Childhood trauma as a predictor of changes in sleep quality in American Indian adults during the COVID-19 pandemic

Childhood unpredictability and sleep quality in adulthood: the mediating roles of life history strategy and perceived stress

Background

Early environmental risk have been found to be related to lifelong health. However, the impact of childhood unpredictability, a type of early environmental risk, on health, especially on sleep quality in adulthood, has not been adequately studied. The present study aimed to examine the relationship between childhood unpredictability and sleep quality in adulthood and to explore the possible mediating roles of life history strategy and perceived stress.

Methods

A cross-sectional study was conducted on 472 participants from a university in Zhejiang Province, China. The questionnaire inquired about demography, childhood unpredictability, life history strategy (Mini-K), perceived stress (14-item Perceived Stress Scale), and Sleep Quality (Pittsburgh Global Sleep Quality Index).

Results

Higher childhood unpredictability was significantly associated with worse sleep quality in adulthood. Moreover, the link between higher childhood unpredictability and worse sleep quality in adulthood was explained by the chain mediation of life history strategy and perceived stress.

Conclusion

In line with the life history theory, individuals who have experienced higher unpredictability in childhood tend to develop a faster life history strategy and become more sensitive to stress in adulthood, and subsequently suffer a decrease in sleep quality.

Discovery of depression-associated factors among childhood trauma victims from a large sample size: Using machine learning and network analysis

BACKGROUND

Experiences of childhood trauma (CT) would lead to serious mental problems, especially depression. Therefore, it becomes crucial to identify influential factors related to depression and explore their associations. The objectives were to 1) identify critical depression-related factors using the extreme gradient boosting (XGBoost) method from a large-scale survey data; 2) explore associations between these factors for targeted interventions and treatments.

METHODS

A large-scale epidemiological study covering 63 universities was conducted in Jilin Province, China. The XGBoost model was trained and tested to classify young adults with CT experiences who had or did not have depression (N = 27,671). The essential factors were selected by SHapley Additive exPlanations (SHAP) value. Multiple logistic regression analyses were conducted for validation. The associations between these depression-related factors were further explored using network analysis.

RESULTS

The XGBoost model selected the top 10 features associated with depression with satisfactory performance (AUC = 0.91; sensitivity = 0.88 and specificity = 0.76). These factors significantly differed between depression and non-depression groups (p < 0.001). There are strong positive associations between anxiety and obsessive-compulsive disorder (OCD), anxiety and post-traumatic stress disorder (PTSD), social anxiety disorder (SAD) and appearance anxiety, and negative associations between sleep quality and anxiety, sleep quality and PTSD among CT participants with depression.

LIMITATIONS

The cross-sectional design cannot draw causality, and biases in self-report measurements cannot be ignored.

CONCLUSIONS

XGBoost model and network analysis were useful methods for discovering and understanding depression-related factors in this epidemiological study. Moreover, these essential factors could offer insights into future interventions and treatments for depressed young adults with CT experiences.

A review of mental health disparities during COVID-19: Evidence, mechanisms, and policy recommendations for promoting societal resilience

Social and economic inequality are chronic stressors that continually erode the mental and physical health of marginalized groups, undermining overall societal resilience. In this comprehensive review, we synthesize evidence of greater increases in mental health symptoms during the COVID-19 pandemic among socially or economically marginalized groups in the United States, including (a) people who are low income or experiencing homelessness, (b) racial and ethnic minorities, (c) women and lesbian, gay, bisexual, transgender, queer, and questioning (LGBTQ+) communities, (d) immigrants and migrants, (e) children and people with a history of childhood adversity, and (f) the socially isolated and lonely. Based on this evidence, we propose that reducing social and economic inequality would promote population mental health and societal resilience to future crises. Specifically, we propose concrete, actionable recommendations for policy, intervention, and practice that would bolster five "pillars" of societal resilience: (1) economic safety and equity, (2) accessible healthcare, including mental health services, (3) combating racial injustice and promoting respect for diversity, equity, and inclusion, (4) child and family protection services, and (5) social cohesion. Although the recent pandemic exposed and accentuated steep inequalities within our society, efforts to rebuild offer the opportunity to re-envision societal resilience and policy to reduce multiple forms of inequality for our collective benefit.

Childhood trauma and suicide risk in hospitalized patients with schizophrenia: the sequential mediating roles of pandemic related post-traumatic stress symptoms, sleep quality, and psychological distress

Introduction

Stressful global situation due to the COVID-19 pandemic caused a tremendous impact on mental health in hospitalized patients with schizophrenia. The mediating roles of psychological impact related to COVID-19, sleep quality, and psychological distress were investigated in the association between childhood trauma and suicidal risk in hospitalized patients with schizophrenia.

