Associations between suicidal behavior and childhood abuse and neglect: A meta-analysis

Specific effects of cumulative childhood trauma on suicidality among youths

BACKGROUND

Suicidality was very high among individuals who suffered from childhood trauma. The distribution of cumulative childhood trauma among youths remains unclear, as well as the specific effects of cumulative childhood trauma on suicidality. This study attempted to explore the distribution of cumulative childhood trauma and examine the specific effects of cumulative childhood trauma on suicidality.

METHODS

A cross-sectional design was employed in this study, with 117,769 college students recruited from 63 universities in Jilin Province, China. All variables were measured by corresponding self-report questionnaires. The Venn diagram was used to represent the distribution of single and cumulative childhood trauma. ANOVA and chi-square tests were conducted to identify the high-risk suicide groups. Multiple linear regression analysis was performed to examine risk factors for suicidality for overlapping subtypes.

RESULTS

27,671 (23.5%) participants reported suffering from childhood trauma, of which 49.5% were male (Mage = 19.59, SD = 1.76). The "physical neglect" group accounted for the largest proportion (31.5%). Suicidality was the highest in the "overlap of childhood neglect, emotional abuse, and physical abuse" group (2.0%). Depression, obsessive-compulsive disorder, and post-traumatic stress disorder were common risk factors for suicidality.

LIMITATIONS

This study was limited by cross-sectional studies and self-report bias.

CONCLUSIONS

The childhood trauma subtype group with the largest proportion was not necessarily the highest suicidality. Both the largest group and the highest-risk suicide group require special attention to their respective risk factors.

Self-reported suicidal ideation among individuals with first episode psychosis and healthy controls: Findings from the international multicentre EU-GEI study

INTRODUCTION

Suicidal ideation is common among individuals with first episode psychosis (FEP), with prevalence estimates up to 56.5 %. Despite its high prevalence, relatively little is known about how sociodemographic, clinical and/or developmental characteristics contribute to the experience of suicidal ideation in individuals with FEP.

METHODS

In this cross-sectional study (FEP n = 551 and controls n = 857), univariate logistic regression analyses were performed to study the associations of sociodemographic, clinical, and developmental factors with suicidal ideation in individuals with FEP as well as controls. Suicidal ideation was assessed using the Community Assessment of Psychic Experiences (CAPE). In addition, multivariate logistic regression analyses were conducted based on a stepwise approach.

RESULTS

In FEP, only depressive symptoms remained significantly associated with suicidal ideation when all correlates were integrated into one model. In the multivariate model in controls, depressive symptoms, positive symptoms, and traumatic childhood experiences were significantly associated with suicidal ideation.

CONCLUSIONS

This study showed that depressive symptoms are an important factor relating to suicidal ideation in individuals with FEP, over and above other clinical, sociodemographic, and developmental factors. This underscores the relevance of screening for suicidal ideation in individuals with FEP, and highlights the need for a better understanding of the diagnostic uncertainty and course of mood symptoms in early psychosis.

LIMITATIONS

Cross-sectional study design, self-reported questionnaires.

Early life adversities, psychopathologies and novel pharmacological strategies

Exposure to adversities during early life stages (early life adversities - ELA), ranging from pregnancy to adolescence, represents a major risk factor for the vulnerability to mental disorders. Hence, it is important to understand the molecular and functional underpinning of such relationship, in order to develop strategies aimed at reducing the psychopathologic burden associated with ELA, which may eventually lead to a significant improvement in clinical practice. In this review, we will initially recapitulate clinical and preclinical evidence supporting the link between ELA and psychopathology and we will primarily discuss the main biological mechanisms that have been described as potential mediators of the effects of ELA on the psychopathologic risk, including the role for genetic factors as well as sex differences. The knowledge emerging from these studies may be instrumental for the development of novel therapeutic strategies aimed not only at correcting the deficits that emerge from ELA exposure, but also in preventing the manifestation of a full-blown psychopathologic condition. With this respect, we will specifically focus on adolescence as a key time frame for disease onset as well as for early therapeutic intervention. We believe that incorporating clinical and preclinical research data in the context of early life adversities can be instrumental to elucidate the mechanisms contributing to the risk for psychopathology or that may promote resilience. This will ultimately allow the identification of 'at risk' individuals who may benefit from specific forms of interventions that, by interfering with disease trajectories, could result in more benign clinical outcomes.

Childhood maltreatment and suicide attempts in major depression and bipolar disorders in South Korea: A prospective nationwide cohort study

BACKGROUND

Childhood maltreatment (CM) is prevalent among patients with mood disorders and considered an important risk factor for suicide in the general population. Despite mood disorders being implicated in up to 60 % of completed suicides, the predictive role of CM on suicide attempt (SA) among early mood disorder patients remains poorly understood.

METHODS

We enrolled 480 participants diagnosed with early-onset major depressive disorder (MDD), bipolar I disorder (BD I), and bipolar II disorder (BD II). Over an average of 60 weeks, participants underwent follow-up assessments at 12-week intervals. Using multivariate logistic regression, we examined the association between CM and SA history at baseline. Further, the Cox proportional hazard model assessed the predictive role of childhood maltreatment in SA during follow-up.

RESULTS

At baseline, 38 % of the total participants reported SA history, with a follow-up prevalence of 10 %. Childhood maltreatment was significantly associated with past SAs and was a robust predictor of future SA, adjusting for relevant clinical risk factors. Emotional abuse and sexual abuse related to SA history, and physical abuse increased future SA risk.

LIMITATIONS

Potential biases in reporting SA and childhood maltreatment, along with unexplored factors such as additional environmental and familial risks, may affect the study's findings.

CONCLUSIONS

Childhood maltreatment emerged as a robust predictor of SA among early-onset mood disorder patients. Systematic evaluation of CM early in the clinical process may be crucial for effective risk management. Additionally, our findings highlight the importance of implementing proactive interventions for CM to prevent the onset of adverse psychological trajectories.

Bisphenol AF exposure synergistically increases the risk for suicidality among early adolescents with child maltreatment: A prospective cohort study

BACKGROUND

Child maltreatment (CM) is correlated with suicidality risk among adolescents. Additionally, exposure to bisphenol AF (BPAF) may increase this risk. However, the combined effect of CM and BPAF exposure remains unknown and should be further investigated.

METHODS

In this study, 1,475 early adolescents (mean age = 12.48 years) from the Chinese Early Adolescents Cohort were enrolled. Data were collected at three time points with an interval of 12 months between 2019 and 2021. Participants' history of CM and suicidality (including suicidal ideation and suicidal attempts) were evaluated using a self-report questionnaire. Blood samples were obtained from participants to measure serum BPAF concentrations at baseline. Group-based trajectory modeling was employed to identify different developmental trajectories of suicidality across the three waves. After adjusting for potential confounders, the association between CM and BPAF exposure on suicidal ideation and suicidal attempts was assessed using logistic regression and Poisson regression analyses.

RESULTS

Participants with CM were associated with a risk of one- and two-year incident suicidality (all ps < 0.05), and BPAF levels were positively associated with two-year incident suicidal ideation (adjusted OR = 1.68, 95% CI: 1.13-2.50). Additionally, middle and high levels of BPAF exposure synergistically increase the risk for one- and two-year incident suicidal ideation among participants with CM (adjusted ORs = 2.00-3.83). Similarly, participants exposed to high-level BPAF as well as CM were at a greater risk of one- and two-year incident suicidal attempts than those with low-level BPAF exposure and no CM (adjusted incidence rate ratio [IRRs] = 2.82-4.34). Moreover, compared with participants with a low developmental trajectory of suicidality across the three waves, high BPAF exposure exhibited a significant synergistic effect on participants with CM in the persistently high suicidal ideation trajectory and the increasing suicidal attempts trajectory (all ps < 0.05). Sex subgroup analysis revealed that females were more susceptible to the synergistic effect of BPAF and CM exposure on suicidality than males.

CONCLUSIONS

Environmental factors and the psychological status of individuals may synergistically increase their susceptibility to suicidality. These results offer novel insights into enhancing our understanding of suicidality among adolescents.

Association between childhood maltreatment and suicidal ideation among Chinese patients with chronic schizophrenia: the mediating role of insomnia

BACKGROUND

Childhood maltreatment is a well-established transdiagnostic risk factor for suicidal ideation; however, previous studies on their association in schizophrenia have produced highly varied results. Moreover, the mechanism linking childhood maltreatment and suicide ideation remains unclear in schizophrenia.

AIMS

This cross-sectional study aimed to investigate the association between childhood maltreatment and suicide ideation in people with schizophrenia and tested whether insomnia mediated this relationship.

METHOD

Positive and Negative Syndrome Scale (PANSS), Insomnia Severity Index (ISI), Childhood Trauma Questionnaire - Short Form and Beck Suicidal Ideation Inventory were employed. Logistic regression and mediation analysis were performed.

