A Latent Class Analysis of Childhood Maltreatment: Identifying Abuse Typologies

Patterns of life stress and the development of ruminative brooding in adolescence: A person-centered approach

Research links life stressors, including acute, chronic, and early life stress, to the development of ruminative brooding. However, singular forms of life stress rarely occur in isolation, as adolescents typically encounter stressors that vary on important dimensions (e.g., types, timings, quantities) across development. The current study employs latent profile analysis (LPA) to identify natural clusters of life stress that, over time, may be differently associated with ruminative brooding. Evaluations of episodic, chronic, and early life stress were conducted with community-recruited mid-adolescents (N = 241, Mage = 15.90 years, 53% female) and their parents using the UCLA Life Stress Interview and lifetime adversity portions of the Youth Life Stress Interview. Analyses identified four distinct patterns: low stress, high peer stress, moderate home / family stress, and multifaceted / high school stress. Adolescents in the high peer stress and moderate home / family stress profiles were at highest risk for developing a brooding style over time. Despite high overall levels of stress, teens in the multifaceted / high school stress profile were at not at elevated risk for developing a brooding style. Findings demonstrate the utility of person-centered approaches to identify patterns of stress exposure that heighten risk for brooding over time.

A nationally representative survey of ICD-11 PTSD among Danish adolescents and young adults aged 15-29

Posttraumatic stress disorder (PTSD) is recognized as a debilitating psychiatric disorder affecting populations worldwide. This has inspired many countries to estimate the national prevalence rates of PTSD in Europe and beyond. At present, there are no published representative studies that have assessed the occurrence of trauma exposure and PTSD in Denmark using a valid measurement based on ICD-11 criteria. A national sample of the general population of young Danish residents, ranging in age between 15 to 29 years (n = 2,434), was surveyed cross-sectionally from April to October 2022. Data weights were applied to ensure representativity of the sample. Multiple regression was used to study the relationship between trauma exposure, sex, age, and PTSD. Accidents and violence were the most common types of trauma exposure with females being more likely to experience sexual violence. A total of 7.7% endorsed probable PTSD with women reporting higher rates of clinical and subclinical PTSD (12.3% and 12.7%, respectively) than men (3.5% and 7.3%, respectively). Findings from the multiple regression showed that female gender was associated with higher PTSD-severity, although the strongest predictor was trauma-type with other types of traumas, and sexual violence displaying the strongest relationship to PTSD-severity overall. A dose-response relationship between the number of trauma types and PTSD symptomatology was found. This is the first study of PTSD in a nationally representative Danish sample using a valid measure of ICD-11 PTSD. The identified PTSD rates were higher than Danish official estimates in a representative sample of the Danish adolescent and young adult population (7.7% weighted compared to 1%). The study replicated international findings of sex differences in probable PTSD endorsement.

A qualitative study of coping strategies and resilience in the aftermath of childhood adversity in first-episode psychosis

AIM

Exposure to adversity during childhood is associated with elevated risk for commonly occurring forms of psychopathology, especially psychotic disorders. Despite the noteworthy consequences associated with adverse childhood experiences, an inconsistent and unpredictable number of at-risk populations present with remarkably good physical and mental health outcomes that can be attributed to resilience. This study aimed to qualitatively explore the experience of childhood adverse events and coping strategies employed by individuals that promote resilience and better mental health outcomes.

METHODS

Fourteen individuals with a history of childhood adversity were recruited to participate using a case-study approach. A semi-structured interview guide was developed based on empirical evidence and theoretical background, and the interviews were analysed using a reflexive thematic approach.

RESULTS

Our findings showed that the type of adversity impacted the experience of trauma, for example, the death of a caregiver versus emotional abuse or witnessing violence at home. Five coping strategies were identified (social support, religious coping, problem or emotion-focused coping, and meaning-making), with healthy controls found to identify and use these resources more than the psychosis group to promote individual well-being and better mental health outcomes.

CONCLUSIONS

Our findings provide insights into experiences in the aftermath of childhood adversity, emphasising the need to assess the history of trauma systematically. They further underscore the importance of mental health prevention programmes bolstering individual-level coping strategies and the resources available within our environments to help them manage adversity, improve overall outcomes, and promote resilience.

Does childhood maltreatment influence Chinese preschool education college students' depression and anxiety? Evidence from a latent class analysis

Introduction

Preschool teachers' mental health may be a critical factor in their job performance, which in turn can influence the quality of early childhood education. However, little is known about its development. Childhood maltreatment, as a chronic form of childhood stress, may influence later mental health development. Although large, comprehensive research has been undertaken on childhood maltreatment and mental health, the associations between these two variables need further exploration. This study aims to describe childhood maltreatment based on person-centered approaches in Chinese preschool education college students, and to examine the differences in depression and anxiety within subgroups of childhood maltreatment.

Methods

A total of 1,218 Chinese preschool education college students participated in this study, and the data analysis was based on unconditional and conditional latent class analysis.

Results

The results showed that the participants were divided into 5 profiles: a non-maltreatment profile; a profile of emotional abuse and emotional and physical neglect; a profile of physical neglect; a profile of emotional neglect; and a profile of physical and emotional neglect. Students with multiple subtypes of maltreatment had the highest levels of depression and anxiety.

Discussion

Universities should consider both childhood maltreatment and profiles of childhood maltreatment when training preschool education college students.

The influence of childhood trauma and chronotype on suicide attempts in Chinese emerging adults with severe depressive symptoms

BACKGROUND

Studies have investigated how adults with severe depressive symptoms are more likely to attempt suicide, and these adults often have traumatic experiences and chaotic sleep/wake rhythms. Thus, this study using Latent class analysis aimed to investigate the relationship between childhood trauma class, chronotype, and suicide attempts among emerging adults with severe depressive symptoms.

METHODS

This study was conducted among emerging adults with severe depressive symptoms covering 63 Universities in Jilin Province, China. A total of 1,225 emerging adults (mean age = 19.6 ± 1.78) constructed the final sample. In addition to measuring socio-demographic characteristics, the Childhood Trauma Questionnaire-Short Form, the Single-Item Chronotyping, and a single item for suicide attempts were used to evaluate childhood trauma, chronotype, and suicide attempts, respectively. Latent class analysis was applied to identify the classes of childhood trauma within emerging adults who had severe depressive symptoms. Hierarchical logistic regression models were run to investigate the effects of socio-demographic characteristics, chronotype, and childhood trauma class on suicide attempts.

RESULTS

Three latent classes were identified: the Low-risk for childhood trauma class, the Neglect class, and the High-risk for childhood abuse class. Those who suffered sexual, emotional, and physical abuse at the same time were divided into the High-risk for childhood abuse class, and were significantly more likely to experience suicide attempts than those in the Neglect class (OR = 1.97, 95%CI = 1.34-2.89, p < 0.001) and the Low-risk for childhood trauma class (OR = 2.28, 95% CI = 1.50-3.46, p < 0.001). In terms of chronotype, the results showed that the chaotic type was a risk factor for suicide attempts when compared with the evening type (OR = 0.46, 95%CI = 0.27-0.78, p < 0.01), the moderately active type (OR = 0.53, 95%CI = 0.31-0.89, p < 0.05), and the daytime type (OR = 0.42, 95%CI = 0.21-0.86, p < 0.05). Overall, the significant risk factors for suicide attempts included being female, living in an urban area, having experienced sexual, emotional, and physical abuse simultaneously, and having a chaotic chronotype.

CONCLUSION

Emerging adults suffering sexual, emotional, and physical abuse at the same time and identifying with chaotic chronotype showed a higher risk of attempting suicide. The findings provided a clinical reference to quickly identify those at high risk of suicide attempts among emerging adults with severe depressive symptoms.

Association between longitudinal patterns of child maltreatment experiences and adolescent substance use

BACKGROUND

Although there is a well-established link between child maltreatment and adolescent substance use, it remains unclear if and how longitudinal patterns of maltreatment experiences are associated with substance use in adolescence.

