Childhood maltreatment in patients with somatization disorder

Somatization Mediates the Relationship Between Childhood Trauma and Pain Ratings in Patients with Irritable Bowel Syndrome

GOALS

To identify potential mechanisms by which childhood trauma may lead to the adult development of abdominal symptoms in patients with irritable bowel syndrome (IBS).

BACKGROUND

Patients with IBS frequently report a history of childhood trauma. The pathophysiology by which abdominal pain arises in patients with IBS is multidimensional, consisting of both peripheral factors, such as altered motility, inflammation, and bacterial overgrowth, as well as central factors, such as psychological distress and neuro-hormonal dysregulation.

STUDY

Adult psychological factors (anxiety, depression, and somatization) were examined to determine if they mediate the relationship between retrospective reports of childhood trauma and current adult IBS abdominal symptoms in a study of 436 patients (M age=41.6, 79% F) meeting Rome III diagnosis criteria. Childhood trauma was measured using retrospective questions assessing physical and sexual abuse. Psychological factors in adulthood were measured with the subscales of the Brief Symptom Inventory-18. Outcome variables included adult IBS symptoms of abdominal pain, bloating, and satisfaction with bowel habits from the IBS Symptoms Severity Scale.

RESULTS

Results indicated that somatization mediated the relationship between childhood abuse and abdominal pain and bloating but not bowel satisfaction.

CONCLUSIONS

This study provides insight into the multifactorial nature of IBS-associated abdominal pain in patients with a history of childhood trauma, elucidating the need for a trauma-informed treatment approach for patients with histories of abuse.

A cognitive behavioural group treatment for somatic symptom disorder: a pilot study

BACKGROUND

Somatic symptom disorder (SSD) presents challenges to the healthcare system, including frequent medical visits, lack of symptom relief experienced by individuals with this condition, high associated medical costs, and patient dissatisfaction. This study examined the utility of a novel, low-barrier, brief cognitive behavioural therapy (CBT) group intervention for individuals with SSD.

METHODS

Participants were referred by their mental health providers or self-referral. Each participant underwent a telephone screen and in-person psychological and neuropsychological screen. Two cycles of the CBT-based group (n = 30), each consisting of six weekly two-hour sessions, were facilitated at a large outpatient mental healthcare facility in Ontario, Canada. The final sample consisted of 13 individuals of whom 11 completed the treatment. Clinical outcome measures were administered pre-, mid- and post-group, including the Generalized Anxiety Disorder-7, Perceived Stress Scale-4, Pain Self-Efficacy Questionnaire, Pain Disability Index, Revised Illness Perception Questionnaire, and sections of the Patient Health Questionnaire. Six healthcare utilization metrics were collected from electronic medical records at six months pre- and post-group. Paired samples t-tests were used to examine pre- to post-group differences in participants' somatic symptoms, psychological functioning, health, and degree of healthcare utilization.

RESULTS

When comparing pre- and post- group, we observed reductions in the mean scores for somatic symptom severity, depressive symptomatology, anxiety, perceived stress, and perceived disability related to pain. The change in depressive symptomatology yielded a small effect size (d = 0.30). Further, we observed downward trends across participants' pre- to post-group healthcare utilization, with small effect sizes observed for hospital admission (d = 0.36), days admitted to hospital (d = 0.47), and inpatient consults (d = 0.42). Differences between pre- and post-group measures of somatic symptom severity, psychological functioning, health, or healthcare utilization did not reach significance.

CONCLUSIONS

Current findings provide support for the potential effectiveness of an abbreviated CBT group for individuals with SSD in reducing psychiatric symptomatology. Further research is recommended, including randomized control trials, cost-benefit analyses, and comparisons between abbreviated versus longer-duration treatment programs for SSD.

Families With Violence Exposure and the Intergenerational Transmission of Somatization

INTRODUCTION

Adults who have histories of childhood trauma have been noted to display greater somatization, dissociative symptoms and affect dysregulation. What happens in the parent-child relationship when those traumatized children become parents? A potential link to somatization in the child has been suggested by several prior studies. Children who have early attachment disturbances had more physical complaints if their mothers displayed less maternal sensitivity during observed parent-child interactions. Yet, the intergenerational link between maternal and child somatization has not been sufficiently explored in a longitudinal study in order to understand the potential impact of maternal trauma history and related psychopathology on subsequent child somatization and psychopathology.

METHODS

This paper examined prospective, longitudinal data of 64 mother-toddler dyads (mean age = 2.4 years, SD = 0.7) who were later studied when children had a mean age of 7 years. Mothers with and without histories of interpersonal violence (IPV; physical/sexual abuse and/or family violence exposure) were included. Mothers with IPV histories were oversampled. Linear and Poisson regression models were used to test the associations between maternal IPV-related post-traumatic stress disorder (PTSD) with maternal somatization severity when children were toddlers, and between maternal somatization and maternal interactive behaviors with child somatization by maternal report and clinician-rated assessment at school-age.

RESULTS

Maternal PTSD severity was significantly associated with increased maternal somatization severity (p = 0.031). Maternal somatization severity during the child's early childhood predicted both maternal report of child somatization (p = 0.011) as well as child thought problems (p = 0.007) when children were school-aged. No association was found between maternal somatization and child-reported psychopathology. The study did not find that maternal alexithymia, caregiving behaviors or child exposure to violence contributed significantly to the model examining the association between maternal and child somatization.

CONCLUSION

The results are in line with the hypothesis of intergenerational transmission of somatization in the context of IPV and related maternal PTSD during formative early development. We interpret this as an expression of psychological distress from mother to child, as maternal trauma and pathology affect the caregiving environment and, thus, the parent-child relationship. The authors conclude with a discussion of implications for parent-infant and early childhood intervention.

