The Impact of Childhood Psychological Maltreatment on Mental Health Outcomes in Adulthood: A Systematic Review and Meta-Analysis

Construct validity of probable child maltreatment indicators using prospectively recorded information in a longitudinal cohort of Canadian children

BACKGROUND

Officially reported and self-reported measures of child maltreatment show poor agreement and may differentially predict psychosocial problems in adulthood. However, research remains primarily based on retrospective self-reports, warranting examination of the validity of prospective assessments of maltreatment.

OBJECTIVE

To assess the construct validity of prospective indicators of child maltreatment using a longitudinal cohort of Canadian children.

PARTICIPANTS AND SETTING

The population-based cohort comprises 2120 participants born between 1997 and 1998 in Quebec, Canada.

METHODS

Maternal and familial risk factors (maternal age, depressive symptoms, and antisocial behaviors, socioeconomic status, and single-parent home) and early adulthood functioning difficulties (depression, anxiety, suicidality, alcohol misuse, and unemployment status) were assessed across various time points (0-23 years). Associations between factors and prospective and retrospective maltreatment indicators were appraised.

RESULTS

Most maternal and familial risk factors (80 %) showed associations with indicators of prospective maltreatment (ΔM = +/-0.04 to 0.72; p < 0.05). Several early adulthood functioning difficulties (30 %) showed associations with physical (ΔM = 0.05 to 0.22; p < 0.05) and sexual abuse (ΔM = 0.33 to 0.34; p < 0.05), while emotional, supervisory, and physical neglect were only associated with educational/employment status (ΔM = 0.04 to 0.10; p < 0.05). Cumulatively assessed maltreatment also showed a dose-response relationship with maternal and familial risk factors/functioning difficulties.

CONCLUSIONS

The strong construct validity exhibited by our prospective indicators highlights the need to assess child maltreatment multi-modally. Our findings further contribute to the wider discussion surrounding the measurement of child maltreatment.

The role of enmeshment and undeveloped self, subjugation and self-sacrifice in childhood trauma and attachment related problems: The relationship with self-concept clarity

BACKGROUND

Schema Theory posits that childhood trauma and unmet emotional needs lead to the formation of Early Maladaptive Schemas (EMS). However, the connection between EMS and self-concept clarity remains unexplored.

OBJECTIVE

This study examines how three specific EMS- 1. Enmeshment and Undeveloped Self, 2. Subjugation, and 3. Self-Sacrifice-, relate to childhood trauma, attachment related problems, and self-concept clarity.

PARTICIPANTS AND SETTING

University students (N = 360) completed Self-report questionnaires on these constructs.

METHODS

Path models were fitted to the total scores to test whether the three EMS mediated the association between childhood trauma, attachment problems and self-concept clarity.

RESULTS

Childhood trauma was directly related to each of the three EMS, which all mediated the association between trauma and attachment anxiety. Subjugation additionally mediated the relation between trauma and attachment avoidance. Both insecure attachment styles were directly related to self-concept clarity. Attachment anxiety mediated the association between each EMS and self-concept clarity, whereas the effect of subjugation was additionally mediated by attachment avoidance.

CONCLUSIONS

Based on the results, we can conclude that childhood trauma is related to insecure attachment styles and to self-concept clarity, and that this relation is mediated by all three EMS.

Childhood trauma cortisol and immune cell glucocorticoid transcript levels are associated with increased risk for suicidality in adolescence

Rising adolescent suicide rates present a growing unmet need. Childhood trauma (CT) has been associated with altered cortisol dynamics and immune cell glucocorticoid reactivity, yet their additive longer-term contributions to later suicide outcomes are less clear. The current study compared CT scores, resting salivary free cortisol and mononuclear cell gene expression levels of the nuclear receptor, subfamily 3, member 1 (NR3C1) coding the glucocorticoid receptor, and its co-chaperons FKBP prolyl isomerase 5 (FKBP5) and KIT Ligand (KITLG), between a cohort of adolescents presenting with a suicidal crisis requiring hospital treatment, and matched healthy controls. Childhood trauma scores and glucocorticoid measures were significantly altered among suicidal adolescents, and CT scores correlated with mononuclear cell glucocorticoid transcripts. Both CT scores and glucocorticoid measures explained substantial additive portions of the variance in adolescent suicidality. Long-term perturbations in cortisol dynamics and immune cell glucocorticoid response elements denote dysregulated immune stress reactivity, and may possess value in prediction and point to modifiable-risk factors in prevention of clinically significant suicidality during the brittle period of adolescence, years after childhood trauma exposure.

