Childhood maltreatment trauma: a comparison between patients in treatment for substance use disorders and patients in mental health treatment

The Relationship Between Self-Reported Childhood Maltreatment and Mental Health in Substance Use Disorders: A 6-Year Retrospective Analysis

OBJECTIVE

This longitudinal cohort study aims to investigate the relationship between self-reported childhood maltreatment (CM) and the retrospective trajectory of substance use, mental health, and satisfaction with life in individuals with substance use disorders.

METHODS

One hundred eleven treatment-seeking individuals with substance use disorder were recruited from clinical settings and monitored prospectively for 6 years. The participants' substance use, mental health, and satisfaction with life were assessed using standardized measures. Cluster analysis divided the cohort into two groups-low CM and high CM-based on their scores on the Childhood Trauma Questionnaire Short Form at year 6. Mixed-effects linear models were fitted to assess the association between longitudinal scores on drug use, mental health, and satisfaction with life and CM group.

RESULTS

Most participants (92%) reported at least 1 CM. Out of all participants, 36% were categorized into the high-CM group, while 59% were categorized into the low-CM group. CM group was not associated with the amount of substance or alcohol use. CM group was significantly associated with the longitudinal course of mental health and life satisfaction.

CONCLUSIONS

This study underscores the association between self-reported CM and mental health and life satisfaction in patients with substance use disorder. Our results may imply an increased risk of adverse outcomes in patients with high levels of CM, while bearing in mind that both current and retrospective mental health and substance use problems can influence the accuracy of recalling CM.

Sex and gender in psychotrauma research

Background: Posttraumatic stress disorder (PTSD) is two to three times more common in women than in men. To better understand this phenomenon, we need to know why men, women, and possibly individuals with other sex/gender identities respond differently to trauma. To stimulate sex and gender sensitive research, the European Journal of Psychotraumatology (EJPT) was the first journal to adopt a gender policy. In addition, a call for papers entitled Integrating and Evaluating Sex and Gender in Psychotrauma Research was announced.Objective: This special issue synthesizes the past five years of psychotrauma research with regard to sex/gender differences.Method: Seventy-seven articles were identified from EJPT archives, including five systematic reviews. These articles examined sex differences and/or gender differences in exposure to trauma, posttraumatic stress responses, or how sex and gender impacts (mental) health outcomes or treatment responses.Results: Findings from these studies outlined that: 1. sex and gender still need to be more clearly defined, also in relation to the context that codetermine trauma responses, like other 'diversity' variables; 2. in most studies, sex and gender are measured or reported as binary variables; 3. sex and gender are important variables when examining trauma exposure, responses to these events, symptoms trajectories, and mental and physical health outcomes across the life span; and 4. in PTSD treatment studies, including a meta-analysis and a systematic review, sex and gender were not significant predictors of treatment outcome.Conclusion: Future research must focus on sex and gender as important and distinct variables; they should include sex and gender in their statistical analyses plan to better clarify associations between these variables and (responses to) psychotrauma. To enhance reporting of comparable data across studies, we provide suggestions for future research, including how to assess sex and gender.

Childhood sexual abuse and suicide attempts in patients with substance use disorders: The mediating role of emotion dysregulation

BACKGROUND

Suicide attempts (SA) are a public health concern because of increasing prevalence and clinical implications. Childhood trauma (CT) and emotion dysregulation (ED) have been proposed as predictors of SA, but few data are available in patients with Substance Use Disorder (SUD).

OBJECTIVE

Our study aims to investigate the association of sociodemographic/clinical variables, CT typologies, and ED features with SA in SUD patients.

PARTICIPANTS AND SETTING

Subjects with SUD were screened in an outpatient setting. The final sample consisted of 226 patients, subdivided according to the presence of lifetime SA (SUD, n = 163 vs. SUD-SA, n = 63).

METHODS

Participants were compared for sociodemographic and clinical information. CT and ED were assessed through the Childhood Trauma Questionnaire - Short Form (CTQ-SF) and the Difficulties in Emotion Regulation Scale (DERS), respectively. We performed a mediation analysis to test the effect of CT and ED on SA.