Simulating the mind and applications – a theory-based chance for understanding psychic transformations in somatic symptom disorders

With the new category of somatic symptom disorder/bodily distress disorder in ICD-11, research into pathogenetic and therapeutic pathways is stimulated. By turning away from the definition of somatoform disorders as “the lack of something physical explaining everything”, this new classification might offer a way to put the focus on the individual patient’s psychodynamic balance and conflicts and their condensation in the symptom. Modelling and simulation have a long history in science to gain insight also into complex phenomena. Considering the evolution of precision medicine many different parameters are meanwhile operationalised and ready for consequent process research. Calculation models have to fit to the complexity of this disorder category. In an interdisciplinary discourse between computer and medical/psychoanalytic scientists a multilayer, fine grained calculation model is elaborated. Starting from a clinical case history, within iterative discussion, by acknowledging the demand for interdisciplinary synergy and cooperation in science, psychoanalytic theory served as the basis for computer-scientific information technique. A parallelisation with the Mealy model helped to establish a meaningful calculation possibility for further process research. How psychic transformations can be understood properly in order to provide meaningful treatments, the respective training, and to conduct appropriate process- and outcome-research is established in simulating the mind and applications.

The association of childhood maltreatment, somatization and health-related quality of life in adult age: Results from a population-based cohort study

BACKGROUND

Population-based data regarding the relationship between childhood maltreatment (CM), somatization and health-related quality of life (HRQoL) in adults are limited.

OBJECTIVE

To investigate the association of CM history (emotional and physical abuse and neglect, sexual abuse) with somatization and with physical and mental HRQoL in adults.

PARTICIPANTS AND SETTING

Data from 2305 participants from the population-based Study of Health in Pomerania were analyzed (aged 20 to 80 years).

METHODS

We applied the Childhood Trauma Questionnaire. Somatoform disorders were diagnosed according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) in a clinical interview. Using a self-administered questionnaire, we assessed the number of somatic symptoms and physical and mental HRQoL.

RESULTS

Sexual abuse was related to the diagnosis of a somatoform disorder (odds ratio [OR] 1.87; 95% confidence interval [CI] 1.29, 2.69). Emotional abuse and physical neglect were associated with the number of somatic symptoms (B = 0.93; 95% CI 0.42, 1.45 and B = 0.50; 95% CI 0.17, 1.83, respectively). Sexual abuse and physical neglect were related to lower physical HRQoL (B = -1.87; 95% CI -3.17, -0.57 and B = -1.26; 95% CI -2.02, -0.49, respectively), and emotional abuse was associated with lower mental HRQoL (B = -2.83; 95% CI -4.03, -1.62).

CONCLUSIONS

A history of CM, in particular sexual abuse, emotional abuse and physical neglect, is a risk factor for somatization and impaired HRQoL in adults. Individuals with somatic symptoms are an important target group for CM screening. Addressing HRQoL might be significant in psychotherapy for individuals with CM experience.

Pathway Linking Different Types of Childhood Trauma to Somatic Symptoms in a Subclinical Sample of Female College Students: The Mediating Role of Experiential Avoidance

ABSTRACT

Research has shown that women are more prone to childhood trauma and this state is associated with somatic symptoms. Also, people who have been exposed to traumatic experiences use experiential avoidance to reduce negative emotions. However, the mediating role of experiential avoidance in the relationship between childhood trauma and somatic symptoms is not clear, so, the present study investigated whether the relationships among different types of childhood trauma and somatic symptoms could be explained by experiential avoidance in female college students. In a cross-sectional study, 251 Iranian female college students with somatic symptoms were recruited from the University of Tabriz. Participants completed self-report scales, including the Persian version of Child Abuse Self-Reported Scale, Acceptance and Action Questionnaire-II (AAQ-II), and the Patient-health questionnaire (PHQ-15). A path analysis was used to empirically explore the relationships. Structural equation modeling analyses confirmed a partial mediation model. Study participants who had a higher level of emotional trauma reported higher levels of somatic symptoms. Emotional and neglect trauma showed significant positive relations with experiential avoidance. Bootstrapping results showed that experiential avoidance partially mediated the relationship between emotional trauma and somatic symptoms. Moreover, the association between neglect and somatic symptoms was fully mediated by experiential avoidance. These findings suggest that experiential avoidance might be one mechanism explaining how adverse emotional and neglect experiences influence somatic symptoms. Interventions addressing experiential avoidance through methods such as emotion-focused therapy and mindfulness are discussed as potential future directions for treating somatic symptoms in females who experienced emotional and neglect trauma.

Unwillingly traumatizing: is there a psycho-traumatologic pathway from general surgery to postoperative maladaptation?

BACKGROUND

Surgery may possibly be undermined by psychologic, psychiatric and psychosomatic problems, as long as these problems interfere with a patient's capacity to cope with surgery adaptively. Recent studies have shown that interpersonal trauma, e.g. abuse or neglect, and its correlates are involved in the adaptation to surgery. This observation is heuristically coherent, given the respective traumatization is an interpersonal event occurring in a relationship. Notably, surgery inevitably leads to the violation of physical boundaries within a doctor-patient relationship. Based on the principles of psycho-traumatologic thinking, such a constellation is deemed qualified to activate posttraumatic symptoms in the traumatized.

METHOD

The present topical review summarizes the respective findings which point to a subgroup of patients undergoing surgery, in whom difficulty bearing tension and confiding in others may cause adaptive problems relevant to surgery. Although this theorizing is empirically substantiated primarily with respect to total knee arthroplasty (TKA), a pubmed-research reveals psychopathologic distress to occur prior to surgery beyond TKA. Likewise, posttraumatic distress occurs in large numbers in the context of several operations, including cardiac, cancer and hernia surgery.

CONCLUSION

Aspects of psychological trauma may be linked to the outcomes of general surgery, as well, e.g. biliary, hernia or appendix surgery. The mechanisms possibly involved in this process are outlined in terms of a hierarchical organization of specific anxiety and negative affect as well as in terms of psychodynamics which imply the unconscious action of psychologic defenses at their core.

IMPLICATIONS

Not least, we encourage the screening for trauma and its correlates including defenses prior to general surgery in order to identify surgical candidates at risk of, e.g. chronic postoperative pain, before the operation.