RESULTS

(a) The prevalence of suicide ideation, insomnia, sexual abuse, emotional neglect, emotional abuse, physical abuse and physical neglect was 10% (n = 61), 18% (n = 111), 11% (n = 68), 25% (n = 153), 6.3% (n = 39), 17% (n = 106) and 39% (n = 239), respectively. In all, 52% (n = 320) reported childhood maltreatment; (b) patients with suicide ideation demonstrated higher insomnia and childhood maltreatment. PANSS depression factor, ISI, lifetime suicidal attempts and emotional abuse were independently associated with suicide ideation; (c) insomnia partially mediated the effects of emotional abuse and emotional neglect on suicide ideation, and insomnia completely mediated the effects of physical neglect and physical abuse on suicide ideation.

CONCLUSION

Our study calls for formal assessments for childhood maltreatment and insomnia in schizophrenia, which might help identify suicide ideation early. In addition, interventions targeting insomnia might help reduce suicide ideation among people with schizophrenia who experience childhood maltreatment.

Long-term consequences of childhood emotional abuse in mothers on parental load and child mental health

BACKGROUND

Childhood emotional maltreatment can be associated with long-term consequences on mental health. In addition, transgenerational transmission of adverse childhood experiences to the next generation can occur and thus have an impact on the mental health of one's own children.

OBJECTIVE

The purpose of this study was to examine the role of stress on the association between childhood emotional maltreatment and parental load what is referred to in this study as limitations in parental functioning that affect the resources available to parents to cope with the demands of raising, caring for, and providing for their child. Furthermore the effect of parental load on the mental health of one's own children will be examined.

PARTICIPANTS AND SETTING

N = 237 mother-child dyads (age mother M = 33.76, SD = 4.07 years; age child M = 11.91 months, SD = 0.89 months) from a longitudinal cohort study were examined at two different measuring points.

METHODS

Emotional abuse, perceived stress, parental load and child mental health were assessed using self and external report questionnaires.

RESULTS

The calculation of a mediation showed that the association of emotional abuse and parental load was completely mediated by perceived stress (indirect effect ab = 0.44, 95 %-CI[0.17, 0.78]). In addition, effects of parental load on the child's mental health (β = 0.13, 95%CI [0.07;0.20]), mainly hyperactivity (β = 0.06, 95%CI [0.03;0.11]) and prosocial behavior (β = -0.04, 95%CI [-0.07; -0.01]), were evident.

CONCLUSIONS

The results of this study provide evidence that the mental health of children can be influenced in the long term by increased parental load.

The mediating role of reflective functioning in the association between childhood trauma and suicide attempt

BACKGROUND

Childhood trauma is intimately related with suicidal behaviour. Patients who have suffered childhood trauma develop impaired Reflective Functioning (RF), which refers to the capacity to understand ourselves and others in terms of intentional mental states. An improvement in RF has been associated with a reduction in suicidal attempts, but the mediating role of RF between childhood trauma and suicidal behaviour has not been addressed so far.

OBJECTIVE

We aim to examine the potential mediating effect of RF among childhood trauma and suicide attempts.

METHOD

We included 748 patients who had attempted suicide at least once. They were asked to complete the Reflective Functioning Questionnaire (RFQ-8), the Columbia-Suicide Severity Rating scale (CSSRS), and the Childhood Trauma Questionnaire-Short Form (CTQ-SF). We conducted linear regressions by simple mediating model to examine the role of RF in the indirect association between childhood trauma and the number of suicide attempts.

RESULTS

Our results show significant indirect effects through hypo and hypermentalizing between Emotional Abuse (EA) and Sexual Abuse (SA) in childhood and the number of suicide attempts in lifetime. These results indicate that ineffective RF significantly mediates the association between childhood trauma and suicidality.

CONCLUSION

This is the first study supporting the mediational role of RF in the relationship between EA and SA, and the number of suicide attempt in lifetime. These findings have important implications for reducing suicide rates and preventing future re-attempts. Further studies analysing this mediating role and focusing efforts on increasing RF-based interventions are required.

Childhood Maltreatment and Suicidal Thoughts and Behaviors in Young Adults

Background: Childhood maltreatment strongly predicts suicidality in young adulthood, which is increasingly common among Latina/o and Asian Americans. However, greater attention to modifiable explanatory factors is needed, particularly in ethnically minoritized populations. Aims: The current study evaluated whether the association between childhood maltreatment and suicidality may be accounted for by emotion regulation difficulties among a sample of young adults attending a large, minority-serving state university. Methods: Young adults (n = 853 participants; Mage = 22.43 years; 76.2% female) completed validated measures of suicidality, childhood maltreatment, depression, and emotion regulation difficulties. A multiple indirect effect analysis was conducted in a structural equation modeling framework. Results: Greater childhood maltreatment was associated with significantly greater emotion regulation difficulties across all six types and greater endorsement of overall suicidality. An indirect effect was found for limited access to regulation strategies only. Unexpectedly, lack of emotional awareness was associated with lower levels of ideation/attempts or threats of engaging in suicidal behavior. Limitations: The study was cross-sectional, precluding conclusions regarding causality. Conclusions: The findings suggest that, for individuals who have experienced childhood maltreatment, it is particularly important to address deficits in access to emotion regulation strategies to reduce the risk of suicidal ideation and behavior.

Childhood adversities and suicidal behavior in the general population. The cross-sectional PEGASUS-Murcia Project

INTRODUCTION

The aim of the present study is to estimate the lifetime prevalence of suicidal ideation, plans, and attempts in a regional representative sample and the association of these outcomes with sociodemographic factors, prior mental disorders, and childhood adversities.

MATERIAL AND METHODS

The PEGASUS-Murcia project is a cross-sectional survey of a representative sample of adults in Murcia that is part of the WHO World Mental Health Survey Initiative. The Composite International Diagnostic Interview (CIDI 3.0) was administered face-to-face to 2621 participants (67.4% response rate). The main outcomes were suicidal ideation, plans, and attempts. Lifetime prevalence, age of onset, and risk factors (sociodemographic variables, mental disorders, and childhood adversities) were examined using multiple discrete-time survival models.

RESULTS

Lifetime prevalence of suicidal ideation, plans and attempts were 8.0% (standard error, SE: 1.1), 2.1% (SE: 0.3), and 1.2% (SE: 1.1), respectively. Prevalence of any childhood adversities was 22.1% (SE: 1.3) in the total sample and, even higher, among those with suicide related outcomes (ranging between 36.8% and 53.7%). Female sex, younger age, prior (to onset of the outcome) lifetime prevalence of mood disorders, number of mental disorders, and exposure to childhood adversity were associated with significantly increased odds of suicidal ideation and plans.

CONCLUSIONS

Lifetime prevalence estimates of suicidality are similar to those in community epidemiological surveys. Childhood adversities and mental disorders, especially mood disorders, are important risk factors for suicidality. Early detection of these adversities and disorders should be targeted in suicide prevention programs.

Child maltreatment among victims of violent death: an analysis of national violent death reporting system data, 2014-2018

BACKGROUND

Limited information is known about the impact of childhood maltreatment on lifetime risk of violent death. This study aimed to compare manner of death, demographics, age at time of death, and the presence of a mental health or substance use disorder among decedents of violent deaths with a history of child maltreatment to those without.

METHODS

This cross-sectional study compared characteristics of pediatric and adult violent deaths with and without a history of child maltreatment that were captured in the National Violent Death Reporting System from 2014 through 2018.

RESULTS

Decedents who were male, multiracial, and had adulthood substance or mental health disorders were more likely to have a history of maltreatment. All-age decedents with a history of maltreatment were more likely to die by homicide. Adult decedents with a history of maltreatment were more likely to die by suicide. Maltreated decedents died significantly younger than non-maltreated decedents.

CONCLUSIONS

Among victims of violent deaths, an identified history of child maltreatment was associated with increased risk of homicide across the lifespan, adult suicide, and earlier death. A history of child maltreatment was also associated with mental health and substance use disorders, which may reflect one of the pathways through which the child maltreatment-to-death association functions.

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.

The effect of childhood trauma on suicide risk: the chain mediating effects of resilience and mental distress

BACKGROUND

Suicide is the fourth leading cause of death among young people aged 15-29 years. A large number of studies have found that mental disorder in adulthood is closely related to childhood trauma, and the relationship between childhood trauma and suicide risk is influenced by resilience and mental distress. This study aimed to explore the effects of childhood trauma on suicide risk among young people and the potential roles of resilience and mental distress in the relationship between childhood trauma on suicide risk.

METHODS

A cross-sectional survey was conducted among 742 young adults who were in graduate school stage from multiple provinces and cities in China. The Childhood Trauma Questionnaire (CTQ-Short Form), Connor-Davison Resilience Scale (CD-RISC) and Suicide Behavior Questionnaire-Revised (SBQ-R) were used to measure young adults' childhood trauma, resilience and suicide risk, respectively. 9-items Patient Health Questionnaire (PHQ-9) and 7-items self-report Generalized Anxiety Disorder Scale (GAD-7) were used together to measure mental distress. Correlation analysis was performed to explore the initial relationships among the main variables. Structural equation modeling (SEM) was conducted to examine the chain mediating effects of resilience and mental distress in the relationship between childhood trauma and suicide risk.