OBJECTIVE

The purpose of the study was to examine how distinct patterns of longitudinal maltreatment experiences are associated with adolescent substance use.

PARTICIPANTS AND SETTING

The participants were 899 adolescents from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN).

METHODS

We conducted repeated measures latent class analysis (RMLCA) to identify patterns of physical abuse, sexual abuse, and neglect from birth to age 17 and their relations to tobacco, alcohol, and marijuana use at age 18.

RESULTS

RMLCA identified three physical abuse classes (Stable low physical abuse; School age peak physical abuse; Physical abuse primarily in infancy/toddlerhood), two sexual abuse classes (Stable no/low sexual abuse; School age peak sexual abuse), and three neglect classes (High neglect in childhood; Neglect primarily in infancy/toddlerhood; Neglect primarily at school age). Adolescents in the school age peak physical abuse class showed greater alcohol, cigarette, and marijuana use, compared to other physical abuse classes. Similarly, adolescents in the school age peak sexual abuse class showed greater substance use than those in the stable no/low sexual abuse class. Lastly, adolescents in the neglect primarily in infancy/toddlerhood class showed significantly less substance use than those in the other two neglect classes.

CONCLUSIONS

Findings highlight the importance of early intervention and ongoing maltreatment prevention.

Maternal Childhood Abuse Versus Neglect Associated with Differential Patterns of Infant Brain Development

Severity of maternal childhood maltreatment has been associated with lower infant grey matter volume and amygdala volume during the first two years of life. A developing literature argues that effects of threat (abuse) and of deprivation (neglect) should be assessed separately because these distinct aspects of adversity may have different impacts on developmental outcomes. However, distinct effects of threat versus deprivation have not been assessed in relation to intergenerational effects of child maltreatment. The objective of this study was to separately assess the links of maternal childhood abuse and neglect with infant grey matter volume (GMV), white matter volume (WMV), amygdala and hippocampal volume. Participants included 57 mother-infant dyads. Mothers were assessed for childhood abuse and neglect using the Adverse Childhood Experiences (ACE) questionnaire in a sample enriched for childhood maltreatment. Between 4 and 24 months (M age = 12.28 months, SD = 5.99), under natural sleep, infants completed an MRI using a 3.0 T Siemens scanner. GMV, WMV, amygdala and hippocampal volumes were extracted via automated segmentation. Maternal history of neglect, but not abuse, was associated with lower infant GMV. Maternal history of abuse, but not neglect, interacted with age such that abuse was associated with smaller infant amygdala volume at older ages. Results are consistent with a threat versus deprivation framework, in which threat impacts limbic regions central to the stress response, whereas deprivation impacts areas more central to cognitive function. Further studies are needed to identify mechanisms contributing to these differential intergenerational associations of threat versus deprivation.

Childhood maltreatment and mental health problems in a 10-year follow-up study of adolescents in youth residential care: A latent transition analysis

Childhood maltreatment and mental health problems are common among young people placed out-of-home. However, evidence on the impact of maltreatment on the course of mental health problems in at-risk populations is sparse. The aim of this longitudinal study is twofold: (a) describe the course of mental health problems and the shift in symptom patterns among adolescents in youth residential care into young adulthood and (b) assess how childhood maltreatment is related to the course of mental health problems. One hundred and sixty-six adolescents in Swiss youth residential care were followed up into young adulthood (36.1% women; MAge-Baseline = 16.1 years; MAge-Follow-Up = 26.4 years). Latent transition analysis was employed to analyze transitions of symptom patterns and their association with maltreatment exposure. We found three latent classes of mental health problems: a "multiproblem"-class (51.8% baseline; 33.7% follow-up), a "low symptom"-class (39.2% baseline; 60.2% follow-up), and an "externalizing"-class (9.0% baseline; 6.0% follow-up). Individuals in the "multiproblem"-class were likely to transition towards less-complex symptom patterns. Higher severity of self-reported childhood maltreatment was associated with more complex and persistent mental health problems. Our study underlines the need for collaboration between residential and psychiatric care systems within and after care placements, with a specialized focus on trauma-informed interventions and care.

The co-occurrence of potentially traumatic events (PTEs) and their associations with posttraumatic stress disorder (PTSD) in Indian and Malaysian adolescents

BACKGROUND

Although it is well-established that people can experience multiple traumatic events, there are few studies examining the co-occurrence of such experiences in non-Western nations. The current study sought to examine the occurrence of multiple potentially traumatic experiences (PTEs) and their associations with posttraumatic stress disorder (PTSD) among adolescents from two Asian nations.

METHODS

Latent class analysis (LCA) was employed to model the co-occurrence of PTEs in two school samples of adolescents from India (n = 411) and Malaysia (n = 469). Demographic correlates (i.e., sex, age, household composition, parent education) of the latent classes and the association between latent class membership and probable diagnosis of posttraumatic stress disorder (PTSD) were examined.

RESULTS

The LCA identified three latent classes for the Indian sample: 'Low Risk - moderate sexual trauma', 'Moderate Risk', and 'High Risk'. Similarly, three classes were also identified for the Malaysian sample: 'Low Risk', 'Moderate Risk', and 'High Risk'. Membership of 'Moderate Risk' was associated with male sex in both samples, and with older age and lower levels of parental education attainment in the Malaysian sample. No correlates of 'High Risk' class were identified in either sample. Membership of the 'High Risk' class was significantly associated with probable PTSD diagnosis in both samples, while membership of the 'Moderate Risk' class was associated with probable PTSD diagnosis in the Malaysian sample.

CONCLUSION

Findings from this study correspond with Western studies indicating co-occurrence of PTEs to be common and to represent a salient risk factor for the development of PTSD.

Threat versus deprivation in mother's childhood: Differential relations to hair cortisol and psychopathology in pregnancy

BACKGROUND

The negative effects of childhood maltreatment can be intergenerational, and the prenatal period may play an important role in this intergenerational transmission. Maternal hypothalamic-pituitary-adrenal (HPA) axis dysfunction and maternal psychopathology represent two mechanisms through which the effects of childhood maltreatment are hypothesized to be transmitted across generations.

OBJECTIVE

This study first sought to extend prior research on pathways of intergenerational transmission by examining whether mothers' childhood experiences of abuse versus neglect differentially relate to maternal HPA activity and to maternal psychopathology during the prenatal period. Second, exploratory analyses examined the links between maternal variables and their State Protective Service involvement as a parent, as an indicator of maladaptive caregiving.

METHODS

During the third trimester of pregnancy, 51 women reported on experiences of childhood maltreatment, on State Protective Service involvement as an adult parent, and on current depressive and post-traumatic stress symptoms, and provided a hair sample for cortisol assay.

RESULTS

Regression analyses indicated that greater severity of abuse, but not neglect, in childhood was associated with higher maternal depressive symptoms (β = 0.488, p = .020). In contrast, greater severity of neglect, but not abuse, in mothers' childhood was associated with lower maternal hair cortisol concentration (β = -0.437, p = .031). Lower maternal hair cortisol concentration, but not maternal psychopathology or severity of childhood abuse or neglect, in turn, was associated with State Protective Service involvement (β = -0.785, p < .001).

CONCLUSIONS

Findings extend prior work by suggesting that childhood abuse and neglect may have different sequelae for mothers during pregnancy and that these sequelae may have different relations to parenting.

Heterogeneity In Women's Trauma Histories: Impact On Substance Use Disorder Severity

Trauma and substance use disorders (SUDs) frequently co-occur, especially in women. Previous studies have attempted to determine if individual differences in trauma histories could be meaningfully categorized but few studies have focused solely on women, especially those reporting substance use problems. A total of 130 women (M age = 30.7, SD = 7.9) self reporting past-year substance use problems completed comprehensive measures assessing lifetime exposure to a variety of traumatic events as well as substance use patterns and severity. Using latent class analysis, three classes emerged, a Low Lifetime Interpersonal Trauma class (40%, n = 52), a Moderate Lifetime Interpersonal Trauma class (23.8%, n = 31) and a High Lifetime Interpersonal Trauma class (36.2%, n = 47). Groups did not vary on daily/almost daily use of different types of substances and polysubstance use frequency but were significantly different on SUD severity, with the Moderate and the High Lifetime Interpersonal Trauma classes reporting severe SUD severity in comparison to moderate severity for the Low Interpersonal Trauma class. The findings of the current study indicate that women experiencing substance use problems should receive SUD treatment in a trauma-informed manner but that not all may require integrated trauma and substance use interventions.

