The Reliability and Validity of the Clinical Perfectionism Questionnaire in Eating Disorder and Community Samples.

BACKGROUND: Clinical perfectionism is a risk and maintaining factor for anxiety disorders, depression and eating disorders. AIMS: The aim was to examine the psychometric properties of the 12-item Clinical Perfectionism Questionnaire (CPQ). METHOD: The research involved two samples. Study 1 comprised a nonclinical sample (n = 206) recruited via the internet. Study 2 comprised individuals in treatment for an eating disorder (n = 129) and a community sample (n = 80). RESULTS: Study 1 factor analysis results indicated a two-factor structure. The CPQ had strong correlations with measures of perfectionism and psychopathology, acceptable internal consistency, and discriminative and incremental validity. The results of Study 2 suggested the same two-factor structure, acceptable internal consistency, and construct validity, with the CPQ discriminating between the eating disorder and control groups. Readability was assessed as a US grade 4 reading level (student age range 9-10 years). CONCLUSIONS: The findings provide evidence for the reliability and validity of the CPQ in a clinical eating disorder and two separate community samples. Although further research is required the CPQ has promising evidence as a reliable and valid measure of clinical perfectionism.

Profiling disordered eating patterns and body mass index (BMI) in the English general population.

PURPOSE: Little national evidence exists on disordered eating patterns in the UK. This study examined the prevalence and nature of disordered eating patterns in the National Adult Psychiatric Morbidity Survey 2007. METHOD: Responses to the screening tool for eating disorders (SCOFF) and body mass index (BMI) were analysed using latent class analysis (n = 7,001). Multinomial logistic regression explored the associations between latent classes and mental health comorbidities. RESULTS: The prevalence of possible eating disorders in England using the SCOFF was 6.3 %; this decreased to 1.6 % when accounting for the negative impact feelings about food had on the respondent's life. Five latent classes were identified: classes 1 and 2 resembled known eating disorders ('marginal anorexia' relating to anorexia nervosa and 'binge eaters' relating to bulimia nervosa/binge eating disorder); class 3 consisted of people who were obese, but did not experience eating problems; class 4 was morbidly obese, with an elevated risk of anxiety disorders; class 5 was labelled as 'normal eaters', with a low probability of eating problems and a normal BMI. CONCLUSIONS: Adults assigned to eating disorder type classes are at increased risk for mental health comorbidities and poorer social functioning. Information presented herein on clustering of disordered eating patterns may help clinicians identify those men and women risk for an eating disorder.

Anorexia nervosa and low weight EDNOS: a 10-year study of service consumption and outcome in a local specialised service for adults.

A 10-year retrospective case note study of adults with eating disorders at low weight examined levels of service consumption and the outcome in terms of body mass index. Records of 202 such patients, referred to a specialist secondary service, were studied. Just over one quarter of the patients failed to engage in treatment, attending five or fewer appointments. Of those who did engage, most were treated as out-patients and had an average contact with the service of almost 2.5 years and 46 sessions. Only about one in six patients was admitted as an in-patient at any time. These results suggest that most adults with eating disorder at low weight can be managed as out-patients. However, service providers should expect prolonged contact and high service consumption.

Micrographia and hypophonia in anorexia nervosa.

Micrographia is a condition, in which the sufferers write with small handwriting. Hypophonia is described as low volume speech. Both conditions have been described in neurological conditions, such as lesions in the deep white matter of the brain, Parkinson's disease etc. In this case report, we are presenting a 22-years-old female patient with anorexia nervosa who suffered from both these conditions. The patient also suffered from epilepsy. The onset of these symptoms, progress, and current status provides scope for discussing both the possible biological and psychodynamic etiology for these symptoms in this young woman.

Mortality and predictors of death in a cohort of patients presenting to an eating disorders service.

OBJECTIVE: The main aim was to investigate mortality across the spectrum of eating disorders presenting to a specialized service for adults in the UK. A secondary aim was to explore whether any clinical and demographic factors may be associated with increased risk. METHOD: We conducted a "tracing" study of 1,892 patients assessed by the Service between 1992 and 2004. We used the Office of National Statistics to identify all deaths recorded up to August 2007. We also compared deceased patients with matched controls in terms of a number of clinical and demographic variables at initial presentation to the service. RESULTS: Anorexia nervosa had a ten-fold increased risk of early death, but there was also evidence of increased risk in other groups of patients, including eating disorder not otherwise specified. A number of clinical factors predicted increased mortality risk, especially very low body mass index and the presence of alcohol misuse. DISCUSSION: The study confirms previous evidence of a markedly increased mortality risk for anorexia nervosa, but also suggests that the risk is not confined to this eating disorder and that greater attention needs to be focused on wider psychiatric comorbidity.

