Association between childhood trauma and white matter deficits in first-episode schizophrenia

ObjectiveThis study aimed to investigate the relationship between childhood trauma (ChT) and white matter (WM) deficits in first-episode schizophrenia (FES). MethodsA total of 103 individuals with FES and 206 healthy control individuals (HCs) were enrolled and assessed based on ChT Questionnaire (CTQ) and Positive and Negative Symptoms Scale (PANSS). Diffusion tensor imaging was acquired on a Signa 3.0 T scanner. Map of fractional anisotropy (FA) was analyzed using Tract-Based Spatial Statistics. Hierarchical logistic regression analyses were used to examine associations of sociodemographic characteristics, total CTQ scores, and WM deficits. ResultsCompared with the HCs group, the FES group showed significantly lower FA in several WM bundles (left anterior thalamic radiation, left inferior frontal-occipital fasciculus, left cingulum, forceps major, and forceps minor), and the mean FA value in these WM bundles was inversely related to the total CTQ score. In addition, a higher CTQ score may increase the risk of schizophrenia, while higher FA values may decrease the risk of schizophrenia. ConclusionThis study demonstrates that individuals with FES evince widespread cerebral WM abnormalities and that these abnormalities were associated with ChT. These results provide clues about the neural basis and potential biomarkers of schizophrenia.

Regional superficial amygdala resting-state functional connectivity in adults infers childhood maltreatment severity.

Childhood maltreatment (CM) is a potential risk factor for some neuropsychiatric disorders in adulthood (e.g. depression and anxiety) and alters trajectories of brain development. Accumulating evidence suggests that functional connectivity of the limbic system, especially the amygdala, is highly associated with childhood maltreatment, although not all studies have found this. These inconsistent results may be due to differential alterations of amygdala resting-state functional connectivity (rsFC) following childhood maltreatment. Our aim was to investigate the relationship between the rsFC of amygdala subregions and CM severity, as well as to develop a stable rsFC-based model for inferring the severity of CM. In this study, we employed the Childhood Trauma Questionnaire (CTQ) to assess CM severity in each individual. We explored the relationship between the rsFC of amygdala subregions (i.e. centromedial -CMA, basolateral -BLA, superficial-SFA amygdala) and CM experience in a discovery dataset of n=110 healthy Chinese participants by linear multiple regression analysis. Subsequent dimensional and categorical approach were performed to elucidate the relationship between rsFCs and CM severity and CM subtypes, respectively. A support vector regression model was then conducted to validate the associations between rsFCs and total CTQ scores. Moreover, we also verified the model into another independent replication dataset (n=38). Our findings suggested that childhood maltreatment was negatively associated with rsFC between the right superficial amygdala and perigenual anterior cingulate cortex (pgACC)/postcentral gyrus (PCG) but not the other two amygdala subregions. Moreover, SFA-pgACC coupling was more associated with physical neglect whereas the SFA-PCG was more related to emotional neglect. In addition, supervised machine learning confirmed that using these two rsFCs as predictors could stably estimate continuous maltreatment severity in both discovery and replication datasets. The current study supports that the rsFCs of superficial amygdala are related to childhood maltreatment and which may be a potential biomarker for the effects of childhood maltreatment-related psychiatric disorders (i.e. depression and anxiety).

Aggression and its association with childhood trauma in euthymic bipolar disorder patients