Briquet syndrome revisited: implications for functional neurological disorder

With the creation of the Somatic Symptom and Related Disorders category of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition in 2013, the functional neurological (symptom) disorder diagnostic criteria underwent transformative changes. These included an emphasis on ‘rule-in’ physical examination signs/semiological features guiding diagnosis and the removal of a required proximal psychological stressor to be linked to symptoms. In addition, the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition somatization disorder, somatoform pain disorder and undifferentiated somatoform disorder conditions were eliminated and collapsed into the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition somatic symptom disorder diagnosis. With somatic symptom disorder, emphasis was placed on a cognitive-behavioural (psychological) formulation as the basis for diagnosis in individuals reporting distressing bodily symptoms such as pain and/or fatigue; the need for bodily symptoms to be ‘medically unexplained’ was removed, and the overall utility of this diagnostic criteria remains debated. A consequence of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition restructuring is that the diagnosis of somatization disorder that encompassed individuals with functional neurological (sensorimotor) symptoms and prominent other bodily symptoms, including pain, was eliminated. This change negatively impacts clinical and research efforts because many patients with functional neurological disorder experience pain, supporting that the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition would benefit from an integrated diagnosis at this intersection. We seek to revisit this with modifications, particularly since pain (and a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition somatization disorder comorbidity, more specifically) is associated with poor clinical prognosis in functional neurological disorder. As a first step, we systematically reviewed the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition somatization disorder literature to detail epidemiologic, healthcare utilization, demographic, diagnostic, medical and psychiatric comorbidity, psychosocial, neurobiological and treatment data. Thereafter, we propose a preliminary revision to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition allowing for the specifier functional neurological disorder ‘with prominent pain’. To meet this criterion, core functional neurological symptoms (e.g. limb weakness, gait difficulties, seizures, non-dermatomal sensory loss and/or blindness) would have ‘rule-in’ signs and pain (>6 months) impairing social and/or occupational functioning would also be present. Two optional secondary specifiers assist in characterizing individuals with cognitive-behavioural (psychological) features recognized to amplify or perpetuate pain and documenting if there is a pain-related comorbidity. The specifier of ‘with prominent pain’ is etiologically neutral, while secondary specifiers provide additional clarification. We advocate for a similar approach to contextualize fatigue and mixed somatic symptoms in functional neurological disorder. While this preliminary proposal requires prospective data and additional discussion, these revisions offer the potential benefit to readily identify important functional neurological disorder subgroups—resulting in diagnostic, treatment and pathophysiology implications.

Insular Cortical Thickness in Patients With Somatoform Pain Disorder: Are There Associations With Symptom Severity and Childhood Trauma?

BACKGROUND

Studies show significant alterations in insular cortical thickness in patients with somatoform pain disorder (SPD). Additionally, associations between childhood maltreatment and morphometric alterations in insular cortex have been observed. Since patients with SPD often report about adverse childhood experiences, we were interested in the interrelationship of exposure to childhood maltreatment and insular cortical thickness in patients with SPD.

METHODS

Fifteen adult patients with SPD (ICD-10 F 45.40/41, DSM-Code 307.80) and thirteen healthy adult controls underwent T1-weighted MR brain imaging. In the voxel-based morphometry (VBM) analysis we compared whole brain cortical thickness between patients and controls using a Student's two-sampled t-test (p < .05). Then we performed a secondary analysis to detect differences in cortical thickness levels in the insular cortex between both groups. For further analysis of differences in insular cortical thickness we used gender, age, depressive symptoms [Patient Health Questionnaire (PHQ)-9], and whole brain cortical thickness as nuisance covariates. Subsequently we explored associations between insular cortical thickness, symptom severity (PHQ-15) and past experiences of childhood maltreatment (CTQ) in both groups.

RESULTS

Patients showed reduced insular cortical thickness in a subregion of right Brodmann area (BA) 13 (anterior part of the insular cortex), whereas whole brain cortical thickness did not differ between groups. The between-group difference in the identified insular subregion of right BA 13 was not diminished by any of the covariates. This implies that the reduction in cortical thickness in the identified insular subregion might be due to a specific group effect. The effect sizes indicate that the group of patients experienced more childhood maltreatment than the control group. Nonetheless, significant correlations of insular cortical thickness with symptom severity and childhood maltreatment in the total collective could not be demonstrated for the group of patients.

CONCLUSIONS

Our data suggest that alterations in the identified insular subregion of right BA 13 are associated with somatoform pain, independent of gender, age, or coincident depression levels. To identify significant associations of insular cortical thickness and experiences of childhood maltreatment in patients with SPD investigations within larger samples are highly recommended.

Childhood trauma and somatic symptoms among psychiatric outpatients: Investigating the role of shame and guilt

Previous research suggests a link between experiences of childhood maltreatment and adult somatic symptom distress. Contributing mechanisms, however, are not yet well understood. It is possible that shame and guilt may function as mediators in the relationship between childhood trauma and adult somatic distress. The present study was developed to investigate the relationship between childhood maltreatment and adult somatic distress, including the potential mediating role of shame and guilt, among psychiatric outpatients. Using data from a sample of 99 Canadian psychiatric outpatients, mediation models with shame and guilt as parallel mediators were evaluated for relationships between childhood emotional abuse, sexual abuse, emotional neglect, and somatic symptoms. Controlling for current depressive symptoms, a significant indirect effect was found for the relationship between emotional abuse and shame, but not guilt, in contributing to somatic symptoms. A similar result was obtained regarding the mediating role of shame in the relationship between emotional neglect and somatic symptoms. Mediation was non-significant regarding childhood sexual abuse, which was directly related to somatic distress after controlling for depressive symptoms. The findings provide further evidence of the link between childhood trauma and somatic symptom distress, with shame as a mechanism for the effects of emotional abuse and neglect.

Insecure attachment style and cumulative traumatic life events in patients with somatoform pain disorder: A cross-sectional study

OBJECTIVE

Current models assume somatoform pain disorder (SPD) to be the result of a complex interaction between bio- and psychosocial factors, but the etiology is still not well understood. This study aimed to investigate the distribution of attachment style and the frequency of traumatic life events, especially childhood adversities, in patients with SPD compared to healthy controls.

