 One of the phenomena of adolescence is risky behaviors. Many biological, cognitive, social and family factors are the cause of high-risk behaviors. The aim of this research was to predict the tendency to risky behaviors based on the behavioral brain system with the mediating role of parenting styles.

 This descriptive study of the correlation and path analysis type was conducted with the participation of 360 students less than 18 years of secondary school in the 4th region of Qom province in the academic year of 2001-2012 with available sampling. Data were collected using high-risk behaviors and behavioral brain system questionnaires and were analyzed using Pearson's correlation coefficient tests and path analysis and SPSS- Statistics for Windows, version 22.0 (SPSS Inc., Chicago, Ill., USA).

 Our study showed a correlation between all predictive variables and high-risk behaviors. The path analysis test showed that, from the direct path, the relationship between behavioral inhibition system (β=0.19) and permissive style (β=0.26) was positive and significant with high-risk behaviors. However, the relationship between the activator inhibition system (β=0.16) and authoritarian style (β=0.21) with high-risk behaviors was negative and significant. From the indirect path, the relationship of behavioral inhibition system with the mediation of permissive style (β=0.083) and authoritative style (β=0.053) with risky behaviors was positive and significant. Whereas, the relationship of behavioral activation system with the mediation of permissive style (β=-0.138) and authoritarian style (β=-0.088) with high-risk behaviors was negative and significant.

The study showed that both inhibition and activation systems were directly related to high-risk behaviors and through two permissive and authoritative styles. The evaluated model has a good fit.

This study aims to assess the mediating role of Cognitive Emotion Regulation (CER) strategies in the relationship between brain-behavioral system activity and marital satisfaction.

This is a descriptive correlational study. The statistical population consists of all married men and women referred to two clinics of petrochemical industries in Mahshahr, of whom: 200 (106 female and 94 male) were selected using a convenience sampling method. Data collection tools were the Gray-Wilson Personality Questionnaire, ENRICH Marital Satisfaction Scale, and the Cognitive Emotion Regulation Questionnaire (CERQ). Pearson correlation test, multiple regression analysis and path analysis were carried out in SPSS v.17 and LISREL v.8.8. 

All dimensions of CER (negative and positive strategies) and the activity of brain-behavioral system were significantly associated with marital satisfaction. Both negative and positive CER strategies and two Behavioral Activating System and Fight/Flight System as components of the brain-behavioral system had direct association and the Behavioral Inhibition System component had indirect association with marital satisfaction. They had good predictive power to predict marital satisfaction in families. 

 The brain-behavioral system activity, as a biological model of personality, and the use of CER strategies have can predict marital satisfaction.

One of the debates in psychology is the relationship between physical illnesses and the resulting psychological and psychological phenomena that can cause extensive harm to the individual. The purpose of this study was to model the causal relationships of behavioral brain system on psychosocial vulnerability by mediating the role of anxiety Distress tolerance with asthma.

The method of this research was descriptive-correlation based on structural equation modeling. The statistical population of the present study consisted of all 500 patients with asthmatic disease in District 2 of Tehran (Vanak region) in the specialized clinic of respiratory asthmatic patients in 1398. In this study, to determine the sample size according to the number of observed variables and assign a coefficient of 10 for each observed variable (24 variables observed in the model), and taking into account the possibility of incomplete questionnaires of 250 people as a sample size by purposeful selection Were. Carver and White Behavioral Brain Systems Questionnaire, Carpenters and Davoodi Psychiatric Injury, Simmons and Gaher Distress Tolerance Questionnaire were used to collect data. Regression equation tests were used to analyze the data.

The results showed that the behavioral brain system through Distress tolerance has an impact on the psychiatric vulnerability of asthmatic patients and the effects of direct and indirect pathways 63% of the variable of psychological vulnerability can be explained by the brain behavioral system Distress tolerance. In general, the research model was approved.

Considering the presence of psychological factors in asthma and identifying the role of emotional and anxiety factors in the extent of mental injury in patients, it is recommended that therapists consider protocols based on cognitive behavioral patterns in this group of patients.

Internet addiction means excessive and unnecessary use of the Internet. The aim of this study was to investigate the role of brain-behavioral systems in Internet addiction among university students.

This was a descriptive and correlational research. The statistical population was all the students of Islamic Azad University, Karaj Branch in the academic year 1397-98. A sample of 162 students were selected, based on the Tabachnick & Fidell formula, using the multi-phase cluster sampling technic. The tools used to collect data were the harmful Internet use and the brain and behavioral system questionnaires.

Based on the multivariate regression analysis, 66.7% of Internet addiction among the students could be explained by brain-behavioral systems.  Active avoidance and approach, as components of the behavioral activation system, could predict Internet addiction negatively, while passive avoidance and extinction, as components of the behavioral inhibition system, and fight and flight from the components of the fight/flight system, could predict Internet addiction positively.

Purposeful communication and information search (pleasant unconditional stimuli), tedium and constant logic dominating the internet environment (unpleasant unconditional stimuli) have their own conditional cues on the Internet that indicate the degree of susceptibility of brain-behavioral systems to internet addiction.

Considering the importance of brain structures and functional systems in psychopathology and considering the research gap in comparing brain / behavioral systems, this study aimed to compare brain / behavioral systems in cardiovascular patients, individual’s Compulsive obsessions and ordinary people were performed.

The research method was applied in terms of purpose and 2-comparative in terms of implementation method. Data from 150 people including 50 healthy people, 50 cardiovascular patients referring to Tehran medical sciences hospitals for medical examinations in Tehran and 50 obsessive-compulsive patients referring to psychology and psychiatric clinics in Tehran in 1397 Was collected. Research samples using the method in Doss were reduced. The Gary-Wilson personality questionnaire was used as a research tool. Data were analyzed using analysis of variance and Scheffe post hoc test.

Analysis of variance showed that there was a difference between the dimensions of brain / behavioral systems in cardiovascular patients, obsessive-compulsive disorder and normal people (p≥0.01). Post hoc test showed that in the components of passive avoidance, the group of heart patients was more than obsessive and in the components of active avoidance, extinction, war, escape, escape / avoidance system, the group of obsessive was more than the other group Was (p≥0.05). In the component of behavioral activation system, heart patients were more than normal people, but this difference was not significant with the group of obsessive-compulsive patients.

Cardiovascular disease and obsessive-compulsive disorder have a significant relationship and can be appropriate components in psychological analysis of the occurrence of these disorders.

The association between depression and brain systems has received both theoretical and empirical support. However, less is known about the behavioral brain systems and postpartum blues in this relationship. This research investigates the role of neuropsychological structures in postpartum blue: According revised reinforcement sensitivity theory.

The present study was a descriptive correlational research. Study population included all referred females who diagnosed as mothers with postpartum blues in health centers of Mashahd city during 2018. A total sample of172mothers with postpartum blues selected with Multi-stage cluster sampling method. The participants completed brain behavioral systems Scale and Edinburgh Postpartum Depression Scale. Collecteddata were analyzed by a stepwiseregression model.

The results showed that the behavioral inhibition system has a positive and significant relationship And behavioral activation system had a negative and significant relationship with postpartum blues in alpha level (0.01).The results also indicate that 15% of the variance of postpartum blues is explained by behavioral activation system and 10% of its variance can be explained by behavioral inhibition system. These two variables are the strongest predictors of postpartum blues.

In order to conceptualization postpartum blues disorder, we need to consider the role of behavioral inhibition system.
