Childhood maltreatment is associated with a sex‐dependent functional reorganization of a brain inhibitory control network

Childhood adversity represents a major risk factor for drug addiction and other mental disorders. However, the specific mechanisms by which childhood adversity impacts human brain organization to confer greater vulnerability for negative outcomes in adulthood is largely unknown. As an impaired process in drug addiction, inhibitory control of behavior was investigated as a target of childhood maltreatment (abuse and neglect). Forty adults without Axis‐I psychiatric disorders (21 females) completed a Childhood Trauma Questionnaire (CTQ) and underwent functional MRI (fMRI) while performing a stop‐signal task. A group independent component analysis identified a putative brain inhibitory control network. Graph theoretical analyses and structural equation modeling investigated the impact of childhood maltreatment on the functional organization of this neural processing network. Graph theory outcomes revealed sex differences in the relationship between network functional connectivity and inhibitory control which were dependent on the severity of childhood maltreatment exposure. A network effective connectivity analysis indicated that a maltreatment dose‐related negative modulation of dorsal anterior cingulate (dACC) activity by the left inferior frontal cortex (IFC) predicted better response inhibition and lesser attention deficit hyperactivity disorder (ADHD) symptoms in females, but poorer response inhibition and greater ADHD symptoms in males. Less inhibition of the right IFC by dACC in males with higher CTQ scores improved inhibitory control ability. The childhood maltreatment‐related reorganization of a brain inhibitory control network provides sex‐dependent mechanisms by which childhood adversity may confer greater risk for drug use and related disorders and by which adaptive brain responses protect individuals from this risk factor.

Is there a complex relation between social anxiety disorder,childhood traumatic experiences and dissociation?

Background: A possible relationship has been suggested between social anxiety and dissociation. Traumatic experiences, especially childhood abuse, play an important role in the aetiology of dissociation.

Aim: This study assesses childhood trauma history, dissociative symptoms, and dissociative disorder comorbidity in patients with social anxiety disorder (SAD).

Method: The 94 psychotropic drug-naive patients participating in the study had to meet DSM-IV criteria for SAD. Participants were assessed using the Structured Clinical Interview for DSM-IV Dissociative Disorders (SCID-D), the Dissociation Questionnaire (DIS-Q), the Liebowitz Social Anxiety Scale (LSAS), and the Childhood Trauma Questionnaire (CTQ). Patients were divided into two groups using the DIS-Q, and the two groups were compared.

Results: The evaluation found evidence of at least one dissociative disorder in 31.91% of participating patients. The most prevalent disorders were dissociative disorder not otherwise specified (DDNOS), dissociative amnesia, and depersonalization disorders. Average scores on LSAS and fear and avoidance sub-scale averages were significantly higher among the high DIS-Q group (p?p?Conclusions: It is concluded that, on detecting SAD symptoms during hospitalization, the clinician should not neglect underlying dissociative processes and traumatic experiences among these patients.     

The protective role of friendship on the effects of childhood abuse and depression

Background: This study explored the relationships between childhood maltreatment (sexual, physical, and emotional abuse, as well as neglect), adult depression, and perceived social support from family and friends. Methods: As part of an NIH‐funded study of risk and resilience at a public urban hospital in Atlanta, 378 men and women recruited from the primary care and obstetrics gynecology clinic waiting areas answered questions about developmental history, traumatic experiences, current relationship support, and depressive symptoms. Results: Childhood emotional abuse and neglect proved more predictive of adult depression than childhood sexual or physical abuse. In females only, perceived friend social support protected against adult depression even after accounting for the contributions of both emotional abuse and neglect. Conclusions: These findings may elucidate the particular importance of understanding the effects that emotional abuse and neglect have on adult depression, and how perceived friendship support may provide a buffer for women with a history of early life stress who are at risk to develop adult depression.