METHODS

We compared 65 patients with SPD (confirmed by Structured Clinical Interview, SCID-I) to 65 age- and gender-matched healthy controls. The following questionnaires were employed: Relationship Scale Questionnaire (RSQ), Essen Trauma Inventory (ETI), Childhood Trauma Questionnaire (CTQ) and Patient Health Questionnaire (PHQ-15). A logistic regression analysis was used to identify the association between SPD and psychological factors.

RESULTS

Insecure attachment was significantly more prevalent (60%) in patients with SPD compared to healthy subjects (14%; p<0.001). Overall, 70.4% of patients with SPD reported three or more traumatic events in their life, compared with healthy subjects who reported predominantly one (40%). Patients with SPD scored significantly higher in all CTQ subscales compared to the healthy controls. The factor most strongly related with SPD was the insecure attachment style (OR=11.20, 95% CI: 1.32-94.86). Other significant predictive factors were depression (OR=3.35, 95% CI: 1.84-6.11) and number of traumatic events (OR=2.04, 95% CI: 1.06-3.92). Insecure attachment, depression symptoms and the number of traumatic events explained 86.2% of the variance.

CONCLUSIONS

The high predictive value of insecure attachment style and cumulative traumatic events emphasize their importance as risk factors of SPD.

Clinical Profile Associated with Adverse Childhood Experiences: The Advent of Nervous System Dysregulation

Background: We report the prevalence of children with multiple medical symptoms in a pediatric neurology clinic, describe their symptom profiles, and explore their association with adverse childhood experiences (ACEs). Methods: We retrospectively reviewed 100 consecutive patients from an outpatient pediatric neurology clinic. Patients were included if they were ≥5 years old and reported ≥4 symptoms that were unexplained for ≥3-months. Symptom profiles across six functional domains were recorded: (1) executive dysfunction, (2) sleep disturbances, (3) autonomic dysregulation, (4) somatization, (5) digestive symptoms, and (6) emotional dysregulation. ACEs were scored for all patients. Results: Seventeen patients reported ≥4 medical symptoms. Somatization, sleep disturbances, and emotional dysregulation occurred in 100% patients, with executive dysfunction (94%), autonomic dysregulation (76%), and digestive problems (71%) in the majority. Forty-two children reported ≥1 ACE, but children with ≥4 symptoms were more likely to report ACEs compared to other children (88% vs. 33%; p < 0.0001) and had a higher median total ACE score (3 vs. 1; p < 0.001). Conclusions: Children with multiple medical symptoms should be screened for potential exposure to ACEs. A clinical profile of symptoms across multiple functional domains suggests putative neurobiological mechanisms involving stress and nervous system dysregulation that require further study.

Childhood abuse in adults in primary care: Empirical findings and clinical implications

In the healthcare setting, adult patients with histories of childhood abuse are of significant concern and are frequently encountered in the primary care setting. However, there is a dearth of studies investigating the relationships between psychopathology, overall health, healthcare utilization, physician ratings of patient difficulty, and childhood abuse. The present study examines these relationships in primary care patients with (N = 45) and without (N = 129) histories of childhood abuse (physical, sexual, and both). Findings revealed that adult patients with histories of childhood abuse generally scored significantly higher on measures of psychopathology, emergency room use, and doctor-patient relationship difficulty, and lower on a measure of mental and physician-rated physical health. In a multiple regression analysis, income and a history of childhood sexual abuse significantly predicted overall mental health. In a second multiple regression analysis, income, depression, somatization, borderline personality disorder, and difficult doctor-patient relationship ratings significantly predicted physician-rated physical health. Overall, these findings suggest that a history of childhood abuse is associated with a host of negative health outcomes. Findings also suggest that negative feelings about a patient may help physicians identify patients with histories of childhood abuse. It is especially important for physicians to routinely include an assessment of childhood abuse during the psychosocial portion of the medical interview or through screening instruments.

Factorial Validity of the Short Form of the Childhood Trauma Questionnaire (CTQ—SF) in German Psychiatric Patients, Inmates, and University Students

For the purpose of retrospective assessment and characterization of childhood trauma in adults, the factorial validity of the short form of the Childhood Trauma Questionnaire (CTQ–SF) in Germany was evaluated by conducting confirmatory factor analyses for three samples including 1,524 adult psychiatric patients, 224 inmates, and 295 university students. In addition, sex-specific confirmatory factor analyses were performed within each sample. Because several authors have suggested a different factor structure than that originally proposed in the manual, two competing models focusing on the Physical neglect subscale were examined. In psychiatric patients and inmates, the fit indices were reasonable to good. Among the students, factor loadings were markedly lower, and fit indices were poor. Sex-specific analyses did not indicate sex differences. Comparing the original and the alternative models revealed better fit indices of the original factor structure. The present findings indicate that the German version of the CTQ–SF has factorial validity in psychiatric patients and inmates, but not in students.

Attachment in romantic relationships and somatization

Adult attachment representations have been considered to play a role in the development and treatment of somatizing behavior. In this study, the associations between the two attachment dimensions avoidance and anxiety and dimensions of psychopathology (somatization, depression, and general anxiety) were explored. The sample consists of 202 outpatients diagnosed with a somatoform disorder. Data were collected via self-report measures. A path analysis shows that the two attachment dimensions are not directly associated with somatization. There are, however, significant indirect associations between attachment and somatization mediated by depression and general anxiety, which are more pronounced for attachment anxiety than for attachment avoidance. The findings reveal that a low level of attachment security in romantic relationships, especially an anxious stance toward the partner, comes along with poor mental health, which in turn is related to a preoccupation with somatic complaints. Implications for the treatment of somatizing patients are discussed.

Trauma-related psychiatric comorbidity of somatization disorder among women in eastern Turkey

OBJECTIVE

This study sought to determine the trauma-related psychiatric comorbidity of somatization disorder among women who applied to an outpatient psychiatric unit of a general hospital in eastern Turkey.

