was significantly reduced, so the mentioned parameter was identified as the most effective parameter in scouring modeling around the bases of the twin bridges by the model of Strength training machine.Conclusion: By analyzing the modeling results the superior ELM model was introduced. The results of ELM models were also compared with ANN models, which showed that ELM models simulate scour values more accurately. For the superior ELM model, a relation was proposed to calculate the scour hole depth, and further uncertainty analysis showed that this model had a higher performance than the actual value. In addition, the relative derivative sensitivity analysis for the input parameters showed that with increasing the landing number, the value of the objective function (scour depth) increases.

Initially, all the parameters affecting the scour depth in the vicinity of cross-vane structures are identified and then using these parameters, six different models are defined for each of the GMDH and GSGMDH methods. By analyzing the results yielded by the artificial intelligence models, the superior models are introduced. The GMDH and GSGMDH superior models estimate the scour values in terms of all input parameters. In addition, the accuracy of the GSGMDH models is higher than that the GMDH ones. For example, for the GMDH and GSGMDH superior models, the values of "variance accounted for" in the test mode are calculated 73.075 and 86.408, respectively. Also, the superior model forecasts the objective function values with acceptable accuracy. For example, the correlation coefficient (R), the scatter index (SI), and the Nash-Sutcliffe model efficiency coefficient (NSC) for the GSGMDH superior model in the training mode are approximated 0.913, 0.214 and 0.800, respectively. Based to the results of the sensitivity analysis, the shape factor of cross-vane structures, the ratio of the difference between the upstream and downstream flow depths to the height of the structure and the densimetric Froude number (Fd) are introduced as the most effective input parameters. An uncertainty analysis exhibits that the GSGMDH superior model has an underestimated performance. Manuscript profile -

It is constantly affected by natural motion and human interference in the balance of nature. Generally speaking, everywhere in the world coastal areas are very resourceful and provide better condition for human habitat, and therefore, attract human populations and become centers for civic developments. As a result of excessive use, and in some cases abuse of the resources by human beings, adverse conditions develop and cause a decline in coastal areas ecosystem such as; mangroves, coral reefs, cliffs, beaches, tidal flats and estuaries. Such condition makes it imperative to draw urgent attention for protection and rehabilitation of coastal areas. In current research the Environmental Sensitivity Index (ESI) of NOAA and the Particularly Sensitive Sea Area (PSSA) method of IMO were applied to the region under consideration. These methods are credible and worldly accepted for such investigations, in particular where pollutant source include petrochemical materials. The result of study utilizing Internal Factor Evaluation (IFE) and External Factor Evaluation (EFE) matrices of the Strengths-Weaknesses-Opportunities-Threats (SWOT) way of analysis indicated that both methods produce acceptable results with scores above 3.0. However, weighted scores of NOAA method, using both IFE and EFE matrices, came out somewhat higher than those for IMO method, and considered better choice for application in the coastal areas of Siatan and Baluchestan province.

Despite the fact that such areas are benefiting from verity of biological resources of marine and inland systems, they are exposed to destructive threats from both systems. Nowadays, one of the main sources of threat is the large probability of occurrence maritime accidents that caused oil spill. Therefore, identification of sensitive coastal areas and its protection against pollutants such as petroleum products has become a priority for coastal countries. The purpose of this research is to introduce a guideline for mapping of Environmental Sensitivity Index (ESI), as a tool for identification of coastal areas, sensitive to oil spill, developed by National Oceanic and Atmospheric Administration (NOAA) of United States of America. The goal of such identification is timely response to oil spill and cleanup process for protection of the various coastal ecosystems. In past few decades, Environmental sensitivity analysis and mapping projects have been carried out in many Countries, along thousands of kilometers of shoreline around the world, primarily as a part of national efforts to establish a knowledge-based response system to spilled oil that may affect the coastline.

