Aim and Background: The behavioral inhibition system (BIS) and the behavioral activation system (BAS) are considered as factors to verify the effects of personality significance on cortical activity. The present study explored the effects of the BIS and BAS on frontal asymmetry in response to affect stimuli. Methods and Materials: This study included 36 individuals (18 with high BAS sensitivity and 18 with high BIS sensitivity, 17 women). All subjects were introduced to neutral, happy, and sad conditions by the International Affective Pictures System (IAPS) and brain waves were recorded simultaneously. Finally, absolute power of alpha band (8-12 Hz) of the right and left frontal areas were calculated for each participant. Findings: A mixed repeated measurements analysis of variance (ANOVA) was used to analyze the absolute alpha power. Results revealed an increased response to neutral stimuli in BAS group within the left frontal area. However, no significant effects were found in the BIS group in this condition. In addition, an increased left frontal activity (alpha decreasing) in response to happy pictures was seen in the BAS group. On the other hand, an increased right frontal activity (alpha decreasing) in response to sad pictures was found in the BIS group. Conclusions: The results were consistent with the approach/withdrawal model and cerebral asymmetry. The role of the frontal region in positive and negative moods was also approved.

Abstract Aim and Background: The aims of this study were to investigate risk factors for suicide attempte and compered it’s with non attempters. Methods and Materials: In a case-control study, 120 individuals suiside attempeter who had presented to Shahid Madani in the city of Azarshahr were compered with 140 control who were selected using conveniennce sampling, and were matched by a number of demographic factors with each other. Data were gathered using Family Assessment Device (FAD) , Coping Style Questionnaire and researcher-made stressor life events checklist, and were analyzed via Logistic Regression and T-test. Findings: Suicide attempeter had a poor performance in family features such as relation (p=0.02), problme solving (p=0.001), roles (p=0.001), sentiment sensitivity (p=0.01), sentiment involvement (p=0.001) and family general function (p=0.001) ,use emotion oriented coping style in general (p=0.001) and experinced stressor life events more than non attempters (p=0.001). 66 percent of the variance related to the suicide attempt is due to problme solving, family general function, problem oriented coping style and stressor life events, among which stressor life events (58 precent) and family general function had the lowest (1 percent) share. Conclusions: Unfavorablefamily features , ineffective coping style and stressor life events can lead to increased psychological issues such as suicide attempt.

Aim and Background: In terms of the inherent characteristics of the military career, law enforcement personnel as human resources of NAJA (Law Enforcement Force of the Islamic Republic of Iran) organization face multiple occupational issues; and as a result, they are more exposed to psychological vulnerability than other employees. The purpose of this study was to determine the effect of promoting individual and social mental health on psychological well-being of law enforcement personnel in Tabriz, Iran. Methods and Materials: This study was a semi-experimental research with pre- and post-test design and control group. The statistical population consisted of the law enforcement personnel of Tabriz in 2017. Of them, 30 people were selected by purposeful sampling method and divided into experimental and control groups. The experimental group participated in mental health promotion program for 10 sessions of 45 minutes. Then, they were tested. Ryff’s Scale of Psychological Well-being (SPWB) was used to collect data. Data were analyzed using descriptive methods including mean, standard deviation (SD), and multivariate analysis of covariance (MANCOVA) through SPSS software. Findings: The mean of psychological well-being in NAJA staff after intervention in post-test was increased in the experimental group (11.87 ± 1.18) compared to the control group (6.33 ± 1.04), (P < 0.01). Conclusions: The study showed that individual-social mental health promotion program can be used as an appropriate intervention for increasing the psychological well-being of law enforcement personnel.

Aim and Background: Adolescence is considered as a critical period for early diagnosis and intervention to prevent suicidal behavior, so the etiology of effective factors for suicide is essential. Therefore, the present study was conducted with the aim of investigating the role of impulsivity, dark personality traits, perceived social support and anxiety sensitivity in predicting students' suicidal thoughts.
Methods and Materials: The type of study was descriptive-correlation. The statistical population of the study was all the male students of the second secondary level in the first district of Ardabil city in 2022-2023 (350 people), who were selected as a sample through the Karjesi and Morgan table and by multi-stage cluster random sampling. The research tools included the Impulsivity Scale by Barratt & et al (1995), Johnson and Webster's Dark Personality Traits Scale (2010), Zimet & et al's Perceived Social Support Scale (1988), Reiss and Peterson's Anxiety Sensitivity Questionnaire (1986), and Beck's Suicidal Ideation Scale (1991). Collected data were analyzed using Pearson's correlation coefficient and multiple regression analysis simultaneously in SPSS version 18 software.
Findings: According to the results, there is a relationship between impulsivity 0.69, dark personality traits (Machiavellianism 0.55, narcissism 0.57 and psychopathy 0.50), perceived social support -0.36 and anxiety sensitivity 0.69 with suicidal thoughts in male students. Statistical significance was observed. Also, using 0.64 multiple regression, suicidal thoughts of male students were explained by variables of impulsivity, dark personality traits, perceived social support and anxiety sensitivity.
Conclusions: Considering the impact of impulsivity, dark personality traits, perceived social support, and anxiety sensitivity in students' suicidal thoughts, it is suggested that psychologists and specialists pay more attention to the role of these variables to reduce students' suicidal thoughts
