Differential constellations of dissociative symptoms and their association with childhood trauma – a latent profile analysis

ABSTRACT Background: While several studies documented a positive correlation between childhood maltreatment severity and dissociation severity, it is currently unknown whether specific dissociative symptoms cluster together among individuals with childhood trauma histories ranging from none to severe. Objective: We aimed to explore symptom constellations across the whole spectrum of dissociative processing from patients with severe dissociative disorders to healthy controls and relate these to maltreatment severity and sociodemographic characteristics. Methods: We employed latent profile analysis to explore symptom profiles based on five subscales, measuring absorption, depersonalization, derealization, somatoform and identity alteration, based on the 20 items of the German short version of the Dissociative Experiences Scale-II (Fragebogen zu Dissoziativen Symptomen-20) in a large aggregate sample (n = 3,128) overrepresenting patients with trauma-related disorders. We then related these profiles to maltreatment severity as measured by the five subscales of the Childhood Trauma Questionnaire as well as sociodemographic characteristics. Results: Based on the five FDS subscales, six clusters differentiated by symptom severity, but not symptom constellations, were identified. Somatoform dissociation varied in accordance with the remaining symptom clusters. The cluster with the highest overall symptom severity entailed nearly all subjects diagnosed with Dissociative Identity Disorder and was characterized by extreme levels of childhood maltreatment. Both abuse and neglect were predictive of cluster membership throughout. Conclusions: The higher the severity of dissociative processing in a cluster, the more subjects reported high severity and multiplicity of childhood maltreatment. However, some subjects remain resilient to the development of dissociative processing although they experience extreme childhood maltreatment.

Pathway from Childhood Maltreatment to Perceived Parental Competence and Intimate Partner Violence Among Expecting Fathers: The Role of PTSD Symptoms

ABSTRACT Men who have a history of childhood maltreatment may be at risk of experiencing significant challenges during the transition to parenthood, which might be explained by the presence of post-traumatic stress disorder (PTSD) symptoms. Using a nonclinical community sample of 230 expecting fathers, the aims of the current study were as follows (1) to investigate, during the prenatal period, associations between childhood maltreatment and perceived parental competence as well as between childhood maltreatment and intimate partner violence, and (2) to evaluate whether PTSD symptoms contributed to explaining these associations. A structural equation model showed that the severity of childhood maltreatment predicted more severe PTSD symptoms, which in turn predicted higher levels of intimate partner violence as well as a lower perceived parental competence. No direct associations between childhood maltreatment and both perceived parental competence and intimate partner violence were observed. Implications for interventions and future research are discussed.

Childhood maltreatment and mentalizing capacity: A meta-analysis

BackgroundThe protective role of mentalizing capacity against the adverse effects of childhood maltreatment (CM) is acknowledged; however, empirical studies have yielded diverse conclusions regarding the relationship between childhood maltreatment and mentalizing capacity. ObjectiveThis meta-analytic review aims to comprehensively summarize and quantify the association between childhood maltreatment and mentalizing capacity. Participants and settingA total of 23 studies involving 3910 participants were included in the analysis. MethodsSystematic searches across eight bibliographic databases identified peer-reviewed publications describing empirical studies on the interplay between CM and mentalizing capacity. Effect sizes (r) were synthesized using random-effects models. A moderated effects analysis was conducted on five variables: participant gender, age group, mental health status, mentalizing capacity measurement, and childhood maltreatment measurement. ResultsThe findings showed a significant moderate negative correlation between childhood maltreatment and mentalizing capacity (r = −0.21, 95 % CI = [−0.26, −0.15]). This suggests that heightened severity of childhood maltreatment corresponds to lower mentalizing capacity. Moreover, the strength of this correlation was influenced by participant gender, age group, mental health status, mentalizing capacity measurement, and CM measurement. ConclusionsThe controversy surrounding the link between CM and mentalizing capacity gains clarity when considering significant moderating variables. The pooled effect provides a preliminary definition of the magnitude and direction of this correlation.