Psychometric functioning,socio‐demographic variability of childhood maltreatment in the general population and its effects of depression

Maltreatment of children is a major public‐health and social‐welfare problem but socio‐demographic variability has received little attention. This work addresses such variability in a general population cohort and associations with depression. Analyses were based on the cross‐sectional SHIP‐LEGEND examination among 2265 adults (29–89 years). Childhood maltreatment was multi‐dimensionally assessed with the German 28‐item Childhood Trauma Questionnaire (CTQ): emotional neglect; emotional abuse; physical neglect; physical abuse; sexual abuse. Non‐linear associations between CTQ responses and age were assessed with fractional polynomials and cubic splines. Scale properties were analysed with confirmatory factor analyses and item response models. Associations between childhood maltreatment domains and depression [Beck Depression Inventory‐II (BDI‐II)] were assessed. The majority (58.9%) reported events indicative of at least mild levels of childhood maltreatment. CTQ subscales showed characteristically different non‐linear associations to age across the five studied domains, indicating methodological issues like recall bias and the influence of seminal events. Psychometric scale properties were acceptable to good for all subscales except for physical neglect. Associations to depression measures varied systematically across socio‐demographic strata. We conclude that socio‐demographic variability is a major issue when studying self‐reported childhood maltreatment in a community sample. This needs to be taken into account for the study of associations to psychiatric key outcomes. Copyright © 2014 John Wiley & Sons, Ltd.     

Childhood trauma and current psychological functioning in adults with social anxiety disorder

Etiological models of social anxiety disorder (SAD) suggest that early childhood trauma contributes to the development of this disorder. However, surprisingly little is known about the link between different forms of childhood trauma and adult clinical symptoms in SAD. This study (1) compared levels of childhood trauma in adults with generalized SAD versus healthy controls (HCs), and (2) examined the relationship between specific types of childhood trauma and adult clinical symptoms in SAD. Participants were 102 individuals with generalized SAD and 30 HCs who completed measures of childhood trauma, social anxiety, trait anxiety, depression, and self-esteem. Compared to HCs, individuals with SAD reported greater childhood emotional abuse and emotional neglect. Within the SAD group, childhood emotional abuse and neglect, but not sexual abuse, physical abuse, or physical neglect, were associated with the severity of social anxiety, trait anxiety, depression, and self-esteem.     

Association between childhood maltreatment and social functioning in individuals with affective disorders: A systematic review and meta-analysis

Objective

Childhood maltreatment has been linked to impairments in social functioning and social cognition in adults with affective disorders. However, conclusions have been limited by inconsistent findings across different maltreatment subtypes and social domains. We conducted a systematic review and meta-analysis to quantify associations between childhood maltreatment (overall and subtypes - physical, emotional and/or sexual abuse, and/or physical and/or emotional neglect) and different domains of social functioning and social cognition in adults with affective disorders (bipolar disorder or major depressive disorder). We also examined effect moderators and mediators of these associations.

Methods

A systematic search was performed on 12.12.2022 which identified 29 studies included in qualitative synthesis (n = 3022 individuals with affective disorders), of which 27 (n = 2957) were pooled in meta-analyses. Across studies, five social functioning and five social cognition domains were examined, of which four domains of social functioning and two domains of social cognition had sufficient data for meta-analysis (PROSPERO CRD42022288976).

Results

Social functioning: childhood maltreatment was associated with lower global social functioning (r = −0.11 to −0.20), poorer interpersonal relations (r = −0.18 to −0.33), and with aggressive behaviour (r = 0.20–0.29) but was unrelated to vocational functioning. Emotional abuse and emotional neglect showed the largest magnitudes of effect. Social cognition: there was no meta-analytic evidence of associations between maltreatment and social cognition domains. Exploratory moderation analyses did not identify any consistent moderators. Narrative synthesis identified attachment style as possible moderator, and sensory patterns, anxiety, and depressive symptoms as possible mediators between childhood maltreatment and social outcomes. Overall, the available evidence was limited, particularly in relation to social cognition.

Conclusions

Adults with affective disorders are at risk of social functioning difficulties after childhood maltreatment exposure, an effect observed across multiple maltreatment subtypes, social functioning domains, and diagnoses. Addressing social functioning problems may benefit maltreated adults with both bipolar disorder and major depressive disorder.     

Childhood maltreatment is associated with depression but not with hypochondriasis in later life

Objective

Previous studies demonstrated that a history of childhood trauma is linked to mental disorders in adulthood, particularly to depression. Adverse childhood experiences are also considered to contribute to the risk of hypochondriasis, but the results of previous studies have not been conclusive with respect to the strength and specificity of this association. Therefore, we compared the association of adverse childhood experiences with both hypochondriasis and depression.