An ex-post- facto design was used as the research design. The population included all patients with non-cardiac and cardiac chest pain who referred to Shiraz health centers in 2013. Subjects were 50 cardiac patients (28 females and 22 males), 50 patients with non-cardiac chest Pain (29 females and 21 males) and 50 people as normal matched group (27 female and 23 male) within 22 to 81 years old age range who were selected through purposive sampling method. The instruments for data collection consisted of Anxiety Sensitivity Index (Taylor & Cox, 1998), Coping Inventory for Stressful Situations (Parker & Endler, 1990), and a researcher-made demographic information checklist. Then the data was analyzed with one way analysis of variance and chi square. Results indicated that both cardiac and non- cardiac chest pain patients significantly are lower than normal matched group in using problem solving coping strategies (P<0.01) and higher in using emotional (P<0.01) and avoidance coping strategies (P<0.05). Results also indicated that non-cardiac chest pain patients showed highest sensitivity to all 6 subscales and normal group showed lowest sensitivity. In this regard, patients with cardiac disease could stand between the two groups and both groups of patients were significantly different from the normal healthy group (P<0.05). As a conclusion, psychological variables such as anxiety sensitivity and coping stress strategies can predict pain frequency, severity and treatment seeking especially for patients with Non –cardiac chest pain.

This study was a quasi-experimental design as pretest-posttest with the control group. The statistical population consisted of all 11th grade students of Karaj Secondary School in the academic year of 2018-2019 which were determined based on the screening score in the pre-tests. 30 students were randomly selected to answer two research questionnaires, including the Puklek Adolescent Social Anxiety Scale (Puklek, 1997) and the Boyce & Parker International Personal Sensitivity Questionnaire (Boyce & Parker, 1989). The experimental group received the psychodrama treatment during 8 sessions 90min. After the end of training, the students of both groups were reassessed by the mentioned tests. Result of multivariate analysis of covariance showed that, the test group in comparison with the control group had a significant reduction in social anxiety disorder and interpersonal sensitivity scores (P≤0/01). Therefore, psychotherapy by using the art of drama in treatment and applying and making changes, both externally and objectifying internal imaginations and tendencies, creating new realities, causes an outpouring and psychological refinement of the individual and increases mental health and also decrease the symptoms of anxiety and sensitivity in a person's relationship.

The creation of very small grooves with sub-wavelength sizes (nanometers) on a thin metal film leads to a significant increase in the sensitivity associated with molecular absorption. By concentrating light within the grooves, the peak wavelength shift is improved. When the groove is engraved inside the structure, the sensitivity improves to 8.4 times more than the grooveless structure. The sensor functions for plasmonic structures with symmetric and asymmetric grooves have been investigated and it is shown that the proposed sensor is capable of performing biomolecular detection in multiplex form.

Method: The current study employed a quasi-experimental design with pre-test, post-test, and follow-up assessments, using a control group. Among all 470 individuals seeking treatment for opioid use disorder at Nasim Rahaii Treatment Center in 2022, 60 participants were conveniently selected and randomly assigned to three groups of 20 individuals. The research instruments included the standard Mental Health Questionnaire (Keyes, 2002) and the Rejection Sensitivity Questionnaire (Feldman, 1996). The first experimental group received 8 sessions of problem-solving skills training, the second experimental group received 10 sessions of self-talk training, and the control group did not receive any intervention. Data were analyzed using repeated measures analysis of variance. Results: The findings indicated that both training methods had a significant effect on reducing rejection sensitivity and improving mental health in individuals with opioid use disorder. Additionally, the follow-up analysis using Bonferroni test showed that problem-solving skills training was more effective than self-talk training in reducing rejection sensitivity. However, no significant difference was observed between the two methods in terms of their impact on mental health. Conclusion: Consequently, addiction specialists and therapists can incorporate these training approaches alongside pharmacotherapy and other conventional methods to enhance psychological functioning and prevent relapse in individuals with substance dependence.