IntroductionAggression and negative behaviours are used to be present in individuals with bipolar disorder, who are sensitive to life events. Thus, many studies investigated the emergence of impulsivity and aggression in the developmental process and revealed its relationship with childhood adversities.ObjectivesThe aim of this study was to determine the relationship between childhood trauma and aggressive behaviour in euthymic patients with bipolar disorder.MethodsIt was a cross-sectional descriptive and analytical study involving patients diagnosed with bipolar disorder and followed in the psychiatric department at the University Hospital ofSfax (Tunisia).All subjects completed the Childhood trauma questionnaire (CTQ) and the Buss–Perry Aggression Scale (BPAS). Euthymiawas defined as a score on the Montgomery-Åsberg Depression Rating Scale (MADRS) not higher than 14 and by a score on theYoung Mania Rating Scale (YMRS)not higher than seven.ResultsWe included 35 patients. Their mean age was 46.69 ± 12.01 years with a sex ratio (M/F) =0.45. Most of them lived in urban areas (91.42%) and had a moderate socioeconomic level(88.57%).The most frequent trauma type was physical neglect with 74.28%, followed by emotional abuse (42.85%), emotional neglect (42.85%), physical abuse (37.14%) and sexual abuse (31.42%).The mean score of CTQ was 58.57 ±9.51. Theaverage total score of BPAS was 82.26 ±14.57.The mean scores of subscales of BPAS were 25.49±4.59 for physical aggression, 13.74±3.51for verbal aggression, 19.14±6.22 for anger and 23.89±5.57 for hostility.A statistically significant and positive correlation was determined between CTQ and BPAS (p=0.011). The score of BPAS was significantly correlated with physical abuse (p=0.003) and physical neglect (p=0.014).Conclusions The relationship between CTQ and BGHA scores suggests the possibility that childhood trauma may be one determinant of aggression in patients with bipolar disorder. Considering the childhood trauma history in the evaluation of these patients may prevent their aggression and thus their psychosocial functioning.Disclosure of InterestNone Declared

Course of bipolar disorder in patients with Childhood maltreatment

IntroductionPatients with mood disorders have the greater frequency of childhood trauma compared with the general population, and adverse childhood experiences can exert a negative impact on their clinical course. Therefore, many studies confirmed the relationship between childhood traumas and the disadvantageous features of the illness course.ObjectivesThe aim of this study was to determine the impact of negative childhood experiences on the clinical course of bipolar disorder.MethodsIt was a cross-sectional descriptive and analytical study involving patients diagnosed with bipolar disorder and followed in the psychiatric department at the University Hospital of Sfax (Tunisia).Personal information form and Childhood trauma questionnaire (CTQ) were used for data acquisition. Euthymia was defined as a score on the Montgomery-Åsberg Depression Rating Scale (MADRS) not higher than 14 and by a score on the Young Mania Rating Scale (YMRS) not higher than seven.ResultsWe included 35 patients. Their mean age was 46.69 ± 12.01 years with a sex ratio (M/F)=0.45.The average onset of bipolar disorder was 28.37±10.26 years and the average disease duration was 18.26 ± 11.55 years.Almost the third of our population had a suicidal attempt (31.42%) and a violence history (28.57%). A family history of bipolar disorder was found in 57.14% of the patients.The patients have been hospitalized at least once in 42.85% of cases.Our patients have presented psychotic symptoms in 51.42% of cases and mixed characteristics in 57.14% of cases.Emotional, physical and sexual abuse were reported by 42.85%, 37.14% , 31,42% of patients, respectively, while 74,28% and 42.85% of patients reported physical neglect and emotional neglect.Early age at illness onset was significantly associated with total CTQ score (p=0.014) and the subtype sexual abuse (p=0.009). The presence of psychotic symptomswas significantly associated with total CTQ score (p=0.003) and emotional neglect (p=0.025). Physical neglect was associated with mixed characteristics (p=0.015). Emotional abuse was associated with a greater number of hospitalisations (p=0.023).ConclusionsOur results suggest that childhood trauma is associated with a more severe course of bipolar illness. Clinical assessment of patients with bipolar disorder should include investigation of exposure to childhood trauma in order to determine appropriate therapeutic strategies.Disclosure of InterestNone Declared

Differential associations of childhood adversity subtypes and psychopathology in men and women

