Psychopathological characteristics of recovered bulimics who have a history of physical or sexual abuse

Comparing the clinical presentation of eating disorder patients with and without trauma history and/or comorbid PTSD

This study examined whether clinical characteristics among patients presenting to residential eating disorder (ED) treatment differed according to patients' trauma history and current PTSD diagnostic status. Participants (699 girls and women) completed surveys at treatment onset. One-way analysis of covariance (ANCOVA) tests assessed cross-sectional differences between three groups of patients: those reporting no trauma history (No Trauma, n = 185), those with trauma history but without PTSD (Trauma, n = 263), and those with current PTSD (PTSD, n = 251). Relative to the No Trauma group, the combined Trauma and PTSD groups reported greater ED symptoms, anxiety and depressive symptoms, experiential avoidance, anxiety sensitivity, and lower mindfulness. The PTSD group reported greater ED, anxiety, and depressive symptoms, greater anxiety sensitivity, and lower mindfulness, relative to the Trauma group. In sum, ED patients with any history of trauma experienced more symptoms and other psychopathology relative to patients who did not report trauma history. Among patients reporting trauma, those with current PTSD experienced even greater symptom severity. Interventions focused on improving emotional functioning could be especially beneficial for ED patients with trauma histories.

Childhood maltreatment and eating disorder pathology: a systematic review and dose-response meta-analysis

BACKGROUND

Meta-analyses have established a high prevalence of childhood maltreatment (CM) in patients with eating disorders (EDs) relative to the general population. Whether the prevalence of CM in EDs is also high relative to that in other mental disorders has not yet been established through meta-analyses nor to what extent CM affects defining features of EDs, such as number of binge/purge episodes or age at onset. Our aim is to provide meta-analyses on the associations between exposure to CM (i.e. emotional, physical and sexual abuse) on the occurrence of all types of EDs and its defining features.

METHOD

Systematic review and meta-analyses. Databases were searched until 4 June 2016.

RESULTS

CM prevalence was high in each type of ED (total N = 13 059, prevalence rates 21-59%) relative to healthy (N = 15 092, prevalence rates 1-35%) and psychiatric (N = 7736, prevalence rates 5-46%) control groups. ED patients reporting CM were more likely to be diagnosed with a co-morbid psychiatric disorder [odds ratios (ORs) range 1.41-2.46, p < 0.05] and to be suicidal (OR 2.07, p < 0.001) relative to ED subjects who were not exposed to CM. ED subjects exposed to CM also reported an earlier age at ED onset [effect size (Hedges' g) = -0.32, p < 0.05], to suffer a more severe form of the illness (g = 0.29, p < 0.05), and to binge-purge (g = 0.31, p < 0.001) more often compared to ED patients who did not report any CM.

CONCLUSION

CM, regardless of type, is associated with the presence of all types of ED and with severity parameters that characterize these illnesses in a dose dependent manner.

“It Wasn’t About Being Slim”

This article explores how women understand and experience the relationship between physical, sexual, and emotional abuse and the emergence of an eating disorder in their lives. The past three decades have seen increased attention to the links between abuse and eating disorders; however, the social contexts of abuse, the specific emotions involved, and how these might link to an eating disorder have not been explored. Through an in-depth interview study with 14 women, narrative-discursive analysis reveals how socially situated, abuse-related emotions, such as shame and self-contempt, can play out in an eating disorder and are located within social power relations framed primarily by gender but also by race and class.

Threshold and subthreshold post-traumatic stress disorder in bulimic patients: prevalences and clinical correlates

OBJECTIVE

Post-traumatic stress disorder (PTSD) is believed to impact the clinical presentation and treatment response in bulimia nervosa (BN), but available data do not clarify the clinical implications of subthreshold forms of PTSD, believed to affect a sizable proportion of bulimic women.

METHOD

In 78 women with BN and 61 women who ate normally, we assessed lifetime rates of threshold and subthreshold PTSD, and examined clinical correlates.

RESULTS

Among bulimic women, rate of threshold PTSD was 17.9% and rate of a formally-defined, subthreshold PTSD syndrome was 41.0%. Bulimic women with subthreshold PTSD did not differ from women with threshold PTSD on any clinical indices (except generalized anxiety disorder) and both groups with a PTSD-spectrum syndrome displayed worse psychiatric symptoms than did bulimic women without PTSD symptoms.

DISCUSSION

Threshold and subthreshold variants of PTSD occur substantially more frequently among bulimic women than they do among normal-eater women. Intriguingly, bulimic women with subthreshold PTSD appear to be at similar risk for psychiatric morbidity as are those with threshold PTSD. The preceding suggests that formal, categorical concepts of PTSD may not fully reflect important trauma correlates seen in women with BN.