Stress and emotion recognition predict the relationship between a history of maltreatment and sensitive parenting behaviors: A moderated-moderation.

Our study proposes to examine how stress and emotion recognition interact with a history of maltreatment to influence sensitive parenting behaviors. A sample of 58 mothers and their children aged between 2 and 5 years old were recruited. Parents' history of maltreatment was measured using the Child Trauma Questionnaire. An emotion recognition task was performed. Mothers identified the dominant emotion in morphed facial emotion expressions in children. Mothers and children interacted for 15 minutes. Salivary cortisol levels of mothers were collected before and after the interaction. Maternal sensitive behaviors were coded during the interaction using the Coding Interactive Behavior scheme. Results indicate that the severity of childhood maltreatment is related to less sensitive behaviors for mothers with average to good abilities in emotion recognition and lower to average increases in cortisol levels following an interaction with their children. For mothers with higher cortisol levels, there is no association between a history of maltreatment and sensitive behaviors, indicating that higher stress reactivity could act as a protective factor. Our study highlights the complex interaction between individual characteristics and environmental factors when it comes to parenting. These results argue for targeted interventions that address personal trauma.

The Role of Emotional Processes in Explaining the Link Between Severity of Childhood Maltreatment and Relationship Difficulties.

Up to 32% of adults have experienced some form of childhood maltreatment (CM). Research has shown that these early childhood experiences are associated with a variety of interpersonal difficulties in adult sexual and romantic relationships. Polusny and Follette have suggested that these negative long-term effects are the result of emotional avoidance strategies that individuals use to cope with thoughts, feelings, and memories associated with CM. The present study tested this theorized mediational model with a sample of 150 participants, all of whom were currently in long-term relationships. Participants completed questionnaires designed to assess the severity of CM, fear of their own emotions, and a task designed to assess their accuracy at identifying emotions. Additionally, participants completed a variety of measures assessing the quality of their sexual and romantic relationships. These measures assessed their satisfaction, their communication, and the extent of problems in each domain. Our results showed that higher levels of CM were associated with lower satisfaction with communication and more problems in both the romantic and sexual domains. In regard to our mediational hypothesis, we found partial support showing that fear of one's own emotions and emotion recognition mediated some of these associations. Our findings suggest that treatments targeting affective processes may be particularly important for helping victims of CM.

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 mediation effect of glucocorticoid receptor gene (NR3C1) methylation between childhood maltreatment and depressive symptoms in Chinese adolescents: A 2-year longitudinal study.

This three-wave longitudinal study examined whether methylation alterations in promoter exon 1F of a stress-related gene-NR3C1 (NR3C1-1F)-explained the longitudinal associations between childhood maltreatment and adolescent depressive symptoms. A total of 370 Han Chinese adolescents (Mage = 16.31 ± 1.28 years; 51.4% girls) recruited from Shandong, China were tracked from 2018 to 2020. The results showed that the severity of childhood maltreatment, especially that of emotional abuse and physical neglect, conferred risk for adolescent depressive symptoms via reducing NR3C1-1F methylation levels. These mediation effects of NR3C1-1F methylation did not vary between adolescent sex or NR3C1 BclI and Tth111I polymorphisms. The findings highlight how childhood maltreatment contributes to psychopathology development at a biological level.

Increased immunological markers in female adolescents with non-suicidal self-injury

BackgroundNonsuicidal self-injury (NSSI) is a prevalent health problem among adolescents and commonly associated with psychological stressors such as childhood maltreatment and comorbid psychiatric disorders (e.g., depression). There is evidence that alterations of immunological markers may occur in the context of both environmental stress and psychopathological development. MethodHere, we investigated differences in plasma/serum leukocytes, cortisol, c-reactive protein and interleukin-6 in a large sample of female adolescents with NSSI (n = 155) and healthy controls (HC, n = 42). Further, we assessed correlations between inflammatory markers, depression severity and the severity of childhood maltreatment. ResultsThe absolute number of leukocytes and the leukocyte/cortisol ratio (adjusted for body mass index and smoking) were significantly higher in NSSI as compared to HC, whereas interleukin-6 and CRP levels did not differ significantly between groups. Childhood maltreatment scores were significantly correlated with the leukocyte/cortisol ratio and depression severity was significantly correlated with both, absolute leukocyte numbers and the leukocyte/cortisol ratio. ConclusionsOur results suggest that an immune activation can be detected in female adolescents with NSSI. Depression and childhood maltreatment, which are commonly reported in NSSI, may potentially underlie immune activation and partially explain group differences.