Methods

We analyzed cross-sectional data of 147 patients with schizophrenia and 189 healthy controls (HCs).

Results

Histories of childhood trauma and schizophrenia were good predictors of COVID-19-related psychological impact, global sleep quality, and psychological distress. Moreover, the series mediation model showed that the effect of childhood trauma on suicidal risk in hospitalized patients with schizophrenia was totally sequential mediated by the psychological impact of COVID-19, sleep quality, and psychological distress.

Conclusion

Clinicians need to recognize the increased suicidal risk associated with COVID-19-related psychological distress in schizophrenia patients with a history of childhood trauma.

Adverse childhood experiences and depressive symptoms among adolescents during the COVID-19 pandemic: mediating roles of poor sleep quality and psychological inflexibility

Previous studies have found that adverse childhood experiences can lead to depressive symptoms. But the underlying mechanisms have not been determined. Guided by the 3-P model of insomnia and acceptance and commitment therapy, this study examined the mediating role of poor sleep quality and psychological inflexibility in the relationship between adverse childhood experiences and depressive symptoms during the COVID-19 pandemic. A total of 996 senior high school students in China (Mage = 16.57 years; SD = 1.03) completed the self-report measures of adverse childhood experiences, depressive symptoms, poor sleep quality, and psychological inflexibility. Multiple mediation analysis revealed that adverse childhood experiences were related to depressive symptoms through poor sleep quality and psychological inflexibility, serially. These findings point to potential targets in the prevention of and intervention in adolescent depressive symptoms.

Association between childhood trauma and mental health disorders in adolescents during the second pandemic wave of COVID-19, Chiclayo-Peru

Introduction

The COVID-19 pandemic has significantly affected mental health, with children and adolescents being particularly vulnerable. Evidence on the association between childhood trauma and mental health outcomes in schoolchildren during the pandemic is limited. This study aimed to evaluate this relationship in Chiclayo city, northern Peru, during the second wave of COVID-19.

Methods

A cross-sectional secondary data study was conducted, measuring childhood trauma using the Marshall's Trauma Scale, depressive symptomatology (PHQ-9), and anxiety symptomatology (GAD-7). Additional variables assessed were alcohol use (AUDIT), resilience (abbreviated CD-RISC), and socio-educational data. Prevalence ratios were estimated using generalized linear models.

Results

Among 456 participants, 88.2% were female, with a mean age of 14.5 years (SD: 1.33). Depressive symptomatology prevalence was 76.3% (95%CI: 72.14-80.15) and increased by 23% in schoolchildren with childhood trauma (PR: 1.23; 95%CI: 1.10-1.37). Factors positively associated with depressive symptomatology included increasing age, seeking mental health help during the pandemic, and severe family dysfunction. Anxiety symptomatology prevalence was 62.3% (95%CI: 57.65-66.75) and increased by 55% in schoolchildren with childhood trauma (PR: 1.55; 95%CI: 1.31-1.85). Anxiety symptomatology was positively associated with mild, moderate, and severe family dysfunction.

Conclusion

Schoolchildren exposed to childhood trauma are at increased risk for depressive and anxiety symptoms. Monitoring the impact of the COVID-19 pandemic on adolescent mental health is vital. These findings can assist schools in establishing effective measures to prevent mental health outcomes.

The role of stress phenotypes in understanding childhood adversity as a transdiagnostic risk factor for psychopathology

Childhood adversity is a leading transdiagnostic risk factor for psychopathology, being associated with an estimated 31-62% of childhood-onset disorders and 23-42% of adult-onset disorders (Kessler et al., 2010). Major unresolved theoretical challenges stem from the nonspecific and probabilistic nature of the links between childhood adversity and psychopathology. The links are nonspecific because childhood adversity increases risk, through a range of mechanisms, for diverse forms of psychopathology and are probabilistic because not all individuals exposed to childhood adversity develop psychopathology. In this article, we propose a path forward by focusing on stress phenotypes, defined as biobehavioral patterns activated in response to stressors that can disrupt future functioning when persistent (e.g., reward seeking, social withdrawal, aggression). This review centers on the accumulating evidence that psychopathology appears to be more strongly predicted by behavior and biology during states of stress. Building on this observation, our theoretical framework proposes that we can model pathways from childhood adversity to psychopathology with greater specificity and certainty by understanding stress phenotypes, defined as patterns of behavior and their corresponding biological substrates that are elicited by stressors. This approach aims to advance our conceptualization of mediating pathways from childhood adversity to psychopathology. Understanding stress phenotypes will bring us closer to "precision mental health," a person-centered approach to identifying, preventing, and treating psychopathology.