Exploring the impact of child maltreatment on adult suicidal ideation and suicide attempts

BACKGROUND

The experience of child maltreatment (CM) is associated with a 2- to 3-fold increased risk of suicidal ideation and suicide attempts in adulthood. However, the underlying mechanisms are still largely unclear. This study investigated two prominent theoretical models on suicidal ideation and behavior to examine potential pathways: the Integrative Motivational-Volitional (IMV) model and the Interpersonal Theory of Suicide (IPTS).

METHODS

306 psychiatric inpatients (mean age = 36.9 years, 53.6 % female) admitted to psychiatric hospitals after an acute suicidal crisis (n = 145) or a recent suicide attempt (n = 161) were examined shortly after admission and three follow-up points over 12 months using validated measures of CM, suicidal ideation and behavior, defeat, entrapment, and capability for suicide with its subdimensions fearlessness about death (FAD) and pain tolerance (PT). Serial mediation and moderated moderation analyses were conducted to test the proposed pathways.

RESULTS

Results showed positive associations between all CM subtypes and current suicidal ideation. The relationship between CM and suicidal ideation was indirectly mediated by defeat alone and in combination with entrapment, supporting the IMV model. Contrary to IPTS assumptions, CM did not increase capability for suicide, and there was almost no significant interaction between CM and the subdimensions of capability for suicide (FAD and PT) in moderating the transition from suicidal desire to intent to attempt.

CONCLUSIONS

The study provides support for the IMV model while questioning certain IPTS assumptions regarding the relationship between CM and suicidal ideation and behavior in adulthood.

Further evidence for the association between childhood trauma and suicidal ideation in young individuals: A twin based study

BACKGROUND

Suicide is a major cause of death among youth. Childhood trauma (CT) has emerged as a leading environmental risk factor for suicidal ideation (SI). The present study intends to understand the association between CT and SI in a sample of twins, highlighting the relevance of CT per se, regardless of genetic vulnerability.

METHODS

Data were derived from a general population young twin study, the TwinssCan project (N = 796; mean age = 17.4). Different types of CT (physical, emotional and sexual) were explored with CTQ and SI through SCL-90-R. The discordance within twin-pairs was used to dissect the genetic and CT effects in SI.

RESULTS

Total CT and all subdomains were associated with an increased risk for SI. The within-pair differences analysis in monozygotic and dizygotic twins suggested that part of this association is not attributable to genetic predisposition, which points out the relevance of CT itself upon the increase of SI. This result converged with CT subdomain analyses of physical abuse and neglect.

LIMITATIONS

While within-pair twin analyses control for genetic risk, additional environmental shared and individual characteristics should be controlled for (such as poverty or protective factors). More detailed information on SI would be of great interest to better capture the complexity of this construct.

CONCLUSION

CT appears to be an important environmental risk factor for SI and at least partly independent of Gene-Environment correlation (rGE). This study highlights the importance of including the history of CT in psychiatric evaluations of patients. The burden of the psychosocial environment on SI could be disentangled by further research on environmental risk and protective factors.

Asian Americans' childhood emotional abuse, emotional neglect, and opioid use: Distress intolerance as moderator

Asian Americans are highly underrepresented in opioid use research, despite recent studies demonstrating the presence of opioid use behaviors in Asian Americans and distinct negative outcomes of opioid use among Asian Americans in comparison to White adults. Emotional abuse and emotional neglect are important risk factors that may impact opioid use. Thus, the purpose of this study was to investigate (a) the associations between childhood emotional trauma (emotional abuse and emotional neglect) and opioid use, and (b) the role of distress intolerance as a moderator. 279 Asian American participants completed an online remote survey. Our findings revealed that childhood emotional abuse and emotional neglect were both significantly and positively associated with opioid use. We found that distress intolerance moderated the association between childhood emotional abuse and opioid use such that at low levels of emotional abuse, participants who exhibited greater distress intolerance displayed greater opioid use. These findings indicate that emotional abuse and neglect are specific forms of childhood trauma that are significantly associated with opioid use, perhaps as a maladaptive coping mechanism that capitalizes on the analgesic effects of opioids on the psychological pain from childhood emotional trauma. Additionally, marginalized populations that demonstrate distress intolerance may suffer negative health outcomes such as opioid use.