Patterns and trajectories of children's maltreatment experiences in Taiwan: Latent transition analysis of a nationally representative longitudinal study

BACKGROUND

Little is known about the patterns of child maltreatment change over time and vary according to gender and child protective services (CPS) experience in Taiwan.

OBJECTIVE

To examine the latent status and the trajectories of child maltreatment and to identify effects that gender and CPS have on these statuses and trajectories in Taiwan.

PARTICIPANTS AND SETTING

A national proportionately stratified sample of 6233 4th-grade students were recruited from 314 elementary schools in Taiwan, and followed up at 6th and 8th graders. A total of 1908 students completed valid data at all three time points was analyzed.

METHODS

Latent class analysis and latent transition analysis were used to identify the number of latent variables and the patterns of child maltreatment. Multiple-group model was used to test with gender difference.

RESULTS

Four latent maltreatment statuses were identified: high all maltreatment, high psychological maltreatment, high neglect, and no/low maltreatment. A reduction in maltreatment severity occurred over time was found. The percentage of students in the "high all maltreatment" and "high neglect" groups decreased whereas those in the "high psychological maltreatment" and "no/low maltreatment" groups increased. Differences in the transition probabilities of latent maltreatment status by gender was revealed. The percentage of CPS recipients in the "high all maltreatment" decreased over time.

CONCLUSIONS

This study highlighted the dynamic nature of child maltreatment and described the timing, continuity, and change that characterizes children's exposure to maltreatment in Taiwan. Policies and interventions geared toward early detection, mitigation, and prevention of child maltreatment are needed.

A latent profile analysis of child maltreatment among at-risk youth gang members: Associations with violent delinquency, non-violent delinquency, and gang organizational structures

BACKGROUND

The relationship between child maltreatment and later delinquency is an enduring concern worldwide. However, the maltreatment-delinquency relationship is relatively underexplored in youth gang populations. Consequently, to date, studies have not examined typologies of maltreatment and their associations with violent delinquency, non-violent delinquency, and gang organizational structures.

OBJECTIVE

First, to identify the characteristics of subgroups of youth gang members who varied in abuse type and severity within type. Second, to determine in what ways the profiles differed in terms of gang organizational structures, violent delinquency, and non-violent delinquency.

PARTICIPANTS AND SETTINGS

A sample of 161 youth gang members (mean age: 16.8; range: 12-24) were recruited and surveyed by outreach social workers in Hong Kong.

METHODS

Latent profile analysis was first used to examine heterogeneity in victimization experiences (physical abuse, sexual abuse, emotional abuse, and neglect). Thereafter, non-parametric tests and post-hoc analyses were conducted to examine associations between the yielded typologies of maltreatment and gang organizational structures, violent delinquency, and non-violent delinquency.

RESULTS

Poly-victimization was prevalent in the sample, with 148 respondents (91.9 %) reporting at least two types of past abuses. Three profiles of maltreatment emerged, varying in abuse types and severity within types: 'Minimally maltreated', 'Moderately maltreated, except sexual abuse', and 'Severely maltreated'. In comparison to the 'Minimal' maltreatment profile, the 'Moderate' and 'Severe' profiles were associated with greater delinquent behaviors and being in gangs that encouraged congregate illegal behaviors.

CONCLUSIONS

There was a relationship between typologies of maltreatment and gang organizational structures, violent delinquency, and non-violent delinquency in the sample of youth gang members. Implications for practice and future research are discussed.

Validation of the "Darryl" PTSD Cartoon Test with Abused Children

Background

There is a lack of reliable and valid PTSD tests for young children that cannot read or are weak readers. The semi-projective cartoon test, "Darryl", which is read aloud, is a measure that appeals to this age group. The test has been applied in both clinical and epidemiological studies.

Objective

to validate a cartoon test, "Darryl", for children aged 6 or older in a population of children suspectedly sexually and/or physically abused.

Methods

In the Danish Child Centres, 327 children were screened with Darryl as part of an assessment for further intervention. The Bech Youth Inventory was filled out by 113 children, and 63 caregivers filled out the Strengths & Difficulties Questionnaire. Correlations were used to study the convergent validity between the scales and subscales and effect sizes were estimated. Reliability of the scales was investigated using Cronbach's alpha.

Results

Following the DSM-IV, 55.7% of the children (n = 182) had a possible PTSD diagnosis. More girls (n = 110, 62.9 %) than boys (n = 72, 47.4%) had PTSD. A total of 21.7 % (n = 71) had subclinical PTSD, lacking only one symptom of the full diagnosis. There was no significant difference in PTSD regarding physical or sexual abuse.

Clinical significance

The test allows clinicians in the pediatric field to screen for possible PTSD in a population where systematic self-report data have paramount importance.

Conclusions

Darryl appears to be a valid and reliable test for screening young children who have been physically or sexually abused. The test is helpful for clinician working with young children to identify those have developed trauma symptoms to secure them early treatment.

A Hierarchical Cluster Analysis of Childhood Interpersonal Trauma and Dispositional Mindfulness: Heterogeneity of Sexual and Relational Outcomes in Adulthood

The current mixed-method study aimed to 1) identify different childhood interpersonal trauma (CIT) and dispositional mindfulness (DM) profiles in an adult sample; 2) illustrate these profiles with qualitative data documenting childhood sexual abuse (CSA) and CIT survivors' perceptions of their own DM; and 3) examine profile differences on sexual and relational outcomes. Participants were 292 adults who completed an online questionnaire. A subsample of participants having reported a history of CSA (n = 51) also completed semi-structured interviews. Hierarchical cluster, comparison, and content analyses were performed. Analyses yielded three profiles: 1) Lower victimization, high mindfulness; 2) Psychological victimization, low mindfulness; and 3) Multi-victimization, low mindfulness. Participants in profile 1 presented the lowest frequency of CIT experiences and the highest levels of DM and sexual and relational well-being. Profile 2 participants presented higher sexual and relational well-being (i.e., higher sexual satisfaction, lower sexual depression, and fewer interpersonal conflicts) than those in profile 3. By documenting distinct CIT and DM profiles and tying them to different levels of relational and sexual well-being, this study could guide practitioners in designing tailored interventions.

The nature and extent of child maltreatment in Denmark: Using self-report and administrative data from the 1984 birth cohort

BACKGROUND

Research on child maltreatment (CM) has few longitudinal studies that combine self-report data with objective administrative data that has been collected continuously for decades.

OBJECTIVE

To give an overview of 20 studies investigating the impact of CM in a Danish representative sample.

PARTICIPANTS AND SETTING

From the full 1984 Danish birth cohort, 2980 24-years old were randomly selected. There was an oversampling of child protection cases.

METHODS

The participants were interviewed by trained interviewers and Computer Assisting Methods were used for sensitive topics. The survey data were linked to several national registers using the Civil Registry Number for a series of studies on risk factors and outcomes. Linkage with parental data enabled parental risk factors before the birth to be analysed as well as several physical, psychological, and social events during their lifetime. These factors were studied in relation to the CM classes that were identified via the survey.

RESULTS

The maltreatment classes had both several specific and shared effects pertaining to risk factors before birth, during childhood through to early adulthood. Their problems included many arenas within health, mental and social life.

CONCLUSIONS

Data linkage studies provide an opportunity to conduct research using accurate sources of information which can be used to explore risk and protective factors. The prospective nature of this combined data facilitates temporal ordering which strengthen the conclusions based on longer-term follow-up.

