Intergenerational transmission of parent adverse childhood experiences to child outcomes: A systematic review and meta-analysis.

OBJECTIVE: The current meta-analytic review provides a comprehensive synthesis of studies examining parent exposure to ACEs and the developmental and mental health outcomes of their children. PARTICIPANTS AND SETTING: Eligible studies up to August 2021 were identified through comprehensive database searches in PsycINFO, MEDLINE, and Embase. Studies that were included examined the intergenerational effects of parent ACEs on child development (i.e., cognitive, language, motor, social difficulties, and early social-emotional development) or mental health (i.e., internalizing problems, externalizing problems) outcomes. METHODS: Data were extracted by two coders using a standardized extraction protocol. A multi-level meta-analytic approach was used to derive pooled effect sizes and test for moderators. RESULTS: A total of 52 studies were included in the meta-analysis. Parent ACEs were positively associated with child mental health problems (r=0.17, 95% CI [0.12, 0.21], p<.001), child externalizing difficulties (r=0.20, 95% CI [0.15, 0.26], p<.001), and child internalizing difficulties (r=0.17, 95% CI [0.11, 0.22], p<.001). There were no significant sociodemographic (i.e., child age, parent age, income level, child sex, or racial/ethnic minority status) or methodological (i.e., study type or quality) moderators of these associations. Preliminary evidence suggests that parent ACEs were not associated with offspring developmental outcomes, such as cognitive or language skills. CONCLUSIONS: Results suggest that parent ACEs are associated with some, but not all child outcomes. Additional research focused on the mechanisms of transmission are needed to inform policies and practices related to the intergenerational transmission of ACEs.

Associations between adverse childhood experiences and substance use: A meta-analysis.

BACKGROUND: Adverse childhood experiences (ACEs) can be associated with negative health outcomes such as substance use. However, extant literature assessing this association is mixed. OBJECTIVE: The present meta-analysis was conducted to obtain a pooled effect size for the association between ACEs and substance use (i.e., smoking, problematic alcohol use, heavy alcohol use, illicit drug use, and cannabis use). PARTICIPANTS AND SETTING: The present meta-analyses included 102 studies (N = 901,864), where 42.32 % of participants were male, and the mean age was 30.91 years. METHODS: Searches were conducted in MEDLINE, Embase, and PsycINFO in August 2021 and moderators were examined. Inclusion criteria included studies that measured ACEs prior to age 18 and substance use, and were published in English. All analyses were completed in Comprehensive Meta-Analysis Software, Version 3.0 (Borenstein et al., 2009). RESULTS: Pooled effect sizes between ACEs and smoking [OR = 1.803 (95 % CI 1.588, 2.048)], problematic alcohol use [OR = 1.812 (95 % CI 1.606, 2.044)], heavy alcohol use [OR = 1.537 (95 % CI 1.344, 1.758)], cannabis use [OR = 1.453 (95 % CI 1.184, 1.786)] and illicit drug use [OR = 1.695 (95 % CI 1.530, 1.878)] were significant. Significant moderators contribute to the understanding of the association between ACEs and substance use, and are discussed extensively. CONCLUSIONS: ACEs confer risk for substance use and trauma-informed approaches to substance use treatment should be considered. Study limitations and implications are discussed.

Adverse childhood experiences: a meta-analysis of prevalence and moderators among half a million adults in 206 studies.