RESULTS

The structural equation modeling produced goodness of fit indices (χ2 /df = 3.668, p < 0.001, RMSEA = 0.060, NFI = 0.959, CFI = 0.969, GFI = 0.969, TLI = 0.955). Childhood trauma significantly predicted suicide risk (β = 0.232, p < 0.001) and mental distress (β = 0.181, p < 0.001), which had negative effect on resilience (β = -0.233, p < 0.001). Resilience negatively affected mental distress (β = -0.483, p < 0.001) and suicide risk (β = -0.142, p = 0.001), while mental distress positively associated with suicide risk (β = 0.219, p < 0.001).

CONCLUSION

The current study revealed that resilience and mental distress played chain-mediating roles in the relationship between childhood trauma and suicide risk. This suggests that we should view the suicide risk of graduate students from a comprehensive perspective.

Risk factors for suicidality across psychosis vulnerability spectrum

BACKGROUND

Suicide is a leading cause of death in individuals with psychotic disorders. Risk factors for suicidality across the psychosis vulnerability spectrum are insufficiently known.

METHODS

For patients (n = 830), siblings (n = 664) and controls (n = 444), suicidality was assessed by the use of a clinical interview. Multilevel modelling was used to investigate risk factors of suicidality. Lastly, risk factor × familial risk interaction effects were examined.

RESULTS

Multivariable models revealed a significant relation between suicidality and depressive symptoms across all three groups, and childhood trauma in patients and siblings. The association between suicidality and psychotic-like experiences is more pronounced in siblings compared to controls.

CONCLUSION

Across the psychosis vulnerability spectrum, depressive symptoms and childhood trauma have been associated with suicidality. Clinicians should pay attention to suicidality in individuals at high familial risk for psychosis with psychotic-like experiences.

The interactive effects of AS and trauma exposure on suicide capability and suicide risk

BACKGROUND

Trauma exposure has been linked with heightened suicide risk purportedly through habituation to threatening stimuli, thereby reducing fear of suicide. However, no research has examined variables that may influence this process. Anxiety sensitivity (AS) is one cognitive-affective factor that may strengthen the relationship between trauma exposure and reduced fear of suicide by amplifying traumatic reactivity. The present study evaluated this by examining the interaction of AS and trauma exposure type (e.g., direct vs. witnessed) predicting fear of suicide and self-reported suicide risk.

METHODS

Participants (n = 124) were recruited for a long-term (∼3-4 years) follow-up after participation in a clinical trial targeting suicide risk factors and were asked to complete self-report measures of trauma history, AS, fear of suicide, and suicide risk.

RESULTS

Significant interactions emerged such that a greater number of direct traumasexperienced predicted lower fear of suicide and greater suicide risk among those with greater AS. The interactive effect of witnessed traumas and AS predicting suicidality was insignificant. Results remained even after including relevant covariates.

DISCUSSION

The current findings suggest that AS augments the effects of repeated trauma exposure on fear of suicide and suicide risk. It is plausible these painful and provocative events are more potent among those with high AS due to the amplification of traumatic affective responses, though future research examining the longitudinal relations is needed to confirm this process.

Interpersonal Well-Being and Suicidal Outcomes in a Nationally Representative Study of Adolescents: A Translational Study

Adolescent suicide continues to rise despite burgeoning research on interpersonal risk for suicide. This may reflect challenges in applying developmental psychopathology research into clinical settings. In response, the present study used a translational analytic plan to examine indices of social well-being most accurate and statistically fair for indexing adolescent suicide. Data from the National Comorbidity Survey Replication Adolescent Supplement were used. Adolescents aged 13-17 (N = 9,900) completed surveys on traumatic events, current relationships, and suicidal thoughts and attempts. Both frequentist (e.g., receiver operating characteristics) and Bayesian (e.g., Diagnostic Likelihood Ratios; DLRs) techniques provided insight into classification, calibration, and statistical fairness. Final algorithms were compared to a machine learning-informed algorithm. Overall, parental care and family cohesion best classified suicidal ideation, while these indices and school engagement best classified attempts. Multi-indicator algorithms suggested adolescents at high risk across these indices were approximately 3-times more likely to engage in ideation (DLR = 3.26) and 5-times more likely to engage in attempts (DLR = 4.53). Although equitable for attempts, models for ideation underperformed in non-White adolescents. Supplemental, machine learning-informed algorithms performed similarly, suggesting non-linear and interactive effects did not improve model performance. Future directions for interpersonal theories for suicide are discussed and clinical implications for suicide screening are demonstrated.

The relationship between child maltreatment and social anxiety: A meta-analysis

BACKGROUND

Globally, child maltreatment has become a serious problem, affecting individuals' physical and mental health. This meta-analysis aimed to explore the association between child maltreatment and social anxiety.

METHODS

MEDLINE, PsycINFO, EMBASE, Scopus, and Web of Science were searched for articles published by October 2021. Newcastle-Ottawa Quality Assessment Scale (NOS) was used to evaluate the quality of studies. Maltreatment type, sample setting, age, country and measurement instruments were analyzed as moderators.

RESULTS

Twenty-nine studies met the inclusion criteria. Child maltreatment was positively correlated with social anxiety (r = 0.201, 95 % CI [0.171, 0.230]). The moderating effect of maltreatment subtypes was significant whether divided into three types (Q_b = 12.152, p = .002), or five types (Q_b = 11.574, p = .021). Specifically, emotional maltreatment (r = 0.251, 95 % CI [0.201, 0.298]) had a stronger relationship with social anxiety than physical (r = 0.138, 95 % CI [0.085, 0.191]; Q_b = 9.312, p = .002) and sexual maltreatment (r = 0.153, 95 % CI [0.108, 0.197]; Q_b = 9.197, p = .002). However, there was no significant difference in the effect size between physical and sexual maltreatment (Q_b = 0.096, p = .757). Other variables (age, sample setting and country) were not significant moderators.

LIMITATIONS

Only twenty-nine studies were included, and there was high heterogeneity among the studies, the interpretation of the results should be cautious.

CONCLUSIONS

This meta-analysis confirmed the relationship between child maltreatment and social anxiety, especially highlight the harmfulness of emotional maltreatment.

COVID-19 impacts and adolescent suicide: The mediating roles of child abuse and mental health conditions

BACKGROUND

Considerable research has established the harmful impacts of the COVID-19 pandemic on children's and adolescents' health and well-being. However, the literature has been constrained by studies using less representative samples, hindering the generalization of the findings.

OBJECTIVE

This study aimed to investigate the associations of employment disruption and school closures during the pandemic with suicidal ideation and behavior in children and adolescents-and to consider the potential mediating effects of child psychological and physical abuse and subsequent mental health conditions.

PARTICIPANTS AND SETTING

This study used the Adolescent Behaviors and Experiences data (n = 4692) - a nationally representative survey administered by the CDC of the United States from January to June 2021.

METHODS

Logistic regression models were conducted to investigate the associations. A series of multiple mediation models were performed.

RESULTS

School closures directly reduced child psychological and physical abuse and suicidal ideation and behavior. Employment disruption did not directly predict suicidal ideation and behavior but primarily through child abuse. Mental health's mediation role was significant in the associations between child psychological abuse and suicidal ideation and behavior, but no evidence suggested the same mediating pattern for the physical abuse-suicidal ideation and behavior relationship. Within the covariates, sexual orientation was the most consistent and highest risk factor.

CONCLUSIONS

This study contributes to current knowledge on disaster impact, child abuse, and suicidal ideation and behavior, and it can also provide policy and intervention awareness for social workers.

The prevalence of childhood sexual experiences and intimate partner violence among transgender women in China: Risk factors for lifetime suicidal ideation

Objective

Several studies highlighted childhood sexual experiences (CSEs) and intimate partner violence (IPV) as risk factors that affected lifetime suicidal ideation. TW had higher rates of CSEs and IPV than cisgender people. The aim of this study was to comprehensively assess the prevalence of CSEs and IPV among TW and their association with lifetime suicidal ideation.

Methods

A cross-sectional survey was conducted among 247 TW in Shenyang and Kunming, China, from April to September 2018. CSEs, IPV, and lifetime suicidal ideation were assessed. Logistic regression models were used to examine the association between self-reported CSEs under 18 years of age, IPV in adulthood, and lifetime suicidal ideation.