Methods

Fifty-eight patients with hypochondriasis, 52 patients with depression, and 52 healthy control participants completed the Childhood Trauma Questionnaire (CTQ) which assesses 5 varieties of abuse and neglect. A clinical interview (SCID-I) was used to establish DSM-IV diagnoses. Associations between childhood maltreatment, hypochondriasis and depression were estimated by means of analyses of variance and multiple linear regression analyses.

Results

In comparison to hypochondriacal and healthy participants, patients with a current depressive disorder reported more emotional abuse as well as more emotional and physical neglect during childhood. Patients with hypochondriasis reported more emotional neglect than healthy individuals. However, when predicting the CTQ trauma types by diagnostic category adjusting for sex and comorbid DSM-IV diagnoses, emotional abuse, emotional neglect, physical abuse, physical neglect, as well as the CTQ total score were significantly associated with depression, but none of the CTQ scores was significantly related to hypochondriasis.

Conclusions

The findings suggest a robust association of childhood maltreatment with depression but not with hypochondriasis. This result does not support etiological models of hypochondriasis which rely on childhood maltreatment as a risk factor for the development of this disorder.     

Sex differences in the effect of childhood trauma on the clinical expression of early psychosis

Childhood trauma, a risk factor of psychosis, is associated the clinical expression of the illness (greater severity of psychotic symptoms; poorer cognitive performance). We aimed to explore whether there are sex differences in this relationship. We studied 79 individuals with a psychotic disorder (PD) with < 3 years of illness and 59 healthy subjects (HS). All participants were administered the MATRICS Cognitive Consensus Cognitive Battery (MCCB) to assess cognition. Depressive, positive and negative psychotic symptoms, and global functioning were also assessed. History of childhood trauma was assessed using the Childhood Trauma Questionnaire (CTQ). Patients reported a greater history of childhood trauma on all CTQ domains (emotional, physical and sexual abuse, and physical and emotional neglect). A poorer cognitive performance was also observed in PD when compared to HS. No sex differences were found in the CTQ scores. In the relationship between childhood trauma and psychopathological symptoms, significant correlations were found between CTQ scores and positive and negative psychotic symptoms, depressive symptoms and poorer functionality, but only in women. Childhood trauma was associated with poorer social cognition in both men and women. Of all CTQ dimensions, emotional neglect and physical neglect were more clearly associated with a more severe psychopathological and cognitive profile. Our results suggest that childhood trauma, particularly emotional and physical neglect, is associated with the clinical expression of psychosis and that there are sex differences in this relationship.     

儿童期虐待对新兵社会支持及应对方式的影响

目的研究儿童期虐待对新兵社会支持及应对方式的影响。方法对505名入伍新兵进行儿童受虐问卷（CTQ-SF）、简易应对方式问卷（SCSQ）、青少年社会支持量表评定。结果遭受儿童期虐待的新兵在应付方式选择及社会支持上显著低于无虐待组（P〈0．05）。简单相关分析显示儿童期情感虐待、情感忽视、躯体忽视及总虐待分均与积极应对呈负相关（P〈0．01）;儿童期经历过情感虐待、情感忽视、性虐待、躯体虐待、躯体忽视及虐待总分均与消极应对呈正相关（P〈0．05,P〈0．01）。儿童期情感虐待、躯体虐待、情感忽视、躯体忽视及总虐待分均与社会支持总分、客观支持、支持利用度呈负相关（P〈0．01）;儿童期经历过情感虐待、情感忽视、性虐待、躯体虐待、躯体忽视及虐待总分均与主观支持成负相关（P〈0．05,P〈0．01）。情感忽视、躯体忽视与积极应对方式呈负相关（P=0．000,P=0．003）;虐待总分、情感虐待与消极应对方式呈正相关（P=0．032,P=0．026）,与社会支持总分呈负相关（P=0．000,P=0．011）。结论儿童期遭受虐待的新兵在应对方式上往往采取消极应对,且社会支持不良。     

Relationship between orexin A and childhood maltreatment in female patients with depression and anxiety

Objective: Childhood maltreatment leads to neuroendocrine changes, which may be associated with an increased vulnerability for psychopathology, such as depression and anxiety in later life. This study aimed to investigate the relationship between childhood maltreatment and orexin A levels in patients with depression and anxiety. The study consisted of 27 female outpatients who presented with depressive and/or anxiety symptoms, and 27 healthy female controls. Childhood trauma history was assessed using the childhood trauma questionnaire (CTQ-28) in patients and controls. Serum levels of orexin and cortisol were measured in all subjects. There were positive correlations between serum orexin levels and CTQ total score and between orexin levels and some CTQ subscale scores, such as physical and emotional neglect, in patients. Orexin levels in patients with a positive history of physical and emotional neglect were higher than those in patients with a negative history of them. In the controls, there was a positive correlation between emotional neglect score and serum orexin level. There were no differences in serum levels of orexin and cortisol between patients and controls. Orexin levels may be associated with childhood maltreatment per se, rather than psychopathology, such as depression or anxiety.     