Psychosocial impacts of the COVID-19 pandemic on women with trauma histories: Study of Women's Health Across the Nation (SWAN)

Older adults, particularly those with trauma histories, may be vulnerable to adverse psychosocial outcomes during the COVID-19 pandemic. We tested associations between prepandemic childhood abuse or intimate partner violence (IPV) and elevated depressive, anxiety, conflict, and sleep symptoms during the pandemic among aging women. Women (N = 582, age: 65-77 years) from three U.S. sites (Pittsburgh, Boston, Newark) of the longitudinal Study of Women's Health Across the Nation (SWAN) reported pandemic-related psychosocial impacts from June 2020-March 2021. Prepandemic childhood abuse; physical/emotional IPV; social functioning; physical comorbidities; and depressive, anxiety, and sleep symptoms were drawn from SWAN assessments between 2009 and 2017. There were no measures of prepandemic conflict. In total, 47.7% and 35.3% of women, respectively, reported childhood abuse or IPV. Using logistic regression models adjusted for age; race/ethnicity; education; site; prepandemic social functioning and physical comorbidities; and, in respective models, prepandemic depressive, anxiety, or sleep symptoms, childhood abuse predicted elevated anxiety symptoms, OR = 1.67, 95% CI [1.10, 2.54]; household conflict, OR = 2.19, 95% CI [1.32, 3.61]; and nonhousehold family conflict, OR = 2.14, 95% CI [1.29, 3.55]. IPV predicted elevated sleep problems, OR = 1.63, 95% CI [1.07, 2.46], and household conflict, OR = 1.96, 95% CI [1.20, 3.21]. No associations emerged for depressive symptoms after adjusting for prepandemic depression. Aging women with interpersonal trauma histories reported worse anxiety, sleep, and conflict during the COVID-19 pandemic than those without. Women's trauma histories and prepandemic symptoms are critical to understanding the psychosocial impacts of the pandemic.

Associations Between Childhood Stressors, COVID-19-Related Anxiety, and Sleep Quality of Adults During the Third Wave of the COVID-19 Pandemic in Israel

PURPOSE

Studies point to a persistent effect of the COVID-19 pandemic on sleep quality and mental health, including anxiety. Exposure to stressors during childhood increases the susceptibility to anxiety in later life. Given the negative effects of anxiety on sleep quality, the present study aimed to examine the associations between various childhood stressors and poor sleep quality of adults during the COVID-19 pandemic, and whether these associations are mediated by COVID-19-related anxiety.

PARTICIPANTS AND METHODS

A total of 586 participants aged 18-40 (mean age 27.53± 6.48 years, 301 females) were recruited to take part in an online survey conducted in Israel between February 7 and 15, 2021, during the third wave of the COVID-19 pandemic. Participants completed questionnaires assessing retrospectively adverse childhood experiences (ACEs), childhood harshness (indexed separately by exposure to morbidity and mortality and low socioeconomic status, SES), and childhood unpredictability. COVID-19-related anxiety was assessed using two items. Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI), and insomnia symptoms with the Insomnia Severity Index (ISI). Participants were asked to complete the ISI concerning two time points: (a) retrospectively, before the COVID-19 outbreak, and (b) currently, during the pandemic.

RESULTS

Path analysis indicated that poor sleep quality (PSQI) was directly and indirectly (through COVID-19-related anxiety) predicted by the number of ACEs and childhood morbidity-mortality exposure, directly predicted by childhood low SES, and indirectly predicted by childhood unpredictability. Insomnia symptoms increase (ISI) was indirectly predicted by the number of ACEs, childhood morbidity-mortality exposure, and childhood unpredictability.

CONCLUSION

ACEs as well as harsh and unpredictable childhood environments are predictive of poorer sleep during the COVID-19 pandemic. COVID-19-related anxiety mediates the effects of childhood stressors (other than low SES) on sleep. These findings may have clinical implications relevant to stressful periods in general.