Results

In the study, 14.2% (35/247) of the sample participants reported CSEs under 18 years of age; 44.9% (111/247) reported experiencing IPV in adulthood, including 18.6% (44/247) of physical IPV, 27.1% (67/247) of trans-specific identity IPV, 31.6% (78/247) of verbal IPV, and 19.4% (48/247) of sexual IPV; and 26.3% (65/247) had thought about attempting suicide at least one time. CSEs and any form of IPV were significantly associated with suicidal ideation in this sample population. A final stepwise multivariate logistic regression model found that both physical and verbal IPVs were significantly associated with suicidal ideation when controlling for other factors (ORm₁ = 2.58, 95% confidence interval (CI) = 1.163-5.724; ORm₂ = 2.72, 95% CI = 1.334-5.547).

Conclusions

The findings highlight the effects of CSEs and IPV among TW and suggest the need for research on suicide in the future. Suicide prevention efforts for this invisible and vulnerable population should focus on those with physical and verbal IPV.

Childhood Abuse and Neglect, Exposure to Domestic Violence and Sibling Violence: Profiles and Associations With Sociodemographic Variables and Mental Health Indicators

Research indicates substantial overlap between child abuse and neglect (CAN), exposure to domestic violence and sibling abuse, with multiple victimisation experiences conferring greater risk for adverse mental health outcomes than does exposure to a single subtype. The application of latent class analysis (LCA) to child maltreatment has gained momentum, but it remains the case that few studies have incorporated a comprehensive range of subtypes, meaning that real-life patterns in victimisation experiences cannot be accurately modelled. Based on self-report data from an ethnically diverse sample (N = 2813) of 10-17 year olds in the United Kingdom, the current study used LCA to model constellations among nine types of maltreatment in the home (physical, emotional and sexual abuse; physical and emotional neglect; exposure to physical and verbal domestic violence, or a drug-related threat; and sibling violence). A four-class solution comprising of a low victimisation class (59.3% of participants), an emotional abuse and neglect class (19.0%), a high verbal domestic violence class (10.5%) and a maltreatment and domestic violence class (11.2%) provided the best fit for the data. Associations with sociodemographic variables were examined, revealing differences in the composition of the classes. Compared to the low victimisation class, participants in the verbal domestic violence class, emotional abuse and neglect class and especially the maltreatment and domestic violence class, reported higher symptoms of anxiety and depression and an increased likelihood of non-suicidal self-injury, suicide ideation and suicide attempt. The findings carry important implications for understanding patterns of child maltreatment, and the implications for preventative strategies and support services are discussed.

Childhood maltreatment influences suicidal behavior: Rumination mediates and regulatory emotional self-efficacy moderates

To investigate the mediating role of rumination in the association between childhood maltreatment and suicidal behavior, and the moderating role of regulatory emotional self-efficacy, university students (N = 1,458) from 5 universities in China completed questionnaires in classrooms. Path analyses showed emotional maltreatment had the greatest positive association with suicidal behavior and rumination compared with other types of childhood maltreatment. Rumination partly mediated the relationship between childhood maltreatment and suicidal behavior. High regulatory emotional self-efficacy moderated the relation between ruminating childhood maltreatment and suicidal behavior.

A phenomenological exploration of work-related post-traumatic growth among high-functioning adults maltreated as children

Introduction

Childhood maltreatment is a highly prevalent traumatic experience, and its adverse psychological and behavioral consequences are well-documented. Notwithstanding these adverse outcomes, many individuals who suffered from traumatic experiences report post-traumatic growth, i.e., transformative positive changes resulting from their struggle to cope. Post-traumatic growth has been extensively explored among adult survivors of childhood maltreatment, with findings indicating both the previously recognized domains (personal strength, relating to others, appreciation of life, openness to new possibilities, and spiritual change) as well as abuse-specific domains of growth (e.g., increased ability to protect themselves from abuse). However, little attention has been given to vocational aspects of post-traumatic growth among survivors, despite the central role and importance of work in adulthood. Exploration of post-traumatic growth at work has focused on certain vocational traumatic experiences, such as those which occur in the military, or through secondary trauma. This exploratory qualitative study focuses on the question: What is the lived experience of work-related post-traumatic growth among high-functioning adult survivors of CM?

Method

Twenty in-depth interviews were held with high-functioning working adults who were maltreated as children. Phenomenological analysis was applied to the retrospective data reported in these interviews.

Result

Rich descriptions of work-related positive psychological changes were provided by all participants. Analysis revealed that survivors' post-traumatic growth corresponded with all five previously recognized domains of growth: changes in self, relating to others, openness to new possibilities, finding meaning to the abuse, and appreciation of life. It also revealed that work is perceived as a form of resistance (a subtheme of changes in self), and that finding meaning entails three emerging subthemes: being a survivor and a role model, giving others what was needed and never received, and making a better world.

Discussion

While the vocational lives of survivors of childhood maltreatment have rarely been examined through the lens of post-traumatic growth, our results show this lens to be highly valuable. Work-related post-traumatic growth has relevance not only regarding vocational traumas occurring in adulthood as has been previously studied, but also in the context of childhood traumas. Moreover, our research broadens the understanding of the possible domains of work-related growth.

Distinct trajectories of suicidal behaviors throughout the university stage and associated risk and protective factors: A large-scale prospective study

BACKGROUND

Suicide is a major public health concern, especially among adolescents and young adults. Although research has begun to explore the developmental trajectories of suicide-related outcomes, most have thus far focused on children and adolescents. The current study extends existing literature by identifying subgroup trajectories and related factors of college students over a two-year period.

METHODS

The data used in this study was obtained from an ongoing longitudinal study in Guangdong, China. A total of 3871 students participated in assessments performed at three time points at one-year assessment intervals. Growth mixture modeling (GMM) was used to estimate trajectory classes for suicidal behaviors, followed by multivariable logistic regression to explore the association between predictive factors and classes.

RESULTS

GMM analyses extracted two distinct trajectories of suicidal behaviors: a low-decreasing group (n = 3669, 94.8 %) and a high-increasing group (n = 202, 5.2 %). Multivariate logistic regression analyses revealed that depressive symptoms, non-suicidal self-injury, hopelessness, and childhood emotional abuse served as risk factors for the high-increasing group, while reasons for living served as protective factors.

CONCLUSIONS

Psychological interventions aimed at reducing the influence of risk factors and bolstering reasons to live may help to decrease the risk of suicide behaviors in college students.

Interaction effect between childhood abuse and interleukin-1β levels on suicidality in depressed patients

INTRODUCTION

The roles of childhood abuse and interleukin (IL)-1β levels, a representative pro-inflammatory cytokine, in suicidal behavior are unclear. This study investigated the main and interactive effects of childhood abuse and IL-1β levels on suicidal behavior in patients with a depressive disorder before and after pharmacological treatment.

METHODS

At baseline, exposure to self-reported childhood abuse, including emotional, physical, and sexual abuse, before the age of 16 years, and IL-1β levels, were measured in 1,094 outpatients with a depressive disorder, 884 of whom were followed for 1 year. Suicidal behavior was evaluated, including previous suicide attempts (at baseline), suicidal ideation (at baseline and follow-up), and fatal/non-fatal suicide attempts (at follow-up). The main and interaction effects of self-reported childhood abuse and IL-1β level on the four types of suicidal behavior were analyzed using logistic regression after adjusting for covariates.

RESULTS

Individual associations of self-reported childhood abuse were significant only with previous suicidal attempt but not with other suicidal behaviors. There was no significant association of plasma IL-1β level with any suicidal behavior. There were significant interactive associations of self-reported childhood abuse and a high IL-1β level on previous suicide attempts, baseline suicidal ideation, and fatal/non-fatal suicidal attempts during follow-up.

CONCLUSION

Suicidal behavior in patients with a depressive disorder could be influenced by considering the interactive effect of childhood abuse and IL-1β levels. Our study suggests that childhood trauma and biochemical factors play roles in the pathology of suicide in depressed patients.

Direct and Indirect Effects of Child Maltreatment on Suicidal Ideation among Chinese Left-Behind Children: Does Gender Make a Difference?

Previous studies indicate that maltreatment is related to children’s suicidal ideation, but the indirect mechanisms of left-behind children have been rarely investigated in the Chinese context. On the basis of a left-behind children sample (N = 1355; 57.1% females), this study aims to investigate the direct and indirect effects of maltreatment on suicidal ideation among Chinese left-behind children. The results of structural equation modeling (SEM) demonstrate that child maltreatment not only directly affects the suicidal ideation of left-behind children, but can also indirectly affect their suicidal ideation through the partially mediating role of self-efficacy. Moreover, a significant gender difference was found in the direct effect of maltreatment on suicidal ideation, with females experiencing stronger influence than males. Findings suggest that the effect of maltreatment on the suicidal ideation of left-behind children is mediated by self-efficacy and moderated by gender. Findings also highlight intervention directions for risk behaviors among left-behind children.

Is the end in the beginning? Child maltreatment increases the risk of non-suicidal self-injury and suicide attempts through impaired personality functioning

BACKGROUND

Child maltreatment is a risk factor for a range of mental disorders later in life, including dangerous self-harm and suicide attempts. A better understanding of the mechanisms underlying this association can inform prevention and intervention.