Childhood maltreatment and personality disorders in adult patients with binge eating disorder

OBJECTIVE: To examine the association between retrospective reports of different types of childhood maltreatment and current personality disorders (PDs) in patients with binge eating disorder (BED). METHOD: A total of 116 consecutive out-patients with DSM-IV BED were assessed with diagnostic interviews and completed the Childhood Trauma Questionnaire to assess childhood maltreatment in five domains (emotional abuse, physical abuse, sexual abuse, emotional neglect and physical neglect). RESULTS: Eighty-two percent of patients reported some form of childhood maltreatment and 30% met criteria for at least one PD. Emotional abuse was significantly associated with cluster C PD overall and specifically with avoidant PD. CONCLUSION: Reports of emotional abuse - but not other forms of maltreatment - were associated with greater likelihood of a PDs in patients with BED.     

The effect of Avoidant Personality Disorder on the persistence of Generalized Social Anxiety Disorder in the general population: results from a longitudinal, nationally representative mental health survey

Background: The primary objective of this study was to prospectively examine the role of Avoidant Personality Disorder (AvPD) as a determinant in the outcome of Generalized Social Anxiety Disorder (GSAD) using Wave 2 of the National Epidemiologic Survey of Alcohol and Related Conditions 3 years later. Method: This study analyzed data from Waves 1 and 2 of the NESARC (n = 34,653). GSAD was operationalized based on the DSM‐IV definitions of this SAD subtype. Results: Logistic regression analyses indicated that AvPD significantly predicted the persistence of GSAD, even after adjusting for a number of important sociodemographic variables and other psychiatric comorbidity. AvPD did not significantly predict outcome in non‐generalized SAD. Conclusions: AvPD can influence the course of GSAD in adulthood. Specific personality dimensions may underlie and explain the similarities between AvPD and GSAD. Self‐criticism could be a shared feature of both AvPD and GSAD and could represent an important psychological marker of poor prognosis in comorbid GSAD and AvPD.

Childhood abuse is associated with increased startle reactivity in adulthood

Background: Understanding the neurobiological correlates of childhood maltreatment is critical to delineating stress‐related psychopathology. The acoustic startle response (ASR) is a subcortical reflex modulated by neural systems implicated in posttraumatic stress disorder (PTSD). The ASR is conserved across species and is increased in rodent models of developmental stress. Methods: We measured ASR to a 40 ms noise probe as well as fear‐potentiated startle using electromyographic recordings of the eyeblink in a primarily African American sample (N=60) from a highly traumatized civilian population. We assessed self‐reported history of abuse with the Childhood Trauma Questionnaire and current symptoms with the PTSD Symptom Scale and the Beck Depression Inventory. Results: We found that subjects reporting a history of high levels of physical or sexual abuse had increased startle on all trial types relative to those with low abuse (P<.01). This effect remained significant after co‐varying for the subjects' age and sex, as well as PTSD and depression symptoms. Perceived childhood sexual abuse was the greatest predictor of increased startle response. Notably, emotional abuse in childhood did not affect baseline startle, and all groups demonstrated equivalent levels of fear‐potentiated startle. Conclusions: The long‐lasting effects of early life trauma result in increased risk for adult psychopathology. These new data demonstrate that a self‐report history of child abuse is related to altered baseline startle response that is not accounted for by PTSD or depression symptoms. Increased startle may be a biomarker of stress responsiveness that can be a persevering consequence of early trauma exposure during childhood. Depression and Anxiety 26:1018–1026, 2009.