Effect of psychological treatment on attentional bias in eating disorders.

OBJECTIVE: The aims of these studies were (a) to investigate the relationship between attentional bias and eating disorders and (b) examine the impact of psychological treatment on attentional bias. METHOD: The first study compared performance on a pictorial dot probe of 82 female patients with clinical eating disorders and 44 healthy female controls. The second study compared the performance of 31 patients with eating disorder on the same task before and after receiving 20 weeks of standardized cognitive behavior therapy. Twenty-four patients with eating disorder served as wait-list controls RESULTS: With the exception of neutral shape stimuli, attentional biases for eating, shape, and weight stimuli were greater in the patient sample than the healthy controls. The second study found that attentional biases significantly reduced after active treatment only. CONCLUSION: Attentional biases may be an expression of the eating disorder. The question of whether such biases warrant specific intervention requires further investigation.

The severity and status of eating disorder NOS: implications for DSM-V.

"Eating disorder NOS" is the most common eating disorder encountered in outpatient settings yet it has been neglected. The aim of this study was to describe the characteristics of eating disorder NOS, establish its severity, and determine whether its high relative prevalence might be due to the inclusion of cases closely resembling anorexia nervosa or bulimia nervosa. One hundred and seventy consecutive patients with an eating disorder were assessed using standardised instruments. Operational DSM-IV diagnoses were made and eating disorder NOS cases were compared with bulimia nervosa cases. Diagnostic criteria were then adjusted to determine the impact on the prevalence of eating disorder NOS. Cases of eating disorder NOS comprised 60.0% of the sample. These cases closely resembled the cases of bulimia nervosa in the nature, duration and severity of their psychopathology. Few could be reclassified as cases of anorexia nervosa or bulimia nervosa. The findings indicate that eating disorder NOS is common, severe and persistent. Most cases are "mixed" in character and not subthreshold forms of anorexia nervosa or bulimia nervosa. It is proposed that in DSM-V the clinical state (or states) currently embraced by the diagnosis eating disorder NOS be reclassified as one or more specific forms of eating disorder.

Enhanced cognitive behaviour therapy for adults with anorexia nervosa: a UK-Italy study.

Anorexia nervosa is difficult to treat and no treatment is supported by robust evidence. As it is uncommon, it has been recommended that new treatments should undergo extensive preliminary testing before being evaluated in randomized controlled trials. The aim of the present study was to establish the immediate and longer-term outcome following "enhanced" cognitive behaviour therapy (CBT-E). Ninety-nine adult patients with marked anorexia nervosa (body mass index ≤ 17.5) were recruited from consecutive referrals to clinics in the UK and Italy. Each was offered 40 sessions of CBT-E over 40 weeks with no concurrent treatment. Sixty-four percent of the patients were able to complete this outpatient treatment and in these patients there was a substantial increase in weight (7.47 kg, SD 4.93) and BMI (2.77, SD 1.81). Eating disorder features also improved markedly. Over the 60-week follow-up period there was little deterioration despite minimal additional treatment. These findings provide strong preliminary support for this use of CBT-E and justify its further evaluation in randomized controlled trials. As CBT-E has already been established as a treatment for bulimia nervosa and eating disorder not otherwise specified, the findings also confirm that CBT-E is transdiagnostic in its scope.

Changes in alcohol intake in response to transdiagnostic cognitive behaviour therapy for eating disorders.

OBJECTIVE: The aim of this study was to examine how alcohol intake changes during and after transdiagnostic cognitive behaviour therapy for eating disorders (CBT-E). Additionally, the paper considers the relationship between alcohol consumption, eating disorder diagnosis and current major depressive episode at the time of first assessment. METHOD: One hundred and forty nine outpatients with an eating disorder (body mass index over 17.5) were divided into high or low alcohol intake groups (HIG and LIG) according to their intake at pre-treatment assessment. Their alcohol intake and eating disorder psychopathology were examined over the course of treatment and follow-up. RESULTS: There was no difference between the groups on response of the eating disorder to treatment. The HIG significantly reduced their alcohol intake following treatment whilst the intake of the LIG remained stable over the course of treatment and follow-up. There were no group differences in major depression and overall severity of eating disorder at baseline. CONCLUSIONS: The response to CBT-E was not influenced by baseline level of alcohol use. The mean alcohol intake of the heavy drinking subjects decreased without being specifically addressed by the treatment.