Aberrant brain connectivity is associated with childhood maltreatment in individuals with major depressive disorder.

Although childhood maltreatment confers a high risk for the development of major depressive disorder, the neurobiological mechanisms underlying this connection remain unknown. The present study sought to identify the specific resting-state networks associated with childhood maltreatment. We recruited major depressive disorder patients with and without a history of childhood maltreatment (n = 31 and n = 30, respectively) and healthy subjects (n = 80). We used independent component analysis to compute inter- and intra- network connectivity. We found that individuals with major depressive disorder and childhood maltreatment could be characterized by the following network disconnectivity model relative to healthy subjects: (i) decreased intra-network connectivity in the left frontoparietal network and increased intra-network connectivity in the right frontoparietal network, (ii) decreased inter-network connectivity in the posterior default mode network-auditory network, posterior default mode network-limbic system, posterior default mode network-anterior default mode network, auditory network-medial visual network, lateral visual network - medial visual network, medial visual network-sensorimotor network, medial visual network - anterior default mode network, occipital pole visual network-dorsal attention network, and posterior default mode network-anterior default mode network, and (iii) increased inter-network connectivity in the sensorimotor network-ventral attention network, and dorsal attention network-ventral attention network. Moreover, we found significant correlations between the severity of childhood maltreatment and the intra-network connectivity of the frontoparietal network. Our study demonstrated that childhood maltreatment is integrally associated with aberrant network architecture in patients with major depressive disorder.

Sexual, Physical, and Emotional Maltreatment in Childhood Are Differentially Associated With Sexual and Physical Revictimization in Adulthood.

Childhood maltreatment increases risk for sexual and physical revictimization in adulthood. The goal of the current study was to examine whether this risk is associated with specific maltreatment types (i.e., sexual vs. physical vs. emotional maltreatment vs. neglect) and perpetrators (i.e., mother vs. father). Participants included 720 adult women from North America and the United Kingdom, recruited through the online platform Prolific Academic. The severity of childhood maltreatment and adult physical and sexual victimization were assessed in two separate sessions through self-report questionnaires. All maltreatment types were modeled together to account for their co-occurrence. Greater severity of sexual maltreatment was significantly and independently associated with greater risk for sexual, physical, and sexual + physical revictimization. Further, in the full sample, risk of revictimization was predicted by greater severity of father-perpetrated emotional and physical maltreatment. In contrast, in subgroup analyses focusing on plurisexual (i.e., bi/pansexual) women, risk of revictimization was predicted by greater severity of mother-perpetrated emotional and physical maltreatment. These results suggest that girls with sexual and emotional maltreatment histories are at highest risk for revictimization. Future research identifying the biological, psychological, and social sequelae of these specific exposures may enable the development of specific intervention programs that have the potential for maximum efficacy in preventing further violence against women most at risk.

Severity of childhood maltreatment predicts reaction times and heart rate variability during an emotional working memory task in borderline personality disorder