Exposure to adverse childhood experiences (ACEs), including maltreatment and family dysfunction, is a major contributor to the global burden of disease and disability. With a large body of international literature on ACEs having emerged over the past 25 years, it is timely to now synthetize the available evidence to estimate the global prevalence of ACEs and, through a series of moderator analyses, determine which populations are at higher risk. We searched studies published between January 1, 1998 and August 5, 2021 in Medline, PsycINFO and Embase. Study inclusion criteria were using the 8- or 10-item ACE Questionnaire (±2 items), reporting the prevalence of ACEs in population samples of adults, and being published in English. The review protocol was registered with PROSPERO (CRD42022348429). In total, 206 studies (208 sample estimates) from 22 countries, with 546,458 adult participants, were included. The pooled prevalence of the five levels of ACEs was: 39.9% (95% CI: 29.8-49.2) for no ACE; 22.4% (95% CI: 14.1-30.6) for one ACE; 13.0% (95% CI: 6.5-19.8) for two ACEs; 8.7% (95% CI: 3.4-14.5) for three ACEs, and 16.1% (95% CI: 8.9-23.5) for four or more ACEs. In subsequent moderation analyses, there was strong evidence that the prevalence of 4+ ACEs was higher in populations with a history of a mental health condition (47.5%; 95% CI: 34.4-60.7) and with substance abuse or addiction (55.2%; 95% CI: 45.5-64.8), as well as in individuals from low-income households (40.5%; 95% CI: 32.9-48.4) and unhoused individuals (59.7%; 95% CI: 56.8-62.4). There was also good evidence that the prevalence of 4+ ACEs was larger in minoritized racial/ethnic groups, particularly when comparing study estimates in populations identifying as Indigenous/Native American (40.8%; 95% CI: 23.1-59.8) to those identifying as White (12.1%; 95% CI: 10.2-14.2) and Asian (5.6%; 95% CI: 2.4-10.2). Thus, ACEs are common in the general population, but there are disparities in their prevalence. They are among the principal antecedent threats to individual well-being and, as such, constitute a pressing social issue globally. Both prevention strategies and downstream interventions are needed to reduce the prevalence and mitigate the severity of the effects of ACEs and thereby reduce their deleterious health consequences on future generations.

Adverse childhood experiences and intimate partner violence: A meta-analysis.

Intimate partner violence (IPV) represents a significant public health concern. Adverse childhood experiences (ACEs) represent one risk factor for IPV, however, the results of existing research on the association between ACEs and IPV demonstrate mixed findings. The present research sought to meta-analytically examine the association between ACEs and (a) IPV perpetration and (b) IPV victimization. Moderator analyses were conducted to determine factors that may impact the association between ACEs and IPV involvement. Electronic searches were conducted in MEDLINE, Embase, and PsycINFO in August of 2021. One-hundred and twenty-three records were screened for inclusion. All studies included a measure of ACEs and IPV victimization or perpetration. Among the 27 studies and 41 samples included in the meta-analysis, 65,330 participants were included. The results of the meta-analyses demonstrated that ACEs were positively associated with IPV perpetration and victimization. Significant methodological and measurement moderators further inform our understanding of ACEs and IPV involvement. The present meta-analyses demonstrates that trauma-informed approaches to IPV screening, prevention, and intervention may be useful, given that individuals who are involved with IPV may be more likely to possess a history of ACEs exposure.

When the Bough Breaks: A systematic review and meta-analysis of mental health symptoms in mothers of young children during the COVID-19 pandemic.

Parents have experienced considerable challenges and stress during the COVID-19 pandemic, which may impact their well-being. This meta-analysis sought to identify: (1) the prevalence of depression and anxiety in parents of young children (

Los padres han experimentado retos considerables y estrés durante la pandemia del COVID-19, lo cual puede tener un impacto en su bienestar. Este metaanálisis busca identificar: 1) la prevalencia de la depresión y ansiedad en los padres de niños pequeños (

Les parents ont fait l'expérience de défis considérables et d'un stress considérable durant la pandémie du COVID-19, ce qui peut impacter leur bien-être. Cette méta-analyse s'est donné pour but d'identifier: 1) la prévalence de la dépression et de l'anxiété chez les parents de jeunes enfants (<âge 5) durant la pandémie du COVID-18, et 2) les facteurs de modération sociodémographique (par exemple, l'âge du parent, le fait d'être d'une minorité raciale) et méthodologique (par exemple, la qualité de l'étude) qui expliquent l'hétérogénéité dans les étudies. Une recherche systématique a été faite au travers de quatre banques de données du premier janvier 2020 au 3 mars 2021. Un total de 18 études ne se recoupant pas (8981 participants), toutes focalisées sur la santé mentale maternelle, ont rempli les critères d'inclusion. Des méta-analyses à effet aléatoire approprié ont été faites. Les estimations de prévalences regroupées pour une dépression cliniquement importante et des symptômes d'anxiété pour les mères de jeunes enfants durant la pandémie de COVID-19 étaient respectivement de 26,9% (95% CI: 21,3-33,4) et de 41,9% (95% CI: 26,7-58,8). La prévalence d'une dépression cliniquement élevée et de symptômes d'anxiété était plus élevée en Europe et en Amérique du Nord et chez les mères plus âgées. Les symptômes dépressifs cliniquement élevés étaient plus bas dans les études avec un pourcentage plus élevé d'individus de minorités raciales. Par comparaison les symptômes d'anxiété cliniquement élevés étaient plus haut dans les études de moindre qualité d'étude et dans les échantillons avec des mères très éduquées. Les politiques et les ressources visant des améliorations dans la santé mentale maternelle sont essentielles.