OBJECTIVE

To investigate personality functioning as a potential mediator of the association of childhood abuse and neglect and self-harm and suicide attempts in the general population.

PARTICIPANTS AND SETTING

Data were drawn from a representative German population sample (N = 2510).

METHODS

Participants filled out the Childhood Trauma Questionnaire (CTQ), OPD Structure Questionnaire (OPD-SQS), and items of the Self-Injurious Thoughts and Behaviors Interview (SITBI). In structural equation models, we operationalized impaired personality functioning as the mediator between childhood abuse and neglect and self-harm.

RESULTS

Individuals with a history of self-harm (combining suicide attempts, N = 47, and non-suicidal self-injury, N = 83) reported more childhood abuse and neglect (d = 1.39, p < .001) and greater impairments in personality functioning (d = 1.64, p < .001) than the rest of the population. The indirect effect via personality functioning accounted for 48.8 % of the total effect of childhood abuse and neglect on self-harm. In more differentiated analyses, emotional abuse showed the strongest association with self-harm. Only physical and sexual abuse had direct effects.

CONCLUSIONS

The results specify the relationship between child maltreatment and self-harm by demonstrating that it is partly mediated by basic functions of personality assessed using a dimensional measure. These abilities constitute modifiable risk factors that can be addressed by psychotherapy.

Interrelationships between childhood maltreatment, depressive symptoms, functional impairment, and quality of life in patients with major depressive disorder: A network analysis approach

BACKGROUND

Childhood maltreatment continues to pose a great challenge to psychiatry. Although there is growing evidence demonstrating that childhood maltreatment is an important risk factor for depressive disorders, it remains to be elucidated which specific symptoms occur after exposure to different kinds of childhood maltreatment, and whether certain pathways may account for these associations.

PARTICIPANTS AND SETTINGS

A total of 203 adult patients (18-53 years old) with MDD, diagnosed by Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria, were recruited from the outpatient clinic of Beijing Anding Hospital, Capital Medical University.

METHODS

Childhood maltreatment, depressive symptoms, functional impairment, and quality of life were evaluated by the Childhood Trauma Questionnaire - Short Form (CTQ-SF), 17-item Hamilton Depression Rating Scale (HAMD-17), Sheehan Disability Scale (SDS), and Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form (Q-LES-Q-SF). Undirected network analysis was used to explore the most relevant connections between them. Bayesian network analysis was used to estimate a directed acyclic graph (DAG) while investigating the most likely direction of the putative causal association.

RESULTS

In network analysis, the strongest edges were a positive correlation between emotional abuse and suicidal behavior as well as a negative association between emotional neglect and age of onset. In DAG analysis, emotional abuse emerged as the most pivotal network node, triggering both suicidal behaviors and depression symptoms.

CONCLUSIONS

Emotional abuse appears to be an extremely harmful form of childhood maltreatment in the clinical presentation of depression. This study has promise in informing the clinical intervention of depression.

Epidemiology of Childhood Trauma and Analysis of Influencing Factors in Psychiatric Disorders Among Chinese Adolescents: A Cross-sectional Study

Childhood trauma (CT) can lead to long-term psychiatric disturbances. The current study investigated the prevalence of CT and its associated risk factors among Chinese adolescents with psychiatric disorders. Adolescents were recruited from a large study on mental health in the Hunan province of China in 2014. The study had a two-phase cross-sectional design. Patients with mental disorders (n = 907) and healthy subjects (n = 2,240) completed the Childhood Trauma Questionnaire-Short Form. Of all types of CT, emotional neglect (EN; 48.44%-68.82%) and physical neglect (PN; 60.0%-72.1%) were most common among adolescents. The experience of emotional abuse (EA), physical abuse (PA), sexual abuse (SA), EN, and multiple types of trauma (≥3) was higher among adolescents with psychiatric disorders than the healthy comparison group. Moreover, the results of logistic regression analysis showed that living in semi-urban areas and villages, having a sibling, and having bad-to-average academic performance were risk factors for CT among adolescents with psychiatric disorders (p < .05). In additional, the results of logistic regression analysis revealed that being a left-behind child and bad academic performance were risk factors for experiencing multiple types (≥3) of CT (p < .05), while being female and having siblings were found to be protective factors against (≥3) CT (p < .05). In summary, the prevalence rate of CT (especially multiple types of trauma) is high among adolescents with psychiatric disorders. These results indicate the importance of reducing CT to limit the likelihood of psychiatric disorders, especially among adolescents.

How do physical and emotional abuse affect depression and problematic behaviors in adolescents? The roles of emotional regulation and anger

BACKGROUND

Rates of physical and emotional abuse are high among Chinese adolescents and elicit distinct psychopathologies. However, it remains unclear whether physical and emotional abuse relate to depression and behavior problems similarly or differently. In addition, few studies have examined if they share underlying mechanisms in adolescents.

OBJECTIVE

This study used longitudinal data to examine the mechanisms underlying the effect of physical and emotional abuse on depression and problematic behaviors through emotional regulation and anger in Chinese adolescents.

PARTICIPANTS AND SETTINGS

Participants were 1689 adolescents (with age ranging from 12 to 17 years) from junior and senior high schools in Zhejiang Province, China.

METHODS

Participants completed a childhood trauma questionnaire and an emotion regulation strategies questionnaire at time 1 (T1), and they completed an anger scale, a depression scale, and a problematic behaviors questionnaire one year later (T2). Structural equation modeling was used to examine the research hypotheses.

RESULTS

Physical abuse had direct positive effects on problematic behaviors but not on depression. However, emotional abuse had direct effects on depression and problematic behaviors, and indirect effects on both psychopathologies through expressive suppression and anger.

CONCLUSIONS

Physical and emotional abuse had distinct effects and influencing mechanisms on adolescents' externalizing and internalizing problems. Compared with physical abuse, emotional abuse elicited more harms and subsequent psychopathologies.

The mediating role of attachment and mentalising in the relationship between childhood maltreatment, self-harm and suicidality

BACKGROUND

Although the relationship between childhood maltreatment, self-harm and suicidality is well-established, less is known about the mediating mechanisms explaining it. Based on a developmental mentalisation-based theoretical framework, childhood adversity compromises mentalising ability and attachment security, which in turn increase vulnerability to later stressors in adulthood.

OBJECTIVE

This study aimed to investigate the role of attachment and mentalising as potential mechanisms in the relationship between childhood maltreatment, self-harm and suicidality.

PARTICIPANTS AND SETTING

We recruited 907 adults from clinical and community settings in Greater London.

METHODS

The study design was cross-sectional. Participants completed self-report questionnaires on retrospectively rated childhood trauma, and current attachment to the romantic partner, mentalising, self-harm, suicidal ideation and attempt. We used structural equation modelling to examine the data and conceptualized childhood maltreatment as a general factor in a confirmatory bifactor model.

RESULTS

The results showed that childhood maltreatment was both directly associated with self-harm and suicidality and indirectly via the pathways of attachment and mentalising.

CONCLUSIONS

These findings indicate that insecure attachment and impaired mentalising partially explain the association between childhood maltreatment, self-harm and suicidality. Clinically, they provide support for the potential of mentalisation-based therapy or other psychosocial interventions that aim to mitigate the risk of self-harm and suicidality among individuals who have experienced childhood maltreatment via increasing understanding of self and other mental states.

Association between Childhood Maltreatment and Suicidal Ideation: A Path Analysis Study

Epidemiological studies have suggested that childhood maltreatment increases suicidal ideation, and dissociative symptoms and hopelessness are involved in this relation. To better address this issue, we used a path analysis model to examine the role of different types of childhood maltreatment on suicidal ideation, investigating whether hopelessness and dissociative symptoms mediated this relation. A sample of 215 adult psychiatric inpatients was enrolled between January 2019 and January 2020, at the psychiatric unit of Sant’Andrea Medical Center in Rome, Italy. The Childhood Trauma Questionnaire (CTQ), Beck Hopelessness Scale (BHS), Dissociative Experiences Scale (DES-II), and Columbia-Suicide Severity Rating Scale (C-SSRS) were used to test the hypotheses. Results revealed that the presence of sexual abuse directly affected suicidal ideation (β = 0.18, SE = 0.8, p < 0.05), while emotional abuse and neglect indirectly increased suicidal ideation via dissociation (β = 0.05, SE = 0.02, 95% C.I. 0.01/0.09) and hopelessness (β = 0.10, SE = 0.03, 95% C.I. = 0.04/0.16). Professionals working with children should be aware of the long-term consequences of childhood maltreatment, particularly suicide risk. Furthermore, professionals working with adults should inquire about past childhood maltreatment.

