Talmon A, Shilo G, Tsur N. Intergenerational associations between childhood maltreatment, post-traumatic stress symptoms, and chronic pain in young adult offspring and their parents. Stress Health 2024; 40:e3441. [PMID: 38949630 DOI: 10.1002/smi.3441] [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: 10/25/2023] [Revised: 05/29/2024] [Accepted: 06/23/2024] [Indexed: 07/02/2024]
Abstract
Findings have revealed a strong link between exposure to child maltreatment (CM) and later chronic pain. Concurrently, other findings have been grounded in the understanding that CM consequences may not end with the exposed individual, rather, they extend to their offspring. However, little is known regarding the possible intergenerational transmission of chronic pain following CM. This study examines whether chronic pain among parents and their young adult offspring may be associated with parental exposure to CM. Three hundred ninety-three parent-offspring dyads (parents' mean age = 58, SD = 5.91 years; offspring's mean age = 27, SD = 3.91 years) completed self-report questionnaires, assessing CM (CTQ), posttraumatic stress (PTS) and disturbances in self-organisation (DSO) symptoms (ITQ), and chronic pain. CM was associated with chronic pain mediated by DSO symptoms among parents (indirect effect = 0.77; p = 0.007) and PTS symptoms among offspring (indirect effect = 0.285; p = 0.005). Offspring chronic pain was significantly associated with parental CM through two intergenerational paths: the mediation of parents' DSO symptoms and chronic pain (indirect effect = 0.298; p = 0.011), and through parents' PTS symptoms and offspring's PTS symptoms (indirect effect = 0.077; p = 0.004). This study's findings support the relevance of the intergenerational transmission of chronic pain following parental exposure to CM. Furthermore, the findings reveal complex PTS symptoms as a possible underlying mechanism for the intergenerational associations of chronic pain following CM.

Exploring networks of complex developmental trauma symptomatology among children and adolescents involved in child welfare. JCPP ADVANCES 2024; 4:e12224.

Abstract
Background Clinical presentations of child and adolescent psychopathology can vary systematically for boys and girls. While network analysis is increasingly being applied to explore psychopathology in adults, there is a dearth of network studies considering differences in symptoms for boys and girls, particularly in developmental trauma-related symptomatology. Methods This study involves rural children (n = 375, 39.47% girls) and adolescents (n = 291, 51.20% girls) involved with child protection services in Ontario, Canada. Caregivers completed the Assessment Checklist for Children or Adolescents within the first 6 months of care. Psychometric network analyses were conducted using subscales for boys and girls. Differences were examined via network comparison permutation tests, moderated network models, and independent t-tests. Results Attachment-related interpersonal difficulties were the most central nodes in the child and adolescent networks for both boys and girls. Emotional dysregulation also had high strength centrality for adolescents. While network comparison tests found the overall network structures and global network strength to be invariant between boys and girls for children and adolescents, moderated network models and independent t-tests revealed several differences with regards to the expression of specific symptoms. Among children, girls exhibited more indiscriminate and pseudomature interpersonal behaviors, whereas boys expressed significantly more non-reciprocal interpersonal behaviors and self-injury. Adolescent girls exhibited more behavioral dysregulation and suicide discourse in the moderated network model; t-tests also indicated higher levels of emotional dysregulation, negative self-image, and other items considered clinically important complex trauma symptoms (e.g., distrust of adults, confused belonging). Discussion This study supports evidence of differences in the expression of complex trauma symptomatology for boys and girls. Additionally, girls exhibit more symptoms, in general. Consistent with the transdiagnostic conceptualization of the consequences of developmental trauma, findings demonstrate the primacy of attachment-specific difficulties and emotion dysregulation.

The effect of complex posttraumatic stress and poverty on quality of life among adult survivors of childhood institutional maltreatment: evidence from survivors of the 'Hyeongje Welfare Institution' in South Korea. Eur J Psychotraumatol 2024; 15:2328505. [PMID: 38502029 PMCID: PMC10953780 DOI: 10.1080/20008066.2024.2328505] [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: 09/16/2023] [Accepted: 02/29/2024] [Indexed: 03/20/2024] Open
Abstract
Background: Childhood institutional maltreatment (IM) is associated with both complex posttraumatic stress disorder (CTPSD) and poverty in adulthood life, each of which may impact an individual's quality of life (QoL). To find implications for clinical practice and policy making for adult survivors with childhood IM experiences, it is necessary to conduct research examining their current QoL and identifying related factors.Objective: By applying the model of the conservation of resources theory, we focused on how adulthood QoL can be indicated by childhood IM as well as the life outcomes of IM such as additional lifetime trauma, CPTSD, and poverty.Methods: In a cross-sectional study, self-report data were collected from 127 adults who were survivors of the 'Hyeongje' childhood IM in South Korea. We conducted regression analyses of childhood IM experiences, trauma experiences after escape from the institution, current CPTSD symptoms, and current poverty experiences on current QoL.Results: The duration of placement at the 'Hyeongje' (β = .24, p = .009) was associated with trauma experiences after escape from the institution. Trauma experiences after escape from the institution (β = .25, p = .007) were associated with CPTSD symptoms. CPTSD symptoms (β = .26, p = .005) were associated with poverty, and both CPTSD symptoms (β = -.52, p < .001) and poverty (β = -.26, p = .003) were negatively associated with current QoL.Conclusions: Prolonged childhood IM brings about loss spirals by increasing an individual's exposure to experiences of further cumulative trauma, CPTSD, and poverty. There is a need for due diligence-based policy making and public support from the government to help create upward spirals for QoL. This may include the imminent detection and rescue of children as well as providing a safe environment, offering multidisciplinary interventions including evidence-based treatment for CPTSD, and considering economic support including collective reparations.