ABSTRACT Background: Difficulties in emotion regulation are a core symptom of borderline personality disorder (BPD) and often interfere with cognitive functions, such as working memory (WM). Traumatic childhood experiences, including severe maltreatment, can contribute to emotion dysregulation, possibly mediated by changes in high-frequency heart rate variability (HF-HRV). However, it is not yet entirely understood if HF-HRV alterations underlie impaired WM during emotional distraction in BPD and if this is related to traumatic childhood experiences and to comorbid post-traumatic stress disorder (PTSD). Objective: Our aim was to investigate performance (reaction times, RTs) and HF-HRV during an emotional working memory task (EWMT) in relation to childhood maltreatment severity and comorbid PTSD in BPD. Method: Eighty-one women (n = 28 healthy controls (HC) and n = 53 BPD patients of which n = 18 had comorbid PTSD) performed an adapted Sternberg item recognition WM task with neutral and negative social cues (interpersonal scenes from the International Affective Picture System (IAPS), and neutral, fearful, and angry faces) as distractors. Dependent variables were RTs of correct trials and HF-HRV. Childhood maltreatment was assessed with the Childhood Trauma Questionnaire. Results: Compared to healthy participants, patients with BPD showed prolonged RTs across all distractor conditions with social cues, regardless of their emotional valence. Patients with BPD, especially those with PTSD, demonstrated reduced HF-HRV both at rest and during EWMT. Severity of childhood maltreatment predicted longer RTs and lower HF-HRV during the EWMT. Conclusions: Findings suggest that adverse childhood experiences accelerate difficulties in shifting attention away from social information and that these are more pronounced in individuals with BPD. Reduced HF-HRV (low parasympathetic-tonus) may be an important psychophysiological mechanism underlying impaired WM in the presence of distracting social cues in patients with BPD, especially in those with comorbid PTSD. HIGHLIGHTS This study provides evidence that childhood maltreatment experiences are associated with hypersensitivity to social information and reduced high-frequency heart rate variability during a working memory task in borderline personality disorder.

Inflammation, amygdala-ventromedial prefrontal functional connectivity and symptoms of anxiety and PTSD in African American women recruited from an inner-city hospital: Preliminary results

Inflammatory stimuli have been shown to impact brain regions involved in threat detection and emotional processing including amygdala and ventromedial prefrontal cortex (vmPFC), and to increase anxiety. Biomarkers of endogenous inflammation, including inflammatory cytokines and C-reactive protein (CRP), are reliably elevated in a subset of patients with depression and anxiety-related disorders such as post-traumatic stress disorder (PTSD), and have been associated with high anxiety in population studies. We previously reported that plasma CRP and cytokines in patients with depression were negatively correlated with resting-state functional connectivity (FC) between right amygdala and vmPFC, as assessed using both ROI to voxel-wise and targeted FC approaches, in association with symptoms of anxiety, particularly in patients with comorbid anxiety disorders or PTSD. To determine whether relationships between inflammation, right amygdala-vmPFC FC, and anxiety are reproducible across patient samples and research settings, we employed an a priori, hypothesis-driven approach to examine relationships between inflammation, targeted right amygdala-vmPFC FC and anxiety in a cohort of African American (AA) women (n = 54) recruited from an inner-city hospital population reliably found to have higher levels of inflammation (median CRP ∼ 4 mg/L) as well as symptoms of anxiety, depression and PTSD. Higher concentrations of plasma CRP were associated with lower right amygdala-vmPFC FC (r = −0.32, p = 0.017), and this relationship remained significant when controlling for age, body mass index and number of lifetime trauma events experienced, as well as severity of PTSD and depression symptoms (all p < 0.05). This amygdala-vmPFC FC was similarly associated with a composite score of three inflammatory cytokines in a subset of women where plasma was available for analysis (n = 33, r = −0.33, p = 0.058; adjusted r = −0.43, p = 0.026 when controlling for covariates including PTSD and depression symptom severity). Lower right amygdala-vmPFC FC was in turn associated with higher levels of anxiety reported to be generally experienced on the State-Trait Anxiety Inventory, trait component (adjusted r = −0.32, p = 0.039 when controlling for covariates). Exploratory analyses also revealed a negative correlation between severity of childhood maltreatment and right amygdala-vmPFC FC (r = −0.32, p = 0.018) that was independent of CRP and its association with FC, as well as an association between low amygdala-vmPFC FC and severity of PTSD symptoms, specifically the re-experiencing/intrusive symptom subscale (adjusted r = −0.32, p = 0.028 when controlling for covariates). While CRP was not linearly associated with either anxiety or PTSD symptoms, CRP concentrations were higher in women reporting clinically significant anxiety or PTSD symptom severity when these symptoms were considered together (both p < 0.05), but with no interaction. These results support our primary hypothesis that higher inflammation was associated with lower amygdala-vmPFC FC, a relationship that was detected using a hypothesis-driven, targeted approach. Findings also support that this phenotype of high CRP and low vmPFC FC was observed in association with anxiety in primary analyses, as well as symptoms of PTSD in exploratory analyses, in a cohort recruited from an inner-city population of AA women enriched for high inflammation, history of trauma exposure, and symptom severity. Larger, longitudinal samples are required to fully tease apart causal relationships between inflammatory biomarkers, FC and PTSD-related symptoms in future studies.