METHODS

Forty women with somatization disorder and 40 non-clinical controls recruited from the same geographic region participated in the study. Somatization disorder and posttraumatic stress disorder (PTSD) sections of the Structured Clinical Interview for DSM-IV (including its criterion A traumatic events checklist), Dissociative Disorders Interview Schedule, Dissociative Experiences Scale (Taxon), Hamilton Depression Rating Scale, and Childhood Abuse and Neglect Questionnaire were administered to all participants.

RESULTS

A significant proportion of the women with somatization disorder had the concurrent diagnoses of major depression, PTSD, dissociative disorder, and borderline personality disorder. Women with somatization disorder reported traumatic experiences of childhood and/or adulthood more frequently than the comparison group. A significant proportion of these patients reported possession and/or paranormal experiences. Binary logistic regression analysis demonstrated that current major depression, being married, total number of traumatic events in adulthood, and reports of possession and/or paranormal experiences were independent risk factors for somatization disorder diagnosis.

CONCLUSIONS

Among women with endemically high exposition to traumatic stress, multiple somatic complaints were in a significant relationship with major depressive disorder and lifelong cumulative traumatization. While accompanying experiences of possession and paranormal phenomena may lead to seeking help by paramedical healers, the challenge of differential diagnosis may also limit effective service to this group of somatizing women with traumatic antecedents and related psychiatric comorbidities.

Characteristics of medically hospitalized pediatric patients with somatoform diagnoses

OBJECTIVES

To describe demographic, diagnostic, and psychosocial characteristics of medically admitted patients diagnosed with somatoform disorders.

METHODS

Retrospective chart reviews were performed for pediatric patients (ages 3-18 years) seen by the Psychiatry Consultation Service in 2010 and 2011 on inpatient medical/surgical units and diagnosed with somatoform disorders. Data included demographic information; patient medical history, physical symptom characteristics, and service utilization; psychiatric diagnoses, history, and comorbidities, patient temperament, and coping style; family characteristics; and academic and social characteristics.

RESULTS

Mean age for the 161 identified patients was 14.4 years. The majority of patients were female (75%) and white (73%). Chief physical symptoms were pain (58%) and neurologic symptoms (40%); 73% of patients had medical diagnoses, and 66% had a history of prior psychiatric treatment. The most common somatoform diagnoses, using the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision, were pain (50%) and conversion disorders (28%). Psychiatric comorbidities were predominantly mood and anxiety disorders (42% and 29%, respectively). Mean hospitalization length was 4.9 days, with 14% of patients readmitted with psychiatric reinvolvement during the study period. Patients had sensitive temperaments (80%) and internalizing coping styles (76%) and were described as "good children" (72%). School absences (55%), academic pressures (51%), and learning difficulties (36%) were reported.

CONCLUSIONS

Clarifying the prevalence and nature of such characteristics can help pediatric providers improve patient care and minimize unnecessary medical interventions with early detection of risk for somatoform processes, provision of psychoeducation for patients and families, and early referral to mental health clinicians.

Psychometric functioning, socio-demographic variability of childhood maltreatment in the general population and its effects of depression

Maltreatment of children is a major public-health and social-welfare problem but socio-demographic variability has received little attention. This work addresses such variability in a general population cohort and associations with depression. Analyses were based on the cross-sectional SHIP-LEGEND examination among 2265 adults (29-89 years). Childhood maltreatment was multi-dimensionally assessed with the German 28-item Childhood Trauma Questionnaire (CTQ): emotional neglect; emotional abuse; physical neglect; physical abuse; sexual abuse. Non-linear associations between CTQ responses and age were assessed with fractional polynomials and cubic splines. Scale properties were analysed with confirmatory factor analyses and item response models. Associations between childhood maltreatment domains and depression [Beck Depression Inventory-II (BDI-II)] were assessed. The majority (58.9%) reported events indicative of at least mild levels of childhood maltreatment. CTQ subscales showed characteristically different non-linear associations to age across the five studied domains, indicating methodological issues like recall bias and the influence of seminal events. Psychometric scale properties were acceptable to good for all subscales except for physical neglect. Associations to depression measures varied systematically across socio-demographic strata. We conclude that socio-demographic variability is a major issue when studying self-reported childhood maltreatment in a community sample. This needs to be taken into account for the study of associations to psychiatric key outcomes.

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

OBJECTIVE

Previous studies demonstrated that a history of childhood trauma is linked to mental disorders in adulthood, particularly to depression. Adverse childhood experiences are also considered to contribute to the risk of hypochondriasis, but the results of previous studies have not been conclusive with respect to the strength and specificity of this association. Therefore, we compared the association of adverse childhood experiences with both hypochondriasis and depression.

METHODS

Fifty-eight patients with hypochondriasis, 52 patients with depression, and 52 healthy control participants completed the Childhood Trauma Questionnaire (CTQ) which assesses 5 varieties of abuse and neglect. A clinical interview (SCID-I) was used to establish DSM-IV diagnoses. Associations between childhood maltreatment, hypochondriasis and depression were estimated by means of analyses of variance and multiple linear regression analyses.

RESULTS

In comparison to hypochondriacal and healthy participants, patients with a current depressive disorder reported more emotional abuse as well as more emotional and physical neglect during childhood. Patients with hypochondriasis reported more emotional neglect than healthy individuals. However, when predicting the CTQ trauma types by diagnostic category adjusting for sex and comorbid DSM-IV diagnoses, emotional abuse, emotional neglect, physical abuse, physical neglect, as well as the CTQ total score were significantly associated with depression, but none of the CTQ scores was significantly related to hypochondriasis.

CONCLUSIONS

The findings suggest a robust association of childhood maltreatment with depression but not with hypochondriasis. This result does not support etiological models of hypochondriasis which rely on childhood maltreatment as a risk factor for the development of this disorder.

Associations between lifetime traumatic events and subsequent chronic physical conditions: a cross-national, cross-sectional study

Background

Associations between lifetime traumatic event (LTE) exposures and subsequent physical ill-health are well established but it has remained unclear whether these are explained by PTSD or other mental disorders. This study examined this question and investigated whether associations varied by type and number of LTEs, across physical condition outcomes, or across countries.