Maltreatment Type Classifications and Transitions During Childhood for a California Birth Cohort

Childhood maltreatment involves dynamics between the type of maltreatment experienced and the context of maltreatment. Reports of alleged maltreatment to child protective services may overlap and shift over time, complicating understanding of their independent and interacting nature, including how child protection systems respond. Latent class analysis (LCA) and latent transition analysis (LTA) were used to construct data-based models of longitudinal dynamics of alleged maltreatment throughout childhood. We sought to identify patterns leading to system decisions to substantiate allegations of maltreatment and place children in foster care. Using linked birth and child protection records, we defined a cohort of children born in California in 1999, 29.4% of whom had at least one referral for alleged maltreatment before their 18th birthday. Maltreatment and perpetrator indicators were coded, and LCA identified five alleged maltreatment classes and one class of children without referrals. LTA determined consistency of classifications and estimated transitions between classes over age periods. Children with multitype maltreatment patterns or experiences of neglect were most likely to experience future maltreatment allegations. Estimated probabilities of placement indicated children with Multitype Maltreatment allegations were more likely to experience substantiated maltreatment allegations and out-of-home placements. Findings identify a repeatable method for better understanding complex systems.

Patterns of adversity and post-traumatic stress among children adopted from care

BACKGROUND

Children adopted from care are more likely to have experienced early adversity, but little is known about the impact of early adversity on later post-traumatic stress (PTS) symptoms.

OBJECTIVE

To investigate sub-groups of adversity in a sample of adopted children and examine the association with later PTS symptoms.

PARTICIPANTS AND SETTING

A study of British children adopted from care using social worker records (N = 374) and questionnaire-based longitudinal study of n = 58 children over 4-years post adoptive placement.

METHODS

We used latent class analysis to identify subgroups of children based on commonalities in perinatal and postnatal adversity experienced prior to adoption and examined differences in PTS symptoms at 4-years post-placement between subgroups.

RESULTS

Nearly one in five (19 %) children were in the clinical or borderline ranges for symptoms of PTS arousal, 14 % for PTS avoidance and 8 % for PTS intrusion. The 5-class solution fitted the data best, with one class characterized by children with a low probability of experiencing any adversity, one perinatal adversity class and three classes capturing different patterns of adversity. The multiple complex adversity class involving both perinatal and postnatal adversity had significantly higher symptoms of PTS avoidance and arousal than other sub-groups.

CONCLUSIONS

The prevalence and complexity of PTS symptoms among adoptive children highlights the need for effective interventions considering different profiles of early adversity.

Patterns of Maternal Childhood Maltreatment and Disrupted Interaction Between Mothers and Their 4-Month-Old Infants

Maternal childhood maltreatment (MCM) is associated with parenting disruptions which may contribute to the intergenerational transmission of negative health and social outcomes. Most prior work has used variable-centered approaches to assess MCM. Complementary person-centered approaches can identify groups of participants characterized by similar patterns of maltreatment. The current study assessed both types and patterns of MCM in relation to disrupted parenting among 179 mothers and their 4-month-olds. In variable-centered analyses, physical abuse was related to negative-intrusive maternal behavior and physical neglect to role-confused behavior. Person-centered analyses derived three classes of MCM, which differed in disrupted parenting. For example, mothers who experienced multiple types of maltreatment displayed more withdrawal than mothers in both other classes. Results document the differential effects of particular types and patterns of MCM on aspects of parenting and reveal that mother's history of maltreatment can affect the quality of mother-child interaction as early as 4 months of age.

Heterogeneous adverse childhood experiences and cognitive function in an elderly Chinese population: a cohort study

OBJECTIVE

To identify the heterogeneity of adverse childhood experiences (ACEs) as well as their association with cognitive function in an elderly Chinese population.

DESIGN

A retrospective cohort study.

PARTICIPANTS

The data were from the latest wave of the China Health and Retirement Longitudinal Study and a total of 7222 participants aged ≥60 were included.

PRIMARY AND SECONDARY OUTCOME MEASURES

Latent class analysis was used to identify the classes characterised by 11 types of ACEs. Cognitive function was measured by the Mini-Mental State Examination (MMSE) and cognitive impairment was defined by education-specific threshold MMSE scores. Logistic models were constructed to examine the relationship between ACE classes and cognitive impairment. Several childhood and adulthood confounding factors were considered.

RESULTS

Three ACE latent classes were identified. Of them, 76.09% were in the 'Low ACEs' class, 15.43% were in the 'Household dysfunction' class and 8.49% were in the 'Child maltreatment' class. The people in the 'Low ACEs' class seemed to have better childhood family financial situations and higher education levels. The population in the 'Household dysfunction' class tended to live in rural areas and have a higher proportion of men, whereas people in the 'Child maltreatment' class showed a significantly higher proportion of women and higher levels of chronic diseases. 'Child maltreatment' was related to a higher risk of cognitive impairment (OR=1.37, 95% CI: 1.12 to 1.68), while the risk of 'Household dysfunction' was not significantly different from that of the 'Low ACEs' participants (OR=1.06, 95% CI: 0.90 to 1.26).

CONCLUSIONS

The findings supported differences in cognitive function in elderly Chinese people exposed to different types of ACEs.

Stressful Events and Adolescent Psychopathology: A Person-Centred Approach to Expanding Adverse Childhood Experience Categories

Stress from cumulative adverse childhood experiences (ACEs) can pose a serious risk of experiencing anxiety, depression, and other mood disorders in adolescence. However, there is a paucity of research identifying specific profiles or combinations of exposure to other forms of stressful life events and their impact on adolescent psychopathology. This study attempted a conceptual expansion of the ACE checklist by examining these stressful events. The study used cross-sectional data from a modified version of the CASE Study survey where 864 adolescents (56% female, n = 480), aged from 11 - 18 years were recruited from four post-primary schools in the North-West region of NI. Latent class analysis of the 20-item stressful events checklist revealed 3 distinct risk classes: a low-risk class (53.5%), at-risk class (42.7%), and an immediate-risk class (3.8%). Results showed those at most risk of adolescent psychopathology had the highest probability of encountering interpersonal relationship issues, experiencing family dysfunction, and having close friends experiencing psychological difficulties. Findings indicate that the original ten ACE categories may be too narrow in focus and do not capture the wide range of childhood adversity. Expanding the ACE checklist to include other stressful events is discussed as these may also be antecedents to psychopathologic responses.

Cumulative risk, factor analysis, and latent class analysis of childhood adversity data in a nationally representative sample

BACKGROUND

Childhood adversity is a multifaceted construct that is in need of comprehensive operationalisation.

OBJECTIVE

The aim of this study was to explore the optimal method to operationalise a scale of adverse childhood experiences (ACEs).

PARTICIPANTS AND SETTING

Data were from Wave 1 of the Personality and Total Health (PATH) Through Life Project (N = 7485, 51% women). Participants from three age groups (20-25, 40-45, 60-65) retrospectively reported their childhood experiences of domestic adversity on a 17-item scale (e.g., physical abuse, verbal abuse, neglect, poverty).

METHODS

We compared three approaches to operationalising the 17-item scale: a cumulative risk approach, factor analysis, and latent class analysis (LCA). The cumulative risk and dimensional models were represented by a unidimensional and two-dimensional model respectively using confirmatory factor analysis (CFA).

RESULTS

The cumulative risk approach and LCA were viable approaches to operationalising ACE data in PATH. CFA of the dimensional model produced latent factors of threat and deprivation that were highly correlated, potentially leading to problems with multicollinearity when estimating associations. LCA revealed six classes of ACEs: high adversity, low adversity, low affection, authoritarian upbringing, high parental dysfunction, and moderate parental dysfunction.

CONCLUSION

Our study found multiple latent classes within a 17-item questionnaire assessing domestic adversity. Using both the cumulative method and latent class approach may be a more informative approach when examining the relationship between ACEs and later health outcomes. Future ACE studies may benefit by considering multi-dimensional approaches to operationalising adversity.