CHILD ABUSE & NEGLECT 2023; 141:106191. [PMID: 37084615 DOI: 10.1016/j.chiabu.2023.106191] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Revised: 03/09/2023] [Accepted: 04/03/2023] [Indexed: 05/03/2023]
Abstract
BACKGROUND Adverse Childhood Experiences (ACE) are associated with many deleterious outcomes in young offenders. There is a dearth of studies examining its effects on young offenders' antisocial attitudes, disruptive behaviors and aggression, risk factors for delinquency and reoffending. OBJECTIVE This study examined ACE patterns and their association with the above factors in young offenders. PARTICIPANTS AND SETTING 1130 youth offenders (964 males; Mage = 17.57 years), provided self-reports on ACEs, antisocial attitudes, disruptive behavior ratings and aggression. METHOD Latent Class Analysis was performed on 12 self-reported ACEs, followed by Analyses of Covariance on each of the measures. RESULTS Four classes - Low ACE, Indirect Victims, Abusive Environment, and Polyvictimized - were identified. Polyvictimized youths had the highest levels of conduct problems (M = 70.35, ps < .05) and proactive aggression (M = 0.45, ps < .05) but did not differ from youths in Abusive Environment in reactive aggression (M = 1.02, p = .69), oppositional problems (M = 65.15, p = .18), and antisocial attitudes (M = 26.95, p = .21). Indirect Victims had lower levels of conduct problems (M = 64.80, p < .05) and antisocial attitudes (M = 24.35, p < .05) than Polyvictimized youths but higher levels of these outcomes than the Low ACE group. CONCLUSIONS Our findings showed that ACEs patterns vary in their effects on antisociality and disruptive behaviors. The novel finding was that childhood victimization does not have to be direct, as indirect victimization significantly impacted factors important to delinquency and reoffending.

Abstract
Emerging research evidence suggests that benevolent childhood experiences (BCEs) may partly explain more favourable mental health outcomes among individuals affected by adverse childhood experiences (ACEs). However, much of this research has focused on adult populations. Consequently, this study sought to provide the first rigorous assessment of the prevalence and predictors of BCEs using a nationally representative sample of young people from Northern Ireland (NI). Participants were 11-19-years-olds (N = 1293) who participated in the NI Youth Wellbeing Prevalence Survey (NI-YWS, 2020). Prevalence rates, gender differences and predictors of BCEs were investigated. Results revealed how most of the sample experienced multiple BCEs (95%, n = 1084), with females reporting higher levels of BCEs. Significant positive predictors of BCEs were female gender, parental education, living with both biological parents, and living in areas with lower deprivation, while significant negative predictors of BCEs included family being in receipt of social welfare and older age. Overall, this study highlights how BCEs are common, while the identification of factors associated with likelihood of having positive experiences during early development provides novel insights into those young people who may be at greater risk for maladaptive psychological outcomes.

Abstract
PURPOSE The Childhood Trauma Questionnaire-Short Form (CTQ-SF) is a widely used retrospective screening tool for childhood maltreatment in adults. Its properties are less known in adolescents. The objective was to investigate acceptability and psychometric properties when used in adolescents. METHOD A community sample of adolescents (n=1885) in four waves (from 13 or 14 to 17 years old) and a clinical sample (n=74, mean age 18), both from Sweden, were used to assess acceptability and different aspects of validity and reliability. RESULTS The CTQ-SF was found to be well-accepted. As expected, the community sample scored lower than the clinical sample on all maltreatment-scales and showed stability over-time. In the community sample, internal consistencies were substantial or excellent for all scales except Physical neglect, and in the clinical sample this was found for all scales. One-year test-retest consistencies of subscales were substantial or almost perfect, and for all scales, they increased from early to mid-adolescence. Directed inconsistencies on item level decreased from early to mid-adolescence. Convergent validity was shown in relation to scales on family climate, parental relations, and emotional health also from early adolescence. Discriminant analyses showed more moderate discriminatory ability although almost seven times better than by-chance. CONCLUSIONS The CTQ is well accepted and can be trusted to provide consistent and valid self-reports from the age of 14 on childhood maltreatment. Some caution is advised when used with younger adolescents, since the test-retest stability is then weaker, and the interpretation of the M/D scale is more ambiguous.