The pernicious role of stress on intergenerational continuity of psychopathology

Development and Psychopathology has been a premier resource for understanding stressful childhood experiences and the intergenerational continuity of psychopathology. Building on that tradition, we examined the unique and joint influences of maternal stress on children's effortful control (age 7) and externalizing behavior (age 11) as transmitted via genetics, the prenatal environment, and the postnatal environment. The sample included N = 561 adopted children and their biological and adoptive parents. Path models identified a direct effect of biological mother life stress on children's effortful control (β = -.08) and an indirect effect of her life stress on child externalizing behavior via effortful control (β = .52), but no main or indirect effects of biological parent psychopathology, prenatal stress, or adoptive mother adverse childhood experiences (ACES). Adoptive mother ACES amplified the association between biological mother life stress and child effortful control (β = -.08), externalizing behavior (β = 1.41), and the indirect effect via effortful control, strengthening associations when adoptive mothers reported average or high ACES during their own childhoods. Results suggest that novel study designs are needed to enhance the understanding of how life stress gets "under the skin" to affect psychopathology in the offspring of adults who have experienced stress.

Does work modify the relationship between violence and mental health among young people? Evidence from the Violence Against Children Surveys in Uganda, Nigeria and Colombia

Background

Considering the well-established link between experiencing violence in childhood and poor mental health, it is important to understand the role of contextual factors in which young people live, learn, work, and play. Evidence has highlighted the importance of work as a contextual factor in the lives of young people, but it is unclear whether being in work mitigates, entrenches, or exacerbates the association between violence against children and poor mental health.

Methods

This study is based on nationally representative data of males and females aged 13-24 years who completed the Violence Against Children Surveys in Nigeria, Uganda, and Colombia. We used multivariable logistic regression models to explore the association between lifetime violence and past 30-day mental distress, and explored whether working in the past year modified this association. All analyses were age- and sex-stratified and conducted separately in each country.

Results

We found a high prevalence of lifetime violence among young people in all three countries and strong associations between violence and mental distress. In Colombia, there was strong evidence (P-value for interaction = 0.014) that work in the past year (adjusted odds ratio (aOR) = 0.42; 95% confidence interval (CI) = 0.07-2.57) reduced the risk of mental distress among girls who had experienced violence compared to not working in the past year (aOR = 6.12; 95% CI = 2.60-14.41). There was also evidence among boys in Nigeria (P-value for interaction = 0.045), where there was a reduction in risk of mental distress among those not in work in the past year (aOR = 0.99; 95% CI = 0.46-2.13) compared to those in work in the past year (aOR = 2.10; 95% CI = 1.32-3.33). There was also a pattern of effect modification by work in the association between childhood violence and mental health in other population groups, with variation by country, sex, and age groups.

Conclusions

Our findings suggest that work can mitigate, entrench, or exacerbate risk of mental distress among young people who have experienced violence, depending on their age, sex, and country of residence. While additional research is needed to explore these mechanisms, this highlights the importance of work as a contextual factor in the lives of young people and points to the need for safe and secure workplaces and the integration of context-specific interventions into workplaces for young people.

Adverse Childhood Experiences Are Associated with Mental Health Problems Later in Life: An Umbrella Review of Systematic Review and Meta-Analysis

INTRODUCTION

Evidence suggested a link between early adversity and mental health problems. However, it is unclear how much adverse childhood experiences (ACEs) contribute to mental health problems because researchers have produced inconsistent findings. Therefore, the objective of this umbrella review was to combine the contradictory data regarding the effect of ACEs on the development of mental health problems later in life in the global context.

METHODS

PubMed, Embase, Scopus, Web of Sciences, Cochrane Database of Systematic Reviews, Scopus, and Google Scholar which reported the effect of ACEs on the development of mental health problems was searched. The quality of the included studies was assessed using the Assessment of Multiple Systematic Reviews (AMSTAR). A weighted inverse variance random-effects model was applied to find the pooled estimates. The subgroup analysis, heterogeneity, publication bias, and sensitivity analysis were also assessed.

