Objectives The current study aimed at validating the Integrated Motivational-Volitional Model of suicidal behavior in Iranian students. Methods The population of the current descriptive correlational and structural equation model included all students of Ardabil city among which 520 people of Mohaghegh Ardabili University students were selected as the sample.

A comprehensive understanding of how suicidal risk factors interact with one another to increase the frequency of suicide ideation and attempted suicide is critical for improving theoretical models of suicide and prevention efforts. The aim of the present study was to explore the prediction of suicide ideation formation and its transition to suicide attempt through the interactions of the constructs suggested by the IPTS, IMV and 3ST theories, as well as other clinical factors. The core constructs of several theoretical models were assessed using a battery of scales administered to 909 Iranian college students. The results supported Klonsky's 3ST and O’Connor's IMV models and, in addition, the relevance of non-suicidal self-injury, the acquired capacity for self-harm, sexual abuse, and exposure to family self-harm for the transition from suicide ideation to a suicide attempt. Depression and PTSD were background factors rather than risk factors for suicide ideation or suicide attempt. Limitations were that the information provided by students may have been biased due to the stigma surrounding suicide in Iranian culture, and the proportion of female students was high.

Background: Impulsivity is an important factor associated with high risk behaviors. The new findings reveal the neuropsychological bases for this personality trait. Objectives: The current study aimed to investigate the relationship between quantitative electroencephalography (QEEG) connectivity indices in FP1 / Fp2 brain areas and multiple facets of impulsivity among college students. Patients and Methods: The current correlational study was conducted on all students of the University of Mohaghegh Ardabili in 2015-2016 the academic year as the statistical population. Eighty-eight students were randomly selected and asked to respond to the questionnaire of demographic information and impulsive behavior scale, then they were brought into the laboratory of psychology, located in the Faculty of Educational Sciences and Psychology of the University of Mohaghegh Ardabili and their EEG activities were recorded for six minutes both under opened eye and closed eye conditions. The data were analyzed with NeuroGuide and SPSS version 23. Results: The current study results showed a positive relationship between negative urgency and delta activity in closed eye condition in FP1 / Fp2 areas. Also, beta activity in opened eye condition in FP1 / Fp2 areas was negatively correlated both to lack of premeditation and positive urgency. Moreover, there was a significant relationship between high beta activities in closed eye condition and the lack of perseverance. Conclusions: The obtained results were consistent with prior findings highlighting the importance of the high beta and low delta activity in prefrontal lobe in impulsive behaviors.