IntroductionPrior evidence suggests that men and women might be differentially susceptible to distinct types of childhood adversity (CA), but research on gender-specific associations between CA subtypes and psychiatric symptoms is limited.ObjectivesTo test the gender-specific associations of CA subtypes and psychiatric symptoms in the general population.MethodsData from 791 twins and siblings from the TwinssCan project were used. Psychopathology and CA exposure were assessed using the Symptom Checklist-90 Revised (SCL-90) and the Childhood Trauma Questionnaire (CTQ), respectively. The associations between the total CTQ scores and SCL-90 scores (i.e. total SCL-90, psychoticism, paranoid ideation, anxiety, depression, somatization, obsessive-compulsive, interpersonal sensitivity, hostility, and phobic anxiety) were tested in men and women separately. The associations between the five CA subtypes (i.e. physical abuse, emotional abuse, sexual abuse, physical neglect, and emotional neglect) and total SCL-90 were tested in a mutually adjusted model. As exploratory analyses, the associations between all CA subtypes and the nine SCL-90 subdomain scores were similarly tested. The regression coefficients between men and women were compared using Chow’s test. All models were adjusted for age and family structure.ResultsTotal CTQ was significantly associated with total SCL-90 in men (B = 0.013, SE = 0.003, P < .001) and women (B = 0.011, SE = 0.002, P < .001). The associations with the nine symptom domains were also significant in both genders (P < .001). No significant gender differences in the regression coefficients of total CTQ were detected. The analyses of CA subtypes showed a significant association between emotional abuse and total SCL-90 in women (B = 0.173, SE = 0.030, P < .001) and men (B = 0.080, SE = 0.035, P = .023), but the association was significantly stronger in women (ꭓ2(1) = 4.10, P = .043). The association of sexual abuse and total SCL-90 was only significant in women (B = 0.217, SE = 0.053, P < .001). The associations of emotional neglect (B = 0.061, SE = 0.027, P = .026) and physical neglect (B = 0.167, SE = 0.043, P < .001) with total SCL-90 were only significant in men. The explorative analyses of SCL-90 subdomains revealed significant associations of emotional abuse with all nine symptom domains and of sexual abuse with seven symptom domains in women. Significant associations of physical neglect with six symptom domains and of emotional neglect with depression were also detected in men. No other significant associations between CT subtypes and total SCL-90 or symptom domain scores were observed in men and women.ConclusionsCA exposure was associated with diverse psychopathology similarly in both genders. However, women are more sensitive to abuse, but men are more sensitive to neglect. Gender-specific influences of CA subtypes on psychopathology should be considered in future studies.Disclosure of InterestNone Declared

Regular cannabis use is associated with history of childhood and lifetime trauma in a non-clinical community sample

Higher rate of substance use, including cannabis, has been reported in individuals with a history of childhood trauma, but less is known about the association between cannabis use with lifetime history of trauma and chronic stress, and potential gender differences in this association. This study systematically examined this association in a cross-sectional study of 841 individuals recruited between 2007 and 2012 from the community in New Haven, Connecticut. The Cumulative Adversity Index (CAI) was used to measure cumulative lifetime major life events, life trauma, and recent life events and chronic stress. Childhood Trauma Questionnaire (CTQ) was used to measure childhood trauma. Current and regular use of drugs were assessed using self-report questionnaires and objectively verified with urine drug testing. Higher rates of childhood trauma as well as lifetime trauma, and major life events were found in cannabis users, compared to non-users. The association between cannabis use with childhood trauma (total CTQ scores) was significant after controlling for age, gender, ethnicity and regular use of alcohol or cocaine. In logistic regression analysis, cannabis use had a significant positive association with major life events and lifetime trauma, but not with chronic stress, controlling for confounding factors including age, gender, ethnicity, and regular use of alcohol and cocaine. When analyzed separately, only in women the association between cannabis use and childhood trauma was significant. These associations point to further assessment of the impact of these gender differences on neurobiology of stress and cannabis misuse risk.

Intergenerational impact of childhood trauma on hair cortisol concentrations in mothers and their young infants

