In this paper, we estimate differences in examination behavior between immigrants and natives, by examining differences in the propensity to forego a passing grade on a final exam in order to retake that final exam. Retaking a final exam involves some level of uncertainty, so differences in examination behavior may be due to differences in motivation, risk-taking, and discipline. We find that immigrants are about 2 percentage points more likely to retake a passed exam than natives. This represents a large difference given a baseline retake rate of about 6.5 percentage points.

Exposure to war can lead to numerous traumatic experiences affecting the daily lives and personal well-being of the civilian population. However, no research to date has examined the associations between postwar well-being and posttraumatic stress disorder (PTSD) symptoms, tendency to forgive, and social support during and following war. Authors examined a sample of 160 Israeli civilians who were exposed to rocket and missile fire during the 2014 Gaza War. Time 1 (Tl) started approximately one week after the beginning of the war and ended four weeks later following the first 72-hour ceasefire declaration by the United Nations. Respondents were re-approached by personal e-mail approximately one month after T1. A structural equation model design showed that higher postwar tendency to forgive, and social support, are associated with higher postwar well-being. It is notable that higher social support during the war had a negative effect on postwar well-being. In addition, higher posttraumatic symptoms and well-being during the war had a positive effect on higher postwar well-being. The study findings reinforce the importance of personal variables in postwar well-being. However, increased awareness of both social support and PTSD symptoms as "double-edged sword" resources is advisable, considering the different effects of social support and PTSD symptoms on well-being both during and after the war., (© 2017 National Association of Social Workers.)

Background: In light of the current modifications presented in the diagnostic criteria of posttraumatic stress disorder (PTSD) in the DSM 5, this study aimed at revalidating well-known PTSD risk factors, including gender, peritraumatic dissociation, social support, level of threat, and trait tendency for forgiveness., Method: Five hundred and one Israeli civilians were assessed during real-time exposure to missile and rocket fire at the eruption of the Gaza war. Assessments took place approximately one to 2 weeks after the beginning of this military operation, relying on web administration of the study, which allowed simultaneous data collection from respondents in the three regions in Israel that were under attack., Results: A structural equation model design revealed that higher levels of forgiveness toward situations were associated with fewer PTSD symptoms, whereas peritraumatic dissociation and high levels of objective and subjective threat were positively associated with PTSD symptoms. Additionally, females were at higher risk for PTSD symptoms than males., Conclusions: The findings of this study provide further evidence for the importance of directing preventive attention to those vulnerable to the development of elevated levels of PTSD symptoms. Theoretical and clinical implications of the findings are discussed.

This study examined the role played by indicators of premorbid personality in the development of posttraumatic stress symptoms (PTSS). The initial sample consisted of 185 undergraduate students who had coincidentally been evaluated for their PTSS levels 2 weeks prior to a terrorist explosion. A week after the explosion, the sample was assessed to determine the extent of actual exposure. Of the initial 185 students, 81 reported being exposed and thus constituted the final cohort. They were reevaluated at 1 month after the explosion. Both assessments included personality and PTSS evaluation. Data analyses revealed five positive predictors of PTSS levels: high pre-attack PTSS levels, personal exposure, significant other's exposure, indirect exposure, and high premorbid levels on the harm avoidance personality dimension.

Objective: The present study examined prospectively the relationship between memory of the traumatic event and subsequent development of posttraumatic stress disorder (PTSD). More specifically, the aims of this study were to 1) investigate the possibility that lack of memory of the traumatic event might be a protective factor; 2) assess whether memory of the traumatic event equally affects the three symptom clusters of PTSD: reexperiencing, avoidance, and hyperarousal; and 3) explore the predictive value of memory of the traumatic event for the development of subsequent PTSD in the immediate aftermath of the event., Method: One hundred twenty subjects with mild traumatic brain injury who were hospitalized for observation were assessed immediately after the trauma and followed up 1 week, 3 months, and 6 months later. All participants underwent psychiatric evaluation and self-assessment of their memory of the traumatic event., Results: Overall, 17 (14%) of the participants met full criteria for PTSD at 6 months. Subjects with memory of the traumatic event were significantly more likely to develop PTSD than those without memory of the traumatic event; the difference between the groups resulted primarily from the reexperiencing cluster. Logistic regression analysis revealed that memory of the traumatic event within the first 24 hours is a strong predictor of PTSD 6 months after the event., Conclusions: Our study indicated that memory of a traumatic event is a strong predictor and a potential risk factor for subsequent development of PTSD. Future studies are needed to show whether these findings can be generalized to other traumatic conditions.

The underlying question of the present study was whether suicide attempt and suicidal ideation are derived from the same personality dynamic among psychiatric outpatients. Participants included 80 males and females with a history of suicide attempt and 92 without such a history. All participants were evaluated individually with the Tridimensional Personality Questionnaire (TPQ; Cloninger, 1987) and with the Beck Suicide Inventory (BSI; Beck & Steer, 1991). Based on the evaluation results, those without a history of suicide attempt were divided into two groups: high and low suicidal ideations. Data analyses revealed that suicide attempt and suicidal ideation may emerge from distinct, yet somewhat overlapping, personality dynamics.
