Childhood maltreatment is associated with depression but not with hypochondriasis in later life

Examining associations between early adverse life events and health anxiety using the DanFund study

Childhood adverse life events, in particular illness-related events, have been proposed as a risk factor for development of health anxiety.

OBJECTIVE

To examine: 1) The association between accumulated early adverse life events and health anxiety in adulthood and 2) The influence of specific types of life events, i.e., illness, injury, loss, and the impact of their exposure time on health anxiety in adulthood.

METHOD

A population-based, cross-sectional study including 7454 participants from the Danish study of Functional Disorders (DanFunD). Health anxiety was assessed with Whiteley-6-R and early adverse life events with the Cumulative Lifetime Adversity Measure. Caseness was defined as a Whiteley-6-R score ≥ 90%ile. Generalised linear models were used to estimate the association with relative risk (RRa, adjusted for sociodemographics).

RESULTS

A cumulative effect was found for each additional adverse life event with 8.03% increased risk of health anxiety. Two categories were associated with a higher risk: violence (RRa = 1.65, 95% CI: 1.37-1.99, P < 0.001) and relationship stress (RRa = 1.34; 95% CI: 1.15-1.57, P < 0.001). Respondents with self-reported childhood illness were also more likely to report health anxiety (RRa = 1.52, 95% CI 1.11-2.09, P = 0.009). Timewise, health anxiety seemed associated with illness during school age and injury during adolescence.

CONCLUSIONS

Accumulated adverse life events, early exposure to specific categories and specific health-related life events were associated with self-reported health anxiety in adulthood. Our findings provide new knowledge on the potential role of early life events in health anxiety which could inform early intervention.

A Meta-Analysis of the Effects of Childhood Maltreatment on Elderly Depression

Background: The present study aimed to synthesize the effects of five types of child maltreatment (physical abuse, emotional abuse, sexual abuse, physical neglect and emotional neglect) on late-life depression.Method: Four English-language databases (Web of Science, PsycINFO and PsycARTICLES, PubMed, and Cochrane Library) and three Chinese databases (China National Knowledge Infrastructure, Wanfang Database, and Weipu Database) were systematically reviewed, and data related to the association between child maltreatment and late-life depression were extracted. Ten studies involving 30,308 older adults were included, and the effect sizes were pooled using random-effect models.Findings: Except for sexual abuse, four types of child maltreatment were found to be positively associated with late-life depression. Physical abuse, emotional abuse and physical neglect were associated with elderly depression (PA: OR = 1.73, 95% CI = 1.55-1.95, p < .001; EA: OR = 1.92, 95% CI = 1.73-2.12, p < .001; PN: OR = 2.05, 95% CI = 1.15-3.67, p < .01) at a small level, and emotional neglect was associated with elderly depression (OR = 3.25, 95% CI = 1.43-7.39, p < .001) at an approximately moderate level. Gender moderated the relationship between physical neglect, emotional neglect, and late-life depression.Conclusion: Our findings highlight the significance of child maltreatment in the development of late-life depression, and underscore the need for future research and practice to explore potential ways to address late-life depression among older adults who suffered child maltreatment.

The role of only-child status in the effect of childhood trauma and parental rearing style on depressive symptoms in Shanghai adolescents

INTRODUCTION

After decades of the one-child policy, China changed its rules to allow two children in 2016, which altered family dynamics. Few studies have examined the emotional problems and the family environment of multi-child adolescents. This study aims to explore the role of only-child status in the impact of childhood trauma and parental rearing style on depressive symptoms of adolescents in Shanghai, China.

METHODS

A cross-sectional study was conducted on 4,576 adolescents (M = 13.42 years, SD = 1.21) from seven middle schools in Shanghai, China. Childhood Trauma Questionnaire-Short Form, the Short Egna Minnen Beträffande Uppfostran, and Children's Depression Inventory were used to evaluate childhood trauma, perceived parental rearing style, and depressive symptoms of adolescents, respectively.

RESULTS

Results showed that girls and non-only children reported more depressive symptoms, while boys and non-only children perceived more childhood trauma and negative rearing styles. Emotional abuse, emotional neglect, and father's emotional warmth significantly predicted depressive symptoms in both only children and non-only children. Father's rejection and mother's overprotection were related to adolescents' depressive symptoms in only-child families, but not non-only child families.