BackgroundAlterations in stress regulation and function of the hypothalamic-pituitary-adrenal (HPA) axis during infancy may be a risk factor for the development of psychopathology later in life. Maternal childhood trauma, depression, anxiety and stressful life events are individually associated with HPA axis dysregulation. Less is known about their interdependent influence on maternal and infant stress regulation in at risk populations. In a sample of mothers with a history of depressive-, and/or anxiety disorders and their infants we explored if a history of maternal childhood trauma, current depressive and anxiety symptomatology, and recent life events were associated with maternal and infant long-term cortisol levels three months postpartum. MethodsData were available of 89 mothers and 49 infants. All mothers fulfilled criteria for a lifetime depressive or anxiety disorder. Diagnosis was established with a diagnostic interview. Current depressive symptomatology was assessed with the Edinburgh Postnatal Depression Scale (EPDS), current anxiety with the State-Trait Anxiety Inventory (STAI), maternal childhood trauma with the Childhood Trauma Questionnaire (CTQ) and recent life events with the Everyday Problem Checklist (EPC). Maternal and infant hair cortisol concentrations (HCC) were quantified with liquid chromatography with tandem mass spectrometry (LC-MS/MS) three months after birth. Total scores of the CTQ and subscales, EPDS, STAI, and EPC were regressed on maternal and infant HCC using regression analyses. Differences in HCC regarding trauma history were tested with t-tests. Potential confounders were identified and adjusted for. ResultsIn regression analyses, a positive curvilinear relationship was found between CTQ total score and maternal HCC (n = 83, B = 0.076, SE 0.033, p = .021), but not for current depression (n = 88, B = −0.001, SE 0.011, p = .931), current anxiety (n = 88, B = 0.002, SE 0.004, p = .650) or recent life events (n = 89, B = 0.018, SE 0.032, p = .568). Analyses were adjusted for confounders. A negative linear relationship was found between maternal CTQ score and infant HCC (n = 49, β = −0.264, B = −0.006, SE 0.003, p = .052), but not for current maternal depression (n = 45, β = −0.182, B = −0.011, SE 0.008, p = .164), current maternal anxiety (n = 45, β = −0.209, B = −0.005, SE 0.003, p = .113) or recent life events (n = 46, β = −0.128, B = −0.022, SE 0.023, p = .325). Analyses were adjusted for relevant infant hair characteristics. Specifically, maternal emotional and physical neglect were related to HCC in both mothers and infants. ConclusionsResults suggest that maternal childhood trauma is more prominent in altering maternal and infant long-term cortisol levels than perinatal depressive and anxiety symptomatology or recent life stressors in mothers with a history of depressive and/or anxiety disorders, and their infants. As infants of mothers with psychopathology are at increased risk for later psychiatric disease, future studies should investigate the interplay of possible risk factors for transgenerational transmission, intra-uterine programming of the HPA axis, including (epi-)genetic phenomena, of the HPA axis, and the influence of parenting impairment.

Anticipating Unipolar Depression and Bipolar Depression in young adult with first episode of depression using childhood trauma and personality.

Relevant research focusing on young adults with Unipolar Depression (UD) and Bipolar Depression (BD) is limited. The current research aims to investigate childhood trauma and personality traits in young adults with UD and BD. Two hundred and thirty-five patients in a first depressive episode (diagnosed UD and BD), 16-25 years old, were recruited from Second Xiangya Hospital. And 79 healthy controls (HC) were recruited from the community to form the comparison group. Patients' childhood trauma was measured by the Childhood Trauma Questionnaire (CTQ), and personality was measured by Eysenck Personality Inventory (EPI). The Kruskal-Wallis test was used to compare depression, anxiety, CTQ, and EPI scores between the HC (n = 79), UD (n = 131), and BD (n = 104) groups. Factors independently associated with mood disorders and BD were determined using binary logistic regression analyses. Compared with HC, mood disorders had more severe anxiety and depression symptoms, and higher CTQ. Emotional abuse (OR = 1.47; 95% CI = 1.08-2.01), emotional neglect (OR = 1.24; 95% CI = 1.05-1.46), and neuroticism (OR = 1.25; 95% CI = 1.16-1.35) were associated with significantly increased odds of mood disorders. Whereas, higher extraversion scores were a protective factor for mood disorders. Compared with UD, BD had more severe anxiety symptoms, and higher CTQ, than extraversion and neuroticism personality scores. Anxiety (OR = 1.06; 95% CI = 1.02-1.08) and extraversion (OR = 1.05; 95% CI = 1.03-1.09) were associated with significantly increased odds of BD. Interventions to prevent childhood trauma may improve young adults' mental health. Using childhood trauma and personality to anticipate BD and UD creates more accurate treatment for young adults with first depression.

Temporal stability and state-dependence of retrospective self-reports of childhood maltreatment in healthy and depressed adults.