Emotion Regulation and Depressive Symptoms Mediate the Association Between Schizotypal Personality Traits and Suicidality in Chinese College Students

OBJECTIVE

The psychological mechanisms underlying the relationship between schizotypal personality traits and suicidality are not understood. This study investigated the association of schizotypal personality traits with suicidality and explored the mediating role of cognitive appraisal and depression in the relationship between those two variables in a sample of Chinese college students.

METHOD

Participants (N = 2457) completed the Schizotypal Personality Questionnaire, the Emotional Regulation Questionnaire, the Zung Self-rating Depression Scale, and three questions related to suicidality.

RESULTS

The cognitive reappraisal score was lower in the students with suicidality than the students without suicidality, whereas scores for depression and schizotypal personality traits were higher in the students with suicidality than the students without suicidality. Schizotypal personality traits and depression were risk factors for suicidality. Depression mediated the association between schizotypal personality traits and suicidality. Cognitive reappraisal negatively affected symptoms of depression and had a significant mediating effect on the association between schizotypal personality traits and suicidality.

CONCLUSIONS

Schizotypal personality traits and depression are risk factors for suicidality. Cognitive reappraisal and depression mediate the association between schizotypal personality traits and suicidality.

Addressing the biological embedding of early life adversities (ELA) among adults through mindfulness: Proposed mechanisms and review of converging evidence

Early life adversities (ELA) are prevalent and have a profound and adverse impact across the lifespan, including on age-related health outcomes, yet interventions to remediate its adverse impact are scarce. This paper presents evidence for mindfulness training to reduce the elevated mental and physical health risks linked to ELA among adults by targeting biological mechanisms of ELA leading to these adverse health outcomes. We first provide a brief overview of ELA, its adverse health impacts, and mechanisms that might be responsible. Next, we review converging evidence that demonstrates that mindfulness training influences key biological pathways involved in ELA-linked negative health consequences, including (a) brain networks involved in self-regulation, (b) immunity and inflammation, (c) telomere biology, and (d) epigenetic modifications. Further, we review preliminary evidence from mindfulness-based trials that focused on populations impacted by ELA. We discuss limitations of this review and provide recommendations for future research. If effective, a mindfulness-based approach could be an important public health strategy for remediating the adverse mental and physical health consequences of ELA.

Neurocognitive functioning and impulsivity in first-episode psychosis with suicidal ideation and behavior: A systematic review

BACKGROUND

The prevalence of suicidal ideation (SI) and behavior (SB) among people suffering from psychotic disorders is a public health issue. Most suicide attempts (SAs) occur before or during the early phases of first-episode psychosis (FEP). Improving knowledge about the suicide risk in the early stages is essential to develop therapeutic and prevention strategies. We conducted a systematic review to investigate an association between neurocognitive impairments or a history of impulsive behavior and SI or SB among patients with FEP.

METHOD

PRISMA guidelines were followed. Ten databases were searched using MeSH terms or key-words related to FEP, impulsivity or cognitive functioning measures and SI or SB, without restrictions for study design or length of follow-up. Included studies evaluated at least one cognitive function with neuropsychological tests or validated questionnaires, or provided records of impulsive behavior.

RESULTS

Twenty one research papers were included from databases, bibliographic references or expert opinions. Among patients with FEP, seven studies showed more pronounced neuropsychological impairments, especially regarding attention, processing speed, executive functioning and theory of mind in patients that had attempted suicide. No association was found between cognitive impairments on neuropsychological tests and SI. Previous non-suicidal impulsive behaviors were associated with SAs and suicide.

CONCLUSION

Our review suggests an association between neurocognitive impairments and SAs among patients with FEP. Records of impulsive behavior are also associated with SB in that population. Further research on the neuropsychology of FEP is necessary to identify how these impairments facilitate SB and evaluate their potential utility as therapeutic targets.

Suicidal Histories in Adults Experiencing Psychological Trauma: Exploring Vulnerability and Protective Factors

OBJECTIVE

This study aimed to identify vulnerability and protective factors for suicidal histories among adults experiencing psychological trauma.

METHOD

Adults seeking treatment for psychological trauma (N = 113) completed self-report questionnaires measuring childhood trauma history, self-concept, relational functioning, emotion regulation, living arrangements, employment status, marital status, and suicidal history. Independent samples t-tests were used to determine variables on which those with and without suicidal histories differed significantly. These variables were then entered into a binary logistic regression model to identify factors which independently distinguished between those with and without a suicidal history.

RESULTS

Univariate differences were found for childhood emotional abuse (CEA), childhood emotional neglect (CEN), emotion deactivation, and employment status, with those in the suicidal history group scoring higher on all of these. CEA (OR = 1.13, 95% CI = 1.01-1.27) and employment status (OR = 4.12, 95% CI = 1.23-13.73) remained significant predictors of suicidal status in the multivariable logistic regression.

CONCLUSIONS

CEA was an independent vulnerability factor for suicidal risk, highlighting the need for clinicians to assess exposure to such trauma in those presenting with proximal traumatic experiences. Being in employment was an independent protective factor against suicidal risk, highlighting the importance of social buffers or networks when faced with traumatic situations.

Suicidality in patients with premenstrual dysphoric disorder-A systematic review and meta-analysis

BACKGROUND

Whether premenstrual dysphoric disorder (PMDD) is correlated with the risk of suicidality and the extent of its effect on suicidality are unclear. The present study was conducted to elucidate the association between PMDD and suicidality from relevant studies.

METHODS

Four electronic databases, namely, Scopus, Embase, PubMed, and Web of Science, were searched from inception to November 15, 2020. Quality assessment, data synthesis, and sensitivity analysis were performed on the included studies.

RESULTS

Six studies with 8 532 participants were included in this meta-analysis. PMDD was associated with an increased risk of suicidal ideation (odds ratio [OR]=2.34, 95% confidence interval [CI]=1.50-3.18, I²=0.0%, p=0.99, k=4). Patients with PMDD had a greater risk of experiencing suicide attempt (OR=2.13, 95% CI=1.05-3.21, I²=0.0%, p=0.81, k=5). PMDD was associated with an increased risk of suicidal plan (OR=2.24, 95% CI=1.03-3.45, I²=0.0%, p=0.96, k=2).

LIMITATIONS

The diagnosis of PMDD should be considered "provisional" in all the included studies.

CONCLUSIONS

Among PMDD sufferers there would be a group of particularly suicidal women. Clinicians who treat patients with PMDD should be vigilant for signs of suicidal ideation and behavior to implement better treatment and preventive measures.

Sleep problems and emotional dysregulation mediate the relationship between childhood emotional abuse and suicidal behaviors: A three-wave longitudinal study

BACKGROUND

Suicide is a major public health safety concern among youth. Childhood emotional abuse is one of the most widely recognized risk factors for suicidal behaviors. However, little is known about the role of sleep problems and emotion dysregulation in this relationship.

METHODS

This study is part of a large-scale health-related cohort among Chinese college students. A total of 7434 participants who completed the first three waves of data collection were used for data analysis. All participants completed questionnaires regarding childhood emotional abuse (Wave 1), sleep problems and emotional dysregulation (Wave 2), and suicidal behaviors (Wave 3). Mediation analyses with bootstrapping were conducted to investigate the mediating role of sleep problems and emotional dysregulation in the relationship between childhood emotional abuse and suicidal behaviors.

RESULTS

The results showed that the prevalence of childhood emotional abuse and suicidal behaviors were 8.7% and 5.9%, respectively. Findings from mediation analysis showed that sleep problems and emotional dysregulation served both parallel and sequential mediating roles in the relationship between childhood emotional abuse and suicidal behaviors.

LIMITATIONS

All measures were based on self-report instead of objective assessments or clinical diagnostic evaluations.

CONCLUSIONS

Psychological interventions aimed at developing healthy sleep habits and emotion regulation skills may be helpful in decreasing the risk of suicidal behaviors, especially for suicide ideators with childhood emotional abuse.

Suicidality in childhood abuse survivors - the contribution of identification with the aggressor

OBJECTIVE

Childhood abuse survivors are at risk for suicidal ideation and suicide attempts. Research has indicated that posttraumatic stress disorder (PTSD) symptoms and dissociation are related to elevated suicidal ideation and behavior (SIB) among this population. At the same time, although the theoretical and clinical literature in the trauma field have suggested that survivors' pathological attachment to their perpetrators, known as identification with the aggressor, might explain SIB, this supposition has not been investigated to date.

METHOD

Filling this gap, this study explored the associations between identification with the aggressor, PTSD symptoms, dissociation, and SIB among 589 adult survivors of childhood abuse.

RESULTS

Identification with the aggressor, PTSD symptoms, and dissociation were related to elevated levels in suicidal ideation and behavior. Furthermore, profile type (namely, having high versus medium or low levels of identification with the aggressor, PTSD symptoms, and dissociation) was implicated in participants' SIB: Participants who adhered to a profile characterized by high levels of identification with the aggressor, PTSD symptoms, and dissociation had higher levels of suicide risk and suicidal ideation, as well as higher odds of reporting a history of suicide attempts, compared to participants who adhered to the other two profiles (i.e., characterized by medium or low levels of identification with the aggressor, PTSD symptoms, and dissociation).

