Influence of Childhood Maltreatment on Machiavellianism

ABSTRACT Machiavellianism is characterized by manipulative behavior, lack of empathy, and a willingness to deceive and exploit others for personal gain. Research indicates that one factor that may increase the likelihood and severity of Machiavellianism in adulthood is maltreatment in childhood. However, few studies have attempted to untangle which specific instantiations of childhood maltreatment (e.g. abuse vs. neglect) are most associated with Machiavellianism. In our study, we investigate the association between childhood abuse and neglect on Machiavellianism in a sample of adult women and men recruited online (N = 278) using a Bayesian approach to multiple regression. Results suggest that higher levels of Machiavellianism are associated with physical neglect, with some influence of other forms of maltreatment depending on gender. These findings shed light on potential etiological influences on Machiavellianism and have implications for research on and clinical intervention with people with high levels of this trait.

Breaking the cycle: Identifying key symptom pathways of eating disorders and the influence of childhood maltreatment.

Most network analyses on central symptoms in eating disorders (EDs) have been cross-sectional. Longitudinal within-person analyses of therapy processes are scarce. Our aim was to investigate central change processes in therapy in a transdiagnostic sample, considering the influence of childhood maltreatment. We employed dynamic time warping analyses to identify clusters of symptoms that tended to change similarly across therapy on a within-person level. Symptoms were measured by a 28-item Eating Disorder Examination Questionnaire (EDE-Q). Furthermore, we examined the temporal direction of symptom change to identify symptoms that tended to precede and predict other symptoms. Finally, we estimated two directed, temporal networks in patients with and without a history of childhood maltreatment. Our analysis included 122 ED patients (mean age = 30.9, SD = 9.7; illness duration = 14.2 years, SD = 8.9; prior treatment = 5.6 years, SD = 5.1). The initial network revealed three robust clusters of symptoms over time: (1) ED behavior, (2) inhibition, and (3) cognitions and feelings about body and weight. Overvaluation of shape had the highest out-strength preceding and predicting other symptoms. Dissatisfaction with weight preceded and predicted other symptoms in the maltreatment network. The non-maltreatment network showed a similar structure to the transdiagnostic network. Targeting and monitoring feelings and cognitions related to shape may be crucial for achieving lasting symptom improvement in a transdiagnostic sample. Furthermore, our findings highlight the need for further investigation into the different processes driving EDs based on maltreatment status. There is limited understanding of the processes that occur for patients with eating disorders between admission and discharge in therapy, especially for patients with a history of childhood maltreatment. Our analyses suggest that changes in cognitions regarding shape precede and predict changes in cognitions about weight. Different processes may be driving the eating disorder according to maltreatment status, which might further illuminate the riddle of dropout and relapse in therapy for patients with a history of childhood maltreatment. These findings suggest the need for further investigation into the specific dynamics occurring during therapy for individuals with a history of childhood maltreatment.

Suicidality in civilian women with PTSD: Possible link to childhood maltreatment, proinflammatory molecules, and their genetic variations

BackgroundPosttraumatic stress disorder (PTSD) is a robust risk factor for suicide. Studies have suggested an association between suicide and elevated inflammatory markers, although such evidence in PTSD is scarce. Suicide risk, PTSD, and inflammatory molecules are all shown to be associated with childhood maltreatment and genetic factors. MethodsWe examined the association between suicidal ideation/risk and inflammatory markers in 83 civilian women with PTSD, and explored the possible influence of childhood maltreatment and inflammatory genes. Suicidal ideation and risk were assessed using the Beck Depression Inventory-II and the Mini-International Neuropsychiatric Interview. Childhood maltreatment history was assessed with the Childhood Trauma Questionnaire (CTQ). Blood levels of high-sensitivity C-reactive protein (hsCRP), interleukin-6 (IL-6) and high-sensitivity tumor necrosis factor-α were measured. Genetic polymorphisms of CRP rs2794520 and IL6 rs1800796 were genotyped. ResultsSuicidal ideation was significantly positively correlated with hsCRP (p = 0.002) and IL-6 (p = 0.015) levels. Suicide risk weighted score was significantly positively correlated with hsCRP (p = 0.016) levels. The risk alleles of CRP rs2794520 and IL6 rs1800796 leading to increased respective protein levels were dose-dependently associated with higher risk of suicide (p = 0.007 and p = 0.029, respectively). The CTQ total score was significantly correlated with suicidal ideation and risk, but not with inflammatory marker levels. Furthermore, a multivariate regression analysis controlling for PTSD severity and potential confounders revealed that rs2794520 and rs1800796, but not hsCRP or IL-6 levels, significantly predicted suicidal ideation (p < 0.001) and risk (p = 0.007), respectively. ConclusionGenetic variations within inflammatory genes might be useful in detecting PTSD patients at high risk of suicide.