Adverse experiences and mental health problems in perpetrators of intimate partner violence in Northern Ireland: A latent class analysis

BACKGROUND

Trauma and adverse experiences among perpetrators of intimate partner violence (IPV) have been associated with more serious patterns of offending.

OBJECTIVE

To examine 1) how traumatic and adverse experiences cluster together and co-occur among IPV perpetrators, and 2) whether different patterns of trauma exposure are associated with specific mental health problems.

PARTICIPANTS AND SETTING

The sample consisted of 405 convicted IPV perpetrators from Northern Ireland.

METHODS

Data was collected between 2018 and 2019. Latent class analysis identified typologies of exposure to traumatic and adverse experiences. A series of binary logistic regression analyses explored associations between the identified classes and five categories of probable mental health problems.

RESULTS

Three adversity classes were identified: a baseline class (59.2%), characterised by relatively low levels of exposure to most types of adversity; a 'childhood adversity' class (32.9%), with high levels of childhood adversity; and a 'community violence and disadvantage' class (7.9%), which had high probabilities of endorsing adversities related to economic hardship and community violence. Regression analyses showed that the childhood adversity class was significantly associated with increased likelihood of all categories of mental health problems, except for neurodevelopmental disorders (ORs = 1.77-3.25). The community violence and disadvantage class was significantly associated with probable mood and anxiety disorder (ORs 3.92 and 8.42, respectively).

CONCLUSIONS

Different patterns of exposure to adversities were associated with distinct mental health problems in the present sample. Early intervention to prevent poly-victimisation, the clustering of adversities in childhood and the resulting accumulation of risk may be a useful component of preventive responses for IPV in Northern Ireland.

Characterizing Typologies of Polytraumatization: A Replication and Extension Study Examining Internalizing and Externalizing Psychopathology in an Urban Population

A person-centered approach to examining trauma has uncovered typologies of polytraumatization that are differentially associated with psychopathology. However, previous research is limited by narrow conceptualizations of trauma, limited distal outcomes, and underrepresentation of minorities. To address these gaps, we used latent profile analyses to uncover distinct polytraumatization typologies and examine four symptom-based (PTSD, depression, aggression, and substance abuse) and two behavior-based (self-harm, jail counts) outcomes in a sample of low-income adults (n = 7,426, 94% African American). The models were indicated by 19 traumatic experiences (e.g., accident, sexual assault, witnessing/experiencing violence). The best fitting model uncovered five classes: minimal trauma, physical abuse, violence exposure, sexual abuse, and polytrauma. Classes characterized by significant and varied trauma were higher on both internalizing and externalizing psychopathology, while those characterized by specific types of trauma were only higher on one type of psychopathology. Implications for the assessment and treatment of trauma-related disorders are discussed.

A latent class analysis of physical, emotional, and sexual abuse history among suicidal inpatients

OBJECTIVE

Physical, emotional, and sexual abuse are subtypes of childhood abuse that may persist into adulthood. This study applied latent class analysis to describe the pattern of co-occurrence of these three abuse subtypes during childhood and adulthood and examined latent class differences in psychosocial characteristics and three types of suicide attempt history (aborted, interrupted, and actual).

METHODS

Data were drawn from a high-risk sample of 115 military service members and adult beneficiaries who were psychiatrically hospitalized following a suicide-related crisis.

RESULTS

Three latent classes were identified: Multiple and Persistent Abuse (Class One: 29.6%), Childhood Physical and Persistent Emotional Abuse (Class Two: 27.0%), and Minimal Abuse (Class Three: 43.5%). Females were more likely than males to report a history of Multiple and Persistent Abuse. After controlling for gender, the Multiple and Persistent Abuse Class had higher scores of depressive symptoms and hazardous drinking, poorer sleep quality, and increased social stress than the Minimal Abuse Class. Moreover, the Multiple and Persistent Abuse Class was associated with increased likelihood of lifetime interrupted suicide attempt (Odds Ratio [OR] = 3.81, 95% CI = 1.20, 12.07) and actual suicide attempt (OR = 3.65, 95% CI = 1.23, 10.85), and had the greatest number of total actual suicide attempt (1.82 times on average).

CONCLUSION

Co-occurrence of multiple subtypes of abuse across development is associated with higher psychosocial risk and history of suicide attempt. The assessment of specific subtypes of abuse and their timing may inform case conceptualization and the management of suicide risk among psychiatric inpatients.

Profiles of Childhood Maltreatment: Associations with Sexual Risk Behavior during Adolescence in a Sample of Racial/Ethnic Minority Girls

This study examines associations between childhood maltreatment and developmental trajectories of sexual risk behaviors (SRBs) in a sample of 882 sexually active adolescent girls, predominantly Hispanic or Black, assessed every 6 months between 13 and 23 years. Latent profile analyses revealed four distinct maltreatment profiles: Low Maltreatment (76%), Moderate Emotional Neglect Only (15%), Severe Physical/Emotional Abuse (3%), and Severe Sexual Abuse (6%). Multilevel growth analyses showed the Moderate Emotional Neglect Only and Severe Sexual Abuse profiles exhibited more SRBs starting in late adolescence, and the Severe Sexual Abuse profile also exhibited a faster increase than the Low Maltreatment profile. Understanding heterogeneity within maltreated populations may have important implications for healthy sexual development.

Child Maltreatment and Disordered Eating in Adulthood: a Mediating Role of PTSD and Self-Esteem?

The current study investigated relationships between different experiences of child maltreatment (CM) and disordered eating (DE) in a large population-based sample of Danish young adults. Participants completed a structured interview comprising socio-demographic, psychological and physical domains. Questions regarding CM, DE, PTSD symptoms and self-esteem were analyzed using chi-square-tests, ANOVAs, hierarchical regression, and multiple mediation analyses. Participants with a history of CM experienced higher levels of DE than non-abused individuals. PTSD symptoms and self-esteem appeared to differentially mediate the relationship between three classes of CM and DE. Whereas the relation between emotional and sexual abuse with DE was partially mediated via participants' level of PTSD symptoms and self-esteem with emotional abuse having a stronger impact on self-esteem and sexual abuse more strongly influencing PTSD symptoms, the relation between polyvictimization and DE was fully mediated by PTSD and self-esteem, mainly due to the indirect effect via PTSD.

Child Maltreatment Typologies and Intimate Partner Violence: Findings From a Danish National Study of Young Adults

The association between exposure to childhood maltreatment and subsequent intimate partner violence (IPV) has been well documented. Recently, there has been increased attention to IPV in adolescence and young adulthood, with studies demonstrating that IPV peaks in young adulthood. Data were collected from a Danish national study conducted by The Danish National Centre for Social Research in 2008 and 2009. A sample of 4,718 young adults (aged 24) was randomly selected using the total birth cohort of children born in 1984. Structured interviews were conducted with 2,980 participants equating to a response rate of 63%. Childhood maltreatment including emotional, sexual, and multiple abuse experiences and being female and a young parent were used to test the association with experiencing IPV victimization. Bivariate associations showed that all variables were significantly associated with experiencing IPV. When the variables were entered into a multivariate binary logistic regression analysis, being female indicated the strongest association (odds ratio [OR] = 13.96), followed by experiencing childhood sexual abuse (OR = 10.90) and experiencing multiple types of abuse (OR = 6.49). Results suggest that among the child maltreatment typologies, sexual abuse is the dominant factor associated with IPV. The current study extends the literature conducted on a young adult population by demonstrating that early adverse experiences and being female and a parent are associated with IPV in young adulthood. These findings suggest prevention programs should be targeted in early adolescence to support young people to establish and maintain positive and healthy relationships that promote safe conflict resolution strategies.