Mu Opioid Receptor Dynamics in Healthy Volunteers with a History of Childhood Maltreatment.

Evidence suggests that adults with a history of childhood maltreatment, the experience of emotional or physical neglect and/or abuse within the family during childhood, have blunted reward and stress processing, and higher risk of depression. The mu opioid receptor rich nucleus accumbens and amygdala are critical to reward and stress processing respectively. We hypothesized that nucleus accumbens and amygdala mu opioid receptor densities and activity (change in receptor binding due to endogenous opioid release or receptor conformation change) were negatively associated with childhood maltreatment in healthy young adults.Maltreatment was assessed with the Childhood Trauma Questionnaire (CTQ). Healthy participants, n = 75 (52% female) completed [11C]carfentanil positron emission tomography imaging labeling mu opioid receptors. The relationship between CTQ score and binding potential (BPND, proportional to density of unoccupied receptors) was evaluated with a linear mixed effects model.No significant relationship was found between CTQ score and BPND (f = 3.28; df = 1, 73; p = 0.074) or change in BPND (activity) (t = 1.48; df = 198.3; p = 0.14).This is the first investigation of mu opioid receptors in those with childhood maltreatment. We did not identify a significant relationship between mu opioid receptor dynamics and severity of maltreatment in those without psychopathology. Because this cohort has a low CTQ score average, this may indicate that those with low severity of maltreatment may not have associated changes in mu opioid receptor dynamics. Future directions include evaluating a cohort with increased severity of childhood maltreatment.

The assessment of childhood maltreatment and its associations with affective symptoms in adulthood: Results of the German National Cohort (NAKO)

Objectives Childhood maltreatment affects 20–30% of the German population and is an important risk factor for physical and mental diseases in adult life. This study reports first results of the distribution of childhood maltreatment in the population-based mega cohort German National Cohort (NAKO) and estimates associations with affective symptoms in adulthood. Methods The Childhood Trauma Screener (CTS), a short version of the Childhood Trauma Questionnaire, was used in 83,995 adults (age: 20–72 years; 47.3% men) of NAKO. The five-item CTS assesses the severity of three types of childhood abuse and two types of childhood neglect. Results Overall, 21,131 participants (27.5%) reported at least one type of childhood maltreatment; 14,017 participants (18.3%) reported exactly one type and 250 participants (0.3%) reported all five types of childhood maltreatment. Small differences regarding age (mean absolute deviation around the mean (MAD)=0.47), sex (MAD = 0.07) and education (MAD = 0.82) were observed. The severity of childhood maltreatment was associated with more severe symptoms of depression (β = 0.23), anxiety (β = 0.21) and perceived stress (β = 0.23) in adulthood, validated particularly for emotional abuse and emotional neglect. Conclusions The distribution of childhood maltreatment in NAKO is similar to previous reports. Additionally, our results suggest differential associations with psychopathological symptoms for the five types of childhood maltreatment.