Can treatment trial samples be representative?

A catchment area-based sample of patients recruited for an eating disorder treatment trial was compared with patients from the same geographical area seen in the 12 months before and after the trial. The three samples were very similar. The research sample was representative of the usual clinic sample from which it had been selected and thus the results could be extrapolated with some confidence to other similar clinical settings. It is concluded that whilst treatment trials, by their very nature, have explicit and implicit inclusion and exclusion criteria with appropriate designs they can be usefully representative.

Transdiagnostic cognitive-behavioral therapy for patients with eating disorders: a two-site trial with 60-week follow-up.

OBJECTIVE: The aim of this study was to compare two cognitive-behavioral treatments for outpatients with eating disorders, one focusing solely on eating disorder features and the other a more complex treatment that also addresses mood intolerance, clinical perfectionism, low self-esteem, or interpersonal difficulties. METHOD: A total of 154 patients who had a DSM-IV eating disorder but were not markedly underweight (body mass index over 17.5), were enrolled in a two-site randomized controlled trial involving 20 weeks of treatment and a 60-week closed period of follow-up. The control condition was an 8-week waiting list period preceding treatment. Outcomes were measured by independent assessors who were blind to treatment condition. RESULTS: Patients in the waiting list control condition exhibited little change in symptom severity, whereas those in the two treatment conditions exhibited substantial and equivalent change, which was well maintained during follow-up. At the 60-week follow-up assessment, 51.3% of the sample had a level of eating disorder features less than one standard deviation above the community mean. Treatment outcome did not depend on eating disorder diagnosis. Patients with marked mood intolerance, clinical perfectionism, low self-esteem, or interpersonal difficulties appeared to respond better to the more complex treatment, with the reverse pattern evident among the remaining patients. CONCLUSIONS: These two transdiagnostic treatments appear to be suitable for the majority of outpatients with an eating disorder. The simpler treatment may best be viewed as the default version, with the more complex treatment reserved for patients with marked additional psychopathology of the type targeted by the treatment.

The measurement of impairment due to eating disorder psychopathology.

Eating disorders have a profound and highly specific impact on psychosocial functioning. The aim of this research was to develop a measure of such secondary impairment. A 16-item, self-report instrument was developed, the Clinical Impairment Assessment (CIA), which was designed to measure such impairment overall and in three specific domains (personal, cognitive, social). The psychometric properties of the instrument were evaluated using data collected in the context of a transdiagnostic treatment trial. The findings consistently supported the utility of the instrument with the CIA being shown to have high levels of internal consistency, construct and discriminant validity, test-retest reliability, and sensitivity to change. The CIA should be of value to clinicians when assessing patients with eating disorders and their response to treatment. It should also help inform epidemiological research.

Attentional bias in eating disorders.

OBJECTIVE: To examine the relationship between eating disorders and attentional biases. METHOD: The first study comprised 23 female patients with clinical eating disorders, women with high levels of anxiety (n = 19), and three female normal control groups comprising low (n = 31), moderate (n = 21), or high levels of shape concern (n = 23). The second study comprised 82 women with clinical eating disorders and 44 healthy controls. All participants completed measures of eating disorder psychopathology and completed a modified pictorial dot-probe task. RESULTS: In the first study, biases were found for negative eating and neutral weight pictures, and for positive eating pictures in women with eating disorders; these biases were greater than those found in anxious and normal controls. The second study replicated these findings and biases were also found for negative and neutral shape stimuli. CONCLUSION: It is concluded that future research should establish whether such biases warrant specific therapeutic interventions.

The associations between laxative abuse and other symptoms among adults with anorexia nervosa.

OBJECTIVE: The purpose of the current study was to examine the association between laxative abuse and other symptoms and features among adult patients presenting with anorexia nervosa. METHOD: One hundred and seventeen patients with anorexia nervosa were studied. Laxative abusers and nonabusers were compared. RESULTS: Compared with nonabusers, laxative-abusing patients had higher ratings on the Ineffectiveness, Body Dissatisfaction, and Drive for Thinness subscales on the Eating Disorders Inventory (EDI), as well as more depressive and somatization symptoms. There was an association between laxative abuse and low self-esteem. DISCUSSION: Laxative abuse appears to be associated with especially severe psychopathology and low self-esteem among subjects with anorexia nervosa.

An audit of a British sample of death certificates in which anorexia nervosa is listed as a cause of death.