Modeling Patterns of Polyvictimiztion and Their Associations with Posttraumatic Stress Disorder and Complex Posttraumatic Stress Disorder in the Israeli Population

Although evidence is accumulating for the conceptual validity of the ICD-11 proposal for posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD), our understanding of the specificity of trauma-related predictors is still evolving. Specifically, studies utilizing advanced statistical methods to model the association between trauma exposure and ICD-11 proposals of traumatic stress and differences in profiles of trauma exposure are lacking. Additionally, time since trauma and a clear memory of the trauma are yet to be examined as predictors of PTSD and CPTSD. We analyzed trauma exposure as reported by a general population sample of Israeli adults (N = 834), using latent class analysis, and the resultant classes were used in regression models to predict PTSD and CPTSD operationalized both dimensionally and categorically. Four distinct groups were identified: child and adult interpersonal victimization, community victimization-male, community victimization-female, and adult victimization. These groups were differentially related to PTSD and CPTSD, with only child and adult interpersonal victimization consistently predicting CPTSD and disturbances in self-organization. When modeled dimensionally, PTSD was associated with the child and adult interpersonal victimization and adult victimization groups, whereas only the child and adult interpersonal victimization group was predictive of PTSD when operationalized categorically. The roles of time since trauma and a clear memory of the trauma differed across PTSD and CPTSD. These findings support the use of trauma typologies for predicting PTSD and CPTSD and provide important insight into the distribution of trauma exposure in the Israeli population.

Associations between childhood maltreatment latent classes and eating disorder symptoms in a nationally representative sample of young adults in the United States

BACKGROUND

Childhood maltreatment is associated with eating disorders, but types of childhood maltreatment often co-occur.

OBJECTIVE

To examine associations between childhood maltreatment patterns and eating disorder symptoms in young adulthood.

PARTICIPANTS AND SETTING

Data came from the National Longitudinal Study of Adolescent to Adult Health (N = 14,322).

METHODS

Latent class analysis was conducted, using childhood physical neglect, physical abuse, and sexual abuse as model indicators. Logistic regression models adjusted for demographic covariates were conducted to examine associations between childhood maltreatment latent classes and eating disorder symptoms.

RESULTS

In this nationally representative sample of U.S. young adults (mean age = 21.82 years), 7.3% of participants reported binge eating-related concerns, 3.8% reported compensatory behaviors, and 8.6% reported fasting/skipping meals. Five childhood maltreatment latent classes emerged: "no/low maltreatment" (78.5% of the sample), "physical abuse only" (11.0% of the sample), "multi-type maltreatment" (7.8% of the sample), "physical neglect only" (2.1% of the sample), and "sexual abuse only" (0.6% of the sample). Compared to participants assigned to the "no/low maltreatment" class, participants assigned to the "multi-type maltreatment" class were more likely to report binge eating-related concerns (odds ratio = 1.97; 95% confidence interval [CI]: 1.52, 2.56) and fasting/skipping meals (OR = 1.85; 95% CI: 1.46, 2.34), and participants assigned to the "physical abuse only" class were more likely to report fasting/skipping meals (OR = 1.35; 95% CI: 1.04, 1.76).

CONCLUSIONS

This study provides evidence that distinct childhood maltreatment profiles are differentially associated with eating disorder symptoms. Individuals exposed to multi-type childhood maltreatment may be at particularly high risk for eating disorders.

Genetic Vulnerability to Experiencing Child Maltreatment

Although biological factors may influence the risk of experiencing negative life events, the role of genes in the vulnerability to child victimization remains poorly understood. In a large population-based Finnish sample (N = 13,024), we retrospectively measured multiple experiences of child victimization and, in a subsample of twins (n = 9,562), we estimated the extent to which genetic and environmental factors influenced these experiences. In particular, we investigated whether genetic and environmental influences varied depending on the type of child victimization, the genetic relatedness with the perpetrator, and the sex of the victim. Our quantitative genetic analyses supported the presence of both genetic and environmental influences on the occurrence and co-occurrence of child abuse and neglect. We also identified one common etiological pathway underlying multiple child victimizations, and after accounting for this common etiology, we singled out risk factors specific to sexual abuse. Environmental factors shared and nonshared between twins raised together influenced the risk of victimization by genetically related and unrelated perpetrators, respectively. Furthermore, we estimated sex differences in the etiology of emotional and sexual victimization, including larger unshared environmental influences for men and sex-limited genetic effects for women. These findings can inform child protection as they contribute to explaining why certain individuals are at increased risk of experiencing one or more types of child maltreatment.

Where are all the males? Gender-specific typologies of childhood adversity based on a large community sample

BACKGROUND

Methodological issues have been identified when quantifying exposure to adversity and abuse. To address a single type may obscure covarying effects. To sum multiple exposures gives equal weight to each. Latent class analysis (LCA) addresses this by identifying homogenous subpopulations. Most studies using LCA have pooled gender data in spite of evidence that the nature and frequency of exposure differs by gender. Males report more interpersonal abuse, females report more of other exposures, particularly sexual.

OBJECTIVE

This study aimed to identify if stratifying data by gender resulted in different profiles of adversity/abuse Participants and setting: The National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) wave II, a large community-based survey, nationally representative of the US population.

METHOD

This study used 14 indicators of childhood adversity as the basis for LCA.

RESULTS

The number and nature of classes differed by gender. The best solution for females was 4-class: a low risk class; a class at higher risk of sexual abuse; a class at higher risk of physical abuse; a class at higher risk of combined physical and sexual abuse. The best solution for males had only 3-classes; a low risk class, a class at higher risk of sexual abuse; a class at higher risk of physical abuse. The combined dataset resulted in a solution similar to the female solution.

CONCLUSION

The importance of developing models for males and females separately was evidenced by the male and female classes being differentially associated with mental health variables.

Childhood sexual abuse, poly-victimization and internalizing disorders across adulthood and older age: Findings from a 25-year longitudinal study

BACKGROUND

We aimed to investigate associations between childhood sexual abuse and maltreatment and internalizing disorders (anxiety, depression, PTSD) across adulthood.

METHODS

Following a postal survey of 2220 women, a subsample was selected to participate in an interview. The subsample included 276 women reporting childhood sexual abuse and 221 women with no reported history of childhood sexual abuse. Interviews were repeated six and 25 years following the first interview. Internalizing disorders were assessed using ICD-8 and DSM-III criteria.

RESULTS

There was a lower probability of having an internalizing disorder at older ages than younger ages for all women, regardless of maltreatment history. Latent class analysis was used to define three classes (no/low maltreatment, sexual abuse, poly-victimisation). Compared with no/low maltreatment, a history of childhood sexual abuse was associated with almost double the risk of an internalizing disorder and a history of poly-victimisation was associated with over four times the risk of an internalizing disorder. Childhood sexual abuse and poly-victimisation remained associated with an elevated risk of a disorder in older age.

LIMITATIONS

Findings are limited by attrition (39% participated at Time 3), low prevalence of severe physical abuse, and changes in assessment practice of childhood maltreatment and mental disorder in the past 30 years.

CONCLUSIONS

Screening and treatment for internalizing disorders in women with histories of childhood maltreatment remains important in older aged populations.

An examination of child protective service involvement among children born to mothers in foster care

OBJECTIVE

This study identified children born to mothers in foster care and documented Child Protective Service (CPS) involvement among children.

METHODS

Probabilistically linked birth and CPS records from California (2009-2012) were used to identify all mothers in foster care on or after conception. Children were followed prospectively using linked records to identify CPS involvement occurring during the first three years of life. Differences between reported and unreported children were examined using χ2 tests. The Latent Class Analysis (LCA) identified classes of children born to mothers in care who were at increased risk of CPS involvement. Model fit was assessed using the Bayesian Information Criterion, entropy, and likelihood ratio tests. For each of the classes, the relationship to the distal outcome (i.e., a maltreatment report by age three), was examined.

RESULTS

Findings indicate that 53% of children born to mothers in care were reported. The proportion of children reported to CPS for maltreatment declined over time, from 63% of children born to mothers in foster care in 2009, to 46% in 2012. The LCA documented three distinct classes of mother-child dyads with varying risk of report. More than one third of children in Class 1 and nearly 70% of children in Class 3 were reported.