Turkish adaptation study of the computer assisted maltreatment inventory (CAMI) and its relation to psychological symptoms

ABSTRACT The Computer Assisted Maltreatment Inventory (CAMI) is an extensive measure of childhood maltreatment, consisting of sexual abuse, physical abuse, exposure to interparental violence (IPV), psychological abuse, and neglect. The purpose of the present study was to examine the psychometric properties of the CAMI in a Turkish sample. This study also aimed to investigate the prevalence and severity of childhood maltreatment and associated psychopathology in a non-Western context. The sample included 561 participants with a mean age of 24.72 (SD = 6.90) years. Participants filled out the CAMI, Childhood Trauma Questionnaire Short-Form, Two-Dimensional Social Desirability Scale, and Symptom Assessment-45 Questionnaire online. The results revealed that the Turkish version of the CAMI is an adequate retrospective measure of childhood maltreatment. Maltreatment types revealed some differences in both prevalence and severity rates in the Turkish sample compared to the original CAMI study. In the Turkish sample, the prevalence rates of physical abuse, IPV, and sexual abuse were higher than those obtained in the original study with a sample of American university students. The current results further indicated that individuals who were exposed to greater levels of sexual abuse, physical abuse, and neglect in childhood were more likely to show depression, hostility, and phobic anxiety in adulthood, respectively. Importantly, the severity of psychological abuse predicted all types of psychological symptoms. The results are discussed in light of the current literature.

The case for a diversion option to trauma-informed community-based primary mental health services for young people following early encounters with police.

There is a convergence between the peak age of onset of mental illness, offending behaviour and associated risk of crime victimization. This study compared self-reported childhood maltreatment and mental health outcomes among a cohort of help-seeking young people who disclosed either a prior criminal charge, crime victimization, or both, to those who did not report any such experiences. The outcomes may inform the development of a diversion option for young people at a first or early encounter with police. The Transitions Study (N= 802; mean age=18.3 years; 66% female) baseline and 12-month follow-up data were analysed in relation to childhood maltreatment (Childhood Trauma Questionnaire) and changes in mental health (Kessler Psychological Distress Scale and Social and Occupational Functioning Assessment Scale) among young people attending headspace centres in Australia. Outcomes were compared between those young people reporting a prior criminal charge and/or crime victimization and those who did not. Young people who reported a prior criminal charge or crime victimization reported higher frequency and severity of childhood maltreatment, than those who did not. Both groups reported a reduction in psychological distress following youth mental health service access at 12-month follow-up, however functional improvement was only evident for young people who did not report a prior criminal charge or crime victimization. Higher rates of reported childhood maltreatment and reduced psychological distress following service access supports trialling a diversion option to a trauma-informed community-based primary mental health service for young people following an early encounter with police.

Childhood maltreatment and trauma is common and severe in body dysmorphic disorder

BackgroundChildhood maltreatment and trauma may be risk factors for the development of body dysmorphic disorder (BDD). However, the limited research to date on these topics has been constrained by either the absence of a matched healthy control group or non-comprehensive assessments. MethodsThis study assessed the prevalence and severity of childhood maltreatment and other traumatic events in 52 BDD participants (56% female) and 57 matched controls (51% female) with no history of mental illness, using the Childhood Trauma Questionnaire and a checklist assessing broader traumatic events. ResultsIn comparison with controls, participants with BDD showed a higher prevalence of emotional abuse (61.5% vs. 33.3%) and physical neglect (59.6% vs. 28.1%), as well as more severe overall maltreatment, emotional abuse, and emotional and physical neglect. BDD participants were also more likely to meet cut-offs for multiple types of maltreatment and reported an elevated number and variety of broader traumatic childhood events (e.g., life-threatening illness). In BDD, increasingly severe maltreatment was correlated with greater severity of BDD symptoms, anxiety and suicidal ideation. ConclusionsThese data suggest that childhood maltreatment and exposure to other traumatic events are common and severe in BDD and are cross-sectionally associated with the severity of clinical symptoms. Adversity linked to maladaptive family functioning during childhood may therefore be especially relevant to people with BDD and could relate to social and emotional processing problems in the disorder.

