Prevalence of post-traumatic stress disorder among Palestinian children and adolescents exposed to political violence: A systematic review and meta-analysis.

OBJECTIVE: We undertook a systematic review of the literature to explore the prevalence of post-traumatic stress disorder (PTSD) in Palestinian children and adolescents exposed to political violence. This is the first systematic review and meta-analysis of the prevalence of PTSD in this population. METHODS: PubMed, Embase, PsycInfo, Google Scholar and Cochrane library were searched until June 2020. To estimate the prevalence of PTSD, sub-group and meta-analysis were conducted. RESULTS: The search resulted in 2786 studies, of which 28 articles representing 32 samples with a total of 15,121 participants from Gaza Strip and West Bank met either the DSM-4 or DSM-5 criteria and were included. The pooled prevalence of PTSD was 36% (95% CI 30-41%; I2 98.6%) and ranged from 6% to 70%. Sub-group analysis showed that the PTSD prevalence did not differ according to region (West Bank, Gaza Strip) and tended to decrease after including only studies using a representative sample (p<0.001), and among those with low risk of bias (p<0.001). Visual inspection of the included studies revealed significant discrepancies in study design and assessment measures. CONCLUSION: We identified high prevalence of PTSD among Palestinian children and adolescents exposed to political violence. However, the pooled results should be interpreted with caution, due to the high heterogeneity and risk of bias in the included studies. These limitations also reflect the challenge in conceptualizing and measuring PTSD in the Palestinian context with a background of continuous and cumulative trauma. Understanding the contextual factors and developing locally adapted survey measures are of relevance to future research, public health planning, and the provision of mental healthcare in Palestine.

Psychological effects of bed bug attacks (Cimex lectularius L.).

BACKGROUND: In some individuals, psychological sequelae resulting from bed bug biting events include nightmares, flashbacks, hypervigilance (to keep the bugs away), insomnia, anxiety, avoidance behaviors, and personal dysfunction. These symptoms are suggestive of posttraumatic stress disorder (PTSD). METHODS: We used a previously published PTSD checklist to analyze online blogs and other Internet sites where bed bug postings occur to assess postings for evidence of emotional trauma. RESULTS: One hundred thirty-five postings were read and analyzed, and 110 (81%) of those postings reported psychological effects from bed bug infestations. Scoring with the PTSD checklist revealed a range of 0-52 (mean 13.25; SD 9.38); one met the criteria (≥50) considered positive for PTSD. CONCLUSIONS: Based upon our survey of online postings concerning such effects, an as-yet-to-be-determined proportion of individuals who experience bed bug bites develop moderate-to-severe negative emotional symptoms after infestations. These individuals should be identified in the course of their interactions with health professionals so that appropriate mental health care may be provided.

Violence against nurses and its impact on stress and productivity.

The purpose of this study was to examine how violence from patients and visitors is related to emergency department (ED) nurses' work productivity and symptoms of post-traumatic stress disorder (PTSD). Researchers have found ED nurses experience a high prevalence of physical assaults from patients and visitors. Yet, there is little research which examines the effect violent events have on nurses' productivity, particularly their ability to provide safe and compassionate patient care. A cross-sectional design was used to gather data from ED nurses who are members of the Emergency Nurses Association in the United States. Participants were asked to complete the Impact of Events Scale-Revised and Healthcare Productivity Survey in relation to a stressful violent event. Ninety-four percent of nurses experienced at least one posttraumatic stress disorder symptom after a violent event, with 17% having scores high enough to be considered probable for PTSD. In addition, there were significant indirect relationships between stress symptoms and work productivity. Workplace violence is a significant stressor for ED nurses. Results also indicate violence has an impact on the care ED nurses provide. Interventions are needed to prevent the violence and to provide care to the ED nurse after an event.

Neural responses to masked fear faces: sex differences and trauma exposure in posttraumatic stress disorder.

Although women have a greater propensity than men to develop posttraumatic stress disorder (PTSD) following trauma, sex differences in neural activations to threat have received little investigation. This study tested the prediction that trauma would heighten activity in automatic fear-processing networks to a greater extent in women than in men. Functional magnetic resonance imaging (fMRI) data were recorded in 23 participants with PTSD (13 women, 10 men), 21 trauma-exposed controls (9 women, 12 men), and 42 non-trauma-exposed controls (22 women, 20 men) while they viewed masked facial expressions of fear. Exposure to trauma was associated with enhanced brainstem activity to fear in women, regardless of the presence of PTSD, but in men, it was associated only with the development of PTSD. Men with PTSD displayed greater hippocampal activity to fear than did women. Both men and women with PTSD showed enhanced amygdala activity to fear relative to controls. The authors conclude that greater brainstem activation to threat stimuli may contribute to the greater prevalence of PTSD in women, and greater hippocampal activation in men may subserve an enhanced capacity for contextualizing fear-related stimuli.

A school-based, teacher-mediated prevention program (ERASE-Stress) for reducing terror-related traumatic reactions in Israeli youth: a quasi-randomized controlled trial.