CONCLUSIONS

This study was the first to develop multi-dimensional class profiles of two-generation CPS involvement among mother-child dyads. This study documents that mothers' experiences in care and mental health conditions vary widely, underscoring the importance of providing services that fit the needs of dyads.

Identifying maltreatment subgroups with patterns of maltreatment subtype and chronicity: A latent class analysis approach

Maltreatment experiences are complex, and it is difficult to characterize the heterogeneity in types of maltreatment. Subtypes, such as emotional maltreatment, sexual abuse, physical abuse, and neglect commonly co-occur and may persist across development. Therefore, treating individual maltreatment subtypes as independently occurring is not representative of the nature of maltreatment as it occurs in children's lives. Latent class analysis (LCA) is employed herein to identify subgroups of maltreated children based on commonalities in maltreatment subtype and chronicity. In a sample of 674 low-income urban children, 51.6% of whom experienced officially documented maltreatment, our analyses identified four classes of children, with three distinct classes based on maltreatment subtypes and chronicity, and one group of children who did not experience maltreatment. The largest class of maltreated children identified was the chronic, multi-subtype maltreatment class (57% of maltreated children); a second class was characterized by only neglect in a single developmental period (31% of maltreated children), and the smallest class was characterized by a single subtype of maltreatment (emotional maltreatment, physical, or sexual abuse) occurring in a single developmental period (12% of maltreated children). Characterization of these groups confirms the overlapping nature of maltreatment subtypes. There were notable differences between latent classes on child behavioral and socio-emotional outcomes measured by child self-report and camp counselors report during a one-week summer camp. The largest differences were between the non-maltreated class and the chronic maltreatment class. Children who experienced chronic, multi-subtype maltreatment showed higher levels of externalizing behavior, emotion dysregulation, depression, and anxiety.

The co-occurrence of adverse childhood experiences among children investigated for child maltreatment: A latent class analysis

Children investigated for maltreatment are particularly vulnerable to experiencing multiple adversities. Few studies have examined the extent to which experiences of adversity and different types of maltreatment co-occur in this most vulnerable population of children. Understanding the complex nature of childhood adversity may inform the enhanced tailoring of practices to better meet the needs of maltreated children. Using cross-sectional data from the National Survey of Child and Adolescent Well-Being II (N=5870), this study employed latent class analysis to identify subgroups of children who had experienced multiple forms of maltreatment and associated adversities among four developmental stages: birth to 23 months (infants), 2-5 (preschool age), 6-10 (school age), and 11-18 years-old (adolescents). Three latent classes were identified for infants, preschool-aged children, and adolescents, and four latent classes were identified for school-aged children. Among infants, the groups were characterized by experiences of (1) physical neglect/emotional abuse/caregiver treated violently, (2) physical neglect/household dysfunction, and (3) caregiver divorce. For preschool-aged children, the groups included (1) physical neglect/emotional abuse/caregiver treated violently, (2) physical neglect/household dysfunction, and (3) emotional abuse. Children in the school-age group clustered based on experiencing (1) physical neglect/emotional neglect and abuse/caregiver treated violently, (2) physical neglect/household dysfunction, (3) emotional abuse, and (4) emotional abuse/caregiver divorce. Finally, adolescents were grouped based on (1) physical neglect/emotional abuse/household dysfunction, (2) physical abuse/emotional abuse/household dysfunction, and (3) emotional abuse/caregiver divorce. The results indicate distinct classes of adversity experienced among children investigated for child maltreatment, with both stability across developmental periods and unique age-related vulnerabilities. Implications for practice and future research are discussed.

The trauma factor: Examining the relationships among different types of trauma, dissociation, and psychopathology

Extensive research has reported a dose-response relationship between exposure to trauma and the severity of both dissociation and psychopathology. However, certain types of trauma may co-occur more frequently than others and specific combinations of traumatic experiences may relate differently to dissociative processes and psychiatric symptoms. In the current study, 359 adult participants completed questionnaires on traumatic experiences, dissociation, and psychopathology. A correlation network analysis showed that some types of trauma are more likely to co-occur and that especially traumatic experiences in attachment relationships during childhood were significantly associated with other trauma in life. A latent class analysis identified four classes of participants (namely, extremely traumatized, resilient to the impact of abuse, exposed to impersonal and social trauma, and reporting low levels of traumatization) who showed different profiles on trauma exposure, dissociation, and psychopathology. Mediation analyses further showed that dissociation partially mediated the relationship between different types of traumatic experiences and the severity of psychiatric symptoms. The findings of this study support the view that a comprehensive assessment of traumatic experiences and dissociation is needed in trauma research and clinical practice.

Profiles and behavioral consequences of child abuse among adolescent girls and boys from Barbados and Grenada

The current study used latent class analysis to uncover groups of youths with specific abuse (physical, emotional, and sexual) profiles in and outside the family, and identify how membership in each abuse group is associated with behavioral outcomes. Data were collected among a sample of male (n = 662; M_age = 13.02 years) and female (n = 689; M_age = 12.95 years) children and adolescents (9-17 years old) from Barbados and Grenada. Self-report surveys were completed by participants in school settings. Three latent classes of child abuse were distinguished among boys, including 'low abuse' (39.2% of the sample), 'physical and emotional abuse high outside/medium in the family' (43.2%), and 'high overall abuse' (17.6%). Among girls, four unique classes were recovered: 'low abuse' (40.7%), 'high physical and emotional abuse outside the family' (7.6%), 'high emotional and moderate physical abuse' (33.9%), and 'high overall abuse' (17.8%). Compared with members of low abuse groups, youths who reported having experienced high/moderate levels of various forms of violence, including those who were abused in multiple ways and across the two settings ('high overall abuse'), were significantly more likely to engage in violent and hostile behavior. Abused and non-abused youths did not differ on non-violent conflict resolution skills. The significance of present findings for future research and practice is discussed.

Family profiles of maltreated children in Singapore: A latent class analysis

Children who enter the child protection system often have complex family problems and have experienced early adverse experiences. Using latent class analysis, this study aimed to identify family classes of child protection cases in Singapore, to ascertain the prevalence of these family classes, and to test the association of family class membership to subsequent recurrence of harm. A sample of 440 cases who entered the Child Protective Service in Singapore was analyzed based on eight familial factors on the household and caregiver levels. A four-class solution was found to demonstrate the best fit: (a) the large household group was intergenerational and majority lived with extended family members, (b) the harsh parenting group showed high levels of parenting problems and the caregiver justifying his abuse/neglect, (c) the high criminality group had high levels of caregiver substance abuse and caregiver arrest and incarceration history, and (d) the low disadvantage group rated low on all the familial factors. A Cox Regression revealed that in comparison to the low disadvantage group, the harsh parenting group was twice as likely to have recurrence of harm. There were also differences across family classes with regard to age at entry into child protection, gender composition and abuse types. The findings and practice implications are discussed.

The moderating impact of childhood adversity profiles and conflict on psychological health and suicidal behaviour in the Northern Ireland population

Childhood adversities are key etiological factors in the onset and persistence of psychopathology. In Northern Ireland the Troubles also impacted on the population's psychological health. This study used data from the Northern Ireland Study of Health and Stress a collaborative epidemiological study which used the WMH-CIDI to assess mental health disorders in a nationally representative sample (Part 2, n = 1986). The aims of the study were to assess co-occurrences of childhood adversities and investigate the impact of adversity profiles and conflict experience on psychopathology and suicidal behaviour. Latent Class Analysis uncovered 3 discrete childhood adversity profiles, a low, medium, and high risk class. Individuals from higher risk adversity profiles displayed significantly increased odds of having psychological problems, with conflict exposure also impacting on psychopathology. However, the study revealed that the impact of conflict exposure on suicidal behaviour was moderated by latent class membership and that some adversity may actually be protective. The findings highlight the need to consider that, while adversity can have a negative impact on psychopathology, a lack of adversity early in life may hinder some people from developing adequate coping strategies. Further research is required to identify adversity patterns and other interacting factors that are protective.

