the temperamental traits are considered as an important risk factor for conduct disorder and the mechanisms of this relations is not clear. The aim of this study was investigating the mediating role of anger rumination in relations of affective temperaments with symptoms of conduct disorder in adolescents

The method of this study was descriptive- correlational. The statistical population included all first and second periods of high school students in Urmia city in the 2020-2021 academic years. Two hundred and twenty people were selected by multistage random sampling method and answered to the strengths and difficulties questionnaire (SDQ), affective and emotional composite temperaments scale (AFECT) and anger rumination scale (ARS). Data were analyzed using structural equation modeling via SmartPLS 3.

The results of structural equation modeling showed that internalized and stalble temperaments has negative direct effect on symptoms of conduct disorder, while the externalised and unstable temperament has positive direct effect on symptoms of conduct disorder. Furthermore, externalized and stable temperaments via negative effect on anger rumination and internalized and unstable temperament via positive effect on rumination have indirect effect on symptoms of conduct disorder (p<0.05).

These results conveals that externalized and unstable temperaments can be act as a risk factor and internalized and stable temperaments can be act as a protective factor for symptoms of concuct disorder. Anger rumination also mediate the relations of affective temperaments with symptoms of conduct disorder.

 Health anxiety is characterized by persistent and severe health concerns and is an important concern for clinical professionals. The purpose of this study was to determine the relationship between the affective and emotional composite temperament model and intolerance of uncertainty with health anxiety symptoms in medical students.

 This study was a correlational- predictive study. The statistical population of this study consisted of students of Kerman university of medical sciences, among whom 211 students were selected by convenience sampling. The research instruments included the health anxiety questionnaire, the affective and emotional composite temperament model scale, and the intolerance of uncertainty scale. The data were analyzed by SPSS software using Pearson correlation coefficient and multiple regression analysis.

 The results of Pearson correlation coefficient showed that among the components of the affective and emotional composite temperament model, depression affective temperament, cyclothymic affective temperament, obsessive affective temperament, and irritability affective temperament and also anger emotional temperament, sensitivity the emotional temperament and the fear emotional temperament with health anxiety had significant positive relationship with health anxiety. However, there was a significant negative relationship between emotional hyperthymic and health anxiety. There was also a significant positive relationship between intolerance of uncertainty and health anxiety. The results of multiple regression analysis showed that the depression affective temperament, obsessive affective temperament, anger emotional temperament, sensitivity emotional temperament and fear emotional temperament and also intolerance of uncertainty can positively and significantly predict health anxiety in medical students. The results also showed that intolerance of uncertainty can positively and significantly predict health anxiety in medical students.

 The affective and emotional composite temperament model and intolerance of uncertainty can explain the symptoms of health anxiety. Therefore, by providing therapeutic interventions based on modulating the emotional composite temperament and reducing intolerance of uncertainty can prevent or control the symptoms of health anxiety.

The aim of this study was to determine the moderating role of affective temperament in the relationship between biomarkers (troponin, white blood cell count, and neutrophil to lymphocyte ratio) and the severity of coronary artery disease.

Coronary artery disease is the leading cause of death among adults worldwide and is considered as an inflammatory disease. Recent studies, in addition to biological factors, have focused on the role of psychological factors in the incidence and severity of this disease.

In this study, 200 patients (145 males, 55 females) with coronary artery disease admitted to Shahid Rajaei Hospital in Tehran in 2018-2019 were selected by continuous sampling. Participants were asked to complete the positive and negative affectivity scale (Besharat, 2014). Also, the number of biomarkers was assessed through blood tests and the number of involved vessels was assessed through angiography and diagnosis by a specialist physician.

The results of hierarchical multiple regression showed that in the first step, 62 percent of the variance of coronary artery disease was predicted by biomarkers, and by entering the interaction between predictor variables (severity of coronary artery disease) and moderating variables (positive affectivity and negative affectivity), explanation of variance of the coronary artery disease increased by 9 percent and reached to 71 percent.

Based on the findings of the study, affective temperament affects the relationship between biomarkers and the severity of coronary artery disease, and therefore, as a psychological factor, could plays an important role in preventing coronary artery disease and decrease the number of deaths and the annual cost of this disease.