RESULTS

Forty-three SRM with 14,707,614 study participants were included. The pooled effect of ACEs on the development of mental health problems later in life in the global context is found to be (AOR = 1.66 [1.46, 1.87]). Subgroup analysis based on country revealed (AOR = 1.67 [1.23, 2.11]) in UK, (AOR = 0.61 [0.41, 0.81]) in Canada, (AOR = 1.55 [1.40, 1.69]) in Brazil, (AOR = 5.65 [4.12, 7.18]) in Ethiopia, (AOR = 1.92 [1.45, 2.38]) in USA, (AOR = 2.30 [1.89, 2.72]) in Australia, and (AOR = 1.66 [1.46, 1.87]) in Ireland. While subgroup analysis based on types of adverse childhood adverse experience: domestic violence (AOR = 4.13 [1.96, 6.30]), maltreatment (AOR = 1.5 [0.79, 2.21]), physical abuse (AOR = 1.56 [1.43, 1.63]), sexual abuse (AOR = 2.07 [1.63, 2.51]), child abuse (AOR = 5.66 [4.12, 7.18]), parental mental health problem (AOR = 1.73 [1.39, 2.08]), bullying (AOR = 1.99 [1.69, 2.29], neglect (AOR = 2.11 [1.53, 2.69]), and parental divorce (AOR = 1.66 [1.46, 1.87]). Based on the type of mental health problem, the pooled effect size is 1.87 (1.45, 2.30) for depression and 1.67 (1.22, 2.13) for anxiety.

CONCLUSION

This umbrella review revealed that ACE is significantly associated (with 66% increased risk) with anxiety and depression later in life in a global context. This association is most noticeable when one is subjected to domestic violence, maltreatment, physical abuse, sexual abuse, child abuse, parental mental health problems, bullying, neglect, and parental divorce. Childhood periods are a critical window of opportunity for reducing the risk of developing mental illness in the future and for implementing intervention measures. Preventing childhood maltreatment and addressing psychiatric risk factors can prevent psychopathology. Longitudinal studies are needed to optimize healthcare responses to ACEs. Increased awareness and public health interventions are needed to prevent childhood adversity and prevent mental problems among these victims. To optimize healthcare responses to unfavorable outcomes of childhood adversities, longitudinal and intervention research findings, more public health initiatives, and awareness are required.

Eating disorders: etiology, risk factors, and suggestions for prevention

PURPOSE OF REVIEW

The incidence of eating disorders has increased worldwide. This narrative review gives an overview of research on etiology and risk factors of eating disorders published in 2022-2024.

RECENT FINDINGS

Eating disorders arise from a complex set of risk factors. The recent increase in incidence of eating disorders can be linked to root causes that include sociocultural pressure to conform to unrealistic and gendered body ideals, rise in obesogenic environments, and the global COVID-19 pandemic. Recent studies have shown that screen time and social media intensify sociocultural pressure to look a certain way. Individual-specific risk factors also increase the likelihood of onset of eating disorders. These include sports, stressful and traumatic life events, family factors, and psychological factors, including disgust sensitivity, aversive experiences, low self-esteem, perfectionism, neuroticism, obsessive-compulsive and impulsive features, and emotional dysregulation. Preexisting mental health conditions, particularly anxiety, depression, and posttraumatic stress disorder, and neurodevelopmental conditions, such as autism and attention-deficit hyperactive disorder, are also associated with increased eating disorder risk. Genetic and biological factors contribute both to risk and resiliency.

SUMMARY

The risk factors of eating disorders are well established. Future studies should focus on increasing resilience and preventive interventions.

Systematic review and meta-analysis: do best-evidenced trauma-focused interventions for children and young people with PTSD lead to changes in social and interpersonal domains?

Objective: Young people with post-traumatic stress disorder experience difficulties in social and interpersonal domains. We examined whether the best-evidenced treatments of PTSD for children and young people (Trauma-focussed Cognitive Behavioural Therapy or Eye Movement Desensitisation and Reprocessing; aged 5-25) improve social or interpersonal factors in randomised controlled trials, compared to a comparator condition.Method: The review was preregistered on PROSPERO (CRD42023455615; 18th August 2023). Web of Science Core Collection, EMBASE, CINAHL, Pubmed, PsycINFO, Cochrane Central Register of Controlled Trials and PTSDPubs were searched, and data were extracted for social and interpersonal outcomes post treatment. A random effect meta-analysis was conducted to obtain between-group pooled effect size estimates.Results: The search resulted in 792 studies, of which 17 met our inclusion criteria (N = 2498). Our meta-analysis included 13 studies which investigated social skills and functioning, revealing a small but non-significant effect favouring the evidence-based treatment versus comparison (g = .20, 95% CI [-0.03, 0.44], p = .09). We narratively synthesised six studies which reported other social-related outcomes (e.g. perceptions of social support), and four out of six reported improved social domain outcomes for the evidence-based PTSD treatment condition. There was a large amount of heterogeneity, with no evidence that this could be explained by moderators.Conclusion: Few trials report on social and interpersonal outcomes, and where they are reported the evidence is mixed. It may be that trauma-focused therapies for PTSD need to be adapted in some circumstances, so that they address social and interpersonal deficits often seen in children and young people with PTSD.