Patterns of psychological health problems and family maltreatment among United States Air Force members

OBJECTIVES

We sought to identify subgroups of individuals based on patterns of psychological health problems (PH; e.g., depressive symptoms, hazardous drinking) and family maltreatment (FM; e.g., child and partner abuse).

METHOD

We analyzed data from very large surveys of United States Air Force active duty members with romantic partners and children.

RESULTS

Latent class analyses indicated six replicable patterns of PH problems and FM. Five of these classes, representing ∼98% of survey participants, were arrayed ordinally, with increasing risk of multiple PH problems and FM. A sixth group defied this ordinal pattern, with pronounced rates of FM and externalizing PH problems, but without correspondingly high rates/levels of internalizing PH problems.

CONCLUSIONS

Ramifications of these results for intervention are discussed.

How Childhood Maltreatment Profiles of Male Victims Predict Adult Perpetration and Psychosocial Functioning

This study used latent class analysis to empirically identify subgroups of men based on their exposure to childhood maltreatment (i.e., emotional neglect and abuse, physical neglect and abuse, and sexual abuse). It then examined subgroups' differential perpetration of adult intimate partner violence (IPV; both psychological and physical), violence against peers, and sexual assault. Finally, we compared sociodemographic variables and psychosocial functioning across profiles to characterize the adult experiences of men in different maltreatment groups. The community sample consisted of 626 heterosexually active 21- to 30-year-old men. We identified four subgroups: Low Maltreatment (80% of the sample), Emotional and Physical Maltreatment (12%), Emotional and Sexual Maltreatment (4%), and Poly-Victimized (4%). The Low Maltreatment group had significantly lower IPV perpetration rates than the Emotional and Physical Maltreatment group, but groups did not significantly differ on peer violence or sexual assault perpetration rates. Overall, Poly-Victimized men were significantly worse off than the Low Maltreatment group regarding income, education level, and incarceration history. Their rates of recent anxiety and depression symptoms were also higher than those of Low Maltreatment men. Findings support the use of person-oriented techniques for deriving patterns of childhood maltreatment and how these patterns relate to psychological, behavioral, and social factors in adulthood.

Latent Classes of Maltreatment: A Systematic Review and Critique

This article reviews and critically evaluates available research on latent classes of maltreatment. Three major databases (PsycINFO, Web of Knowledge, and Academic Search Complete) were used to identify studies on latent classes of maltreatment published before June 1, 2016. Of 365 potentially relevant studies, 14 met inclusion criteria for review. Our analysis was guided by the following questions: (a) What observed indicators are being used to model classes of maltreatment? (b) What are the most commonly identified classes of maltreatment? and (c) What are the predictors and outcomes of classes of maltreatment? Across the studies, findings demonstrated how person-centered methods (i.e., latent class/profile analysis) may facilitate the study of maltreatment by concurrently addressing several methodological limitations common to the study of maltreatment, while also addressing heterogeneity in experiences of maltreatment. After providing an account of existing trends within the literature employing person-centered methodology in the study of maltreatment, we offer a critique of extant research, note recent methodological developments, and make numerous recommendations for future research using person-centered approaches to understanding maltreatment.

The divergent impact of catechol-O-methyltransferase (COMT) Val158Met genetic polymorphisms on executive function in adolescents with discrete patterns of childhood adversity

PURPOSE

Catechol-O-methyltransferase (COMT) Val¹⁵⁸Met functional polymorphisms play a crucial role in the development of executive function (EF), but their effect may be moderated by environmental factors such as childhood adversity. The present study aimed at testing the divergent impact of the COMT Val¹⁵⁸Met genotype on EF in non-clinical adolescents with discrete patterns of childhood adversity.

METHODS

A total of 341 participants completed the Childhood Trauma Questionnaire, the self-reported version of the Behavior Rating Inventory of Executive Function, and self-administered questionnaires on familial function. The participants' COMT Val¹⁵⁸Met genotype was determined. Associations among the variables were explored using latent class analysis and general linear models.

RESULTS

We found that Val/Val homozygotes showed significantly worse performance on behavioral shift, relative to Met allele carriers (F=5.921, p=0.015, Partial η²=0.018). Moreover, three typical patterns of childhood adversity, namely, low childhood adversity (23.5%), childhood neglect (59.8%), and high childhood adversity (16.7%), were found. Both childhood neglect and high childhood adversity had a negative impact on each aspect of EF and on global EF performance. Importantly, these results provided evidence for significant interaction effects, as adolescents with the Val/Val genotype showed inferior behavioral shift performance than Met carriers (F=6.647, p=0.010, Partial η²=0.020) in the presence of high childhood adversity. Furthermore, there were no differences between the genotypes for childhood neglect and low childhood adversity.

CONCLUSIONS

Overall, this is the first study to show that an interaction between the COMT genotype and childhood adversity affects EF in non-clinical adolescents. These results suggest that the COMT genotype may operate as a susceptibility gene vulnerable to an adverse environment.

Relation between lifespan polytrauma typologies and post-trauma mental health

BACKGROUND

Most individuals experience more than one trauma. Hence, it is important to consider the count and types of traumas (polytraumatization) in relation to post-trauma mental health.

METHOD

The current study examined the relation of polytraumatization patterns to PTSD clusters (intrusions, avoidance, negative alterations in cognitions and mood [NACM], and alterations in arousal and reactivity [AAR]), depression, and impulsivity facets (lack of perseverance, lack of premeditation, negative urgency, sensation seeking) using a web-based sample of 346 participants. Age, gender, race, and ethnicity were covariates.

RESULTS

Results of latent class analyses indicated a three-class solution: Low Experience, Moderate Experience - Predominent Threat/Indirect PTEs (Moderate Experience), and High Experience - Predominant Interpersonal PTEs (High/Interpersonal). Multinomial logistic regression results indicated that ethnicity and gender were significant covariates in predicting Low versus High/Interpersonal Class, and Moderate Experience versus High/Interpersonal Class membership, respectively. The High/Interpersonal Class had higher scores on most PTSD clusters, depression, and the impulsivity facets of lack of perseverance and negative urgency compared to the other classes. The Low and Moderate Experience Classes differed on PTSD's avoidance and AAR clusters (lower in the former).

CONCLUSIONS

Individuals exposed to multiple PTE types, particularly interpersonal traumas, may be at risk for more severe post-trauma symptoms.

Childhood Maltreatment and BMI Trajectory: The Mediating Role of Depression

INTRODUCTION

Childhood maltreatment is associated with later obesity, but the underlying mechanisms are unknown. The objective of this study was to estimate the extent to which depression mediates the associations between childhood maltreatment and BMI in adolescence through adulthood.

METHODS

Data on a cohort of 13,362 adolescents in the National Longitudinal Study of Adolescent to Adult Health (Wave I [1994-1995] to Wave IV [2008-2009]) were analyzed in 2015-2016. Classes of maltreatment experienced prior to age 12 years were statistically identified using latent class analysis. Gender-stratified latent growth curve analysis was used to estimate total effects of maltreatment classes on latent BMI trajectory (aged 13-31 years) and indirect effects of maltreatment classes that occurred through latent depression trajectory (aged 12-31 years).

RESULTS

Four latent maltreatment classes were identified: high abuse and neglect; physical abuse dominant; supervisory neglect dominant; and no/low maltreatment. In girls, compared with no/low maltreatment, supervisory neglect dominant (coefficient=0.3, 95% CI=0.0, 0.7) and physical abuse dominant (coefficient=0.6, 95% CI=0.1, 1.2) maltreatment were associated with faster gain in BMI. Change in depression over time fully mediated the association of BMI slope with physical abuse dominant maltreatment, but not with supervisory neglect dominant maltreatment. In boys, high abuse and neglect maltreatment was associated with marginally greater BMI at baseline (coefficient=0.7, 95% CI= -0.1, 1.5); this association was not mediated by depression.

CONCLUSIONS

Although maltreatment was associated with depression and BMI trajectories from adolescence to adulthood, depression only mediated associations with physical abuse dominant maltreatment in girls.