Childhood Maltreatment and Creativity among Chinese College Students: A Serial Mediation Model

Creativity plays a very crucial impact on our cultural life and has also been important to the improvement of human civilization. Numerous studies have indicated that family circumstance plays an important role in the development of individual creativity. However, little is known about the mediating mechanisms underlying the association between childhood maltreatment and creativity. This study intended to explore the serial multiple mediation model in which undergraduates' cognitive flexibility and self-efficacy were proposed to mediate the potential influence of childhood maltreatment on their creativity. Participants were 1069 undergraduates (573 males and 496 females, mean age was 20.57 ± 1.24 years ranging from 17 to 24) from a university in Shandong Province, China. Participants were required to complete an internet survey including the Short Form of Childhood Trauma Questionnaire (CTQ-SF), General Self-Efficacy Scale (GSES), Cognitive Flexibility Inventory (CFI), and Williams Creativity Aptitude Test (WCAT). Serial multiple mediation analysis and the bootstrap method were used to investigate the mediation effects of cognitive flexibility and self-efficacy. The results showed that childhood maltreatment indirectly influenced undergraduates' creativity through three indirect paths: childhood maltreatment→cognitive flexibility→creativity, childhood maltreatment→self-efficacy→creativity, and childhood maltreatment→cognitive flexibility→self-efficacy→creativity. The ratios of the total indirect effects and branch-indirect effects to the total effects were 92.73%, 34.61%, 35.68%, and 22.44%, respectively. These results indicated that cognitive flexibility and self-efficacy could completely mediate the potential impact of childhood maltreatment on individuals creativity.

The influence of childhood maltreatment on trait depression in patients with major depressive disorder: A moderated mediation model of rumination and mindful attention awareness

Major depressive disorder (MDD) is one of the most prevalent psychiatric disorders. Individuals who were exposed to childhood maltreatment might be an especially vulnerable group and were more likely to meet the diagnostic criteria for depression than those who were not. Trait depression refers to a personality trait predisposition to depression, expressed as the frequency of symptoms rather than a transient depressive mood state. Clarifying the relationship between childhood maltreatment and trait depression in patients with MDD has therefore become an important field of research. Childhood Trauma Questionnaire-Short Form (CTQ-SF), Ruminative Responses Scale (RRS), State-Trait Depression Scale (ST-DEP), and Mindful Attention Awareness Scale (MAAS) were used as research instruments. SPSS 23.0 statistical software was used for statistical analysis and examined the moderated mediation models. A total of 288 patients with MDD were included in this study. After standardization of the variables, the model revealed childhood maltreatment was positively associated with trait depression (β = 0.215, p < 0.001) and that rumination partially mediated the effect between childhood trauma and trait depression. Mindfulness moderated the association between rumination and trait depression in depressed patients (β = 0.171, p < 0.001). Simple slope tests showed that rumination significantly predicted trait depression in patients with high levels of mindfulness (bsimple = 0.460, p < 0.001, 95%CI = [0.339, 0.581]), while this predictive effect was not significant in patients with low levels (bsimple = 0.119, p = 0.097, 95%CI = [−0.022, 0.261]). After adding mediating variables, we found that the negative impact of childhood maltreatment on trait depression was both directly and indirectly through the patients' own ruminative levels. However, mindfulness performed a critical moderating role in the overall mediating model, aggravating the negative impact of childhood maltreatment on trait depression. There are several limitations in this study: the history of childhood maltreatment was reviewed and reported; the MAAS was a single-dimensional questionnaire that fails to measure the content of other mindfulness factors; cross-sectional data could not be used to infer the causal relationship between variables.