LIMITATIONS

This study relied on convenience sampling and a cross-sectional design.

CONCLUSIONS

Identification with the aggressor might serve, alongside PTSD symptoms and dissociation, as a risk factor for suicidal ideation and behavior among childhood abuse survivors.

Traumatic life-events and suicidality among Mexican adolescents as they grow up: A longitudinal community survey

OBJECTIVE

Limited research exists on the impact of type and number of traumatic events on the incidence of suicide ideation and attempts (suicidality) among adolescents in low/middle income countries where violence is common.

METHOD

We estimated prospective associations of 7 types of events on the new occurrence of suicidality from a follow-up conducted in 2013 (n = 1071; ages 19-26) of the original Mexican Adolescent Mental Health Survey conducted in 2005 (ages 12-17), by using Hazard Ratios (HR) estimates.

RESULTS

For new onset of suicide ideation, those reporting "Ever raped or sexually assaulted" had the highest adjusted HR (3.8), followed by "Ever other traumatic event" (HR = 1.9), "Ever committed or witnessed violence" (HR = 1.7) and "Beaten as a child or witnessed physical fights at home" (HR = 1.5). For suicide attempt, those reporting "Ever beaten up by spouse, partner, someone else, mugged with a weapon, or stalked" (HR = 3.8) and "Ever other traumatic event" (HR = 2.0) had the higher hazards. Compared to those without a traumatic event, increased hazards of ideation and attempt were found for those reporting a greater number of types of events.

CONCLUSIONS

Our sample is representative of the largest metropolitan area in Mexico but does not include other cities or age groups that may differ in risk factors. Traumatic events that happened in the eight years between waves are not considered. Traumatic events increased the risk of suicidality, independent of common mental disorders. Identifying and addressing these events in clinical settings may therefore be important for preventing suicide in this population.

A latent class analysis of physical, emotional, and sexual abuse history among suicidal inpatients

OBJECTIVE

Physical, emotional, and sexual abuse are subtypes of childhood abuse that may persist into adulthood. This study applied latent class analysis to describe the pattern of co-occurrence of these three abuse subtypes during childhood and adulthood and examined latent class differences in psychosocial characteristics and three types of suicide attempt history (aborted, interrupted, and actual).

METHODS

Data were drawn from a high-risk sample of 115 military service members and adult beneficiaries who were psychiatrically hospitalized following a suicide-related crisis.

RESULTS

Three latent classes were identified: Multiple and Persistent Abuse (Class One: 29.6%), Childhood Physical and Persistent Emotional Abuse (Class Two: 27.0%), and Minimal Abuse (Class Three: 43.5%). Females were more likely than males to report a history of Multiple and Persistent Abuse. After controlling for gender, the Multiple and Persistent Abuse Class had higher scores of depressive symptoms and hazardous drinking, poorer sleep quality, and increased social stress than the Minimal Abuse Class. Moreover, the Multiple and Persistent Abuse Class was associated with increased likelihood of lifetime interrupted suicide attempt (Odds Ratio [OR] = 3.81, 95% CI = 1.20, 12.07) and actual suicide attempt (OR = 3.65, 95% CI = 1.23, 10.85), and had the greatest number of total actual suicide attempt (1.82 times on average).

CONCLUSION

Co-occurrence of multiple subtypes of abuse across development is associated with higher psychosocial risk and history of suicide attempt. The assessment of specific subtypes of abuse and their timing may inform case conceptualization and the management of suicide risk among psychiatric inpatients.

Disparities in Childhood Abuse Between Transgender and Cisgender Adolescents

BACKGROUND AND OBJECTIVES

Transgender adolescents (TGAs) exhibit disproportionate levels of mental health problems compared with cisgender adolescents (CGAs), but psychosocial processes underlying mental health disparities among TGAs remain understudied. We examined self-reported childhood abuse among TGAs compared with CGAs and risk for abuse within subgroups of TGAs in a nationwide sample of US adolescents.

METHODS

Adolescents aged 14 to 18 completed a cross-sectional online survey (n = 1836, including 1055 TGAs, 340 heterosexual CGAs, and 433 sexual minority CGAs). Participants reported gender assigned at birth and current gender identity (categorized as the following: cisgender males, cisgender females, transgender males, transgender females, nonbinary adolescents assigned female at birth, nonbinary adolescents assigned male at birth, and questioning gender identity). Lifetime reports of psychological, physical, and sexual abuse were measured.

RESULTS

Seventy-three percent of TGAs reported psychological abuse, 39% reported physical abuse, and 19% reported sexual abuse. Compared with heterosexual CGAs, TGAs had higher odds of psychological abuse (odds ratio [OR] = 1.84), physical abuse (OR = 1.61), and sexual abuse (OR = 2.04). Within separate subgroup analyses, transgender males and nonbinary adolescents assigned female at birth had higher odds of reporting psychological abuse than CGAs.

CONCLUSIONS

In a nationwide online sample of US adolescents, TGAs had elevated rates of psychological, physical, and sexual abuse compared with heterosexual CGAs. Risk for psychological abuse was highest among TGAs assigned female at birth. In the future, researchers should examine how more frequent experiences of abuse during childhood could contribute to disproportionate mental health problems observed within this population.

Child abuse and suicidality in the context of the Interpersonal Psychological Theory of Suicide: A network analysis

OBJECTIVES

While there is evidence for an association of child abuse with suicidality in the course of life, the underlying mechanisms remain unclear. The Interpersonal Psychological Theory of Suicide (IPTS) provides a theoretical framework to investigate this relationship. The present study examines how different subtypes of child abuse are related to suicidal ideation and to attempts in the context of the IPTS.

METHODS

146 psychiatric inpatients (M = 37.9 years, 62% female) with an acute suicidal crisis (n = 71) or a recent suicide attempt (n = 74) were examined at baseline (T0) and six (T1) months later. We measured emotional, physical, and sexual abuse, the constructs of the IPTS (thwarted belongingness, perceived burdensomeness, and capability for suicide) and suicidal ideation as well as suicide attempts. Using the statistics program R, a network analysis of all named constructs was conducted. Centrality measures were computed.

RESULTS

Emotional abuse was the most central kind of abuse in the network and had a direct relationship with suicide attempts and an indirect relationship with suicidal ideation via perceived burdensomeness. Physical and sexual abuse showed no significant relations with the different constructs of the IPTS.

CONCLUSION

The major limitation of this study was the modest sample size which reduced the number of variables able to be included in the network. Regarding child abuse, the results underline that emotional abuse plays a central role in this network and may be important for suicide risk assessment. Future research should address this topic in a larger sample.

PRACTITIONER POINTS

Emotional abuse was the most central kind of abuse in this network analysis. Sexual abuse was the only kind of abuse with a direct relation to suicidal ideation. Capability for suicide had just a marginal position in the network analysis. Early interventions addressing the effects of child abuse are recommended. Replications in larger samples and with more relevant variables are needed.

Psychological maltreatment: Definition and reporting barriers among American professionals in the field of child abuse

BACKGROUND

Despite reliable definitions and evidence of harm to children, psychological maltreatment (PM) is significantly less reported to Child Protective Services than physical or sexual abuse in the United States (U.S. Department of Health and Human Services, 2016).

OBJECTIVE

The goal of this study was to identify factors influencing identification and intent to report psychological maltreatment.

PARTICIPANTS AND SETTING

The sample was comprised of membership of the American Professional Society on the Abuse of Children (APSAC), a multi-disciplinary group of professionals in the field of child maltreatment.

METHODS

An anonymous online survey was administered with a 39 % (N = 538) response rate.

RESULTS

Only 4 of the 18 items, preselected by experts as representing all PM subtypes in the APSAC- endorsed definition (Hart, Brassard, Baker, & Chiel, 2019), were identified by most respondents as definitely PM. Most respondents believed that PM was associated with harmful outcomes "sometimes" or "mostly." Respondents revealed an intent to report to CPS only 4 of the 18 PM behaviors. Identification of a behavior as PM and as harmful predicted intent to report, explaining between 8-11 percent of the variance.

CONCLUSION

Professionals in the field of maltreatment need more training on identification and reporting of PM. A model definition of PM should be developed in order to increase reliability of identification of psychological maltreatment.

Prevalence and correlates of non-suicidal self-injury, suicidal ideation, and suicide attempt among children and adolescents: Findings from Uganda and Jamaica

BACKGROUND

Youth non-suicidal self-injury (NSSI) and suicide are major public health concerns, but limited data are available on the prevalence and correlates of these problems in developing countries. The aim of this study is to describe experiences of three suicidal phenomena (NSSI, suicidal ideation [SI], and suicide attempt [SA]) among children and adolescents from two developing countries. We also examine how depression, anxiety, sleep problems, child maltreatment, and other socio-demographic variables associate with the risk of NSSI only, SI only, SA only, and co-occurring NSSI/SI/SA.