The lasting effects of childhood trauma on developing psychiatric symptoms: A population-based, large-scale comparison study

Background

Childhood trauma (CT) increases rates of psychiatric disorders and symptoms, however, the lasting effect of CT into adulthood has little exploration using large-scale samples.

Objectives

This study estimated the prevalence of CT in a large sample of Chinese young adults, examining the risk factors of current psychological symptoms among those with CT experiences.

Methods

117,769 college students were divided into CT and non-CT groups. The propensity score matching method balanced the confounding sociodemographic factors between the two groups, compared to 16 self-reported psychiatric disorders (e.g., depression, anxiety, eating disorder, obsessive-compulsive disorder, autism, social anxiety disorder, post-traumatic stress disorder), and seven current psychiatric symptoms. Hierarchical regression employed the significant risk factors of the seven current psychiatric symptoms.

Results

The prevalence of CT among young adults was 28.76% (95% CI: 28.47-29.04%). Youths with CT experiences reported higher psychiatric disorder rates and current symptom scores (P < 0.001). Sociodemographic factors (females, family disharmony, low socioeconomic status, poor relationship with parents, lower father's education level) and lifestyle factors (smoking status, alcohol consumption, lack of exercise) were significantly associated with current psychiatric symptoms.

Results

Public health departments and colleges should develop strategies to promote mental health among those who have experienced CT.

Suicide Attempts during Pregnancy and Postpartum: A Systematic Review and Meta-Analysis

PURPOSE

Suicide attempts (SA) during perinatal period have the potential to adversely affect a woman's health and her developing infant. To date, little is known about perinatal SA and their risk factors. This study aimed to synthetize the evidence on risk factors of SA in pregnant and postpartum women.

METHODS

We systematically reviewed studies retrieved from PubMed/Medline, PsycINFO, and CINAHL, following the PRISMA guidelines for reporting. A meta-analysis was conducted only for risk factors examined in at least three distinct samples.

RESULTS

A total of ten studies were eligible for inclusion. All the studies found significant associations in regression models between perinatal SA and other variables (sociodemographic, clinical factors obstetric, neonatal, and psychosocial). The meta-analysis showed that unmarried women (pooled OR = 1.87, 95% CI = 1.26-2.78), with no higher education (pooled OR = 1.89, 95% CI = 1.31-2.74) and affected by a mood disorder (pooled OR = 11.43, 95% CI = 1.56-83.87) have a higher risk of postpartum SA; women who smoke during pregnancy (pooled OR = 3.87, 95% CI = 1.35-11.11) have a higher risk of SA in pregnancy; and women with previous suicidal behavior(pooled OR = 38.04, 95% CI = 3.36-431.17) have a higher risk of perinatal SA, whether during pregnancy or in the postpartum period. The type of sample, whether community or clinical, is a relevant moderating factor.

CONCLUSION

Our study extends prior reviews about suicidal behaviors in women by studying perinatal suicide attempts independently, as well as it synthesized data on some sociodemographic, clinical, and obstetric/neonatal risk factors. Further studies about specific risk factors for perinatal SA are needed in order to improve early detection and intervention of women at risk.

Influence of at-risk family interactions on the course of psychiatric care in adolescence

Dysparenting, referring to inappropriate parental attitudes, is a vulnerability factor for mental disorders during adolescence and a therapeutic leverage, yet clinicians lack reliable tools to assess it in daily clinical practice. Moreover, the effect of this dysparenting on the amount of psychiatric care remains unclear. The Family and Care study aims to develop the at-risk family interactions and levers (ARFIL) scale, a comprehensive 30-item clinical scale, and to assess in a cross-sectional design, the impact of these at-risk family interactions on the care of adolescents (n = 425) hospitalized in psychiatry and aged 13-19 years old. Factorial analysis shows that the ARFIL scale consists of three main dimensions associated with cohesion/conflicts, love/hostility, and autonomy/control with good psychometric properties. Multivariate regressions show that the ARFIL intensity score predicts the duration of hospital care, regardless of age, gender, medical severity on admission, assessed by the Global Assessment of Functioning scale, the presence of maltreatment and psychiatric diagnoses. Moreover, the ARFIL diversity score (number of items present regardless of their severity) predicts both the number and duration of hospitalizations. At-risk family interactions are a determining dimension of psychiatric adolescent care, and the ARFIL scale could constitute a valuable tool, not only for holistic evaluation and treatment, but also for prevention.