The research method was correlational, structural equation modeling type and the data was analyzed using SPSS version 26 and AMOS version 24 software.Findings: The findings of Pearson's correlation coefficient showed that there is a positive and significant relationship between Machiavellianism with rejection sensitivity, shame with the dimensions of latent marital aggression including love withdrawal and social sabotage, but there is no significant relationship between narcissistic personality and rejection sensitivity, shame, love withdrawal and social sabotage. Anti-socialism had a positive and significant relationship with rejection sensitivity, shame and social sabotage; but it was not related to love withdrawal. Also, there is a positive and significant relationship between rejection sensitivity and shame with love withdrawal and social sabotage. The findings of structural equation modeling showed that Machiavellianism, anti-socialism, rejection sensitivity and shame positively predict love withdrawal and social sabotage. Narcissism has no direct or indirect effect on love withdrawal and social sabotage. The findings provide a deeper understanding of the mediating role of rejection sensitivity and shame in the relationship between Machiavellianism and anti-socialism with love withdrawal and social sabotage among women. From the results of this study, it can be concluded that women's rejection sensitivity and shame in relation to dark triad personality traits of Machiavellian and antisocial personality are related to latent marital aggression.

The aim of this study was to investigate the occurrence and diversity of Listeia spp. in traditional cheeses of Tabriz area and to assess antibiotic resistance, biofilm formation and thermal-resistance of the isolates. A total number of 100 traditional cheese was collected randomly. Listeria spp. were isolated and identified using conventional culture methods. According to the results, 12 out of 100 cheese samples were found positive for Listeria spp. Amongst, 5 and 7 isolates were identified as monocytogens and ivanovii, respectively. The highest rate of resistance was observed for oxacillin (100%) and nalidixic acid (75%), and the highest rate (100%) of sensitivity was related to cotrimoxazole, tetracycline, gentamicin, erythromycin and vancomycin. Results of biofilm assay reveled that all 5 strains of L. monocytogens produced low amount of biofilm, meanwhile strains of L. ivanovii produced a range (weak, moderate and high) of biofilm level. Based on thermal-resistance outcomes, thermalisation process had insignificant impact on Listeria strains; whereas application of “rapid pasteurization” process for 5 sec, reduced the populations of both Listeia specis to below the detectable limit (P <0.01). In the case of batch pasteurization, two Listeria species demonstrated significant (P <0.01) degree of resitsnce. Since L. monocytogenes, and in a lesser extent L. ivanivi are human pathogens of concern, it was concluded that traditional cheeses of Tabriz area could pose a health hazard dealing with Listeria.

The main treatments were included the rainfed and irrigated cultivation, and the sub-treatments were included the cultivars of Sorkh tokhm (E1), Backcross Roshan (E2), Bam (E3), Azar2 (E4) and Kavir (E5). The experiment was performed in a randomized complete block design with three replications. The yield components (average in the rainfed and irrigated cultivations) were measured for Sorkh tokhm, Backcross Roshan, Bam, Azar2 and Kavir cultivars by 5322, 6702, 6122, 4621 and 4259 kg. ha-1 (grain yield) and 4790, 6402, 5411, 4299 and 4013 kg. ha-1 (straw yield) respectively. From the rainfed to irrigated cultivation, the yield was increased by 57%, 100%, 82%, 41% and 36% (in total yield), 40%, 93%, 60%, 30% and 29%, (in straw yield) and 75%, 106%, 105%, 53% and 43% (in grain yield), respectively. The relationship between grain yield (X) and straw yield (Y) was fitted as Y=0.867X in the irrigated cultivation and Y=1.017X in the rainfed cultivation. For evaluation the cultivars susceptibility to drought stress, were used the indices of MP, GMP, TOL, SSI and STI for grain and straw yields components. As a result, for selecting the optimal cultivar (in Qazvin region), the priority was given to cultivars of Backcross Roshan, Bam, Sorkh tokhm, Azar2 and Kavir, respectively. If water is supplied for irrigation, the yields of grain and straw will increase to double in the cultivation of Backcross Roshan cultivar. Manuscript profile -

The seasonal moving average of IR Rial to US Dollar rate from spring 1392 to spring 1401 is the proxy of exchange rate as the dependent variable and balance of trade, debt to GDP, GDP, inflation rate, liquidity volume, OPEC oil price and unemployment rate are considered as the independent variables. For determining the factors influencing the exchange rate, Sobol' Sensitivity Analysis, a machine learning method, is used and VECM is harnessed for regressing and forecasting. Variance decomposition and impulse response function are also utilized as instruments of VAR for measuring the future shocks effects of independent variables on exchange rate and the periods in which these shocks will be neutralized. The results show that liquidity volume, oil price, unemployment rate and inflation rate are the most significant determinants, respectively and the future shocks of liquidity volume, inflation rate, oil price and unemployment rate have the longest period of impacts on the exchange rates, respectively. The study outcomes also show an affinity between econometric and machine learning results in this case. The predicted amounts of exchange rate until winter 1402 are also included in the results.