RESULTS

Patients with a history of SA (27.9 %) displayed more psychiatric comorbidities (p = 0.002) and hospitalizations (p < 0.001), higher scores at CTQ-SF sexual abuse (p < 0.001) and DERS 'impulse' (p = 0.002), 'goals', 'non-acceptance', 'strategies' (p < 0.001) subscales. The relationship between CTQ-SF sexual abuse and SA was significantly mediated by DERS 'strategies' (p = 0.04; bootstrapped 95 % LLCI-ULCI = 0.004-0.024).

CONCLUSIONS

CT and different dimensions of ED were associated with SA in SUD patients. In our sample, the effects of childhood sexual abuse on SA were mediated by limited access to emotion regulation strategies. SUD patients are burdened with higher all-cause mortality, and CT and lifetime SA can worsen clinical outcomes. Clarifying the reciprocal interactions of psychopathological dimensions may help deliver targeted interventions and reduce suicide risk in specific populations.

Bridging childhood to adulthood: the impact of early life stress on acute stress responses

Background

Childhood trauma exerts enduring impacts on the physical and psychological well-being of individuals in adulthood, influencing their daily functioning. This study aims to investigate the impact of childhood trauma on stress recovery in adults, concentrating on heart rate variations during acute stress exposure.

Methods

A cohort of 126 participants completed the Childhood Trauma Questionnaire (CTQ) and underwent the Trier Social Stress Test (TSST) to elicit acute stress, with continuous heart rate (HR) monitoring for stress recovery assessment.

Results

The results revealed a negative correlation between childhood trauma and stress recovery, prominently observed in instances of emotional neglect and abuse. Individuals with heightened childhood trauma exhibited protracted stress recovery following acute stress exposure.

Conclusion

Childhood traumatic experiences were associated with the recovery from acute stress, as indicated by heart rate indices. These findings contribute to the foundational framework for psychological interventions tailored to individuals with a history of childhood trauma.

Cognitive impairment as a predictor of long-term psychological distress in patients with polysubstance use disorders: a prospective longitudinal cohort study

BACKGROUND

The association between polysubstance use disorder (pSUD), mental illness, and cognitive impairments is well established and linked to negative outcomes in substance use disorder treatment. However, it remains unclear whether cognitive impairment predicts long-term psychological distress among treatment seeking patients with pSUD. This study aimed to investigate the associations and predictive ability of cognitive impairment on psychological distress one and 5 years after treatment initiation.

METHODS

N = 164 treatment seeking patients with pSUD were sampled at treatment initiation. We examined associations between cognitive impairment according to Montreal Cognitive Assessment® (MoCA®), Wechsler Abbreviated Scale of Intelligence (WASI), and Behaviour Rating Inventory of Executive Function - Adult version (BRIEF-A) administered at treatment initiation and psychological distress defined by the Symptom Check List-90-Revised (SCL-90-R) at treatment initiation, one and five years later. We ran hierarchical logistic regressions to assess the predictive ability of the respective cognitive instruments administered at treatment initiation on psychological distress measured one and five years later including psychological distress at treatment initiation and substance intake at the time-points of the measurements as covariates.

RESULTS

The main results was that MoCA® and BRIEF-A predicted psychological distress at years one and five, but BRIEF-A lost predictive power when accounting for psychological distress at treatment initiation. WASI predicted psychological distress at year one, but not at year five.

CONCLUSIONS

Results from MoCA® and WASI was found to be less sensitive to the effect of psychological distress than BRIEF-A. Cognitive impairment at treatment initiation may hold predictive value on later psychological distress, yet its clinical utility is uncertain.

Comorbidity of Lifetime History of Abuse and Trauma With Opioid Use Disorder: Implications for Nursing Assessment and Care

BACKGROUND

Opioid use disorder (OUD) is a public health crisis and is challenging to treat. Previous research has shown correlations between OUD, abuse/trauma, and chronic pain.

AIMS

The purpose of this study was to investigate history of lifetime sexual, physical, and/or emotional abuse among participants in a medication-assisted treatment (MAT) program for OUD, and to investigate associations between abuse history and chronic pain.

METHODS

This is a secondary analysis of intake data from a 2-year, nonexperimental cohort treatment program of patients with OUD in rural Colorado. De-identified data were provided by 476 adult MAT patients using the Adult Addiction Severity Index (ASI-6). The ASI-6 includes three yes/no questions about history of abuse (emotional, physical, and sexual), with separate scoring for "past 30 days" and "lifetime" abuse.