Post-secondary Student Mental Health During COVID-19: A Meta-Analysis.

The COVID-19 pandemic has posed notable challenges to post-secondary students, causing concern for their psychological well-being. In the face of school closures, academic disruptions, and constraints on social gatherings, it is crucial to understand the extent to which mental health among post-secondary students has been impacted in order to inform support implementation for this population. The present meta-analysis examines the global prevalence of clinically significant depression and anxiety among post-secondary students during the COVID-19 pandemic. Several moderator analyses were also performed to examine sources of variability in depression and anxiety prevalence rates. A systematic search was conducted across six databases on May 3, 2021, yielding a total of 176 studies (1,732,456 participants) which met inclusion criteria. Random-effects meta-analyses of 126 studies assessing depression symptoms and 144 studies assessing anxiety symptoms were conducted. The pooled prevalence estimates of clinically elevated depressive and anxiety symptoms for post-secondary students during the COVID-19 pandemic was 30.6% (95% CI: 0.274, 0.340) and 28.2% (CI: 0.246, 0.321), respectively. The month of data collection and geographical region were determined to be significant moderators. However, student age, sex, type (i.e., healthcare student vs. non-healthcare student), and level of training (i.e., undergraduate, university or college generally; graduate, medical, post-doctorate, fellow, trainee), were not sources of variability in pooled rates of depression and anxiety symptoms during the pandemic. The current study indicates a call for continued access to mental health services to ensure post-secondary students receive adequate support during and after the COVID-19 pandemic.

Global Prevalence of Depressive and Anxiety Symptoms in Children and Adolescents During COVID-19: A Meta-analysis.

Importance: Emerging research suggests that the global prevalence of child and adolescent mental illness has increased considerably during COVID-19. However, substantial variability in prevalence rates have been reported across the literature. Objective: To ascertain more precise estimates of the global prevalence of child and adolescent clinically elevated depression and anxiety symptoms during COVID-19; to compare these rates with prepandemic estimates; and to examine whether demographic (eg, age, sex), geographical (ie, global region), or methodological (eg, pandemic data collection time point, informant of mental illness, study quality) factors explained variation in prevalence rates across studies. Data Sources: Four databases were searched (PsycInfo, Embase, MEDLINE, and Cochrane Central Register of Controlled Trials) from January 1, 2020, to February 16, 2021, and unpublished studies were searched in PsycArXiv on March 8, 2021, for studies reporting on child/adolescent depression and anxiety symptoms. The search strategy combined search terms from 3 themes: (1) mental illness (including depression and anxiety), (2) COVID-19, and (3) children and adolescents (age ≤18 years). For PsycArXiv, the key terms COVID-19, mental health, and child/adolescent were used. Study Selection: Studies were included if they were published in English, had quantitative data, and reported prevalence of clinically elevated depression or anxiety in youth (age ≤18 years). Data Extraction and Synthesis: A total of 3094 nonduplicate titles/abstracts were retrieved, and 136 full-text articles were reviewed. Data were analyzed from March 8 to 22, 2021. Main Outcomes and Measures: Prevalence rates of clinically elevated depression and anxiety symptoms in youth. Results: Random-effect meta-analyses were conducted. Twenty-nine studies including 80 879 participants met full inclusion criteria. Pooled prevalence estimates of clinically elevated depression and anxiety symptoms were 25.2% (95% CI, 21.2%-29.7%) and 20.5% (95% CI, 17.2%-24.4%), respectively. Moderator analyses revealed that the prevalence of clinically elevated depression and anxiety symptoms were higher in studies collected later in the pandemic and in girls. Depression symptoms were higher in older children. Conclusions and Relevance: Pooled estimates obtained in the first year of the COVID-19 pandemic suggest that 1 in 4 youth globally are experiencing clinically elevated depression symptoms, while 1 in 5 youth are experiencing clinically elevated anxiety symptoms. These pooled estimates, which increased over time, are double of prepandemic estimates. An influx of mental health care utilization is expected, and allocation of resources to address child and adolescent mental health concerns are essential.

Adverse childhood experiences and maternal anxiety and depression: a meta-analysis.