Childhood maltreatment affects depression and anxiety: The mediating role of benign envy and malicious envy.

The influence of childhood maltreatment on depression and anxiety has been reported in many studies, and the mechanism of this influence has been described from different perspectives. However, few research has explored the influence of child maltreatment on depression and anxiety from the perspective of benign/malicious envy. Given that, based on social comparison theory, this study explored the mediating effect of benign envy/malicious envy on child maltreatment, depression, and anxiety. The sample of this study consisted of 2,691 Chinese adolescents. The results showed that benign and malicious envy both played a significant role in mediating the relation between childhood maltreatment and depression and anxiety. Interestingly, we found that there were different mechanisms of benign and malicious envy in this relationship, namely, malicious envy promoted the effects of childhood maltreatment on depression and anxiety, whereas benign envy inhibited the effects of childhood maltreatment on depression and anxiety. These findings not only reveal the different mechanisms between the two socially comparable emotions of benign/malicious envy in the early adverse environment and depression and anxiety, but also provide a specific reference for individuals to regulate the depression and anxiety caused by childhood maltreatment and envy.

Coping Style and Resilience Mediate the Effect of Childhood Maltreatment on Mental Health Symptomology.

Background: A well-known distal risk factor for mental health symptomology is childhood maltreatment. Previous research revealed that several mediators, such as coping style and resilience, might be connected to the psychological mechanism of childhood maltreatment on mental health symptomology. Objective: The purpose of this study was to assess how coping style and resilience affect the relationship between childhood maltreatment and mental health symptomology of college students. Methods: With the method of cross-sectional survey, 740 college students from China (Gansu Province) completed the Childhood Trauma Questionnaire (CTQ), the Simplified Coping Style Questionnaire (SCSQ), the Connor–Davidson Resilience Scale (CD-RISC), and the Symptom Checklist 90 (SCL-90). Structural equation modeling (SEM) was used to reveal the link between childhood maltreatment, coping style, resilience, and mental health symptomology. Results: The results showe that childhood maltreatment was significantly positively correlated with mental health symptomology and significantly negatively correlated with coping style and resilience. Coping style was significantly negatively correlated with mental health symptomology and significantly positively correlated with resilience. Resilience was significantly negatively correlated with mental health symptomology. Coping style and resilience played a partially mediating role in the relationship between childhood maltreatment and college students’ mental health symptomology. Through a chain of intermediary effects on coping style and resilience, childhood maltreatment not only had a direct impact on mental health symptomology but also had an indirect impact. Conclusion: Childhood maltreatment could affect college students’ mental health symptomology through the chain mediating effect of coping style and resilience. Therefore, it is an effective way to reduce the influence of childhood maltreatment on mental health symptomology through some intervention measures to cultivate positive coping style and improve resilience.

