J Affect Disord 2024; 361:209-216. [PMID: 38821368 DOI: 10.1016/j.jad.2024.05.164] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2024] [Revised: 04/23/2024] [Accepted: 05/28/2024] [Indexed: 06/02/2024]
Abstract
BACKGROUND Social support is a robust predictor of post-traumatic stress disorder (PTSD). Although the inverse relationship between perceived social support and PTSD (social causation model) is supported, less is understood about the antecedents of the social causation model. Further, there is limited research in non-Western psychiatric populations that experience elevated rates of trauma and PTSD (e.g., mood disorders). The present study evaluated whether cumulative traumatic life events influenced current PTSD symptoms through maladaptive personality traits and perceptions of social support among Asian patients with mood disorders. METHODS A total of 200 Asian patients (77.5 % Chinese) with mood disorders were assessed for maladaptive personality traits, perceptions of social support, cumulative traumatic life events, PTSD, and depressive symptoms. Structural equation modelling was conducted to evaluate the extended social causation model. RESULTS The extended social causation model demonstrated acceptable fit to the data (Comparative Fit Index [CFI] = 0.90; absolute Root Mean Square Error of Approximation [RMSEA] = 0.08). There were significant indirect effects of cumulative traumatic life events on current PTSD symptoms (β = 0.29, p < .001; 85 % variance explained) and depressive symptoms (β = 0.28, p < .001; 69 % variance explained). LIMITATIONS Results may not be generalizable beyond the Singapore population due to the socio-cultural and environmental context. CONCLUSIONS The present findings provide conceptual support for a maladaptive personality-informed model of social support and PTSD, which could better inform trauma-focused interventions in preventing and treating the debilitating effects of PTSD in psychiatric populations.

TRAUMA, VIOLENCE & ABUSE 2024; 25:1695-1708.

Abstract
Adverse childhood experiences (ACEs) studies reveal the profound impacts of experiencing trauma and hardships in childhood. However, the cumulative risk approach of treating ACEs obscures the heterogeneity of ACEs and their consequences, making actionable interventions impossible. latent class analysis (LCA) has increasingly been used to address these concerns by identifying underlying subgroups of people who experience distinctive patterns of co-occurring ACEs. Though LCA has its strengths, the existing research produces few comparable findings because LCA results are dependent on ACEs measures and indicators, which vary widely by study. Therefore, a scoping review of ACEs studies using LCA that focuses on ACEs measures, indicators, and findings is needed to inform the field. Following Arksey and O'Malley's five-stage scoping review methodological framework, we first identified 211 articles from databases of EBSCOhost, PubMed, and Scopus using "adverse childhood experiences" for title search and "latent class analysis" for abstract search. Based on the inclusion criteria of peer-reviewed articles written in English published from 2012 to 2022 and the exclusion criteria of nonempirical studies and the LCA not analyzing ACEs, we finally selected 58 articles in this scoping review. Results showed LCA has been increasingly endorsed in the ACEs research community to examine the associations between ACEs and human health and well-being across culturally diverse populations. LCA overcame the limitations of the traditional methods by revealing specific ACEs clusters that exert potent effects on certain outcomes. However, the arbitrary nature of selecting ACEs indicators, measures, and the limited use of theory impedes the field from moving forward.

CHILD ABUSE & NEGLECT 2024:106711. [PMID: 38388324 DOI: 10.1016/j.chiabu.2024.106711] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Revised: 01/10/2024] [Accepted: 02/15/2024] [Indexed: 02/24/2024]
Abstract
BACKGROUND Adverse Childhood Experiences (ACEs) can be passed onto future generations through complex biopsychosocial mechanisms. However, social support in caregivers who have experienced adversity may lead to adaptation. Most research on the intergenerational consequences of ACEs has focused on mental health in subsequent generations, while overlooking family functioning as an outcome. OBJECTIVE This pre-registered study addresses this gap by examining a hypothesized association between caregiver ACEs and caregiver-perceived family functioning, and the moderating role of social support. It was expected that high levels of social support would attenuate the association between caregiver ACEs and family functioning, controlling for contemporaneous stressors in the context of the COVID-19 pandemic. PARTICIPANTS AND SETTING Data come from a multinational non-clinical sample (n = 310). METHODS Caregivers completed self-report measures to assess caregiver ACEs, social support, COVID stressors, and family dysfunction. RESULTS Multiple regression analyses revealed that the ACEs-by-social support interaction was not significant. Exploratory analyses revealed a significant three-way interaction between COVID stressors, ACEs, and social support (b = 0.001, SE < 0.001, p = .008). For lower adversity, social support protected against the association between COVID stressors and family dysfunction; however, for higher adversity, social support was only protective when COVID stressors were low. CONCLUSIONS Social support is protective against concurrent stressors during the pandemic in relation to family functioning, though this buffering depends on historical levels of adversity. Findings are interpreted through a trauma-informed lens and provide support for family-focused interventions and policies to mitigate the impact of stress on caregivers with high ACEs.