A Scoping Review of Factors Associated With the Mental Health of Young People Who Have "Aged Out" of the Child Welfare System

Young people who grow up in care and then exit care around the age of 18 (care-leavers) are a particularly vulnerable group, at increased risk for mental health problems even relative to other care-experienced groups. Yet, little is understood about the factors underpinning this association. We used scoping review methods to synthesize the quantitative and qualitative literature on factors that are associated with mental health problems for care-leavers. Following rigorous methods, we systematically searched three scientific databases spanning psychology and social care and identified 23 peer-reviewed studies for inclusion. This review highlights the heterogeneity of this research, in terms of methodology and topics investigated. Topics included are as follows: pre-care maltreatment, care-related experiences, psychological factors (emotion regulation), social support, education, and adult functioning (e.g., housing, finances, employment). We found mixed and inconsistent findings across research studies. The strongest evidence-base is around the influence of social support upon the mental health of recent care-leavers, though methodological problems are discussed. The field benefits from several large-scale observational and longitudinal research studies. However, there is an over-reliance upon retrospective reporting, and the use of unvalidated measures is common. It is apparent that there are significant gaps in our current understanding of the mental health of care-leavers, in particular around modifiable factors. We discuss potential directions for future empirical research, both in terms of methodology and factors investigated.

Continuous chains: childhood maltreatment and intimate partner violence victimization among displaced women in a war context

BACKGROUND

Childhood victimization has been associated with long-term psychological effects and an increased risk of being victimized in later life. Previous research has primarily focused on sexual abuse during childhood, and a wide range of consequences have been identified. However, a significant gap remains in our understanding of the complex interaction between different forms of childhood abuse and violence in later life, particularly in the context of broader social stressors such as armed conflict and displacement.

METHODS

This study examines the association between exposure to different types of childhood maltreatment in the context of family and intimate partner violence (IPV) among displaced women living in refugee camps in northern Iraq. Structured interviews were conducted by trained female psychologists with 332 women aged between 20 and 62 years.

RESULTS

Results indicated that over one-third of the participating women reported experiencing at least one occurrence of IPV by their husbands within the past year. In addition, participants reported experiences of different types of maltreatment (physical, emotional, and sexual violence and physical and emotional neglect) perpetrated by family members in their childhood. While all forms of childhood maltreatment showed an association with IPV within the past year, only emotional childhood maltreatment was found to be a significant predictor of IPV in a multivariate analysis.

CONCLUSION

The study highlights the ongoing impact of child maltreatment and its contribution to increased vulnerability to IPV victimization in later life. In addition, this study describes the specific cultural and contextual elements that contribute to IPV in refugee camps.

Psychological maltreatment, meaning-centered coping, psychological flexibility, and suicide cognitions: A moderated mediation model

BACKGROUND

Mental health problems are currently diversifying, increasing the possibility of suicide. Exposure to psychological maltreatment is one of the factors that increases suicidal cognitions. In addition, psychological flexibility and meaning-centered approaches may be effective in coping with suicidal cognitions.

OBJECTIVE

A hypothesized model was tested to examine the relationships among psychological maltreatment, suicidal cognitions, psychological flexibility, and meaning-centered coping.

METHOD

Data were collected from a sample of 652 participants. Mediation and moderation analyses were conducted to examine the mediating and moderating role of psychological flexibility and meaning-centered coping in the relationship between childhood psychological maltreatment and suicide cognitions among Turkish adults.

RESULTS

The results of the study indicated significant negative and positive relationships between psychological maltreatment, suicide cognitions, psychological flexibility, and meaning-centered coping. The findings suggest that psychological flexibility and meaning-centered coping have a serial mediating effect on the relationship between psychological maltreatment and suicide cognitions. Furthermore, according to the study results, psychological flexibility plays a moderating role both between psychological maltreatment and suicidal cognitions and between meaning-centered coping and suicidal cognitions.

CONCLUSIONS

The study suggests that psychological maltreatment can be considered as a risk factor and meaning-centered coping and psychological flexibility as protective factors in suicide prevention studies.

From childhood trauma to alcohol use disorder severity - significance of depressive symptoms and expectations towards analgesic effects of alcohol

AIMS

The objective of the current study was to describe and analyse associations between childhood emotional abuse, severity of depressive symptoms, and analgesic expectations of drinking in individuals with alcohol use disorder (AUD).