Childhood maltreatment and adult mental health

Background: The relationship between reported childhood maltreatment and general psychological and post-traumatic distress was examined in a sample of 551 adults from different risk samples. Aims: Exposure to childhood maltreatment was assessed using the Childhood Trauma Questionnaire Short Form, which detects physical, emotional and sexual abuse and past physical and emotional neglect. Methods: The participants’ current levels of post-traumatic stress symptoms and general psychological stress symptoms were measured with the Impact of Event Scale – Revised and the Symptom Checklist 90 – Revised, respectively. Results: The results reveal a high prevalence of reported childhood maltreatment in both men and women, and the severity levels of the five types of childhood maltreatment showed significant associations with the extent of current post-traumatic and general psychological distress. Conclusion: The findings emphasize the need for appropriate procedures for identifying childhood maltreatment.     

Abuse and neglect in adolescents of Jammu,India: The role of gender,family structure,and parental education

The present study aimed to assess the factor structure of the childhood trauma questionnaire (CTQ; Bernstein & Fink, 1998), and use it to describe the prevalence of abuse and neglect in Indian adolescents, and its associations with gender, family structure (nuclear vs. joint), and level of parental education. Participants were 702 adolescents from Jammu in the age range of 13–17 years (41.5% female). We found acceptance for a four-factor intercorrelated model for the CTQ with emotional abuse, physical abuse, sexual abuse, and neglect (5 emotional neglect and 2 physical neglect items) factors following a confirmatory factor analysis (CFA). Forty-one to sixty-one percent of adolescents reported maltreatment which is higher in comparison with CTQ based studies from the West. Analysis of CFA with covariates (MIMIC model) indicated that males, and adolescents of less educated mothers’ and from joint families reported higher abuse and neglect, and sexual abuse, respectively, while fathers’ education level was not associated with abuse or neglect. Implications of these findings are highlighted.     

Childhood traumas in euthymic bipolar disorder patients in Eastern Turkey and its relations with suicide risk and aggression

Abstract

Purpose: The aim of this study was to determine the relationship between childhood trauma and aggression-suicidal behavior in patients with bipolar disorder.

Material and Methods: A total of 112 outpatients diagnosed with bipolar disorder in remission in the province of Siirt on the east coast of Turkey were included in this study carried out between January and June 2018. Personal Information Form, Childhood Trauma Questionnaire (CTQ), Buss–Perry Aggression Scale (BPAS) and Suicide Probability Scale (SPS) were used for data acquisition.

Results: It was determined that patients with bipolar disorder have 89.3% of physical neglect, 74.1% of emotional neglect, 75.9% of physical abuse, 79.5% of emotional abuse and 40.2% of sexual abuse. The mean score of CTQ was 66.8?±?19.2, the total score of BPAS was 94.6?±?28.8 and the total score of SPS was 85.3?±?17.9. A statistically significant and positive correlation was determined between CTQ, BPAS and SPS (p?<?0.05).

There was a weak and positive relationship between BPAS, CTQ (r?=?0.325**; p?<?0.05) and subscales of CTQ which are emotional abuse (r?=?0.350**; p?<?0.05), physical abuse (r?=?0.354**; p?<?0.01), physical neglect (r?=?0.313**; p?<?0.01) and emotional neglect (r?=?0.316**; p?<?0.01). A statistically significant difference was observed between the regular use of drugs, violence against others and total score of CTQ, BPAS and SPS (p?<?0.05).

Conclusion: It is suggested that patients diagnosed with bipolar disorder should be evaluated with regards to childhood trauma history by taking into consideration sociodemographic characteristics and psychiatric support in order to prevent their aggression and suicide attempts.     