The results of Chi-Square test indicated significant differences between observed and expected values among the variables in different ages. Mothers of 36-40 month children, in comparison with younger and older children’s mothers, were more likely to show "non-balanced" representation and low sensitivity. This result may be due to emerging negativity and independency during this age period and the mother's difficulty to adjust herself with these behavioral alterations. So caregiver may not be able to maintain her role as a sensitive and secure base as before. These findings suggested the impact of mother-child communication on child attachment security during development and the need to provide mothers with age-appropriate educational interventions.

The area, which contains GorganGulf and Miankale Wetland, is recorded as an international wetland in Ramsar Convention. It has high potential for tourism activities. Moreover, the increasing trend of economic development, especially oil activities in adjacent countries reveals the necessity of management and conservation of these coasts. The aim of this study is management of the coastal area by applying NOAA models and Environmental Sensitivity Index (ESI). Physical sensitivity division of coasts has been done based on field surveys and using satellite images and Geographical Information System (GIS). The assessment of physical factors including wave energy, slope and bed substance in the region under study showed that the western parts of Miankale coasts are categorized in the forth class of NOAA classification and the central part of these coasts is regarded in 9B class. Gomishan, Khajeh Nafas, Chalasht and Gorgan Gulf2 are classified as 10D according to NOAA classification. The results of this study indicated that not only physical diversity, including geomorphologic characteristics and the bed substrate of these coasts, is low but also there are sensitive biological resources in the region. For these reasons, if oil pollution occurs, pollutants may remain in coastal areas for a long time. Therefore, more attention should be paid to manage the coastal areas in this region.

An important parameters on phenology can be suggest temperature and photoperiod. This study was conducted with 12 sowing dates to quantify response of jointing rate (JOR) to temperature and photoperiod in wheat cultivars. The regression models fitted to JOR against temperature were beta, dent-like and segmented function. Meanwhile, quadratic, negative exponential and segmented models fitted to JOR against photoperiod (these models were used as 9 combined models to describe JOR as a function of photothermal day). The results showed that beta- quaradic function was the best model to describe JOR as a function of both temperature and photoperiod. Using this function, the base, optimum and ceiling temperatures were estimated 4.5, 27.3 and 40 ₒC respectively. Critical photoperiod and photoperiod sensitivity coefficient were estimated 20.02 to 22.69 hour and 0.0109 to 0.0475 respectively. Also biological day for cultivars between emergence to jointing with the beta- quaratic function examin between 25.2 to 31.9 days.The results of this study can be used in crop simulation models.

To examine the effect of cold stress effects on rice seedling growth was carried out a greenhouse experiments in Deputy of Rice Research Institute in Mazandaran (Amol) since 2010. The basic design was conducted a completely randomized with split plot factorial experiment in 3 replicates with different temperature levels (10, 13, 16, 32 ° C) and its duration (1, 2, 3, 4, 5 days) on five varieties of rice (Dialam, line 843, Tarom, Fajr, Shiroudi). The varieties were designed as main plot and and temperature levels and duration of thermal treatment in sub-plot. The seedlings were placed in normal growth conditions until the 3-2 leaf stage seedlings age (12-8 days) and then transferred to a growth chamber and were treated at 10, 13, 16 ° C for 1, 2, 3, 4 and 5 day. After the treatment, four seedlings from each replicate were selected and growth characters such as height, seedling dry weight (dry weight of shoot + root), sensitivity index, leaf area and color were measured. Results showed that among the varieties, the stress intensity, stress duration and their interaction effects were a significant probability of 1% for all traits in the seedling stage in which reflects the severity and duration of cold stress on the varieties is discussed. Low temperatures were reduced, the growth rate of seedlings up to 10 -50% compared with control treatment. Low temperatures (10 oc) were decreased new roots production and seedling dry weight in which 60% reduction compared to 32oc treatment. Temperature was caused discoloration of lamina and the color of the leaves of rice seedlings after exposure to cold stress conditions could be concluded, each variety is greener leaf color of seedlings with less damage and is more tolerant to cold. Tarom and Shiroudi varieties compared to other varieties more tolerant to cold stress, however, Fajr variety was more sensitive. Manuscript profile -