Retrospective self-reports of childhood maltreatment (CM) are widely used. However, their validity has been questioned due to potential depressive bias. Yet, investigations of this matter are sparse. Thus, we investigated to what extent retrospective maltreatment reports vary in relation to longitudinal changes in depressive symptomatology. Two-year temporal stability of maltreatment reports was assessed via the Childhood Trauma Questionnaire (CTQ). Diagnosis of major depressive disorder (MDD) and depressive symptoms were assessed using the Structured Clinical Interview for DSM-IV and the Beck Depression Inventory (BDI). We included a total of n = 419 healthy controls (HC), n = 347 MDD patients, and a subsample with an initial depressive episode between both assessments (n = 27), from two independent cohorts (Marburg-Münster-affective-disorders-cohort-study and Münster-Neuroimaging-cohort). Analysis plan and hypotheses were preregistered prior to data analysis. Dimensional CTQ scores were highly stable in HC and MDD across both cohorts (ICC = .956; 95% CI [.949, .963] and ICC = .950; 95% CI [.933, .963]) and temporal stability did not differ between groups. Stability was lower for cutoff-based binary CTQ scores (K = .551; 95% CI [.479, .622] and K = .507; 95% CI [.371, .640]). Baseline dimensional CTQ scores were associated with concurrent and future BDI scores. However, longitudinal changes in BDI scores predicted variability in dimensional CTQ scores only to a small extent across cohorts (b = 0.101, p = .009, R² = .021 and b = 0.292, p = .320), with the effect being driven by emotional maltreatment subscales. Findings suggest that the CTQ provides temporally stable self-reports of CM in healthy and depressed populations and is only marginally biased by depressive symptomatology. A dimensional rather than binary conceptualization of maltreatment is advised for improving psychometric quality. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Impact of Childhood Trauma and Adult Separation Anxiety Disorder on Quality of Life in Individuals with Schizophrenia.

Childhood trauma and anxiety disorders are common in individuals with schizophrenia. This study aimed to investigate the effects of childhood trauma and adult separation anxiety disorder on the quality of life of individuals with schizophrenia. This cross-sectional study included 111 individuals with schizophrenia and 85 control subjects. The separation anxiety symptom inventory (SASI), adult separation anxiety questionnaire (ASAQ), Positive and Negative Syndrome Scale (PANSS), childhood trauma questionnaire (CTQ), and World Health Organization quality of life questionnaire (WHOQoL-BREF) were administered to the participants. More individuals with schizophrenia than control subjects were unemployed and single (p<0.05). Individuals with schizophrenia scored significantly higher on the SASI, ASAQ, and CTQ (p<0.05), whereas the control subjects scored significantly higher on the WHOQoL-BREF (p<0.05). ASAQ scores had mild positive correlations with total PANSS and PANSS subscale scores, and moderate positive correlations with total CTQ, CTQ emotional subscale scores, and CTQ physical abuse subscale scores. A negative moderate correlation was found between ASAQ and total WHOQoL-BREF scores. Mediation analysis revealed that CTQ scores significantly affected total WHOQoL-BREF and ASAQ scores. The model pathway for ASAQ scores showed a significant direct and indirect effect of CTQ on the total WHOQoL-BREF scores. Childhood trauma predicts adult separation anxiety disorder, which partially mediates the impact of childhood trauma on quality of life in individuals with schizophrenia. Therapeutic interventions for adult separation anxiety disorder in individuals with schizophrenia and a history of childhood trauma may help increase their quality of life.

Cingulate cortical thickness in cocaine use disorder: mediation effect between early life stress and cocaine consumption.

The cingulate gyrus is implicated in the neurobiology of addiction, such as chronic cocaine consumption. Early life stress (ELS) is an important moderator of cocaine use disorder (CUD). Therefore, we investigated the effect of CUD on cingulate cortical thickness and tested whether a history of ELS could influence the effects of CUD. Participants aged 18-50 years (78 with CUD due to crack cocaine consumption and 53 healthy controls) underwent magnetic resonance imaging and the cingulate thickness (rostral anterior, caudal anterior, posterior, and isthmus regions) was analysed. The clinical assessment comprised the Childhood Trauma Questionnaire (CTQ) and the Addiction Severity Index. Group comparisons adjusting by sex, age, and education were performed. Mediation models were generated where lifetime cocaine use, CTQ score, and cortical thickness corresponded to the independent variable, intermediary variable, and outcome, respectively. Group comparisons revealed significant differences in six out of eight cingulate cortices, showing lower thickness in the CUD group. Furthermore, years of regular cocaine use was the variable most associated with cingulate thickness. Negative correlations were found between CTQ scores and the isthmus cingulate (right hemisphere), as well as with the rostral anterior cingulate (left hemisphere). In the mediation analysis, we observed a significant negative direct effect of lifetime cocaine use on the isthmus cingulate and an indirect effect of cocaine use mediated by CTQ score. Our findings suggest that a history of ELS could aggravate the negative effects of chronic cocaine use on the cingulate gyrus, particularly in the right isthmus cingulate cortex.

