Risk Factors for Depression Among Civilians After the 9/11 World Trade Center Terrorist Attacks: A Systematic Review and Meta-Analysis

The impact of potentially morally injurious experience of betrayal on PTSD and depression following the October 7th terror attack

With about 1200 individuals murdered, the massacre of October 7th was one of the deadliest terrorist attacks in modern history. The mental health consequences of terrorist attacks have been documented. However, little is known of the impact of the potentially morally injurious experience (PMIE) of betrayal--in which individuals feel betrayed by leaders they once trusted--on levels of psychological burden in the aftermath of such an attack. In this national prospective cohort study, we examined to what extent the PMIE of betrayal exacerbates the risk for posttraumatic stress disorder (PTSD) and depression in the wake of the October 7th terrorist attack. A representative sample of 710 Israeli adults (362 female, 51.1%), Jews (557, 79.9%) and Arabs (153, 20.1%), aged 18-85 (M = 41.01, SD = 13.72) completed validated self-report questionnaires assessing PTSD, depression, and PMIE-betrayal at two timepoints: T1, in August 2023 (6-7 weeks before the attack) and T2, in November 2023 (5-6 weeks after the attack). In two hierarchical logistic regressions, we found that experience of PMIE-betrayal predicted diagnoses of both PTSD (OR 1.92, 95% CI 1.26-2.92) and depression (OR 2.03, 95% CI 1.37-3.01) at T2, beyond probable PTSD/depression at T1 and demographic and trauma-related variables. Moreover, in two repeated-measure analyses predicting PTSD/depression symptoms, we found significant interactions between PTSD/depression trajectories and PMIE-betrayal, meaning that the increase of PTSD/depression symptoms was significantly higher among participants experiencing betrayal in the context of the attack. Our study highlights the impact of PMIE of betrayal on the dramatic increase in psychopathology following the October 7th terror attack on Israel's population. Clinicians treating individuals coping with PTSD and depression should attend to their patients' possible exposure to betrayal following the attack. Moreover, national leaders and policymakers should take significant steps to repair the public's betrayal experience.

Trauma Matters: Integrating Genetic and Environmental Components of PTSD

Trauma is ubiquitous, but only a subset of those who experience trauma will develop posttraumatic stress disorder (PTSD). In this review, it is argued that to determine who is at risk of developing PTSD, it is critical to examine the genetic etiology of the disorder and individual trauma profiles of those who are susceptible. First, the state of current PTSD genetic research is described, with a particular focus on studies that present evidence for trauma type specificity, or for differential genetic etiology according to gender or race. Next, approaches that leverage non-traditional phenotyping approaches are reviewed to identify PTSD-associated variants and biology, and the relative advantages and limitations inherent in these studies are reflected on. Finally, it is discussed how trauma might influence the heritability of PTSD, through type, risk factors, genetics, and associations with PTSD symptomology.

Liposaccharide-induced sustained mild inflammation fragments social behavior and alters basolateral amygdala activity

RATIONALE

Conditions with sustained low-grade inflammation have high comorbidity with depression and anxiety and are associated with social withdrawal. The basolateral amygdala (BLA) is critical for affective and social behaviors and is sensitive to inflammatory challenges. Large systemic doses of lipopolysaccharide (LPS) initiate peripheral inflammation, increase BLA neuronal activity, and disrupt social and affective measures in rodents. However, LPS doses commonly used in behavioral studies are high enough to evoke sickness syndrome, which can confound interpretation of amygdala-associated behaviors.

OBJECTIVES AND METHODS

The objectives of this study were to find a LPS dose that triggers mild peripheral inflammation but not observable sickness syndrome in adult male rats, to test the effects of sustained mild inflammation on BLA and social behaviors. To accomplish this, we administered single doses of LPS (0-100 μg/kg, intraperitoneally) and measured open field behavior, or repeated LPS (5 μg/kg, 3 consecutive days), and measured BLA neuronal firing, social interaction, and elevated plus maze behavior.

RESULTS

Repeated low-dose LPS decreased BLA neuron firing rate but increased the total number of active BLA neurons. Repeated low-dose LPS also caused early disengagement during social bouts and less anogenital investigation and an overall pattern of heightened social caution associated with reduced gain of social familiarity over the course of a social session.

CONCLUSIONS

These results provide evidence for parallel shifts in social interaction and amygdala activity caused by prolonged mild inflammation. This effect of inflammation may contribute to social symptoms associated with comorbid depression and chronic inflammatory conditions.

Environmental Factors in the Etiology of Mental Disorders in the Czech Republic

BACKGROUND

Both genetic and environmental factors are important in etiology of mental disorders. Calculating polyenviromic risk/protective scores provides an updated perspective in research on the environmental causes of psychiatric disorders. We aimed to compare environmental risk and protective factors in patients with psychosis or a mood disorder (PSYCH+MOOD) and those with an anxiety disorder (ANX).

METHODS

We administered the internationally accepted questionnaire from the EUropean Network of National Schizophrenia Networks Studying Gene-Environment Interactions (EU-GEI) study, enriched with mood and anxiety disorder-relevant measures, to patients at two large university hospitals in the Czech Republic.