Covid-19 and changes in sleep health in the Blackfeet Community

We examined changes in psychological outcomes related to the COVID-19 pandemic (ie psychological stress, perceived control, and perceived ability to cope) and changes in sleep health in the American Indian Blackfeet community over 4 months (August 24, 2020-November 30, 2020). American Indian adults residing on the Blackfeet reservation (n = 167) completed measures of perceived control over contracting COVID-19, perceived ability to cope with pandemic stressors, psychological stress linked to the pandemic, and a measure of sleep health each month. Linear-effects mixed models were used to examine changes in our outcomes. Community members who reported more control over contracting the virus had better sleep health relative to those who reported less control (B = 0.72, SE = 0.29, p = 0.015). Further, during months when individuals felt they had more control over contracting the virus compared to their average perceived control levels, they had better sleep health relative to their own average (B = 1.06, SE = 0.13, p < 0.001). Average sleep health was the lowest in October, 2020, the month during which COVID-19 incidence was at its highest on the reservation. Declines in sleep health linked to low levels of control over contracting COVID-19 may exacerbate high incidence of chronic mental and physical health conditions in tribal communities. Interventions which highlight strategies known to reduce risk of contracting the virus, may increase perceived control and sleep health, and thus may improve downstream health outcomes for this at-risk population.

Childhood Trauma and Mental Health Status in General Population: A Series Mediation Examination of Psychological Distress in COVID-19 Pandemic and Global Sleep Quality

Background: Coronavirus-2019 (COVID-19) has been coexisting with humans for almost 2 years, consistently impacting people's daily life, medical environment, and mental health. This study aimed to test the series mediation model triggered by childhood trauma, in which perceived psychological impact of COVID-19 pandemic and sleep quality mediated the path sequentially and led to adverse mental health outcomes. Methods: A cross-sectional design involving 817 participants were enrolled via WeChat online survey. Participants completed questionnaires, including demographic features, the Childhood Trauma Questionnaire, Impact of Event Scale-Revised (IES-R) questionnaire, Pittsburgh Sleep Quality Index (PSQI) questionnaire, and Depression, Anxiety, and Stress Scale (DASS-21). Pearson correlations and hierarchical multiple linear regression were employed to examine the association of childhood trauma and psychological stress of COVID-19, sleep quality, and mental health status. In addition, a series mediate analysis was carried out to examine sequence mediating effects of psychological impact of COVID-19 and sleep quality between childhood trauma and mental health status. Results: The results showed that childhood trauma is positively and significantly related to psychological distress of COVID-19 pandemic, sleep quality, and mental health status (p < 0.05). Hierarchical multiple linear regression analysis shown that demographic features explained 4.4, 2.1, and 4.0% of the total variance in DASS-21, IES-R, and PSQI total scale scores, respectively. Adding childhood trauma significantly increased the model variance of DASS-21 (ΔR ² = 0.129, F = 126.092, p = 0.000), IES-R (ΔR ² = 0.062, F = 54.771, p = 0.000), and PSQI total scale scores (ΔR ² = 0.055, F = 48.733, p = 0.000), respectively. Moreover, the series mediation model showed that the perceived impact of the COVID-19 pandemic and sleep quality were sequential mediators between childhood trauma and mental health status (proportion explained: 49.17%, p < 0.05). Conclusion: Amid the ravages of COVID-19, childhood trauma predicts poor mental health status, in part because of greater psychological impact related to COVID-19 and poorer global sleep quality. In order to improve mental health, future researchers should pay more attention to individuals with childhood trauma, for its association with greater stress related to life events and poorer sleep quality.

The Intersection Between Childhood Trauma, the COVID-19 Pandemic, and Trauma-related and Psychotic Symptoms in People With Psychotic Disorders

INTRODUCTION

People with psychotic disorders may be disproportionately affected by the traumatic effects of the COVID-19 pandemic. Childhood trauma, which also increases vulnerability to subsequent stressors, is common in individuals with psychosis. In this study, we investigated the intersection of the pandemic, childhood trauma, and psychotic and trauma-related symptoms in individuals with psychotic disorders.

METHODS

We administered a cross-sectional survey to 151 participants [47 schizophrenia (SZ), 53 psychotic bipolar disorder (BP)], 51 healthy control (HC)] during the COVID-19 pandemic. Participants were asked about exposure to the pandemic's impacts, childhood trauma, and post-traumatic stress, dissociative, and psychotic symptoms.

RESULTS

BP reported greater negative impacts to emotional health than SZ and HC and to non-COVID physical health than HC. SZ reported less impact on work and employment during the pandemic. There were no other group differences in pandemic-related adversities. We also found that cumulative exposure to the pandemic's negative impacts was significantly associated with PTSD symptoms but not psychotic or dissociative symptoms. Moreover, the number of adversities an individual experienced during the pandemic was strongly associated with the cumulative number of traumatic experiences they had in childhood.

DISCUSSION

Our results suggest that having a psychotic disorder does not, in and of itself, increase susceptibility to the pandemic's negative impacts. Instead, we provide evidence of a graded relationship between cumulative exposure to the pandemic's negative impacts and PTSD symptom severity, as well as a graded relationship between cumulative childhood traumatic experiences and the number pandemic adversities, across diagnoses.