LBODP091 The Reasons For Loss To Follow-up Of Patients With Gender Dysphoria

Abstract Aim To assess the effect of social function, motivation, support, and traumatic childhood experiences on follow-up behavior of patients with gender dysphoria (GD). Method: All the patients with GD who came to our clinic for endocrinological visit between September 2020 and July 2021 were asked to participate in this cross-sectional study. People with GD that provided consent were included in trans group. We also assigned age-matched cis-gender healthy controls. Data regarding gender transition process were collected retrospectively from medical charts. All the participants were administered Social Adaptation Self-evaluation Scale (SASS), Childhood Trauma Questionnaire (CTQ), and Multidimensional Scale of Perceived Social Support (MSPSS). The results were compared between groups. Results The study included 50 male-to-female with GD (MtF), 50 female-to-male with GD (FtM), 48 cis-females, 28 cis-males. The ratio of regular follow-up was higher in FtMs (n=48, 77.1%) than MtFs (n=39, 56.4%) (p&amp;lt;0. 05). Among lost to follow-up patients with GD, MtFs (n=17, %64.7) had a higher suicide rate than FtMs (n=11, %9.1) (p&amp;lt;0. 05). MtFs had lower CTQ and emotional abuse scores and higher sexual abuse scores than FtMs (p&amp;lt;0. 05). Conclusion Childhood traumas, emotional and sexual abuse may serve the reason for the loss to follow-up of MtFs. Presentation: No date and time listed

Assessing Childhood Maltreatment Exposure in Patients Without and With a Diagnosis of Substance Use Disorder.

Childhood maltreatment (CM), widely held as a risk factor for substance use disorders (SUDs), is commonly assessed using the Childhood Trauma Questionnaire (CTQ). Retrospective self-reports are, however, potentially subject to bias. We used a unique patient sample with prospectively documented CM to examine the performance of the CTQ and how this is affected by the presence of SUD. Analysis was based on a total of 104 individuals. Subjects with prospectively recorded CM were identified from a specialized childhood trauma unit in Linköping, Sweden (n = 55; 31 with SUD, 61% females; 24 without SUD, 71% females). Clinical controls had SUD but no CM (n = 25, 48% females). Healthy controls had neither SUD nor CM (n = 24, 54% females). We analyzed the agreement between retrospective CTQ scores and prospectively documented CM by κ analysis and assessed the performance of the CTQ to identify CM exposure using receiver operating characteristic (ROC) analysis. Agreement between prospectively and retrospectively recorded CM exposure was poor for sexual abuse (36.6%, Cohen κ = 0.32, P = 0.008) and physical abuse (67.3%, κ = 0.35, P = 0.007). Overall CTQ performance was fair (ROC: area under the ROC curve = 0.78, optimal cutoff = 36.5, sensitivity = 0.65, specificity = 0.75). However, performance was excellent in the absence of SUD (area under the ROC curve = 0.93, cutoff = 32.0, sensitivity = 0.88, specificity = 0.88), but poor in participants with lifetime SUD (area under the ROC curve = 0.62, cutoff = 42.0, sensitivity = 0.60, specificity = 0.36). These data support the CTQ as a tool to assess CM exposure but suggest that it may be less useful in patients with SUD.

Test-retest reliability of the Childhood Trauma Questionnaire in psychotic disorders