RESULTS

Ninety-four PSYCH+MOOD patients (average age 42.5 years; 46 males) and 52 ANX patients (average age 47.2 years; 17 males) participated. Neither polyenviromic risk score nor polyenviromic protective score differed significantly between PSYCH+MOOD and ANX groups (p = 0.149; p = 0.466, respectively).

CONCLUSION

Scientific validity of the polyenviromic risk/protective score construct must still be demonstrated in large psychiatric samples, ideally in prospective studies. Nevertheless, researchers have already started to investigate environmental factors in the etiology of mental disorders in their complexity, similarly to polygenic risk scores.

Support over Social Media among Socially Isolated Sexual and Gender Minority Youth in Rural U.S. during the COVID-19 Pandemic: Opportunities for Intervention Research

Sexual and gender minority (SGM) rural adolescents are at risk for higher levels of social isolation, a well-known risk factor for depression and other negative health outcomes. We qualitatively examined how rural SGM youth seek emotional and informational support, which are protective factors for social isolation on social media (SM) regarding their SGM identity, and determined which SM platforms and tools are most effective in providing support. We conducted semistructured online interviews with rural SGM teens who screened positive for social isolation in spring 2020 and used a thematic analysis approach to analyze the data. Sixteen youths participated in interviews. Themes included seeking emotional support through SM groups and communities, seeking emotional support in designated online SGM spaces, using SM feeds for informational support, and disclosing SGM identity differentially across platforms. SM-based interventions could be leveraged to provide emotional and informational support for rural SGM youth across specific SM platforms and consider whether they are providing emotional or information support. Interventions focused on informational support may best be used on content-based platforms. Those designed to combat social isolation and connect marginalized SGM youths to similar others might benefit from community and forum-based platforms.

Examining Social Media Experiences and Attitudes Toward Technology-Based Interventions for Reducing Social Isolation Among LGBTQ Youth Living in Rural United States: An Online Qualitative Study

Purpose

Lesbian, gay, bisexual, transgender, and queer (LGBTQ) youth living in rural areas who feel isolated are at high risk of depression and suicidality. Given the lack of support in their offline communities, many rural-living LGBTQ youth turn to social media for social support. In this qualitative study, we examined rural LGBTQ youth's social media experiences and attitudes toward technology-based interventions for reducing perceived isolation.

Method

In Spring 2020, we conducted online interviews with LGBTQ youth aged 14-19, living in rural areas of the United States, who screened positive for perceived social isolation (n = 20; 11 cisgender sexual minority, 9 transgender). Interviews examined (1) supportive social media experiences, (2) personal strategies to improve social media experiences, and (3) perspective on potential digital intervention delivery modalities. Data were analyzed using thematic analysis.

Findings

Related to supportive content and interactions, themes included (1) positive representation of and connecting with LGBTQ groups on social media are important; (2) content from people with shared experience feels supportive, and (3) lack of feedback to one's experiences is isolating. Regarding personal strategies to improve social media experiences, themes were (1) selecting platforms to connect with different audiences helps make for a more enjoyable social media experience, and (2) several social media platform features can help make for a safer social media experience. Youth discussed advantages and disadvantages of intervention delivery via a mobile app, social media pages or groups, conversational agents (chatbots), and a dedicated website.

Conclusion

Viewing positive representation of and connecting with LGBTQ groups, content from people shared experiences, and utilizing a wide array of platform features to increase the likelihood of positive connections are key to a positive social media experience among this group. Combining delivery modalities is key to engaging rural-living LGBTQ youth in digitally delivered support interventions to reduce perceived isolation. Our results inform future intervention research and conversations about social determinants of health between providers and rural LGBTQ patients.

Child Disruptions, Remote Learning, and Parent Mental Health during the COVID-19 Pandemic

New York City (NYC) was an epicenter of the COVID-19 pandemic, which resulted in broad economic, social, and emotional consequences in the lives of individuals. The current study examined associations between pandemic-related stressors and adverse mental health symptoms among NYC parents/caregivers. Community-based participatory research was used to develop a survey, and logistic regression models were utilized to assess associations between factors including disruptions in child routines and remote learning, and parent-reported symptoms of stress, anxiety, depression, and post-traumatic stress disorder (PTSD). Some 91.0% of parents reported stress and 41.2, 26.6, and 33.7% reported symptoms of anxiety, depression, and PTSD, respectively. Most parents (87.6%) reported cancellation of at least one child activity. Of the parents, 60.3% reported that their children participated in remote learning and the majority (70.3%) reported feeling overwhelmed by it. Having more cancelled child activities was associated with higher odds of reported mental health symptoms, with not being able to play outside associated with higher odds of anxiety (1.80 (1.26, 2.58), p = 0.001), depression (1.93 (1.29, 2.91), p = 0.002), PTSD (1.64 (1.13, 2.39), p = 0.009), and stress (2.34 (1.27, 4.44), p = 0.008). Feeling overwhelmed by remote learning was also associated with higher odds of all four outcomes. Pre-existing mental illness, lower resilience scores, and lower socioeconomic status emerged as additional factors associated with symptoms of mental illness. These findings highlight the importance of resources to minimize adverse psychological effects among vulnerable families.