METHODS

We conducted a population-based cross-sectional study of school-based Ugandan and Jamaican children and adolescents. Participants were 11,518 (52.4% female) Ugandan and 7,182 (60.8% female) Jamaican youths aged 9-17 years.

RESULTS

The estimated lifetime prevalence of NSSI, SI, and SA was 25.5%, 25.6%, and 12.8% respectively among Ugandan boys and 23.2%, 32.5%, and 15.3% respectively among Ugandan girls. As for the Jamaican sample, the estimated lifetime prevalence of NSSI, SI, and SA was 21%, 27.7%, and 11.9% respectively among boys and 32.6%, 48.6%, and 24.7% respectively among girls. The odds of experiencing SI only, SA only, and co-occurring NSSI/SI/SA were significantly elevated among participants with mild, moderate, and severe depression in both countries.

LIMITATIONS

The current study relied on retrospective data.

CONCLUSIONS

This study found that suicidal phenomena are common among youths from Uganda and Jamaica, with rates substantially higher than among youths from high-income countries. The risk of suicidal phenomena was especially high among youths with severe depression.

Fear of sleep and sleep quality mediate the relationship between trauma exposure and suicide attempt in adolescents

Prior work has established bivariate associations between suicidal thoughts and behaviors, trauma exposure and sleep disturbance broadly. Specifically, this study tested whether fear of sleep and sleep quality mediated the association between trauma exposure and suicide attempt. Participants (N = 100) were adolescents admitted to an inpatient psychiatric program for suicidality. Trauma exposure history was retrieved from admission notes and participants completed self-report surveys assessing sleep quality, fear of sleep and number of suicide attempts within the previous month. Structural equation modelling was used to investigate the relationships between childhood trauma, fear of sleep, sleep quality, and suicide attempt. Path analysis was used to investigate the indirect effects from trauma exposure to suicide attempt through fear of sleep, and sleep quality. Path analysis revealed a significant indirect effect from trauma exposure to suicide attempt through fear of sleep and sleep quality. Our findings suggest that a significant portion of the association between trauma exposure and suicide attempts in adolescence may be explained by the negative impact of trauma exposure on sleep. Fear of sleep may increase the risk of a suicide attempt by negatively impacting sleep quality. Future studies should investigate whether interventions targeting sleep and fear of sleep reduce the association between trauma and suicide attempt.

"How many times did I not want to live a life because of him": the complex connections between child sexual abuse, disclosure, and self-injurious thoughts and behaviors

BACKGROUND

Meta-analyses have confirmed an association between child sexual abuse (CSA) and non-suicidal and suicidal self-injurious thoughts and behaviors (SITB), yet the mechanisms linking these factors are, to date, poorly understood. The goal of the current study is to explore one potential influencing factor acting in the association between CSA and SITB, which is the disclosure experience. Disclosure has been identified as a prominent factor in the healing process of survivors, with a lack of support following disclosures heightening negative outcomes. Exploring the impact of CSA disclosure on SITB is necessary to build effective prevention and intervention strategies.

METHODS

This qualitative study is part of a larger initiative spanning diverse research sites in Canada and in Ireland and aiming to lend voice to young people who were sexually abused in childhood/adolescence. Participants were recruited from community-based sexual abuse/assault agencies, hospital-based specialized clinics and child advocacy centres. The Long Interview Method, based on a branch of phenomenology, was used to guide research design and data collection. The current thematic analysis, informed by a stress-diathesis model, is based on a sample comprised of 21 ethnically diverse youth aged 15 to 25 who self-reported a sexual abuse experience in their childhood or teenage years and who, as part of the interview on their disclosure processes, revealed past or current SITB.

RESULTS

The thematic analysis led to the identification of four main themes that both confirmed past research and conceptual models on SITB, and provided new insights. Participants perceived a clear link between their CSA experience and SITB and other mental health issues. They offered their views on the meanings of SITB for CSA victims: to cope with abuse; to end the abuse; to express self-hatred and loneliness; and to let people know about their suffering. They described how negative disclosure experiences led to more nonsuicidal and suicidal SITB. Yet, participants also revealed that receiving support for their SITB created opportunities for CSA disclosure and support.

CONCLUSIONS

This study showed complex connections between CSA experiences, disclosure and nonsuicidal and suicidal SITB. Understanding the reciprocal influences between SITB, CSA disclosure and help-seeking could better equip mental health professionals and caregivers to provide support and foster healing and recovery in CSA victims.

Integrating a Sport-Based Trauma-Sensitive Program in a National Youth-Serving Organization

There is a pressing need to equip youth-serving community organizations to respond to the unique needs of trauma-exposed children. Early prevention measures can be an effective means of redirecting children to self-regulatory healing, while facilitating their transition toward strength-based thriving. Sport can offer a powerful opportunity to reach these children; however there remains little information on how to effectively develop, deliver, evaluate, and sustain trauma-sensitive sport programs in a community context. The purpose of this paper is to outline a case study of integrating sport-based trauma-sensitive practices with BGC Canada's national Bounce Back League program. An interdisciplinary partnership of academic, community, and practice experts used a community-based participatory action research approach, paired with a knowledge translational approach, to guide the process of program development. Mixed methods (e.g., surveys, logbooks, interviews, focus groups, online communications) were used to generate ongoing insights of staff's training experiences, successes and challenges of program implementation, and potential impact of program on club members. Several stages of program development are described, including: (a) collaboratively planning the program; (b) piloting the program to three clubs; (c) adapting the program using pilot insights; (d) expanding the adapted program to ten clubs; and (e) creating opportunities to maintain, sustain, and scale-out practices throughout grant duration and beyond. Lessons learned regarding the leadership team's experiences in terms of developing, adapting, and integrating trauma-sensitive practices in this community context are shared.

The Mediation Effect of Hyperarousal Symptoms on the Relationship Between Childhood Physical Abuse and Suicidal Ideation of Patients With PTSD

Objective: This study examined the relationship of childhood physical abuse, posttraumatic stress disorder (PTSD), depression, and suicide in patients with PTSD through path analysis. Materials and Methods: A total of 114 patients with PTSD (36 men and 78 women) were recruited and completed psychological assessments including the Childhood Trauma Questionnaire, the scale for suicidal ideation, the clinician-administered PTSD scale for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, the PTSD checklist, and the Hospital Anxiety and Depression Scale. Structural equation modeling was used to evaluate the results. We developed a model including childhood physical abuse experience as the causal variable, suicidal ideation as a result variable, and PTSD and depression as mediation variables. PTSD symptoms were divided into four clusters [intrusion, avoidance, negative cognition and mood, and altered arousal and reactivity (hyperarousal)] to determine predictive power for suicide. Results: PTSD symptoms fully mediated the relationship between childhood physical abuse and suicidal ideation. Furthermore, PTSD symptoms fully mediated the relationship between childhood physical abuse and depression. Among the PTSD symptoms, hyperarousal was the only symptom cluster that mediated the relationship between childhood physical abuse and suicidal ideation. The symptom clusters of negative cognition and mood as well as hyperarousal mediated the relationship between childhood physical abuse and depression. Conclusions: This study presents a link between childhood physical abuse and current symptoms in patients with PTSD, and highlights specific PTSD symptom clusters (i.e., hyperarousal, negative cognition and mood) that may increase the risk for psychopathology later in life.

Psychological maltreatment: An international challenge to children's safety and well being

BACKGROUND

Child psychological maltreatment (PM), also known as emotional abuse and neglect, mental violence, and emotional maltreatment, is the least recognized and addressed of the four major forms of child maltreatment.

OBJECTIVES

This article provides an 1) the history of PM and its relationship to children's rights, 2) an overview of the current state of knowledge, 3) implications of diversity for the topic of PM, 4) an example of a topic-relevant intervention, and 5) a vision for further progress in addressing this form of child maltreatment.

PARTICIPANTS AND SETTINGS

NA.

METHOD

Literature review, intervention description of fabricated or induced illness, and expert opinion.

RESULTS

PM is directly implicated in seven of the articles of the Convention. PM is common, reliable definitions of PM exist and need to be applied to practice and public health surveillance, harmfulness has been empirically established but is not fully appreciated, and countries vary dramatically in terms of incidence.

CONCLUSIONS

PM is a human rights issue that must be addressed through child protection and promotion of child wellbeing. Adoption of reliable definitions of the different aspects of PM for Child Protective Service practice is a top policy goal. The development of empirically supported curricula on PM for training professionals and parents and culturally sensitive interventions to change social norms on the use of psychologically aggressive disciplinary practices and other forms of PM are critical research needs. Well-validated interventions to support quality parent-child relationships and support families exist and need to be widely adopted. Individual child protective measures should be confined to cases of ongoing serious PM when interventions have failed to reduce harm to the child.