RESULTS

Lifetime history among MAT program for OUD patients was 23% for sexual abuse, 43% for physical abuse, and 58% for emotional abuse. History of physical abuse was significantly associated with having a chronic pain diagnosis, χ2 = 4.49, p = .03, and also with higher reported pain levels, t(460) = 2.71, p = .007.

CONCLUSION

Lifetime history of physical abuse was associated with OUD and chronic pain, yet standard pain assessments do not assess these factors. In health care settings, the implementation of standardized trauma-informed screening tools, prompt recognition of abuse/trauma history, and adjunct psychological interventions may reduce stigma, reduce opioid use escalation, and help patients overcome OUD.

Childhood Trauma Questionnaire-Short Form: Evaluation of Factor Structure and Measurement Invariance

Childhood trauma is known to put individuals at risk for mental and physical challenges later in life. Retrospective assessment of early abuse and neglect is critical for prevention and intervention efforts targeted at reducing the negative impacts of childhood trauma. The Childhood Trauma Questionnaire-Short Form (CTQ-SF) is a widely used measure to assess trauma among adolescents and adults, though there are some inconsistencies with regard to its factor structure and psychometric properties. The purpose of the current study was twofold: (1) to evaluate the hypothesized five-factor structure of CTQ-SF and (2) to test measurement invariance (equivalence) of the instrument across gender and race in a large, nationally representative sample of US adults (N = 863). Confirmatory factor analysis results indicate that the five-factor model fit the data well. The results also show that the five-factor model is generally invariant by gender and racial/ethnic groups and that the form's subscales positively correlate with depression, anxiety, and abnormal inflammatory biomarker activity. Assessment is critical for the advocacy and treatment of individuals who have experienced abuse and neglect as children and adolescents. Our findings suggest that the CTQ-SF is a valuable tool for assessing childhood trauma and can be used in advocacy and treatment efforts.

Treatment of post-traumatic stress disorder and substance use disorder in adults with a history of adverse childhood experiences: A systematic review of psychological interventions

Background

Adverse childhood experiences (ACEs) have long-term effects on adult health, including unresolved trauma and substance use disorder (SUD). There are hypotheses of a mediating role of emotion regulation. This systematic literature review and narrative synthesis assessed the effectiveness of psychological interventions on emotion regulation, PTSD and SUD symptoms.

Methods

Searches were conducted using the Cochrane Handbook for Systematic Reviews methodology. Eligible studies were randomised controlled trials (RCTs) and quasi-experimental psychological interventions published between 2009 and 2019. Study characteristics, results and methodological quality were systematically analysed.

Results

Thirteen studies, including nine RCTs, were selected. Integrated SUD and PTSD treatments consisted of Seeking Safety, exposure-based treatment, Trauma Recovery and Empowerment Model, and integrated cognitive behavioural therapy. Two studies reported emotion regulation. Five studies found a small to medium positive effect size of psychological interventions on PTSD outcomes. Two studies had a small positive effect size on SUD outcomes and two a small negative effect size. Attrition was high across most studies. Characteristics likely to affect the applicability of the review were described.

Conclusion

The review found some evidence of a small inconsistent positive effect of psychological interventions on PTSD outcomes, and no evidence of effect on SUD outcomes. The range of theoretical models was narrow. Overall quality was low with high clinical heterogeneity and missing key information, particularly on emotion regulation, an important transdiagnostic feature. Further research is required to establish interventions that can treat these multiple conditions with a focus on effectiveness, acceptability, and implementation in real life clinical practice.

[Comorbidity of posttraumatic stress disorder and addiction from a biopsychosocial perspective]

Posttraumatic stress disorder and substance use disorder often co-occur within the health care system. Their comorbidity is associated with more serious acute clinical symptomatology, more frequent hospital admissions in state of emergency and significantly lower chances of improvement by psychological and pharmacological treatment. Their comorbidity contributes to dramatically unfavourable courses of illness as regards all biopsychosocial levels. The survey presented will discuss empirical findings from various perspectives: general epidemiology, substance use disorder as risk factor of trauma and PTSD, trauma and PTSD as risk factor of SUD, neurobiological effects of SUD converging towards neurobiology of PTSD, shared common factors of genetics/epigenetics, personality traits, and early developmental stress and trauma. The main focus of analysis will be put on processes that are intrinsically linked to the development and course of both disorders.