DISCUSSION

Therefore, depressive symptoms, childhood trauma, and perceived negative rearing styles were more prevalent among adolescents in non-only child families, while negative rearing styles were especially associated with depressive symptoms in only children. These findings suggest that parents pay attention to their impacts on only children and give more emotional care to non-only children.

Adverse childhood experiences in patients with severe health anxiety: No evidence for an increased frequency compared to patients with obsessive-compulsive disorder

Theoretical models of health anxiety emphasize adverse childhood experiences in the development of the disorder, but few studies examine such events in patients with severe health anxiety and the results are difficult to compare across studies. The present study examined adult retrospective reports of illness-related and traumatic childhood experiences in 31 patients with severe health anxiety, 32 non-clinical control participants, and a clinical control group of 33 patients with obsessive-compulsive disorder. No evidence of an increased frequency of adverse childhood experiences in patients with severe health anxiety was found. However, patients with severe health anxiety who had experienced the death of a friend or family member or a major upheaval during childhood, perceived these events as having been more traumatic than the control participants. These findings suggest that biases in how adverse childhood experiences are interpreted or remembered might play a role in severe health anxiety. The findings are discussed in relation to the cognitive behavioral model of health anxiety, and some of the processes in interpretation and memory that could explain how adverse childhood experiences might play a role in the development and maintenance of severe health anxiety are outlined.

A Half Century of Research on Childhood and Adolescent Depression: Science Mapping the Literature, 1970 to 2019

In order to gain an in-depth understanding of research about childhood and adolescent depression, this article analyzes the scale, development, and geographic distribution of the literature in the field based on 8491 articles extracted from the Web of Science Core database. Using citation analysis, this article identifies influential journals, scholars, and documents in this field. The study found that in the past 15 years, the number of documents has increased significantly and geographical diversity has also increased. Most of the highly influential literature relates to depression inventories. Using keyword co-occurrence analysis, this article also identified three key research topics focusing on (a) child and adolescent depression symptoms and prevalence, (b) parental depression and child behavioral or emotional problems, and (c) childhood abuse and depression. This study uses 'science mapping' as a means to provide a better understanding of research trends about childhood and adolescent depression that have emerged over the past half century, and may serve as reference for future research.

Validation and Adaptation of the Slovak Version of the Childhood Trauma Questionnaire (CTQ)

Background: Previous research has shown a strong relationship between childhood trauma and worsened physical and mental health. The Childhood Trauma Questionnaire (CTQ) is a commonly used tool assessing early traumatic experiences. The aim of this study was to verify the psychometric properties of the Slovak version of the CTQ. Methods: Data were collected on a representative Slovak sample (N = 1018, mean age 46.24 years, 48.7% of men). The dimensional structure of the CTQ was tested by confirmatory factor analysis (CFA); convergent validity was assessed using the Adverse Childhood Questionnaire (ACE-IQ). Results: CFA confirmed the standard 5-factor CTQ model. The subscales of the CTQ and the ACE-IQ questionnaires showed moderate to high correlations. The internal consistency of the scale was found to be acceptable. Emotional neglect (EN) was reported in 48.1%, physical neglect (PN) in 35.8%, emotional abuse in 15.8%, physical abuse (PA) in 11.0%, and sexual abuse (SA) in 9.1% of the Slovak population, according to the scoring, when even low abuse or neglect is assessed as trauma. Conclusion: The CTQ questionnaire fulfilled the validation criteria and appeared to be a suitable method for assessing retrospectively reported childhood trauma experiences in the Slovak population.

COVID-19-related fear and stress among individuals who experienced child abuse: The mediating effect of complex posttraumatic stress disorder

BACKGROUND

The COVID-19 pandemic exposes individuals not only to health-related risks, but also to psychosocial fear and acute stress. Previous studies reveal that individuals who experienced child abuse (CA), especially those who suffer from complex posttraumatic stress disorder (CPTSD), are at a higher risk of reacting with fear and stress when faced with stressful life-events.