BackgroundChildhood trauma is common and associated with worse psychiatric outcomes. Yet, clinicians may not inquire about childhood trauma due to a misconception that patients cannot provide reliable reports. The goal of this study was to examine the reliability of self-reports of childhood trauma in psychotic disorders. MethodsWe examined the test-retest reliability of the Childhood Trauma Questionnaire (CTQ) in schizophrenia (SZ, n = 19), psychotic bipolar disorder (BD, n = 17), and healthy control (HC, n = 28) participants who completed the CTQ on ≥2 occasions over variable time periods (mean 19.6 months). We calculated the intraclass correlation (ICC) for the total CTQ score, each of the five CTQ domains, and the minimization/denial subscale for the three groups. For any CTQ domains showing low test-retest reliability (ICC < 0.61), we also explored whether positive, negative, depressive, and manic symptom severity were associated with CTQ variability. ResultsWe found high ICC values for the total CTQ score in all three groups (SZ 0.82, BD 0.85, HC 0.88). The ICC values for CTQ subdomains were also high with the exceptions of scores for sexual abuse in BD (0.40), emotional neglect in SZ (0.60), and physical neglect in BD (0.51) and HC (0.43). In exploratory analyses, self-reports of sexual abuse in BD were associated with greater severity of depressive symptoms (β = 0.108, p = 0.004). ConclusionsPatients with SZ and BD can provide reliable self-reports of childhood trauma, especially related to physical and emotional abuse. The presence of psychosis should not deter clinicians from asking patients about childhood trauma.

The Multidimensional Inventory of Dissociation (MID) in Depersonalization Disorder: General Findings with a Clinical Emphasis on Memory and Identity Disturbances

ABSTRACT The Multidimensional Inventory of Dissociation (MID) was administered to 23 participants diagnosed with DSM-IV-TR Depersonalization Disorder (DDD) by structured interview. The MID has not been previously examined in DDD and does not generate a diagnostic formula for the disorder. Mean MID score for the sample was modestly elevated at 18.54, and was significantly correlated with Dissociative Experiences Scale, Cambridge Depersonalization Scale, and Childhood Trauma Questionnaire scores. Criterion A (General Dissociation) Depersonalization and Depersonalization scale scores were markedly elevated (41.70 and 40.98 respectively), followed by moderate elevations in the Identity Confusion (36.01), Trance (25.44), and Memory Problems (23.30) scales. Criterion B (Intrusions from partly dissociated self-states) mean score was modestly elevated (19.13) and declined to 13.67 once items overlapping with the Depersonalization and Identity Confusion scales were excluded. Criterion C (fully dissociated manifestations of other self-states) mean score was minimally elevated (6.57). Of the 168 pathological dissociation items, 55 were clinically elevated in DDD. Closer examination of the Intrusions and Amnesia items that were modestly elevated in DDD revealed that these items did not reflect the presence of alters, but rather represented known depersonalization-related phenomena. We propose a preliminary formula, based on cutoff scores for Criterion A Depersonalization and/or Derealization, Criterion B, and Criterion C (≥20, ≤28, ≤11) for the sensitive diagnosis of DDD (82.6% of participants), which would require future investigation for replication and determination of specificity vis-à-vis the other dissociative disorders.

Childhood trauma and gender: Synergistic and additive effects on sleep in healthy young adults

ObjectivesTo examine whether gender moderates the effects of childhood trauma on subjective and objective sleep measures. DesignSecondary data analysis, exploratory SettingsSleep research lab ParticipantsA total of 213 men and 278 women aged 18-30 completed subjective measures. A subsample of 172 participants without any psychiatric, medical, or sleep disorders completed objective polysomnography for 1 night at baseline, before sleep manipulation. MeasurementsSubjective measures: Childhood Trauma Questionnaire (CTQ), Pittsburgh Sleep Quality Index, Insomnia Severity Index, and Epworth Sleepiness Scale. Objective measures: Standard polysomnography measures. Multiple regressions determined whether gender moderated CTQ score on any objective or subjective sleep measures. If gender was not a moderator, we examined additive effects of gender and CTQ score. Models were adjusted for race and age. ResultsGender and CTQ score interactions were non-significant for both subjective (p > .675) and objective (p > .110) sleep. Women demonstrated better subjective sleep quality (Pittsburgh Sleep Quality Index, B = -0.264, p = .041) and more delta sleep than men (B = 3.032, p =.005). Greater CTQ score was associated with increased sleepiness (Epworth Sleepiness Scale, B = 0.029, p = .042), increased insomnia severity (Insomnia Severity Index, B = 0.027, p = .005), and lower REM density (B = -0.132, p = .045). ConclusionOur finding of greater delta sleep and better subjective overall sleep quality in women suggests that, among people without comorbidities, women may experience better sleep. Childhood trauma is associated with objective and subjective sleep measures, but this association is non-specific to gender. Clear links between childhood trauma and sleep are detectable in a sample of healthy sleepers with no comorbidities.