Childhood Maltreatment and Risky Substance Use Behaviors: The Mediating Roles of Posttraumatic Stress Symptoms & Callous Unemotional Traits

Background: A robust relationship has been established between childhood maltreatment and risky substance use. Posttraumatic stress symptoms and callous-unemotional (CU) traits, both of which can be consequences of childhood maltreatment, have been implicated as potential mediators of this relationship, but despite phenotypic overlap have not been examined within the same model. Objective: The current cross-sectional study examined the indirect effect of childhood maltreatment severity on risky drug and alcohol use behaviors though PTSS and CU traits. Methods: Undergraduates (n = 355, 54.4% female) with childhood maltreatment histories completed questionnaires regarding childhood maltreatment, PTSS, substance use behaviors, and CU traits. Path modeling was utilized to examine indirect effects of childhood maltreatment on risky alcohol and drug use behaviors. Results: Overall the model demonstrated good fit. PTSS and CU traits were found to fully mediate the childhood maltreatment severity to risky alcohol use behaviors, with PTSS demonstrating a trending mediational effect to risky drug usage. Results support multiple pathways to risky alcohol use for individuals with childhood maltreatment histories through PTSS and CU traits, suggesting both PTSS as well as CU traits as potential targets of intervention for alcohol misuse among individuals with childhood maltreatment experiences.

Smaller left hippocampal subfield CA1 volume is associated with reported childhood physical and/or sexual abuse in major depression: A pilot study

BACKGROUND

Smaller hippocampal volumes are reported in adults with major depressive disorder (MDD) and in reported childhood abuse. The hippocampus is a complex structure with distinct functional subfields. We sought to examine the effect of MDD diagnosis and childhood abuse on hippocampal subfields.

METHODS

Forty-one MDD participants (17 reported abuse and 24 did not) and 46 healthy volunteers (HV) (2 reported abuse) underwent T1- weighted structural magnetic resonance imaging (MRI) and clinical characterization in a retrospective design. A subfield segmentation program was used to measure the whole and subfield hippocampal volumes. Linear mixed-effects models were fitted for group comparisons.

RESULTS

No main effect of diagnosis interaction effect between diagnosis and subfield region was observed. However, a comparison of abused MDD vs. HVs showed a group by region interaction. A significant interaction between childhood abuse and region was observed. Effects were confined to the left side of the brain, and post hoc, exploratory region-specific tests indicated smaller left CA1 volume in abused MDD compared with non-abused MDD. In addition, smaller amygdala volume was found in all MDD compared with HVs.

LIMITATIONS

We did not have a sample of healthy volunteers with reported childhood abuse.

CONCLUSIONS

The diagnosis of pure MDD may not be sufficient to exert effects on hippocampal volumes, indicating the importance of taking into account childhood trauma in studies on psychopathological mechanisms. Left CA1 might be the hippocampal subfield most relevant to reported childhood abuse. Smaller amygdala volume may be related to MDD diagnosis independent of childhood abuse.

Relational recovery in co-occurring conditions: a qualitative study of first-person experiences

Purpose

The purpose of this paper is to explore and describe first-person experiences of relational recovery in co-occurring mental health and substance use conditions.

Design/methodology/approach

Within a phenomenological and collaborative approach, in-depth individual interviews with eight persons with co-occurring conditions were analysed using systematic text condensation.

Findings

Participants described interpersonal relationships as both supporting and hindering recovery in fundamental ways. Four categories of experiences of relational recovery were described as follows: choosing one’s child; living with loneliness and a painful past; sacrificing everything for one’s partner; and regaining trust and support.

Originality/value

This paper provides an enhanced understanding of how interpersonal relationships may be experienced by persons who live with co-occurring conditions. The results generally support an understanding of recovery as a relational process.