OBJECTIVE

To test whether exposure to CA is implicated in a higher risk of COVID-19-related fear and acute stress, and whether CPTSD intervenes in such processes.

PARTICIPANTS AND SETTINGS

A convenience sample of 837 adults participated in the study during the first peak of COVID-19 in Israel.

METHODS

Participants completed self-report questionnaires, assessing child physical, sexual and emotional abuse, CPTSD (ITQ), COVID-19-related acute stress disorder (COVID-19 ASD; ASDS) and fear of COVID-19.

RESULTS

Bivariate analyses showed that participants who experienced CA were higher than participants who did not experience CA in COVID-19 ASD (p = .032), but not in fear of COVID-19 (p = .65). Mediation analyses demonstrated two significant paths: in the first, CA was associated with elevated fear of COVID-19 (effect = .061, .059; p < 0.05) and COVID-19 ASD (effect = .14, .084; p < 0.05) through the mediation of CPTSD; in the second path, when controlling for the mediation of CPTSD, CA was associated with reduced fear of COVID-19 (effect = -.15; p = 0.001), and COVID-19 ASD (effect = -.12; p = 0.024).

CONCLUSIONS

The findings reveal a complex pattern, indicating that CPTSD may be a risk factor for elevated levels of COVID-19 distress among individuals who experienced CA. However, some CA survivors may express reduced COVID-19 distress.

Child maltreatment and depression: A meta-analysis of studies using the Childhood Trauma Questionnaire

BACKGROUND

Researchers have documented that child maltreatment is associated with adverse long-term consequences for mental health, including increased risk for depression. Attempts to conduct meta-analyses of the association between different forms of child maltreatment and depressive symptomatology in adulthood, however, have been limited by the wide range of definitions of child maltreatment in the literature.

OBJECTIVE

We sought to meta-analyze a single, widely-used dimensional measure of child maltreatment, the Childhood Trauma Questionnaire, with respect to depression diagnosis and symptom scores.

PARTICIPANTS AND SETTING

192 unique samples consisting of 68,830 individuals.

METHODS

We explored the association between total scores and scores from specific forms of child maltreatment (i.e., emotional abuse, physical abuse, sexual abuse, emotional neglect, and physical neglect) and depression using a random-effects meta-analysis.

RESULTS

We found that higher child maltreatment scores were associated with a diagnosis of depression (g = 1.07; 95 % CI, 0.95-1.19) and with higher depression symptom scores (Z = .35; 95 % CI, .32-.38). Moreover, although each type of child maltreatment was positively associated with depression diagnosis and scores, there was variability in the size of the effects, with emotional abuse and emotional neglect demonstrating the strongest associations.

CONCLUSIONS

These analyses provide important evidence of the link between child maltreatment and depression, and highlight the particularly larger association with emotional maltreatment in childhood.

Relationship between adverse childhood experiences and illness anxiety in irritable bowel syndrome - The impact of gender

OBJECTIVE

Irritable bowel syndrome (IBS) is a functional disorder with a complex biopsychosocial etiopathogenesis. Various psychosocial factors like adverse childhood experiences (ACE) and illness anxiety appear to be relevant, but underlying mechanisms are still not fully understood. Furthermore, there are indicators of gender specific effects of ACE on IBS. Therefore, this study analyzed group differences between IBS patients and healthy controls (HCs) according to ACE and illness anxiety, and the relationship between ACE and illness anxiety by taking gender differences into consideration.

METHODS

A cross-sectional multi-center study was conducted comparing IBS patients with HCs. Illness anxiety was recorded using the Whiteley-Index-7, childhood adversities via the 10-item Adverse-Childhood-Experiences-score, anxiety by the Generalized Anxiety Disorder seven-item questionnaire and depressive symptoms using the nine-item depression module of the patient-health-questionnaire. Group differences between IBS patients and HCs were analyzed and correlation analyses were performed.

RESULTS

Overall, 127 gender and education matched participants per group were included. Compared to HCs, IBS patients were characterized by higher prevalences for adverse childhood experiences (63.8% vs. 48.0%, p = .02, OR = 1.33) and increased levels of illness anxiety (p < .001, η² = 0.595). Taking into account gender specific effects, there was a significant correlation between adverse childhood experiences and illness anxiety in female IBS patients, but not in male (r = 0.242, p = .03 vs. r = 0.162, p = .29). However, after controlling for depression and anxiety, this correlation disappeared.

