Perfectionism and eating disorders: current status and future directions

The literature examining the relation between perfectionism and eating disorders was reviewed and content and methodological comparisons were made with the perfectionism literature in anxiety disorders and depressive disorders. A PsychInfo search using the key words "perfectionism/perfect/perfectionistic," "anorexia," "bulimia," and "eating disorders" was performed and the generated list of papers was supplemented based on a review of reference lists in the papers. A total of 55 papers published between 1990 and 2005 were identified that assessed perfectionism among individuals with diagnosed eating disorders. The key research questions were distilled from these publications and empirical findings were summarized for each question, followed by a comparison with perfectionism papers in the anxiety and depressive disorder literatures. Also, key research design methodological parameters were identified and comparisons made across the three literatures: eating disorders, anxiety disorders, depressive disorders. The current review concludes with conceptual and methodological recommendations for researchers interested in perfectionism and eating disorders.     

Pain and emotion: new research directions

Recently, there has been growing interest in the relation between pain and emotion. Numerous recent studies have been conducted in this area. This article provides an introduction to this interesting area by highlighting selected research topics including studies on: stress and pain, negative emotional states and pain, catastrophizing and pain, the fear of pain, emotional regulation processes and pain, the effects of enhancing emotional regulation on pain, and the relation of emotional distress to treatment seeking in persons having pain. The article concludes with a discussion of important directions for future research in this area.     

Communication in context: new directions in communication research

By focusing attention almost exclusively on a single encounter, researchers have adopted a rather restricted view on studying communication in health care. After all, communication does not take place in a vacuum but is influenced by the context in which it takes place. We would therefore strongly recommend to broaden the perspective of communication research. In this respect, four lines of investigation are proposed, each guided by different theories. In the first, context is determined by the goals or targets aimed at by both parties in the medical encounter. The second concerns the context of time, referring to the influence of previous and future medical encounters. The third is set up around the organizational context in which an interaction takes place and the last defines context by looking at a medical encounter as a meeting between two multifaceted parties. Studying a medical encounter in its broader context is expected to provide answers to intriguing questions such as why health care professionals do not always act in conformity with the general approved standards of high quality communication and how the factor time span can be used more effectively in the medical encounter. Eventually, a broader context view will bridge the existing gap between theory and practice.     

The relationship between eating disorders and substance use: moving beyond co-prevalence research

The frequent comorbidity of eating disorders and substance use has been demonstrated consistently by research. Less is known about the basis of this relationship. A review of the literature indicates that the hypotheses proposed to clarify the etiological relationship between eating disorders and substance use have not been supported sufficiently or consistently by empirical evidence. General criticisms include: a lack of well developed models, a reliance on co-prevalence data, and a lack of integration of knowledge from eating disorder and substance use research. It is suggested that an understanding of the etiological relationship between eating disorders and substance use will be arrived at only after fundamental inquiries into the functional relationship between eating disorders symptomatology and substance use patterns have been conducted. A behavioral assessment approach is offered as a means of evaluating the functional relationship between eating disorder symptomatology and substance use.     

Psychosocial and pharmacological treatment of eating disorders: a review of research findings.

Research on the treatment of eating disorders has focused primarily on cognitive-behavioral therapy (CBT) and, more recently, interpersonal psychotherapy (IPT). Numerous studies have shown that CBT is helpful in reducing symptoms of bulimia nervosa and binge-eating disorder. In addition, CBT has been found to be superior or comparable to other psychotherapies in reducing bulimic symptoms. Preliminary findings indicate that CBT and IPT produce similar results at follow-up for bulimia nervosa and binge-eating disorder. Antidepressant medications are also useful in the treatment of bulimia nervosa and binge-eating disorder, but are less likely to result in remission of symptoms than CBT. The results from comparison studies are inconsistent, with modest evidence that combining antidepressant medication and psychotherapy produces greater improvement in bulimic symptoms. Limited research has been conducted on the treatment of anorexia nervosa, although preliminary studies suggest that psychotherapy and fluoxetine may be helpful in preventing relapse after weight restoration.     