Polygenic risk for schizophrenia as a moderator of associations between childhood trauma and schizotypy

Recent evidence shows that genetic and environmental risk factors for psychotic disorders are associated with higher levels of schizotypy (or psychosis proneness) in the general population. However, little is known about how these risk factors interact. We specifically examined whether genetic loading for schizophrenia moderates the association between childhood trauma severity and schizotypy. Schizotypy was measured using the Schizotypal Personality Questionnaire (SPQ), and childhood trauma severity was measured with the Childhood Trauma Questionnaire (CTQ) among a total of 168 participants (comprising 51 healthy individuals, 56 diagnosed with schizophrenia, and 61 with bipolar disorder). Polygenic risk scores (PRS) for schizophrenia were calculated for all participants and examined as a potential moderator of associations between total scores on the CTQ and schizotypy total scores and dimensions (i.e., cognitive-perceptual, interpersonal, disorganised). Multiple linear regression models revealed associations between childhood trauma and all dimensions of schizotypy, but no associations between PRS and schizotypy. A significant interaction between PRS and childhood trauma was evident for the interpersonal and disorganised dimensions of schizotypy, as well as the total score, reflecting positive associations between childhood trauma severity and these two schizotypal dimensions, only for individuals with low or average PRS for schizophrenia. This suggests that trauma may be able to increase risk for psychosis independently of any genetic vulnerability. The present findings are consistent with the idea of several risk pathways for the development of psychotic disorders.

Investigating the Association of Criminal Behavior With Childhood Traumas, Impulsivity, and Dominant Temperaments in Bipolar I Disorder.

Objective: To examine impulsivity, dominant temperaments, and childhood trauma in patients with bipolar I disorder who committed crimes by comparing them with bipolar I patients with no criminal history and with healthy controls.Methods: A total of 144 subjects in 3 groups (62 criminal history bipolar patients, 40 non-criminal bipolar patients, and 42 controls) participated in this cross-sectional study. All participants completed the Childhood Trauma Questionnaire (CTQ), the Barratt Impulsiveness Scale (BIS-11), and the TEMPS-A (Temperament Evaluation of Memphis, Pisa, Paris, San Diego Autoquestionnaire). Subjects were enrolled in the study between April 1, 2019, and March 1, 2020.Results: The mean age was higher (P = .029) and education level lower (P = .045) among the criminal history bipolar patients than the other 2 groups. Of quantitative variables, physical abuse and emotional abuse subscales and total CTQ score were significantly higher in both patient groups compared to healthy controls (P < .001 for all scores). For dominant temperament, hyperthymic temperament scores of the criminal history bipolar group were higher than that of the control group (P < .001).Conclusions: Patients with bipolar I disorder were found to have experienced more childhood traumas, and the criminal history bipolar group and those who were admitted to prison had suffered more physical abuse. Hyperthymic temperament was dominant in bipolar I patients involved in crime. Taking into account the temperaments of bipolar I disorder in treatment plans and providing psychosocial support to these patients could help prevent violent behaviors and the possibility of crime.

Seeing the past in a new light: change in reports of childhood abuse and neglect before and after inpatient psychotherapy and its relevance for change in depression symptoms

ABSTRACT Objective As changes in mental representations have been discussed as mechanisms of change in psychotherapy, the question arises whether recollections of childhood abuse and neglect are altered as well and how they relate to symptom changes. Method Individuals in psychosomatic inpatient treatment (N = 488, 60.5% women) filled out the Childhood Trauma Questionnaire (CTQ) and Patient Health Questionnaire (PHQ-9). Changes in both were investigated with correlations and t-tests. Linear regression analysis was used to test whether CTQ changes predicted symptom changes. Network analysis was performed to ascertain structural connections between somatic and emotional-cognitive depression symptoms and CTQ subscales before and after treatment. Results After treatment (duration in days: M = 52.83, SD = 20.94), patients reported fewer depression symptoms (d = 0.84), while CTQ scores increased slightly (d = 0.11). Changes in the CTQ predicted recovery from depression symptoms in a statistically significant way (β = .133, p = .001). We did not observe changes in the overall network structure between baseline assessment and discharge. Conclusion The findings suggest that the evaluation of past experiences can change over multiple weeks of psychotherapy. Further, these updated mental representations, indicating a greater recognition of past adversity, may contribute to symptom relief.

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.