CONCLUSION

Our findings suggest a possible gender-specific association of ACE with illness anxiety in female IBS patients that might be linked to increased levels of depression and anxiety.

Examining the relationships between childhood abuse history, attachment, and health anxiety

This study examined the relationship between childhood abuse experiences and health anxiety in adulthood and investigated the role of attachment in this relationship. In total, 181 university students (aged 18–29 years) completed a battery of measures that assessed childhood abuse, health anxiety, and attachment orientation. Health anxiety was associated with all categories of childhood abuse and overall childhood abuse severity. Anxious attachment partially mediated the relationship between overall childhood abuse and health anxiety in adulthood. The results further our understanding of the relationship between childhood abuse and health anxiety in adulthood and provide support for the interpersonal model of health anxiety.

Early life exposures, neurodevelopmental disorders, and transposable elements

Transposable elements make up a much larger portion of the genome than protein-coding genes, yet we know relatively little about their function in the human genome. However, we are beginning to more fully understand their role in brain development, neuroinflammation, and adaptation to environmental insults such as stress. For instance, glucocorticoid receptor activation regulates transposable elements in the brain following acute stress. Early life is a period of substantial brain development during which transposable elements play a role. Environmental exposures and experiences during early life that promote abnormal regulation of transposable elements may lead to a cascade of events that ultimately increase susceptibility to disorders later in life. Recent attention to transposable elements in psychiatric illness has begun to clarify associations indicative of dysregulation of different classes of transposable elements in stress-related and neurodevelopmental illness. Though individual susceptibility or resiliency to psychiatric illness has not been explained by traditional genetic studies, the wide inter-individual variability in transposable element composition in the human genome make TEs attractive candidates to elucidate this differential susceptibility. In this review, we discuss evidence that regulation of transposable elements in the brain are stage-specific, sensitive to environmental factors, and may be impacted by early life perturbations. We further present evidence of associations with stress-related and neurodevelopmental psychiatric illness from a developmental perspective.

Emotion dysregulation in hypochondriasis and depression

BACKGROUND

The aim of this study was to explore whether certain aspects of emotion dysregulation (i.e., facets of alexithymia and rumination) are more closely linked to hypochondriasis than to depression and vice versa.

METHODS

Nineteen patients with hypochondriasis (HYP), 33 patients with depression, and 52 healthy control participants completed the Toronto Alexithymia Scale, the Response Styles Questionnaire, and additional symptom and illness behaviour scales. A clinical interview was used to establish DSM-IV diagnoses and to exclude all cases with more than one axis I diagnosis.

RESULTS

Depression patients reported more difficulties describing feelings and more symptom- and self-focused rumination than both HYP patients and healthy individuals, whereas HYP patients differed only from healthy individuals in regard to more difficulties in identifying feelings and more symptom-focused rumination. Multiple regression analyses, including all assessed facets of emotion dysregulation, showed that the degree of somatoform features (somatic symptoms, health anxiety, and illness behaviour) was specifically predicted by higher difficulties in identifying feelings scores, whereas depressive symptom levels were specifically predicted by higher rumination scores.

CONCLUSIONS

Specific associations were found between difficulties in identifying feelings and key features of HYP, whereas depression was linked to a more generalized pattern of emotion regulation deficits.

KEY PRACTITIONER MESSAGE

Emotion dysregulation can be found in hypochondriasis and depression Difficulties in identifying own feelings are specifically linked to somatic symptoms, health anxiety, and illness behaviour, whereas a more generalized pattern of emotion dysregulation is found in relation to depression Further research is needed to investigate whether the effectiveness of current treatments for depression, hypochondriasis, health anxiety, and related disorders could be improved by additional emotion regulation interventions.