Validation of the International Trauma Questionnaire-Child and Adolescent Version (ITQ-CA) in a Chinese mental health service seeking adolescent sample. Child Adolesc Psychiatry Ment Health 2022; 16:66. [PMID: 35962396 PMCID: PMC9375312 DOI: 10.1186/s13034-022-00497-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2022] [Accepted: 07/13/2022] [Indexed: 12/27/2022] Open
Abstract
BACKGROUND The International Trauma Questionnaire-Child and Adolescent version (ITQ-CA) is a self-report measure that assesses posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) based on the diagnostic formulation of the 11th version of the International Classification of Diseases (ICD-11). This study aimed to provide a Chinese translation and psychometric evaluation of the ITQ-CA using a sample of mental-health service seeking adolescents in Mainland China. METHODS The ITQ-CA was translated and back-translated from English to simplified Chinese and finalized with consensus from an expert panel. Adolescents ages 12-17 were recruited via convenience sampling from an outpatient psychiatric clinic in Mainland China. Participants completed the ITQ-CA; measures of four criterion variables (depression, anxiety, stress, adverse childhood experiences); and the PTSD Checklist for DSM-5 (PCL-5). Construct validity, concurrent validity, and comparison of PTSD caseness between ICD-11 and DSM-5 measures were assessed. RESULTS The final sample consisted of 111 Chinese adolescents (78% female; mean age of 15.23), all diagnosed with a major depressive disorder. Confirmatory factor analysis indicated the two-factor second-order model provided optimal fit. All criterion variables were positively and significant correlated with the six ITQ-CA symptom cluster summed scores. In the present sample, 69 participants (62.16%) met symptom criteria for ICD-PTSD or CPTSD using the ITQ-CA, and 73 participants (65.77%) met caseness for DSM-5 PTSD using the PCL-5. Rates of PTSD symptom cluster endorsement and caseness deriving from both diagnostic systems were comparable. CONCLUSIONS The Chinese ITQ-CA has acceptable psychometric properties and confers additional benefits in identifying complex presentations of trauma-related responses in younger people seeking mental health services.

The latent structure of ICD-11 posttraumatic stress disorder (PTSD) and complex PTSD in a general population sample from USA: A factor mixture modelling approach. J Anxiety Disord 2022; 85:102497.

Abstract
The validity of ICD-11 Posttraumatic Stress Disorder (PTSD) and Complex PTSD (CPTSD), as measured by the International Trauma Questionnaire (ITQ; Cloitre et al., 2018) has been supported in many factor analytic and mixture modelling studies. There is, however, a paucity of research investigating the latent structure of the ITQ using factor mixture modelling (FMM). FMM was applied to data collected from a nationally representative sample of U.S. adults (N = 1834). FMM results demonstrated strong support for a two-factor second-order model with four qualitatively distinct latent classes: a 'PTSD class', a 'CPTSD class', a 'DSO' (Disturbances in Self-Organisation) class and a 'low symptoms class'. Sexual abuse increased likelihood of membership to the 'CPTSD' (OR = 3.22) and physical abuse decreased likelihood of membership to the 'PTSD' (OR=0.51). Trauma exposure in adulthood predicted 'PTSD' and 'CPTSD' class membership. The 'CPTSD class' was characterised by higher levels of psychopathological co-morbidities and poorer psychological wellbeing compared to all other classes. Results provide additional support for the validity of PTSD and CPTSD as measured by the ITQ.

Abstract
The 11th version of the International Classification of Diseases (ICD-11; WHO, 2018) describes two distinct trauma related disorders, Posttraumatic Stress Disorder (PTSD) and Complex PTSD (CPTSD). This review aims to summarise and synthesize evidence from factor analytic and mixture modelling studies that have investigated the latent structure of the International Trauma Questionnaire. A systematic search of PsycInfo, Web of Science, Scopus and Pubmed databases was conducted to identify relevant articles. Thirty-three studies met the inclusion criteria for this systematic review. The latent structure of the ITQ was best represented by two models; a correlated six-factor model (Re-experiencing, Avoidance, Threat, Affect Dysregulation, Negative Self Concept, and Disturbed Relationships) and a two-factor second-order model (PTSD and Disturbances in Self-Organization). Mixture model studies consistently identified distinct classes representing those displaying PTSD and CPTSD symptoms. Numerous studies demonstrated support for the factorial and discriminant validity of PTSD and CPTSD when analysed in conjunction with other variables. Overall, support was found for the conceptual coherence of PTSD and CPTSD as empirically distinguishable disorders, as measured by the ITQ. The available evidence demonstrates that the ITQ is a valid measure of ICD-11 PTSD and CPTSD. Recommendations for future research are included.