How childhood maltreatment links to labor values? The mediating role of moral competence and prosocial normative tendency

BackgroundLabor values are important components of the individual value system and considered to be among the most important values of an individual, especially in China. In studies of values, childhood maltreatment is considered to have an important influence on the formation of individual values. However, there is no previous research about the relationship between childhood maltreatment and labor values. The mechanism of childhood maltreatment on labor values is not clear and requires further study.MethodsThis study intended to investigate the relationship between childhood maltreatment and labor values, and further verify whether moral competence or prosocial normative tendency mediated this correlation. Therefore, 2691 participants were recruited from primary and secondary schools, who completed Labor Values Scale, Childhood Trauma Questionnaire, Moral Competence subscale and Prosocial Norms subscale.ResultsResults revealed the negative correlation between childhood maltreatment and labor values. Importantly, childhood maltreatment also indirectly impacted labor values through moral competence and prosocial normative tendency. It indicated that both moral competence and prosocial normative tendency played a significant mediating role in this relationship. Our findings are valuable for understanding the underlying mechanism between early trauma and values.ConclusionsChildhood maltreatment has important implications for labor values. Moral competence and prosocial normative tendency mediate between childhood maltreatment and labor values. The results remind us to pay attention to the important influence of childhood maltreatment in the cultivation of labor values, and focus on the role of moral competence and prosocial normative tendency.

Characteristics and Mediating Effect of Gut Microbiota With Experience of Childhood Maltreatment in Major Depressive Disorder.

Gut microbiota and childhood maltreatment are closely related to depressive symptoms. This study aimed to analyze the characteristics of gut microbiota in major depressive disorder (MDD) patients with childhood maltreatment experience and explore the correlation between gut microbiota, childhood maltreatment, and depressive symptoms. A total of 37 healthy controls (HCs) and 53 patients with MDD were enrolled, including 18 MDD patients without childhood maltreatment experience and 35 MDD patients with childhood maltreatment experience. The Hamilton’s Depression Scale (HAMD-24) and Childhood Trauma Questionnaire-Short Form (CTQ-SF) were used to evaluate their depressive symptoms and childhood maltreatment experience, respectively. The composition of gut microbiota was evaluated using 16S rRNA sequencing. Spearman’s correlation analysis was used to evaluate the correlation between different gut microbiota, depressive symptoms and childhood maltreatment. The mediation analysis was used to evaluate the mediating effect of gut microbiota. In the α-diversity analysis, we found that the Simpson index and Pielou’s Evenness index differed significantly between MDD patients without childhood maltreatment experience and HCs. In the β-diversity analysis, principal coordinate analysis (PCoA) showed significant differences between MDD patients without childhood maltreatment experience, MDD patients with childhood maltreatment experience and HCs. Twenty-seven different bacteria were identified through Linear discriminant analysis effect size (LEfSe) analysis at different levels of classification. The analysis of the correlation showed that Blautia, Bifidobacterium, Bacteroides, Roseburia, and Phascolarctobacterium were significantly correlated with HAMD and CTQ-SF scores. The mediation analysis showed that childhood maltreatment had a significant direct effect on the patients’ depressive symptoms, and Blautia, Bifidobacterium, Roseburia had a significant mediating effect. The findings of this study suggested that MDD patients with childhood maltreatment experience had different gut microbiota, which might have a mediating effect on the influence of childhood maltreatment on depressive symptoms.

Influence of childhood maltreatment on prevalence, onset, and persistence of psychiatric comorbidities and suicide attempts in bipolar disorders.

Psychiatric comorbidities and suicide attempts are highly prevalent in Bipolar Disorders (BD). We examined the associations between childhood maltreatment, psychiatric comorbidities, and suicide attempts, in terms of lifetime prevalence, sequence of onset, and current symptoms. We assessed 3,047 individuals with BD for suicide attempts, anxiety disorders, substance use disorders, and eating disorders. Participants completed a self-report for the assessment of childhood maltreatment. Associations between childhood maltreatment and characteristics of comorbidities (lifetime prevalence, current symptoms, and age at onset) were examined using logistic regressions and network analyses. Psychiatric comorbidities were frequent with a mean number per individual of 1.23 (SD=1.4). Most comorbidities occurred prior to the onset of BD. Participants who reported higher levels of childhood maltreatment had more frequent and multiple comorbidities, which were also more currently active at inclusion. Childhood maltreatment did not decrease the age of onset of comorbidities, but was associated with a faster accumulation of comorbidities prior to the onset of BD. Logistic regression and network analyses showed that emotional abuse and sexual abuse might play a prominent role in the lifetime prevalence of psychiatric comorbidities and suicide attempts. Childhood maltreatment was associated with suicide attempts, and with frequent, multiple, and persistent psychiatric comorbidities that accumulated more rapidly prior to the onset of BD. Hence, childhood maltreatment should be systematically assessed in individuals with BD, in particular when the course of the disorder is characterized by a high comorbid profile or by a high suicidality.