The role of childhood trauma, early maladaptive schemas, emotional schemas and experimental avoidance on depression: A structural equation modeling

The present investigation was designed to examine disconnection and rejection (DR) schemas, negative emotional schemas (NESs) and experimental avoidance (EA) as mediating variables of the relationship between the childhood trauma (CT) and depression. Specifically we examined the mediating role of NESs and EA between DR schemas and depression. The study sample consist of 439 female college students (M_age=22.47; SD=6.0), of whom 88 met the criteria for current major depressive disorder (MDD) and 351 who had history of MDD in the last 12 months. Subjects were assessed by Structured Clinical Interview for DSM-IV (SCID) and completed the Childhood Trauma Questionnaire (CTQ), the Early Maladaptive Schemas Questionnaire (SQ-SF), the Leahy Emotional Schemas Scale (LESS), the Acceptance and Action Questionnaire (AAQ-II), and the Beck Depression Inventory-II (BDI-II). The findings showed that DR schemas were mediator of the relationship CT and depression but CT through the NESs and EA did not predict depression. NESs were mediator of the relationship between DR schemas and depression and EA was mediator of the relationship between DR schemas and depression. In general, results suggest that intervention of depressed women may need to target the changing of DR schemas, NESs and reduction of EA.

Posttraumatic Stress Disorder: Does the Gut Microbiome Hold the Key?

Gut bacteria strongly influence our metabolic, endocrine, immune, and both peripheral and central nervous systems. Microbiota do this directly and indirectly through their components, shed and secreted, ranging from fermented and digested dietary and host products to functionally active neurotransmitters including serotonin, dopamine, and γ-aminobutyric acid. Depression has been associated with enhanced levels of proinflammatory biomarkers and abnormal responses to stress. Posttraumatic stress disorder (PTSD) appears to be marked in addition by low cortisol responses, and these factors seem to predict and predispose individuals to develop PTSD after a traumatic event. Dysregulation of the immune system and of the hypothalamic-pituitary-adrenal axis observed in PTSD may reflect prior trauma exposure, especially early in life. Early life, including the prenatal period, is a critical time in rodents, and may well be for humans, for the functional and structural development of the immune and nervous systems. These, in turn, are likely shaped and programmed by gut and possibly other bacteria. Recent experimental and clinical data converge on the hypothesis that imbalanced gut microbiota in early life may have long-lasting immune and other physiologic effects that make individuals more susceptible to develop PTSD after a traumatic event and contribute to the disorder. This suggests that it may be possible to target abnormalities in these systems by manipulation of certain gut bacterial communities directly through supplementation or indirectly by dietary and other novel approaches.

Personality features, dissociation, self-stigma, hope, and the complex treatment of depressive disorder

OBJECTIVE

Identifying the predictors of response to psychiatric and psychotherapeutic treatments may be useful for increasing treatment efficacy in pharmacoresistant depressive patients. The goal of this study was to examine the influence of dissociation, hope, personality trait, and selected demographic factors in treatment response of this group of patients.

METHODS

Pharmacoresistant depressive inpatients were enrolled in the study. All patients completed Clinical Global Impression - both objective and subjective form (CGI), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI) at baseline and after 6 weeks of combined pharmacotherapy and psychotherapy (group cognitive-behavioral or group psychodynamic) treatment as an outcome measures. The Internalized Stigma of Mental Illness Scale (ISMI), Dissociative Experience Scale (DES), Adult Dispositional Hope Scale (ADHS), and Temperament and Character Inventory (TCI-R) were completed at the start of the treatment with the intention to find the predictors of treatment efficacy.

RESULTS

The study included 72 patients who were hospitalized for the pharmacoresistant major depression; 63 of them completed the study. The mean scores of BDI-II, BAI, subjCGI, and objCGI significantly decreased during the treatment. BDI-II relative change statistically significantly correlated with the total ISMI score, Discrimination Experience (ISMI subscale), and Harm Avoidance (TCI-R personality trait). According to stepwise regression, the strongest factors connected to BDI-II relative change were the duration of the disorder and Discrimination Experience (domain of ISMI). ObjCGI relative change significantly correlated with the level of dissociation (DES), the total ISMI score, hope in ADHS total score, and Self-Directedness (TCI-R). According to stepwise regression, the strongest factor connected to objCGI relative change was Discrimination Experience (domain of ISMI). The existence of comorbid personality disorder did not influence the treatment response.