Co-occurrence patterns of adverse childhood experiences and their associations with non-suicidal self-injury and suicidal behaviors and gender difference among middle school students: A three-city survey in China. J Affect Disord 2023; 320:140-147. [PMID: 36181912 DOI: 10.1016/j.jad.2022.09.124] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Revised: 09/15/2022] [Accepted: 09/26/2022] [Indexed: 02/02/2023]
Abstract
BACKGROUND Previous research has found increasing evidence of adverse childhood experiences (ACEs) leading to non-suicidal self-injury (NSSI) and suicidal behaviors. Most studies have focused on a certain type or timing of ACEs or the patterns of multiple types; however, few of them have examined the patterns of ACEs combined types and timing and the gender differences in the association between ACEs and self-harming behaviors. METHODS A cross-sectional survey was conducted in three Chinese cities from November 2020 to May 2021. We asked 16,853 middle school students to anonymously complete a questionnaire to provide the details of their own ACEs and NSSI or suicidal behaviors. RESULTS Latent class analysis identified four classes: high ACEs (10 %), high abuse/neglect (20.3 %), moderate ACEs (26.7 %) and low ACEs (43 %). Logistic regression models demonstrated that students in the high ACEs, high abuse/neglect and moderate ACEs subgroups were more likely to engage in NSSI and suicidal behaviors than students with low ACEs. Compared with boys, girls had a higher probability of engaging in NSSI and suicidal behaviors when exposed to the same level of ACEs. CONCLUSION Co-occurrence of ACEs is associated with high risk of NSSI and suicidal behaviors. Our findings recognized the most dangerous patterns and latent class membership, which supply the evidence for policy makers to adopt preventive measures to protect high-risk individuals. Strategies to relieve the impact of ACEs, especially on girls, need to be considered comprehensively. LIMITATIONS The study was limited by cross-sectional design, as causality could not be confirmed. In addition, because our survey was retrospective, potential recall bias can not be ignored.

Johnson D, Browne DT, Meade RD, Prime H, Wade M. Latent Classes of Adverse and Benevolent Childhood Experiences in a Multinational Sample of Parents and Their Relation to Parent, Child, and Family Functioning during the COVID-19 Pandemic. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:13581. [PMID: 36294161 PMCID: PMC9603677 DOI: 10.3390/ijerph192013581] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/02/2022] [Revised: 10/06/2022] [Accepted: 10/14/2022] [Indexed: 06/16/2023]
Abstract
Adverse Childhood Experiences (ACEs) are known to contribute to later mental health. Conversely, Benevolent Childhood Experiences (BCEs) may buffer against mental health difficulties. The importance of ACEs and BCEs for mental health of both parents and children may be most obvious during periods of stress, with potential consequences for functioning of the family. Subgroups of ACEs and BCEs in parents during the COVID-19 pandemic were investigated and validated in relation to indices of parent, child, and family well-being. In May 2020, ACEs/BCEs were assessed in 547 parents of 5-18-year-old children from the U.K., U.S., Canada, and Australia. Subgroups of parents with varying levels of ACEs and BCEs were identified via latent class analysis. The subgroups were validated by examining associations between class membership and indices of parent and child mental health and family well-being. Four latent classes were identified: low-ACEs/high-BCEs, moderate-ACEs/high-BCEs, moderate-ACEs/low-BCEs, and high-ACEs/moderate-BCEs. Regardless of the extent of BCEs, there was an increased risk of parent and child mental health difficulties and family dysfunction among those reporting moderate-to-high levels of ACEs. Parents' history of adversity may influence the mental health of their family. These findings highlight the importance of public health interventions for preventing early-life adversity.

CHILD ABUSE & NEGLECT 2022; 131:105778. [PMID: 35820323 DOI: 10.1016/j.chiabu.2022.105778] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Revised: 06/21/2022] [Accepted: 06/30/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Epidemiological studies show that adverse childhood experiences (ACE) are associated with positive psychotic symptoms in Western populations; however, there is a lack of population-based data in multi-ethnic, Asian societies. OBJECTIVE We investigated the associations between ACE (type and dosage) and positive psychotic symptoms in a nationally representative study in Singapore. PARTICIPANTS AND SETTING A total of 4441 adult Singapore residents were recruited via door-to-door surveys; they were assessed for ACE and positive psychotic symptoms (i.e., hallucinations, delusions, thought insertion, thought control, and telepathic powers) on structured interviews. METHODS Lifetime experiences of positive psychotic symptoms were regressed on (1) the experience of any ACE; (2) cumulative ACE; and (3) the experience of either no ACE, interpersonal victimization only, dysfunctional home environments only, neglect only or multiple exposures to ACE in weighted and adjusted regression models. RESULTS 5.2 % of the sample experienced positive psychotic symptoms during their lifetime. Individuals exposed to dysfunctional home environments (OR = 2.84, 95 % CI 1.26 to 6.37) and multiple adverse childhood experiences (OR = 3.31, 95 % CI 2.18 to 5.01) were at an elevated risk of experiencing positive psychotic symptoms. The exposure to three or more ACE was associated with a near five-fold higher risk of experiencing positive psychotic symptoms (OR = 4.51, 95 % CI 2.89 to 7.05). CONCLUSIONS Individuals exposed to dysfunctional home environments or multiple adverse childhood experiences are at an elevated risk of experiencing positive psychotic symptoms. Given the intrafamilial nature of these childhood adversities, dual-generation approaches and family-centered interventions are key.