OBJECTIVE: Anorexia nervosa is associated with an increased mortality rate. National mortality statistics based on statutory death certification are potentially an important source of information. However, there are reasons to believe that these statistics may be subject to significant errors. An audit of the quality of information and diagnosis was conducted on death certificates in which anorexia nervosa was mentioned. METHOD: The current study examined data from death certificates of people who died in England and Wales between 1993 and 1999. RESULTS: There were 230 such deaths, but only 128--just over one half--were rated as likely to be deaths associated with true anorexia nervosa. DISCUSSION: National mortality statistics derived from death certificates are a flawed source of information on deaths from anorexia nervosa when taken at face value. There may be both underreporting and overreporting. Detailed examination may improve their usefulness by reducing the overerreporting. It seems likely that the association of deaths with anorexia nervosa is systematically underreported.

Self-help for bulimic disorders: a randomised controlled trial comparing minimal guidance with face-to-face or telephone guidance.

BACKGROUND: There is great potential demand for treatment of bulimia nervosa and binge eating disorder. Skilled therapists are in short supply. Self-help and guided self-help based upon books have shown some promise as an economical alternative to full therapy in some cases. AIMS: To investigate the efficacy and effectiveness of self-help with and without guidance in a specialist secondary service. METHOD: A randomised controlled trial comparing three forms of self-help over 4 months with a waiting-list comparison group and measurement of service consumption over the subsequent 8 months. RESULTS: Self-help delivered with four sessions of face-to-face guidance led to improved outcome over 4 months. There is also some evidence to support the use of telephone guidance. A minority of participants achieved lasting remission of their disorder in relation to self-help, but there was no significant difference in final outcome between the groups after they had progressed through the stepped care programme. Patients initially offered guided self-help had a lower long-term drop-out rate. CONCLUSIONS: Guided self-help is a worthwhile initial response to bulimia nervosa and binge eating disorder. It is a treatment that could be delivered in primary care and in other non-specialist settings.

Chewing and spitting out food among eating-disordered patients.

OBJECTIVE: The symptom of chewing and spitting out food (CHSP) is fairly common among patients with eating disorders. The purpose of this study is to examine the associations of the symptom in patients with eating disorders. METHOD: Patients who reported CHSP were compared with those who did not. The relationship between CHSP and other symptoms was assessed by logistic regression analysis. RESULTS: CHSP was found in 22% of patients. Patients with anorexia nervosa and eating disorder not otherwise specified who reported CHSP showed more severe eating-related pathology. This was not so for bulimia nervosa patients with CHSP who differed only in reporting greater distortion of body image. Binging was not related to CHSP in any of the diagnostic groups. DISCUSSION: CHSP is a common symptom in all groups of patients with eating disorders. The symptom may serve different functions for different patients, depending on diagnosis.

A dialectical behavior therapy program for people with an eating disorder and borderline personality disorder--description and outcome.

OBJECTIVE: To describe and evaluate a full dialectical behavior therapy (DBT) program for people with comorbid eating disorder and borderline personality disorder. The program included a novel skills training module written especially for eating-disordered patients. METHOD: The program was run for 18 months. Days in hospital and major acts of self-harm were counted for the 18 months before and after DBT. RESULTS: There were no dropouts from the program. The patients seemed to benefit. Most patients were neither eating disordered nor self-harming at follow-up. DISCUSSION: Full DBT is an expensive and demanding treatment but deserves consideration for patients with an eating disorder and co-morbid borderline personality disorder and self-harm. There is a need for a more systematic and thorough evaluation.

Remission, recovery, relapse, and recurrence in eating disorders: conceptualization and illustration of a validation strategy.

In a consensus-building process a group of experts from 19 European countries (COST Action B6) adapted the terms partial and full remission, relapse, recovery, and recurrence according to principles described by Frank et al. for depression. The empirical validity of the operationalizations was illustrated by longitudinal data on the post treatment course of 233 anorectic and 422 bulimic patients (diagnosed according to DSM-IIIR) from the German Project TR-EAT. These data were collected 2.5 years after admission using the Longitudinal Interval Follow-up Evaluation (LIFE) and statistically explored by survival-analysis. It was demonstrated that these consensus definitions measure what they intend to measure. They open a longitudinal perspective in that one can learn not only whether, but also when and with what probability patients change for the better or worse. Data suggest that persistence of symptom improvement has different implications for anorexia and bulimia nervosa. For example, relapse prevention would be most beneficial for bulimic patients for about 4 months after key symptoms remit, while this would be of less importance for anorexic patients. It is discussed whether and how this longitudinal approach can contribute to an empirically based rationale for targeted and individualized treatment.