The Long Arm of Child Maltreatment and Mental Health in Later Life: The Effects of Maltreatment and Family Context?

Purpose. This article examines the role of family context in shaping the influence of childhood maltreatment on later life psychological well-being in the cultural context of Chinese society. Method. Data were drawn from the China Health and Retirement Longitudinal Study (CHARLS) baseline. Maltreatment was measured by corporal punishment by either mother or father in childhood. We used family violence, parents’ family socioeconomic status (SES) and mental health to represent family context. Result. Our ordinary least square regression analysis shows that corporal punishment administered by a mother was associated with higher depressive symptoms (b=0.308, p<0.05) in later life while being hit by father did not result in higher depressive symptoms. Family contexts had residual (“long arm”) influence on respondents’ mental health: violence in the family, including being hit by siblings (b=0.657, p<0.001) and witnessing violence between parents (b=0.658, p<0.001) contributed significantly to higher depressive symptoms. Conclusion. Corporal punishment by parents had long term effects on mental health of their children in later life. Cultural values, such as filial piety did not eliminate the negative impacts of being hit in childhood on mental health in later life. Family contexts including violence between parents also played important roles in shaping the relationship between child maltreatment and mental health in later life. Implication. Our study offers important insights about the complex matrix of cultural traditions, social circumstances and diversity in dealing with child rearing stress and their consequences for later life mental health.

Secretory IgA reactivity to acute psychosocial stress in children and adolescents: the influence of childhood maltreatment and psychopthology

Secretory immunoglobulin A (sIgA) has been proposed as a biomarker of stress-related psychopathology (PP), although it remains poorly studied in youth. The present study investigated sIgA acute psychosocial stress (APS) reactivity in children and adolescent and possible s-IgA alterations associated with childhood maltreatment (CM) and PP. 93 youth (7-17 years) were recruited in the EPI young stress project. To explore sIgA variability, participants gave five saliva samples during Trier Social Stress Test for Children (TSST-C). CM was evaluated following TASSCV criteria, PP via K-SDADS-PL and pubertal development by Tanner stage. We observed sIgA fluctuations indicating the validity of TSST-C to stimulate sIgA secretion (F=4.061,p=.004). Although sIgA trajectories followed a reactivity and recovery pattern in adolescents (F=2.552,p=.042) these responses were blunted in children. No global interaction were found between sIgA and CM or PP. Our findings suggest that APS stimulates sIgA secretion, but only after puberty, and it seems to be non-affected by CM or PP. However, further studies are needed to clarify the validity of IgA as a biomarker including additional measures immediately after APS.

Neuroanatomical changes associated with conduct disorder in boys: influence of childhood maltreatment