CONCLUSION

According to the results of the present study, patients with pharmacoresistant depressive disorders, who have had more experience with discrimination because of their mental struggles, showed a poorer response to treatment.

Relationship between dysfunctional attitudes and childhood traumas in women with depression

AIM

Psychological traumas in childhood could lead to dysfunctional attitudes causing negative cognitive structuring and mistakes in data processing. In this study, we aimed to research the relation of childhood traumas with dysfunctional attitudes in female patients with depressive disorder.

METHOD

Seventy female patients diagnosed with depressive disorder and 50 healthy volunteers participated in the study, and the participants were administered a socio-demographic form, the Beck Depression Inventory (BDI), the Childhood Trauma Questionnaire (CTQ) and the Dysfunctional Attitudes Scale (DAS).

RESULTS

Comparing the two groups by median values of CTQ, total CTQ, sexual abuse, physical abuse, emotional abuse, physical neglect and emotional neglect, median values of the patient group were significantly higher compared to the control group, and comparison by median values of DAS revealed that median values of the patient group was significantly lower compared to the control group. In the correlation analysis carried out for finding the relation between CTQ and DAS, there was a significant negative correlation between DAS score and emotional abuse score. In the patient group, all kinds of abuses and neglects except for sexual abuse were at a higher rate in those with a history of depression in the family.

CONCLUSION

In our study, a negative correlation was determined between DAS and only emotional abuse leading us to the finding that one of the factors mediating childhood traumas to cause depression could lead to dysfunctional attitudes.

Inflammation and neuronal plasticity: a link between childhood trauma and depression pathogenesis

During the past two decades, there has been increasing interest in understanding and characterizing the role of inflammation in major depressive disorder (MDD). Indeed, several are the evidences linking alterations in the inflammatory system to Major Depression, including the presence of elevated levels of pro-inflammatory cytokines, together with other mediators of inflammation. However, it is still not clear whether inflammation represents a cause or whether other factors related to depression result in these immunological effects. Regardless, exposure to early life stressful events, which represent a vulnerability factor for the development of psychiatric disorders, act through the modulation of inflammatory responses, but also of neuroplastic mechanisms over the entire life span. Indeed, early life stressful events can cause, possibly through epigenetic changes that persist over time, up to adulthood. Such alterations may concur to increase the vulnerability to develop psychopathologies. In this review we will discuss the role of inflammation and neuronal plasticity as relevant processes underlying depression development. Moreover, we will discuss the role of epigenetics in inducing alterations in inflammation-immune systems as well as dysfunction in neuronal plasticity, thus contributing to the long-lasting negative effects of stressful life events early in life and the consequent enhanced risk for depression. Finally we will provide an overview on the potential role of inflammatory system to aid diagnosis, predict treatment response, enhance treatment matching, and prevent the onset or relapse of Major Depression.

Childhood adversities and laboratory pain perception

Childhood adversity has frequently been related to a wide range of psychosomatic complaints in adulthood. The present study examined the relationship between different forms of childhood adversity and laboratory measures of pain. Heat pain tolerance and perceived heat pain intensity were measured in a community-based sample of 62 women (aged 20-64 years). Participants completed the Childhood Trauma Questionnaire (CTQ), which assesses five forms of childhood adversity: physical abuse, sexual abuse, emotional abuse, physical neglect, and emotional neglect. Somatic symptoms, depressive symptoms, and pain catastrophizing were assessed as potential mediators. Bivariate analyses indicated that emotional abuse but no other forms of childhood adversity were significantly related to decreased heat pain tolerance (r=-0.27; P<0.05). Accordingly, multiple regression analyses revealed that only emotional abuse was a significant predictor of heat pain tolerance (β=-0.62; P=0.034) when entering all CTQ subscales simultaneously. Although emotional abuse was also related to somatic symptoms, depressive symptoms, and pain catastrophizing, none of these variables mediated the relationship between childhood adversity and laboratory pain (P>0.1). No significant associations were found between any forms of childhood adversity and heat pain intensity. Our findings indicate that the severity of emotional childhood abuse is associated with decreased pain tolerance, an affective component of pain, but not with heat pain intensity, which has been described as a sensory component of pain.