BACKGROUND: It has been proposed that adverse childhood experiences (ACEs) can put women at risk for mental illness in the pregnancy and postpartum periods. While some studies have found strong support for this proposition, others have found weak or no support. This study is a meta-analysis of the association between ACEs and maternal mental health to resolve between-study discrepancies, and to examine potential moderators of associations. METHODS: Three electronic databases (i.e., MEDLINE, Embase, and PsycINFO) were searched up to November 2018 by a health sciences librarian. A hand search was conducted in January 2020 and relevant studies were added. Included studies reported on associations between ACEs and maternal depression and/or anxiety in the perinatal period (pregnancy to 1-year postpartum). Pregnancy and postpartum outcomes were examined separately for both depression and anxiety. Random-effect meta-analyses were conducted. Moderator analyses were conducted using meta-regression. Study quality was evaluated using a 15-point scale. RESULTS: The initial search yielded 4646 non-duplicate records and full text review occurred for 196 articles. A total of 15 studies (N = 7788) were included in the meta-analyses, of which 2 were also described narratively. Publication year ranged from 1998 to 2019. Mothers were approximately 28.93 years of age when they retrospectively reported on their ACEs. All studies had maternal self-report questionnaires for the mental health outcomes. Study quality ranged from 7 to 12. The pooled effect sizes between ACEs and prenatal (N = 12; r = .19; 95% CI= .13, .24) and postpartum (N = 7; r = .23; 95% CI = .06 to .39) depressive symptoms were significant. The pooled effect size between ACEs and prenatal anxiety was also significant (N = 5; r = .14; 95% CI= .07, .21). Moderator analyses indicated that timing of depressive and anxiety symptoms may be important for understanding associations. CONCLUSIONS: ACEs confer risk to maternal mental health, albeit effect sizes are small to moderate in magnitude. Trauma-informed approaches, as well as increased mental health support during and after pregnancy, may help to offset the relative risk of ACEs on maternal mental health.

Differences in Demographic, Risk, and Protective Factors in a Clinical Sample of Children who Experienced Sexual Abuse Only vs. Poly-victimization.

Children exposed to child sexual abuse (CSA) vary considerably with regards to their presenting concerns and treatment needs. One factor creating heterogeneity amongst children experiencing CSA is their history of experiencing other victimizations (i.e., poly-victimized or not). However, little is known about risk factors for poly-victimization as well as differences in protective factors among these two groups. Additionally, there is currently limited understanding of whether poly-victimization is associated with greater trauma symptoms in children exposed to CSA and being seen for trauma treatment. Using a clinical sample of 117 children who were sexually abused (64 CSA only and 53 poly-victimized) ranging from age 3-18 years, the current study examined demographic characteristics, abuse characteristics, trauma symptoms, and protective factors using casefile review methodology. After accounting for other risk factors, parental abuse history and protective factors were significantly associated with child poly-victimization status. Children exposed to poly-victimization were more likely to have financial concerns χ ( 1 , 115 ) 2 = 4.16, p = 0.04, parents with abuse histories χ ( 1 , 117 ) 2 = 8.93, p = 0.003, and parents with histories of mental health or substance use difficulties χ ( 1 , 117 ) 2 = 4.02, p = 0.045. Although cumulative trauma symptoms scores were higher for children who were poly-victimized compared to CSA only, t (115) = -2.24, p = 0.03, multiple regression analyses showed that poly-victimization status was not significantly associated with child trauma symptoms after accounting for other demographic and abuse characteristics. Assessing and understanding the extent to which children exposed to CSA have experienced other forms of maltreatment is critical for identifying children who may be most at risk of poor outcomes.

Meditating in virtual reality: Proof-of-concept intervention for posttraumatic stress.

Objective: We investigate the potential therapeutic application of virtual reality (VR) technology as an aid to meditation practice among persons varying in posttraumatic stress disorder (PTSD) symptoms. Method: In this within-group mixed-methods study, 96 young adults practiced both VR- and non-VR-guided meditations and reported on their experience of positive affect (PA), negative affect (NA), other meditative experiences and perceived satisfaction-credibility of each meditation. Results: Participants reported more PA and greater perceived satisfaction-credibility following the VR as compared to non-VR-guided meditations primarily when the VR meditation was practiced first, before the non-VR meditation, as opposed to vice versa. The experience of NA during meditation practice was infrequent, although persons with increased PTSD symptoms reported increased distress during both VR and non-VR meditation. Conclusions: Further study of therapeutic applications of VR as an aid to meditation practice among people with PTSD symptoms is warranted.