Role of childhood traumatic experience in personality disorders in China

BackgroundThere has been no large-scale examination of the association between types of childhood abuse and personality disorders (PDs) in China using standardized assessment tools and the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria. Hence, this study aimed to explore the relationship between retrospective reports of various types of childhood maltreatments and current DSM-IV PDs in a clinical population in China, Shanghai.MethodOne thousand four hundred two subjects were randomly sampled from the Shanghai Psychological Counselling Centre. PDs were assessed using the Personality Diagnostic Questionnaire, Fourth Edition Plus. Participants were also interviewed using the Structured Clinical Interview for DSM-IV axis II. The Child Trauma Questionnaire (CTQ) was used to assess childhood maltreatment in 5 domains (emotional abuse, physical abuse, sexual abuse, emotional neglect, and physical neglect).ResultsAccording to Pearson correlations, childhood maltreatment had a strong association with most PDs. Subsequently, using partial correlations, significant relationships were also demonstrated between cluster B PDs and all the traumatic factors except physical neglect. A strongest positive correlation was found between cluster B PD and CTQ total scores (r = .312, P < .01). Using the Kruskal-Wallis rank sum test, significant differences in 4 groups of subjects (clusters A, B, and C PD and non-PD) in terms of emotional abuse (χ² = 34.864, P < .01), physical abuse (χ² = 14.996, P < .05), sex abuse (χ² = 9.211, P < .05), and emotional neglect (χ² = 17.987, P < .01) were found. Stepwise regression analysis indicated that emotional abuse and emotional neglect were predictive for clusters A and B PD, and sexual abuse was highly predictive for cluster B PD; only emotional neglect was predictive for cluster C PD.ConclusionEarly traumatic experiences are strongly related to the development of PDs. The effects of childhood maltreatment in the 3 clusters of PDs are different. Childhood trauma has the most significant impact on cluster B PD.     

Relationship of childhood maltreatment to the onset and course of major depression in adulthood.

The objective of this research was to determine the prevalence of retrospectively recalled childhood trauma among depressed patients and to examine the relationship between retrospective recall of childhood maltreatment and the onset, course, and severity of major depression in adulthood. Forty-seven adults with DSM-IV major depression and forty-one healthy comparison subjects were administered the Childhood Trauma Questionnaire (CTQ), a self-report measure of traumatic experiences in childhood. Age at onset of first depressive episode, number of lifetime depressive episodes, current depressive severity, and presence of lifetime anxiety and substance use comorbidity were determined for the depressed patients using the Structured Clinical Interview for DSM-IV. Patients with major depression recalled significantly more severe emotional abuse, emotional neglect, and physical abuse than the healthy comparison subjects. Among the depressed subjects, the severity of childhood trauma (most notably emotional abuse) predicted 25-28% of the variance in age at onset of first depressive episode (earlier onset) and number of lifetime depressive episodes (more episodes). Depressed patients with recall of childhood trauma also experienced a significantly greater number of comorbid mental disorders (2.9 vs. 1.9) than depressed patients without trauma histories. The findings must be tempered by the possibility of a recall bias toward more adverse childhood experiences in the depressed patients. To the extent that these data are valid, they suggest that childhood maltreatment may influence the onset, course, and comorbid character of major depression.     

Childhood maltreatment is associated with an automatic negative emotion processing bias in the amygdala

Major depression has been repeatedly associated with amygdala hyper‐responsiveness to negative (but not positive) facial expressions at early, automatic stages of emotion processing using subliminally presented stimuli. However, it is not clear whether this “limbic bias” is a correlate of depression or represents a vulnerability marker preceding the onset of the disease. Because childhood maltreatment is a potent risk factor for the development of major depression in later life, we explored whether childhood maltreatment is associated with amygdalar emotion processing bias in maltreated but healthy subjects. Amygdala responsiveness to subliminally presented sad and happy faces was measured by means of fMRI at 3 T in N = 150 healthy subjects carefully screened for psychiatric disorders. Childhood maltreatment was assessed by the 25‐item childhood trauma questionnaire (CTQ). A strong association of CTQ‐scores with amygdala responsiveness to sad, but not happy facial expressions emerged. This result was further qualified by an interaction of emotional valence and CTQ‐scores and was not confounded by trait anxiety, current depression level, age, gender, intelligence, education level, and more recent stressful life‐events. Childhood maltreatment is apparently associated with detectable changes in amygdala function during early stages of emotion processing which resemble findings described in major depression. Limbic hyper‐responsiveness to negative facial cues could be a consequence of the experience of maltreatment during childhood increasing the risk of depression in later life. Limitation: the present association of limbic bias and maltreatment was demonstrated in the absence of psychopathological abnormalities, thereby limiting strong conclusions.

Validation of the French version of the CTQ and prevalence of the history of maltreatment

This study demonstrates that the five maltreatment scales in the long and short versions of the CTQ are valid and usable with French-speaking populations. It also shows emotional neglect to be the most common form of maltreatment in its general population sample, and physical neglect to be the least common. Physical, emotional and sexual abuse prevalences in the convenience sample roughly correspond to the rates generally obtained in non-clinical samples. Finally, women in the sample display greater co-occurrence of different forms of maltreatment, especially involving sexual abuse, than men.