METHODS

A total of 240 individuals aged 43.85 ± 11.0 with severe AUD entering an inpatient, abstinence-based, and drug-free treatment program were assessed. The data on AUD severity, depressive symptoms, expectations towards the analgesic effects of alcohol and childhood emotional trauma was collected using questionnaire measures. The PROCESS SPSS macro for serial mediation with bootstrapping was used to test whether current severity of depressive symptoms and expectations towards analgesic effects of alcohol use serially mediated the association between childhood emotional abuse on AUD symptom severity.

RESULTS

There was evidence for two simple mediated effects, whereby the severity of depressive symptoms mediated the association between childhood emotional abuse on AUD symptom severity, and expectations towards analgesic effects of alcohol mediated the association between childhood emotional abuse on AUD symptom severity. There was also evidence to support serial mediation whereby both severity of depressive symptoms and expectations towards analgesic effects of alcohol mediated the association between childhood emotional abuse on AUD symptom severity.

CONCLUSIONS

It might be clinically relevant to address experiences of childhood emotional trauma, as well as individual expectations of analgesic effects of alcohol, in AUD treatment programs.

The impact of childhood trauma on borderline personality organization in a community sample of Greek emerging adults

There is limited research on the role of childhood trauma in personality pathology according to Kernberg's psychodynamic model of internalized object relations. Because childhood trauma reflects the disruptions of these relations, it is expected to predict borderline personality organization, especially at the threshold of adulthood. Therefore, the main aim of this retrospective study was to examine the impact of childhood trauma on borderline personality organization in a community sample of emerging adults. Participants were 543 Greek individuals aged 18-29 (M = 21.45; 58.6 % females; 85.1 % university students). They completed the Greek versions of the Traumatic Antecedents Questionnaire (TAQ) and the Inventory of Personality Organization (IPO), which were tested for their factorial structure, reliability, and measurement invariance across gender, as few empirical data exist on the psychometric properties of these measures. Confirmatory factor analyses showed that the TAQ consisted of four factors, namely positive experiences, abuse, traumatic life events, and family chaos. The five-factor theoretical structure of the IPO, namely primitive defenses, identity diffusion, reality testing, aggression, and moral values, was confirmed. Low to moderate links between childhood trauma and borderline personality organization were found, with stronger links emerging for abuse and family chaos. Structural equation modeling showed that the various forms of childhood trauma across the age periods studied (i.e., 0-6, 7-12, 13-18) significantly and differentially predicted the dimensions of borderline personality organization. The finding that stronger links emerged when trauma occurred in older ages may be attributed to the retrospective method of the study. Gender differences were also found; for example, personality pathology was more likely in men when abuse and traumatic life events occurred in younger ages and abuse was a more important risk factor for personality pathology in women. This study highlights the impact of childhood adversity on personality pathology in emerging adulthood, provides empirical support for Kernberg's psychodynamic model, and has useful implications for trauma-informed early screening, prevention, and intervention regarding personality pathology in young people. Limitations of this study and suggestions for future research are outlined.

Neurological, Metabolic, and Psychopathological Correlates of Lifetime Suicidal Behaviour in Major Depressive Disorder without Current Suicide Ideation

INTRODUCTION

Suicidal behaviour (SB) has a complex aetiology. Although suicidal ideation (SI) is considered the most important risk factor for future attempts, many people who engage in SB do not report it.

METHODS

We investigated neurological, metabolic, and psychopathological correlates of lifetime SB in two independent groups of patients with major depression (sample 1: n = 230; age: 18-65 years; sample 2: n = 258; age >60 years) who did not report SI during an index episode.

RESULTS

Among adults (sample 1), SB was reported by 141 subjects (58.7%) and severe SB by 33 (15%). After controlling for interactions, four risk factors for SB emerged: male gender (OR 2.55; 95% CI: 1.06-6.12), negative self-perception (OR 1.76; 95% CI: 1.08-2.87), subthreshold hypomania (OR 4.50; 95% CI: 1.57-12.85), and sexual abuse (OR 3.09; 95% CI: 1.28-7.48). The presence of at least two of these factors had the best accuracy in predicting SB: sensitivity = 57.6% (39.2-74.5); specificity = 75.1% (68.5-82.0); PPV = 27.9% (20.9-37.2); NPV = 91.4% (87.6-94.1). In older patients (sample 2), 23 subjects (9%) reported previous suicide attempts, which were characterized by earlier onset (25 years: OR 0.95: 0.92-0.98), impaired verbal performance (verbal fluency: OR 0.95: 0.89-0.99), higher HDL cholesterol levels (OR 1.04: 1.00-1.07) and more dyskinesias (OR 2.86: 1.22-6.70).