Methods

Cross-sectional, face-to-face household surveys of adults (18+) were conducted in 14 countries (n = 38, 051). The Composite International Diagnostic Interview assessed lifetime LTEs and DSM-IV mental disorders. Chronic physical conditions were ascertained by self-report of physician's diagnosis and year of diagnosis or onset. Survival analyses estimated associations between the number and type of LTEs with the subsequent onset of 11 physical conditions, with and without adjustment for mental disorders.

Findings

A dose-response association was found between increasing number of LTEs and odds of any physical condition onset (OR 1.5 [95% CI: 1.4–1.5] for 1 LTE; 2.1 [2.0–2.3] for 5+ LTEs), independent of all mental disorders. Associations did not vary greatly by type of LTE (except for combat and other war experience), nor across countries. A history of 1 LTE was associated with 7/11 of the physical conditions (ORs 1.3 [1.2–1.5] to 1.7 [1.4–2.0]) and a history of 5+ LTEs was associated with 9/11 physical conditions (ORs 1.8 [1.3–2.4] to 3.6 [2.0–6.5]), the exceptions being cancer and stroke.

Conclusions

Traumatic events are associated with adverse downstream effects on physical health, independent of PTSD and other mental disorders. Although the associations are modest they have public health implications due to the high prevalence of traumatic events and the range of common physical conditions affected. The effects of traumatic stress are a concern for all medical professionals and researchers, not just mental health specialists.

Changes in brain activity of somatoform disorder patients during emotional empathy after multimodal psychodynamic psychotherapy

Somatoform disorder patients show a variety of emotional disturbances including impaired emotion recognition and increased empathic distress. In a previous paper, our group showed that several brain regions involved in emotional processing, such as the parahippocampal gyrus and other regions, were less activated in pre-treatment somatoform disorder patients (compared to healthy controls) during an empathy task. Since the parahippocampal gyrus is involved in emotional memory, its decreased activation might reflect the repression of emotional memories (which—according to psychoanalytical concepts—plays an important role in somatoform disorder). Psychodynamic psychotherapy aims at increasing the understanding of emotional conflicts as well as uncovering repressed emotions. We were interested, whether brain activity in the parahippocampal gyrus normalized after (inpatient) multimodal psychodynamic psychotherapy. Using fMRI, subjects were scanned while they shared the emotional states of presented facial stimuli expressing anger, disgust, joy, and a neutral expression; distorted stimuli with unrecognizable content served as control condition. 15 somatoform disorder patients were scanned twice, pre and post multimodal psychodynamic psychotherapy; in addition, 15 age-matched healthy control subjects were investigated. Effects of psychotherapy on hemodynamic responses were analyzed implementing two approaches: (1) an a priori region of interest approach and (2) a voxelwise whole brain analysis. Both analyses revealed increased hemodynamic responses in the left and right parahippocampal gyrus (and other regions) after multimodal psychotherapy in the contrast “empathy with anger”—“control.” Our results are in line with psychoanalytical concepts about somatoform disorder. They suggest the parahippocampal gyrus is crucially involved in the neurobiological mechanisms which underly the emotional deficits of somatoform disorder patients.

"When the pain won't wane it's mainly in the brain"

Chronic pain syndromes either have no underlying organic explanation, or include patients whose chronic pain complaints (without focal deficits or significant radiographic findings) were not alleviated by surgery (in 80% of cases). Patients with chronic pain typically "turn off" members of the medical community; they are often "written off" as malingerers or psychiatric cases. The Minnesota Multiphasic Personality Inventory often shows elevations on the hysteria and hypochondriasis scales; together these constitute somatization defined as patients converting emotional distress into bodily complaints. Depression, anxiety, and borderline personality disorders are also often encountered. Secondary gain also plays a critical role in patients with chronic pain syndromes (e.g., includes avoiding onerous tasks/work, or rewards opioid-seeking behaviors). Tertiary gain pertains to the physicians' financial rewards for administering ineffective and repeated treatment of these patients, while validating for the patient that there is truly something organically wrong with them. Self-mutilation (part of Munchausen Syndrome/Fictitious Disorders) also brings these chronic pain patients to the attention of the medical community. They are also often involved in the legal system (e.g., workmen's compensation or tort action) that in the United States, unfortunately financially rewards "pain and suffering." The main purpose of this commentary is to reeducate spinal surgeons about the pitfalls of operating on patients with chronic pain syndromes in the absence of significant neurological deficits or radiographic findings, as such "last ditch surgery" invariably fails.

Effects of childhood trauma on somatization in major depressive disorder: The role of alexithymia

BACKGROUND

Childhood trauma (CT) is often associated with later psychopathology, including depression, somatization, and alexithymia. The aim of the present study was to investigate the relationships of CT with somatization and alexithymia. Moreover, the effect of specific subtypes of trauma on alexithymia and somatization was also investigated.

METHODS

The present study was conducted on 100 outpatients with major depressive disorder (MDD) and 50 age and gender matched healthy controls (HC). Data were collected on each of the participants, including the Childhood Trauma Questionnaire (CTQ-28), the Hamilton Anxiety Rating Scale (HARS), the Hamilton Depression Rating Scale (HDRS), a 20-item Toronto Alexithymia Scale (TAS), and a somatization subscale of the Symptom Check List-Revised Form (SCL-90 R). Patient groups were divided into two categories according to the TAS-20 cut-off score. Reliability and validity were assessed, and factor analyses were conducted on the CTQ-28. Next, the relationships among CT subtypes, alexithymia, and somatization were investigated using Pearson's and partial correlation analysis. Additionally, the types of CT that predict alexithymia and somatization were also investigated.

RESULTS

Significantly higher scores on the clinical variables were noted in the patient group compared with the control group, except for physical neglect on the CTQ. The partial correlation of the CT types with somatization and alexithymia showed that the HARS, HDRS, somatization subscale of the SCL-90 R (for alexithymia), and the TAS-total (for somatization) were covariates. None of the CT types was correlated with somatization, whereas physical abuse and emotional neglect were correlated with alexithymia. Moreover, emotional abuse and emotional neglect predicted scores on the TAS and on the somatization subscale of the SCL-90 R. Conclusions CT is associated with alexithymia and ongoing somatic complaints. Alexithymia contributes to the emergence of somatic symptoms in MDD, particularly following CT. Somatization also contributes to alexithymia. Interestingly, the present study found that the relationship of emotional neglect and physical abuse with alexithymia was independent from somatization. Taken together, these results indicate that emotional abuse and neglect predict the later emergence of alexithymia and somatization.