Trait-defined eating-disorder subtypes and history of childhood abuse

OBJECTIVE

In participants with eating disorders (EDs), prior physical or sexual abuse has been associated with increased likelihood of impulsivity and affective instability. However, previous studies among participants with eating disorders have not systematically explored relationships between empirically derived, personality-trait-based classes, on the one hand, and likelihood of exposure to either childhood sexual or physical abuse, on the other.

METHOD

We assessed multiple psychopathological traits, eating symptoms, and history of abuse in 185 women with an ED and 93 with no ED.

RESULTS

A latent class analysis, conducted using psychopathological-trait measures, yielded latent classes of participants with eating disorders fitting the descriptors "dissocial/impulsive," "inhibited/compulsive," and "low psychopathology." ED was generally associated with increased risk of childhood sexual abuse, but the dissocial/impulsive characteristic corresponded with a unique likelihood of physical abuse and especially high rates of sexual abuse.

DISCUSSION

Observed associations between different forms of childhood abuse and trait-defined ED variants help inform models on the development of eating disorders and of psychopathological traits that often accompany them.

Eating disorders, trauma, and comorbidity: focus on PTSD

This paper reviews the relationships among eating disorders (EDs), trauma, and comorbid psychiatric disorders, with a particular focus on posttraumatic stress disorder (PTSD). There have been a number of significant conclusions in the literature, applicable to clinical practice, which are essential to the understanding of the relationships between EDs and trauma. These are summarized as follows: a) childhood sexual abuse (CSA) is a nonspecific risk factor for EDs; b) the spectrum of trauma linked to EDs has been extended from CSA to include a variety of other forms of abuse and neglect; c) trauma is more common in bulimic EDs compared to nonbulimic EDs; d) findings linking EDs with trauma have been extended to children and adolescents with EDs; e) findings linking EDs with trauma have been extended to boys and men with EDs; f) multiple episodes or forms of trauma are associated with EDs; g) trauma is not necessarily associated with greater ED severity; h) trauma is associated with greater comorbidity (including and often mediated by PTSD) in ED subjects; i) partial or subthreshold PTSD may also be a risk factor for BN and bulimic symptoms; and j) the trauma and PTSD or its symptoms must be expressly and satisfactorily addressed in order to facilitate full recovery from the ED and all associated comorbidity.

Phenotypes, endophenotypes, and genotypes in bulimia spectrum eating disorders

OBJECTIVES

To review the main phenomenological variants observed among bulimia spectrum syndromes and the factors believed to act etiologically for them and also to generate an etiologic model that accommodates known heterogeneities within the population suffering bulimic syndromes.

METHOD

Defining bulimic syndromes broadly, we address threshold and subthreshold forms of bulimia nervosa (BN) and also the provisional or newly proposed diagnoses of binge eating disorder (BED) and purging disorder (PD). We review evidence bearing on the validity of these diagnostic entities and on the place of sociocultural, family-developmental, neurobiological, and genetic factors in a multidimensional etiologic model for these classifications.

RESULTS

Available data validate certain bulimic phenotypes and subphenotypes that are characterized by such traits as impulsivity or affective instability. Findings associate subphenotypic, or trait-based, variations with putative endophenotypes, such as reduced serotonin transporter activity, and with candidate genotypes affecting the serotonin system; the data also indicate intriguing correspondences between gene environment interactions and subphenotypic variations along such dimensions as novelty seeking.

CONCLUSIONS

Bulimic syndromes sometimes reflect a primary disruption of controls over mood, impulses, and appetite in individuals showing marked psychopathology; at other times, they reflect a more circumscribed erosion of appetitive controls in relatively intact individuals, following prolonged dieting. We argue that dimensional perspectives involving careful attention to comorbid personality traits and symptoms are needed to accommodate existing heterogeneities within the population suffering from bulimia and to characterize the etiologic roles of familial-developmental, neurobiological, and genetic variables (and of interactions among these variables) in bulimic syndromes.

Women's experiences of bulimia nervosa

AIM

This paper reports a study to interpret and understand bulimia nervosa as women experience it.

BACKGROUND

Research into bulimia nervosa has focused on prevalence rates, health complications, comorbidity, neurochemical dysregulation, and cultural influences. Despite a multitude of investigations, little published research appraised bulimic women's personal experiences and understanding of this disorder. Such an understanding would assist health care professionals in providing sensitive, empathetic care.

METHOD

The principles of Heideggerian phenomenology guided the study. Participants were 13 actively bulimic women, aged 18-36 years, with lengths of illness from 1 to 23 years. Data were obtained through interviews, personal diaries, and demographic questionnaires.