Childhood maltreatment (CM) poses a serious risk to the physical, emotional and psychological well-being of children, and can advance the development of maladaptive behaviors, including conduct disorder (CD). CD involves repetitive, persistent violations of others' basic rights and societal norms. Little is known about whether and how CM influences the neural mechanisms underlying CD, and CD-characteristic neuroanatomical changes have not yet been defined in a structural magnetic resonance imaging (sMRI) study. Here, we used voxel-based morphometry (VBM) and surface-based morphometry (SBM) to investigate the influence of the CD diagnosis and CM on the brain in 96 boys diagnosed with CD (62 with CM) and 86 typically developing (TD) boys (46 with CM). The participants were 12-17years of age. Compared to the CM- CD group, the CM+ CD group had structural gray matter (GM) alterations in the fronto-limbic regions, including the left amygdala, right posterior cingulate cortex (PCC), right putamen, right dorsolateral prefrontal cortex (dlPFC) and right anterior cingulate cortex (ACC). We also found boys with CD exhibited increased GM volume in bilateral dorsomedial prefrontal cortex (dmPFC), as well as decreased GM volume and decreased gyrification in the left superior temporal gyrus (STG) relative to TD boys. Regional GM volume correlated with aggression and conduct problem severity in the CD group, suggesting that the GM changes may contribute to increased aggression and conduct problems in boys with CD who have suffered CM. In conclusion, these results demonstrate previously unreported CM-associated distinct brain structural changes among CD-diagnosed boys.

Structural equation modeling approach to explore the influence of childhood maltreatment in adults.

BackgroundChildhood maltreatment affects social functioning in the general adult population. However, how child abuse affects functional disability in adulthood remains unknown. Thus, we investigated the correlation between child abuse, depressive symptoms, cognitive complaints, and functional disability in adult community volunteers.MethodsParticipants (N = 556) completed the Child Abuse and Trauma Scale, Patient Health Questionnaire-9, Cognitive Complaints in Bipolar Disorder Rating Assessment, and Sheehan Disability Scale. Multiple regression analyses and structural equation modeling were performed to evaluate scale correlations.ResultsStructural equation modeling showed that the direct effect of childhood maltreatment on depressive symptoms, the indirect effect of childhood maltreatment on cognitive function via depressive symptoms, and the indirect effects of childhood maltreatment on functional disability via depressive symptoms and via cognitive function were all significant. The direct effects of childhood maltreatment on cognitive function and functional disability were not significant. There was no significant association between variables.LimitationsCross-sectional designs cannot identify causal relationships between parameters. Participants were adult volunteers from the community; therefore, results may not be generalizable to individuals with psychiatric disorders. Sociodemographic variability was a limitation because we used self-reported childhood maltreatment.ConclusionsChildhood maltreatment indirectly affects functional disability via depressive symptoms and via cognitive function through depressive symptoms. We suggest that depressive symptoms and cognitive function play crucial roles in the influence of childhood maltreatment on functional disability in adult community volunteers.

Childhood maltreatment and disordered gambling in adulthood: disentangling causal and familial influences.

Despite abundant research on the potential causal influence of childhood maltreatment (CM) on psychological maladaptation in adulthood, almost none has implemented the discordant twin design as a means of examining the role of such experiences in later disordered gambling (DG) while accounting for genetic and family environmental confounds. The present study implemented such an approach to disentangle the potential causal and familial factors that may account for the association between CM and DG. Participants were 3750 twins from the Australian Twin Registry [Mage = 37.60 (s.d. = 2.31); 58% female]. CM and DG were assessed separately via two semi-structured telephone interviews. Random-intercept generalized linear mixed models were fit to the data; zygosity, sex, educational attainment, childhood psychiatric disorder, adult antisocial behavior, and alcohol use disorder (AUD) were included as covariates. Neither quasi-causal nor familial effects of CM predicted DG after adjusting for covariates. Educational attainment appeared to reduce the risk of DG while AUD appeared to increase risk; evidence also emerged for familial effects of antisocial behavior on DG. Post-hoc analyses revealed a familial effect of CM on antisocial behavior, indicating that the association between CM and DG identified in unadjusted models and in prior studies may be accounted for by genetic and shared family environmental effects of antisociality. These findings add to the meager literature showing that CM does not exert a causal effect on DG, and present novel evidence that familial effects of antisocial behavior may account for the association between CM and DG identified in extant non-twin research.