Patterning of individual variability in neurocognitive health among South African women exposed to childhood maltreatment

There are individual differences in health outcomes following exposure to childhood maltreatment, yet constant individual variance is often assumed in analyses. Among 286 Black, South African women, the association between childhood maltreatment and neurocognitive health, defined here as neurocognitive performance (NP), was first estimated assuming constant variance. Then, without assuming constant variance, we applied Goldstein’s method (Encyclopedia of statistics in behavioral science, Wiley, 2005) to model “complex level-1 variation” in NP as a function of childhood maltreatment. Mean performance in some tests of information processing speed (Digit-symbol, Stroop Word, and Stroop Color) lowered with increasing severity of childhood maltreatment, without evidence of significant individual variation. Conversely, we found significant individual variation by severity of childhood maltreatment in tests of information processing speed (Trail Making Test) and executive function (Color Trails 2 and Stroop Color-Word), in the absence of mean differences. Exploratory results suggest that the presence of individual-level heterogeneity in neurocognitive performance among women exposed to childhood maltreatment warrants further exploration. The methods presented here may be used in a person-centered framework to better understand vulnerability to the toxic neurocognitive effects of childhood maltreatment at the individual level, ultimately informing personalized prevention and treatment.

Development and validation of a self-report measure assessing failures in the mentalization of trauma and adverse relationships

BackgroundThe way people process trauma and adverse relationships may be more predictive of subsequent adaptation than trauma exposure in itself. However, there is currently no self-report instrument assessing failures in the mentalization of trauma and adverse relationships. ObjectiveWe developed the Failure to Mentalize Trauma Questionnaire (FMTQ) and evaluated its psychometric properties. The FMTQ is a 29-item self-report instrument designed to assess different indications of failures in the mentalization of trauma and adverse relationships. Participants and settingA total of 975 participants (84 % women; 37 % exposed to child maltreatment) were recruited in the course of larger research protocols on parenting. MethodsParticipants completed the FMTQ and measures of childhood maltreatment, psychopathology (post-traumatic stress symptoms, dissociative symptoms, level of personality dysfunction), general mentalization and intimate partner violence. ResultsExploratory factor analysis, supported by a confirmatory factor analysis, identified seven factors with good internal consistency that corresponded to different types of failures in the mentalization of trauma and adverse relationships and that loaded on a general factor. A dose-effect association was observed between the severity of childhood maltreatment, and the severity of failures in the mentalization of trauma and adverse relationships (rs = .49, p < .01). The FMTQ total score explained a significant proportion of variance in psychopathology and intimate partner violence, both in participants with histories of childhood maltreatment and participants without childhood maltreatment. ConclusionThe FMTQ is a promising, concise and efficient measure of failures in the mentalization of trauma and adverse relationships that may facilitate clinical screening and research with adults who experienced trauma.

The role of reward sensitivity and childhood maltreatment in predicting nonsuicidal self-injury.

Findings from prior research on reward sensitivity in nonsuicidal self-injury (NSSI) have been mixed. Childhood maltreatment is an independent risk factor for NSSI and for hyposensitivity to rewards. This study aimed to disentangle the role of reward sensitivity as a predictor of NSSI for those with an elevated severity of childhood maltreatment. In a diverse undergraduate sample (N=586), trait reward sensitivity (i.e., behavioral approach system subscales) and the severity of maltreatment were assessed as predictors of a lifetime history of NSSI. In a subset of this sample (n=51), predictors of NSSI urge intensity were measured using ecological momentary assessment. Individuals with elevated maltreatment who reported less positive responsiveness to rewards were more likely to have a lifetime history of NSSI. Those with elevated maltreatment who reported a lower likelihood to approach rewards experienced more intense NSSI urges across the ten-day observation period. However, those with elevated maltreatment who reported a greater likelihood to approach rewards experienced less intense NSSI urges. The role of reward sensitivity as a cognitive risk factor for NSSI varies depending on childhood maltreatment history. Findings indicate that, for those with elevated maltreatment, hypersensitivity to approaching rewards may decrease risk for NSSI urges.