FINDINGS

Participants' narratives revealed four themes that characterized the experience of living with bulimia: isolating self, living in fear, being at war with the mind, and pacifying the brain. The practices bulimic women engage in are carried out in secret, and hence participants experienced isolation. Binge eating and self-induced vomiting are considered abnormal behaviours; therefore, participants believed that they were subjected to negative public perceptions, which led to the experience of living in fear. The women feared being judged if others knew about the disorder. Several feared living without bulimia because it had become a significant part of their identity. In addition, these women were terrified of gaining weight or becoming fat. They experienced an internal struggle with the mind. In order to pacify the inner voice, many fed the compulsion to eat, and this resulted in guilt. The women subsequently balanced the experience by getting rid of fullness and erasing guilt, which was primarily achieved through self-induced vomiting.

CONCLUSIONS

Understanding the experience of bulimia for women who suffer from this disorder is important. Bulimia often presents as a chronic and potentially lifelong health issue. Awareness of bulimic women's perspectives could promote a comprehensive appreciation of bulimia, its aetiology, and directions for treatment alternatives.

Treatment implications of Axis-II comorbidity in eating disorders

In this article, we review the clinical research on the implications of comorbid personality disorders (PDs), pathological personality traits, and the expression and response to treatment of those with eating disorders (EDs) (i.e., anorexia and bulimia nervosa, and binge eating disorder). Obsessive-compulsive PDs and related traits, such as perfectionism and rigidity, appear to be clear-cut risk and maintenance factors for anorexia nervosa. In bulimia nervosa, trait impulsivity seems to be related to early termination from therapy and, according to at least some indices, poorer responses to treatment. Dramatic-Erratic PD features, generally more characteristic of binge-purge ED variants, clearly predict a protracted course for general psychiatric symptoms, but may have less prognostic value for eating symptoms. Recent guidelines from two influential bodies--the American Psychiatric Association (APA, 2000) and the United Kingdom's National Institute for Clinical Excellence (NICE, 2004)--both include the concept that "trait-oriented" interventions, targeting personality-linked components like perfectionism, affective instability, impulsivity, and interpersonal disturbances, may optimize treatment effects. In general, the literature supports the recommendation that clinicians should apply well-validated, symptom-focused therapies for the EDs; in addition, clinicians may wish to incorporate trait-focused interventions in patients in whom personality pathology contributes to suboptimal response.

A review of the history of traumatic stress studies in Japan: from traumatic neurosis to PTSD

Based on available literature, this review article investigates traumatic stress studies in Japan from the late 19th century to the present for English speaking audiences. First, traumatic neuroses of war victims, A-bomb survivors, and victims of work-related accidents are discussed. Second, traumatic stress studies of victims of other manmade disasters, such as the sarin gas attacks in Tokyo, domestic violence, and burn injuries. Third, psychological outcomes of natural disaster studies are discussed in relation to social support and help-seeking tendencies of Japan disaster victims.

Bulimia nervosa following psychological and multiple child abuse: support for the self-medication hypothesis in a population-based cohort study

OBJECTIVE

To unravel the complex role of child abuse as a risk factor for bulima nervosa (BN), from the perspective of the self-medication hypothesis which asserts that in abused BN cases binge eating is primarily a way of coping with the anxiety or mood disorders that stem from the abuse.

METHOD

In a population-based study (N = 1,987) DSM-III-R diagnoses were assessed with the CIDI. Differences in exposure rates to child abuse between BN cases versus healthy, psychiatric, substance use, and dual diagnosis controls were employed to test the self-medication hypothesis.

RESULTS

A history of psychological or multiple abuse was found to be a specific risk factor for dual diagnosis disorder (cases with psychiatric and substance use disorders) and for BN. Nearly all BN cases that experienced multiple or psychological child abuse, showed such comorbid anxiety or mood disorders.

DISCUSSION

We found tentative support for the self-medication hypothesis.

Does concurrent psychopathology at presentation influence response to treatment for bulimia nervosa?

Pub Med and Psych Lit were searched using the key terms 'outcome' and 'bulimia nervosa' for papers on outcome and bulimia nervosa (BN). The studies which examined any aspect of psychopathology are included and the findings reviewed. No robust findings emerged. This paper reviews the methodological problems that beset this area, and then examines in detail the relationship between other psychological dysfunctions and psychiatric co-morbidity and treatment outcome for BN. The psychological variables that most probably predict poorer outcome are low self-esteem, and low satisfaction with or perceived quality of friendships. With regard to psychiatric co-morbidity, there is no consistent relationship with any Axis I disorder. Most of the studies assessing Axis II dysfunction show that borderline symptom severity or cluster B personality disorder can impair outcome. The implications for clinical practice are discussed and directions for future research suggested.