Childhood maltreatment, serotonin transporter gene, and risk for callous and unemotional traits: A prospective investigation

Previous studies have reported associations between the serotonin transporter 5-HTTLPR genotype and antisocial and aggressive traits and between child maltreatment and antisocial traits. However, few studies have examined whether 5-HTTLPR moderates the influence of childhood maltreatment on callous and unemotional traits, a hallmark of psychopathy. Using a prospective cohort design, children with documented cases of maltreatment and matched controls were followed up and interviewed in adulthood. DNA was extracted from blood and saliva (N = 414) and callous-unemotional (CU) traits were assessed. Childhood maltreatment predicted higher CU scores in adulthood, whereas the effect of 5-HTTLPR was not significant. The effect of child maltreatment on CU traits did not differ by genetic risk (high or low activity 5-HTTLPR), whereas controls with the LL genotype had higher CU scores than controls with the SS genotype. Similar results were found for females and White, non-Hispanics, but not for males and Blacks. Variations in 5-HTTLPR did not affect the impact of child maltreatment on CU traits in adulthood. Genetic risk had a stronger effect on adults with lower environmental risk (controls). Having a history of child maltreatment or the LL genotype placed participants at risk for higher levels of callous and unemotional trait scores.

Childhood maltreatment and life satisfaction in adulthood: The mediating effect of emotional intelligence, positive affect and negative affect.

This study explored the mediation role of emotional intelligence, positive affect, and negative affect in the influence of childhood maltreatment on life satisfaction. A total of 811 participants completed the Childhood Trauma Questionnaire, the Wong Law Emotional Intelligence Scale, the Positive Affect and Negative Affect Scale, and the Satisfaction with Life Scale validly. Results revealed that emotional intelligence, positive affect and negative affect are mediators between childhood maltreatment and life satisfaction. In addition, childhood maltreatment influenced life satisfaction through the sequential intermediary of "emotional intelligence-positive affect" and "emotional intelligence-negative affect". Theoretical and practical implications are discussed.

Influence of Childhood Maltreatment, Adulthood Stressful Life Events, and Affective Temperaments on Premenstrual Mental Symptoms of Nonclinical Adult Volunteers.

BackgroundPrevious studies have shown that childhood maltreatment is associated with premenstrual dysphoric disorder (PMDD). In this study we analyzed how multiple factors, such as childhood maltreatment, affective temperaments, and adult life events influence the severity of premenstrual mental (PMM) symptoms in nonclinical adult volunteers from the community.MethodsA total of 204 participants were recruited and administered the following self-administered questionnaire surveys: PMDD scale, visual analogue scale, Patient Health Questionnaire-9, Life Experience Survey, Temperament Evaluation of Memphis, Pisa, Paris, and San Diego autoquestionnaire version, and the Child Abuse and Trauma scale. In addition to single and multiple regression analyses, structural equation modeling was used for the statistical analyses.ResultsA history of neglect indirectly predicted PMM symptoms through affective temperaments in nonclinical adult volunteers. Three affective temperaments (irritable, cyclothymic, and anxious) directly predicted PMM symptoms.ConclusionThis study is the first to report that childhood maltreatment, particularly neglect, indirectly predicted PMM symptoms through affective temperaments. The results of our study suggest that affective temperament is a mediator of the influence of childhood maltreatment on PMM symptoms.

How Childhood Maltreatment Impacts Aggression from Perspectives of Social Comparison and Resilience Framework Theory

ABSTRACT The current study explored internal mechanisms by which childhood maltreatment influenced aggression from perspectives of social comparison theory and resilience framework theory for the first time. Authors randomly recruited 811 participants and asked them to complete Childhood Trauma Questionnaire (CTQ), Dispositional Envy Scale (DES), Connor–Davidson Resilience Scale (CD-RISC) and Aggression Questionnaire (AQ). Finally, the data were analyzed by structural equation model method. The results showed that envy and resilience were both important mediating mechanisms between childhood maltreatment and aggression, and childhood maltreatment could affect envy through resilience and then influenced aggression. The present findings provide important practical guidance for how to effectively inhibit the influence of childhood maltreatment on aggression.