In this research, for the first time, the fracture toughness, strain rate sensitivity and plasticity of sputter deposited tantalum nitride thin films have been evaluated using nano indentation technique and SEM micrographs. It was shown that the fracture toughness was increases from 0.6 to 7.8 MPa√m with increasing the nitrogen in sputtering chamber. This increase was attributed to the structural evolution from a hexagonal γ-Ta2N phase to the hexagonal ε-TaN and face centered cubic δ-TaN phases, determined by X-Ray Diffraction analysis. The plasticity of the TaN films evaluations indicated that the ratio of plastic work to total work was increased from 50% to 57% and 80%with phase variation from γ-Ta2N to ε-TaN and δ-TaN, respectively.

The statistical population consisted of all male Wistar rats of Baqiyatallah University of Medical Sciences in Iran. To create obesity, a high-fat diet was used for 8 weeks. 16 obese rat having similar condition were selected and randomly divided into 2 obese groups (control and aerobic exercise). To prepare a high-fat diet, 1% cholesterol powder and 1% pure corn oil were added to the standard diet of rats purchased from Parsdam Food Company. Rats in animal laboratory under controlled light conditions (12 hours light and 12 hours dark, start of lighting 6 pm and start of extinction 6 am and temperature 22 ± 3 ° C and humidity about 30 to 60%) were maintained. The use of a high-fat diet continued until the end of the study. The aerobic exercise program was performed for 6 weeks in 5 sessions per week with a gradual increase in speed (18 to 22 meters per minute) and time (10 to 55 minutes in the form of running on a treadmill). All rats 48 hours after the last training session were autopsied. The results showed that 6 weeks of aerobic training led to a significant reduction in fasting glucose in obese Wistar rats. On the other hand, it increased AKT1 / PI3K expression and insulin sensitivity in liver tissue of obese Wistar rats (P≤0.05). Manuscript profile -

Using a multi-stage sampling approach and the Delphi method, 150 respondents were selected from the three Senatorial Zones. Primary data were sourced with the aid of a survey and oral interviews. The collected data were analyzed using the vulnerability index, Ordinal logistic regression, and Heckman probit regression. The findings revealed that the socio-cultural characteristics of respondents contributed to their vulnerability to climate change, as indicated by an average livelihood vulnerability index (LVI) of 0.33. Notably, factors such as water availability and adaptation practices exhibited higher vulnerability indices of 0.49 and 0.42, respectively. The overall LVI and LVI-IPCC averages were 0.35 and 0.02, respectively, highlighting the existence of vulnerability among farming households. The results of ordinal logistic regression revealed that age, marital status, education level, and income from agriculture were statistically significant factors determining the level of vulnerability to climate change in the study area. Consequently, the results of the Heckman two-step regression model revealed that age, marital status, household size, education, religion, belief, family structure, and community teamwork were the significant factors affecting the adaptation and vulnerability to climate change in the area. Policy should be geared towards improving the socio-cultural factors for sustainable livelihoods with an income diversification strategy by the government for crop farmers in order to cushion the effects of low income realized from farming activities in the area.