CONCLUSION

Our findings suggest that SB is common in major depressive disorder, even when SI is not reported. In these individuals it is feasible and recommended to investigate both psychiatric and organic risk factors. The predictive power of models excluding SI is comparable to that of models including SI.

Relations between childhood psychological maltreatment and mental health dimensions within a higher-order model

Background

Experiences of childhood psychological maltreatment have been found to be associated with various mental health outcomes, and this association persists into adulthood.

Objective

This study investigated whether some types of psychological maltreatment are more harmful than others; whether the harms associated with different types of psychological maltreatment are generalized or specific to particular domains of psychopathology; and whether the associations vary by gender.

Method

Participants (N = 544, 63.9 % mother as primary caregiver) were Chinese adults from various regions in China. Participants completed measures of childhood psychological maltreatment experiences perpetrated by their primary caregiver and the mental health outcomes of depression, anxiety, anger, physical aggression, and hostility. The data were analyzed in a hierarchical model in which depression and anxiety were defined as indicators of an internalizing factor, while anger, physical aggression, and hostility were defined as indicators of an externalizing factor. Internalizing and externalizing then defined a higher-order general psychopathology factor. The results suggested equivalent harms of psychological abuse and psychological neglect. Further, the associations between psychological maltreatment and mental health were not unique to specific symptom domains but showed broadband associations with general psychopathology.

Results

These findings suggest that trans-diagnostic interventions may be the most effective approach for addressing the mental health impacts of psychological maltreatment.

Conclusion

Childhood psychological maltreatment may pose a broadband risk for any and all forms of psychopathology.

Molecular Changes Associated with Suicide

Suicide is a serious global public health problem, with a worrying recent increase in suicide rates in both adolescent and adult populations. However, it is essential to recognize that suicide is preventable. A myriad of factors contributes to an individual's vulnerability to suicide. These factors include various potential causes, from psychiatric disorders to genetic and epigenetic alterations. These changes can induce dysfunctions in crucial systems such as the serotonergic, cannabinoid, and hypothalamic-pituitary-adrenal axes. In addition, early life experiences of abuse can profoundly impact an individual's ability to cope with stress, ultimately leading to changes in the inflammatory system, which is a significant risk factor for suicidal behavior. Thus, it is clear that suicidal behavior may result from a confluence of multiple factors. This review examines the primary risk factors associated with suicidal behavior, including psychiatric disorders, early life adversities, and epigenetic modifications. Our goal is to elucidate the molecular changes at the genetic, epigenetic, and molecular levels in the brains of individuals who have taken their own lives and in the plasma and peripheral mononuclear cells of suicide attempters and how these changes may serve as predisposing factors for suicidal tendencies.

Latent profiles of childhood psychological maltreatment and their links to adult mental health in China and the UK

BACKGROUND

Though links between childhood maltreatment and mental health have been established, little known about how specific types of childhood maltreatment tend to cluster and how the resulting patterns of exposure impact mental health outcomes.

METHOD

The current study used latent profile analyses in Chinese (N = 544) and UK (N = 589) samples to identify childhood psychological maltreatment profiles (i.e., profiles of psychological abuse, psychological neglect, and psychological non-support) in different country contexts, and their associations with a range of mental health (i.e., depression, anxiety, anger, physical aggression, verbal aggression, and hostility), and broader well-being (i.e., self-esteem) outcomes. Unadjusted as well as analyses adjusted for adverse childhood experiences (ACEs) were conducted.

RESULTS

Four profiles were identified in both samples, but their nature differed between the Chinese sample ("Psychological Non-support", "Low-Maltreated", "High-Maltreated", and "Severe-Maltreated") and the UK sample ("Low-Maltreated", "Moderate-Maltreated", "High-Maltreated", and "Severe-Maltreated"). Individuals in the "Psychological Non-support" in China and "Low-Maltreated" class in the UK displayed better mental health outcomes-lower levels of depression, anxiety, and aggression, and higher self-esteem. In contrast, individuals in the "Severe-Maltreated" profiles in both the Chinese and UK samples displayed poorer mental health outcomes-higher depression, anxiety, and aggression, and lower self-esteem. Interventions and prevention efforts are needed for individuals categorized in profiles affected by psychological maltreatment.

CONCLUSION

This study highlights the importance of using targeted intervention or prevention to prevent psychological maltreatment, as well as improve mental health outcomes in individuals who have experienced psychological maltreatment.
