Pedopsychiatric and Multidisciplinary Research Devoted to Children Exposed to the Attack in Nice on July 14, 2016

Study Overview
=================
Brief Summary
-----------------
On July 14, 2016, in Nice, children and their families were attacked by the organization EI. In Nice, 86 deaths, including 10 children, the youngest at 4, were recorded. A number of children, still difficult to assess exactly but over 100, was bereaved. After a traumatic event, multiple clinical consequences may appear in children. Among these consequences, the most common is Post-Traumatic Stress Disorder (PTSD). The aim of the study is to characterize the psycho-social factors of risk and / or protection interfering in the children's future, following the mass trauma of 14 July 2016 in Nice on a sample of pediatric population exposed in comparison of children controls. Ancillary study, entilted The Physalis Child, prospectively observe the presence or not of non-psychotic acousto-verbal hallucinations (AVH) in the population with PTSD from the Program 14-7. The main objective of this ancillary study will be to identify factors of social and emotional cognition linked to the presence of non-psychotic HAV within the cohort of children exposed to the mass trauma of July 14, 2016 in Nice but also to any type of individual trauma. Ancillary study, entilted trail of the 14 July attack, prospectively observe the risk of traumatic reactivation.

Detailed Description
-----------------
On July 14, 2016, in Nice, children and their families were attacked by the organization EI. This is the second time in our country that children are victims of this organization after the attack on the school Ozar Hotarah in March 2012 in Toulouse where four children were killed touching end. In Nice, 86 deaths, including 10 children, the youngest at 4, were recorded. A number of children, still difficult to assess exactly but over 100, was bereaved. After a traumatic event, multiple clinical consequences may appear in children. Among these consequences, the most common is Post-Traumatic Stress Disorder (PTSD). This pathology includes 4 main symptoms: the reviviscences of the event, avoidance behaviors, alterations of cognition and mood and neurovegetative overactivation. In addition, PTSD contributes to the development of many other mental disorders. It is estimated that 75% of adolescents or children having a comorbid disorder with PTSD. In the literature, the main comorbidities identified in pediatric populations are: anxiety disorders, Attention Deficit Hyperactivity Disorder (ADHD) and depression. There is no recommendation as to the therapeutics to be used in psychotraumatism in pediatric population. Epidemiological studies conducted on the consequences of trauma reveal a high variability in the development of psychopathologies. 6 to 20% of exposed children would develop PTSD after a potentially traumatic situation. Several factors can explain the heterogeneity of the results, including the age, the type of trauma experienced, the violence suffered during this trauma. In Nice, to date, more than 2200 children have consulted: 700 children between July 14 and July 28, 2016, 1100 children were seen between August and December, and about 400 since the creation of the Post Traumatic Pediatric Intersectoral Assessment Center (CE2P), in January 2017. The aim of the study is to characterize the psycho-social factors of risk and / or protection interfering in the children's future, following the mass trauma of 14 July 2016 in Nice on a sample of pediatric population exposed in comparison of children controls. Non-psychotic hallucinations represent a significant symptomatology in child psychiatry (1) and remain clinical question. The results of our previous study the physalis child showed a significant correlation between the persistence of non-psychotic acousto-verbal hallucinations (AVH) and the presence of negative emotions, linked to post traumatic stress disorder (PTSD). It seems important to understand the link between trauma and the presence of non-psychotic AVH in children as the literature shows the risk of progression to psychosis when these AVH persist.The interest of the ancllary study of the physalis child would be to prospectively observe the presence or not of non-psychotic AVH in the population with PTSD from the Program 14-7. The question would then be: Why in two subjects diagnosed with PTSD, one has non-psychotic HAV and the other does not? The main objective of this ancillary study will be to identify factors of social and emotional cognition linked to the presence of non-psychotic HAV within the cohort of children exposed to the mass trauma of July 14, 2016 in Nice but also to any type of individual trauma. The impending opening of the trial of the 14 July attack, the conduct and the media coverage associated with the trial are all factors that could be distressing for the children and families exposed to the attack in Nice. Re-exposure to testimonials and certain images can increase the risk of traumatic reactivation with a return of suppressed fears and the symptoms associated. Some factors have been identified as protective: social and family support, cognitive functioning, the presence of residual symptoms or the quality of sleep. Therefore, an assessment of these factors before and after the opening of the trial would identify children and families with traumatic reactivation, as well as identify protective or risk factors for relapse of traumatic symptoms

| impact of trial of the attack July 14th on Parenthood | Parenthood assessment will be offered to parents of children included in the arm impacted by attack The Parenting Sense of Competence (PSOC) questionnaire is a widely used scale to assess and measure parenting abilities perceived by parents with two subscales: competence/knowledge and appreciation/comfort. The PSOC is a scale with a score ranging from 17 to 102. The higher the score, the more the parent feels a sense of high parenting competence. To demonstrate a minimum difference of 20 points on this questionnaire before and after the trial, with a standard deviation of 20, the number of participants required is 44 Two visits will be realized: a first in the month preceding the start of the trial (baseline) and a second in the month following the end of the trial. | baseline and month9 | 
| impact of trial of the attack July 14th on Cognitive alterations | Evaluation of cognitive alterations, in particular memory disorders and executive functions, will be aimed at children aged 0 to 6 at the time of the July 14, 2016 attack Episodic memory will be assessed using Grober and Buschke (Grober and Buschke, 1988). This test includes 16 items to memorize belonging to 16 different semantic categories. The duration of this test is approximately 20 minutes. This test starts with a control phase of the semantic encoding of words with an immediate cued recall, 3 free and cued recall phases with a 20-second interferential task, a recognition phase and finally a free and deferred cued recall phase to test learning. Previous studies using this test show a mean difference of 2 points between the control groups and the experimental groups. The evaluation of the cognitive alterations will include two stages: a first in the month preceding the start of the trial (baseline) and a second in the month following the end of the trial | baseline and month 6 | 
| impact of trial of the attack July 14th on schooling | Evaluation of the impact of schooling will focus on middle and high school students, using Pronote software and included in the arm impacted by attack . In order to test the impact of the trial on children's education, several data will be requested from parents. Using the Pronote software, they will be able to communicate to us the number of absences of the child, the number of exclusions and hours of detention of the child, as well as the school reports of the child to obtain the effective grades of children and adolescents. This data will be collected for the 2021-2022 school year (3 terms of the previous school year) and for the 2022-2023 school year (3 terms of the current year). | 2 years from baseline | 
| impact of trial of the attack July 14th on Sleep disorders and associated somatizations | Evaluation of sleep disorders and associated somatizations will be offered to adolescents in the 14-7 cohort, are children aged 7 to 12 at the time of the attack. The screening scale for sleep disorders in children aged 4 to 16 years by Bruni et al. 1996 . This questionnaire includes an overall sleep quality score, but also sub-indices evaluating insomnia, parasomnia, respiratory problems, non-restorative sleep and excessive daytime sleepiness. The threshold score is 39 and an average score around 25 for the control population. This questionnaire will be carried out during the month preceding the opening of the trial (baseline), then every month, until the end of the trial. From baseline to the end of trial, participants will receive a connected watches to continuously record sleep quality and daytime activity. A questionnaire on Post Traumatic Stress Disorder (PTSD) symptoms will also be completed by the participants at baseline and at the end of trial. | baseline and month 6 |