One of these factors is anxiety sensitivity that refers to the fear of the feelings associated with anxiety arousal due to perceived physical, psychological, or social consequences. There is evidence that anxiety sensitivity plays an important role in the persistence and progression of anxiety symptoms in all anxiety disorders. The aim of this study was to investigate the role of anxiety sensitivity and uncertainty intolerance in predicting the severity of coronavirus disease anxiety. For this purpose, a descriptive correlational study was conducted on 128 volunteers assessed in terms of Covid-19 disease anxiety, anxiety sensitivity, and uncertainty intolerance. The results of multiple regression analysis showed the existence of a significant relationship between disease anxiety, anxiety sensitivity, and uncertainty intolerance (p <.001). The results of stepwise regression analysis showed that 30.1% of the variance of coronavirus disease anxiety was explainable by anxiety sensitivity and uncertainty intolerance. According to the results of this study, anxiety sensitivity and uncertainty intolerance can be considered appropriate predictors of coronavirus disease anxiety. Manuscript profile -

The purpose of this study is to examine the moderating role of experiential avoidance in the relationship between anxiety sensitivity and perceived stress among students. For this purpose, 360 students of Islamic Azad University of Tabriz were selected through multistage cluster random sampling method and evaluated in terms of perceived stress, anxiety sensitivity, and acceptance and practice. Regression analysis revealed a positive correlation between perceived stress with anxiety sensitivity and experiential avoidance. Further, it was indicated that experiential avoidance has a significant positive correlation with anxiety sensitivity. Additionally, hierarchical regression analysis showed that anxiety sensitivity and experiential avoidance, alone and in interaction with each other, have the ability to predict the perceived stress. Furthermore, simple slope analysis presented that experiential avoidance has a moderating role in the relationship between anxiety sensitivity and perceived stress; it has an increasing effect so that in both high and low levels of experiential avoidance there is a significant relationship between perceived stress and anxiety sensitivity; however, when anxiety sensitivity and experiential avoidance are at a high level, the amount of perceived stress at the various levels of experiential avoidance (highest and low) is relatively closer. It seems that experiential avoidance has a moderating role in the relationship between anxiety sensitivity and perceived stress. Manuscript profile -

The aim of this study is to determine the effectiveness of cognitive-behavioral therapy on intolerance of uncertainty and anxiety sensitivity. Therefore, in a quasi-experimental research with pretest, posttest, and control group, 30 students diagnosed with generalized anxiety disorder were selected from Robat Karim city’s high schools and randomly assigned to experimental (n=15) and control (n=15) groups. The experimental group received 9 sessions of group cognitive-behavioral therapy and the control group received no intervention. Subjects in both groups were evaluated for generalized anxiety, anxiety sensitivity and intolerance of uncertainty before and after the intervention. The results of analysis of covariance showed that cognitive-behavioral interventions have significantly reduced the symptoms of generalized anxiety disorder, anxiety sensitivity and intolerance of uncertainty. It seems that cognitive-behavioral therapy, through decreasing the level of intolerance of uncertainty and anxiety sensitivity, is an appropriate method in treatment of generalized anxiety.

Method: 307 married women of Tehran city were selected by voluntary sampling method and were answered to the Couples Relational Aggression and Victimization Scale (Nelson & Carroll, 2006), the Short Version of Dark Triad Personality Traits (Paulhus & Jones, 2014), The Test of Self-Conscious Affect (Tangney, 1996) and Rejection Sensitivity Questionnaire (Downey & Feldman, 1996) through an online survey. The research method was correlational, structural equation modeling type and the data was analyzed using SPSS version 26 and AMOS version 24 software. Findings: The findings of Pearson's correlation coefficient showed that there is a positive and significant relationship between Machiavellianism with rejection sensitivity, shame with the dimensions of latent marital aggression including love withdrawal and social sabotage, but there is no significant relationship between narcissistic personality and rejection sensitivity, shame, love withdrawal and social sabotage. Anti-socialism had a positive and significant relationship with rejection sensitivity, shame and social sabotage; but it was not related to love withdrawal. Also, there is a positive and significant relationship between rejection sensitivity and shame with love withdrawal and social sabotage. The findings of structural equation modeling showed that Machiavellianism, anti-socialism, rejection sensitivity and shame positively predict love withdrawal and social sabotage. Narcissism has no direct or indirect effect on love withdrawal and social sabotage. The findings provide a deeper understanding of the mediating role of rejection sensitivity and shame in the relationship between Machiavellianism and anti-socialism with love withdrawal and social sabotage among women Based on the results of this study, it can be concluded that women's rejection sensitivity and shame in relation to dark triad personality traits of Machiavellian and antisocial personality are related to latent marital aggression.