BACKGROUND: Since September 2000 Israeli children have been exposed to a large number of terrorist attacks. A universal, school-based intervention for dealing with the threat of terrorism as well as with terror-related symptoms, ERASE-Stress (ES), was evaluated in a male religious middle school in southern Israel. The program was administered by the homeroom teachers as part of the school curriculum. It consists of 12 classroom sessions each lasting 90 minutes, and included psycho-educational material, skill training and resiliency strategies delivered to the students by homeroom teachers. METHODS: One hundred and fourteen 7th and 8th grade students were randomly assigned to the ES intervention or were part of a waiting list (WL). They were assessed on measures of posttraumatic symptomatology, depression, somatic symptoms and functional problems before and 3 months after the intervention or the WL period. RESULTS: Three months after the program ended, students in the experimental group showed significant reduction in all measures compared to the waiting-list control group. CONCLUSIONS: The ERASE-Stress program may help students suffering from terror-related posttraumatic symptoms and mitigate the negative effects of future traumatic experiences. Furthermore, a school-based universal program such as the ERASE-Stress may potentially serve as an important and effective component of a community mental health policy for communities affected by terrorism.

Response to trauma in Haitian youth at risk.

In order to characterize undesirable behavior (drug use, fighting, criminal activity) among Haitian youth at risk and determine the relationship between traumatic experience and that kind of behavior, investigators recruited 292 Haitian youths via networks of informal social relations in two zones of Miami/Dade County strongly identified with Haitian ethnicity. Each recruit responded to an interview schedule eliciting sociodemographic information and self-reported activities, including involvement in youth-dominated groups. They also reported traumatic experience. Clinicians administered CAPS to a subset of those respondents who self reported traumatic experience. Staff ethnographers selected respondents for in-depth interviews and family studies to provide contextual depth for findings of the interview schedule and the CAPS assessments. Although traumatic experience may still play a role in mental health outcomes among children, childhood victimization among Haitian children does not appear to be related to the drug use and undesirable behaviors associated with unsupervised youth, including formation of gangs.

[Prospective study of post-traumatic stress in victims of terrorist attacks]. / Etude prospective de l'état de stress post-traumatique parmi des victimes d'un attentat terroriste.

In 1995-96 several terrorist attacks struck Paris. After that, the French government decided to optimize the service claimed to treat psychological repercussions of attacks victims. For this reason we need to better understand the psychopathology developing after these traumatic events in order to adjust the various steps of the treatment. In December 1996, a terrorist attack occurred in a Paris subway. Medical and medico-psychological teams intervened immediately on the site to help victims. Among 115 victims, 4 persons died and 35 were seriously injured. The aim of our study was to evaluate the psychological impact among a population of terrorist attacks victims by a prospective study and to identify predictive factors of posttraumatic stress disorder (PTSD). We evaluated PTSD rates at 6 and 18 months, the relationship between coping style and PTSD, and whether PTSD increased health care utilization. Two follow up evaluations were performed in the 6th and 7th month respectively, by means of self-questionnaires sent by mail. Among 115 victims of the bombing attack occurred in December 1996, the 111 survivors were asked to participate to the study. The subjects who accepted and could use French questionnaires were considered eligible for the inclusion: the main criteria of the Watson's PTSD Inventory for the specific post-traumatic symptoms were used; the Goldberg's General Health Questionnaire was used to measure the general psychopathology; to identify coping styles we used the questionnaire "Ways of Coping Check List" of Vitaliano at 6 months and the "Coping Inventory for Stressful Situations (CISS)" by Endler at 18 months; a small questionnaire was proposed to evaluate injuries, hospitalization and specific treatment immediately or after the event. Among 70 subjects who accepted to participate, 56 (33 females) could be evaluated at 6 months and 32 (14 females) subjects at 18th months. The mean age at 6 months was 38.4 years: 41% of participants met PTSD criteria at 6 months, 34.4% still had PTSD at 18 months; at 18th months, 50% subjects presented GHQ scores higher than 3, corresponding to the cut-off revealing mental suffering; people hospitalized more than two days immediately after the event presented significantly lower PTSD scores at 6 months. General characteristics of risks factors for PTSD were: at 6 and 18 months, women and younger people presented significantly higher PTSD scores; for the CISS at 18 months Emotion-oriented coping correlated significantly with PTSD (r = 0.49, p = 0.007), while task-oriented coping and PTSD correlated negatively (r = -0.39; p = 0.04). Avoidance coping's styles were not correlated with PTSD. About predictive factors: the GHQ-12 and PTSD-I scores at 6 months were significantly correlated with PTSD-I scores at 18 months (respectively r = 0.73, p = 0.018 and r = 0.75, p = 0.0029); by a multiple regression we observed that PTSD-I score at 6 months predicted the PTSD-I score at 18 months, adjusted on sex and age. The others characteristics at 18 months were: medication use increased significantly at 18 months; people who lived another traumatic event since December 1996 presented a 18 month PTSD score higher than the other victims. In spite of the small size of this sample, the principal interest of this study is the prospective data in a population exposed by the same traumatic event. We note the high score of PTSD at 18 months. Terrorism exposure resulted in persisting PTSD in a significant proportion of victims; this was related to coping style. Moreover PTSD increased health care utilization. We discuss these results comparing with other similar populations in France, Israel and USA. We discuss overall the role of coping styles during the time after an attack; we insist on considering this aspect in the therapeutic strategies. These data contribute to inform that people with a high PTSD score at 6 months presented a high risk to suffer PTSD at 18 months. These results underline the importance of early diagnosis to propose early medical and psychological help to the victims.