Influence of Severity of Type and Timing of Retrospectively Reported Childhood Maltreatment on Female Amygdala and Hippocampal Volume

Deleterious effects of adverse childhood experiences (ACE) on human brain volume are widely reported. First evidence points to differential effects of ACE on brain volume in terms of timing of ACE. Upcoming studies additionally point towards the impact of different types (i.e., neglect and abuse) of ACE in terms of timing. The current study aimed to investigate the correlation between retrospectively reported severity of type (i.e., the extent to which subjects were exposed to abuse and/or neglect, respectively) and timing of ACE on female brain volume in a sample of prolonged traumatized subjects. A female sample with ACE (N = 68) underwent structural magnetic resonance imaging and a structured interview exploring the severity of ACE from age 3 up to 17 using the “Maltreatment and Abuse Chronology of Exposure” (MACE). Random forest regression with conditional interference trees was applied to assess the impact of ACE severity as well as the severity of ACE type, (i.e. to what extent individuals were exposed to neglect and/or abuse) at certain ages on pre-defined regions of interest such as the amygdala, hippocampus, and anterior cingulate (ACC) volume. Analyses revealed differential type and timing-specific effects of ACE on stress sensitive brain structures: Amygdala and hippocampal volume were affected by ACE severity during a period covering preadolescence and early adolescence. Crucially, this effect was driven by the severity of neglect.

Associations between adverse childhood experiences and adversities later in life. Survey data from a high-risk Norwegian sample

BACKGROUND

A history of childhood abuse and neglect (CAN) is associated with exposure to later negative life events. CAN at an early age, multiple cooccurring exposures (cumulative events), and a high severity and frequency of exposure have potential detrimental long-term effects.

OBJECTIVE

The present study examines the relationship between the severity of CAN and the prevalence of school difficulties and hardship at school, adult adversity and mental health.

PARTICIPANTS AND SETTINGS

Participants were recruited from in- and outpatient mental health or substance abuse treatment facilities, child protective services (CPS), and prisons (N = 809, age range = 13-66, mean age = 27.62, SD = 10.47).

METHODS

Exposure to childhood maltreatment was assessed by the Childhood Trauma Questionnaire Short Form (CTQ-SF). After adjusting for gender and age, we conducted a risk ratio regression analysis to investigate associations between severity of child abuse and neglect and hardship at school, adult adversity and adult mental health.

RESULTS

The moderate and severe level groups of CAN had statistically significant higher risk ratios for experiences of school difficulties, hardship at school, adult adversity and mental health problems. A robust dose-response was found between severity levels.

CONCLUSION

At an individual level the findings highlight the association between exposure to abuse and adult adversity, underscoring the importance of targeting individuals with high risk of exposure to CAN to reduce the negative long-term risk for Polyvictimization.

Early life stress by repeated maternal separation induces long-term neuroinflammatory response in glial cells of male rats

Childhood maltreatment and neglect lead to a wide range of mental disorders highlighted by hormone and immune alterations in neglected children. This social-health challenge has led to the creation of early stress models such as maternal separation (MS) in rodents. We performed a MS model (4 h per day, 21 days; n = 16 MS and n = 16 control), and then measured three parameters in adult male rat brains, in order to look for long-term effects of early life stress. We used immunocytochemistry to mark glial fibrillary acidic protein (GFAP)-positive cells, which indicates changes in astroglia, and ionized calcium binding adaptor molecule 1 (Iba-1)-positive cells, which inform about reactive microglia. In order to study mRNA levels of some immune mediators, interleukin determination (interleukin-6, IL-6; tumor necrosis factor, TNFα) mRNAs were evaluated by real-time polymerase chain reaction (rt-PCR) in discrete brain regions. Measurements of numbers of GFAP-positive cells, and expression of Iba-1, IL-6 and TNFα mRNAs were performed in prefrontal cortex (PFC): cingulate cortex (CG), prelimbic cortex (PL) and infralimbic cortex (IL), striatal areas (dorsal striatum, STD; and nucleus accumbens, ACC), and dorsal hippocampus (HC: CA1, CA3 and dentate gyrus (DG)). We found that MS produces a dramatic and sustained decrease in the astroglial population in all the areas measured (from -25% in CA1 to -85.7% in ACC), whereas increased numbers of microglia were found, in more restricted regions: STD (72.6%), ACC (31%) and CA3 (33.3%) areas. Regarding mRNA measurements, we found increased IL-6 mRNA expression in HC (104.2%), and after MS.