Social Connection as a Public Health Issue: The Evidence and a Systemic Framework for Prioritizing the "Social" in Social Determinants of Health

There is growing interest in and renewed support for prioritizing social factors in public health both in the USA and globally. While there are multiple widely recognized social determinants of health, indicators of social connectedness (e.g., social capital, social support, social isolation, loneliness) are often noticeably absent from the discourse. This article provides an organizing framework for conceptualizing social connection and summarizes the cumulative evidence supporting its relevance for health, including epidemiological associations, pathways, and biological mechanisms. This evidence points to several implications for prioritizing social connection within solutions across sectors, where public health work, initiatives, and research play a key role in addressing gaps. Therefore, this review proposes a systemic framework for cross-sector action to identify missed opportunities and guide future investigation, intervention, practice, and policy on promoting social connection and health for all. Expected final online publication date for the Annual Review of Public Health, Volume 43 is April 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Social Connectivity During the COVID-19 Pandemic: Disparities among Medicare Beneficiaries

Purpose

Social connections are essential for health and well-being at all ages and may be especially important for promoting health in later life. Maintaining social connections, however, became increasingly difficult during the COVID-19 pandemic when stay-at-home orders were enacted, and social distancing became necessary. This study examines the social connectivity among Medicare beneficiaries during the COVID-19 pandemic highlighting the importance technological availability, income, and race.

Methods

Data from the 2020 Medicare Beneficiaries Survey COVID supplement was used to evaluate social connectedness during the spring and fall of 2020. Binomial logistic regression evaluated the relationship between feelings of social connectedness and race/ethnicity, urban status of residence, income, availability of household technologies, internet access, and chronic conditions.

Results

Lower social connectivity is significantly correlated with race and income. Blacks had a nearly 30% higher likelihood of feeling socially disconnected than other racial groups. Individuals with chronic conditions, particularly cancer, were significantly more likely to feel socially disconnected. Internet access and the availability of technological devices decreased the odds of feeling socially disconnected by 20% and 15% respectively.

Conclusion

The COVID-19 pandemic decreased the social connectedness of many vulnerable groups specifically Blacks, those living with chronic conditions, and individuals with limited access to technology. While it is outside the scope of the current study, additional research is needed to determine how to address the social and psychological impacts of the COVID-19 pandemic among elderly Americans.

Longitudinal Mental Health Effects of the 2016 Terrorist Attack in Berlin on Various Occupational Groups of Emergency Service Personnel

Emergency service personnel who respond to terrorist attacks may experience persistent stress following the event. This occupational stress must be examined in order to develop occupation-specific response preparation and follow-up measures. An explorative pilot study examined the occupational stress-related effects of the 2016 terrorist attack on Breitscheidplatz in Berlin on emergency service personnel. The present study examines whether the results of the pilot study can be replicated and whether the effects changed after 2 years. The participants were 60 emergency personnel (including 11 police officers and 24 firefighters) who were deployed to the attack, and a control group of 60 personnel (including 37 police officers and 21 firefighters) who were not deployed. Data on stress, quality of life, and current mental state were gathered 3 to 4 months after the attack and 18 to 21 months after the first survey. The data showed that police officers who responded to the attack had significantly higher levels of aggression and hostility at both time points, and firefighters had significantly lower levels of environmental quality of life at both time points. Quality of life in terms of physical health for firefighters could not be replicated. Due to the different types of stress experienced by emergency service personnel, a differentiated approach is necessary. More specific preparation and follow-up measures are necessary to counteract persistent stress. Further research in this area could lead to specific predeployment and postdeployment training measures.

Potential impact of physical distancing on physical and mental health: a rapid narrative umbrella review of meta-analyses on the link between social connection and health

BACKGROUND

The imperative for physical distancing (mostly referred to as social distancing) during COVID-19 pandemic may deteriorate physical and mental health. We aimed at summarising the strength of evidence in the published literature on the association of physical and mental health with social connection via social isolation, living alone and loneliness.

METHODS

We conducted a systematic search in April 2020 to identify meta-analyses using the Medline, PsycINFO and Web of Science databases. The search strategy included terms of social isolation, loneliness, living alone and meta-analysis. Eligible meta-analyses needed to report any sort of association between an indicator of social connection and any physical or mental health outcome. The findings were summarised in a narrative synthesis.

RESULTS

Twenty-five meta-analyses met our criteria, of which 10 focused on physical health and 15 on mental health outcomes. The results suggest that lack of social connection is associated with chronic physical symptoms, frailty, coronary heart disease, malnutrition, hospital readmission, reduced vaccine uptake, early mortality, depression, social anxiety, psychosis, cognitive impairment in later life and suicidal ideation.

CONCLUSIONS

The existing evidence clearly indicates that social connection is associated with a range of poor physical and mental health outcomes. A potential negative impact on these outcomes needs to be considered in future decisions on physical distancing measures.