Symptoms of depression, anxiety, and somatization in female victims and perpetrators of intimate partner violence in Maputo City, Mozambique

BACKGROUND

Little knowledge exists in Mozambique and sub-Saharan Africa about the mental health (symptoms of depression, anxiety, and somatization) of women victims and perpetrators of intimate partner violence (IPV) by type of abuse (psychological aggression, physical assault without/with injury, and sexual coercion). This study scrutinizes factors associated with mental health among women victims and perpetrators of IPV over the 12 months prior to the study.

METHODS AND MATERIALS

Mental health data were analyzed with bivariate and multiple regression methods for 1442 women aged 15-49 years who contacted Forensic Services at Maputo Central Hospital (Maputo City, Mozambique) for IPV victimization between April 1, 2007 and March 31, 2008.

RESULTS

In bivariate analyses, victims and perpetrators of IPVs scored higher on symptoms of mental health than their unaffected counterparts. Multiple regressions revealed that controlling behaviors, mental health comorbidity, social support, smoking, childhood abuse, sleep difficulties, age, and lack of education were more important in explaining symptoms of mental health than demographics/socioeconomics or life-style factors. Victimization and perpetration across all types of IPV were not associated with symptoms of mental health.

CONCLUSION

In our sample, victimization and perpetration were not important factors in explaining mental ill health, contrary to previous findings. More research into the relationship between women's IPV victimization and perpetration and mental health is warranted as well as the influence of controlling behaviors on mental health.

Diagnosis and treatment of somatoform disorders

Many patients with somatoform disorders present to the neurology clinic, often after extensive evaluation that has left the patient and multiple other physicians frustrated. Knowledge of the typical characteristics of particular disorders enables the clinician to arrive at a positive diagnosis and facilitate referral to appropriate services. Using a series of representative cases, we review the DSM-IV-TR somatoform disorders most likely to present to the practicing neurologist, highlighting the epidemiologic features, typical presentations, and possible therapeutic approaches to each condition.

Familial risk factors for the development of somatoform symptoms and disorders in children and adolescents: a systematic review

The aim of this study was to examine whether familial risk factors for the development of somatoform symptoms and somatoform disorders in children and adolescents can be deduced from studies which investigated the intergenerational transmission of functional abdominal pain and somatoform disorders. A systematic review of articles published in English and German since 1990 was performed. Twenty-three relevant studies were found. The following putative familial risk factors for the development of somatoform symptoms and somatoform disorders were identified: somatization of parents, organic disease of a significant other, psychopathology of close family members, dysfunctional family climate, traumatic experiences in childhood and insecure attachment. Most of the putative familial risk factors are associated with many other psychiatric child disorders and are therefore mostly nonspecific. Further longitudinal studies, in which comorbidity and other putative risk factors are taken into account, are needed to identify specific familial risk factors for the development of somatoform symptoms and somatoform disorders.

From traumatic attachment to somatization disorder

OBJECTIVE

This paper emphasizes attachment trauma as an important etiological factor in somatization disorder and psychoanalytic psychotherapy as an effective treatment.

METHOD

Weekly psychotherapy with an 18 year old with somatization disorder, using the Conversational Model, is described.

CONCLUSION

Early cumulative trauma has far-reaching health consequences. Brief psychotherapy produces symptom relief, and long-term analytic therapy is necessary for sustained improvement.

Differential effects of childhood abuse and neglect: mediation by posttraumatic distress in neurotic disorder and negative symptoms in schizophrenia?

Dissociation, though understood as a response to trauma, lacks a proven etiology. The assumption of a dose-response relationship between trauma, dissociation and Schneiderian symptoms led to the proposal of a dissociative subtype of schizophrenia characterized by severe child maltreatment, dissociation and psychosis. Child maltreatment and dissociation are common features of neurotic disorders as well, and the link between trauma, dissociation, and hallucinations is not specific for schizophrenia. This study compares childhood abuse and neglect, posttraumatic distress and adult dissociation in patients with psychotic vs. non-psychotic disorder. Thirty-five participants with non-psychotic disorder and twenty-five with schizophrenia were analyzed using the Scale for the Assessment of Positive Symptoms (SAPS), the Scale for the Assessment of Negative Symptoms (SANS), the Montgomery-Åsberg Depression Rating Scale (MADRS), the Posttraumatic Stress Diagnostic Scale PDS (PDS), the Childhood Trauma Questionnaire (CTO) and the Arbeitsgemeinschaft Methodik und Dokumentation in der Psychiatrie (AMDP)-module on dissociation. Trauma and clinical syndromes were compared by means of T-testing and logistic regression between 1) the diagnoses and 2) groups with and without post-traumatic stress disorder (PTSD), marked dissociation and psychotic symptoms. While non-psychotic disorder was related to abuse, schizophrenia showed an association with neglect. Childhood trauma predicted posttraumatic symptomatology and negative symptoms. Childhood abuse and neglect may effectuate different outcomes in neurotic and psychotic disorder. The underlying mechanisms, including dissociation, dovetail with cognitive, emotional and behavioural changes involved in depression, posttraumatic distress and chronic schizophrenia symptoms rather than being directly linked to trauma.

Depression: a repair response to stress-induced neuronal microdamage that can grade into a chronic neuroinflammatory condition?