Proof of Concept of an Eclectic, Integrative Therapeutic Approach to Mental Health and Well-Being Through Virtual Reality Technology.

Across three studies, we provide a proof-of-concept evaluation of an integrative psychotherapeutic application of virtual reality (VR) technology. Study 1 (n = 36) evaluated an unguided "safe-place" imagery task, where participants were instructed "to create a safe space… [such as] a scene, item, design, or any visual representation that makes you feel safe" using either the Google Tilt Brush application (VR condition), the standard Microsoft Paint application (2-D condition), or via eyes-closed mental imagery alone (IMG condition). Study 2 (n = 48) evaluated a narrative episodic recall task, where participants viewed their childhood and adult homes and places of schooling either using either the Google Earth VR application (VR condition) or the standard Google Earth application (2-D condition) or recalled these places with their eyes closed via mental imagery alone (IMG condition). Finally, Study 3 (n = 48) evaluated a guided wilderness imagery task, during which different scripts were narrated, specifically, a trail walk in autumn, a spring meadow, and a hillside walk in snowy winter, while either these same scenes were visually presented using the Nature Treks VR application (VR condition), the scenes were presented using the same software but shown on standard computer monitor (2-D condition), or participants' eyes were closed (IMG condition). Order of intervention format was randomized across participants. Across all three studies, quantitative survey ratings showed that the VR format of intervention delivery produced greater positive affect and satisfaction and perceived credibility ratings as an intervention for trauma- and stressor-related disorders and psychological well-being as rated by university students who varied in traumatic and stressful life event history and symptoms of posttraumatic stress disorder, whereas qualitative findings revealed additional themes of experiential response including increased experience of presence and vividness in the VR condition. Future research directions and clinical applications are discussed.

Lifetime traumatic stressors and adverse childhood experiences uniquely predict concurrent PTSD, complex PTSD, and dissociative subtype of PTSD symptoms whereas recent adult non-traumatic stressors do not: results from an online survey study.

This retrospective survey study compared the differential risk of lifetime traumatic stressors, so-called "non-traumatic stressors" experienced over the past year, referring to life events that do not meet the criteria for A1 traumatic events, and adverse childhood experiences (ACE) on severity of DSM-5 versus ICD-11 PTSD, Complex PTSD (CPTSD), and dissociative subtype of PTSD (D-PTSD) symptoms among 418 participants recruited online. In pairwise analyses, all stress types were associated with all outcomes. However, multiple regression and factor analyses indicated that whereas the number of different lifetime traumatic events participants reported experiencing, together with the number of ACE participants experienced, uniquely predicted DSM-5 PTSD, D-PTSD and ICD-11 PTSD and CPTSD symptoms, the number of non-traumatic stressors they experienced during the last year did not. Moreover, ACE uniquely predicted all outcomes even after accounting for lifetime traumatic stress. These results provide further support for the particularly high risk of lifetime traumatic stressors and ACE in predicting trauma and stressor-related symptoms. Future research directions are discussed.

Este estudio de encuesta retrospectiva comparó el riesgo diferencial de los factores estresantes traumáticos durante la vida, los llamados "factores estresantes no traumáticos" experimentados durante el último año, refiriéndose a los eventos de la vida que no cumplen con los criterios para eventos traumáticos A1 y las experiencias adversas en la infancia (ACE) sobre la gravedad del TEPT en el DSM-5 frente al ICD-11, el TEPT complejo (TEPT-C) y síntomas del subtipo disociativo del TEPT (TEPT-D) entre 418 participantes reclutados online. En los análisis por pares, todos los tipos de estrés se asociaron con todos los resultados. Sin embargo, la regresión múltiple y los análisis factoriales indicaron que, mientras que la cantidad de eventos traumáticos diferentes durante la vida que los participantes reportaron haber experimentado, junto con la cantidad de ACE que los participantes experimentaron, predicen inequívocamente los síntomas concurrentes, no fue así con la cantidad de factores estresantes no traumáticos que experimentaron durante el último año. Además, ACE predijo de forma única todos los resultados incluso después de tener en cuenta el estrés traumático durante la vida. Estos resultados brindan apoyo adicional para predecir el riesgo de síntomas relacionados al trauma y estrés, siendo particularmente alto en estresores traumáticos durante la vida y ACE. Se discuten futuras direcciones de investigación.