Mortality in eating disorders

Crude mortality rates and mortality rates standardized against a British reference population have been calculated for a group of 460 consecutive patients with eating disorders seen between 1971 and 1981 in a tertiary referral centre for eating disorders. Crude mortality rates were 3.3% and 3.1% in the anorexia nervosa and bulimia nervosa groups respectively. Standardized rates demonstrated a six-fold increase in mortality in the anorexia nervosa group. The most common cause of death in this group was found to be suicide, with the risk of death remaining high for at least eight years after initial assessment. Specific associations of increased mortality were: being in the lowest weight group at the time of presentation, and having recurrent hospital admissions for eating problems.     

The importance of eating behavior in eating disorders

A disturbance in eating behavior is the defining characteristic of the clinical eating disorders, Anorexia Nervosa, Bulimia Nervosa, and Binge Eating Disorder. Surprisingly little research has been devoted to assessing objectively the nature of the eating disturbances in these disorders, to elucidating what factors contribute to the development and persistence of these disturbances, or to describing how they change with treatment. This review, which is based on a Mars lecture delivered at the 2010 meeting of the Society for the Study of Ingestive Behavior, reviews objective information about the nature of the disturbances of eating behavior in eating disorders. These data suggest that more detailed knowledge of eating behavior is an essential component of a full understanding of eating disorders and may provide a foundation for studies of pathophysiology and for the development of new treatment methods.     

Sleep and dreams in eating disorders

The results of several studies on sleep EEG and dreams in patients with eating disorders are presented and compared with the data obtained in patients with a major depression. The sleep pattern, which is characteristic of depression, could not be found in the eating disorder group. Regarding the cholinergic REM induction test, the depressive displayed a pronounced shortening of REM sleep latency. However, this biological marker, indicating a cholinergic hyperactivity in depression, could not be observed in patients with eating disorders. The content analysis of laboratory-recorded dreams yielded several differences between depression and eating disorders and also, more subtle, between anorexia and bulimia.     

Personality and eating disorders: a decade in review

Personality traits have been implicated in the onset, symptomatic expression, and maintenance of eating disorders (EDs). The present article reviews literature examining the link between personality and EDs published within the past decade, and presents a meta-analysis evaluating the prevalence of personality disorders (PDs) in anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED) as assessed by self-report instruments versus diagnostic interviews. AN and BN are both consistently characterized by perfectionism, obsessive-compulsiveness, neuroticism, negative emotionality, harm avoidance, low self-directedness, low cooperativeness, and traits associated with avoidant PD. Consistent differences that emerge between ED groups are high constraint and persistence and low novelty seeking in AN and high impulsivity, sensation seeking, novelty seeking, and traits associated with borderline PD in BN. The meta-analysis, which found PD rates of 0 to 58% among individuals with AN and BN, documented that self-report instruments greatly overestimate the prevalence of every PD.     

Psychotherapy for depression: current and future directions in research, theory, practice and public policy

This article is based on a symposium held at the 1998 Annual Meeting of Society for Psychotherapy Research (Snow Bird, Utah). Recognized experts addressed current and future directions in psychotherapy for depression from the perspectives of process and outcome research, basic research, theoretical models, clinical practice and training, and public policy. The specific issues discussed at the symposium included the strengths and limitations of major forms of psychotherapy; the therapeutic factors common and unique to different approaches; the future viability of current theories of depression; the role of treatment manuals in clinical practice and training; the development of new interventions based on basic research; and the priorities that should guide federal funding.     

The marital context of depression: research, limitations, and new directions

Despite improved recognition and treatment of mood disorders, understanding the mechanics of the interpersonal context of depressive disorders remains a vital area of scientific research. This paper reviews the findings on the marital context of depression by critically examining available empirical research on marital communication behaviors of depressed individuals. The specificity of the observed communication behaviors to depression versus marital distress or a general medical or psychiatric condition is examined. The paper also reviews the evidence on gender differences in marital communication of depressed individuals, depending on whether the husband or wife is depressed. The second part of the paper critically reviews three dominant interpersonal theories of depression as they refer to marital relationships. We discuss the need for theoretically-guided research and identify methodological and conceptual limitations of the current empirical literature, while highlighting the need for further theory development and refinement. Future interpersonal theories need to better account for depression epidemiology and the gender difference in rates of depression, as well as incorporate ideas from other theoretical perspectives.