Depression is a major contributor to the global burden of disease and disability, yet it is poorly understood. Here we review data supporting a novel theoretical model for the biology of depression. In this model, a stressful life event leads to microdamage in the brain. This damage triggers an injury repair response consisting of a neuroinflammatory phase to clear cellular debris and a spontaneous tissue regeneration phase involving neurotrophins and neurogenesis. During healing, released inflammatory mediators trigger sickness behavior and psychological pain via mechanisms similar to those that produce physical pain during wound healing. The depression remits if the neuronal injury repair process resolves successfully. Importantly, however, the acute psychological pain and neuroinflammation often transition to chronicity and develop into pathological depressive states. This hypothesis for depression explains substantially more data than alternative models, including why emerging data show that analgesic, anti-inflammatory, pro-neurogenic and pro-neurotrophic treatments have antidepressant effects. Thus, an acute depressive episode can be conceptualized as a normally self-limiting but highly error-prone process of recuperation from stress-triggered neuronal microdamage.

Sexual abuse and lifetime diagnosis of psychiatric disorders: systematic review and meta-analysis

OBJECTIVE

To systematically assess the evidence for an association between sexual abuse and a lifetime diagnosis of psychiatric disorders.

PATIENTS AND METHODS

We performed a comprehensive search (from January 1980-December 2008, all age groups, any language, any population) of 9 databases: MEDLINE, EMBASE, CINAHL, Current Contents, PsycINFO, ACP Journal Club, CCTR, CDSR, and DARE. Controlled vocabulary supplemented with keywords was used to define the concept areas of sexual abuse and psychiatric disorders and was limited to epidemiological studies. Six independent reviewers extracted descriptive, quality, and outcome data from eligible longitudinal studies. Odds ratios (ORs) and 95% confidence intervals (CIs) were pooled across studies by using the random-effects model. The I(2) statistic was used to assess heterogeneity.

RESULTS

The search yielded 37 eligible studies, 17 case-control and 20 cohort, with 3,162,318 participants. There was a statistically significant association between sexual abuse and a lifetime diagnosis of anxiety disorder (OR, 3.09; 95% CI, 2.43-3.94), depression (OR, 2.66; 95% CI, 2.14-3.30), eating disorders (OR, 2.72; 95% CI, 2.04-3.63), posttraumatic stress disorder (OR, 2.34; 95% CI, 1.59-3.43), sleep disorders (OR, 16.17; 95% CI, 2.06-126.76), and suicide attempts (OR, 4.14; 95% CI, 2.98-5.76). Associations persisted regardless of the victim's sex or the age at which abuse occurred. There was no statistically significant association between sexual abuse and a diagnosis of schizophrenia or somatoform disorders. No longitudinal studies that assessed bipolar disorder or obsessive-compulsive disorder were found. Associations between sexual abuse and depression, eating disorders, and posttraumatic stress disorder were strengthened by a history of rape.

CONCLUSION

A history of sexual abuse is associated with an increased risk of a lifetime diagnosis of multiple psychiatric disorders.

The relationship between childhood trauma and medically self-sabotaging behaviors among psychiatric inpatients

OBJECTIVE

This study was designed to explore the relationship between five forms of childhood trauma and medically self-sabotaging behaviors (i.e., the intentional induction, exaggeration, and/or exacerbation of medical symptoms).

METHOD

Using a cross-sectional sample of convenience, 120 psychiatric inpatients were surveyed about childhood sexual, physical, and emotional abuses, the witnessing of violence, and physical neglect, as well as 19 medically self-sabotaging behaviors (i.e., intentional behaviors that represent attempts to sabotage medical care).

RESULTS

As expected, in this sample there were high prevalence rates of trauma (62.5% emotional abuse, 58.3% witnessing of violence, 46.7% physical abuse, 37.5% sexual abuse, 28.3% physical neglect). Simple correlations demonstrated statistically significant relationships between sexual abuse and physical neglect and medically self-sabotaging behaviors. Using multiple regression analysis, only physical neglect remained a unique predictor of medically self-sabotaging behaviors.

CONCLUSIONS

These findings indicate that among psychiatric inpatients there appears to be a relationship between physical neglect in childhood and the generation of medically self-sabotaging behaviors in adulthood. Perhaps physical neglect in childhood contributes to the generation of somatic behaviors in adulthood for the purpose of eliciting caring responses from others.

Complex post-traumatic stress disorder in patients with somatization disorder

OBJECTIVE

Given the association between severe childhood trauma, adult somatization and complex post-traumatic stress disorder (cPTSD), the purpose of the present paper was to assess this syndrome and its clinical correlates in patients with somatization disorder (SD).

METHODS

A total of 28 patients (82% women, mean age = 41.7+/-10.1 years) meeting DSM-IV criteria for SD as confirmed by the Structured Clinical Interview for DSM-IV, Axis I were compared to 28 age- and gender-matched patients with major depression, but without a lifetime diagnosis of SD. They completed the Structured Interview for Disorders of Extreme Stress, the Brief Symptom Inventory, the Inventory of Interpersonal Problems-Circumplex Scales, and the SF-36 Health Survey.

RESULTS

Compared to the control group, SD patients had higher risks for current and lifetime diagnoses of cPTSD (odds ratio (OR) = 15.0, 95% confidence interval (CI) = 1.76-127.54; and OR = 8.33, 95%CI = 2.04-34.07, respectively). SD subjects with cPTSD had more psychological distress, more interpersonal problems and worse psychosocial functioning than those without the syndrome.

CONCLUSION

The concept of complex PTSD may hold clinical utility when applied to SD patients because it identifies a distinct subgroup characterized by severe psychosocial impairment. The diagnostic and therapeutic implications of the present findings are discussed.

Cognitive-affective neuroscience of somatization disorder and functional somatic syndromes: reconceptualizing the triad of depression-anxiety-somatic symptoms

Somatization disorder is a somatoform disorder that overlaps with a number of functional somatic syndromes and has high comorbidity with major depression and anxiety disorders. Proposals have been made for revising the category of somatoform disorders, for simplifying the criteria for somatization disorder, and for emphasizing the unitary nature of the functional somatic syndromes in future classifications. A review of the cognitive-affective neuroscience of somatization disorder and related conditions suggests that overlapping psychobiological mechanisms mediate depression, anxiety, and somatization symptoms. Particular genes and environments may contribute to determining whether symptoms are predominantly depressive, anxious, or somatic, and there are perhaps also overlaps and distinctions in the distal evolutionary mechanisms that produce these symptoms.
